  6. Prospects of Applying Feed Processing Technologies Based on Industrial Plantation

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available The potency of plantation sectors (palm oil, sugar cane and cacao as alternative feed resources for ruminants has been acknowledged since 20 – 25 years ago. However, the level of utilization of these feeds in small ruminant production system has been very low and sporadic. The typical chemical and physical characteristics of most of those feedstuffs required some steps of processing in order to improve their nutritional quality and to ease their handling. Small ruminants, like sheep and goats have relatively higher metabolic energy requirement per kg BW and anatomically have lower gut capacity to process lignocelluose materials compared to large ruminants. It is, therefore, these animals nutritionally face more constraints in handling lignocellulose and bulky materials mostly found in industrial by products or crop-residues from plantations. Physical processes (chopping, phyiscal separation, hydrothermal, chemical processes (ammoniation, hydrolyses and oxidative treatments and bio-conversions (fermentation, ensiling have been recommended as alternative technologies in maximizing the utilization of those feedstuffs for small ruminant animals. The principal mechanisms of those treatments are: (i breaking the linkages between structural carbohydrate and lignin so that it could be easily digested by the animal enzyme systems and (ii preserving the material from being spoilage due to its high moisture content or for feed stocking purposes. Priorities for choosing the most effective processing technology for implementation or adoption is depent largely on the scale of feed production. Ammoniation, chopping, physical separation, ensiling or bio-conversion are several technologies mostly recommended for small scale operation in situ. These alternative technologies should be able to be adopted by small-holders living around the plantation area. The commercial or large scale feed production could be implemented by the plantation industry by giving high

The paper starts with outlining main characteristics of PI which distinguish it from other types of L2 grammar instruction. Then, a large body of research attempting to investigate the relative efficacy of PI is scrutinized. The paper concludes with a number of important issues that future studies on PI need to address.

  16. Synthesis of Collaborative Learning Processes with Technology Based Education to Enhance Classroom Teaching

    Ghosh, Sumit

    2016-07-01

    A major hurdle in school education in India is the presence of large number of teachers who are inexperienced and have merely taken up the profession of teaching only after exhausting all avenues or getting rejected from all quarters. Empowering and training such teachers with information is a herculean task. Students tend to pay attention and show enthusiasm in learning when they view the class as relevant to themselves and connected to their interests. The current teaching-learning methods for teaching science and astronomy have become obsolete and require a major overhaul. A teaching-learning process which concentrates on an explorative-collaborative-comprehending methodology with simultaneous combination of technology has been developed with the objective to reignite the scientific temper among the future budding scientists. Attaining this goal will be possible when instructors adopt a bottom-up approach, which involves understanding the student's needs, designing flexible course content and synchronizing teaching techniques that focus on increasing student engagement by making the learning experience meaningful and purposeful. The International Year of Light (IYL 2015) is a global initiative that highlights to the citizens of the world the importance of light and optical technologies in their lives, for their futures, and for the development of society. One of the strong legacies left by the 2009 International Year of Astronomy was to use Astronomy in making the world a better place. On the eve of IYL 2015, an Optical Society funded outreach program, 'Spark of Light' was organised for under-privileged school children by using the explorative-collaborative-technology based mechanism and make them understand the nature and properties of light with emphasis on how Astronomy has been crucial for the evolution of sophisticated technology. A major paradigm shift from our previous program was the engagement of such untrained teachers in each and every aspect of

  17. Matlab-supported undergraduate image processing instruction

    Dawant, Benoit M.

    1998-06-01

    More and more often, undergraduate students express the desire to take a course on image processing. These students will learn the most if the theory and algorithms covered in class can be not only illustrated through examples shown by the instructor during class but also coded, tested, and evaluated by the class participants. In the past, the major hurdle to developing a hands-on approach to image processing instruction has been the amount of programming required to implement relatively simple applications. Typical undergraduate students lack experience with low level programming languages and time is spent teaching the language itself rather than experimenting with the algorithms. High level and interpreted programming languages such as Matlab permit to address this question. Even with very little practical exposure to the language, students can rapidly develop the level of skills required to implement a range of image processing algorithms. This presentation will go over the material covered in a senior level introductory course in image processing taught at Vanderbilt University. The course itself is taught in a traditional way but it is supported by laboratories during which students are asked to implement algorithms ranging from connected component labeling to image deblurring. The students are also assigned projects that span several weeks. Examples of such assignments and projects are presented.

    2013-09-01

    Full Text Available This article analyzes the sensemaking processes of organizational identity and technological capabilities that are facilitators of innovation at New-Technology-Based Firms (NTBFs. The research proposal points out that in this kind of organization, the knowledge transferred by these processes simultaneously addresses two core aspects: their organizational identity and technological capabilities. From a theoretical point of view, our study links two conceptual frameworks (organizational identity and technological capabilities, rarely mentioned together in the preceding research. From a practical point of view, the findings identify these processes and suggest that in this kind of organization both take place simultaneously, which could help stakeholders improve their management. Hence, members and managers of these organizations should take these processes into account as a framework to achieve competitiveness and therefore success.

    2006-01-01

    CAPP(Computer Aided Process Planning) has already become the bottleneck of CAD/CAM system. Present two-dimensional CAPP system which is used in the enterprise needs to be input information and data again, because it can not draw data from CAD(Computer Aided Design)model automatically after building CAD model and drawing. This has influenced extensive use of CAPP system because of its low efficiency. In this paper, three-dimensional model is built by using the parametric method, the process file can be produced directly through drawing corresponding characteristic and parameter from the model with the aid of process database. This improves the efficiency of product development. Visual C++ 6.0 and SQL Server 2000 are used to develop WTJDCAPP prototype system based on component model and SolidWorks three-dimensional CAD platform. Engine valve-seat is taken as concrete object to validate of the technology.

    2013-01-01

    Full Text Available Input Processing (IP proposed by VanPatten (1993, was innovated based on Krashen’s (1982 input hypothesis. In IP model, principles are stated that describe how learners either miss grammatical markers in the input or how they get them wrong (VanPatten, 2002b. Based on this model, learners process input for meaning before form. Processing Instruction (PI, an explicit focus on form that is informed by the model of IP, is a practical solution to IP model. The goal of PI is to help L2 learners derive richer intake from input by having them engage in structured input activities that push them away from the strategies they normally use to make form-meaning connections (Wong, 2004. This article intends to study  the definitions of IP and PI as well the issues of IP and PI, including the principles of IP,  features and goal of PI, and input used in PI (Structured input activities, and then to introduce difference between the terms IP and PI.

    Duda, A.; Ward, S.; Young, M.

    2012-02-01

    This technical report details the processing schedule used to fabricate Inverted Metamorphic Multijunction (IMM) concentrator solar cells at The National Renewable Energy Laboratory (NREL). These devices are used as experimental test structures to support the research at NREL that is focused on increasing the efficiency of photovoltaic power conversion. They are not intended to be devices suitable for deployment in working concentrator systems primarily because of heat sinking issues. The process schedule was developed to be compatible with small sample sizes and to afford relatively rapid turn-around times, in support of research efforts. The report describes the use of electro deposition of gold for both the back and front contacts. Electro-deposition is used because of its rapid turn around time and because it is a benign metallization technique that is seldom responsible for damage to the semiconductors. The layer transfer technique is detailed including the use of a commercially available adhesive and the etching away of the parent gallium arsenide substrate. Photolithography is used to define front contact grids as well as the mesa area of the cell. Finally, the selective wet chemical etchant system is introduced and its use to reveal the back contact is described.

    Full Text Available Programmable Logic Controller (PLC is a device that allows an Electro-Mechanical engineer to automate his mechanical process in an efficient manner. Safety critical high speed application requires quick response. In order to improve the speed of executing PLC instructions, the IL processor is researched. Hierarchical approach has been used so that basic units can be modeled using behavioral programming. These basic units are combined using structural programming. Hardwired control approach is used to design the control unit. The proposed IL (Instruction List processor work upon our developed IL instructions which are compatible with the programming language IL according to the norm IEC 61131-3. This can accelerate the instructions execution, ultimately improve real-time performance comparing to the traditional sequential execution of PLC program by giving quick response at such safety critical high speed application. The design is to be implemented on FPGA for verification purpose. To validate the advance of the proposed design, two ladder programs are compiled to the instruction set of proposed IL processor as well as in IL programming language.

    Welzel, Manuela

    1997-09-01

    During the 1970s, student-centred instruction—that is, “play orientation in physics education” (Spielorientierter Unterricht)—was at the centre of curriculum development at the Institute of Physics Education in Bremen. During the past decade, we investigated this kind of instruction with a particular focus on students' learning processes using a situated cognition perspective. Our research group at the Institute conducted several empirical studies of physics learning for different age groups. The aim of these case studies was to construct detailed understandings of how individual learning processes unfold. On the basis of these studies, we attempt to design physics lessons more effectively than they have been in the past. This paper exemplifies our approach providing information about the theoretical and methodological frameworks, the main outcomes of our studies; and reflections about the possibilities for “more effective” student-centred instruction.

    In this paper, we propose a new porous polymer printing technology based on CBA(chemical blowing agent), and describe the optimization process according to the process parameters. By mixing polypropylene (PP) and CBA, a hybrid CBA filament was manufactured; the diameter of the filament ranged between 1.60 mm and 1.75 mm. A porous polymer structure was manufactured based on the traditional fused deposition modelling (FDM) method. The process parameters of the three-dimensional (3D) porous polymer printing (PPP) process included nozzle temperature, printing speed, and CBA density. Porosity increase with an increase in nozzle temperature and CBA density. On the contrary, porosity increase with a decrease in the printing speed. For porous structures, it has excellent mechanical properties. We manufactured a simple shape in 3D using 3D PPP technology. In the future, we will study the excellent mechanical properties of 3D PPP technology and apply them to various safety fields.

    Advanced microgravity plant biology research and life support system development for the spacecraft environment are critically hampered by the lack of a technology base. This inadequacy stems primarily from the fact that microgravity results in a lack of convective currents and phase separation as compared to the one gravity environment. A program plan is being initiated to develop this technology base. This program will provide an iterative flight development effort that will be closely integrated with both basic science investigations and advanced life support system development efforts incorporating biological processes. The critical considerations include optimum illumination methods, root aeration, root and shoot support, and heat rejection and gas exchange in the plant canopy.

    提出了一种使用MATLAB仿真工具箱Simulink与动态模拟软件Aspen Dynamics相互调用来实现化工过程监测的方法。该方法具有以下优点:Aspen Dynamics能够快速建立精确的动态模型,具有完善的物性数据库,同时可以方便根据实际的化工过程对模型进行调整;使用Simulink仿真工具箱可以实时采集数据作为模型输入,同时完成对数据的必要处理。为了检测方法的可行性,将其应用于一个虚拟精馏过程来检验监测效果,结果表明,其可以实现对存在生产计划变更过程的故障监测和无生产计划变更过程中故障的监测。%A chemical process monitoring method using Simulink Toolbox of MATLAB to invoke Aspen Dynamics to dynamically simulate the chemical process was proposed. In most of the previous literatures about model-based fault detection, the mechanistic model should be built by hand,which is very time-consuming and requires the user to have a high professional quality. Using this method can build dynamics simulation for chemical in a quick and accurate way using Aspen Dynamics even the people who don’t have high professional quality in chemical engineering, meanwhile, the data collected from the factory often require correction, using Simulink Toolbox can conveniently correct the model data and measured data, at the same time the real-time factory data was collected as input data for dynamics simulation in order to achieve real-time process monitoring. The method was tested using a virtual distillation process in Aspen Dynamics, the results show that it can detect faults in chemical process with and without production change. Because the fault data also comes from a distillation process using Aspen Dynamics, the simulate data and the measured data without process fault are very similar, the method to correct the simulation data was not include.

  17. Authenticity in the process of learning about Instructional Design

    2010-05-01

    Full Text Available Authentic learning is touted as a powerful learning approach, particularly in the context of problem-based learning (Savery, 2006. Teaching and learning in the area of instructional design appears to offer a strong fit between the tenets of authentic learning and the practice of instructional design. This paper details the efforts to broaden and deepen the understanding of instructional design through a service learning approach to teaching, emphasizing authentic learning and assessment. Students are teamed and assigned to an actual contract with an external client under the supervision of the instructor who acts as project manager for the group. Contracts are negotiated to deliberately offer instructional design services to clients who would not otherwise be able to afford them, such as community-based non-profit groups. The reasons are two fold: first, we want to avoid competing for contracts that would interfere with the business of commercial instructional design groups and contractors; second, we want to impress on our students the idea that instructional design has social importance beyond the profit/loss and cost/effectiveness orientation of many instructional design businesses. In this way, we promote the idea that instructional designers are agents of social change, and their influence crosses interpersonal, professional, institutional and societal dimensions of change (Schwier, Campbell and Kenny, 2007.  Résumé : L’apprentissage authentique est présenté comme une approche efficace en apprentissage, en particulier dans le contexte de l’apprentissage par problèmes (Savery, 2006.

  20. IPULOC - Exploring Dynamic Program Locality with the Instruction Processing Unit for Filling Memory Gap

    Institute of Scientific and Technical Information of China (English)

    黄震春; 李三立

    2002-01-01

    Memory gap has become an essential factor influencing the peak performance of high-speed CPU-based systems. To fill this gap, enlarging cache capacity has been a traditional method based on static program locality principle. However, the order of instructions stored in I-Cache before being sent to Data Processing Unit (DPU) is a kind of useful information that has not ever been utilized before. So an architecture containing an Instruction Processing Unit (IPU) in parallel with the ordinary DPU is proposed. The IPU can prefetch,analyze and preprocess a large amount of instructions otherwise lying in the I-Cache untouched.It is more efficient than the conventional prefetch buffer that can only store several instructions for previewing. By IPU, Load Instructions can be preprocessed while the DPU is executing on data simultaneously. It is termed as "Instruction Processing Unit with LOokahead Cache"(IPULOC for short) in which the idea of dynamic program locality is presented. This paper describes the principle of IPULOC and illustrates the quantitative parameters for evaluation.Tools for simulating the IPULOC have been developed. The simulation result shows that it can improve program locality during program execution, and hence can improve the cache hit ratio correspondingly without further enlarging the on-chip cache that occupies a large portion of chip area.

    Carter, Nina Leann

    The purpose of this qualitative multiple-case study was to explore the transfer of learning process in student teachers. This was carried out by focusing on information learned from an elementary science methods and how it was transferred into classroom instruction during student teaching. Participants were a purposeful sampling of twelve elementary education student teachers attending a public university in north Mississippi. Factors that impacted the transfer of learning during lesson planning and implementation were sought. The process of planning and implementing a ten-day science instructional unit during student teaching was examined through lesson plan documentation, in-depth individual interviews, and two focus group interviews. Narratives were created to describe the participants' experiences as well as how they plan for instruction and consider science pedagogical content knowledge (PCK). Categories and themes were then used to build explanations applying to the research questions. The themes identified were Understanding of Science PCK, Minimalism, Consistency in the Teacher Education Program, and Emphasis on Science Content. The data suggested that the participants lack in their understanding of science PCK, took a minimalistic approach to incorporating science into their ten-day instructional units, experienced inconsistencies in the teacher education program, and encountered a lack of emphasis on science content in their field experience placements. The themes assisted in recognizing areas in the elementary science methods courses, student teaching field placements, and university supervision in need of modification.

    Trujillo, Caleb M; Anderson, Trevor R; Pelaez, Nancy J

    2016-06-01

    In biology and physiology courses, students face many difficulties when learning to explain mechanisms, a topic that is demanding due to the immense complexity and abstract nature of molecular and cellular mechanisms. To overcome these difficulties, we asked the following question: how does an instructor transform their understanding of biological mechanisms and other difficult-to-learn topics so that students can comprehend them? To address this question, we first reviewed a model of the components used by biologists to explain molecular and cellular mechanisms: the MACH model, with the components of methods (M), analogies (A), context (C), and how (H). Next, instructional materials were developed and the teaching activities were piloted with a physical MACH model. Students who used the MACH model to guide their explanations of mechanisms exhibited both improvements and some new difficulties. Third, a series of design-based research cycles was applied to bring the activities with an improved physical MACH model into biology and biochemistry courses. Finally, a useful rubric was developed to address prevalent student difficulties. Here, we present, for physiology and biology instructors, the knowledge and resources for explaining molecular and cellular mechanisms in undergraduate courses with an instructional design process aimed at realizing pedagogical content knowledge for teaching. Our four-stage process could be adapted to advance instruction with a range of models in the life sciences.

    Full Text Available This study was conducted to systematically track and benchmark upper primary school students‟ ESL reading comprehension ability and subsequently generate data at the micro and macro levels according to individual achievement, school location, gender and ethnicity at the school, district, state and national levels. The main intention of this initiative was to provide information to assist ESL teachers about their students‟ reading ability and to determine students' reading comprehension performance standards. The auto generated data is expected to facilitate classroom instructional process without necessitating teachers to prepare test materials or manage data of their students‟ reading comprehension track records. The respondents were 1,514 Year 5 students from urban and rural schools from a district in northern Malaysia. The idea was conceptualised through a series of tests and development of the Reading Evaluation and Decoding System (READS for Primary Schools. The findings indicated that majority of the respondents were „below standard‟ and „at academic warning‟. We believe the generated data can assist the Ministry of Education to develop better quality instructional processes that are evidence based with a more focused reading instruction and reading material to tailor to the needs of students.

    2013-01-01

    Full Text Available The ability to map instructions running in a microprocessor to a reconfigurable processing unit (RPU, acting as a coprocessor, enables the runtime acceleration of applications and ensures code and possibly performance portability. In this work, we focus on the mapping of loop-based instruction traces (called Megablocks to RPUs. The proposed approach considers offline partitioning and mapping stages without ignoring their future runtime applicability. We present a toolchain that automatically extracts specific trace-based loops, called Megablocks, from MicroBlaze instruction traces and generates an RPU for executing those loops. Our hardware infrastructure is able to move loop execution from the microprocessor to the RPU transparently, at runtime, and without changing the executable binaries. The toolchain and the system are fully operational. Three FPGA implementations of the system, differing in the hardware interfaces used, were tested and evaluated with a set of 15 application kernels. Speedups ranging from 1.26 to 3.69 were achieved for the best alternative using a MicroBlaze processor with local memory.

    Full Text Available Abstract This paper serves as a report on a qualitative study that was conducted in a language center in Colombia, with the aim of exploring the integration of computer technology into two EFL classes. This process involved the transformation of a traditional communicative language syllabus into a computer-technology oriented one which included the use of virtual communities, E-mail, Blogs and an instant-messaging application. Results of this study led to a critical discussion of the role of teachers and institutions when implementing computer technology. Other findings of this study suggest that some of the participants tended to choose computer-mediated communication over face-to-face interaction when communicating in EFL. It could also be observed that the participants expressed their willingness to continue using computer technology in future language instruction.Resumen Este artículo reporta una investigación de tipo cualitativo que se realizó en un centro de enseñanza del inglés en Colombia y cuyo objetivo fue explorar la implementación de la tecnología en dos clases de enseñanza del inglés como lengua extranjera. Este proceso se llevo a cabo por medio de modificaciones curriculares que llevaron a la inclusión de correo electrónico, foros de discusiones y aplicaciones de mensajería instantánea como medios para facilitar proyectos en el aula. Los resultados llevan a replantear el rol de docentes e instituciones para contribuir a la integración de las TIC cuando estas han sido excluidas curricularmente. De la misma manera, los resultados sugieren que algunos participantes preferirían seguir utilizando tecnología, y comunicarse por medios electrónicos en lengua extranjera en lugar de sostener conversaciones vis-à-vis entre sus compañeros de clase.

    The main purpose of this study was to explore the effects of long-term constructivist-oriented science instruction on elementary school students' process of constructing cognitive structures. Furthermore, such effects on different science achievers were also investigated. The subjects of this study were 69 fifth graders in Taiwan, while they were assigned to either a constructivist-oriented instruction group or a traditional teaching group. The research treatment was conducted for 5 months, including six instructional units, and students' cognitive structures were probed through interviews coupled with a metalistening technique'' after the instruction of each unit. The interview narratives were transcribed into the format of flow maps. In addition, the information processing modes shown in the flow maps were also investigated through a series of content analyses. The findings showed that the students in the constructivist-oriented instruction group attained significantly better learning outcomes in terms of the extent and integration of their cognitive structures, metacognition engagement, and the usage of information processing strategies. Moreover, it was also revealed that both high achievers and low achievers benefited from the constructivist-oriented instructional activities, but in different ways. For example, both high achievers and low achievers in the constructivist-oriented instruction group attained better usage of information processing strategies than their counterparts in traditional teaching group did; but only high achievers displayed better usage of higher order information processing modes (i.e., inferring or explaining) than their counterparts in traditional teaching group did. The results in this study finally suggest a four-stage model for students' process of constructing cognitive structure under the constructivist-oriented science instruction, including cognitive structure acquisition, metacognition enrichment, cognitive structure

    Lawrence Livermore National Laboratory's Engineering Directorate has two primary discretionary avenues for its investment in technologies: the Laboratory Directed Research and Development (LDRD) program and the ''Tech Base'' program. This volume summarizes progress on the projects funded for technology-base efforts in FY2004. The Engineering Technical Reports exemplify Engineering's more than 50-year history of researching and developing (LDRD), and reducing to practice (technology-base) the engineering technologies needed to support the Laboratory's missions. Engineering has been a partner in every major program and project at the Laboratory throughout its existence, and has prepared for this role with a skilled workforce and technical resources. This accomplishment is well summarized by Engineering's mission: ''Enable program success today and ensure the Laboratory's vitality tomorrow''. LDRD is the vehicle for creating those technologies and competencies that are cutting edge. These require a significant level of research or contain some unknown that needs to be fully understood. Tech Base is used to apply those technologies, or adapt them to a Laboratory need. The term commonly used for Tech Base projects is ''reduction to practice''. Tech Base projects effect the natural transition to reduction-to-practice of scientific or engineering methods that are well understood and established. They represent discipline-oriented, core competency activities that are multi-programmatic in application, nature, and scope. The objectives of technology-base funding include: (1) the development and enhancement of tools and processes to provide Engineering support capability, such as code maintenance and improved fabrication methods; (2) support of Engineering science and technology infrastructure, such as the installation or integration of a new capability; (3) support for technical and

    Given the wide reach and extensive capabilities of the Internet, it is increasingly being used to deliver comprehensive behavioral and mental health intervention and prevention programs. Their goals are to change user behavior, reduce unwanted complications or symptoms, and improve health status and health-related quality of life. Internet interventions have been found efficacious in addressing a wide range of behavioral and mental health problems, including insomnia, nicotine dependence, obesity, diabetes, depression, and anxiety. Despite the existence of many Internet-based interventions, there is little research to inform their design and development. A model for behavior change in Internet interventions has been published to help guide future Internet intervention development and to help predict and explain behavior changes and symptom improvement outcomes through the use of Internet interventions. An argument is made for grounding the development of Internet interventions within a scientific framework. To that end, the model highlights a multitude of design-related components, areas, and elements, including user characteristics, environment, intervention content, level of intervention support, and targeted outcomes. However, more discussion is needed regarding how the design of the program should be developed to address these issues. While there is little research on the design and development of Internet interventions, there is a rich, related literature in the field of instructional design (ID) that can be used to inform Internet intervention development. ID models are prescriptive models that describe a set of activities involved in the planning, implementation, and evaluation of instructional programs. Using ID process models has been shown to increase the effectiveness of learning programs in a broad range of contexts. ID models specify a systematic method for assessing the needs of learners (intervention users) to determine the gaps between current

    Image processing can be considered as signal processing in two dimensions (2D). Filtering is one of the basic image processing operation. Filtering in frequency domain is computationally faster when compared to the corresponding spatial domain operation as the complex convolution process is modified as multiplication in frequency domain. The popular 2D transforms used in image processing are Fast Fourier Transform (FFT), Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT). The common values for resolution of an image are 640x480, 800x600, 1024x768 and 1280x1024. As it can be seen, the image formats are generally not a power of 2. So power of 2 FFT lengths are not required and these cannot be built using shorter Discrete Fourier Transform (DFT) blocks. Split radix based FFT algorithms like Good-Thomas FFT algorithm simplifies the implementation logic required for such applications and hence can be implemented in low area and power consumption and also meet the timing constraints thereby operating at high frequency. The Good-Thomas FFT algorithm which is a Prime Factor FFT algorithm (PFA) provides the means of computing DFT with least number of multiplication and addition operations. We will be providing an Altera FPGA based NIOS II custom instruction implementation of Good-Thomas FFT algorithm to improve the system performance and also provide the comparison when the same algorithm is completely implemented in software.

    Full Text Available The Math Emporium, opened in 1997, is an open 7000-squaremeter facility with 550+ workstations arranged in an array of widely spaced hexagonal "pods", designed to support group work at the same time maintaining an academic air. We operate it 24/7 with math support personnel in attendance 12 hours per day. Students have access to online course resources at all times, from anywhere. We have used this unique asset to transform traditional classroom-based courses into technology based learning programs that have no class meetings at all. The structure of the program is very different from the conventional one, having a new set of expectations and motivations. The results include: more effective students, substantial cost savings, economies of scale and scope and a stream-lined process for creating new on-line courses.

    In order to reduce CO{sub 2} emission to prevent global warming, the most promising way for electric generation in the Northeast Asia is to introduce cogeneration and {open_quotes}repowering{close_quotes} technologies based on high temperature gas turbines fueled by natural gas. Especially the old type coal burning boiler-steam turbine plants should be retrofit by introducing gas turbines to become highly efficient combined cycle. Same technologies should be applied to the old garbage incineration plants and/or even to the nuclear power plants. The exhaust heat or steam should become much increased and it should be utilized as the process heat for industries or heat supply as the distinct heating or cooling for residential area. This paper introduces a brief survey of these new technologies.

    Full Text Available Nowadays increasing importance of science process skills and laboratory approach in science education requires the acquisition of scientific process skills that teachers should have been gained those skills during pre-service training courses to transfer their students. Peer instruction, which results in effective outcomes for concept teaching recently, comprises another aspect of this study. The aim of this study is to determine whether scientific process skills laboratory approach, which is supported with peer instruction, is an effective method to improve some high level scientific process skills of pre-service teachers. Single group experimental research design was used in this study. Data were collected by using open ended experiment worksheets, student rubrics, experiment evaluation questionnaire and semi-structured interviews during peer instruction supported scientific process skills laboratory approach in which third year primary science education students at Balikesir University took part in six weeks long application. Findings of the study show that pre-service teachers’ skills of determining variables, changing and controlling variables and making inferences improved while constructing hypotheses and setting up experiment skills were not improved. It is suggested that peer instruction supported scientific process skills laboratory approach should be used to acquire scientific process skills.

    2004-04-01

    As wireless video products evolve, they demand more sophisticated processing at higher resolutions and frame rates. Computational performance and energy efficiency have become critical design issues. This paper presents the Quantized Color Pack eXtension (QCPX) combined with a loop unrolling (LU) technique to improve execution performance and energy efficiency of color image and video processing applications. QCPX applied to a 32-bit datapath processor supports parallel operations on two packed 16-bit YCbCr (Y: luminance, Cr and Cb: chrominance) color pixels, providing greater subword-level parallelism by increasing the number of smaller color pixels packed into a word. Instruction-level parallelism can be further enhanced through loop unrolling. These techniques provide greater performance and efficiency for multimedia workloads on mobile systems. Experimental results on a set of media benchmark applications indicate that the LU plus QCPX-optimized version achieves a speedup ranging from 3.8 to 7.9 while reducing the energy consumption from 76% to 87% over the baseline version on identically configured, dynamically scheduled ILP superscalar processors. The LU plus QCPX-optimized version also outperforms the LU plus MDMX-like (MIPS"s multimedia extension) version.

    Full Text Available Learning invariably proceeds by relating new facts to the already familiar and present in the conceptual structure. In the context of FL study the familiar is, of course, the student’s mother tongue. Drawing on the learner’s L1 (or another mastered tongue and showing comparisons and contrasts between the languages mirrors, facilitates and accelerates the processes which occur independently in his/her mind. At the same time, when in a new situation, we look for familiar orientation points and similarities owing to our instinctive need for safety. This is also why the target language should literally be taught in the framework of the learner’s L1. Instruction in the Language Interface Model (LIM; Gozdawa-Gołębiowski 2003a,b, 2004a,b, 2005 proceeds from an explication of how relevant rules operate in the students’ L1 through an explanation of corresponding L2 rules and subsequent interface formation, modifying the L1 rule to accommodate L2 data, with practice first expecting the learner to apply the FL rules to L1 examples before moving to more traditional exercises, to finally end with competence expansion – integrating the two competences, leading to the development of multicompetence and allowing for the obliteration of the rules governing the structure of the utterance from the learner’s conscious mind.

    Hsu, Ying-Shao

    The purpose of this research was to develop a computer-based instructional simulation of adiabatic processes and to study the effects of selected characteristics of the simulation on students conceptual development, problem solving and transfer. To study these issues the related literature was reviewed, a simulation was developed and a two-pronged research study was employed. From the review of literature and constructivist theory, a simulation to facilitate active and situated learning was developed. It included the features of multiple representations, interaction, and authentic tasks. The subjects for the study were students enrolled in a beginning meteorology course at Iowa State University. An experimental study was conducted comparing achievement measures of two groups who used different versions of the simulation and a control group who did not use the simulation. In addition, selected students were interviewed to gain a deeper understanding of their use of the simulation. The performances of the groups were compared on scores from a posttest and weather forecasts. As expected, since the simulation was not integrated into classroom activities, there were no statistically significant differences between the groups. Interview data supported the design and future use of the simulation. Four of the five students saw the task as being authentic. The multiple representations were used by the students to construct knowledge across representations and to choose their own mode of representation for exploring the simulation. Of the five students interviewed, only one had used an effective problem solving strategy. This student also demonstrated a better understanding of how to transfer newly-gained knowledge to weather forecast exercises. Two other students were poised for improvement of their problem solving strategies, having the basic strategy but needing refinement, and the other two were in need of basic instruction and guidance. This study clearly revealed a

    Children with ADHD exhibit clinically impairing inattentive behavior during classroom instruction and in other cognitively demanding contexts. However, there have been surprisingly few attempts to validate anecdotal parent/teacher reports of intact sustained attention during 'preferred' activities such as watching movies. The current investigation addresses this omission, and provides an initial test of how ADHD-related working memory deficits contribute to inattentive behavior during classroom instruction. Boys ages 8-12 (M = 9.62, SD = 1.22) with ADHD (n = 32) and typically developing boys (TD; n = 30) completed a counterbalanced series of working memory tests and watched two videos on separate assessment days: an analogue math instructional video, and a non-instructional video selected to match the content and cognitive demands of parent/teacher-described 'preferred' activities. Objective, reliable observations of attentive behavior revealed no between-group differences during the non-instructional video (d = -0.02), and attentive behavior during the non-instructional video was unrelated to all working memory variables (r = -0.11 to 0.19, ns). In contrast, the ADHD group showed disproportionate attentive behavior decrements during analogue classroom instruction (d = -0.71). Bias-corrected, bootstrapped, serial mediation revealed that 59% of this between-group difference was attributable to ADHD-related impairments in central executive working memory, both directly (ER = 41%) and indirectly via its role in coordinating phonological short-term memory (ER = 15%). Between-group attentive behavior differences were no longer detectable after accounting for ADHD-related working memory impairments (d = -0.29, ns). Results confirm anecdotal reports of intact sustained attention during activities that place minimal demands on working memory, and indicate that ADHD children's inattention during analogue classroom instruction is related, in large part

    2010-11-01

    In Higher Education, performance and Teaching-Learning (T-L) contexts are highly current concerns. Based on the DEDEPRO model, interdependence can be established between instructional contexts and levels of performance as they relate to the T-L process. Partitipants were 2020 pupils from two Spanish universities. Measurements of both variables were used in a quasi-experimental and correlational design. The univariate and causal analyses showed the effect of context on the T-L process and on performance; thus, the interdependent relationships between the latter and perception of the T-L process. Partial interaction effects also appeared, as well as a causal model of academic performance. Results are discussed and implications for the ECTS (European Credit Transfer System) are analyzed.

    2011-07-01

    Full Text Available Economic education in Romania has gone through many changes in recent years, in order to modernize and adapt to the requirements of the economy based on knowledge. But, regardless of the stage, students satisfaction is a key criterion for assessing the relevance and the accomplishment of the mission of universities in society. The highest satisfaction should be a constant concern for managers of higher education institutions. In order to achieve this goal, it is very important to periodically determine which are the most significant factors for students, how satisfied are they and which is the performance of the higher education for these attributes. The knowledge transfer process and the degree to which we can speak of a modern university tailored to the needs of the business environment and focused on increasing the relevance of the educational process for the labour market can be appreciated taking into consideration the content of the educational activities. The objective of this research is to identify relationships between the importance, satisfaction and performance of the instructional process in the process of improvement of the university management and the creation of better university programs. Our analysis was based on an empirical research conducted in a major Romanian faculty in the field: Faculty of Economics and Business Administration of Cluj-Napoca. The research was carried out by means of the survey method using quota sampling. Findings have revealed a significant positive contribution of the assessed factors to the increase of the quality of educational process. Also the factors that characterize the instructional process are correlated. The results revealed students concern to acquire practical knowledge. There is also a significant difference between students' expectations and students satisfaction regarding the quality of the content of teaching activity. Unfortunately, in case of all factors the performance of

  12. The effect of problem-based and lecture-based instructional strategies on learner problem solving performance, problem solving processes, and attitudes

    Science.gov (United States)

    Visser, Yusra Laila

    This study compared the effect of lecture-based instruction to that of problem-based instruction on learner performance (on near-transfer and far-transfer problems), problem solving processes (reasoning strategy usage and reasoning efficiency), and attitudes (overall motivation and learner confidence) in a Genetics course. The study also analyzed the effect of self-regulatory skills and prior-academic achievement on performance for both instructional strategies. Sixty 11th grade students at a public math and science academy were assigned to either a lecture-based instructional strategy or a problem-based instructional strategy. Both treatment groups received 18 weeks of Genetics instruction through the assigned instructional strategy. In terms of problem solving performance, results revealed that the lecture-based group performed significantly better on near-transfer post-test problems. The problem-based group performed significantly better on far-transfer post-test problems. In addition, results indicated the learners in the lecture-based instructional treatment were significantly more likely to employ data-driven reasoning in the solving of problems, whereas learners in the problem-based instructional treatment were significantly more likely to employ hypothesis-driven reasoning in problem solving. No significant differences in reasoning efficiency were uncovered between treatment groups. Preliminary analysis of the motivation data suggested that there were no significant differences in motivation between treatment groups. However, a post-research exploratory analysis suggests that overall motivation was significantly higher in the lecture-based instructional treatment than in the problem-based instructional treatment. Learner confidence was significantly higher in the lecture-based group than in the problem-based group. A significant positive correlation was detected between self-regulatory skills scores and problem solving performance scores in the problem

  14. Use of research-based instructional strategies in introductory physics: Where do faculty leave the innovation-decision process?

    Directory of Open Access Journals (Sweden)

    Charles Henderson

    2012-07-01

    Full Text Available During the fall of 2008 a web survey, designed to collect information about pedagogical knowledge and practices, was completed by a representative sample of 722 physics faculty across the United States (50.3% response rate. This paper presents partial results to describe how 20 potential predictor variables correlate with faculty knowledge about and use of research-based instructional strategies (RBIS. The innovation-decision process was conceived of in terms of four stages: knowledge versus no knowledge, trial versus no trial, continuation versus discontinuation, and high versus low use. The largest losses occur at the continuation stage, with approximately 1/3 of faculty discontinuing use of all RBIS after trying one or more of these strategies. Nine of the predictor variables were statistically significant for at least one of these stages when controlling for other variables. Knowledge and/or use of RBIS are significantly correlated with reading teaching-related journals, attending talks and workshops related to teaching, attending the physics and astronomy new faculty workshop, having an interest in using more RBIS, being female, being satisfied with meeting instructional goals, and having a permanent, full-time position. The types of variables that are significant at each stage vary substantially. These results suggest that common dissemination strategies are good at creating knowledge about RBIS and motivation to try a RBIS, but more work is needed to support faculty during implementation and continued use of RBIS. Also, contrary to common assumptions, faculty age, institutional type, and percentage of job related to teaching were not found to be barriers to knowledge or use at any stage. High research productivity and large class sizes were not found to be barriers to use of at least some RBIS.

  9. Using a profiling process to insure program quality: Volume I - a self-instructional manual

    Energy Technology Data Exchange (ETDEWEB)

    Kaser, J.S.; Roody, D.S.; Raizen, S.A.

    1996-11-01

    Between 1990 and 1995 the U.S. Department of Energy (DOE) and the National Center for Improving Science Education (National Center) developed a system for ongoing evaluation of K-12 educational programs in the DOE-supported national energy Laboratories. As part of the formative evaluation component of this collaborative endeavor, field staff in the Laboratories began creating profiles of their programs. However, many individuals within DOE Headquarters were not familiar with this profiling process and were unprepared to use the valuable information that the profiles generated. This manual was produced to orient Headquarters staff to profiling. It focuses on how Headquarters staff can use the profiling process to help their funded programs establish and/or maintain high quality. Its purpose, then, is not to train Headquarters staff to become proficient in profiling, but to show them how to draw on the Laboratories` use of profiling to bring about program improvement. Profiling is the process of systematically examining and describing a program`s elements against a set of components that define Effective Practice. The instrument used to capture the data for analysis is called a template, and most of this manual focuses on the templates and how to read and interpret them. However, since it is important to understand these data in context, the authors also describe what should accompany each template in a complete profiling packet and offer guidelines for reviewing complete packets and providing feedback to program managers.

    2014-10-01

    Full Text Available In the study reported here, we explored writing processes employed by 70 undergraduate learners of English as a Foreign Language (EFL through questionnaires and think-aloud protocols. Then we looked for possible differences in the writing processes employed by high- and low-aptitude learners. We observed that learners with higher aptitude scores devoted more attention to clausal complexity than those with lower levels of aptitude. Moreover, they resorted less frequently to their mother tongue while writing texts in English. High-aptitude EFL learners also used more global planning strategies than their low-aptitude peers and edited while writing much more frequently. Our review showed that even though aptitude has been extensively researched in second language acquisition and shown to correlate with the level of success in different skills, it has rarely been considered in relation to writing processes. We suggest that, as classroom teachers, EFL writing instructors accumulate and incorporate knowledge of their students’ aptitude in deploying their teaching strategies.

    Our study first determined what juveniles know about the juvenile court process. Second, it evaluated a DVD designed to be a systematic and simple way to improve this knowledge. A pre- and posttest design was used with two pilot samples and two samples from the population of interest. A sample from a juvenile detention center (n = 118) was the focus of this study. Initial knowledge of the court process was quite low for the detention sample (pretest M = 64.0%, SD = 14.2%). All samples experienced a significant improvement of knowledge after watching the DVD. Youth in the detention sample had a mean improvement from pretest to posttest of 6.4% (SD = 11.9%), with mean scores at posttest being 70.3% (SD = 17.4%). Respondents varied in their performance on different question topics, scoring the lowest on questions related to what happens at juvenile court hearings. The social and demographic variables of age, race, gender, grades in school, number of previous arrests, and the number of times the respondent had been to court were evaluated through regression analysis. Age and race were found to be significantly related to pretest scores, and race was significantly related to improvement scores.

    Faculty members in higher education are involved in many instructional design activities without formal training in learning theories and the science of instruction. Learning theories provide the foundation for the selection of instructional strategies and allow for reliable prediction of their effectiveness. To achieve effective learning outcomes, the science of instruction and instructional design models are used to guide the development of instructional design strategies that elicit appropriate cognitive processes. Here, the major learning theories are discussed and selected examples of instructional design models are explained. The main objective of this article is to present the science of learning and instruction as theoretical evidence for the design and delivery of instructional materials. In addition, this article provides a practical framework for implementing those theories in the classroom and laboratory. Copyright © 2016 The American Physiological Society.

    The purpose of this study was to investigate and compare the impact of Internet Virtual Physics Laboratory (IVPL) instruction with traditional laboratory instruction in physics academic achievement, performance of science process skills, and computer attitudes of tenth grade students. One-hundred and fifty students from four classes at one private senior high school in Taoyuan Country, Taiwan, R.O.C. were sampled. All four classes contained 75 students who were equally divided into an experimental group and a control group. The pre-test results indicated that the students' entry-level physics academic achievement, science process skills, and computer attitudes were equal for both groups. On the post-test, the experimental group achieved significantly higher mean scores in physics academic achievement and science process skills. There was no significant difference in computer attitudes between the groups. We concluded that the IVPL had potential to help tenth graders improve their physics academic achievement and science process skills.

    Weed, K; Ryan, E B

    1985-12-01

    The relationship between auditory and visual processing modality and strategy instructions was examined in first- and second-grade children. A Pictograph Sentence Memory Test was used to determine dominant processing modality as well as to assess instructional effects. The pictograph task was given first followed by auditory or visual interference. Children who were disrupted more by visual interference were classed as visual processors and those more disrupted by auditory interference were classed as auditory processors. Auditory and visual processors were then assigned to one of three conditions: interactive imagery strategy, sentence strategy, or a control group. Children in the imagery and sentence strategy groups were briefly taught to integrate the pictographs in order to remember them better. The sentence strategy was found to be effective for both auditory and visual processors, whereas the interactive imagery strategy was effective only for auditory processors.

A estratégia empresarial é uma área de significativa importância para os estudos administrativos, tendo em vista o impacto das decisões e ações estratégicas para o sucesso das empresas. Além disso, a teoria sobre estratégia está fortemente fundamentada em estudos realizados em empresas de grande porte, maduras, podendo, portanto, apresentar viés quando considerada a sua aplicação em empresas de pequeno porte e empresas em fase de desenvolvimento. Este estudo analisou os processos de criação de estratégias e propôs um conjunto de modelos representativos desses processos para pequenas empresas de base tecnológica criadas sem a formalização de planos de negócios, o que foi muito comum no início dos polos tecnológicos brasileiros na década de 80. Foi realizado um trabalho de campo cuja natureza foi a de pesquisa aplicada. O procedimento técnico utilizado foi o estudo multicasos, sendo investigadas cinco empresas de pequeno e uma de médio porte, conforme classificação pelo número de empregados, todas de base tecnológica e localizadas no Polo Tecnológico de São Carlos, em São Carlos, SP. O resultado da pesquisa evidenciou que as estratégias são criadas por etapas distintas, o que permitiu a construção de um conjunto de modelos representativos do processo de criação de estratégias, além de confirmar algumas hipóteses formuladas, podendo destacar que a ausência de formalização de planos de negócios não impediu o sucesso das empresas estudadas.The aim of this study was to analyze the strategic process and to propose a model that represents this process in small technology-based companies created without a business plan, which was very common in the beginning of a Brazilian Technopolis

It begins with a review of the history and evolution of instructional design and ends with a theoretical proposal. The objective of the article is to construct a critical proposal in response to the current debate over instructional design. The proposal places special emphasis on differences compared to the models that have served historically as the principal reference on this subject. To accomplish this, the term instruction is examined in depth, so as to arrive at a comprehensive approach to the globality of instructional design. The importance of identifying both the profile and the particular role of an instructional designer is emphasized as a way to establish a frame of reference for defining the practice of instructional design, the relationships constructed by institutional designers, and the interdisciplinary knowledge particular to their role.

    Full Text Available Learning quality constitutes one of the main challenges faced by Higher Education, thus a student centered teaching and the development of educational innovations that use active methodologies have been promoted. This article aims to evaluate the impact of using Just-in-Time Teaching and Peer Instruction on the results of teaching a subject, of disciplinary character, in 17 students of a career on an initial teacher training belonging to Chile’s Council of Rectors. A pre and postest model was applied between August and December 2012. The analysis used descriptive techniques that allowed the characterization of the admission profile and inferentials to explain, statistically, the observed differences in the performance of the subjects. In terms of perception, a positive assessment of the relationship between students and the teacher in the classroom was observed, this stood out above the improvement in the handling of disciplinary content.

  2. Cognitive processes among skilled miniature golf players: effects of instructions on motor performance, concentration time, and perceived difficulty.

    Science.gov (United States)

    Bäckman, L; Molander, B

    1991-01-01

    Highly skilled miniature golf players were examined on a simplified miniature golf task under different instructional conditions. Results indicated that requirements to attend to a variety of technical aspects of the game during preparation impaired motor performance, whereas providing players with those aspects of the game they reported thinking of did not affect motor performance. Data on concentration time and perceived difficulty indicated that increasing cognitive demands were associated with a decline in motor precision. The overall pattern of results was interpreted such that attention directed at technical aspects of the game interfered with the players' normal cognitive activity. Susceptibility to interference is a characteristic feature of controlled cognitive operations. Thus, the present results are consistent with the view that conscious cognitive activity may support motor behavior also at late stages of skill development.

  3. From Ideas to Opportunities: Exploring the Construction of Technology-Based Entrepreneurial Opportunities

    Directory of Open Access Journals (Sweden)

    Ferran Giones

    2013-06-01

    Full Text Available The transformation of business ideas into market opportunities is at the core of entrepreneurship. Nevertheless, the complexity of such a transformative process is seen to change depending on the variables influencing the opportunity-entrepreneur nexus. Although technology-entrepreneurship is regarded as a force of change and dynamism in socio-economic growth, it also depends upon an intricate process of opportunity development. The interest in understanding better how technology-based entrepreneurs simultaneously cope with technological uncertainty while trying to gain stakeholder support and access to resources, highlights a relevant research gap. The research described in this article uses the constructivist view to deepen our understanding of the technology-based entrepreneur’s conceptualization of the opportunity as a process of social construction. Our results show how initial consensus-building efforts and iteration with knowledgeable peers are an essential part of the emergence of the opportunity, changing both entrepreneur's and stakeholders' perceptions of the early business idea. Consequently, our results provide evidence in support of policy programs and measures that favour social-construction support mechanisms to foster technology-based entrepreneurship.

    Full Text Available This study implemented the proposed model of a constructivist teachinglearning process and determined the extent by which the students manifested the institutional learning outcomes which include competency, credibility, commitment and collaboration. It also investigated if there was an improvement in the learning outcomes after the implementation of the constructivist teachinglearning process and determined the students’ acceptance of the constructivist teaching-learning process. Towards the end a plan of action was proposed to enhance the students’ manifestation of the institutional learning outcomes. It made use of the qualitative- quantitative method particularly the descriptive design. The results of the study revealed that the students manifest competency, credibility, commitment and collaboration as they accept positively the constructivist teaching-learning process in their chemistry laboratory subject. It can be deduced from the findings that the constructivist teaching-learning process improved the learning outcomes of the students. The use of the proposed plan of action is recommended for an effective chemistry laboratory instruction.

  9. Realism vs. Constructivism in Contemporary Physics: The Impact of the Debate on the Understanding of Quantum Theory and its Instructional Process

    CERN Document Server

    Karakostas, Vassilios

    2009-01-01

    In the present study we attempt to incorporate the philosophical dialogue about physical reality into the instructional process of quantum mechanics. Taking into account that both scientific realism and constructivism represent, on the basis of a rather broad spectrum, prevalent philosophical currents in the domain of science education, the compatibility of their essential commitments is examined against the conceptual structure of quantum theory. It is argued in this respect that the objects of science do not simply constitute 'personal constructions' of the human mind for interpreting nature, as individualist constructivist consider, neither do they form products of a 'social construction', as sociological constructivist assume; on the contrary, they reflect objective structural aspects of the physical world. A realist interpretation of quantum mechanics, we suggest, is not only possible but also necessary for revealing the inner meaning of the theory's scientific content. It is pointed out, however, that a...

  14. Scaffolding in Assisted Instruction

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available On-The-Job Training, developed as direct instruction, is one of the earliest forms of training. This method is still widely in use today because it requires only a person who knows how to do the task, and the tools the person uses to do the task. This paper is intended to be a study of the methods used in education in Knowledge Society, with more specific aspects in training the trainers; as a result of this approach, it promotes scaffolding in assisted instruction as a reflection of the digital age for the learning process. Training the trainers in old environment with default techniques and designing the learning process in assisted instruction, as an application of the Vygotskian concept of the zone of proximal development (ZPD to the area of computer literacy for the younger users, generate diversity in educational communities and requires standards for technology infrastructure, standards for the content, developed as a concepts map, and applications for personalized in-struction, based on ZPD theory.

    2013-05-01

    The aim of nursing education is to prepare students with critical thinking, high interests in profession and high proficiency in patient care. Cooperative learning promotes team work and encourages knowledge building upon discussion. It has been viewed as one of the most powerful learning methods. Technology has been considered an influential tool in teaching and learning. It assists students in gathering more information to solve the problems and master skills better. The purpose of this study was to compare the effect of technology-based cooperative learning with technology-based individual learning in nursing students' critical thinking in catheterization knowledge gaining, error discovering, skill acquisitions, and overall scores. This study used a pretest-posttest experimental design. Ninety-eight students were assigned randomly to one of two groups. Questionnaires and tests were collected at baseline and after completion of intervention. The results of this study showed that there was no significant difference in related catheterization skill performance. However, the remaining variables differed greatly between the two groups. CONCLUSIONS AND APPLICATIONS: This study's findings guide the researchers and instructors to use technology-based cooperative learning more appropriately. Future research should address the design of the course module and the availability of mobile devices to reach student-centered and learn on the move goals. Copyright © 2011 Elsevier Ltd.

  1. Handling debugger breakpoints in a shared instruction system

    Science.gov (United States)

    Gooding, Thomas Michael; Shok, Richard Michael

    2014-01-21

    A debugger debugs processes that execute shared instructions so that a breakpoint set for one process will not cause a breakpoint to occur in the other processes. A breakpoint is set by recording the original instruction at the desired location and writing a trap instruction to the shared instructions at that location. When a process encounters the breakpoint, the process passes control to the debugger for breakpoint processing if the breakpoint was set at that location for that process. If the trap was not set at that location for that process, the cacheline containing the trap is copied to a small scratchpad memory, and the virtual memory mappings are changed to translate the virtual address of the cacheline to the scratchpad. The original instruction is then written to replace the trap instruction in the scratchpad, so that process can execute the instructions in the scatchpad thereby avoiding the trap instruction.

  2. Innovative cold joining technologies based on tube forming

    Alves Luis M.

    2015-01-01

    Full Text Available This paper is focused on innovative cold joining technologies for connecting tubes and fixing tubes to sheets. The proposed technologies are based on the utilization of plastic instability waves in thin-walled tubes subjected to axial compression and may be seen as an alternative to conventional joining technologies based on mechanical fixing with fasteners, welding and structural adhesive bonding. Besides allowing connecting dissimilar materials and being successfully employed in fixture conditions that are difficult and costly to achieve by means of conventional joining the new proposed technologies also cope with the growing concerns on the demand, lifecycle and recycling of materials.

    2015-07-01

    This study examined the extent to which a computer-based social skills intervention called FaceSay was associated with improvements in affect recognition, mentalizing, and social skills of school-aged children with Autism Spectrum Disorder (ASD). FaceSay offers students simulated practice with eye gaze, joint attention, and facial recognition skills. This randomized control trial included school-aged children meeting educational criteria for autism (N = 31). Results demonstrated that participants who received the intervention improved their affect recognition and mentalizing skills, as well as their social skills. These findings suggest that, by targeting face-processing skills, computer-based interventions may produce changes in broader cognitive and social-skills domains in a cost- and time-efficient manner.

    2007-05-01

    In this article we examine how (i) company type and (ii) the competitive intelligence information used by small technology-based companies affect their innovation performance. The focus is on the specific information types used and not on the information sources. Information topics are classified in four groups - customers (10), company (9), competitor (11) and industry (12). The sample consists of 45 small new technology-based companies, specialized suppliers, and service companies from a variety of sectors - software, photonics, telecommunications, biomedical engineering and biotech, traditional manufacturing etc. The results suggest that the total number of intelligence information topics companies use to make decisions about innovation is not associated with the number of their new products, processes, services and patents. Therefore the companies in our sample do not seem to have the resources, processes or value systems required to use different competitive intelligence information when making decisions on innovation or may rely more on their own internal logic than on external information. Companies are classified using a Pavitt-like taxonomy. Service companies are considered as a separate company type. This allows for explicitly studying both, the innovative role of new services in product driven companies, and the role of new product development in service companies.

    Modern Radiography technology was combined with radiation physics and modern imaging processing, which was an important branch of information obtainment and processing. We can get the inside information of the object, by the X ray's attenuation when the ray penetrated the object, and depending on the computer's fast processing, we can see the slice imaging of the object. Computerized Tomography, Computerized Laminography, and Digital Radiography were important parts in Radiography. The institute of applied electronics, CAEP in the research of intense radiation had developed several advanced radiation sources and some advanced radiography imaging systems, for example, S-band small spot linear accelerator, full solid state modulator, C-band linear accelerator, high energy Tera-hertz radiation source and CT technology based on cone beam, DR technology, CL Technology etc. Such imaging systems had been applied in industrial NDT/NDE, security check, medical diagnosis, petroleum and gas pipeline inspection system etc.

    Han, Song-I; Han, Ki-Ho

    2013-01-01

    As lab-on-a-chips are developed for on-chip integrated microfluidic systems with multiple functions, the development of microfluidic interface (MFI) technology to enable integration of complex microfluidic systems becomes increasingly important and faces many technical difficulties. Such difficulties include the need for more complex structures, the possibility of biological or chemical cross-contamination between functional compartments, and the possible need for individual compartments fabricated from different substrate materials. This chapter introduces MFI technology, based on rapid stereolithography, for a glass-based miniaturized genetic sample preparation system, as an example of a complex lab-on-a-chip that could include functional elements such as; solid-phase DNA extraction, polymerase chain reaction, and capillary electrophoresis. To enable the integration of a complex lab-on-a-chip system in a single chip, MFI technology based on stereolithography provides a simple method for realizing complex arrangements of one-step plug-in microfluidic interconnects, integrated microvalves for microfluidic control, and optical windows for on-chip optical processes.

    ZHAO Min; QIU Zongming; QU Jiamin; LIU Hongzhao

    2008-01-01

    A new method of guideless spatial coordinate measurement technology based on coding pole and vision measurement is proposed. Unequal spacing of bar code is adopted to pole, so that the code combination of pole image in measuring field is unique. Holographic characteristics of numeric coding pole are adopted to obtain pole pose and pole probe position by any section of bar code on the pole. Spatial coordinates of measuring points can be obtained by coordinate transform. The contradiction between high resolution and large visual field of image sensor is resolved, thereby providing a new concept for surface shape measurement of large objects with high precision. The measurement principles of the system are expounded and mathematic model is established. The measurement equation is evaluated by simulation experiments and the measurement precision is analyzed. Theoretical analysis and simulation experiments prove that this system is characterized by simple structure and wide measurement range. Therefore it can be used in the 3-dimentional coordinate measurement of large objects.

    2011-02-15

    The reliability analysis of new technology-based transmitters has to deal with specific issues: various interactions between both material elements and functions, undefined behaviours under faulty conditions, several transmitted data, and little reliability feedback. To handle these particularities, a '3-step' model is proposed, based on goal tree-success tree (GTST) approaches to represent both the functional and material aspects, and includes the faults and failures as a third part for supporting reliability analyses. The behavioural aspects are provided by relationship matrices, also denoted master logic diagrams (MLD), with stochastic values which represent direct relationships between system elements. Relationship analyses are then proposed to assess the effect of any fault or failure on any material element or function. Taking these relationships into account, the probabilities of malfunction and failure modes are evaluated according to time. Furthermore, uncertainty analyses tend to show that even if the input data and system behaviour are not well known, these previous results can be obtained in a relatively precise way. An illustration is provided by a case study on an infrared gas transmitter. These properties make the proposed model and corresponding reliability analyses especially suitable for intelligent transmitters (or 'smart sensors').

    Huffman, Scott B.; Laird, John E.

    1994-01-01

    Despite its ubiquity in human learning, very little work has been done in artificial intelligence on agents that learn from interactive natural language instructions. In this paper, the problem of learning procedures from interactive, situated instruction is examined in which the student is attempting to perform tasks within the instructional domain, and asks for instruction when it is needed. Presented is Instructo-Soar, a system that behaves and learns in response to interactive natural language instructions. Instructo-Soar learns completely new procedures from sequences of instruction, and also learns how to extend its knowledge of previously known procedures to new situations. These learning tasks require both inductive and analytic learning. Instructo-Soar exhibits a multiple execution learning process in which initial learning has a rote, episodic flavor, and later executions allow the initially learned knowledge to be generalized properly.

    The USAID has, since 1972, funded the development of a new methodology for educational radio for young children through 3 projects: the Radio Mathematics PRoject of Nicaragua, the Radio Language Arts Project of Kenya, and the Radio Science PRoject of Papua New Guinea. These projects developed math programs for grades 1-4 and English as a second language for grades 1-3; programs to teach science in grades 4-6 are now being developed. Appropriate techniques were developed to engage young children actively in the learning process. Lessons are planned as a "conversation" between the children and the radio; scripts are written as 1/2 of a dialogue, with pauses carefully timed so that written as 12 of a dialogue, with pauses carefully timed so that students can contribute their 1/2. Teaching techniques used in all 3 projects include choral responses, simultaneous individual seatwork, and activities using simple materials such as pebbles and rulers. Certain techniques were specific to the subject being taught, or to the circumstances in which the lessons were to be used. Patterned oral drill was used frequently in the English lessons, including sound-cued drills. "Deferred" oral responses were used often in the math lessons. In this method, the children are instructed to solve a problem silently, not giving the answer aloud until requested, thus allowing time for even the slower children to participate. "One-child" questions were used in both English and science: the radio asks a question to be answered by a single child, who is selected on the spot by the classroom teacher. This allows for open-ended questions, but also requires constant supervision of the classroom teacher. Songs and games were used in all programs, and extensively for didactic purposes in the teaching of English. Instructions for science activities are often more complex than in other courses, particularly when the children are using science apparatus, especially when they work in pairs to share scarce

  3. Instructive selection and immunological theory.

    The turning point of modern immunological theory was the advent of the clonal selection theory (Burnet, Talmage - 1957). A useful heuristic in the classification of theoretical models was the contrast of 'instructive' with 'selective' models of the acquisition of information by biological systems. The neo-Darwinian synthesis of the 1940s had consolidated biologists' model of evolution based on prior random variation and natural selection, viz. differential fecundity. While evolution in the large was by then pretty well settled, controversy remained about examples of cellular adaptation to chemical challenges, like induced drug-resistance, enzyme formation and the antibody response. While instructive theories have been on the decline, some clear cut examples can be found of molecular imprinting in the abiotic world, leading, e.g. to the production of specific sorbents. Template-driven assembly, as in DNA synthesis, has remained a paradigm of instructive specification. Nevertheless, the classification may break down with more microscopic scrutiny of the processes of molecular fit of substrates with enzymes, of monomers to an elongating polymer chain, as the reactants often traverse a state space from with activated components are appropriately selected. The same process may be 'instructive' from a holistic, 'selective' from an atomic perspective.

    Clifford, Matthew Aaron

    Local instructional design describes the process of customization that naturally occurs when curriculum innovations interface with local classrooms and schools. Describing the practice of local instructional design can help to explain how curriculum is adapted to local conditions and provides insight on how instructional leaders mediate curriculum, teaching, and school conditions to allow for reform-oriented curriculum to occur. Research on local design has tended to focus on the intersection of curriculum, teachers, and students. This case-based dissertation study documents the process of local instructional design in the context of high school science education through a distributed leadership perspective. The study develops a model of instructional design, points to the important roles of administrators, parents, and university consultants in leading local design, and suggests instructional reform advocates consider the role of school leadership and community when further studying local instructional design.

    At the present time, nearly all Dutch nursing schools are searching for suitable ways to implement technology-based healthcare in their curriculum. Some Universities chose elective education, others a mandatory solution. Several studies were executed to determine competencies needed by nurses in order to work with technology-based healthcare. In 2016 a nationwide new curriculum for nurses has been published. Providing technology-based healthcare is included under the core competencies of this new curriculum. All baccalaureate nursing educational institutes must implement this new curriculum at the start of 2016 which will have a huge impact on the implementation of technology-based healthcare in the education programs. In the future, technology centers from Universities will collaborate and specialize, partner with technology companies and crossovers between information and communication technology and healthcare education will be expanded.

    Full Text Available Introduction: Technology-based interventions offer an opportunity to address high-risk behaviors in the emergency department (ED. Prior studies suggest behavioral health strategies are more effective when gender differences are considered. However, the role of gender in ED patient preferences for technology-based interventions has not been examined. The objective was to assess whether patient preferences for technology-based interventions varies by gender. Methods: This was a secondary analysis of data from a systematic survey of adult (18 years of age, English-speaking patients in a large urban academic ED. Subjects were randomly selected during a purposive sample of shifts. The iPad survey included questions on access to technology, preferences for receiving health information, and demographics. We defined ‘‘technology-based’’ as web, text message, e-mail, social networking, or DVD; ‘‘non-technology-based’’ was defined as in-person, written materials, or landline. We calculated descriptive statistics and used univariate tests to compare men and women. Gender-stratified multivariable logistic regression models were used to examine associations between other demographic factors (age, race, ethnicity, income and technology-based preferences for information on specific risky behaviors. Results: Of 417 participants, 45.1% were male. There were no significant demographic differences between men and women. Women were more likely to use computers (90.8% versus 81.9%; p¼0.03, Internet (66.8% versus 59.0%; p¼0.03, and social networks (53.3% versus 42.6%; p¼0.01. 89% of men and 90% of women preferred technology-based formats for at least type of health information; interest in technology-based for individual health topics did not vary by gender. Concern about confidentiality was the most common barrier to technology-based use for both genders. Multivariate analysis showed that for smoking, depression, drug/alcohol use, and injury

    2016-10-27

    In the past 10 years, mental and behavioral health has seen a proliferation of technology-based interventions in the form of online and other computer-delivered programs. This paper focuses on technology-based treatment and preventive interventions aimed at benefitting children and adolescents via either involving the parents and families, or only the youth. The review considered only technology-based interventions that had at least one published study with a randomized controlled trial design. Questions being addressed included: (1) What are the technology-based interventions in the mental/behavioral health area that have been systematically evaluated in published studies? (2) What are the common and unique characteristics of these interventions and their application with respect to sample characteristics, target problems, and technology characteristics (platforms, structures, elements, and communication formats)? and (3) Which intervention approaches and strategies have accrued the greatest evidence? The review identified 30 technology-based psychosocial interventions for children and families, 19 of which were parent or family-focused (32 studies) and 11 of which were youth-focused (in 13 studies). For the parent/family-focused interventions, greatest promise was found in those that addressed either youth behavioral problems or depressive/anxious symptoms, as well as more general bolstering of parenting efficacy. The youth-focused interventions showed some promise in reducing depressive/anxious symptoms. Advantages and disadvantages of the technology-based approaches were considered, and areas for future research and development were discussed.

  19. Evaluation of a Theory of Instructional Sequences for Physics Instruction

    Wackermann, Rainer; Trendel, Georg; Fischer, Hans E.

    2010-05-01

    The background of the study is the theory of basis models of teaching and learning, a comprehensive set of models of learning processes which includes, for example, learning through experience and problem-solving. The combined use of different models of learning processes has not been fully investigated and it is frequently not clear under what circumstances a particular model should be used by teachers. In contrast, the theory under investigation here gives guidelines for choosing a particular model and provides instructional sequences for each model. The aim is to investigate the implementation of the theory applied to physics instruction and to show if possible effects for the students may be attributed to the use of the theory. Therefore, a theory-oriented education programme for 18 physics teachers was developed and implemented in the 2005/06 school year. The main features of the intervention consisted of coaching physics lessons and video analysis according to the theory. The study follows a pre-treatment-post design with non-equivalent control group. Findings of repeated-measures ANOVAs show large effects for teachers' subjective beliefs, large effects for classroom actions, and small to medium effects for student outcomes such as perceived instructional quality and student emotions. The teachers/classes that applied the theory especially well according to video analysis showed the larger effects. The results showed that differentiating between different models of learning processes improves physics instruction. Effects can be followed through to student outcomes. The education programme effect was clearer for classroom actions and students' outcomes than for teachers' beliefs.

    Network-based manufacturing is a kind of distributed system, which enables manufacturers to finish production tasks as well as to grasp the opportunities in the market, even if manufacturing resources are insufficient. One of the main problems in network-based manufacturing is the allocation of resources and the assignment of tasks rationally, according to flexible resource distribution. The mapping rules and relations between production techniques and resources are proposed, followed by the definition of the resource unit. Ultimately, the genetic programming method for the optimization of the manufacturing system is put forward. A set of software for the optimization system of simulation process using genetic programming techniques has been developed, and the problems of manufacturing resource planning in network-based manufacturing are solved with the simulation of optimizing methods by genetic programming. The optimum proposal of hardware planning, selection of company and scheduling will be obtained in theory to help company managers in scientific decision-making.

Stereolithography (SLA) as a mature 3D printing technology has been widely applied in industrial manufacture. SLA is the process of single-photon polymerization (SPP), and its resolution is controlled by the optical diffraction limit, which cannot meet the requirement for three dimensional micro/nanostructures with high resolution. Unlike SLA, 3D printing technology based on two-photon polymerization (TPP) induced by a near-infrared femtosecond laser can fabricate arbitrary and ultraprecise 3D microstructures with high resolution not only on the microscopic scale but also on the nanoscale. In this review, the principles of two-photon absorption and TPP were concisely explained. The development of TPP mainly focusing on TPP resolution and TPP initiators were introduced as well as the applications of 3D printing technology based on TPP. Finally, the perspective of 3D printing technology based on TPP was proposed.

    This study was designed to measure some effects of supplemental instruction in chemistry. Supplemental instruction is a peer-led cooperative learning program that encourages students to develop conceptual understanding by articulating both understandings and misconceptions in a think-aloud fashion. Supplemental instruction was offered three hours weekly outside of class and lab time for students in four classes of General Organic and Biological Chemistry. Over a two-year period 108 students volunteered to participate in this program; 45 students did not participate. As measured by final grades in chemistry and responses to a questionnaire, supplemental instruction was effective in increasing students' achievement in chemistry. Further research is needed to determine the in-depth effects of supplemental instruction on students' learning, problem solving, and self-esteem.

    Emergent technologies often suffer from a lack of an installed manufacturing base and an obvious dominant manufacturing technique. Firms which base their search for competitive advantage on emergent disruptive technologies must make hard production choices and endure major manufacturing discontinuities. The authors as well as many other firms, are now facing these challenges with the embrace of microsystems technologies. They add to the literature by providing a set of criteria for firms investing in emergent disruptive technologies. Sandia has long been associated as a pioneer in the development of new manufacturing techniques. Microsystems is just the current in a long line of manufacturing technologies that have been considered for mission critical system applications. The authors as well as others, have had to make the hard choice of investing in specific microsystems manufacturing techniques. Important considerations in the technique choice include: the existing internal manufacturing bases, commonality with existing commercial manufacturing infrastructure, current and projected critical performance characteristics, learning curves, the promise to add new but un-thought-of functionally to existing systems, and the anticipated ability to qualify devices built from the technique for mission critical applications.

    Ueda, Haruka; Dazai, Ryota; Kaseda, Chosei; Ikaga, Toshiharu; Kato, Akihiro

    Demand among large office buildings for the energy-saving benefits of the HVAC (Heating, Ventilating and Air-Conditioning) System are increasing as more and more people become concerned with global environmental issues. However, immoderate measures taken in the interest of energy conservation may encroach on the thermal comfort and productivity level of office workers. Building management should satisfy both indoor thermal comfort and energy conservation while adapting to the many regulatory, social, climate, and other changes that occur during the lifespan of the building. This paper demonstrates how optimal control of the HVAC system, based on data modeling and the multi-objective optimal method, achieves an efficient equilibrium between thermal comfort and energy conservation.

DR, DG, DB values of trace color are obtained by color sensor, with which hue value denoting trace color characteristic can be calculated. Combined with graph theory algorithm, hue value can be used as a parameter for tracking deviation and branch identification to implement shortest path tracking. In addition, considering discreteness and uncertainty of single sensor in detecting trace information, sensor array is adopted for information fusion to achieve accurate tracking. Compared to tracking trace by single intensity sensor, AGV tracking based on RGB color sensor array has much better trace tracking and branch identification performances on complex roads.

    Accurate and fast detection of infrared (IR) dim target has very important meaning for infrared precise guidance, early warning, video surveillance, etc. In this paper, some basic principles and the implementing flow charts of a series of algorithms for target detection are described. These algorithms are traditional two-frame difference method, improved three-frame difference method, background estimate and frame difference fusion method, and building background with neighborhood mean method. On the foundation of above works, an infrared target detection software platform which is developed by OpenCV and MFC is introduced. Three kinds of tracking algorithms are integrated in this software. In order to explain the software clearly, the framework and the function are described in this paper. At last, the experiments are performed for some real-life IR images. The whole algorithm implementing processes and results are analyzed, and those algorithms for detection targets are evaluated from the two aspects of subjective and objective. The results prove that the proposed method has satisfying detection effectiveness and robustness. Meanwhile, it has high detection efficiency and can be used for real-time detection.

    In FY-2000, Engineering at Lawrence Livermore National Laboratory faced significant pressures to meet critical project milestones, and immediate demands to facilitate the reassignment of employees as the National Ignition Facility (the 600-TW laser facility being designed and built at Livermore, and one of the largest R&D construction projects in the world) was in the process of re-baselining its plan while executing full-speed its technology development efforts. This drive for change occurred as an unprecedented level of management and program changes were occurring within LLNL. I am pleased to report that we met many key milestones and achieved numerous technological breakthroughs. This report summarizes our efforts to perform feasibility and reduce-to-practice studies, demonstrations, and/or techniques--as structured through our technology centers. Whether using computational engineering to predict how giant structures like suspension bridges will respond to massive earthquakes or devising a suitcase-sized microtool to detect chemical and biological agents used by terrorists, we have made solid technical progress. Five Centers focus and guide longer-term investments within Engineering, as well as impact all of LLNL. Each Center is responsible for the vitality and growth of the core technologies it represents. My goal is that each Center will be recognized on an international scale for solving compelling national problems requiring breakthrough innovation. The Centers and their leaders are as follows: Center for Complex Distributed Systems--David B. McCallen; Center for Computational Engineering--Kyran D. Mish; Center for Microtechnology--Raymond P. Mariella, Jr.; Center for Nondestructive Characterization--Harry E. Martz, Jr.; and Center for Precision Engineering--Keith Carlisle.

    A picture can be a powerful communication tool. However, creating pictures to illustrate patient instructions can be a costly and time-consuming task. Building on our prior research in this area, we developed a computer application that automatically converts text to pictures using natural language processing and computer graphics techniques. After iterative testing, the automated illustration system was evaluated using 49 previously unseen cardiology discharge instructions. The completeness of the system-generated illustrations was assessed by three raters using a three-level scale. The average inter-rater agreement for text correctly represented in the pictograph was about 66 percent. Since illustration in this context is intended to enhance rather than replace text, these results support the feasibility of conducting automated illustration.

    Full Text Available In today’s economy, innovation is considered to be one of the main driving forces behind business competitiveness, if not the most relevant one. Traditionally, the study of innovation has been addressed from different perspectives. Recently, literature on knowledge management and intellectual capital has provided new insights. Considering this, the aim of this paper is to analyze the impact of different organizational conditions – i.e. “structural capital” – on innovation capability and innovation performance, from an “intellectual capital” (IC perspective. As regards innovation capability, two dimensions are considered: new idea generation and innovation project management. The population subject to study is made up of technology-based Colombian firms. In order to gather information about the relevant variables involved in the research, a questionnaire was designed and addressed to the CEOs of the companies making up the target population. The sample analyzed is made up of 69 companies and is large enough to carry out a statistical study based on structural equation modelling (partial least squares approach using PLS-Graph software (Chin and Frye, 2003. The results obtained show that structural capital explains to a great extent both the effectiveness of the new idea generation process and of innovation project management. However, the influence of each specific organizational component making up structural capital (organizational design, organizational culture, hiring and professional development policies, innovation strategy, technological capital, and external structure varies. Moreover, successful innovation project management is the only innovation capability dimension that exerts a significant impact on company performance.

  17. Why simulation can be efficient: on the preconditions of efficient learning in complex technology based practices

    2009-07-01

    Full Text Available Abstract Background It is important to demonstrate learning outcomes of simulation in technology based practices, such as in advanced health care. Although many studies show skills improvement and self-reported change to practice, there are few studies demonstrating patient outcome and societal efficiency. The objective of the study is to investigate if and why simulation can be effective and efficient in a hi-tech health care setting. This is important in order to decide whether and how to design simulation scenarios and outcome studies. Methods Core theoretical insights in Science and Technology Studies (STS are applied to analyze the field of simulation in hi-tech health care education. In particular, a process-oriented framework where technology is characterized by its devices, methods and its organizational setting is applied. Results The analysis shows how advanced simulation can address core characteristics of technology beyond the knowledge of technology's functions. Simulation's ability to address skilful device handling as well as purposive aspects of technology provides a potential for effective and efficient learning. However, as technology is also constituted by organizational aspects, such as technology status, disease status, and resource constraints, the success of simulation depends on whether these aspects can be integrated in the simulation setting as well. This represents a challenge for future development of simulation and for demonstrating its effectiveness and efficiency. Conclusion Assessing the outcome of simulation in education in hi-tech health care settings is worthwhile if core characteristics of medical technology are addressed. This challenges the traditional technical versus non-technical divide in simulation, as organizational aspects appear to be part of technology's core characteristics.

  8. The Impact of Revised Discharge Instructions on Patient Satisfaction

    Directory of Open Access Journals (Sweden)

    Heather Markey Waniga RN, MSN

    2016-09-01

    Full Text Available Introduction: The impact of discharge instructions on a patient’s experience is not fully understood. This research explored whether nurse- and physician-generated discharge instructions had a positive effect on patient perceptions regarding their discharge experience. Methods: We compared Press Ganey discharge-related patient satisfaction scores for the year prior to and the year subsequent to implementing revised discharge instructions for all patients admitted to a 180-bed community-based hospital. Results: Following the implementation of our revised discharge instructions, patient satisfaction significantly improved (84.7% vs 83%, P < .01. Patients responded that they felt ready for discharge (86.6% vs 84.9%, P = .01 and were satisfied with instructions for home care (87.8% vs 85.3%, P < .01. Discussion: This study finds that a novel discharge instruction set produced by both the nursing and physician staff may improve patient perceptions with the discharge process.

  10. A new look at comprehension instruction for disabled readers.

    Science.gov (United States)

    Maria, K

    1987-01-01

    The traditional specific skills approach to comprehension instruction is no longer considered useful since research has demonstrated that comprehension is a holistic process. However, one must break down the process in some way in order to teach it. Three models of comprehension instruction that attempt to break down the process are described. Strengths and weaknesses of each of the three models: text-based instruction, explicit comprehension instruction, and a combined model, are discussed. Techniques which are exemplars of each of the models are described in relation to their use with reading-disabled children. The combined model of comprehension instruction is recommended because it joins the goal of understanding the text with helping children learn how to learn.

    Ranney, Megan L; Choo, Esther K; Spirito, Anthony; Mello, Michael J

    2013-04-01

    This study aimed to (1) determine the prevalence of technology use and interest in technology-based interventions among adolescent emergency department patients and (2) examine the association between interest in an intervention and self-reported risky behaviors. Adolescents (age, 13-17 years) presenting to an urban pediatric emergency department completed a survey regarding baseline technology use, risky behaviors, and interest in and preferred format for behavioral health interventions. Questions were drawn from validated measures when possible. Descriptive statistics and χ2 tests were calculated to identify whether self-reported risky behaviors were differentially associated with intervention preference. Two hundred thirty-four patients (81.8% of eligible) consented to participate. Almost all used technology, including computers (98.7%), social networking (84.9%), and text messaging (95.1%). Adolescents reported high prevalence of risky behaviors as follows: unintentional injury (93.2%), peer violence exposure (29.3%), dating violence victimization (23.0%), depression or anxiety (30.0%), alcohol use (22.8%), drug use (36.1%), cigarette use (16.4%), and risky sexual behaviors (15.1%). Most were interested in receiving behavioral interventions (ranging from 93.6% interest in unintentional injury prevention, to 73.1% in smoking cessation); 45% to 93% preferred technology-based (vs in person, telephone call, or paper) interventions for each topic. Proportion interested in a specific topic and proportion preferring a technology-based intervention did not significantly differ by self-reported risky behaviors. Among this sample of adolescent emergency department patients, high rates of multiple risky behaviors are reported. Patients endorsed interest in receiving interventions for these behaviors, regardless of whether they reported the behavior. Most used multiple forms of technology, and approximately 50% preferred a technology-based intervention format.

    The prevalence of obesity increases worldwide. The use of technology-based interventions can be beneficial in weight loss interventions. This review aims to provide insight in the effectiveness of technology-based interventions on weight loss and quality of life for patients suffering overweight or obesity compared to standard care. Pubmed, PsycInfo, Web of Science, ScienceDirect, CINAHL and Embase were searched from the earliest date (of each database) up to February 2015. Interventions needed to be aimed at reducing or maintaining weight loss in persons with a body mass index (BMI) ≥ 25 kg/m(2) and have a technology aspect. Cochrane Collaboration's tool for assessing risk of bias was used for rating the methodological quality. Twenty-seven trials met inclusion criteria. Thirteen studies showed significant effects on weight loss compared to controls. Most interventions used a web-based approach (42%). Interventions were screened for five technical key components: self-monitoring, counsellor feedback and communication, group support, use of a structured program and use of an individually tailored program. All interventions that used a combination of all five or four components showed significant decreases in weight compared to controls. No significant results for quality of life were found. Outcomes on program adherence were reported in six studies. No significant results were found between weight loss and program adherence. Evidence is lacking about the optimal use of technology in weight loss interventions. However, when the optimal combination of technological components is found, technology-based interventions may be a valid tool for weight loss. Furthermore, more outcomes on quality of life and information about the effect of technology-based intervention after bariatric surgery are needed.

  17. Technology-based self-care methods of improving antiretroviral adherence: a systematic review.

    Directory of Open Access Journals (Sweden)

    Parya Saberi

    Full Text Available As HIV infection has shifted to a chronic condition, self-care practices have emerged as an important topic for HIV-positive individuals in maintaining an optimal level of health. Self-care refers to activities that patients undertake to maintain and improve health, such as strategies to achieve and maintain high levels of antiretroviral adherence.Technology-based methods are increasingly used to enhance antiretroviral adherence; therefore, we systematically reviewed the literature to examine technology-based self-care methods that HIV-positive individuals utilize to improve adherence. Seven electronic databases were searched from 1/1/1980 through 12/31/2010. We included quantitative and qualitative studies. Among quantitative studies, the primary outcomes included ARV adherence, viral load, and CD4+ cell count and secondary outcomes consisted of quality of life, adverse effects, and feasibility/acceptability data. For qualitative/descriptive studies, interview themes, reports of use, and perceptions of use were summarized. Thirty-six publications were included (24 quantitative and 12 qualitative/descriptive. Studies with exclusive utilization of medication reminder devices demonstrated less evidence of enhancing adherence in comparison to multi-component methods.This systematic review offers support for self-care technology-based approaches that may result in improved antiretroviral adherence. There was a clear pattern of results that favored individually-tailored, multi-function technologies, which allowed for periodic communication with health care providers rather than sole reliance on electronic reminder devices.

    Mental models are one way that humans represent knowledge (Markman, 1999). Instructional design (ID) is a conceptual model for developing instruction and typically includes analysis, design, development, implementation, and evaluation (i.e., ADDIE model). ID, however, has been viewed differently by practicing teachers and instructional designers…

  3. Instructional decision making of high school science teachers

    Carver, Jeffrey S.

    The instructional decision-making processes of high school science teachers have not been well established in the literature. Several models for decision-making do exist in other teaching disciplines, business, computer game programming, nursing, and some fields of science. A model that incorporates differences in science teaching that is consistent with constructivist theory as opposed to conventional science teaching is useful in the current climate of standards-based instruction that includes an inquiry-based approach to teaching science. This study focuses on three aspects of the decision-making process. First, it defines what factors, both internal and external, influence high school science teacher decision-making. Second, those factors are analyzed further to determine what instructional decision-making processes are articulated or demonstrated by the participants. Third, by analyzing the types of decisions that are made in the classroom, the classroom learning environments established as a result of those instructional decisions are studied for similarities and differences between conventional and constructivist models. While the decision-making process for each of these teachers was not clearly articulated by the teachers themselves, the patterns that establish the process were clearly exhibited by the teachers. It was also clear that the classroom learning environments that were established were, at least in part, established as a result of the instructional decisions that were made in planning and implementation of instruction. Patterns of instructional decision-making were different for each teacher as a result of primary instructional goals that were different for each teacher. There were similarities between teachers who exhibited more constructivist epistemological tendencies as well as similarities between teachers who exhibited a more conventional epistemology. While the decisions that will result from these two camps may be different, the six step

    Schmidt, Ronald G.

    Wright State University, Dayton, Ohio, is preparing for its third cycle of the Interactive Remote Instructional System (IRIS) in groundwater hydrology, beginning January 15, 1986. The first cycle finished with an impressive completion ratio for registered participants, and the second cycle has currently been underway since July. This comprehensive hydrogeology program was originally developed for the Soil Conservation Service (of the U.S. Department of Agriculture) to prepare their personnel for professional practice work. Since its evolution into IRIS, an 80% participant completion rate has been recorded for the first cycle, which is a significant departure from success rates traditionally recorded by correspondence courses. This excellent rate of success is the result of 2 years of refinement and demonstrates the progressive nature of the program. IRIS has met the needs of participants by developing a curriculum that reflects current trends in the groundwater industry and has provided a unique educational approach that ensures maximum interaction between the instructional staff and participants.

    Instructor immediacy has been positively associated with many desirable academic outcomes including increased student learning. This study extends existing understanding of instructional immediacy behaviours in elearning by describing postgraduate nursing students' reflections on their own experience. An exploratory, descriptive survey design was used to collect qualitative data. Participants were asked what behaviours or activities help to create rapport or a positive interpersonal connection (immediacy) between students and their online teacher(s). Thematic analysis of the data revealed three main themes: acknowledging and affirming student's personal and professional responsibilities; providing clear and timely information; and utilising rich media. These findings give lecturers insight into instructional strategies they may adopt to increase immediacy in elearning and hence improve student learning outcomes.

    Full Text Available The reason why the Trayvon Martin murder trial and similar court cases create a philosophical rift in our nation is due in part to flaws in the delivery of multicultural education. Traditional multicultural instruction does not prepare citizens for the subtleties and complexities of race relations. This study investigates critical strategies and practices that address multicultural missing gaps. I also seek to fill a void in the literature created by a lack of student input regarding teaching strategies that encourage lifelong learning. Students (N = 337 enrolled at a Midwestern university were asked to rate the efficacy of selected instructional strategies. Utilizing a 9-point Likert-type scale, students gave themselves a personal growth rating of 7.15 (SD = 1.47. Variables important to predicting that growth (R2 = .56, p < .0005 were a six-factor variable known as a non-color-blind instructional approach (t = 10.509, p ≤ .0005, allowing students an opportunity to form their own opinions apart from the instructor (t = 4.797, p ≤ .0005, and a state law that mandated multicultural training (t = 3.234, p = .001. Results demonstrated that utilizing a 35% traditional and 65% critical pedagogy mixture when teaching multicultural education helped promote win/win scenarios for education candidates hoping to become difference makers.

    Full Text Available Business incubators are a great source of encouragement for innovative projects, enabling the development of new technologies, providing infrastructure, advice and support, which are key elements for the success of new business. The technology-based firm incubators (TBFs, which are 154 in Brazil. Each one of them has its own mechanism for the selection of the incubation companies. Because of the different forms of management of incubators, the business model CERNE - Reference Center for Support for New Projects - was created by Anprotec and Sebrae, in order to standardize procedures and promote the increase of chances for success in the incubations. The objective of this study is to propose selection criteria for the incubation, considering CERNE’s five dimensions and aiming to help on the decision-making in the assessment of candidate companies in a TBF incubator. The research was conducted from the public notices of 20 TBF incubators, where 38 selection criteria were identified and classified. Managers of TBF incubators validated 26 criteria by its importance via online questionnaires. As a result, favorable ratings were obtained to 25 of them. Only one criterion differed from the others, with a unfavorable rating.

    Full Text Available The purpose of this study is to contribute to a better understanding of the strategic and organisational con gurations that companies can use to generate value with product-market systems and their busi- ness models that have been dominant in the past but forced back into niche positions by innovation. The former dominant music format vinyl was rapidly substituted after the introduction of digital music. However, still nowadays some customers use and buy old technology-based products – vinyl sales boom again since 2007. Due to the two-sided nature of the market, customers have to get access to complementary goods. We are thus interested in technologies which have been outdated by the emergence of new technologies. The originality lies in the combination of the two areas: business models and old technologies. Furthermore, vinyl is an example not analysed in depth by scholars so far. We approached this by undertaking an in-depth literature review to generate hypotheses regarding the value-adding activities of old-technology based businesses as a basis for further research in this area. In addition the paper gives insights into the constellations to be expected over time for old technology-based businesses models in platform markets. We here focus on a neglected topic in the strategy literature which, however, bears relevance for many businesses locked into product-market systems which make it hard for them to (completely switch to a new technology emerging in the market. It is especially valuable to describe the consequences in a systematic fashion.

    This article is a systematic review of the impact of technology-based intervention on outcomes related to care providers for those who survived a stroke. Literature was identified in the PubMed, PsycINFO, Scopus, and Cochrane databases for evidence on technology-based interventions for stroke survivors' caregivers. The search was restricted for all English-language articles from 1970 to February 2015 that implied technology-based interventions. This review included studies that measured the impact of these types of approaches on one or more of the following: depression and any of the following-problem-solving ability, burden, health status, social support, preparedness, and healthcare utilization by care recipient-as secondary outcomes. Telephone or face-to-face counseling sessions were not of interest for this review. The search strategy yielded five studies that met inclusion criteria: two randomized clinical trials and three pilot/preliminary studies, with diverse approaches and designs. Four studies have assessed the primary outcome, two of which reported significant decreases in caregivers' depressive symptoms. Two studies had measured each of the following outcomes-burden, problem-solving ability, health status, and social support-and they revealed no significant differences following the intervention. Only one study assessed caregivers' preparedness and showed improved posttest scores. Healthcare services use by the care recipient was assessed by one study, and the results indicated significant reduction in emergency department visits and hospital re-admissions. Despite various study designs and small sample sizes, available data suggest that an intervention that incorporates a theoretical-based model and is designed to target caregivers as early as possible is a promising strategy. Furthermore, there is a need to incorporate a cost-benefit analysis in future studies.

  14. AXIOLOGICAL MODEL OF INSTRUCTIONAL DESIGN

    Takushevich I. A.

    2015-10-01

    Full Text Available The article presents instructional design as a new approach to the issue of developing value-oriented worldview. Scientific research and analysis led the author to summarize instructional design theory, broaden the definition of instructional design and apply it to instruction and learning in a new manner. The goal to build a pattern of instruction aimed at developing learners’ value-oriented worldview required the author to study the existing instructional design model, to analyse and generalize a number of monographs and articles devoted to the problem of building value systems and value orientations, and finally to investigate and apply the new knowledge to real life in the form of experiment. The work conducted brought the author to axiological model of instructional design, which consists of three dimensions: a linear sequence of the events from designing the instructional material to independent learning activities, interaction between a teacher and a learner, pace of learning and design. The article touches upon every dimension, level and stage of the model, describes and defines the procedures that take place on each of them, as well as suggests a possible way to visualize the model in a form of a sketch. The author also points out the advantages of using instructional design as an efficient and smart tool to organize learning and justifies the use of the new instructional design model in XXI century

  1. USING GOOGLE+ FOR INSTRUCTION

    Directory of Open Access Journals (Sweden)

    Kevin YEE

    Full Text Available Introduced in July, 2011 in a beta test of invited users only, the new social media service Google+ (or G+ quickly spread by word of mouth, and Google leader Larry Page (2011 blogged that within sixteen days it had 10 million users. By August, it had 25 million users (Cashmore, 2011. Even with slower growth ahead (still with no marketing budget, the service looks likely to crest 100 million users perhaps as early as ten months, a feat that took Facebook three years. Other social networks, most notably Facebook and Twitter, have been used increasingly as instructional tools, since they are platforms with which students are already familiar (Maloney, 2007; McLoughlin & Lee, 2007. Selwyn (2009 found that students often eschew official channels for communication in favor of less formal community-based formats such as Facebook, implying a growing need for instructional communication tools that will be used willingly by students. The question is whether Google+ can be used like Twitter or Facebook to augment instruction, or even, perhaps, to improve upon those predecessors for academic purposes. Google+ is like Twitter in that anyone can follow a given user’s posts. There is no direct “friend” relationship required to read the posts written by others. However, it also approximates some features of Facebook. Rather than friends sorted into “lists” like in Facebook, Google+ allows users to place feeds into one or more “circles,” the better to monitor (or control the flow of information to and from different audiences. Circles are more intuitive, and more central to the experience, than the Facebook lists. They provide an explicit organizational structure, compared to the less-obvious listing functionality, which feels like an afterthought, found in Facebook.

    Adolescent farmworkers are exposed to loud noise during farm activities. We present a prospective study that evaluated the efficacy of low-cost, technology-based intervention approaches in high schools to enhance the use of hearing protection among adolescent farmworkers. Six high schools in Iowa that agreed to participate in the study were divided into three equal groups through cluster-randomisation with each group receiving one of the three formats of hearing protection intervention: (a) classroom training, (b) classroom training coupled with smartphone app training and (c) computer training. Participants completed baseline (pre-training) and six-week post-intervention surveys for assessing hearing protection knowledge, attitudes and behaviour. Seventy participants from six schools were initially enrolled but 50 completed both pre- and post-intervention surveys. In most cases, all three groups showed significant improvement in hearing protection knowledge, attitude and frequency of use from pre- to post-intervention. However, changes between groups were statistically non-significant. Although all three formats led to improvements on hearing protection knowledge, attitude and behaviour, the findings of the study, perhaps due to the small sample size, did not allow us to detect whether technology-based hearing protection interventions were more effective than the traditional face-to-face training for adolescent farmworkers.

  3. Performance of SSE and AVX Instruction Sets

    CERN Document Server

    Jeong, Hwancheol; Lee, Weonjong; Myung, Seok-Ho

    2012-01-01

    SSE (streaming SIMD extensions) and AVX (advanced vector extensions) are SIMD (single instruction multiple data streams) instruction sets supported by recent CPUs manufactured in Intel and AMD. This SIMD programming allows parallel processing by multiple cores in a single CPU. Basic arithmetic and data transfer operations such as sum, multiplication and square root can be processed simultaneously. Although popular compilers such as GNU compilers and Intel compilers provide automatic SIMD optimization options, one can obtain better performance by a manual SIMD programming with proper optimization: data packing, data reuse and asynchronous data transfer. In particular, linear algebraic operations of vectors and matrices can be easily optimized by the SIMD programming. Typical calculations in lattice gauge theory are composed of linear algebraic operations of gauge link matrices and fermion vectors, and so can adopt the manual SIMD programming to improve the performance.

  4. The equivalence of learning paths in early science instruction: effect of direct instruction and discovery learning.

    Klahr, David; Nigam, Milena

    2004-10-01

    In a study with 112 third- and fourth-grade children, we measured the relative effectiveness of discovery learning and direct instruction at two points in the learning process: (a) during the initial acquisition of the basic cognitive objective (a procedure for designing and interpreting simple, unconfounded experiments) and (b) during the subsequent transfer and application of this basic skill to more diffuse and authentic reasoning associated with the evaluation of science-fair posters. We found not only that many more children learned from direct instruction than from discovery learning, but also that when asked to make broader, richer scientific judgments, the many children who learned about experimental design from direct instruction performed as well as those few children who discovered the method on their own. These results challenge predictions derived from the presumed superiority of discovery approaches in teaching young children basic procedures for early scientific investigations.

    2014-01-01

    The development of a new technology based on patient-specific modelling for personalised healthcare in the case of atherosclerosis is presented. Atherosclerosis is the main cause of death in the world and it has become a burden on clinical services as it manifests itself in many diverse forms, such as coronary artery disease, cerebrovascular disease/stroke and peripheral arterial disease. It is also a multifactorial, chronic and systemic process that lasts for a lifetime, putting enormous financial and clinical pressure on national health systems. In this Letter, the postulate is that the development of new technologies for healthcare using computer simulations can, in the future, be developed as in-silico management and support systems. These new technologies will be based on predictive models (including the integration of observations, theories and predictions across a range of temporal and spatial scales, scientific disciplines, key risk factors and anatomical sub-systems) combined with digital patient data and visualisation tools. Although the problem is extremely complex, a simulation workflow and an exemplar application of this type of technology for clinical use is presented, which is currently being developed by a multidisciplinary team following the requirements and constraints of the Vascular Service Unit at the University College Hospital, London.

    2016-01-01

    The adoption of Information and Communication Technologies (ICT) in environmental management has become a significant demand nowadays with the rapid growth of environmental information. This paper presents a prototype Environmental Management Information System (EMIS) that was developed to provide a systematic way of managing environmental data and human resources of an environmental organization. The system was designed using programming languages, a Database Management System (DBMS) and other technologies and programming tools and combines information from the relational database in order to achieve the principal goals of the environmental organization. The developed application can be used to store and elaborate information regarding: human resources data, environmental projects, observations, reports, data about the protected species, environmental measurements of pollutant factors or other kinds of analytical measurements and also the financial data of the organization. Furthermore, the system supports the visualization of spatial data structures by using geographic information systems (GIS) and web mapping technologies. This paper describes this prototype software application, its structure, its functions and how this system can be utilized to facilitate technology-based environmental management and decision-making process.

    Full Text Available This paper depicts a study carried out in Rwanda concerning university students who participated in a contest to produce short documentary films. The purpose of this research is to conceptualize these kinds of technology-based learning projects (TBLPs through a sociocultural perspective. The methodology included focus-group discussions and field notes to collect empirical data. The findings reveal that the more educational technologies capture objects of learning positioned in the students’ sociocultural proximity, the more focused the learners’ attention is on these objects. The study shows also that a change in learning projects may depend to a large extent on whether the technology relates to the students’ sociocultural proximity, that is, taking into consideration students’ physical, cultural, and contextual real world. The study recommends a community of learning/inquiry embedded in a collaborative, problem-solving dynamic involving cognitive support from peers, teachers, external specialists, and the wider community.

    A new modulation format in optical fiber communication system, the eight differential phase shift keying (8DPSK) of multi-phase modulation technology based on carrier-suppressed return-to-zero (CSRZ) is proposed in this paper. The formulae of CSRZ-8DPSK modem methods are derived theoretically and the methods are demonstrated. Spectra based on CSRZ and CSRZ-8DPSK modulation methods and their eye diagrams by simulation with MATLAB are obtained. The results show that the CSRZ-8DPSK modulation methods have narrower spectra with higher efficiency. The performance of eye diagrams is also much satisfactory after demodulation, suggesting some possible applications of the methods in the next generation of optical fiber communications.

    A confocal micro-X-ray fluorescence (MXRF) technology based on polycapillary X-ray optics was proposed for determining surface topography. This confocal topography method involves elemental sensitivity and can be used to classify the objects according to their elemental composition while obtaining their surface topography. To improve the spatial resolution of this confocal topography technology, the center of the confocal micro-volume was overlapped with the output focal spot of the polycapillary X-ray, focusing the lens in the excitation channel. The input focal spot of the X-ray lens parallel to the detection channel was used to determine the surface position of the sample. The corresponding surface adaptive algorithm was designed to obtain the surface topography. The surface topography of a ceramic chip was obtained. This confocal MXRF surface topography method could find application in the materials sciences.

    Although patient preference is a core value within the context of patient-centered models of care, little attention has been paid to determining patient preference for instructional media. Nurses have traditionally used verbal face-to-face instruction as the mainstay of patient education, with written materials being used extensively as teaching guides to supplement verbal instruction or for instructional reinforcement. However, advances in technology have made possible the adding of video instruction to nurses' repertoire of instructional media. The purpose of this study was to determine patients' media preferences (verbal, video, written) when receiving instructional reinforcement about self-care needed to prevent radiation dermatitis. The current study was conducted as a secondary analysis of data from a process improvement initiative. In the parent study, patients received multimedia education related to skin care to prevent radiation dermatitis. This secondary analysis examined patient preference for verbal, video, or written education reinforcement at treatment weeks 1 and 3. Results suggest that, when given a choice, verbal and video reinforcement are preferred over written reinforcement.

    [This paper is part of the Focused Collection on Preparing and Supporting University Physics Educators.] The lack of knowledge about how to effectively spread and sustain the use of research-based instructional strategies is currently a significant barrier to the improvement of undergraduate physics education. In this paper we address this lack of knowledge by reporting on an interview study of 35 physics faculty, of varying institution types, who were self-reported users of, former users of, or knowledgeable nonusers of the research-based instructional strategy Peer Instruction. Interview questions included in this analysis focused on the faculty's experiences, knowledge, and use of Peer Instruction, along with general questions about current and past teaching methods used by the interviewee. The primary findings include the following: (i) Faculty self-reported user status is an unreliable measure of their actual practice. (ii) Faculty generally modify specific instructional strategies and may modify out essential components. (iii) Faculty are often unaware of the essential features of an instructional strategy they claim to know about or use. (iv) Informal social interactions provide a significant communication channel in the dissemination process, in contrast to the formal avenues of workshops, papers, websites, etc., often promoted by change agents, and (v) experience with research-based strategies as a graduate student or through curriculum development work may be highly impactful. These findings indicate that educational transformation can be better facilitated by improving communication with faculty, supporting effective modification by faculty during implementation, and acknowledging and understanding the large impact of informal social interactions as a mode of dissemination.

    2009-02-01

    Theoretical and methodological advances in the cognitive and learning sciences can greatly inform curriculum and instruction in biomedicine and also educational programs in biomedical informatics. It does so by addressing issues such as the processes related to comprehension of medical information, clinical problem-solving and decision-making, and the role of technology. This paper reviews these theories and methods from the cognitive and learning sciences and their role in addressing current and future needs in designing curricula, largely using illustrative examples drawn from medical education. The lessons of this past work are also applicable, however, to biomedical and health professional curricula in general, and to biomedical informatics training, in particular. We summarize empirical studies conducted over two decades on the role of memory, knowledge organization and reasoning as well as studies of problem-solving and decision-making in medical areas that inform curricular design. The results of this research contribute to the design of more informed curricula based on empirical findings about how people learn and think, and more specifically, how expertise is developed. Similarly, the study of practice can also help to shape theories of human performance, technology-based learning, and scientific and professional collaboration that extend beyond the domain of medicine. Just as biomedical science has revolutionized health care practice, research in the cognitive and learning sciences provides a scientific foundation for education in biomedicine, the health professions, and biomedical informatics.

    Unskilled writers in a large urban university were taught summarization strategies based on T. A. van Dijk and W. Kintsch's (1983) text-processing theory. College freshmen enrolled in a prefreshman writing course (n = 147) were randomly assigned to three conditions for 2 days of classroom instruction in constructing a summary. Summarization instruction conditions were argument repetition or generalization with a control group taught to examine personal judgments of importance. Analysis of test summaries showed instruction in generalization was significantly more effective for stating a thesis statement. Both argument repetition and generalization were significantly more effective than the control condition in judging the importance of content. Implications for further research and for reading instruction are discussed. Copyright 2001 Academic Press.

    Full Text Available Venture capital backed enterprises represent a low proportion of companies, even of innovative ones. The research question was, whether these companies have an important role in innovation and economic growth in Hungary compared to other countries. In the first part of the article I present the theoretical background of technology-based small firms, highlighting the most important models and theories of the economic impact and the special development of innovative technology-oriented small firms. In the second part of the article I present the status of the most important indicators of innovation in connection with entrepreneurship, than I elaborate on the measures of start-ups, mainly the high-tech ones with high-growth potential. I describe the current position of venture capital industry, detailing the venture capital investments, with particular emphasis on classical venture capital investments that points out the number and the amount of venture capital investments financing early stage firms with high-growth potential. At the end I summarize the status of Hungarian technology-based small firms and their possibilities to get financial sources form venture capital investors, with regards to the status and the prospects of the JEREMIE program. In Hungary the number of internationally competitive firms, ready and willing to obtain venture capital, is much lower than in the US or Western European countries. Hungary could take advantage of its competitive edges in some special fields of innovation. The efficiency of information flow would reduce the information gap between the demand and the supply side of the venture capital market and more Hungarian firms could be internationally successful through venture capital financing. The recent years’ policy and special programs like JEREMIE generated more transactions, that helped to inform the entrepreneurs about venture capital and helped to co-invest public resources with private equity more

    People with low-functioning ASD and other disabilities often find it difficult to understand the symbols traditionally used in educational materials during the learning process. Technology-based interventions are becoming increasingly common, helping children with cognitive disabilities to perform academic tasks and improve their abilities and knowledge. Such children often find it difficult to perform certain tasks contained in educational materials since they lack necessary skills such as abstract reasoning. In order to help these children, the authors designed and created SIGUEME to train attention and the perceptual and visual cognitive skills required to work with and understand graphic materials and objects. A pre-test/post-test design was implemented to test SIGUEME. Seventy-four children with low-functioning ASD (age=13.47, SD=8.74) were trained with SIGUEME over twenty-five sessions and compared with twenty-eight children (age=12.61, SD=2.85) who had not received any intervention. There was a statistically significant improvement in the experimental group in Attention (W=-5.497, p<0.001). There was also a significant change in Association and Categorization (W=2.721, p=0.007) and Interaction (W=-3.287, p=0.001). SIGUEME is an effective tool for improving attention, categorization and interaction in low-functioning children with ASD. It is also a useful and powerful instrument for teachers, parents and educators by increasing the child's motivation and autonomy. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2017-02-01

    In an effort to maximize a student’s academic growth, one of the tools available to educators is the explicit instruction. Explicit instruction is marked by a series of support or scaffold, where the students will be guided through the learning process with a clear statement of purpose and a reason for learning new skills, a clear explanation and demonstration of learning targets, supported and practiced with independent feedback until mastery has been achieved. The technology development trend of todays, requires an adjustment in the development of learning object that supports the achievement of explicit instruction targets. This is where the gamification position is. In the role as a pedagogical strategy, the use of gamification preformance study class is still relatively new. Gamification not only use the game elements and game design techniques in non-game contexts, but also to empower and engage learners with the ability of motivation on learning approach and maintains a relaxed atmosphere. With using Reseach and Development methods, this paper presents the integration of technology (which in this case using the concept of gamification) in explicit instruction settings and the impact on the improvement of students’ understanding.

Five sets of video data (>250 h) documenting how learners were instructed to fly aeroplanes, drive cars and ride bicycles in real life traffic were examined to reveal some common features of correction...... exchanges. Through detailed multimodal analysis of participants’ actions, it is shown how instructors systematically elaborate their corrective instructions to include relevant information about the trouble and remedial action – a practice we refer to as unpacking corrections. It is proposed...... that the practice of unpacking the local particulars of corrections (i) provides for the instructional character of the interaction, and (ii) is highly sensitive to the relevant physical and mobile contingencies. These findings contribute to the existing literature on the interactional organisation of correction...

    Rothman, Alan H.

    This study reports the results of research designed to examine the impact of computer-based science instruction on elementary school level students' science content achievement, their attitude about science learning, their level of critical thinking-inquiry skills, and their level of cognitive and English language development. The study compared these learning outcomes resulting from a computer-based approach compared to the learning outcomes from a traditional, textbook-based approach to science instruction. The computer-based approach was inherent in a curriculum titled The Voyage of the Mimi , published by The Bank Street College Project in Science and Mathematics (1984). The study sample included 209 fifth-grade students enrolled in three schools in a suburban school district. This sample was divided into three groups, each receiving one of the following instructional treatments: (a) Mixed-instruction primarily based on the use of a hardcopy textbook in conjunction with computer-based instructional materials as one component of the science course; (b) Non-Traditional, Technology-Based -instruction fully utilizing computer-based material; and (c) Traditional, Textbook-Based-instruction utilizing only the textbook as the basis for instruction. Pre-test, or pre-treatment, data related to each of the student learning outcomes was collected at the beginning of the school year and post-test data was collected at the end of the school year. Statistical analyses of pre-test data were used as a covariate to account for possible pre-existing differences with regard to the variables examined among the three student groups. This study concluded that non-traditional, computer-based instruction in science significantly improved students' attitudes toward science learning and their level of English language development. Non-significant, positive trends were found for the following student learning outcomes: overall science achievement and development of critical thinking

    Full Text Available A common market segmentation premise for products and services rules consumer behavior as the segmentation center piece. Would this be the logic for segmentation used by small technology based companies? In this article we target at determining the principles of market segmentation used by a vitiwinery company, as research object. This company is recognized by its products excellence, either in domestic as well as in the foreign market, among 13 distinct countries. The research method used is a case study, through information from the company’s CEOs and crossed by primary information from observation and formal registries and documents of the company. In this research we look at sparkling wines market segmentation. Main results indicate that the winery studied considers only technological elements as the basis to build a market segment. One may conclude that a market segmentation for this company is based upon technological dominion of sparkling wines production, aligned with a premium-price policy. In the company, directorship believes that as sparkling wines market is still incipient in the country, sparkling wine market segments will form and consolidate after the evolution of consumers tasting preferences, depending on technologies that boost sparkling wines quality. 

  8. Technology-Based Innovations in Child Maltreatment Prevention Programs: Examples from SafeCare®

    2014-08-01

    Full Text Available Each year, hundreds of thousands of children in the U.S. are victims of child maltreatment. Experts recommend behavioral, skill-based parent training programs as a strategy for the prevention of child abuse and neglect. These programs can be enhanced using innovative technology strategies. This paper presents a brief history of the use of technology in SafeCare®, a home visiting program shown to prevent child neglect and physical abuse, and highlights current work that takes a technology-based hybrid approach to SafeCare delivery. With this unique approach, the provider brings a tablet computer to each session, and the parent interacts with the software to receive psychoeducation and modeling of target skills. The provider and parent then work together to practice the targeted skills until mastery is achieved. Initial findings from ongoing research of both of these strategies indicate that they show potential for improving engagement and use of positive parenting skills for parents and ease of implementation for providers. Future directions for technology enhancements in SafeCare are also presented.

    2013-03-01

    Research devoted to the development of therapeutic, behavioral interventions for substance use disorders (SUDs) that can be accessed and delivered via computer and mobile technologies has increased rapidly during the past decade. Numerous recent reviews of this literature have supported the efficacy of technology-based interventions (TBIs), but have also revealed their great heterogeneity and a limited understanding of treatment mechanisms. We conducted a "review of reviews" focused on summarizing findings of previous reviews with respect to moderators of TBIs' efficacy, and present an organizing framework of considerations involved in designing and evaluating TBIs for SUDs. The four primary elements that comprise our framework are Accessibility, Usage, Human Contact, and Intervention Content, with several sub-elements within each category. We offer some suggested directions for future research grouped within these four primary considerations. We believe that technology affords unique opportunities to improve, support, and supplement therapeutic and peer relationships via dynamic applications that adapt to individuals' constantly changing motivation and treatment needs. We hope that our framework will aid in guiding programmatic progress in this exciting field.

  10. An Analysis of Knowledge Sharing Approaches for Emerging-technology-based Strategic Alliances in Electronic Industry

    LIU Ju; LI Yong-jian

    2006-01-01

    Emerging technologies are now initiating new industries and transforming old ones with tremendous power. They are different games compared with established technologies with distinctive characteristics of knowledge management in knowledge-based and technological-innovation-based competition. How to obtain knowledge advantage and enhance competences by knowledge sharing for emerging-technology-based strategic alliances (ETBSA) is what we concern in this paper. On the basis of our previous work on emerging technologies'distinctive attributes, we counter the wide spread presumption that the primary purpose of strategic alliances is knowledge acquiring by means of learning. We offers new insight into the knowledge sharing approaches of ETBSAs - the knowledge integrating approach by which each member firm integrates its partner's complementary knowledge base into the products and services and maintains its own knowledge specialization at the same time. So that ETBSAs should plan and practice their knowledge sharing strategies from the angle of knowledge integrating rather than knowledge acquiring. A four-dimensional framework is developed to analyze the advantages and disadvantages of these two knowledge sharing approaches. Some cases in electronic industry are introduced to illustrate our point of view.

    Guided by the Behavioral Vaccine Theory of prevention, this study uses a no-control group design to examine intervention variables that predict favorable changes in depressive symptoms at 6- to 8-week follow-up in at-risk adolescents who participated in a primary care, Internet-based prevention program. Participants included 83 adolescents from primary care settings ages 14 to 21 (M = 17.5, SD = 2.04), 56.2% female, with 41% non-White. Participants completed self-report measures, met with a physician, and then completed a 14-module Internet intervention targeting the prevention of depression. Linear regression models indicated that several intervention factors (duration on website in days, the strength of the relationship with the physician, perceptions of ease of use, and the perceived relevance of the material presented) were significantly associated with greater reductions in depressive symptoms from baseline to follow-up. Automatic negative thoughts significantly mediated the relation between change in depressive symptoms scores and both duration of use and physician relationship. Several intervention variables predicted favorable changes in depressive symptom scores among adolescents who participated in an Internet-based prevention program, and the strength of two of these variables was mediated by automatic negative thoughts. These findings support the importance of cognitive factors in preventing adolescent depression and suggest that modifiable aspects of technology-based intervention experience and relationships should be considered in optimizing intervention design.

    2008-03-01

    Policy-makers, administrators, researchers, and teachers are increasingly vested in ensuring the quality of preschool instruction, particularly in the areas of language and literacy. This research was conducted to characterize the quality of language and literacy instruction in 135 publicly-funded preschool classrooms serving at-risk pupils. As all teachers in these classrooms were implementing the same language and literacy curriculum, we also studied the interrelationships among procedural fidelity to a prescribed curriculum and the quality of language and literacy instruction, determining whether procedural fidelity is associated or disassociated with quality instruction. Results showed that the quality of language and literacy instruction in classrooms was low, with few teachers delivering high quality instruction. Although teachers were able to implement a prescribed language and literacy curriculum with a high degree of procedural fidelity, this was not associated with quality instruction. Few structural characteristics of classrooms of teachers were systematically associated with quality of instruction. Findings have important implications for professional development of teachers by suggesting a need for a sustained and coherent focus on the process of instruction to elevate instructional quality in language and literacy.

    2016-09-01

    Maneuvering target prediction and tracking technology is widely used in both military and civilian applications, the study of those technologies is all along the hotspot and difficulty. In the Electro-Optical acquisition-tracking-pointing system (ATP), the primary traditional maneuvering targets are ballistic target, large aircraft and other big targets. Those targets have the features of fast velocity and a strong regular trajectory and Kalman Filtering and polynomial fitting have good effects when they are used to track those targets. In recent years, the small unmanned aerial vehicles developed rapidly for they are small, nimble and simple operation. The small unmanned aerial vehicles have strong maneuverability in the observation system of ATP although they are close-in, slow and small targets. Moreover, those vehicles are under the manual operation, therefore, the acceleration of them changes greatly and they move erratically. So the prediction and tracking precision is low when traditional algorithms are used to track the maneuvering fly of those targets, such as speeding up, turning, climbing and so on. The interacting multiple model algorithm (IMM) use multiple models to match target real movement trajectory, there are interactions between each model. The IMM algorithm can switch model based on a Markov chain to adapt to the change of target movement trajectory, so it is suitable to solve the prediction and tracking problems of the small unmanned aerial vehicles because of the better adaptability of irregular movement. This paper has set up model set of constant velocity model (CV), constant acceleration model (CA), constant turning model (CT) and current statistical model. And the results of simulating and analyzing the real movement trajectory data of the small unmanned aerial vehicles show that the prediction and tracking technology based on the interacting multiple model algorithm can get relatively lower tracking error and improve tracking precision

    The grant NAG-1 -2125, Technical Education Outreach in Materials Science and Technology, based on NASA s Materials Research, involves collaborative effort among the National Aeronautics and Space Administration s Langley Research Center (NASA-LaRC), Norfolk State University (NSU), national research centers, private industry, technical societies, colleges and universities. The collaboration aims to strengthen math, science and technology education by providing outreach related to materials science and technology (MST). The goal of the project is to transfer new developments from LaRC s Center for Excellence for Structures and Materials and other NASA materials research into technical education across the nation to provide educational outreach and strengthen technical education. To achieve this goal we are employing two main strategies: 1) development of the gateway website and 2) using the National Educators Workshop: Update in Engineering Materials, Science and Technology (NEW:Updates). We have also participated in a number of national projects, presented talks at technical meetings and published articles aimed at improving k-12 technical education. Through the three years of this project the NSU team developed the successful MST-Online site and continued to upgrade and update it as our limited resources permitted. Three annual NEW:Updates conducted from 2000 though 2002 overcame the challenges presented first by the September 11,2001 terrorist attacks and the slow U.S. economy and still managed to conduct very effective workshops and expand our outreach efforts. Plans began on NEW:Update 2003 to be hosted by NASA Langley as a part of the celebration of the Centennial of Controlled Flight.

  3. DSLM Instructional Approach to Conceptual Change Involving Thermal Expansion

    Science.gov (United States)

    She, Hsiao-Ching

    2003-01-01

    This article examines the process of students' conceptual change involving thermal expansion as a result of employing the Dual Situated Learning Model (DSLM) (She, 2001, 2002) as a classroom instructional approach. The dual situated learning events of this model are designed according to the students' ontological viewpoint of the science concepts as well as the nature of these concepts. Moreover, these events serve two functions in creating dissonance with the pre-existing knowledge and providing new schema for constructing a more scientific view of the concept. DSLM has been shown to promote students' conceptual change using one-to-one instructional procedure (She, 2002). This study further demonstrates that DSLM holds great potential to facilitate the conceptual change process involving thermal expansion through classroom instruction, even the difficult concept or higher hierarchical level one.

    Nelson, Adrienne Fleurette

    The purpose of this mixed method research study was to examine the constructivist beliefs and instructional practices of secondary science teachers. The research also explored situations that impacted whether or not student centered instruction occurred. The study revealed science teachers held constructive beliefs pertaining to student questioning of the learning process and student autonomy in interacting with other learners. Teachers held the least constructivist beliefs pertaining to student teacher collaboration on lesson design. Additionally, teacher beliefs and practice were not congruent due to instructional practices being deemed less constructivist than reported. The study found that curricular demands, teacher perceptions about students, inadequate laboratory resources, and the lack of teacher understanding about the components of constructivist instruction inhibited student centered instruction. The results of this study led to six recommendations that can be implemented by school districts in collaboration with science teachers to promote constructivist instruction.

    Mechanisms are provided for inserting indicated instructions for tracking and indicating exceptions in the execution of vectorized code. A portion of first code is received for compilation. The portion of first code is analyzed to identify non-speculative instructions performing designated non-speculative operations in the first code that are candidates for replacement by replacement operation-and-indicate instructions that perform the designated non-speculative operations and further perform an indication operation for indicating any exception conditions corresponding to special exception values present in vector register inputs to the replacement operation-and-indicate instructions. The replacement is performed and second code is generated based on the replacement of the at least one non-speculative instruction. The data processing system executing the compiled code is configured to store special exception values in vector output registers, in response to a speculative instruction generating an exception condition, without initiating exception handling.

  7. How explicit and implicit test instructions in an implicit learning task affect performance.

    Directory of Open Access Journals (Sweden)

    Arnaud Witt

    Full Text Available Typically developing children aged 5 to 8 years were exposed to artificial grammar learning. Following an implicit exposure phase, half of the participants received neutral instructions at test while the other half received instructions making a direct, explicit reference to the training phase. We first aimed to assess whether implicit learning operated in the two test conditions. We then evaluated the differential impact of age on learning performances as a function of test instructions. The results showed that performance did not vary as a function of age in the implicit instructions condition, while age effects emerged when explicit instructions were employed at test. However, performance was affected differently by age and the instructions given at test, depending on whether the implicit learning of short or long units was assessed. These results suggest that the claim that the implicit learning process is independent of age needs to be revised.
