Studies highlight that using appropriate strategies during problem solving is important to improve problem-solving skills and draw attention to the fact that using these skills is an important part of students' self-regulated learning ability. Studies on this matter view the self-regulated learning ability as key to improving problem-solving skills. The aim of this study is to investigate the relationship between mathematical problem-solving skills and the three dimensions of self-regulated learning (motivation, metacognition, and behaviour), and whether this relationship is of a predictive nature. The sample of this study consists of 323 students from two public secondary schools in Istanbul. In this study, the mathematics homework behaviour scale was administered to measure students' homework behaviours. For metacognition measurements, the mathematics metacognition skills test for students was administered to measure offline mathematical metacognitive skills, and the metacognitive experience scale was used to measure the online mathematical metacognitive experience. The internal and external motivational scales used in the Programme for International Student Assessment (PISA) test were administered to measure motivation. A hierarchic regression analysis was conducted to determine the relationship between the dependent and independent variables in the study. Based on the findings, a model was formed in which 24% of the total variance in students' mathematical problem-solving skills is explained by the three sub-dimensions of the self-regulated learning model: internal motivation (13%), willingness to do homework (7%), and post-problem retrospective metacognitive experience (4%).

Single-determinantal states consisting of localized, non-overlapping single-particle orbitals are used in comparison with those made up of plane wave ones to show that neutron matter prefers a "crystalline" configuration beyond a density of around 0.07 fm -3 for the ν0 homework potential. The total energy is not too high above the best Jastrow-correlated calculations. No such effect is found for the ν1 homework potential. The analogous question for the electron gas is also studied.

Full Text Available A problem has been observed that creates difficulties in the normal and productive development of the English courses. Without any doubt, doing homework is very important in the learning process of a new language. Doubtless it affects the student’s active participation in the classroom and his relationship to partners and teachers. Because of this, a research project was done with the aim to finding out strategies to ensure students do homework and make it part of the learning process, erasing the image of homework as a punishment.

The primary aim of the present study was to evaluate if previously reported treatment gains of a parent management training (PMT) program, administered via Internet, were retained from post to the 18-month follow-up. Another aim was to evaluate homework compliance as a predictor of short and long-term outcomes. Participants were parents of 58 children (3-11 years) with conduct problems who received a 10-week self-directed PMT program, with limited therapist support. Parents of 32 children (55.2 %) responded at all measurement point (baseline, post-test and follow-up) and analyses showed that child conduct problems continued to decrease during the 18-month period after the intervention whereas parenting skills deteriorated somewhat from post treatment. Pre- to post-treatment change in child conduct problems was predicted by parental engagement in homework assignments intended to reduce negative child behaviors. The findings provide support for the use of Internet-based PMT and stress the importance of parental compliance to homework training.

We examine the relationship between homework completion and exam performance for students having different physics aptitudes for five different semesters of an introductory electricity and magnetism course. In our analysis, we plot exam scores versus homework completion scores and calculate the slopes of the line fits and the Pearson correlations. On average, completing many homework problems correlated to better exam scores only for students with high physics aptitude. Low aptitude physics students had a negative correlation between exam performance and completing homework; the more homework problems they did, the worse their performance was on exams. One explanation for this effect is that the assigned homework problems placed an excessive cognitive load on low aptitude students. As a result, no learning or even negative learning might have taken place when low aptitude students attempted to do assigned homework. Another explanation is based on the fact that the negative benefit effects first appeared when ...

Full Text Available We examine how student aptitudes impact how much students learn from doing graded online and written homework in an introductory electricity and magnetism course. Our analysis examines the correlation between successful homework completion rates and exam performance as well as how changes in homework completion correlate with changes in exam scores for students with different physics aptitudes. On average, successfully completing many homework problems correlated to better exam scores only for students with high physics aptitude. On the other hand, all other students showed zero or even a negative correlation between successful homework completion and exam performance. Low- and medium-aptitude students who did more homework did no better and sometimes scored lower on exams than their low- and medium-aptitude peers who did less homework. Our work also shows that long-term changes in homework completion correlated to long-term changes in exam scores only for students with high physics aptitude, but not for students with medium or low aptitude. We offer several explanations for the disparity in homework learning gains, including cognitive load theory, ineffective homework strategies, and various mismatches between homework and exams. Several solutions are proposed to address these possible deficiencies in graded online and written homework.

Patterns, correlates, and reduction of homework copying
Palazzo, David J.; Lee, Young-Jin; Warnakulasooriya, Rasil; Pritchard, David E.
2010-06-01
Submissions to an online homework tutor were analyzed to determine whether they were copied. The fraction of copied submissions increased rapidly over the semester, as each weekly deadline approached and for problems later in each assignment. The majority of students, who copied less than 10% of their problems, worked steadily over the three days prior to the deadline, whereas repetitive copiers (those who copied >30% of their submitted problems) exerted little effort early. Importantly, copying homework problems that require an analytic answer correlates with a 2(σ) decline over the semester in relative score for similar problems on exams but does not significantly correlate with the amount of conceptual learning as measured by pretesting and post-testing. An anonymous survey containing questions used in many previous studies of self-reported academic dishonesty showed ˜1/3 less copying than actually was detected. The observed patterns of copying, free response questions on the survey, and interview data suggest that time pressure on students who do not start their homework in a timely fashion is the proximate cause of copying. Several measures of initial ability in math or physics correlated with copying weakly or not at all. Changes in course format and instructional practices that previous self-reported academic dishonesty surveys and/or the observed copying patterns suggested would reduce copying have been accompanied by more than a factor of 4 reduction of copying from ˜11% of all electronic problems to less than 3%. As expected (since repetitive copiers have approximately three times the chance of failing), this was accompanied by a reduction in the overall course failure rate. Survey results indicate that students copy almost twice as much written homework as online homework and show that students nationally admit to more academic dishonesty than MIT students.

Full Text Available The World Wide Web influences education and our lives in many ways. Nowadays, Web-based homework has been becoming widespread practice in physics courses and some other courses as well. Although are some disputes whether this is an encouraging or risky development for student learning, there is limited research assessing the pedagogical effect of changing the medium from written, hand-graded homework to online oriented, computer-graded homework. In this study, web-oriented homework system is developed to assess students’ introductory physics course performance. Later on, these results are compared with paper-based (peer homework performance for mid enrollment physics courses. One of two identical sections of introductory physics course students received paper-based, hand graded group homework while the other received the individual web-based homework. Then two groups’ on conceptual and problem-solving performance measures are compared. No significant differences were found in students’ Force Concept Inventory (FCI test scores; however, average homework performance scores were significant that could be attributed to the homework method used in favor of paper-based peer homework group.
Changing Student Attitudes using Andes, An Intelligent Homework System
van de Sande, Brett; Vanlehn, Kurt; Treacy, Don; Shelby, Bob; Wintersgill, Mary
2007-03-01
The size of introductory physics lectures often inhibits personal homework assistance and timely corrective feedback. Andes, an intelligent homework help system designed for two semesters of introductory physics, can fill this need by encouraging students to use sound problem solving techniques and providing immediate feedback on each step of a solution. On request, Andes provides principles-based hints based on previous student actions. A multi-year study at the U.S. Naval Academy demonstrates that students using Andes perform better than students working the same problems as graded pencil and paper homeworks. In addition, student attitude surveys show that Andes is preferred over other homework systems. These findings have implications for student attitudes toward, and mastery of, physics. See http://www.andes.pitt.edu for more information.

One Method for Inhibiting the Copying of Online Homework
Busch, Hauke
2017-10-01
Over the last several years online homework solutions have become ever more accessible to students. This is due in part to programs like Yahoo Answers, Chegg, publisher solution manuals, and other web resources that are readily available online. The student can easily search any physics homework problem posted on the web in a matter of seconds and have the solution. The results of this are an apparent increase in students copying the answers without solving the problem, which may lead to an increase in homework scores but a reduction in exam scores and an overall lower grade in the class. A secondary effect that may be observed is that tutoring centers, recitations, and supplemental instructor sessions have reduced student attendance. Some might say that the readily available solutions for homework systems such as MasteringPhysics (MP), WebAssign, etc. have greatly diminished them as a teaching tool, and for grading and assessing students' performance in a course. It is the purpose of this paper to offer a possible solution for preventing students from potentially copying online homework solutions.
Does requiring graded online homework improve physics exam performance?
Chase, Norma
2012-02-01
In a first experiment with using Mastering Physics in a first semester calculus-based course, homework and exam performance was tracked periodically during the semester. As expected, the use of novel technology (and its ability to track which students were persistently working at problem exercises) motivated many students to become more involved with work on assigned physics problems. Although there did appear to be a significant correlation between exam averages and homework scores in the upper half of the exam average distribution, individuals spanning the full range of exam averages (down to 45 percent) earned homework scores as high as those who had performed outstandingly well in exams. In this work, we present results and proposed plausible explanations for the apparent anomaly.

Students' Achievement and Homework Assignment Strategies
Fernández-Alonso, Rubén; Álvarez-Díaz, Marcos; Suárez-Álvarez, Javier; Muñiz, José
2017-01-01
The optimum time students should spend on homework has been widely researched although the results are far from unanimous. The main objective of this research is to analyze how homework assignment strategies in schools affect students' academic performance and the differences in students' time spent on homework. Participants were a representative sample of Spanish adolescents (N = 26,543) with a mean age of 14.4 (±0.75), 49.7% girls. A test battery was used to measure academic performance in four subjects: Spanish, Mathematics, Science, and Citizenship. A questionnaire allowed the measurement of the indicators used for the description of homework and control variables. Two three-level hierarchical-linear models (student, school, autonomous community) were produced for each subject being evaluated. The relationship between academic results and homework time is negative at the individual level but positive at school level. An increase in the amount of homework a school assigns is associated with an increase in the differences in student time spent on homework. An optimum amount of homework is proposed which schools should assign to maximize gains in achievement for students overall.

This study investigated how students’ prior achievement is related to their homework behaviors (i.e., time spent on homework, homework time management, and amount of homework), and to their perceptions of parental involvement in homework (i.e., parental control and parental support). A total of 1250 secondary students from 7 to 10th grade participated in the study. Structural equation models were fitted to the data, compared, and a partial mediation model was chosen. The results indicated that students’ prior academic performance was significantly associated with both of the students’ homework variables, with direct and indirect results linking achievement and homework behaviors with perceived parental control and support behaviors about homework. Low-achieving students, in particular, perceived more parental control of homework in the secondary grades. These results, together with those of previous research, suggest a recursive relationship between secondary school students’ achievement and their perceptions of parental involvement in homework, which represents the process of student learning and family engagement over time. Study limitations and educational implications are discussed. PMID:28798702

Kinds of Materialas to Use as Homework
Rincón Argüello Martha Liliana
2000-08-01
Full Text Available As our environment is basically monolingual, there is an absence of an adequate linguistic context, except for some music in English, cable TV or internet. In order to reinforce what students learn in English class, teachers try to assign extraclass exercises in order to complement students’ learning, but these exercises or homework must be attractive and interesting for them. It is clear that the kind of material used as homework is important to motivating students to do it.

The primary goal of this study was to longitudinally evaluate the homework assignment completion patterns of middle school age adolescents with ADHD, their associations with academic performance, and malleable predictors of homework assignment completion. Analyses were conducted on a sample of 104 middle school students comprehensively diagnosed with ADHD and followed for 18 months. Multiple teachers for each student provided information about the percentage of homework assignments turned in at five separate time points and school grades were collected quarterly. Results showed that agreement between teachers with respect to students assignment completion was high, with an intraclass correlation of .879 at baseline. Students with ADHD were turning in an average of 12% fewer assignments each academic quarter in comparison to teacher-reported classroom averages. Regression analyses revealed a robust association between the percentage of assignments turned in at baseline and school grades 18 months later, even after controlling for baseline grades, achievement (reading and math), intelligence, family income, and race. Cross-lag analyses demonstrated that the association between assignment completion and grades was reciprocal, with assignment completion negatively impacting grades and low grades in turn being associated with decreased future homework completion. Parent ratings of homework materials management abilities at baseline significantly predicted the percentage of assignments turned in as reported by teachers 18 months later. These findings demonstrate that homework assignment completion problems are persistent across time and an important intervention target for adolescents with ADHD.
Parents' conceptions of their homework involvement in elementary school.
Cunha, Jennifer; Rosário, Pedro; Macedo, Lúcia; Nunes, Ana Rita; Fuentes, Sonia; Pinto, Ricardo; Suárez, Natalia
2015-01-01
Homework is a universal practice used in schools, and is commonly related to academic achievement. According to literature, parental homework involvement has positive and negative aspects, depending on parents’ behaviors. Assuming a phenomenographic perspective, this study examined 4th graders’ parents’ conceptions of their involvement in homework. With the purpose of mapping the parents’ various conceptions of homework involvement, 32 semi-structured interviews were conducted and analyzed. The results show that parents’ conceptions of homework involvement have a positive meaning, and focus primarily on the role played in the promotion of academic learning by (a) fostering their children’s autonomy, (b) exerting control over their learning, and (c) providing them with emotional encouragement (when children struggle with difficulties). Given that parents perceive their involvement in their children’s homework as important, it is necessary to promote parent-teacher collaboration and parent-training workshops to improve the quality of parental homework involvement.

How different incentives affect homework completion in introductory physics courses
Kontur, F J
2013-01-01
This article quantitatively examines the effects that different incentives have on students' homework completion in introductory physics courses at the United States Air Force Academy. According to our findings, there is a strong linear relationship between the amount of course credit awarded and the amount of homework that students complete. The line fits show that, for the courses that were studied, 3-4% more homework is completed for every additional 1% of course credit awarded to students for completing homework. In addition, we find that there is a strong relationship between students' average perception of the learning benefit of homework and how much homework they complete, and that students completed 15% more homework when their average perception of homework increased by 0.5 points on a 4-point Likert scale. Finally, we find that giving students in-class quizzes that come directly from homework resulted in 15% greater homework completion than giving them in-class quizzes that were only conceptually r...

THE WAY HOMEWORK TRAVELS FROM THE CLASSROOM TO HOME
Portilla León, Martha de Jesús
2013-01-01
Full Text Available This article describes the ways in which homework in the subject of Spanish travels from classrooms to students’ homes in first and second grade. The research is based on an ethnographic perspective that can show how homework is an object of school culture, which is constructed and re-constructed by educational actors, leading to various appropriations of homework according to the social networks and relationships involved as it navigates between school and home. Therefore, homework can also be viewed as a series of cultural practices that simultaneously enable and impeded the links between school and family. The manner in which homework navigates will vary depending on school and family contexts. Family members responsible for picking up and supporting children are a major point of reference, as are the diverse cultural practices through which the teachers make explicit the homework and the supports used for its transit. This article is published in Spanish.
Homework Should Be Banned in Primary Schools in China
张巧雅
2013-01-01
Recently in China, most parents, when asked about the attitudes towards homework, favor homework as a necessity for practice because the college entrance examination still exists. Admittedly, homework guarantees students ’command of knowl-edge and better prepares one for the coming tests. However, for pupils, the assigned homework to be finished during the non-school hours is detrimental to individual health, family relationships, realization of schools ’educational goals and societal equality. In addition, homework for kids, against its original intention in practice, can’t help kids learn efficiently and thus should be banned. This essay focuses on specific reasons in various aspects why homework should be banned.
Practical Homework Assignments As Part Of Chemistry Teaching And Learning
Dragica Trivic
2010-12-01
Full Text Available The paper presents two examples of classroom practices when practical research tasks in primary and secondary school are assigned as homework. The task for primary school students was aimed at developing divergent thinking, which is evidenced and illustrated by some examples of students’ solutions. The task for secondary school students illustrates how these students are able to apply their classroom knowledge of acids, bases and indicators on the substances they can find in everyday life. The students performed the following activities: problem analysis, action planning, and equipment selection/assembling, performing the experiment, measuring (mass, volume, data recording, and drawing conclusions. The results of both tasks served as a basis for introducing new contents in the classroom and stimulated active participation of a larger number of students.Keywords:

2016-01-01
Homework is a debated issue in society and its relationship with academic achievement has been deeply studied in the last years. Nowadays, schools are multicultural stages in which students from different cultures and ethnicities work together. In this sense, the present study aims to compare homework involvement and academic achievement in a sample of native and immigrant students, as well as to study immigrant students' relationship between homework involvement and Math achievement. The sample included 1328 students, 10-16 years old from Spanish families (85.6%) or immigrant students or students of immigrant origin (14.4%) from South America, Europe, Africa, and Asia. The study was developed considering three informants: elementary and secondary students, their parents and their teachers. Results showed higher involvement in homework in native students than in immigrant. Between immigrants students, those who are more involved in homework have better academic achievement in Math at secondary grades. There weren't found gender differences on homework involvement, but age differences were reported. Immigrant students are less involved in homework at secondary grades that students in elementary grades. The study highlights the relevance of homework involvement in academic achievement in immigrant students.

By using the book "Physics for Scientists and Engineers" by Raymond A. Serway as a guide, CD problem sets for teaching a calculus-based physics course were developed, programmed, and evaluated for homework assignments during the 2003-2004 academic year at Utah State University. These CD sets were used to replace the traditionally handwritten and submitted homework sets. They included a research-based format that guided the students through problem-solving techniques using responseactivated helps and suggestions. The CD contents were designed to help the student improve his/her physics problem-solving skills. The analyzed score results showed a direct correlation between the scores obtained on the homework and the students' time spent per problem, as well as the number of helps used per problem.
Incorporating Inquiry into Upper-Level Homework Assignments: The Mini-Journal
Whittington, A. G.; Speck, A. K.; Witzig, S. B.; Abell, S. K.
2009-12-01
The U.S. National Science Education Standards provide guidelines for teaching science through inquiry, where students actively develop their understanding of science by combining scientific knowledge with reasoning and thinking skills. Inquiry activities include reading scientific literature, generating hypotheses, designing and carrying out investigations, interpreting data, and formulating conclusions. Inquiry-based instruction emphasizes questions, evidence, and explanation, the essential features of inquiry. As part of an NSF-funded project, “CUES: Connecting Undergraduates to the Enterprise of Science,” new inquiry-based homework materials were developed for two upper-level classes at the University of Missouri: Geochemistry (required for Geology majors), and Solar System Science (open to seniors and graduate students, co-taught and cross-listed between Geology and Physics & Astronomy). We engage students in inquiry-based learning by presenting homework exercises as “mini-journal” articles that follow the format of a scientific journal article, including a title, authors, abstract, introduction, methods, results, discussion and citations to peer-reviewed literature. The mini-journal provides a scaffold and serves as a springboard for students to develop and carry out their own follow-up investigation. They then present their findings in the form of their own mini-journal. Mini-journals replace traditional homework problem sets with a format that more directly reflects and encourages scientific practice. Students are engaged in inquiry-based homework which encompass doing, thinking, and communicating, while the minijournal allows the instructor to contain lines of inquiry within the limits posed by available resources. In the examples we present, research is conducted via spreadsheet modeling, where the students develop their own spreadsheets. The key differences between the old and new formats include (i) the active participation of the students in

Gender differences in the use of an online homework system in an introductory physics course
Gerd Kortemeyer
2009-05-01
Full Text Available The two genders make different use of being allowed multiple tries to solve online homework problems: male students frequently attempt to immediately solve the problem, while female students are more likely to first interact with peers and teaching assistants before entering answers. More male than female students state that they use the multiple allowed attempts to enter “random stuff,” while more female than male students state that the multiple attempts allow them to explore their own problem solving approaches without worrying or being stressed out by grades.
Academic goals, student homework engagement, and academic achievement in Primary Education
Antonio eValle
2016-03-01
Full Text Available There seems to be a general consensus in the literature that doing homework is beneficial for students. Thus, the current challenge is to examine the process of doing homework to find which variables may help students to complete the homework assigned. To address this goal, a path analysis model was fit. The model hypothesized that the way students engage in homework is explained by the type of academic goals set, and it explains the amount of time spend on homework, the homework time management, and the amount of homework done. Lastly, the amount of homework done is positively related to academic achievement. The model was fit using a sample of 535 Spanish students from the last three courses of elementary school (aged 9 to 13. Findings show that: (a academic achievement was positively associated with the amount of homework completed, (b the amount of homework completed was related to the homework time management, (c homework time management was associated with the approach to homework; (d and the approach to homework, like the rest of the variables of the model (except for the time spent on homework, was related to the student's academic motivation (i.e., academic goals.
Extending Item Response Theory to Online Homework
Kortemeyer, Gerd
2014-01-01
Item Response Theory becomes an increasingly important tool when analyzing ``Big Data'' gathered from online educational venues. However, the mechanism was originally developed in traditional exam settings, and several of its assumptions are infringed upon when deployed in the online realm. For a large enrollment physics course for scientists and engineers, the study compares outcomes from IRT analyses of exam and homework data, and then proceeds to investigate the effects of each confounding factor introduced in the online realm. It is found that IRT yields the correct trends for learner ability and meaningful item parameters, yet overall agreement with exam data is moderate. It is also found that learner ability and item discrimination is over wide ranges robust with respect to model assumptions and introduced noise, less so than item difficulty.

Full Text Available This paper presents findings from an ethnographic study of the role and meaning of mathematics homework in the lives of middle school students. The study conceptualizes and examines homework as a social practice, with a focus on how students make meaning out of their experiences and the role of identity development in meaning making. Specifically, the study examines how middle school students come to value or reject mathematics homework. Case study analyses revealed two ways of characterizing students’ experiences with homework. Students who buy into homework develop aspects of their identities related to school, math and homework that support them in valuing homework. Students who check out develop aspects of their identities that support them in rejecting homework. The concepts of buying in and checking out have implications for theory development around motivation and identity and for school practices around homework.

The purpose of the study was to investigate the effects of interactive and non-interactive science homework assignments on family involvement in homework, homework completion and accuracy, student science achievement, and student and parent attitudes about science. Most previous research on homework has examined what parental involvement results naturally, without prompts or instruction from teachers. In contrast, this study experimentally examined the effects of teacher prompts to parents for involvement in their children's homework. Two hundred and fifty-three students from 10 classes of sixth and eighth grade students participated in the study that lasted 18 weeks of the school year. Six classes of students completed the TIPS (Teachers Involve Parents In Schoolwork) interactive homework assignments, and four classes completed the non-interactive assignments that contained the same content and questions as the TIPS assignments. TIPS students received instructions to involve a parent or other family partner in certain sections of the homework assignment. ATIPS students received the same assignment with no instruction to involve another person. Results indicated that TIPS students more often involved parents in their science homework assignments than ATIPS students. However, TIPS science students reported no more parental involvement in homework than ATIPS students in subjects not assigning interactive homework. Therefore, the TIPS instructions elicited more parental involvement in homework than the ATIPS assignments. TIPS students did not differ from ATIPS students in the percent of homework returned or accuracy. Students who rated the homework more positively and involved families regularly returned more homework assignments than students who did not do so. TIPS students did earn significantly higher science report card grades than ATIPS students after controlling for background variables, teacher effects, and percent of homework returned.

Web Based Homework for CAPA in General Education Astronomy Courses
Robertson, T. H.
2002-12-01
Qualitative questions in astronomy have been developed to operate under the CAPA web-based homework system. Multiple versions of similar questions and software randomization are used to create different homework sets for each student. The questions are grouped by concept and subject to create more challenging activities from relatively simple questions. These questions have been used for three semesters in five sections of ASTRO 100 which enrolled a total of 500 students over the past two years. Student surveys consistently indicate that they like the system and believe that it helps them to learn. Cognitive measures in the form of exam and course grades do not demonstrate statistically significant improvement in sections which have used the new homework system. This is due in part to a conscious effort to create exam questions which focus on content understanding and not memorization and the persistent student habit of studying for exams by memorizing homework. Differences have been identified between female and male students in terms of completion rates and performance on homework, quiz and exam scores. This work was supported in part by funding from the George and Frances Ball Fund for Academic Excellence and the 21st Century Fund for Faculty Development.

SCHOOL HOMEWORK: THE REFLECTION OF AN EDUCATIONAL SYSTEM
Ignacio Polo Martínez
2016-07-01
Full Text Available The Spanish education system has become one of the worst, as evaluated by the PISA-OCDE assessments. The tip of the iceberg of this education systemwhich constantly proves to have truly poor results- is showing itself in the children’s homes, by the assignment of homework. Despite the fact that an increasing number of studies show evidence that assigning homework to primary school children (especially the youngest ones is useless, Spanish primary school students are overwhelmed with their school duties. Likewise, the World Health Organisation has reported that secondary school students feel they are living under high pressure due to their school responsibilities. It is imperative to enforce a change in the Spanish education system, with a clear aim of reducing homework load and students’ stress levels. Promoting the right change will provide the Spanish education system with better results and achieve students’ proper wellbeing.

Incorporating Inquiry into Upper-Level Undergraduate Homework Assignments: The Mini-Journal
Whittington, Alan; Speck, Angela; Witzig, Stephen; Abell, Sandra
2010-05-01
The US National Science Education Standards (2000) state that science should be taught through inquiry. The five essential features of classroom inquiry are that the leaner (i) engages in scientifically oriented questions, (ii) gives priority to evidence in responding to questions, (iii) formulates explanations from evidence, (iv) connects explanations to scientific knowledge, and (v) communicates and justifies explanations. One difficulty in achieving this vision at the university level lies in the common perception that inquiry be fully open and unstructured, and that its implementation will be impractical due to time and material constraints. In an NSF-funded project, "CUES: Connecting Undergraduates to the Enterprise of Science," faculty developed new inquiry-based laboratory curriculum materials using a "mini-journal" approach, which is designed as an alternative to the cookbook laboratory and represents the way that scientists do science. Here we adapt this approach to a homework assignment in an upper-level Planetary Science class, and show that inquiry is achievable in this setting. Traditional homeworks in this class consisted of problem sets requiring algebraic manipulation, computation, and in most cases an appraisal of the result Longer questions are broken down into chunks worth 1 to 4 points. In contrast, the mini-journal is a short article that is modeled in the way that scientists do and report science. It includes a title, abstract, introduction (with clear statement of the problem to be tackled), a description of the methods, results (presented as both tables and graphs), a discussion (with suggestions for future work) and a list of cited work. Students devise their research questions and hypothesis from the paper based on a logical next step in the investigation. Guiding questions in the discussion can assist the students ("it would be interesting to evaluate the effect of ..."). Students submit their own minijournal, using the same journal
HOMEWORK ACCURACY TO INCREASE THE ACADEMIC REPERTOIRE OF YOUNG CHILDREN WITH AUTISM
Lina GILIC
2016-04-01
Full Text Available There are many forms of interventions used to increase homework completion. However, there is far less research to assess homework accuracy for young children with special needs, and even less for young children diagnosed with Autism. Homework intervention methods have been proven by researchers to be effective under certain specific circumstances. Emphasis should be placed on increasing the accuracy of homework completed prior to deciding what intervention would be more effective for a particular student struggling with homework completion. Educators should take into consideration the level of participation from the children’s home, the needs of the student, and how data would be collected and communicated for homework accuracy. Data for visual analysis would identify the homework completed correctly rather than just completed, and also identify progress over time. Researchers have demonstrated that homework completed cannot determine academic skill gained which is needed for academic success for young students with or without disabilities. Homework accuracy requires greater attention and emphasis in the early childhood research. The need for research on young children with Autism is evident as it is the fastest growing neurobiological condition in the world. The inclusion of children with Autism in the general environment has also greatly increased. Recommendations for further research focused on homework accuracy are offered.

This study analyzed the effects of five types of homework follow-up practices (i.e., checking homework completion; answering questions about homework; checking homework orally; checking homework on the board; and collecting and grading homework) used in class by 26 teachers of English as a Foreign Language (EFL) using a randomized-group design. Once a week, for 6 weeks, the EFL teachers used a particular type of homework follow-up practice they had previously been assigned to. At the end of the 6 weeks students completed an EFL exam as an outcome measure. The results showed that three types of homework follow-up practices (i.e., checking homework orally; checking homework on the board; and collecting and grading homework) had a positive impact on students' performance, thus highlighting the role of EFL teachers in the homework process. The effect of EFL teachers' homework follow-up practices on students' performance was affected by students' prior knowledge, but not by the number of homework follow-up sessions.

The dilemma of giving mathematics homework from the perspective of pre-service elementary teachers
Von Anthony Gayas Torio
2016-01-01
Full Text Available Homework is defined as an additional task that a student does outside of the school. This added activity is in recognition of the necessity to spend additional time for subjects such as Mathematics. The dilemma comes in the form of the advantages and disadvantages that can be derived from homework. Studies have revealed varying effects of homework to students on academic and non-academic areas. Teachers are at the forefront of the decision towards the giving or not of homework. Pre-service teachers at the elementary level represent the future leaders of the educational system and should be acquainted and involved at the onset of the dilemma. The main objective of this study is to determine the perspective of pre-service elementary teachers towards homework. The anatomy of their belief can be a key towards addressing the issue via teacher training. The descriptive method of research was used through case studies. Constant comparative method was used to analyze results. Salient results revealed that the subjects favor the giving homework on the following grounds: it helps add knowledge, confidence and satisfaction. Those who do not favor homework find it as an additional burden and a source of additional stress. Difficulties in complying with homework are usually associated with limited time, bad influence of peers and teacher factor. Students usually spend late nights to comply with homework and are unable to perform at the best of their potentials.

Full Text Available Abstract Background Most physical activity and nutrition interventions in children focus on the school setting; however, evidence suggests that children are less active and have greater access to unhealthy food at home. The aim of this pilot study was to examine the efficacy of a compulsory homework programme for increasing physical activity and healthy eating in children. Methods The six-week 'Healthy Homework' programme and complementary teaching resource was developed under the guidance of an intersectoral steering group. Eight senior classes (year levels 5-6 from two diverse Auckland primary schools were randomly assigned into intervention and control groups. A total of 97 children (57 intervention, 40 control aged 9-11 years participated in the evaluation of the intervention. Daily step counts were monitored immediately before and after the intervention using sealed multiday memory pedometers. Screen time, sports participation, active transport to and from school, and the consumption of fruits, vegetables, unhealthy foods and drinks were recorded concurrently in a 4-day food and activity diary. Results Healthy Homework resulted in a significant intervention effect of 2,830 steps.day-1 (95% CI: 560, 5,300, P = 0.013. This effect was consistent between sexes, schools, and day types (weekdays and weekend days. In addition, significant intervention effects were observed for vegetable consumption (0.83 servings.day-1, 95% CI: 0.24, 1.43, P = 0.007 and unhealthy food consumption (-0.56 servings.day-1, 95% CI: -1.05, -0.07, P = 0.027 on weekends but not weekdays, with no interactions with sex or school. Effects for all other variables were not statistically significant regardless of day type. Conclusions Compulsory health-related homework appears to be an effective approach for increasing physical activity and improving vegetable and unhealthy food consumption in children.

An Examination of the Associations between ADHD, Homework Behavior and Reading Comprehension
Little, Callie W.; Hart, Sara A.; Schatschneider, Christopher; Taylor, Jeanette
2015-01-01
Previous literature has indicated an important association between reading comprehension and both ADHD and homework habits. This investigation sought to extend previous knowledge by providing information about how ADHD and homework behavior (i.e., completing homework regularly) may jointly influence reading comprehension. Using a genetically sensitive design, this study examined the genetic and environmental influences on and between ADHD, homework behavior and reading comprehension. Participants for this study included 691 twin pairs (351 monozygotic, 340 same-sex dizygotic) from the Florida Twin Project on Behavior and Environment (FTP-BE) and 2647 twin pairs (865 monozygotic, 1782 dizygotic) from the larger Florida Twin Project on Reading (FTP-R) in grades 3 through 7. Three separate models, each representing a different definition of ADHD (full ADHD, Inattention only, and Hyperactivity/Impulsivity only), showed similar patterns of results, therefore, results of the full ADHD model are discussed. Overlapping genetic influences were found between ADHD, homework behavior and reading comprehension, but no shared environmental influences among all three. However, shared environmental influences overlapped between homework behavior and reading comprehension. Although the sources of this environmental overlap are unknown, these results have implications for improving homework practices and their subsequent influence on literacy skills through homework environments.

Insufficient sleep in school-aged children is common in modern society, with homework burden being a potential risk factor. The aim of this article is to explore the effect of sleep hygiene on the association between homework and sleep duration. Children filled out the Chinese version of the Adolescent Sleep Hygiene Scale, and parents filled out a sociodemographic questionnaire. The final sample included 363 boys and 371 girls with a mean age of 10.82 ± 0.38 years. Children with more homework went to bed later and slept less. Better sleep hygiene was associated with earlier bedtimes and longer sleep duration. Findings suggest that homework burden had a larger effect on sleep duration than sleep hygiene. Fifth-grade children in Shanghai have an excessive homework burden, which overwrites the benefit of sleep hygiene on sleep duration.

Full Text Available Students with Autism Spectrum Disorder often experience difficulty completing homework assignments independently more than students without disabilities. This study examined the use of a daily report card while adding a parent teacher component on the homework completion and accuracy rates of two second grade boys diagnosed with Autism. Parental participation for graphing and reviewing the student data involved the home environment. Researchers found that the use of the daily report card for homework completion and accuracy increased student success with the added parent teacher communication component. The parent teacher intervention increased both students’ homework completion by 65% and 38% respectively and accuracy rates by 123% and 30% respectively compared, to baseline sessions. Data showed that the addition of a parent teacher graphing component can be effective with a daily report card to increase parental involvement, while also helping increase homework completion and accuracy rates in students with Autism.
Homework setting in cognitive behavioral therapy: A study of discursive strategies.
Beckwith, Andrew; Crichton, Jonathan
2014-01-01
In recent years cognitive behavioral therapy (CBT), a form ofpsychotherapy, has risen to prominence due to a large number of studies attesting to its efficacy. A crucial part of the model of CBT is the use of the therapeutic strategy, homework, in which the client undertakes therapeutic tasks between sessions. The focus of this study is on how homework is implemented in sessions of CBT. This is undertaken through an analysis utilizing theme-orientated discourse analysis of video recorded sessions of CBT of one therapist and a client. Through tracking the focal theme of homework, the analysis focuses on homework as a face-threatening act (Brown and Levinson 1987) and how discursive strategies are employed to manage this issue. Other analytic themes include the use of frames (Goffman 1974) and constructed dialogue (Tannen 2007). It is the expertise of the therapist in putting into practice the therapeutic task of homework that is the subject of this study.

本文依据Goetz等人对作业情绪的研究方法，对某城市中学生在物理作业过程中表现出的愉快、自豪、担忧、生气、厌烦五种情绪进行调查研究。结果表明：（1）作业情绪和课堂情绪之间呈现显著相关，在学业情绪研究中有必要区分作业情绪和课堂情绪；（2）作业情绪和课堂情绪都与学业自我概念和学业成就之间成明显的相关性，两种情境下的情绪与学业成就的相关性相似；（3）与物理作业情绪间的关系相比，物理课堂情绪内部关系更加微弱。%Based on the research methods proposed by Goetz and others. The paper investigates the homework emotions of the students in a high school,namely their enjoyment,proudness,anxiety,anger,and boredom while completing physics homework ( homework emotions ). Results shows:1 ) homework emotions and classroom emotions are positively correlated and it is necessary to distinguish the two in academic emotions research;2 ) homework emotion and classroom emotion are relevant to academic self-concept and academic achievement;achievement relations are expected to be similar for class-related and homework emotions;and 3 )within-domain relations are weaker for classroom emotions as compared with homework emotions.
Connecting families and high schools through interactive homework
Pandya, Katrina
2008-10-01
The current study analyzed the effectiveness of integrating parents in the education of their children through interactive homework (IH). More specifically, the research questions of the study examined the effectiveness, feasibility, and usefulness of parental involvement in increasing academic performance within high school science classes. Using a mixed method design with a single IH treatment group, a convenience sample of 84 anatomy and biology students was assessed over a 6-week period. Although Spearman correlations failed to reveal any associations linking hours of parental IH involvement with student outcomes, related-samples t tests of pre/post student performance indicated significant increases in homework, test scores and overall grades, with greatest improvement observed in test scores. Exit questionnaires, focus groups, and interviews were coded for emergent themes that in turn were analyzed for common patterns. These qualitative data revealed positive feedback related to specific program components and a general interest for program continuation. The results indicated that it is possible to successfully incorporate parents at the high school level, even in technical subject areas. The research may be of particular interest to families and educators due to the positive scholastic effects of incorporating parents in high school academics. Social change is generated by incorporating parents into the educational process which strengthens the school-home bond and contributes to student achievement and motivation.
Using Peer Feedback to Promote Reflection on Open-Ended Problems
Reinholz, Daniel L
2016-01-01
This paper describes a new approach for learning from homework, called Peer-Assisted Reflection (PAR). PAR involves students using peer feedback to improve their work on open-ended homework problems. Collaborating with peers and revising one's work based on the feedback of others are important aspects of doing and learning physics. While notable exceptions exist, homework and exams are generally individual activities that do not support collaboration and refinement, which misses important opportunities to use assessment for learning. In contrast, PAR provides students with a structure to iteratively engage with challenging, open-ended problems and solicit the input of their peers to improve their work.

As part of an NSF-funded project, "CUES: Connecting Undergraduates to the Enterprise of Science," new inquiry-based homework materials were developed for two upper-level classes at the University of Missouri: Geochemistry (required for Geology majors, fulfills the computing requirement by having 50% of the grade come from five spreadsheet-based homework assignments), and Solar System Science (open to seniors and graduate students, co-taught and cross-listed between Geology and Physics & Astronomy). Inquiry involves activities where the learner engages in scientifically oriented questions, gives priority to evidence in responding to questions, formulates explanations from evidence, connects explanations to scientific knowledge, and communicates and justifies explanations. We engage students in inquiry-based learning by presenting homework exercises as "mini-journal" articles that follow the format of a scientific journal article, including a title, authors, abstract, introduction, methods, results, discussion and citations to peer-reviewed literature. The mini-journal provides a scaffold and serves as a springboard for students to develop and carry out their own follow-up investigation. They then present their findings in the form of their own mini-journal. Mini-journals replace traditional homework problem sets with a format that more directly reflects and encourages scientific practice. Students are engaged in inquiry-based homework which encompass doing, thinking, and communicating, while the mini-journal allows the instructor to contain lines of inquiry within the limits posed by available resources. In the examples we present, research is conducted via spreadsheet modeling, where the students develop their own spreadsheets. Example assignments from Geochemistry include "Trace Element Partitioning During Mantle Melting and MORB Crystallization" and "Isotopic Investigations of Crustal Evolution in the Midcontinent US". The key differences between the old and new

Enhancing therapeutic impact and therapeutic alliance through electronic mail homework assignments.
Murdoch, J W; Connor-Greene, P A
2000-01-01
Homework assignments can enhance therapeutic impact and increase therapy effectiveness by encouraging patients to focus on therapy-related issues between sessions. Computer technology provides a new avenue for reporting, monitoring, and feedback of patient homework assignments through electronic mail (e-mail). In two case examples, e-mail was used as an extension of therapy to enhance patient involvement in treatment. In both cases, patient reports suggest that therapeutic alliance and therapeutic impact improved with the use of e-mail homework reporting. The costs and benefits of the use of e-mail as an adjunct to therapy are discussed.
通过课外作业培养学生良好的学习习惯%Cultivating Students Study Habits through Homework
朱胜强

The survey shows that though students have developed good habits in math, they still have some bad habits. For example, they cannot insist on review their lessons before doing their homework; they cannot be careful enough when reading the problems; some lack of independent thinking when doing their homework; some don't reflect on their homework after doing it. Good habits come from persistence in the long run. Students have math homework almost every day. If teachers can give their full attention and purposely guide their students, they can help the students from good habits or get rid of existing bad ones, thus fulfill their duty as a math teacher in students' development.%学生在数学作业方面已经养成了许多好习惯，但也存在着一些不良习惯，如不能坚持先复习后作业，审题不仔细，作业时缺乏独立思考，不善于作业后进行反思等．良好习惯的养成贵在长期坚持．数学课外作业是学生几乎每天都有的学习任务，如果在此过程中教师能充分关注，有目的地引导，则一定有助于学生养成良好的学习习惯，纠正已有的不良习惯，充分发挥数学教育在发展人和完善人中的作用．

The Impact of Adding Online Homework Assignments to an Introduction to Physical Geology Class
Brevik, Eric C.
2017-04-01
As instructors we are constantly looking for ways to improve student performance in the classroom. In an attempt to improve student performance in my GEOL 105 - Introduction to Physical Geology class, I added online homework assignments from the Pearson Mastering Geology program beginning in the Fall semester of 2014. There were several anticipated advantages to the online homework approach. If a student is struggling with a question they can get hints that don't tell them the answer, but are designed to stimulate their thinking and lead them towards the correct answer. The students also know immediately after submitting their answers which questions they got right and which were wrong, and they can go back to the wrong answers and try to determine the correct answer so they know what it is. This gives them much more rapid feedback than traditional paper homework, all of which makes this a more student-centered approach to learning. It is also my hope that the students find the online homework more interesting and interactive than paper-based homework, which I hope in turn will stimulate the students to be more likely to do the homework and take it seriously while also having some fun while doing it. As of the end of Fall semester 2016, I had been using the online homework assignments in my classes for three years. Therefore, I analyzed student performance in the three years prior to adopting the online homework and compared it to performance over the three years since adopting online homework. In the three years prior to adopting the online homework, the average grade in my classes was 73.8%; afterwards the average grade was 81.3%, for an improvement of 7.5% on average. Most of that improvement was in average test scores, which increased by 6.3% (67.4% prior to 73.6% after). The online homework did not improve the performance of the top students, but it did improve the performance of the other students. Prior to adopting the online homework, grade distribution in

The successful implementation of mastery-style online homework into our preparatory mechanics course has been a long-term project, currently in its second year. By requiring students to perfect a single unit of defined competencies before moving on to its successive unit (with intervening narrated animated solutions for instructional support), this homework delivery method replaced traditional immediate feedback online homework for the class of about 500 students. After the first year of data collection and analysis, significant revisions were made to the system's delivery, content, and messaging. The impact of these changes and second year data will be presented, as well as data from implementation in our introductory electricity and magnetism course. NSF DUE 16-08002.

Although homework completion is said to be rather important to achievement, nowadays there is a growing concern of educators about the increasing number of students who do not engage properly on doing the homework tasks and the subsequent impact on school failure rates. Focusing on English as a Foreign Language (EFL) and using a sample of 591 Portuguese fifth and sixth graders, the present study analyses the role played by a number of homework variables on students' achievement (proximal and distal), and their mediating role on the use of self-regulated learning strategies and perceived self-efficacy in the domain. Data confirm the indirect effect of homework on school achievement, by means of the referred cognitive and motivational variables (use of self-regulated learning strategies and self-efficacy). These findings are further discussed in order to highlight the significant role homework completion can play on fighting school failure.

Homework in introductory physics represents an important part of a student's learning experience; therefore choosing the manner in which homework is presented merits investigation. We performed three rounds of clinical trials comparing the effects of mastery-style homework vs traditional-style homework with students in both algebra-based and calculus-based introductory mechanics. Results indicate a benefit from mastery-style over traditional-style homework, principally for weaker students who are less familiar with the material being covered and on questions that are nearer transfer to the study materials.

Research with substance-abusing samples suggests that eliciting commitment language during treatment may improve motivation to change, increase treatment engagement, and promote positive treatment outcomes. However, the relationship between in-session client language and treatment success is not well-understood for youth offender populations. This study evaluated the relationship between commitment language, treatment engagement (i.e., homework completion), and weekly employment outcomes for six gang-affiliated juvenile offenders participating in an employment counseling intervention. Weekly counseling sessions were audio-recorded, transcribed, and coded for commitment language strength. Multilevel models were fit to the data to examine the relationship between commitment language and counseling homework or employment outcomes within participants over time. Commitment language strength predicted subsequent homework completion but not weekly employment. These findings imply that gang-affiliated delinquent youth who express motivation to change during employment counseling will be more likely to comply with counselor-initiated homework. Further research on counselor techniques for promoting commitment language among juvenile gang offenders is needed.

Helping students learn effective problem solving strategies by reflecting with peers
Mason, Andrew
2016-01-01
We describe a study in which introductory physics students engage in reflection with peers about problem solving. The recitations for an introductory physics course with 200 students were broken into the "Peer Reflection" (PR) group and the traditional group. Each week in recitation, students in the PR group reflected in small teams on selected problems from the homework and discussed why solutions of some students employed better problem solving strategies than others. The graduate and undergraduate teaching assistants (TAs) in the PR group recitations provided guidance and coaching to help students learn effective problem solving heuristics. In the recitations for the traditional group, students had the opportunity to ask the graduate TA questions about the homework before they took a weekly quiz. The traditional group recitation quiz questions were similar to the homework questions selected for "peer reflection" in the PR group recitations. As one measure of the impact of this intervention, we investigated...

Assessing students' epistemic logic using clause topics during problem comparison
Mateycik, Fran; Sheaffer, Kendra
2013-01-01
Physics courses ideally facilitate both students understanding of fundamental physical principles, as well as strengthen students' problem solving repertoire. In this study we look at how students divide and/or aggregate various elements of problem statements and how useful distinct principles and concepts, formulae, and general problem contexts are for pairing problems assigned in the same week. Students in an algebra-based physics course were asked to choose two problems from each of their homework assignments which they found to be most similar. The two problems selected were then explicitly compared and contrasted in writing. The written statements were then divided by clause topics and further categorized into levels of epistemic reasoning. This paper presents the qualitative analysis used and provides observed trends that appear in students' homework responses.
A New Item Response Theory Model for Open-Ended Online Homework with Multiple Allowed Attempts
Gönülateş, Emre
2015-01-01
Item Response Theory (IRT) was originally developed in traditional exam settings, and it has been shown that the model does not readily transfer to formative assessment in the form of online homework. We investigate if this is mostly due to learner traits that do not become apparent in exam settings, namely random guessing due to lack of diligence or dedication, and copying work from other students or resources. Both of these traits mask the true ability of the learner, which is the only trait considered in most mainstream unidimensional IRT models. We find that indeed the introduction of these traits allows to better assess the true ability of the learners, as well as to better gauge the quality of assessment items. Correspondence of the model traits to self-reported behavior is investigated and confirmed. We find that of these two traits, copying answers has a larger influence on initial homework attempts than random guessing.

The benefits of effective parental involvement in education have been well documented and can be far reaching. When educators make an effort to involve families, parental involvement can be even more meaningful. Homework is a commonly practiced and accepted connection between school and home and affords parents many opportunities to interact with their children on educational endeavors. However, parental involvement may be limited because educators do not reach out to parents, parents feel their children do not need their help, or parents are unfamiliar with the content and therefore unable to help. The purpose of this study was too develop and implement a tool to enhance parental involvement and academic achievement of fourth grade science students. The tool used in this study was a weekly science video to be viewed by parents when it accompanied science homework assignments. To begin, the researcher created six science videos for parents to watch that supplemented weekly homework assignments. Consequently, the researcher set up treatment and comparison groups to test the effectiveness of the supplemental videos in terms of parental involvement and academic achievement. A mixed methods approach was used to collect data from parents and students throughout the study. A combination of quantitative and qualitative data was collected throughout this study from both parents and students. Additionally, data was collected from a variety of sources including baseline, midpoint, and endpoint surveys; scores on homework assignments; and focus group interview sessions with parents and students. Data analysis revealed an overall positive impact on parental involvement and academic achievement when the videos were utilized.

HOMEWORKING CONTRACT AND TELEWORKING - IMPORTANCE AND ROLE IN THE ECONOMY
OANA-CARMEN RĂVAŞ

Full Text Available Work at home leads to greater stability of the community, because changing jobs often lead to a change of life and inherent stress. Employers who choose to work at home do not have the problem of providing housing for service or cost they incurred directly or indirectly or through the gaining that lucrative acquire more space in the office or in premises whose owner is or the fact that there office rents. The individual contract of working at home is an individual employment contract named special character, with the main feature that "work place" is not located in the unit, the employer, but the employee's residence.

Activities designed to be performed outside of the intervention are considered an essential aspect of the effectiveness of cognitive-behavioral therapy. However, these have received little attention in interventions aimed at individuals with subclinical depressive symptoms who do not yet meet diagnostic criteria for depression (indicated prevention). In this study, the completion of tasks given as homework and their relationship with post-treatment depressive symptoms was with relation to an indicated prevention of depression intervention. Eighty-nine female non-professional caregivers recruited from an official registry completed an intervention involving 11 homework tasks. Tasks performed were recorded and depressive symptoms were assessed with the Center for Epidemiologic Studies Depression Scale (CES-D). Among caregivers, 80.9% completed 9-11 tasks. The number of tasks performed was associated with post-treatment depressive symptoms, with 9 being optimal for clinically significant improvement. These findings highlight the relationship between homework and post-treatment depressive symptoms.

Despite growing evidence that child welfare youth are at increased risk for juvenile delinquency, little is known about gender-specific processes and effective treatment programs for girls. Multidimensional Treatment Foster Care (MTFC), an empirically validated intervention for child welfare and juvenile justice populations, has demonstrated efficacy in reducing arrest rates in delinquent boys and girls. In this study, the efficacy of MTFC on school attendance and homework completion was examined in juvenile justice girls who were referred to out-of-home care (N = 81). Results from this randomized intervention trial suggest that MTFC was more effective than group care in increasing girls' school attendance and homework completion while in treatment and at 12 months postbaseline. In addition, the previously reported effect of MTFC on reducing girls' days in locked settings was mediated by homework completion while girls were enrolled in the intervention setting. Implications for policy and practice are described.

Full Text Available This paper explores the concept of parental involvement in English homework tasks as a way to include parents in the educational community. This descriptive study was carried out in a female public school with 10 students from third and fourth grades and their parents. In order to obtain the information, different instruments were used: artifacts, interviews, questionnaires and observations. After analyzing the data, it was stated that parental involvement was seen as a means to bridge the gap between the school and home. The findings also showed the possibility of learning from each other and the importance of homework tasks as interactional and learning spaces among parents and children. Key words: School and home connections, parental involvement in homework tasks Este artículo explora el concepto de la participación de los padres de familia en el desarrollo de las tareas de inglés, como una forma de incluir a los padres de familia en la comunidad educativa.

Homework is an important component of most physics courses. One of the functions it serves is to provide meaningful formative assessment in preparation for examinations. However, correlations between homework and examination scores tend to be low, likely due to unproductive student behavior such as copying and random guessing of answers. In this study, we attempt to model these two counterproductive learner behaviors within the framework of Item Response Theory in order to provide an ability measurement that strongly correlates with examination scores. We find that introducing additional item parameters leads to worse predictions of examination grades, while introducing additional learner traits is a more promising approach.

Historically, expectancy-value models of motivation assumed a synergistic relation between expectancy and value: motivation is high only when both expectancy and value are high. Motivational processes were studied from a within-person perspective, with expectancies and values being assessed or experimentally manipulated across multiple domains and the focus being placed on intraindividual differences. In contrast, contemporary expectancy-value models in educational psychology concentrate almost exclusively on linear effects of expectancy and value on motivational outcomes, with a focus on between-person differences. Recent advances in latent variable methodology allow both issues to be addressed in observational studies. Using the expectancy-value model of homework motivation as a theoretical framework, this study estimated multilevel structural equation models with latent interactions in a sample of 511 secondary school students and found synergistic effects between domain-specific homework expectancy and homework value in predicting homework engagement in 6 subjects. This approach not only brings the "×" back into expectancy-value theory but also reestablishes the within-person perspective as the appropriate level of analysis for latent expectancy-value models.

Although client-perceived therapist empathy relates to positive therapy outcomes, including in cognitive behavioral therapy (CBT), little is known about how empathy exerts its ameliorative effect. One possible way is by promoting clients' subsequent homework compliance, a variable that also predicts positive outcomes in CBT. The present study sought to investigate simultaneously, in the context of 43 therapist-client dyads receiving 15 sessions of CBT for generalized anxiety disorder, (1) the association of early client-perceived therapist empathy (averaged over sessions 1, 3, 5) with mid-treatment client homework compliance (averaged over sessions 6, 8, 10); (2) the association of mid-treatment homework compliance on client posttreatment worry severity; and (3) the indirect effect of early perceived therapist empathy on posttreatment worry through mid-treatment homework compliance. Given that clients were nested within therapists, we examined both within- and between-therapist differences in clients' ratings of therapist empathy and homework compliance, and tested both of these indices as predictors of the relevant dependent variables in a multilevel model. At the within-therapist level (i.e., differences between clients within a given therapist's caseload), greater early empathy was associated with greater mid-treatment homework compliance. At the between-therapist level (i.e., differences between therapists across all of their cases), greater between-therapist homework compliance was related to lower posttreatment worry. Finally, homework compliance was not found to mediate the relationship between empathy and posttreatment outcome. The results underscore the importance of parsing client and therapist effects, and are discussed with regard to their training and research implications.
Using Reflection with Peers to Help Students Learn Effective Problem Solving Strategies

2016-01-01
We describe a study in which introductory physics students engage in reflection with peers about problem solving. The recitations for an introductory physics course with 200 students were broken into the "Peer Reflection" (PR) group and the traditional group. Each week in recitation, students in the PR group reflected in small teams on selected problems from the homework. The graduate and undergraduate teaching assistants (TAs) in the PR group recitations provided guidance and coaching to help students learn effective problem solving heuristics. In the recitations for the traditional group, students had the opportunity to ask the graduate TA questions about the homework before they took a weekly quiz. On the final exam with only multiple-choice questions, the PR group drew diagrams on more problems than the traditional group, even when there was no external reward for doing so. Since there was no partial credit for drawing the diagrams on the scratch books, students did not draw diagrams simply to get credit ...

Prolonged exposure (PE) is an empirically supported treatment that is being disseminated broadly to providers in the Department of Veterans Affairs and Department of Defense. Innovative methods are needed to support the implementation, dissemination, and patient and provider adherence to PE. The PE Coach is a smartphone application (app) designed to mitigate barriers to PE implementation. PE Coach is installed on the patient's phone and includes a range of capabilities for use during the PE session and after each session to support the treatment. Functions include the ability to audio record treatment sessions onto the patient's device, to construct the in vivo hierarchy on the device, to record completed homework exercises, to review homework adherence, and to track symptom severity over time. The app also allows sessions and homework to be scheduled directly in the app, populating the device calendar with patient reminder notifications. In the final session, a visual display of symptom improvement and habituation to items on the in vivo hierarchy is presented. These capabilities may significantly improve convenience, provider implementation and adherence, and patient compliance with treatment. Future research is needed to test whether PE Coach is useful and effective.
Helping students learn effective problem solving strategies by reflecting with peers

We study how introductory physics students engage in reflection with peers about problem solving. The recitations for an introductory physics course with 200 students were broken into a "peer reflection" (PR) group and a traditional group. Each week in recitation, small teams of students in the PR group reflected on selected problems from the homework and discussed why the solutions of some students employed better problem solving strategies than others. The graduate and undergraduate teaching assistants in the PR recitations provided guidance and coaching to help students learn effective problem solving heuristics. In the traditional group recitations students could ask the graduate TA questions about the homework before they took a weekly quiz. The traditional group recitation quiz questions were similar to the homework questions selected for peer reflection in the PR group recitations. As one measure of the impact of this intervention, we investigated how likely students were to draw diagrams to help with problem solving on the final exam with only multiple-choice questions. We found that the PR group drew diagrams on more problems than the traditional group even when there was no explicit reward for doing so. Also, students who drew more diagrams for the multiple-choice questions outperformed those who did not, regardless of which group they were a member.

A brief historical research of homework in American around one hundred years is reviewed. This paper has divided the research into ifve time periods, which was the disregard in the late 19th century, followed by the criticism in the early 20th century, the reform and exploration against homework, the largely ignorance in the public view of the concerns, and the back to the view of concerns in the late 20th century and lfourished again. In these different stages, the researchers had studied the homework issues diligently, which had played an important role in guiding the homework policies for the United States and the formation and evolution of the different schools homework policies. At the same time, these studies on more than a century of research on homework also have important signiifcance and reference value for China homework research.%美国的家庭作业研究在近一百多年的时间里，历经了五个不同的历史阶段：从19世纪末的漠视、20世纪初的批判、而后的改革与探索、淡出大众视野到20世纪末的关注回归并重新兴盛。在这些不同的阶段中，研究者对家庭作业研究的孜孜探求，对于美国家庭作业相关政策及不同学校家庭作业制度的形成和演变起到了重要的指导作用。同时，这些研究对于我国家庭作业的研究也具有重要的借鉴和参考意义。
What Works for Parents: How Parents Support Their Children with Math Homework in Rural Ghana
Vivian Tackie-Ofosu

Full Text Available Family and Consumer Sciences (FCS programs target families in deprived rural and urban communities with the objective of equipping them with skills to improve family well-being, education, and relationships. In recent years, the focus of FCS in Ghana has been on parental styles and education that foster parents’ involvement in their children's school work. Using a child-parent interactive model, a series of math activities were delivered to children between the ages of 6 and 10 years. Group activities were also facilitated by the FCS staff. Parents used local materials, such as small empty cans, bottles, leaves, stones, sticks, old newspapers, and sand, to explain math concepts. Staff, parents, and children used fun activities and role plays to demonstrate developmental processes that enhance effective child development. The lessons identified were tied to the understanding of appropriate parenting styles that foster acquisition of skills for basic math concepts. At the end of the 12-week program, parents reported increased interest and confidence in math and were more proactive in supervising their children to complete their homework. The importance of the model lies in its simplicity in conveying fundamental knowledge that relates to the interwoven aspect of developmental domains to ensure children experience maximal success with math-related activities. The model also promotes acquisition of basic math skills in a naturalistic setting.

The aim of the study was to assess the extent to which the quality of group facilitation, group cohesion and the use of between session homework activities contribute to self-rated use of cognitive-behavioral skills amongst group participants. Participants attending SMART Recovery groups in Australia completed a cross sectional survey (N=124). The survey included measures of cognitive and behavioral skill utilization, group cohesion, quality of group facilitation and a rating of how frequently participants leave group meetings with an achievable between session homework plan. On average, participants had been attending SMART Recovery meetings for 9 months. Participants were most likely to attend SMART Recovery for problematic alcohol use. Regression analyses indicated that group cohesion significantly predicted use of cognitive restructuring, but that only provision of homework at the end of each group session predicted self-reported behavioral activation. Both group cohesion and leaving a group with an achievable homework plan predicted participant use of cognitive behavioral skills. The concrete actions associated with homework activities may facilitate behavioral activation. There is a need for longitudinal research to examine the relationship between the utilization of cognitive and behavioral skills and participant outcomes (e.g. substance use, mental health) for people attending SMART Recovery groups.

Students in a first-semester general chemistry course at a large southwestern university completed a 3-week homework assignment using MindTap, a Cengage Learning product. MindTap is the first major electronic system that has homework questions embedded in the text, such that students read a short section of the textbook and then answer a question set. Prior to MindTap, electronic homework systems were stand-alone or contained questions with links to the textbook. Next, students completed two 2-week homework assignments in Online Web Learning (OWL) version 1 also from Cengage Learning. The OWL system shows homework questions with a link to the textbook in a separate window. Both the MindTap and OWL systems contain the same or similar questions. After the students used both homework systems, a survey was given that included Likert-scaled and open-response questions that dealt with students' perceived level of understanding using the different systems, how easy the systems were to use, and the advantages/disadvantages of each system. A delayed survey was given at the end of the second semester of general chemistry, during which students had used OWL for the complete semester. This paper investigates the effects of the arrangement (embedded vs. linked) on student preferences and perceived learning in this pilot study with a 300-person class. Based on the results of the study, it was found that students perceived that they learn more with MindTap and prefer the embedded text in MindTap over the linked text in OWL.

Research into science identity, stereotype threat, and possible selves suggests a lack of diverse representations of scientists could impede traditionally underserved students from persisting and succeeding in science. We evaluated a series of metacognitive homework assignments (“Scientist Spotlights”) that featured counterstereotypical examples of scientists in an introductory biology class at a diverse community college. Scientist Spotlights additionally served as tools for content coverage, as scientists were selected to match topics covered each week. We analyzed beginning- and end-of-course essays completed by students during each of five courses with Scientist Spotlights and two courses with equivalent homework assignments that lacked connections to the stories of diverse scientists. Students completing Scientist Spotlights shifted toward counterstereotypical descriptions of scientists and conveyed an enhanced ability to personally relate to scientists following the intervention. Longitudinal data suggested these shifts were maintained 6 months after the completion of the course. Analyses further uncovered correlations between these shifts, interest in science, and course grades. As Scientist Spotlights require very little class time and complement existing curricula, they represent a promising tool for enhancing science identity, shifting stereotypes, and connecting content to issues of equity and diversity in a broad range of STEM classrooms.

We report on the use of qualitative problem-solving strategies in teaching an introductory, calculus-based physics course as a means of highlighting the role played by conceptual knowledge in solving problems. We found that presenting strategies during lectures and in homework solutions provides an excellent opportunity to model for students the type of concept-based, qualitative reasoning that is valued in our profession, and that student-generated strategies serve a diagnostic function by providing instructors with insights on students' conceptual understanding and reasoning. Finally, we found strategies to be effective pedagogical tools for helping students both to identify principles that could be applied to solve specific problems, as well as to recall the major principles covered in the course months after it was over.

Microcomputer-based laboratories (MBLs) have been defined as software that uses an electronic probe to collect information about a physical system and then converts that information into graphical systems in real-time. Realtime Physics Laboratories (RTP) are an example of laboratories that combine the use of MBLs with collaboration and guided-inquiry. RTP Mechanics Laboratories include both laboratory activities and laboratory homework for the first semester of college freshman physics courses. Prior research has investigated the effectiveness of the RTP laboratories as a package (laboratory activities with laboratory homework). In this study, an experimental-treatment had students complete both the RTP laboratory activity and the associated laboratory homework during the same laboratory period. Observations of this treatment indicated that students primarily consulted the laboratory instructor and referred to their completed laboratory activity while completing the homework in their collaborative groups. In the control-treatment, students completed the laboratory homework outside the laboratory period. Measures of force and motion conceptual understanding included the Force and Motion Conceptual Understanding (FMCE), a 47 multiple-choice question test. Analyses of the FMCE indicated that it is both a reliable and a valid measure of force and motion conceptual understanding. A distinct, five-factor structure for the FMCE post-test answers reflected specific concepts related to force and motion. However, the three FMCE pretest factors were less distinct. Analysis of the experimental-treatment, compared to a control-treatment, included multiple regression analysis with covariates of age, prior physics-classroom experience, and the three FMCE pretest factors. Criterion variables included each of the five post-test factors, the total laboratory homework score, and a group of seven exam questions. The results were all positive, in favor of the experimental
Group Problem Solving as a Zone of Proximal Development activity
Brewe, Eric
2006-12-01
Vygotsky described learning as a process, intertwined with development, which is strongly influenced by social interactions with others that are at differing developmental stages.i These interactions create a Zone of Proximal Development for each member of the interaction. Vygotsky’s notion of social constructivism is not only a theory of learning, but also of development. While teaching introductory physics in an interactive format, I have found manifestations of Vygotsky’s theory in my classroom. The source of evidence is a paired problem solution. A standard mechanics problem was solved by students in two classes as a homework assignment. Students handed in the homework and then solved the same problem in small groups. The solutions to both the group and individual problem were assessed by multiple reviewers. In many cases the group score was the same as the highest individual score in the group, but in some cases, the group score was higher than any individual score. For this poster, I will analyze the individual and group scores and focus on three groups solutions and video that provide evidence of learning through membership in a Zone of Proximal Development.

Using Reflection with Peers to Help Students Learn Effective Problem Solving Strategies
Mason, Andrew; Singh, Chandralekha
2010-10-01
We describe a study in which introductory physics students engage in reflection with peers about problem solving. The recitations for an introductory physics course with 200 students were broken into the "Peer Reflection" (PR) group and the traditional group. Each week in recitation, students in the PR group reflected in small teams on selected problems from the homework. The graduate and undergraduate teaching assistants (TAs) in the PR group recitations provided guidance and coaching to help students learn effective problem solving heuristics. In the recitations for the traditional group, students had the opportunity to ask the graduate TA questions about the homework before they took a weekly quiz. On the final exam with only multiple-choice questions, the PR group drew diagrams on more problems than the traditional group, even when there was no external reward for doing so. Since there was no partial credit for drawing the diagrams on the scratch books, students did not draw diagrams simply to get credit for the effort shown and must value the use of diagrams for solving problems if they drew them. We also find that, regardless of whether the students belonged to the traditional or PR groups, those who drew more diagrams for the multiple-choice questions outperformed those who did not draw them.

A Flipped Pedagogy for Expert Problem Solving
Pritchard, David
The internet provides free learning opportunities for declarative (Wikipedia, YouTube) and procedural (Kahn Academy, MOOCs) knowledge, challenging colleges to provide learning at a higher cognitive level. Our ``Modeling Applied to Problem Solving'' pedagogy for Newtonian Mechanics imparts strategic knowledge - how to systematically determine which concepts to apply and why. Declarative and procedural knowledge is learned online before class via an e-text, checkpoint questions, and homework on edX.org (see http://relate.mit.edu/physicscourse); it is organized into five Core Models. Instructors then coach students on simple ``touchstone problems'', novel exercises, and multi-concept problems - meanwhile exercising three of the four C's: communication, collaboration, critical thinking and problem solving. Students showed 1.2 standard deviations improvement on the MIT final exam after three weeks instruction, a significant positive shift in 7 of the 9 categories in the CLASS, and their grades improved by 0.5 standard deviation in their following physics course (Electricity and Magnetism).

This trial compared two approaches used to introduce parenting skills in a residential staff training program. Fifty staff were randomly assigned to: mastery modelling in which videotaped models demonstrated new skills, coping modelling problem solving (CMPS) in which participants formulated their own solutions to the errors depicted by videotaped models, or a waiting-list control group. In both, leaders used modelling, role playing, and homework projects to promote mastery and transfer of new skills. The skills of all groups improved, but CMPS participants attended more sessions, were late to fewer sessions, completed more homework, engaged in more cooperative in-session interaction, rated the program more positively, and reported higher job accomplishment scores. These data suggest that CMPS allowing participants to formulate their own solutions may enhance adherence and reduce the resistance observed in more didactic programs.

Using the auxiliary principle technique, we suggest and analyze a class of iterative algorithms for solving hemiequilibrium problems, the convergence of which requires either pseudomonotonicity or partially relaxed strong monotonicity. As a special case, we obtain a new method for hemivariational inequalities. Since hemiequilibrium problems include hemivariational inequalities and equilibrium problems as special cases, the results proved in this paper still hold for these problems.

Full Text Available Abstract Background Little information exists on work and stress related health of medical doctors in non-EU countries. Filling this knowledge gap is needed to uncover the needs of this target population and to provide information on comparability of health related phenomena such as burnout across countries. This study examined work related characteristics, work-home and home-work interference and burnout among Serbian primary healthcare physicians (PHPs and compared burnout levels with other medical doctors in EU countries. Methods Data were collected via surveys which contained Maslach Burnout Inventory and other validated instruments measuring work and home related characteristics. The sample consisted of 373 PHPs working in 12 primary healthcare centres. Data were analysed using t-tests and Chi square tests. Results No gender differences were detected on mean scores of variables among Serbian physicians, who experience high levels of personal accomplishment, workload, job control and social support, medium to high levels of emotional exhaustion, medium levels of depersonalisation and work-home interference, and low levels of home-work interference. There were more women than men who experienced low job control and high depersonalisation. Serbian physicians experienced significantly higher emotional exhaustion and lower depersonalisation than physicians in some other European countries. Conclusions To diminish excessive workload, the number of physicians working in primary healthcare centres in Serbia should be increased. Considering that differences between countries were detected on all burnout subcomponents, work-related interventions for employees should be country specific. The role of gender needs to be closely examined in future studies as well.
Web-Based Problem-Solving Assignment and Grading System
Brereton, Giles; Rosenberg, Ronald
2014-11-01
In engineering courses with very specific learning objectives, such as fluid mechanics and thermodynamics, it is conventional to reinforce concepts and principles with problem-solving assignments and to measure success in problem solving as an indicator of student achievement. While the modern-day ease of copying and searching for online solutions can undermine the value of traditional assignments, web-based technologies also provide opportunities to generate individualized well-posed problems with an infinite number of different combinations of initial/final/boundary conditions, so that the probability of any two students being assigned identical problems in a course is vanishingly small. Such problems can be designed and programmed to be: single or multiple-step, self-grading, allow students single or multiple attempts; provide feedback when incorrect; selectable according to difficulty; incorporated within gaming packages; etc. In this talk, we discuss the use of a homework/exam generating program of this kind in a single-semester course, within a web-based client-server system that ensures secure operation.

Disruptive behavior disorders (DBDs) (oppositional defiant disorder (ODD) and conduct disorder (CD)) are prevalent, costly, and oftentimes chronic psychiatric disorders of childhood. Evidence-based interventions that focus on assisting parents to utilize effective skills to modify children's problematic behaviors are first-line interventions for the treatment of DBDs. Although efficacious, the effects of these interventions are often attenuated by poor implementation of the skills learned during treatment by parents, often referred to as between-session homework. The multiple family group (MFG) model is an evidence-based, skills-based intervention model for the treatment of DBDs in school-age youth residing in urban, socio-economically disadvantaged communities. While data suggest benefits of MFG on DBD behaviors, similar to other skill-based interventions, the effects of MFG are mitigated by the poor homework implementation, despite considerable efforts to support parents in homework implementation. This paper focuses on the study protocol for the development and preliminary evaluation of a theory-based, smartphone mobile health (mHealth) application (My MFG) to support homework implementation by parents participating in MFG. This paper describes a study design proposal that begins with a theoretical model, uses iterative design processes to develop My MFG to support homework implementation in MFG through a series of pilot studies, and a small-scale pilot randomised controlled trial to determine if the intervention can demonstrate change (preliminary efficacy) of My MFG in outpatient mental health settings in socioeconomically disadvantaged communities. This preliminary study aims to understand the implementation of mHealth methods to improve the effectiveness of evidence-based interventions in routine outpatient mental health care settings for youth with disruptive behavior and their families.

Degarmo, David S; Chamberlain, Patricia; Leve, Leslie D; Price, Joe
2009-07-01
OBJECTIVE: The authors conduct a within intervention group analysis to test whether caregiver engagement (e.g., participation, homework completion, openness to ideas, apparent satisfaction) in a group-based intervention moderates risk factors for foster child outcomes in a state-supported randomized trial of caregiver parent training. METHODS: The intervention is delivered in 16 weekly sessions by trained leaders. Outcomes are pre-post change in problem behaviors and negative placements. RESULTS: Analysis of 337 caregivers nested within 59 parent groups show caregiver engagement moderates number of prior placements on increases in child problem behaviors, and moderates risk of negative placement disruption for Hispanics. CONCLUSIONS: Variance in parent group process affects program effectiveness. Implications for practice and increasing effective engagement are discussed.

Thirteen years have passed since the seminal book on knapsack problems by Martello and Toth appeared. On this occasion a former colleague exclaimed back in 1990: "How can you write 250 pages on the knapsack problem?" Indeed, the definition of the knapsack problem is easily understood even by a non-expert who will not suspect the presence of challenging research topics in this area at the first glance. However, in the last decade a large number of research publications contributed new results for the knapsack problem in all areas of interest such as exact algorithms, heuristics and approximation schemes. Moreover, the extension of the knapsack problem to higher dimensions both in the number of constraints and in the num ber of knapsacks, as well as the modification of the problem structure concerning the available item set and the objective function, leads to a number of interesting variations of practical relevance which were the subject of intensive research during the last few years. Hence, two years ago ...

This book, intended as a practical working guide for students in Engineering, Mathematics, Physics, or any other field where rigorous calculus is needed, includes 450 exercises. Each chapter starts with a summary of the main definitions and results, which is followed by a selection of solved exercises accompanied by brief, illustrative comments. A selection of problems with indicated solutions rounds out each chapter. A final chapter explores problems that are not designed with a single issue in mind but instead call for the combination of a variety of techniques, rounding out the book’s coverage. Though the book’s primary focus is on functions of one real variable, basic ordinary differential equations (separation of variables, linear first order and constant coefficients ODEs) are also discussed. The material is taken from actual written tests that have been delivered at the Engineering School of the University of Genoa. Literally thousands of students have worked on these problems, ensuring their real-...

the nonsmooth convex optimization problem. First, by using Moreau-Yosida regularization, we convert the original objective function to a continuously differentiable function; then we use approximate function and gradient values of the Moreau-Yosida regularization to substitute the corresponding exact values in the algorithm. The global convergence is proved under suitable assumptions. Numerical experiments are presented to show the effectiveness of this algorithm.

Full Text Available This paper investigates the Lipschitz continuity of the solution mapping of symmetric cone (linear or nonlinear complementarity problems (SCLCP or SCCP, resp. over Euclidean Jordan algebras. We show that if the transformation has uniform Cartesian P-property, then the solution mapping of the SCCP is Lipschitz continuous. Moreover, we establish that the monotonicity of mapping and the Lipschitz continuity of solutions of the SCLCP imply ultra P-property, which is a concept recently developed for linear transformations on Euclidean Jordan algebra. For a Lyapunov transformation, we prove that the strong monotonicity property, the ultra P-property, the Cartesian P-property, and the Lipschitz continuity of the solutions are all equivalent to each other.

针对日益严重的电子作业抄袭现象,在分析目前的电子作业抄袭检测系统无法将抄袭作业拒绝于提交之前等问题的基础上,阐述了一套基于空间向量模型TF-IDF方法的电子作业反抄袭系统.该系统在对电子作业进行分词的基础上,使用空间向量模型的TF-IDF方法计算文本相似度,并依据相似度判断电子作业是否有抄袭行为.为了解决因短时间内大量的电子作业提交而导致系统崩溃,系统使用MSMQ建立电子作业提交队列,同时,系统还提供了电子作业评阅及系统设置等功能.系统使用时间优先策略来认定抄袭作业,有效地从抄袭者和被抄袭者上杜绝了抄袭行为.%To solve the issue of increasingly severe e-homework plagiarism, an anti-plagiarism system of e-homework based on the vector space model (VSM) and TF-IDF is given, after the analysis of current counterparts systems. Similarity is calculated by VSM theory and TF-IDF after the segmentation of the e-homework, and plagiarism is decided by the similarity. Microsoft Message Queue (MSMQ) is used to relieve the stress of the system, and e-homework and system configuration functions are supported. Also time preference tragedy is used. And it can validly avoid the plagiarism from both copycat and the source.

The existing literature indicates that interactive-engagement (IE) based general physics classes improve conceptual learning relative to more traditional lecture-oriented classrooms. Very little research, however, has examined quantitative problem-solving outcomes from IE based relative to traditional lecture-based physics classes. The present study included both pre- and post-course conceptual-learning assessments and a new quantitative physics problem-solving assessment that included three representative conservation of energy problems from a first-semester calculus-based college physics course. Scores for problem translation, plan coherence, solution execution, and evaluation of solution plausibility were extracted for each problem. Over 450 students in three IE-based sections and two traditional lecture sections taught at the same university during the same semester participated. As expected, the IE-based course produced more robust gains on a Force Concept Inventory than did the lecture course. By contrast, when the full sample was considered, gains in quantitative problem solving were significantly greater for lecture than IE-based physics; when students were matched on pre-test scores, there was still no advantage for IE-based physics on gains in quantitative problem solving. Further, the association between performance on the concept inventory and quantitative problem solving was minimal. These results highlight that improved conceptual understanding does not necessarily support improved quantitative physics problem solving, and that the instructional method appears to have less bearing on gains in quantitative problem solving than does the kinds of problems emphasized in the courses and homework and the overlap of these problems to those on the assessment.

This paper presents a new method and a constraint-based objective function to solve two problems related to the design of optical telecommunication networks, namely the Synchronous Optical Network Ring Assignment Problem (SRAP) and the Intra-ring Synchronous Optical Network Design Problem (IDP). These network topology problems can be represented as a graph partitioning with capacity constraints as shown in previous works. We present here a new objective function and a new local search algorithm to solve these problems. Experiments conducted in Comet allow us to compare our method to previous ones and show that we obtain better results.

The algebraic path problem is a generalization of the shortest path problem in graphs. Various instances of this abstract problem have appeared in the literature, and similar solutions have been independently discovered and rediscovered. The repeated appearance of a problem is evidence of its relevance. This book aims to help current and future researchers add this powerful tool to their arsenal, so that they can easily identify and use it in their own work. Path problems in networks can be conceptually divided into two parts: A distillation of the extensive theory behind the algebraic path pr

Psychologists have long known that an expert in a field not only knows significantly more individual facts/skills than a novice but also has these facts/skills organized into a mental hierarchy that links the individual facts (at the bottom of the hierarchy) together with larger more-encompassing ideas (at the top of the hierarchy). In the Spring quarter of 2012, UC Davis offered 4 sections (about 180 students each) of the first quarter of introductory physics, Physics 9A, covering Newtonian mechanics. One of these sections is a "treatment" group and had the entire 10-week quarter's set of ideas introduced, largely qualitatively, in the first 6 weeks followed by the 4 weeks where students learn to use those ideas to solve the algebraically complicated problems that physicists prize. The other three sections were organized as usual. The treatment group and one of the other sections were taught by the author and were identical (same homework, discussion, lecture, and lab) except for the organization of the cont...
Using Problem-Based Learning to help Portuguese students make the Bologna transition

Full Text Available The Bologna Declaration has opened a stage of big and deep changes in the internal university organization, external cooperation, teaching models and methods, among other., all over the European countries. Here we will present and discuss a pilot experience conducted at the Engineering Department of the University of Trás-os-Montes e Alto Douro, Portugal, during the second year of that transition period. In brief, we will present a set of non-mandatory courses proposed to the students of each individual syllabus, with one hundred hours duration, each, approximately seven hours/week, fifteen weeks long, with the permanent help of a specialized trainer to aid the students in their "homework". The formal bureaucratic transition is also presented. Design and implementation issues, supported on problem-based learning and experimental lab learning classes, final assessment results, as well as the opinion of the students, are presented and analyzed. We believe that this methodology helped to make the transition smoother to the students, but also to the teaching staff.

In the matrix interdiction problem, a real-valued matrix and an integer k is given. The objective is to remove k columns such that the sum over all rows of the maximum entry in each row is minimized. This combinatorial problem is closely related to bipartite network interdiction problem which can be applied to prioritize the border checkpoints in order to minimize the probability that an adversary can successfully cross the border. After introducing the matrix interdiction problem, we will prove the problem is NP-hard, and even NP-hard to approximate with an additive n{gamma} factor for a fixed constant {gamma}. We also present an algorithm for this problem that achieves a factor of (n-k) mUltiplicative approximation ratio.
The Accelerated Kepler Problem
Namouni, Fathi
2007-01-01
The accelerated Kepler problem is obtained by adding a constant acceleration to the classical two-body Kepler problem. This setting models the dynamics of a jet-sustaining accretion disk and its content of forming planets as the disk loses linear momentum through the asymmetric jet-counterjet system it powers. The dynamics of the accelerated Kepler problem is analyzed using physical as well as parabolic coordinates. The latter naturally separate the problem's Hamiltonian into two unidimensional Hamiltonians. In particular, we identify the origin of the secular resonance in the accelerated Kepler problem and determine analytically the radius of stability boundary of initially circular orbits that are of particular interest to the problem of radial migration in binary systems as well as to the truncation of accretion disks through stellar jet acceleration.

Full Text Available The author explains the link between fundamental ontology and metontology in Heidegger's thought. In this context, he raises the question about art as a metontological problem. Then he goes to show that the problem of metontology stems from imanent transformation of fundamental ontology. In this sense, two aspects of the problem of existence assume relevance, namely, universality and radicalism. He draws the conclusion that metontology and art as its problem, as opposed to fundamental ontology, were not integrated into Heidegger's later thought.

This memo catalogs a number of known TCP implementation problems. The goal in doing so is to improve conditions in the existing Internet by enhancing the quality of current TCP/IP implementations. It is hoped that both performance and correctness issues can be resolved by making implementors aware of the problems and their solutions. In the long term, it is hoped that this will provide a reduction in unnecessary traffic on the network, the rate of connection failures due to protocol errors, and load on network servers due to time spent processing both unsuccessful connections and retransmitted data. This will help to ensure the stability of the global Internet. Each problem is defined as follows: Name of Problem The name associated with the problem. In this memo, the name is given as a subsection heading. Classification one or more problem categories for which the problem is classified: "congestion control", "performance", "reliability", "resource management". Description A definition of the problem, succinct but including necessary background material. Significance A brief summary of the sorts of environments for which the problem is significant.

Location-routing problems involve simultaneously locating a number of facilities among candidate sites and establishing delivery routes to a set of users in such a way that the total system cost is minimized. This paper presents a survey of such problems. It includes some applications and examples of location-routing problems, a description of the main heuristics that have been developed for such problems, and reviews of various formulations and algorithms used in solving these problems. A more detailed review is given of exact algorithms for the vehicle routing problem, three-index vehicle flow formulations, and two-index vehicle flow formulations and algorithms for symmetrical and non-symmetrical problems. It is concluded that location-routing problem research is a fast-growing area, with most developments occurring over the past few years; however, research is relatively fragmented, often addresses problems which are too specific and contains several voids which have yet to be filled. A number of promising research areas are identified. 137 refs., 3 figs.

As part of weekly reports,1 structured journals in which students answer three standard questions each week, they respond to the prompt, If I were the instructor, what questions would I ask or problems assign to determine if my students understood the material? An initial analysis of the results shows that some student-generated problems indicate fundamental misunderstandings of basic physical concepts. A further investigation explores the relevance of the problems to the week's material, whether the problems are solvable, and the type of problems (conceptual or calculation-based) written. Also, possible links between various characteristics of the problems and conceptual achievement are being explored. The results of this study spark many more questions for further work. A summary of current findings will be presented, along with its relationship to previous work concerning problem posing.2 1Etkina, E.

Problems in equilibrium theory
Aliprantis, Charalambos D
1996-01-01
In studying General Equilibrium Theory the student must master first the theory and then apply it to solve problems. At the graduate level there is no book devoted exclusively to teaching problem solving. This book teaches for the first time the basic methods of proof and problem solving in General Equilibrium Theory. The problems cover the entire spectrum of difficulty; some are routine, some require a good grasp of the material involved, and some are exceptionally challenging. The book presents complete solutions to two hundred problems. In searching for the basic required techniques, the student will find a wealth of new material incorporated into the solutions. The student is challenged to produce solutions which are different from the ones presented in the book.

The synchronizing word of deterministic automaton is a word in the alphabet of colors (considered as letters) of its edges that maps the automaton to a single state. A coloring of edges of a directed graph is synchronizing if the coloring turns the graph into deterministic finite automaton possessing a synchronizing word. The road coloring problem is a problem of synchronizing coloring of directed finite strongly connected graph with constant outdegree of all its vertices if the greatest common divisor of lengths of all its cycles is one. The problem was posed by Adler, Goodwyn and Weiss over 30 years ago and evoked a noticeable interest among the specialists in theory of graphs, deterministic automata and symbolic dynamics. The problem is described even in "Vikipedia" - the popular Internet Encyclopedia. The positive solution of the road coloring problem is presented.
The Guderley problem revisited

2009-01-01
The self-similar converging-diverging shock wave problem introduced by Guderley in 1942 has been the source of numerous investigations since its publication. In this paper, we review the simplifications and group invariance properties that lead to a self-similar formulation of this problem from the compressible flow equations for a polytropic gas. The complete solution to the self-similar problem reduces to two coupled nonlinear eigenvalue problems: the eigenvalue of the first is the so-called similarity exponent for the converging flow, and that of the second is a trajectory multiplier for the diverging regime. We provide a clear exposition concerning the reflected shock configuration. Additionally, we introduce a new approximation for the similarity exponent, which we compare with other estimates and numerically computed values. Lastly, we use the Guderley problem as the basis of a quantitative verification analysis of a cell-centered, finite volume, Eulerian compressible flow algorithm.

Full Text Available The process of making complex and controversial decisions, that is, dealing with moral or ethical dilemmas, have intrigued people and inspired writers from time immemorial. Dilemmas give both color and depth to characters in good literary works. But beyond literary fiction, dilemmas occupy society in every day issues such as in introducing legislation or solving current political problems. One example of a current political dilemma is how to deal with Iran’s quest for nuclear weapons. If it were possible to assess and quantify each of the alternative solutions for a given problem, the process of decision making would be much easier. If a problem involves only two optional solutions, game theory techniques can be used. However, real life problems are usually multi-unit, multi-optional problems, as in Iran

Recently, there has been much interest in spectral approaches to learning manifolds---so-called kernel eigenmap methods. These methods have had some successes, but their applicability is limited because they are not robust to noise. To address this limitation, we look at two-manifold problems, in which we simultaneously reconstruct two related manifolds, each representing a different view of the same data. By solving these interconnected learning problems together and allowing information to flow between them, two-manifold algorithms are able to succeed where a non-integrated approach would fail: each view allows us to suppress noise in the other, reducing bias in the same way that an instrumental variable allows us to remove bias in a {linear} dimensionality reduction problem. We propose a class of algorithms for two-manifold problems, based on spectral decomposition of cross-covariance operators in Hilbert space. Finally, we discuss situations where two-manifold problems are useful, and demonstrate that sol...

For a given set of intervals on the real line, we consider the problem of ordering the intervals with the goal of minimizing an objective function that depends on the exposed interval pieces (that is, the pieces that are not covered by earlier intervals in the ordering). This problem is motivated by an application in molecular biology that concerns the determination of the structure of the backbone of a protein. We present polynomial-time algorithms for several natural special cases of the problem that cover the situation where the interval boundaries are agreeably ordered and the situation where the interval set is laminar. Also the bottleneck variant of the problem is shown to be solvable in polynomial time. Finally we prove that the general problem is NP-hard, and that the existence of a constant-factor-approximation algorithm is unlikely.

For the structural problems, which could be represented by means of the mathematical modelling of the finite element code discussed method is extremely useful. The nonlinear minimization problem of the L2 norm for the structures with linear elastic behaviour is solved by using of the Optimization Toolbox of Matlab. The direct and inverse procedures for the composition of the desired function to minimize are illustrated for the spatial 3D truss structure as well as for the problem of plane finite elements. The truss identification problem is solved with 2 and 3 unknown parameters in order to compare the computational efforts and for the graphical purposes. The particular commands of the Matlab codes are present in this paper.

Based upon the research to the economic equilibrium problems, we present a kind of new mathematical programming problem-interaction programming problem (abbreviated by IPP). The IPP is composed of two or multiple parametric programming problems which is interrelated with each other. The IPP reflects the equality and mutual benefit relationship between two (or among multiple) economic planners in an economic system. In essence, the IPP is similar to the generalized Nash equilibria (GNE) game which has been given several names in the literature: social equilibria games, pseudo-Nash equilibria games, and equilibrium programming problems. In this paper, we establish the mathematical model and some basic concepts to the IPP. We investigate the structure and the properties of the IPP. We also give a necessary and sufficient conditions for the existence of the equilibrium points to a kind of linear IPP.

One finding of cognitive research is that people do not automatically acquire usable knowledge by spending lots of time on task. Because students' knowledge hierarchy is more fragmented, "knowledge chunks" are smaller than those of experts. The limited capacity of short term memory makes the cognitive load high during problem solving tasks, leaving few cognitive resources available for metacognition. The abstract nature of the laws of physics and the chain of reasoning required to draw meaningful inferences makes these issues critical. In order to help students, it is crucial to consider the difficulty of a problem from the perspective of students. We are developing and evaluating interactive problem-solving tutorials to help students in the introductory physics courses learn effective problem-solving strategies while solidifying physics concepts. The self-paced tutorials can provide guidance and support for a variety of problem solving techniques, and opportunity for knowledge and skill acquisition.

This paper investigates the origin of compensation for homework on divorce in terms of the appraisal datum of homework, and discovers that there is no certain relevance between the two and it is no need to conform. In applying Article 40 Marriage Law, we should tell separate jurisdiction and community property apart, but it is just effect factor of the economic compensation amount.

Generalized emissivity inverse problem.

2002-04-01
Inverse problems have recently drawn considerable attention from the physics community due to of potential widespread applications [K. Chadan and P. C. Sabatier, Inverse Problems in Quantum Scattering Theory, 2nd ed. (Springer Verlag, Berlin, 1989)]. An inverse emissivity problem that determines the emissivity g(nu) from measurements of only the total radiated power J(T) has recently been studied [Tao Wen, DengMing Ming, Xianxi Dai, Jixin Dai, and William E. Evenson, Phys. Rev. E 63, 045601(R) (2001)]. In this paper, a new type of generalized emissivity and transmissivity inverse (GETI) problem is proposed. The present problem differs from our previous work on inverse problems by allowing the unknown (emissivity) function g(nu) to be temperature dependent as well as frequency dependent. Based on published experimental information, we have developed an exact solution formula for this GETI problem. A universal function set suggested for numerical calculation is shown to be robust, making this inversion method practical and convenient for realistic calculations.

Divers can have several oral problems. Firstly, problems caused by pressure changes. These are barodontalgia and odontocrexis. Barodontalgia is toothache by barotrauma. Odontocrexis is restorations coming lose or breaking or tooth fractures by expansion of air beneath restorations. Other problems can occur by cements used to fix casted restorations, by inflammations in the orofacial region, and by not yet fully healed oral wounds. Secondly, there are problems related to the diver's mouthpiece. To keep the mouthpiece in place, the mandible has to be forced in a forward position. Holding this position often and for long periods of time, may develop or aggravate temporomandibular dysfunction. Insufficient fit of the mouthpiece may induce oral mucosal lesions. Therefore, it is recommended to produce individual diver mouthpieces. It is also recommended to produce individual diver mouthpieces for complete dentures wearing divers and for divers with fixed orthodontic appliances.

This didactic paper is motivated by the problem of understanding how stars escape from globular star clusters. One formulation of this problem is known, in dynamical astronomy, as Hill's problem. Originally intended as a model for the motion of the moon around the earth with perturbations by the sun, with simple modifications it also serves as a model for the motion of a star in a star cluster with perturbations by the galaxy. The paper includes introductory sections on the derivation of the equations of motion of Hill's problem, their elementary properties, and extensions to deal with non-point masses and non-circular orbits. We then show how the rate of escape may be calculated numerically and estimated theoretically, and discuss how this simple picture is modified if the stars in a cluster are also undergoing two-body relaxation. Finally we introduce some established ideas for obtaining the distribution of escape times.

Full Text Available In this current work, I am proposing a general close examination of Problem Based Learning as a student centered educational method in which a problem constitutes the starting point of the learning process. Such a method provides students with the suitable knowledge for problem solving and presents numerous and significant differences compared to traditional education.In particular, I analyze the theoretic aspects of problem learning by tracing a history and presenting its structure, clarifying the role of the tutor in the various phases of the learning process. The method has found a wide diffusion since the beginning of the 70s and numerous studies have confirmed the advantages. The effectiveness of PBL is construable and is based on principles of constructivism and cognitivism.

In a time of increasing globalisation and urbanisation, shrinking peripheral rural areas have become a truly wicked planning problem in many European countries. Although a problem can be easily perceived and measured by various indicators, the precise definition of the problem is problematic. Based...... on the case of a Danish planning process which was carried out in collaboration with a charitable trust, this paper discusses an emerging strategic planning approach at the municipal level. We use the concept of wicked problems, strategic planning theory and Actor-Network-Theory to study a collaborative......, place-based and project-oriented process directed at concrete physical outcomes. We frame strategic planning as a translation process where the interaction between human and non-human actors translates a unique, complex and contested situation into an innovated situation. We find that local physical...

Full Text Available Framing ‘science and society’ as a conflict has diverted us from more important problems. Our economic environment urges the commercialisation and social acceptance of new technologies, and science communicators and their publics contribute work to these ends. These activities neglect existing, uncontroversial technologies that, in a collaboration between responsible scientists and their publics, could be deployed to address global problems.

We investigate the hardness of establishing as many stable marriages (that is, marriages that last forever) in a population whose memory is placed in some arbitrary state with respect to the considered problem, and where traitors try to jeopardize the whole process by behaving in a harmful manner. On the negative side, we demonstrate that no solution that is completely insensitive to traitors can exist, and we propose a protocol for the problem that is optimal with respect to the traitor containment radius.

In basketball there is the problem of hitting a basket at a determined distance and a determined height. The quantities that can be changed during the inclined throw are the initial velocity and the angle of throw. At first we neglect the air resistance. Then we treat the same problem in a medium (liquid, gas) with constant density. We obtain two differential equations. Then we view special cases of the retarding force.

We investigate the problem of using several storage nodes to store a data object, subject to an aggregate storage budget or redundancy constraint. It is challenging to find the optimal allocation that maximizes the probability of successful recovery by the data collector because of the large space of possible symmetric and nonsymmetric allocations, and the nonconvexity of the problem. For the special case of probability-l recovery, we show that the optimal allocatio...

In the United States, more money is spent on treatment for children's mental health problems than for any other childhood medical condition, yet little is known about usual care treatment for children. Objectives of this study were to characterize usual care outpatient psychotherapy for children with disruptive behavior problems and to identify consistencies and inconsistencies between usual care and common elements of evidence-based practices in order to inform efforts to implement evidence-based practices in usual care. Participants included 96 psychotherapists and 191 children aged four to 13 who were presenting for treatment for disruptive behavior to one of six usual care clinics. An adapted version of the Therapy Process Observational Coding System for Child Psychotherapy-Strategies scale (TPOCS-S) was used to assess psychotherapy processes in 1,215 randomly selected (out of 3,241 collected) videotaped treatment sessions; treatment sessions were recorded for up to 16 months. Most children received a large amount of treatment (mean number of sessions=22, plus children received other auxiliary services), and there was great variability in the amount and type of care received. Therapists employed a wide array of treatment strategies directed toward children and parents within and across sessions, but on average all strategies were delivered at a low intensity. Several strategies that were conceptually consistent with evidence-based practices were observed frequently (for example, affect education and using positive reinforcement); however, others were observed rarely (for example, assigning or reviewing homework and role-playing). Usual care treatment for these youths reflected great breadth but not depth. The results highlight specific discrepancies between evidence-based care and usual care, thus identifying potentially potent targets for improving the effectiveness of usual care.

The Steiner problem asks for a shortest network which spans a given set of points. Minimum spanning networks have been well-studied when all connections are required to be between the given points. The novelty of the Steiner tree problem is that new auxiliary points can be introduced between the original points so that a spanning network of all the points will be shorter than otherwise possible. These new points are called Steiner points - locating them has proved problematic and research has diverged along many different avenues. This volume is devoted to the assimilation of the rich field of intriguing analyses and the consolidation of the fragments. A section has been given to each of the three major areas of interest which have emerged. The first concerns the Euclidean Steiner Problem, historically the original Steiner tree problem proposed by Jarník and Kössler in 1934. The second deals with the Steiner Problem in Networks, which was propounded independently by Hakimi and Levin and has enjoyed the most...

The authors study a general class of bicriteria network design problems. A generic problem in this class is as follows: Given an undirected graph and two minimization objectives (under different cost functions), with a budget specified on the first, find a subgraph from a given subgraph class that minimizes the second objective subject to the budget on the first. They consider three different criteria -- the total edge cost, the diameter and the maximum degree of the network. Here, they present the first polynomial-time approximation algorithms for a large class of bicriteria network design problems for the above mentioned criteria. The following general types of results are presented. First, they develop a framework for bicriteria problems and their approximations. Second, when the two criteria are the same they present a black box parametric search technique. This black box takes in as input an (approximation) algorithm for the criterion situation and generates an approximation algorithm for the bicriteria case with only a constant factor loss in the performance guarantee. Third, when the two criteria are the diameter and the total edge costs they use a cluster based approach to devise approximation algorithms. The solutions violate both the criteria by a logarithmic factor. Finally, for the class of treewidth-bounded graphs, they provide pseudopolynomial-time algorithms for a number of bicriteria problems using dynamic programming. The authors show how these pseudopolynomial-time algorithms can be converted to fully polynomial-time approximation schemes using a scaling technique.
Colored Traveling Salesman Problem.
Li, Jun; Zhou, MengChu; Sun, Qirui; Dai, Xianzhong; Yu, Xiaolong
2015-11-01
The multiple traveling salesman problem (MTSP) is an important combinatorial optimization problem. It has been widely and successfully applied to the practical cases in which multiple traveling individuals (salesmen) share the common workspace (city set). However, it cannot represent some application problems where multiple traveling individuals not only have their own exclusive tasks but also share a group of tasks with each other. This work proposes a new MTSP called colored traveling salesman problem (CTSP) for handling such cases. Two types of city groups are defined, i.e., each group of exclusive cities of a single color for a salesman to visit and a group of shared cities of multiple colors allowing all salesmen to visit. Evidences show that CTSP is NP-hard and a multidepot MTSP and multiple single traveling salesman problems are its special cases. We present a genetic algorithm (GA) with dual-chromosome coding for CTSP and analyze the corresponding solution space. Then, GA is improved by incorporating greedy, hill-climbing (HC), and simulated annealing (SA) operations to achieve better performance. By experiments, the limitation of the exact solution method is revealed and the performance of the presented GAs is compared. The results suggest that SAGA can achieve the best quality of solutions and HCGA should be the choice making good tradeoff between the solution quality and computing time.

Although research in curve shortening flow has been very active for nearly 20 years, the results of those efforts have remained scattered throughout the literature. For the first time, The Curve Shortening Problem collects and illuminates those results in a comprehensive, rigorous, and self-contained account of the fundamental results.The authors present a complete treatment of the Gage-Hamilton theorem, a clear, detailed exposition of Grayson''s convexity theorem, a systematic discussion of invariant solutions, applications to the existence of simple closed geodesics on a surface, and a new, almost convexity theorem for the generalized curve shortening problem.Many questions regarding curve shortening remain outstanding. With its careful exposition and complete guide to the literature, The Curve Shortening Problem provides not only an outstanding starting point for graduate students and new investigations, but a superb reference that presents intriguing new results for those already active in the field.
[Halitosis. A common problem].
Laine, M L; Slot, D E; Danser, M M
2011-12-01
Halitosis is a frequently occurring problem, the cause of which is generally to be found in the mouth. The challenge for oral health care providers is to diagnose it correctly and treat it effectively. Differential diagnosis is of great importance in making a distinction between halitosis which originates in the mouth and which does not originate in the mouth. Oral halitosis can be treated effectively by good oral health care. Plaque accumulation on the tongue is the most common cause of oral halitosis. Tongue cleansing, possibly in combination with a specific mouth wash, is consequently recommended as an element of oral hygiene care. Other oral health problems, such as periodontal disease, caries and ill-fitting removable dentures should be treated adequately to eliminate these problems as potential causes of halitosis.

Revisiting the Lambert's Problem
Izzo, Dario
2014-01-01
The orbital boundary value problem, also known as Lambert Problem, is revisited. Building upon Lancaster and Blanchard approach, new relations are revealed and a new variable representing all problem classes, under L-similarity, is used to express the time of flight equation. In the new variable, the time of flight curves have two oblique asymptotes and they mostly appear to be conveniently approximated by piecewise continuous lines. We use and invert such a simple approximation to provide an efficient initial guess to an Householder iterative method that is then able to converge, for the single revoltuion case, in only two iterations. The resulting algorithm is compared to Gooding's procedure revealing to be numerically as accurate, while having a smaller computational complexity.

The pricing of electricity trasmission requires determining how much use each generator is making of a transmission line and what is each generator's contribution to the system losses. Such problems cannot be solved by only using Kirchoff's laws. This paper proposes two current decomposition axioms based on which the theories and models are established for the current trace problem. To create an efficient algorithm the graph theory is employed. It is proved that there is no directed circuit in a directed current distribution graph. According to this theorem a very simple and efficient algorithm based on recursive elimination process is suggested. A simple example is used to explain the algorithm.

Problems over Information Systems

The problems of estimation of the minimum average time complexity of decision trees and design of efficient algorithms are complex in general case. The upper bounds described in Chap. 2.4.3 can not be applied directly due to large computational complexity of the parameter M(z). Under reasonable assumptions about the relation of P and NP, there are no polynomial time algorithms with good approximation ratio [12, 32]. One of the possible solutions is to consider particular classes of problems and improve the existing results using characteristics of the considered classes. © Springer-Verlag Berlin Heidelberg 2011.

Given a linear system, we consider the problem of finding a small set of variables to affect with an input so that the resulting system is controllable. We show that this problem is NP-hard; indeed, we show that even approximating the minimum number of variables that need to be affected within a multiplicative factor of $c \\log n$ is NP-hard for some positive $c$. On the positive side, we show it is possible to find sets of variables matching this inapproximability barrier in polynomial time....

Managing soil remediation problems.
Okx, J P; Hordijk, L; Stein, A

Soil remediation has only a short history but the problem addressed is a significant one. Cost estimates for the clean-up of contaminated sites in the European Union and the United States are in the order of magnitude of 1,400 billion ECU. Such an enormous operation deserves the best management it can get. Reliable cost estimations per contaminated site are an important prerequisite. This paper addresses the problems related to site-wise estimations.When solving soil remediation problems, we have to deal with a large number of scientific disciplines. Too often solutions are presented from the viewpoint of only one discipline. In order to benefit from the combined disciplinary knowledge and experience, we think that it is necessary to describe the interrelations between these disciplines. This can be realized by developing an adequate model of the desired process which enables to consider and evaluate the essential factors as interdependent components of the total system.The resulting model provides a binding paradigm to the contributing disciplines which will result in improved efficiency and effectivity of the decision and the cost estimation process. In the near future, we will release the "Biosparging and Bioventing Expert Support System", an expert support system for problem owners, consultants and authorities dealing with the design and operation of a biosparging and/or a bioventing system.

Quadratic Assignment Problem (QAP), like Vehicle Routing Problem, is one of those optimization problems that interests many researchers in the last decades. The Quay Management Problem is a specific problem which could be presented as a QAP which involves a double assignment of customers and products toward loading positions using lifting trucks. This study focuses on the routing problem while delivering the customers' demands. In this problem, lifting trucks will route around the storage sections to collect the products then deliver to the customers who are assigned to specific loading positions. The objective of minimizing the residence time for each customer is sought. This paper presents the problem and the proposed model.

Heuristics for Multidimensional Packing Problems
Egeblad, Jens
In this thesis we consider solution methods for packing problems. Packing problems occur in many different situations both directly in the industry and as sub-problems of other problems. High-quality solutions for problems in the industrial sector may be able to reduce transportation and production...... costs significantly. For packing problems in general are given a set of items and one of more containers. The items must be placed within the container such that some objective is optimized and the items do not overlap. Items and container may be rectangular or irregular (e.g. polygons and polyhedra...... methods. Two important problem variants are the knapsack packing problem and the strip-packing problem. In the knapsack packing problem, each item is given a profit value, and the problem asks for the subset with maximal profit that can be placed within one container. The strip-packing problem asks...

Scattering problems in elastodynamics
Diatta, Andre; Kadic, Muamer; Wegener, Martin; Guenneau, Sebastien
2016-09-01
In electromagnetism, acoustics, and quantum mechanics, scattering problems can routinely be solved numerically by virtue of perfectly matched layers (PMLs) at simulation domain boundaries. Unfortunately, the same has not been possible for general elastodynamic wave problems in continuum mechanics. In this Rapid Communication, we introduce a corresponding scattered-field formulation for the Navier equation. We derive PMLs based on complex-valued coordinate transformations leading to Cosserat elasticity-tensor distributions not obeying the minor symmetries. These layers are shown to work in two dimensions, for all polarizations, and all directions. By adaptative choice of the decay length, the deep subwavelength PMLs can be used all the way to the quasistatic regime. As demanding examples, we study the effectiveness of cylindrical elastodynamic cloaks of the Cosserat type and approximations thereof.

The Boolean Isomorphism problem
Agrawal, M. [Indian Institute of Technology, Kanpur (India); Thierauf, T. [Universitaet Ulm (Germany)
1996-12-31
We investigate the computational complexity of the Boolean Isomorphism problem (BI): on input of two Boolean formulas F and G decide whether there exists a permutation of the variables of G such that F and G become equivalent. Our main result is a one-round interactive proof for BI, where the verifier has access to an NP oracle. To obtain this, we use a recent result from learning theory by Bshouty et.al. that Boolean formulas can be learned probabilistically with equivalence queries and access to an NP oracle. As a consequence, BI cannot be {sigma}{sup p}{sub 2} complete unless the Polynomial Hierarchy collapses. This solves an open problem posed in [BRS95]. Further properties of BI are shown: BI has And- and Or-functions, the counting version, No. BI, can be computed in polynomial time relative to BI, and BI is self-reducible.

The pricing of electricity trasmission requires determining how much use each generator is making of a transmission line and what is each generator’s contribution to the system losses. Such problems cannot be solved by only using Kirchoff’s laws. This paper proposes two current decomposition axioms based on which the theories and models are established for the current trace problem. To create an efficient algorithm the graph theory is employed. It is proved that there is no directed circuit in a directed current distribution graph. According to this theorem a very simple and efficient algorithm based on recursive elimination process is suggested. A simple example is used to explain the algorithm .
Medical problems in pregnancy.
Narayan, Bhaskar; Nelson-Piercy, Catherine
2016-12-01
The prevalence of medical problems in pregnancy is increasing because of a complex interplay between demographic and lifestyle factors, and developments in modern medicine. Maternal mortality and morbidity resulting from treatable medical conditions, such as venous thromboembolism, epilepsy and autoimmune disease, have not decreased in recent years. This is despite a marked decrease in overall maternal mortality. It is vital that all physicians acquire a basic knowledge and understanding of medical problems in pregnancy. This includes prepregnancy measures such as counselling and optimisation of medical therapy, as well as multidisciplinary management throughout pregnancy and the postpartum period. Prompt recognition and treatment of acute and chronic illness is of clear benefit, and most drugs and many radiological investigations may be used in pregnancy.

Full Text Available This paper deals with various reasons for treating the problematisation of textbook discourse as an important aspect of its educational design. These reasons are derived from: the nature of learning process, the nature of scientific knowledge and both motivational and cognitive saint achieved through a problematisation of learning material. Implications drawn from these considerations, along with textbook genre possibilities and constrains, lead us to define some basic strategies of textbook discourse problematisation. They refer to: way of presenting knowledge (problem structuring of text, presenting the history of knowledge and different perspectives; use of specific questions and tasks; metacognitive support of the learning process and specific type of textbook language (dialogical problem focused, language of thinking.

This paper proposes the Potluck Problem as a model for the behavior of independent producers and consumers under standard economic assumptions. We model this by using resource allocation in a multi-agent system in which there is no explicit communication among the agents. The model proposed has many applications in modeling systems like electrical power grids with many consumers and producers, service-on-demand in grid computing and peer-to-peer computing environments, maintaining a good ratio between demand and inventory in supply chain management, etc. It is observed that a rational learning approach is unable to achieve equilibrium or near-equilibrium in the Potluck Problem. Instead, a weighted majority learning algorithm is applied, which does much better in maintaining parity of supply and demand in varying-demand situations.

The corrosion problem, it turned out, stemmed from the process called electrolysis. When two different metals are in contact, an electrical potential is set up between them; when the metals are surrounded by an electrolyte, or a conducting medium, the resulting reaction causes corrosion, often very rapid corrosion. In this case the different metals were the copper grounding system and the ferry's aluminum hull; the dockside salt water in which the hull was resting served as the electrolyte. After identifying the source of the trouble, the Ames engineer provided a solution: a new wire-and-rod grounding system made of aluminum like the ferry's hull so there would no longer be dissimilar metals in contact. Ames research on the matter disclosed that the problem was not unique to the Golden Gate ferries. It is being experienced by many pleasure boat operators who are probably as puzzled about it as was the Golden Gate Transit Authority.
