The domain of environmental protection is comprised from many sub-domains as recycling, conserving water, or reducing the consumption of energy. The attitude–behavior gap is partly explained by the gap between the specificity levels of the particular measured behavior and of its antecedent(s). The present study aimed at assessing the effects of general vs. domain-specific behavior’s proximal antecedents included in the theory of planned behavior (TPB) model (intentions, attitudes towards the behavior, subjective norms, and perceived behavioral control) on performance of specific environmental behaviors (EBs) in five environmental sub-domains. We found that in all of the environmental domains examined, a specifically worded TPB model predicted specific behaviors better than a generally worded TPB model did. However, the magnitude of the improvement varied among behavioral domains and the improvement did not arise from the same TPB elements in every domain. The implications for environmental education and for EB research are discussed. 相似文献

This research examines two images of teachers as seen by students of education: the ideal teacher and their own self‐image as teachers. The research compares the students’ perceptions of these two images using two sub‐groups of students of education: students at an academic teachers’ college who will be referred to as student teachers and beginning teachers, who, while teaching, are completing their academic degrees at teachers’ colleges or regional academic colleges. Data were collected from 89 students at the two colleges by means of a questionnaire that included open‐ended questions which were analyzed qualitatively. The findings of the research indicate that there are two major categories that comprise perceptions of the ideal teacher: first, personal qualities; and second, knowledge of the subject taught as well as didactic knowledge. Both groups of students similarly attributed great importance to the personal qualities of the ideal teacher, but there is a difference in their perception of the importance of knowledge: the beginning teachers attributed great importance to knowledge and perceived it as a quality similar in importance to personal characteristics, while the student teachers, who had not begun their teaching careers, attributed less importance to knowledge as a characteristic of the ideal teacher. A quality which was less prominent when profiling the ideal teacher is general education and wide perspectives. The teacher as a socializing agent, a person who promotes social goals, was not mentioned at all. Students maintained that, during their studies, they had improved their qualities as ‘empathetic and attentive’ teachers, ‘knowledgeable in teaching methods’, and in ‘leadership’. But they had hardly improved their knowledge of the subject they taught or their level of general knowledge. The discussion of knowledge and the desirable personal qualities of a teacher is relevant to the current debate regarding the relative merits of disciplinary education in contrast to pedagogical education in preparation for teaching as a profession. The clear preference for disciplinary education by policy makers in Israel and elsewhere in the field of teacher education is contradictory to the emphasis placed on the personal development of future teachers and their pedagogical education by the students of education who participated in this research. 相似文献

We present a new method for analyzing a student's learning over time for a specific skill: analysis of the graph of the student's moment-by-moment learning over time. Moment-by-moment learning is calculated using a data-mined model that assesses the probability that a student learned a skill or concept at a specific time during learning (Baker, Goldstein, & Heffernan, 2010, 2011). Two coders labeled data from students who used an intelligent tutoring system for college genetics. They coded in terms of 7 forms that the moment-by-moment learning curve can take. These labels are correlated to test data on the robustness of students’ learning. We find that different visual forms are correlated with very different learning outcomes. This work suggests that analysis of moment-by-moment learning curves may be able to shed light on the implications of students’ different patterns of learning over time. 相似文献

Schemes are said to underly cognitive processes, including problem solving in Mathematics. An attempt to test the impact of schemes in solving 2-step word-problems was made in an instructional study where two computerized environments were compared. In the S.P.A. (Schemes for Problem Analysis) software, the user works with schemes in order to analyze and solve the problems. When using S.P.A., the solver has to fill in the data in a scheme which is presented graphically. From the scheme the operation is derived in a deterministic manner, and the user (solver) can then calculate the solution. A feedback mechanism follows. In the A.P. (Algebraic Proposer) software the user fills in a table with the data given in the word-problem and then has to find out which operation to use in order to find the solution. The effectiveness of S.P.A. vs. A.P. was empirically examined in an instructional experiment which studied two sixth grade classes during a four month period. The results of the experiment concluded that, in solving easy word problems, both of the two software systems were equally helpful. In harder word-problems, however, those who learned with the S.P.A. experienced more success than those who had learned with A.P. It was also found that S.P.A. was more instrumental in helping low achieving students cope with hard word-problems. 相似文献

The aim of this study was to test the notion that integrating movement into the learning environment contributes to the academic achievements of kindergarten students. One hundred and sixty 4–6 year-old kindergarten students participated in the study for 145 days, which included pre- and post-intervention tests in language, mathematics, and non-verbal intelligence. The three interventions consisted of (a) a mindful movement—integrating movement in academic learning, (b) a movement for its own sake—allowing children free movement without providing academic instruction, and (c) a control condition—children engaging in their regular academic environment activities. The findings revealed that the mindful movement intervention resuted in the highest improvement in the academic achievement tests. Children engaging in movement for its own sake did not differ from the control condition. The findings support the notion that mindful movement enhances kindergarten children’s academic achievements. Possible explanations for this outcome are discussed. 相似文献

OBJECTIVE: This study was designed to determine whether it is possible to prevent those sexually abused boys who are at risk of abusing other children from doing so, and to assess whether factors associated with an experience of sexual abuse in young people who are offending can be dealt with as a key aspect of therapeutic work alongside treatment of offending behavior. METHOD: The author examined cross-sectional and longitudinal research which demonstrates the impact on sexually abused children of living in a climate of violence, suffering physical abuse, exposure to abuse of maternal figures, and suffering disruption and poor quality of care and supervision. These factors are confirmed in prospective research. RESULTS: The application of these findings to therapeutic programs for boys who are sexually abused is described, including the assessment of care needs as well as the specific therapeutic work with the young person, and work to modify the family context. The specific treatment of victimization experiences in young people who have committed sexual offenses is also examined, with recommendations for modification of treatment approaches suggested. CONCLUSION: It is vital in therapeutic work with boy victims of sexual abuse that the issue of their abusive potential be considered, even if a relatively small proportion of such boys will go on to abuse others. Given that boys who do sexually abuse are likely to have grown up in a climate of violence and poor care, methods of dealing with such victimization experiences need to be developed alongside offending focused treatments. 相似文献

Teacher-student relationship is vital for students’ academic, emotional and social development, as well as for teachers’ professional and personal development. This quantitative study examines teacher-student communication and relationship on Facebook among secondary school teachers (N = 180). We examined teachers’ attitudes towards: a) a policy that bans teacher-student Facebook connections; b) using Facebook for learning. Overall, teachers were interested in broadening communication channels with students, in order to empower learning and interpersonal relationship. However, teachers also maintain traditional teacher-student differentiation; they approve using Facebook for learning and disagree with a banning policy, but also prefer using a professional profile for interacting with their students. Data regarding teachers’ perceptions of relationship with their students and SNS-mediated communication present issues regarding means of communication, attitudes towards the policy of banning SNS, standpoints on using Facebook for learning, and preferred profile for communicating with students. We discuss these issues in light of academic, pedagogical, and inter-personal implications. 相似文献

We investigate temporal factors in assessing the authoritativeness of web pages. We present three different metrics related
to time: age, event, and trend. These metrics measure recentness, special event occurrence, and trend in revisions, respectively.
An experimental dataset is created by crawling selected web pages for a period of several months. This data is used to compare
page rankings by human users with rankings computed by the standard PageRank algorithm (which does not include temporal factors)
and three algorithms that incorporate temporal factors, including the Time-Weighted PageRank (TWPR) algorithm introduced here. Analysis of the rankings shows that all three temporal-aware algorithms produce rankings more
like those of human users than does the PageRank algorithm. Of these, the TWPR algorithm produces rankings most similar to human users’, indicating that all three temporal factors are relevant in page
ranking. In addition, analysis of parameter values used to weight the three temporal factors reveals that age factor has the
most impact on page rankings, while trend and event factors have the second and the least impact. Proper weighting of the
three factors in TWPR algorithm provides the best ranking results. 相似文献
