This study describes the trends in students' explanations of biological change in organisms. A total of 96 student volunteers (8 students from each of 2nd, 5th, 8th, and 12th grades from 3 localities) were interviewed individually and each student was presented a series of graphics depicting natural phenomena. Students' explanations to questions of how something occurred were assigned to one of three categories (responses addressing how something occurred, why something occurred, and 'I don't know'). While the number of responses in each category was roughly equivalent in prominence across grade levels, the majority of students were unable to offer a causal explanation of how a phenomena occurred. An unexpected phenomenon was the students' predilection to redirect the interview question so they could answer them. If asked a how question, as they were in every interview instance, 32% the students answered with a 'why' response. The way biology is taught, the structure of biology or/and how we learn it could shed some light into this phenomenon and has implications for science educators.  相似文献

The development of students as lifelong, self-regulating learners is a valued outcome of higher education. To this end, the current project investigated how students in an undergraduate course experienced and responded to a teaching–learning environment where they were expected to take responsibility for their learning. The pedagogic environment of this course was grounded in strategies and activities associated with assessment for learning (AfL). As such, students were expected to participate in activities that provided them with opportunities to exercise control over their learning. Data gathering comprised individual semi-structured interviews and the collection of artefacts. Findings indicated goals helped students know where they were going; exemplars provided insights into what was expected and what constituted quality work; course activities elicited evidence of learning; dialogic interactions around these generated feedback about understandings and progress; the evaluation of exemplars developed evaluative knowledge, skill and expertise; peer review and feedback provided an authentic context for evaluation and monitoring of works-in-progress. It was concluded that, while each of the AfL strategies contributed to student self-regulation, the full impact of AfL as a catalyst for self-regulated learning was realised in the cumulative and recursive effect these strategies had on students’ thinking, actions and feelings.  相似文献

Peer mentoring programs are an important component in the strategy to enhance the first year undergraduate experience. The operation of these programs needs to be informed by evidence as to their effectiveness. In this article we report on a six-year study of the development of a peer mentoring program in which feedback is used to improve program implementation. Evidence from surveys of participants in the program shows that this process has significantly enhanced their experiences and that the effects of these benefits have increased throughout the life of the program. Moreover, participation in the program enhanced the leadership, communication, and organizational skills of the peer mentors.  相似文献

A group randomized controlled trial tested the efficacy of the Friendly Schools program to reduce student bullying behaviour. This socio‐ecological intervention targeted the whole school, classroom, family, and individual students to reduce bullying behaviour. Self‐report data were collected in 29 schools over three years from a cohort of 1968 eight to nine‐year‐olds. Surveys measured frequency of being bullied, bullying others, telling if bullied and observing bullying. Results indicate that intervention students were significantly less likely to observe bullying at 12, 24 and 36 months and be bullied after 12 and 36 months, and significantly more likely to tell if bullied after 12 months than comparison students. No differences were found for self‐reported perpetration of bullying. The findings suggest whole‐of‐school programs that engage students in their different social contexts appear to reduce their experiences of being bullied and increase their likelihood of telling someone if they are bullied.  相似文献

The aims of this study are threefold. First, we investigate the influence of the parent-initiated motivational climate upon elite junior athletes' perfectionistic cognitions. Second, we examine whether the coach-created motivational climate predicts additional variance in elite junior athletes' perfectionistic cognitions beyond the effects associated with the parent-initiated motivational climate. Third, we test the moderating role of athletes' gender and age in the relationship between the parent-initiated and coach-created motivational climates and athletes' perfectionistic cognitions. A total of 190 elite junior athletes (mean age 15.2 years, s?=?1.5, range 10-18) completed the Parent-Initiated Motivational Climate Questionnaire-2 (White & Duda, 1993), the Perceived Motivational Climate in Sport Questionnaire-2 (Newton, Duda, & Yin, 2000), and the Perfectionistic Cognitions Inventory (Flett, Hewitt, Blankstein, & Gray, 1998). Regression analyses revealed that mother- and father-initiated worry-conducive climates, the father-initiated success-without-effort climate, and the coach-created performance motivational climate predicted male athletes' perfectionistic cognitions. Female athletes' perfectionistic cognitions were predicted by the mother-initiated worry-conducive climate, father-initiated learning-enjoyment climate, and both dimensions of the coach-created climate. Finally, athletes' gender emerged as a significant moderator of the mother-initiated worry-conducive climate and athletes' perfectionistic cognitions relationship. Findings confirm that the parent-initiated motivational climate is a significant predictor of athletes' perfectionism-related thoughts, and provide initial support for the influence of the coach-created motivation climate over children's perfectionistic cognitions.  相似文献
