The purpose of this research was to develop and test a multicausal model of the individual characteristics associated with academic success in first‐year Australian university students. This model comprised the constructs of: previous academic performance, achievement motivation, self‐regulatory learning strategies, and personality traits, with end‐of‐semester grades the dependent variable of interest. The study involved the distribution of a questionnaire, which assessed motivation, self‐regulatory learning strategies and personality traits, to 1193 students at the start of their first year at university. Students' academic records were accessed at the end of their first year of study to ascertain their first and second semester grades. This study established that previous high academic performance, use of self‐regulatory learning strategies, and being introverted and agreeable, were indicators of academic success in the first semester of university study. Achievement motivation and the personality trait of conscientiousness were indirectly related to first semester grades, through the influence they had on the students' use of self‐regulatory learning strategies. First semester grades were predictive of second semester grades. This research provides valuable information for both educators and students about the factors intrinsic to the individual that are associated with successful performance in the first year at university.  相似文献

Torture of children occurs in many different ways: children may be forcibly adopted by strangers; children may be arrested and imprisoned; they may witness torture of their parents or may be tortured in the presence of their parents; and, similarly several reports of mass executions of children are available.The Danish Medical Group under Amnesty International has investigated 88 Chilean children now living in Denmark, whose parents had been tortured. Approximately 13 of the children were abnormally anxious and approximately 13 had disturbances of sleep in the form of difficulty falling asleep accompanied by broken sleep with nightmares. Approximately 14 of the children developed secondary nocturnal enuresis. Seventeen percent of the children showed behaviour difficulties in the form of aggression while 16% became introverted and depressed and had difficulties in establishing contact with children of the same age-group.  相似文献

A causal model for understanding the complex interplay between student‐reported teacher behaviors, student self‐systems, and student engagement was tested. One hundred seventeen African American students in grades 1 through 12 completed a comprehensive questionnaire regarding teacher context, self, and engagement variables. A series of hierarchical regression analyses were conducted to test the hypothesized mediation models and to construct a path model. Most hypotheses were supported. Student self‐system variables (perceived competency and autonomy) mediated relations between teacher context (structure and autonomy support), and engagement. Contrary to predictions, however, teacher involvement exerted a strong and direct effect on student engagement even when controlling for grade level and self‐system variables. Given existing research showing that African American students are at risk for low teacher involvement and that engagement is critical for academic success, research and intervention strategies are urgently needed to promote teacher involvement with these students. © 2002 Wiley Periodicals, Inc.  相似文献

Although instructional explanations are commonly used to introduce learners to new learning content, previous studies have often shown that their effects on learning outcomes are minimal. This failure might partly be due to mental passivity of the learners while processing introductory explanations and to a lack of opportunity to revise potential misunderstandings after working on introductory explanations. Against this background, we provided learners with two instructional support measures to optimise the introduction of new principles and concepts by providing instructional explanations in the domain of management theory: (a) prompts designed to induce inferences that are focused on the central content of the explanations, and (b) remedial explanations that are adapted to the learners’ knowledge gaps. We tested their effects in a 2 × 2 factorial experimental design with the following factors: (a) prompts designed to induce focused processing (with vs. without), and (b) remedial explanations (adapted vs. random). The participants consisted of 80 psychology students. We found that the prompts fostered both the share of deep-oriented processing and the acquisition of conceptual knowledge. The beneficial effect of prompts on conceptual knowledge was mediated by the number of inferences that learners generated in response to the prompts. In addition, we found that prompts also fostered the instructional efficiency of providing instructional explanations. The provision of adapted remedial explanations, however, fostered neither deep-oriented processing nor the acquisition of conceptual knowledge. We conclude that prompts designed to induce focused processing can foster deep-oriented processing as well as both the effectiveness and efficiency of learning from instructional explanations.  相似文献

Adjunct questions are a common means to foster learning from instructional explanations. As the benefit of adjunct questions is mitigated if learner performance on them is low, it is also common to provide feedback as an add-on if learners fail to correctly respond to them. However, if adjunct questions are highly demanding, feedback might not only beneficially affect learning because it helps learners revise their comprehension difficulties; at the same time, it could also detrimentally affect learning by causing learners to invest less time in responding to subsequent adjunct questions, which lowers learner performance on these questions. This, in turn, could reduce learning outcomes. To address these potential detrimental effects of feedback, we experimentally varied whether N?=?59 students received immediate feedback after they responded to highly demanding adjunct questions. We found that the feedback did indeed have detrimental effects: At least for the learners who perceived the task of responding to the adjunct questions as highly demanding, the feedback decreased both the time the learners invested in responding to the adjunct questions and their performance on them. This detrimental effect on the performance on the adjunct questions, in turn, entailed a detrimental effect on learning outcomes. We conclude that immediate feedback is not necessarily a beneficial add-on to adjunct questions in all situations.  相似文献

Previous research investigating the response of plasma ß‐endorphins (ß‐EP) to resistance exercise has resulted in equivocal findings. To further examine the effects of resistance exercise on ß‐endorphin immunoreactivity, six resistance‐trained athletes participated in a three‐set series of eight repetitions of isotonic exercise. All exercises were performed at 80% maximal effort. Blood was sampled from the group by venepuncture, both prior to and following the exercise bout, and ß‐endorphin concentration was determined by radioimmunoassay. The results indicated that mean ( ± S.E.) plasma levels of ß‐endorphins following exercise (18.04 ± 3.4 pg ß‐EP ml‐1) were not significantly changed from pre‐exercise (control) levels (19.59 ± 2.4 pg ß‐EP ml‐1), although there was considerable inter‐individual variability. Our results support previous research which has reported no significant changes in ß‐endorphin immunoreactivity following resistance exercise, as well as reported findings of considerable variability in the ß‐endorphin response to exercise.  相似文献
