The main aim of this research study was to test out a conceptual model encompassing the theoretical frameworks of achievement goals, study processing strategies, effort, and reflective thinking practice. In particular, it was postulated that the causal influences of achievement goals on academic performance are direct and indirect through study strategies, effort, and reflective thinking. Furthermore, the effects of study strategies on academic performance are hypothesised to be direct and indirect through reflective thinking practice. Participants were 298 (182 females, 116 males) university students. Likert‐response questionnaires were used and data were analysed by means of latent variables approaches. The results provided moderate support for the hypothesised conceptual model. Achievement goals had no direct effects on academic performance, whereas study strategies and reflective thinking directly influenced performance. Mastery goals directly influenced deep processing and effort, whereas performance avoidance and work avoidance influenced surface processing and effort. A one‐way MANOVA indicated, with the exception of understanding, no statistical significance between males and females in the variables. This evidence is theoretically significant as it highlights the mediating mechanism of study strategies and reflective thinking and, more importantly, amalgamates different theoretical frameworks within one study. 相似文献

We recently developed the Framework of Achievement Bests to explain the importance of effective functioning, personal growth, and enrichment of well-being experiences. This framework postulates a concept known as optimal achievement best, which stipulates the idea that individuals may, in general, strive to achieve personal outcomes, reflecting their maximum capabilities. Realistic achievement best, in contrast, indicates personal functioning that may show moderate capability without any aspiration, motivation, and/or effort expenditure. Furthermore, our conceptualization indicates the process of optimization, which involves the optimization of achievement of optimal best from realistic best.In this article, we explore the Framework of Achievement Bests by situating it within the context of student motivation. In our discussion of this theoretical orientation, we explore in detail the impact of instructional designs for effective mathematics learning as an optimizer of optimal achievement best. Our focus of examination of instructional designs is based, to a large extent, on cognitive load paradigm, theorized by Sweller and his colleagues. We contend that, in this case, cognitive load imposition plays a central role in the structure of instructional designs for effective learning, which could in turn influence individuals’ achievements of optimal best. This article, conceptual in nature, explores varying efficiencies of different instructional approaches, taking into consideration the potency of cognitive load imposition. Focusing on mathematical problem solving, we discuss the potentials for instructional approaches to influence individuals’ striving of optimal best from realistic best. 相似文献

We examined the use of balance and inverse methods in equation solving. The main difference between the balance and inverse methods lies in the operational line (e.g. +2 on both sides vs ?2 becomes +2). Differential element interactivity favours the inverse method because the interaction between elements occurs on both sides of the equation for the balance method but only on one side of the equation for the inverse method. In an experimental study, 63 students (mean age = 13) were randomly allocated to either balance or inverse group to undertake a pre-test, study an instruction sheet, complete acquisition equations, sit for a post-test and a concept test. Procedural knowledge was assessed on performance on practice equations and post-test, whereas conceptual knowledge was assessed on performance on the concept test. The inverse group outperformed the balance group on practice equations but not the post-test. Both the balance and inverse groups scored higher on the inverse concept test than the balance concept test. Positive association between performance on procedural knowledge and performance on conceptual knowledge was found for the inverse group but not the balance group. Overall, the evidence obtained indicates a number of educational implications for implementation. 相似文献

Research exploring students’ academic learning has recently amalgamated different motivational theories within one conceptual framework. The inclusion of achievement goals, self‐efficacy, deep processing and critical thinking has been cited in a number of studies. This article discusses two empirical studies that examined these four theoretical orientations from both cross‐sectional (N = 279 participants) and longitudinal (N = 264 participants) perspectives. In particular, achievement goals are hypothesised to exert direct and indirect effects on academic performance via self‐efficacy, study processing strategies and critical thinking. Path analysis was used to test and analyse the hypothesised conceptual models. Results from SPSS 16 and LISREL 8.72 provided good support for the hypothesised structural relationships. Students’ academic performance outcomes, for example, are determined directly by deep processing and work‐avoidance goals. Results from Study 2 indicate mastery goals and self‐efficacy, mastery goals and critical thinking and deep processing and critical thinking operate in a reciprocal manner. In general, the evidence established from both studies contributes theoretically and methodologically. 相似文献

Personal self-efficacy is an important theoretical orientation that helps to explain students’ learning and academic achievements. One area of research inquiry has involved the four major sources of information and their predictive effects on self-efficacy. As an extension for examination, the purpose of our investigation was to explore the interrelations between antecedents (e.g. enactive performance accomplishment), self-efficacy beliefs and academic achievement of elementary school students. Our research conceptualisation, unlike previous cross-sectional studies, entails a time displacement between sources of information (Time 1) and self-efficacy (Time 2 and Time 3) and between self-efficacy and academic achievement in science learning (Time 4). Three hundred and thirty-two (152 girls and 180 boys) third and fourth grade students from three government schools participated in this study. Likert-scale inventories were used to measure informational sources and self-efficacy beliefs. Structural equation modelling yielded evidence that supports, in part, our conceptual model. Only enactive performance accomplishment and vicarious experience exerted positive temporally displaced effects on self-efficacy. Self-efficacy at both Time 2 and Time 3 also contributed to the prediction of academic achievement. 相似文献

One important line of inquiry in educational psychology involves the study of change of individuals' cognitive-motivational processes. The conjunctive use of longitudinal data with latent growth curve modeling procedures has, for example, allowed researchers to identify initial levels and to trace trajectories of theoretical variables such as self-efficacy over time. The study reported in this article proposed a conceptual model that depicted relations between a deep-learning approach, mastery goals and self-efficacy over time. A final sample of 195 second-year university students (100 females, 95 males) took part in this three-wave panel study. We used various inventories to test the initial states and rates of change of the three aforementioned constructs. As an a posteriori analysis, we included prior academic achievement as a possible predictor of change. The results ascertained from our analyses indicate an increase in growth of a deep-learning approach, mastery goals and self-efficacy across the two-year period. Importantly, a posteriori results accentuated the role of prior academic achievement as a predictor of the initial level of personal self-efficacy. 相似文献

Students’ academic performance and various cognitive processes of learning: an integrative framework and empirical analysis 总被引：3，自引：1，他引：2
Huy Phuong Phan 《教育心理学》2010,30(3):297-322
The main aim of this study is to test a conceptualised framework that involved the integration of achievement goals, self‐efficacy and self‐esteem beliefs, and study‐processing strategies. Two hundred and ninety (178 females, 112 males) first‐year university students were administered a number of Likert‐scale inventories in tutorial classes. Data were analysed through structural equation modelling procedures. The results provided support, in part, for the hypothesised relationships; for example, both self‐efficacy and self‐esteem exerted positive effects on deep processing, and academic performance was influenced positively by mastery goals and deep processing. Similarly, surface processing exerted a negative effect on academic performance. One key finding was the positive effect that self‐esteem exerted on self‐efficacy. Finally, a one‐way MANOVA indicated statistically significant differences between men and women in their self‐esteem; women reported higher self‐esteem than men. This study provides support for the amalgamation of key motivational and learning theories and accentuates the importance of achievement goals, self‐efficacy and study‐processing strategies as possible mediators of students’ academic performance. 相似文献
