The current study investigates the influence of manipulatives used in combination with traditional approaches to mathematics education and how varying amounts of time spent on manipulative use influence student achievement across different learning styles. Three learning environments were created that incorporated varying proportions of traditional teaching approaches and manipulative methods. In one of the learning environments, the teacher used strictly lecture- and exercise-based teaching activities, which are more conducive to abstract learning. Abstract learners showed higher academic performance compared with concrete learners in the environment where only traditional methods were used. For the other two environments, which utilised varying combinations of manipulative tools and traditional methods, the differences in the mathematics achievement levels among students of varying learning styles were not statistically significant. The study also showed that concrete learners demonstrated higher performance in mathematics when manipulatives were used than did their counterparts in the environment where only abstract activities were used; however, in the third learning environment, increasing the amount of manipulative use did not provide an extra benefit to concrete learners. 相似文献

The study sought to determine if teachers who are taught specific communication skills designed to challenge students’ cognitive and metacognitive thinking during cooperative learning use more challenging and scaffolding behaviours to mediate students’ learning than teachers who implement cooperative learning or small-group work who have not been taught these skills. The study involved 51 teachers in three conditions (cooperative + communication conditions; cooperative condition, group-work condition) and two groups of students from each of the above teachers’ classes. The results show that the teachers in the cooperative + communication condition used significantly more challenging and scaffolding behaviours than teachers in the group-work condition but not more than the teachers in the cooperative condition. The study also showed that the children in the cooperative + communication condition provided significantly more elaborative and help-giving behaviours to group members than peers in the other two conditions and they obtained higher scores on the follow-up reasoning and problem-solving activities than their peers in the group-work condition. 相似文献

The effectiveness and efficiency of individual versus collaborative learning was investigated as a function of instructional format among 140 high school students in the domain of biology. The instructional format either emphasized worked examples, which needed to be studied or the equivalent problems, which needed to be solved. Because problem solving imposes a higher cognitive load for novices than does studying worked examples it was hypothesized that learning by solving problems would lead to better learning outcomes (effectiveness) and be more efficient for collaborative learners, whereas learning by studying worked examples would lead to better learning outcomes and be more efficient for individual learners. The results supported these crossover interaction hypothesis. Consequences of the findings for the design of individual and collaborative learning environments are discussed. 相似文献

A regression design was used to test the unique and interactive effects of self-efficacy beliefs and metacognitive prompting on solving mental multiplication problems while controlling for mathematical background knowledge and problem complexity. Problem-solving accuracy, response time, and efficiency (i.e. the ratio of problems solved correctly to time) were measured. Students completed a mathematical background inventory and then assessed their self-efficacy for mental multiplication accuracy. Before solving a series of multiplication problems, participants were randomly assigned to either a prompting or control group. We tested the motivational efficiency hypothesis, which predicted that motivational beliefs, such as self-efficacy and attributions to metacognitive strategy use are related to more efficient problem solving. Findings suggested that self-efficacy and metacognitive prompting increased problem-solving performance and efficiency separately through activation of reflection and strategy knowledge. Educational implications and future research are suggested. 相似文献

We investigated the influence of self-efficacy beliefs and working memory capacity on mathematical problem-solving performance, response time, and efficiency (i.e., the ratio of problems solved correctly to time). Students completed a letter-recoding task (Experiment 1) or an operation span task (Experiment 2), rated their self-efficacy for solving mental multiplication problems, and then solved similar problems of varying complexity. We tested the motivational efficiency hypothesis, which predicted that motivational beliefs, such as self-efficacy, increase problem-solving efficiency through focused effort and strategy use. Experiments 1 and 2 reported a significant effect for self-efficacy on problem-solving performance and efficiency, but limited effects for time. A self-efficacy by working memory interaction occurred in Experiment 1, suggesting self-efficacy is beneficial as demands on working memory increase. These findings suggested that self-efficacy increased problem-solving efficiency through strategic performance rather than faster solution times, and were consistent with the motivational efficiency hypothesis. 相似文献

This study examined how selected school mathematics textbooks in China, Singapore, and USA at the lower secondary grade level
represent problem-solving procedures. The analysis of problem-solving procedures was carried out in two layers – general strategies,
which adopted Pólya’s four-stage problem-solving model, and specific strategies, which consisted of 17 different problem-solving
heuristics such as ‘acting it out,’ ‘looking for a pattern,’ ‘working backwards,’ etc. Both similarities and differences in
the representation of problem-solving procedures in the textbooks across the three countries were revealed and compared. The
possible reasons for the similarities and especially for the differences were explored. Suggestions about how to improve the
representation of problem-solving in mathematics textbooks were provided at the end of the study.

This article presents findings from a German–Swiss video-based classroom study. The research examines how three basic dimensions of instructional quality impact the development of students' understanding of the Pythagorean Theorem. The study sample comprised 19 German and 19 Swiss mathematics classes. A three-lesson introductory unit on the Pythagorean Theorem was videotaped in all classes. Multilevel analyses revealed both classroom management and cognitive activation to have positive effects on mathematics achievement. The results also provide empirical evidence that cognitive activation and a supportive climate moderate the relationship between mathematics-related interest and mathematics achievement. 相似文献

The concreteness of training materials influences learning and—perhaps more importantly—transfer. Building on prior research finding abstract representations best facilitated transfer to a game task, we conducted a similar study using training figures varying in concreteness but directly assessed transfer to modular arithmetic problems. Training figures: (a) were purely abstract, (b) were abstract but with features relevant to the transfer task, or (c) included additional concrete-relevant features. We hypothesized that concreteness—or number of relevant features—would be positively correlated with learning and transfer—especially among younger and/or lower-ability students. Although there was no overall difference in initial learning, the concrete-relevant and abstract-relevant features independently facilitated near-transfer, where concrete-relevant features supported lower-reasoning students. For far-transfer, eighth-graders benefited from the abstract-relevant features, whereas sixth-graders required additional concrete-relevant features. These findings suggest that concreteness interacts with learner and task characteristics to produce learning and transfer outcomes. 相似文献

This study investigated the influence of informational complexity and working memory capacity on problem-solving efficiency.
We examined two predictions of thesituational efficiency hypothesis, which states that the efficiency of problem solving varies as a function of situational constraints. One prediction is that
informational complexity affects problem-solving efficiency. A second prediction is that working memory capacity affects problem-solving
efficiency. Students completed a working memory task and solved abstract and concrete syllogisms. Participants solved abstract
syllogisms more accurately than concrete syllogisms and spent more time solving abstract syllogisms. Thus participants demonstrated
greater problem-solving efficiency when solving concrete syllogisms. Results indicate that there is a trade-off between problem-solving
accuracy and problem-solving time when information differs with respect to informational complexity, a phenomenon we refer
to as theefficiency paradox. Working memory capacity did not affect accuracy or efficiency. The results support the conclusion that problem-solving efficiency
is situational and a function of the complexity of information. Educational implications and directions for future research
are suggested. 相似文献
