This study examined the effect of cognitive demand on situational interest and performance using running tasks in physical education. Adolescents (N = 179) participated in a field study involving three different levels of cognitive demand. Running performances and situational interest were measured four times with a testing interval of seven days. Results from multivariate analyses of covariance suggested that cognitive demand had a significant effect on situational interest and running performances. Higher cognitive demand led to higher levels of situational interest. Situational interest was weakly or moderately correlated with running performances (|r| = .17?.40), yet students reported significantly lower performance when the perceived interest was the highest. These findings suggest the importance of designing instructional tasks with moderate cognitive demand to optimally preserve situational interest and performance in physical education. The findings also help further conceptualise the relations among cognitive demand, situational interest and performance.  相似文献

Materials science, which entails the practices of selecting, testing, and characterizing materials, is an important discipline within the study of matter. This paper examines how third grade students’ materials science performance changes over the course of instruction based on an engineering design challenge. We conducted a case study of nine students who participated in engineering design-based science instruction with the goal of constructing a stable, quiet, thermally comfortable model house. The learning outcome of materials science practices was assessed by clinical interviews conducted before and after the instruction, and the learning process was assessed by students’ workbooks completed during the instruction. The interviews included two materials selection tasks for designing a sturdy stepstool and an insulated pet habitat. Results indicate that: (1) students significantly improved on both materials selection tasks, (2) their gains were significantly positively associated with the degree of completion of their workbooks, and (3) students who were highly engaged with the workbook’s reflective record-keeping tasks showed the greatest improvement on the interviews. These findings suggest the important role workbooks can play in facilitating elementary students’ learning of science through authentic activity such as engineering design.  相似文献

One way of engaging the public in major environmental issues, such as biodiversity loss, is citizen science. Up to now, the potential of implementing citizen science into formal learning environments has remained largely unconsidered. We engaged 276 German 10th graders in a collaborative citizen science project on DNA barcoding as part of a biodiversity education module. Our research focused on monitoring the relation between fascination for biology and students’ cognitive performance. Following a pre-post-retention design, we measured content knowledge and fascination one week before, one week after, and six weeks after participation in the project. Our findings indicate fascination to be a variable positively related to science learning: in relation to their pre-knowledge scores, all students showed short-term knowledge gain. In the long-term, however, students with high fascination scores retained more knowledge than students with intermediate or low fascination scores.  相似文献

The study explores if established support devices for paper–pencil problem solving, namely worked examples and incremental scaffolds, are applicable to laboratory tasks. N?=?173 grade eight students solved in dyads a physics laboratory task in one of three conditions. In condition A (unguided problem solving), students were asked to determine the mass of an unknown object by applying Hooke’s law. In condition B (laboratory guide), students received a guide which instructed and explained each solution step. In condition C (incremental scaffolds), the solution steps were presented incrementally on learner demand and were preceded by strategic prompts. Dependent variables were learning outcomes (solution, retention, knowledge) and motivational learning experiences (basic needs, situational interest, deeper level processing). The laboratory guide (B) led to better learning outcomes (d?=?0.42) but lower motivation (d?>?0.38) compared to unguided problem solving (A). Incremental scaffolds (C) led to higher motivation (d?>?0.44) but similar learning outcomes compared to a laboratory guide.  相似文献

In recent years, the mathematics achievement of Peruvian students has been evaluated in three national and two international studies. The results in all cases suggest very poor learning. A similar situation is found in many developing countries. In this study, we analyzed the opportunities to learn (OTL) mathematics of sixth grade students from 22 public schools in Lima, Peru. OTL were defined in this study as curriculum coverage, cognitive demand of the tasks posed to the students, percent of mathematical exercises that were correct and quality of feedback. These variables were coded in the workbooks and notebooks of the students, which were gathered at the end of the school year (at the same time, the mathematics achievement test was administered). The results show that: (a) regarding OTL, less than half of the exercises available in the workbooks were solved, teachers overemphasize some topics of the national curriculum ({i.e.} related to Number and Number Sense), they pose tasks that are at very low levels of cognitive demand, and it is common to find mistakes in the students' answers to problems that have no feedback (or even worse, the feedback is wrong); (b) students in relatively poorer, multigrade classrooms have less OTL; (c) OTL, as defined earlier, is positively associated with achievement.A preliminary version of this paper received the Research Medal in the category Knowledge, Education andTechnology at the Annual Meeting of the Global Development Network (GDN) in Cairo, in January 2003.  相似文献

Drawing strategies are widely used as a powerful tool for promoting students’ learning and problem solving. In this article, we report the results of an inferential mediation analysis that was applied to investigate the roles that strategic knowledge about drawing and the accuracy of different types of drawings play in mathematical modelling performance. Sixty-one students were asked to create a drawing of the situation described in a task (situational drawing) and a drawing of the mathematical model described in the task (mathematical drawing) before solving modelling problems. A path analysis showed that strategic knowledge about drawing was positively related to students’ modelling performance. This relation was mediated by the type and accuracy of the drawings that were generated. The accuracy of situational drawing was related only indirectly to performance. The accuracy of mathematical drawings, however, was strongly related to students’ performance. We complemented the quantitative approach with a qualitative in-depth analysis of students’ drawings in order to explain the relations found in our study. Implications for teaching practices and future research are discussed.  相似文献

Design activities, when embedded in an inquiry cycle and appropriately scaffolded and supplemented with reflection, can promote the development of the habits of mind (scientific abilities) that are an important part of scientific practice. Through the Investigative Science Learning Environment (ISLE), students construct physics knowledge by engaging in inquiry cycles that replicate the approach used by physicists to construct knowledge. A significant portion of student learning occurs in ISLE instructional labs where students design their own experiments. The labs provide an environment for cognitive apprenticeship enhanced by formative assessment. As a result, students develop interpretive knowing that helps them approach new problems as scientists. This article describes a classroom study in which the students in the ISLE design lab performed equally well on traditional exams as ISLE students who did not engage in design activities. However, the design group significantly outperformed the non-design group while working on novel experimental tasks (in physics and biology), demonstrating the application of scientific abilities to an inquiry task in a novel content domain. This research shows that a learning environment that integrates cognitive apprenticeship and formative assessment in a series of conceptual design tasks provides a rich context for helping students build scientific habits of mind.  相似文献

The aim of the present study was to investigate those factors influencing performance in solving story problems in a web-based environment. A situational simulation, “Hiking across Estonia,” was explored by two samples of voluntary groups of students, comprising 65 and 50 groups, respectively. They solved 25 ecological and environmental story problems and filled in a pre-test and post-test that evaluated problem-solving skills. The groups were clustered according to their characteristics and performance into five clusters: “slow learners,”“quick learners,”“successful learners,”“smart learners,” and “ineffective learners.” The clusters were provided with different types of supportive notes and the sequence of problems was rearranged according to the students' initial results in the first four problem-solving tasks. These treatments demonstrated statistically significant improvements in the outcome in solving story problems in small groups. The main factors determining the effectiveness of problem solving were: (i) time spent on learning; (ii) initial skills in problem-solving; (iii) the presence of support in enhancing situation awareness; (iv) graduated problem tasks sequenced on the basis of complexity and difficulty; (v) ratio of genders in a learning group. However, the importance of these factors depended on the cluster and, therefore, it can be concluded that the design of problem-solving instruction has to be adapted according to the clusters' characteristics.  相似文献

In a task choice situation, why do some students spontaneously choose challenging tasks while others do not? In the study, 114 undergraduate students were first asked of their perceived competence and interest in solving number puzzles at both individual and situational levels, and then asked to choose one puzzle from four difficulty levels. They received no performance feedback throughout the session. Regression analyses indicated that the students with higher individual interest levels chose more challenging puzzles, while the students with higher levels of perceived competence and low levels of individual interest did not necessarily choose difficult puzzles. The students who chose more challenging puzzles attributed their choices to interest rather than perceived competence. The study suggests a limitation of relying on students' self-reported confidence in their ability and the importance of conceptualizing individual interest as the reason behind the choice of challenging tasks in a low-pressure task choice environment.  相似文献

Participants in the present study were 87 college students who learned about botany using an agent-based instructional program with three different learning approaches: individual, jigsaw, or cooperative learning. Results showed no differences among learning approaches on retention. Students in jigsaw groups reported higher cognitive load during learning than students who learned individually; scored lower on a problem-solving transfer test than students in individual and cooperative learning groups; and were less likely to produce elaborated explanations and co-construct knowledge with their peers than students in cooperative groups. Students in cooperative groups reported higher situational interest than their counterparts. Implications for cooperative and individual meaning making in agent-based instructional programs are discussed and future research directions are suggested.  相似文献

The extent to which a student experiences situational interest during a learning task is dependent on at least two factors: (1) external stimuli in the learning environment that arouse interest and (2) internal dispositions, such as individual interest. The objective of the present study was to disentangle how both factors influence situational interest during task engagement. Two data sets were collected from primary school science (N = 186) and secondary school history students (N = 71). Path analysis was used to examine the influence of individual interest on seven situational interest measurements and knowledge acquisition. The results suggest that individual interest has only a significant influence on situational interest at the beginning of a task and then its influence fades. In addition, individual interest is not a significant predictor of learning. Only situational interest predicts knowledge acquisition. Implications of these findings for interest research are discussed.  相似文献

Abstract

To help introductory programming students gain an integrated, generative understanding of LISP, we designed, implemented, and evaluated the LISP Knowledge Integration Environment (LISP‐KIE). The LISP‐KIE reflected a conceptual framework which featured (a) scaffolding of students as they control their own learning rather than telling students what they should know and (b) activities engaging students in expert problem‐solving practices rather than exercises emphasizing syntax and small problems. We conducted two in‐depth studies and one comparison study to show that the LISP‐KIE fostered knowledge integration. By knowledge integration, we mean linked, organized, and connected information about such aspects of programming as design, testing, specific problem solutions, and self‐monitoring.  相似文献

The effects of topic knowledge, text coherence, and topic interest on learning from text were examined. One hundred sixty high school students participated in 1 of 4 groups according to their levels of topic knowledge and interest. Participants read 1 of 3 versions of a scientific text: minimally coherent, locally coherent, and locally and globally coherent. Text comprehension was examined by tasks aimed at tapping both textbase and situation-model levels. The contribution of topic interest seemed to increase according to the quantity of learners' topic knowledge. High-knowledge and high-interest students performed significantly better than those in the other 3 groups in all tasks. Text version differentiated students' performance on all measures but 1. The expected Group x Version interactions did not emerge.  相似文献

A methodology for studying change during instruction in content-specific cognitive processes is presented. The methodology borrows both from the cognitive mediational approach in instructional effectiveness research and the instructional approach in cognitive psychology research. It is argued that learning from instruction must be understood in terms of the way in which instruction changes the cognitive processes used to solve tasks. The methodology is illustrated by summarizing a project on instructing middle-school students in semantic processes for solving decimal-fraction problems. The benefits of the methodology, such as tracing the effects of instruction on performance change, are discussed.  相似文献

For self-regulated learning to be effective, students need to be able to accurately assess their own performance on a learning task and use this assessment for the selection of a new learning task. Evidence suggests, however, that students have difficulties with accurate self-assessment and task selection, which may explain the poor learning outcomes often found with self-regulated learning. In experiment 1, the hypothesis was investigated and confirmed that observing a human model engaging in self-assessment, task selection, or both could be effective for secondary education students’ (N = 80) acquisition of self-assessment and task-selection skills. Experiment 2 investigated and confirmed the hypothesis that secondary education students’ (N = 90) acquisition of self-assessment and task-selection skills, either through examples or through practice, would enhance the effectiveness of self-regulated learning. It can be concluded that self-assessment and task-selection skills indeed play an important role in self-regulated learning and that training these skills can significantly increase the amount of knowledge students can gain from self-regulated learning in which they choose their own learning tasks.  相似文献

Increasing Situational Interest in the Classroom   总被引:4,自引:0,他引:4  
This paper explores three ways to increase situational interest in the classroom. Situational interest is defined as temporary interest that arises spontaneously due to environmental factors such as task instructions or an engaging text. We review the history of interest research and summarize recent empirical work. We describe three ways to increase interest based on offering meaningful choices to students, selecting well-organized texts that promote interest, and providing the background knowledge needed to fully understand a topic. We conclude with six specific suggestions for increasing situational interest in the classroom.  相似文献

Instructors are faced with the challenge of engaging students in the learning process. This study examined the effects of participation requirements on students' (N = 258) affective learning, interest, and cognitive learning using the Affective Learning Model and the Instructional Beliefs Model. Affective learning mediated the relationship between student participation requirements and cognitive learning, and student interest mediated the relationships between participation requirements and cognitive learning, supporting the IBM. The results provide insight into course-specific structural tactics that instructors can employ to enhance the educational experience for college students.  相似文献
