We investigated perceptions about learning strategy use and instructional roles among a sample of high needs adolescents (n = 230) who acted as near-peer instructional facilitators. The sample was drawn from science and mathematics classes in nonselective public secondary schools in New York City. Students participated in an inschool intervention that draws on social constructivism, theory and research on metacognition and learning strategies, role theory, and empirical findings from the peer-to-peer learning literature to promote advanced achievement among students who act as facilitators. Using a pre- and post-test single group design, we surveyed student instructional facilitators before and after program participation and related their perceptions about learning strategy use and perceptions about teaching roles to data about academic achievement. We found no survey gains in student perceptions about learning strategies or instructional roles between pre-survey (fall) and post-survey (spring). We found small but significant effects of individual perceptions about learning strategies and teaching roles on academic gains among instructional facilitators. The study also suggests that an in-school near-peer facilitated learning program can be an effective means to raise achievement in urban high schools. The study provides partial support for theories that hold that metacognition and role perceptions are involved in the academic gains of instructional facilitators, as gains in these dimensions were small compared to achievement gains.  相似文献

Productive failure in mathematical problem solving   总被引：1，自引：0，他引：1  
This paper reports on a quasi-experimental study comparing a “productive failure” instructional design (Kapur in Cognition and Instruction 26(3):379–424, 2008) with a traditional “lecture and practice” instructional design for a 2-week curricular unit on rate and speed. Seventy-five, 7th-grade mathematics students from a mainstream secondary school in Singapore participated in the study. Students experienced either a traditional lecture and practice teaching cycle or a productive failure cycle, where they solved complex problems in small groups without the provision of any support or scaffolds up until a consolidation lecture by their teacher during the last lesson for the unit. Findings suggest that students from the productive failure condition produced a diversity of linked problem representations and methods for solving the problems but were ultimately unsuccessful in their efforts, be it in groups or individually. Expectedly, they reported low confidence in their solutions. Despite seemingly failing in their collective and individual problem-solving efforts, students from the productive failure condition significantly outperformed their counterparts from the lecture and practice condition on both well-structured and higher-order application problems on the post-tests. After the post-test, they also demonstrated significantly better performance in using structured-response scaffolds to solve problems on relative speed—a higher-level concept not even covered during instruction. Findings and implications of productive failure for instructional design and future research are discussed.  相似文献

A crucial skill for researchers in inter- and transdisciplinary environmental projects is the ability to be reflexive about knowledge and knowledge production. Few studies exist on the operationalization of reflexive skills and teaching and learning strategies that help students master these skills. This research aims to contribute in this direction. We distinguished two components of reflexive skills: (i) assessing the relative contributions of scientific disciplines and non-academic knowledge in addressing environmental issues; (ii) assessing the role of norms and values in research. We developed a framework for teaching and learning reflexive skills and evaluated this framework within a quasi-experimental educational setting involving 3 groups of 30 students. Students’ reflexive skills were assessed quantitatively using a pre- and post-test questionnaire. Moreover, students’ reflection papers were analysed to get a better understanding of their perspectives on the teaching and learning framework. We show that it is possible to train students in reflexive skills, but it requires a well-designed learning setting.  相似文献

Experimental skills should be acquired by learners at school and university alike. To promote experimental skills, various approaches exist within a spectrum between implicit and explicit instruction. Regarding these instructional approaches, numerous findings are available which predominantly relate to pupils. It is an open question whether it is better to instruct experimental skills explicitly or implicitly in university courses. And if experimental skills are fostered explicitly, what about the content-related skills? Especially in teaching programmes with both experiment-related and content-related objectives, it is questionable whether content-related objectives are achieved to a lesser degree via explicit instruction of experimental skills. Both questions are addressed in this paper. We present an intervention study involving 144 students. All students carry out the same experiments. The intervention groups differ merely in the degree of explicit instruction. Learning gains in experimental and content-related skills are assessed in a pre-/post-test design. The results show that the type of instruction does not significantly influence the acquisition of experimental and content-related skills in this target group. But by trend, the expected differences in learning gains can be observed. This leads to new research perspectives and implications for teaching which are discussed.  相似文献

This paper concerns the identification of teaching strategies that enhance the development of 4th grade students’ experimental design skills at a public primary school in Argentina. Students’ performance in the design of relevant experiments was evaluated before and after an eight-week intervention compared to a control group, as well as the persistence of this learning after eight months. The study involved a quasi-experimental longitudinal study with pre-test/post-test/delayed post-test measures, complemented with semi-structured interviews with randomly selected students. Our findings showed improvement in the experimental design skills as well as its sustainability among students working with the inquiry-based sequence. After the intervention, students were able to establish valid comparisons, propose pertinent designs and identify variables that should remain constant. Contrarily, students in the control group showed no improvement and continued to solve the posed problems based on prior beliefs. In summary, this paper shows evidence that implementing inquiry-based units involving problems set in cross-domain everyday situations that combine independent student work with teacher guidance significantly improves the development of scientific skills in real classroom contexts.  相似文献

This paper presents the effects of a cognitive acceleration program in mathematics classes on Tongan students’ achievements, motivation and self-regulation. Cognitive Acceleration in Mathematics Education (CAME) is a program developed at King’s College and implemented worldwide with the aim of improving students’ thinking skills, mathematics performance and attitudes. The first author adapted the program materials to Tongan educational context and provided support to participating teachers for 8 months. This study employed a quasi-experimental design with 219 Year 8 students as the experimental group and 119 Year 8 students as the comparison group. There were a significant differences in the mean scores between the pre-test and post-test of the three instruments that were employed in the study, indicating that learning mathematics under the CAME program had a positive effect on levels of students’ self-regulation, motivation and mathematics achievement. Students also reported changes to the ways they learn mathematics.  相似文献

Problem-Based Learning: What and How Do Students Learn?   总被引：22，自引：0，他引：22  
Problem-based approaches to learning have a long history of advocating experience-based education. Psychological research and theory suggests that by having students learn through the experience of solving problems, they can learn both content and thinking strategies. Problem-based learning (PBL) is an instructional method in which students learn through facilitated problem solving. In PBL, student learning centers on a complex problem that does not have a single correct answer. Students work in collaborative groups to identify what they need to learn in order to solve a problem. They engage in self-directed learning (SDL) and then apply their new knowledge to the problem and reflect on what they learned and the effectiveness of the strategies employed. The teacher acts to facilitate the learning process rather than to provide knowledge. The goals of PBL include helping students develop 1) flexible knowledge, 2) effective problem-solving skills, 3) SDL skills, 4) effective collaboration skills, and 5) intrinsic motivation. This article discusses the nature of learning in PBL and examines the empirical evidence supporting it. There is considerable research on the first 3 goals of PBL but little on the last 2. Moreover, minimal research has been conducted outside medical and gifted education. Understanding how these goals are achieved with less skilled learners is an important part of a research agenda for PBL. The evidence suggests that PBL is an instructional approach that offers the potential to help students develop flexible understanding and lifelong learning skills.  相似文献

This study aimed at experimentally investigating the moderating role of instructional conceptions on the effectiveness of powerful learning environments (PLE) designed in line with the four-component instructional design model (4C/ID-model). The study also investigated the influence of learning in a 4C/ID PLE on students’ instructional conceptions. To achieve its goal, a study with a one by one by two pre-test post-test quasi-experimental design was done. Three functionally equivalent classes of students from three similar (secondary technical) schools were randomly exposed to three different treatments. The participants consisted of 129 (47, 41, 41) students. The treatments were one control group with a regular method of teaching, and two experimental groups: a 4C/ID PLE with ICT, and a 4C/ID PLE without ICT. The instructional conceptions questionnaire was administered both in the pre-and the post-test to assess students’ instructional conceptions. Pre- and post-tests contain retention and transfer items. Technical teachers were trained to implement the interventions. In contrast to expectation, findings show no moderating effects of students’ instructional conceptions on the learning environments. Finally, the results indicate that students’ instructional conceptions positively change after implementation of the three interventions. The theoretical, research, and practical implications of the results for the instructional design and technology community as well as educational practice are discussed.  相似文献

The results of Fast ForWord® training on English decoding-related skills were examined. Finnish fifth-grade students were identified as having reading fluency problems and poor skills in English as a foreign language learned at school and were randomly assigned to either a training group (TRG) or a control group. The TRG (n?=?13) received 50?min of daily computer program-based training for a period of approximately 10 weeks. Students in the first control group (n?=?11) received the school’s regular instructional programme. A second control group was composed of 14 average readers. The students’ English skills were examined in pre-test, post-test and follow-up measurements. The TRG students saw an acceleration in decoding-related skills. The educational implications of the results are discussed.  相似文献

This research explores the benefits of service-learning among a group of Midwestern college students. Students enrolled in a section of a Juvenile Delinquency course served as volunteers at a juvenile detention facility and were studied using a pre-test/post-test survey design. This pilot project also included a comparison group of students in a section of the course which did not involve service-learning. The study compared service-learning to non-service-learning students in terms of attitudes regarding juvenile delinquency, punishment, and attributions of criminal behavior. We also examined any possible effects of service-learning on student academic skills, career goals, and comfort level with delinquents. Overall, we found that the service-learning project was a valuable educational tool having a positive impact on a number of student outcomes. We discuss the implications of these findings for service-learning research and practice.  相似文献

Case analysis is often used in early childhood teacher education as a constructivist method for developing students' professional skills and knowledge. Although case-based instruction is popular, the professional literature contains little empirical evidence that it effectively helps students develop professional knowledge. Indeed, some empirical evidence suggests case-based instruction may negatively impact learning, especially for students with limited existing knowledge about children's development. This study compared the child development content knowledge gains of two classes of undergraduate preservice early childhood teachers: those taught child development with case-based instruction and those taught the same content with traditional didactic instruction. The study also sought to determine if students' level of prior knowledge interacted with the type of instruction they received. Results indicated that students with strong prior knowledge out-performed classmates regardless of instructional method (i.e., case-based or didactic instruction). Students at all levels of prior knowledge had similar knowledge gains across both case-based and didactic instruction, but data trends suggest students with the least prior knowledge gained the most knowledge with case-based instruction.  相似文献

A total of 341 Latvian students and eight teachers participated in this study of student self-evaluation and teacher evaluation. Students completed a 12-lesson teacher-directed instructional program on conducting and writing a report of their own experimental research. Sixteen classes were randomly assigned to one of four treatment conditions: (1) no in-program evaluation, (2) self-evaluation and revision at the research design and draft final report stages, (3) teacher evaluation and student revision at both stages, (4) self-plus-teacher evaluation and student revision at both stages. Students in the teacher-evaluation and self-plus-teacher evaluation conditions received significantly higher ratings from an independent rater on their final research reports. However, students under the self-evaluation conditions had greater confidence in their ability to conduct future experiments. This research is based on Dr. Olina's dissertation at Arizona State University, and was supported by grants from the Arizona State University Graduate Research Support Program and the Assessment Training Institute Foundaton in Portland, Oregon. We gratefully acknowledge their support.  相似文献

Students with mathematics learning disabilities (LD) exhibit difficulties with retrieval and cognitive skills that impede their ability to perform basic mathematical skills. Instruction in mathematical procedures (i.e., procedural knowledge) is necessary to help students learn and apply skills such as basic facts and whole-number computation. Division is a skill that is identified in curriculum across the grade levels; yet, it is a skill that is often taught last in instructional sequences because of its complexity and prerequisite knowledge. Reviews of research have revealed that students with LD benefit from a combined model of academic instruction that includes both explicit and strategic instructional procedures. This article presents an overview of division instruction and a sample of interventions for teaching division that include explicit and strategic instructional procedures, which are found in the combined model of teaching.  相似文献

The ability to interpret experimental data is essential to understanding and participating in the process of scientific discovery. Reading primary research articles can be a frustrating experience for undergraduate biology students because they have very little experience interpreting data. To enhance their data interpretation skills, students used a template called “Figure Facts” to assist them with primary literature–based reading assignments in an advanced cellular neuroscience course. The Figure Facts template encourages students to adopt a data-centric approach, rather than a text-based approach, to understand research articles. Specifically, Figure Facts requires students to focus on the experimental data presented in each figure and identify specific conclusions that may be drawn from those results. Students who used Figure Facts for one semester increased the amount of time they spent examining figures in a primary research article, and regular exposure to primary literature was associated with improved student performance on a data interpretation skills test. Students reported decreased frustration associated with interpreting data figures, and their opinions of the Figure Facts template were overwhelmingly positive. In this paper, we present Figure Facts for others to adopt and adapt, with reflection on its implementation and effectiveness in improving undergraduate science education.  相似文献

In most primary science classes, students are taught science inquiry skills by way of learning by doing. Research shows that explicit instruction may be more effective. The aim of this study was to investigate the effects of explicit instruction on the acquisition of inquiry skills. Participants included 705 Dutch fifth and sixth graders. Students in an explicit instruction condition received an eight-week intervention of explicit instruction on inquiry skills. In the lessons of the implicit condition, all aspects of explicit instruction were absent. Students in the baseline condition followed their regular science curriculum. In a quasi-experimental pre-test–post-test design, two paper-and-pencil tests and three performance assessments were used to examine the acquisition and transfer of inquiry skills. Additionally, questionnaires were used to measure metacognitive skills. The results of a multilevel analysis controlling for pre-tests, general cognitive ability, age, gender and grade level indicated that explicit instruction facilitates the acquisition of science inquiry skills. Specifically on the performance assessment with an unfamiliar topic, students in the explicit condition outperformed students of both the implicit and baseline condition. Therefore, this study provides a strong argument for including an explicit teaching method for developing inquiry skills in primary science education.  相似文献

Experimentation is a complex problem-solving process. In biology lessons, experiments involve creative thinking and open discovery; however, they still require some degree of instructional guidance. The right balance between discovery learning and instructional guidance depends substantially on students’ prior knowledge. Students with low prior knowledge in particular might have difficulties with conducting and understanding experiments. Incremental scaffolds might be a valuable tool to meditate between pure discovery and strong guidance while simultaneously taking learners’ individual knowledge and skills into account. In the current study, we examined the effects of incremental scaffolds (IncSc), no scaffolds (NoSc), and worked-out examples (WoEx) on students’ knowledge acquisition while doing inquiry-based experimentation with a special focus on students with low prior knowledge. In a pre-posttest design, 193 students (Mage?=?13.02?±?0.81 years) participated in a four-hour teaching unit on animals’ overwintering strategies. In the pre- and posttest, we assessed the students’ conceptual and procedural knowledge. Our results partially confirmed our hypotheses: Regarding the conceptual and procedural knowledge of all students, incremental scaffolds showed no additional benefit regarding students’ knowledge in the posttest when compared to working with no scaffolds or worked-out examples. For the students with low prior knowledge, working with incremental scaffolds led to higher conceptual and procedural knowledge after the teaching unit than working with worked-out examples.  相似文献

We assessed the impact of teaching methodological aspects of physics on students’ scientistic beliefs and subject interest in physics in a repeated-measurement design with a total of 142 students of upper secondary physics classes. Students gained knowledge of methodological aspects from the pre-test to the post-test and reported reduced scientistic beliefs, both from their own views and from their presumed prototypical physicists’ views. We found no direct impact of teaching on students’ subject interest in physics. As path analysis indicates, this result can be traced back to opposing paths: Lower scientistic beliefs of students attenuate subject interest while lower presumed scientistic beliefs that they hold of physicists foster subject interest. This finding is in accordance with the self-to-prototype matching theory that predicts an impact of the overlap between students’ self-image and their prototypical image on subject interest in physics.  相似文献

A program for teaching 9th graders course content (history) and how they should evaluate information found on the WWW was designed and tested. Goal of the program was to teach content, evaluations skills, and to achieve transfer of these skills to a different domain. In the design of the program the principles of two transfer theories were combined using a design-based research approach. Results revealed that the program improved students’ evaluation behaviour. Compared to the students of the control condition, the evaluation skills of students in the experimental condition improved to a higher level, but did not lead to transfer. Students in the experimental classes scored higher on the final content exam than students in the control class.  相似文献

This study investigated the hypothesis that prompting students to self-assess their interest and understanding of science concepts and activities would increase their motivation in science classes. Students were randomly assigned to an experimental condition that wrote self-assessments of their competence and interest in science lessons or a control condition that wrote summaries of those same lessons. Writing activities were 10?min long and were given approximately once a week for eighteen weeks. Student motivation was assessed via self-report surveys for achievement goals and interest in science before and after the intervention. Students in the experimental condition showed higher endorsement of mastery goals and reported greater situational interest in science topics after the intervention compared to students who summarised the lessons. Increases in situational interest predicted higher individual interest in the domain. Results indicate an instructional practice requiring just 3?hours out of a semester of instruction was sufficient to achieve these effects on motivation in science classes.  相似文献

The purpose of this study was to investigate and compare the impact of Internet Virtual Physics Laboratory (IVPL) instruction with traditional laboratory instruction in physics academic achievement, performance of science process skills, and computer attitudes of tenth grade students. One-hundred and fifty students from four classes at one private senior high school in Taoyuan Country, Taiwan, R.O.C. were sampled. All four classes contained 75 students who were equally divided into an experimental group and a control group. The pre-test results indicated that the students’ entry-level physics academic achievement, science process skills, and computer attitudes were equal for both groups. On the post-test, the experimental group achieved significantly higher mean scores in physics academic achievement and science process skills. There was no significant difference in computer attitudes between the groups. We concluded that the IVPL had potential to help tenth graders improve their physics academic achievement and science process skills.  相似文献
