The purpose of this study was to examine the combined effects of orienting activities and levels of practice on learning from interactive video. Participants were 72 college students. Each participant was randomly assigned to an orienting activity group and to one of three practice groups: No Practice, Limited Practice, or Elaborate Practice. The lesson, which focused on characteristics of various artists and art periods, included practice for one half of the facts and applications cued initially via the orienting activity. The posttest included both new and repeated items for both facts and applications taught during the lesson. Results indicated significant main effect differences related to item familiarity and practice. In addition, interactions were detected between type of learning and practice, and item familiarity and practice.  相似文献

The purpose of this study was to investigate the effect of orienting activities and type of practice on achievement, continuing motivation, and student behaviors in a cooperative learning environment. Eighty graduate education majors were assigned to cooperative groups and required to learn instructional design principles from three instructional television lessons. Each lesson included specific orienting activities (advance organizers or objectives) and different types of practice (verbal information or intellectual skills). Results indicated that subjects who worked in groups that received intellectual skills practice performed better on the application portion of the posttest than those who received verbal information practice. Knowledge acquisition and student behaviors were affected by a combination of type of practice and orienting activity. Groups that received intellectual skills practice discussed more content, gave more help to their fellow group members, and exhibited less individual behavior than groups that received verbal information practice. Groups given objectives discussed significantly more content than groups given advance organizers. The authors wish to thank Steven Ross and the reviewers ofETR&D for their helpful comments on an earlier draft of this paper.  相似文献

This article focuses on improving the instructional quality of student teachers in elementary education. We developed a coaching approach involving classroom observation and appropriate lesson preparation and feedback templates. Using an untreated control group design with pre-test and posttest (n = 198), we answered the question ‘whether student teachers who learned to teach with the new coaching approach achieved a higher level of pedagogical and didactical teaching skills compared to student teachers who did not receive this approach’. The effect variable used was the observation instrument ICALT. We compared the average scores of the control group and the experimental group on the posttest (ANCOVA). The differences found on the posttest, after controlling for the confounding variables, were significant on all ICALT scales. These effect sizes are medium on the scales; ‘Safe climate’, and ‘Clear instruction’, and large on the scales; ‘Classroom management’, ‘Activating pupils’, ‘Adaptive teaching’, and ‘Teaching learning strategies’.  相似文献

Recommendations for the design of interactive video materials are often based on the premise that interactive video may overcome learners' preconceptions of television as “easy.” This study investigated learner preconceptions of the difficulty of interactive video, instructional television, and television, and examined the effects of actively or covertly responding to practice questions on perceived mental effort, recall, and inferences. Seventy-one undergraduate students completed a questionnaire assessing their preconceptions of the difficulty of the three media, received their treatment, completed a questionnaire assessing perceived mental effort, then completed a recall and inference posttest. Before the lesson, the learners perceived it to be significantly easier to learn from interactive video than from instructional television and television, and significantly easier to learn from instructional television than from television. There were no significant differences in the mental effort ratings or inference scores among the three groups. The interactive video group recalled significantly more information than the television group. Possible reasons for findings and suggestions for further research are discussed.  相似文献

This study examined changes in student motivation and achievement in science during a visit to a university children’s science museum. The study was based on the pretest–posttest control comparison group design with four treatment groups: control, exhibit, lesson and exhibit/lesson. The sample consisted of 228 sixth-grade students from a Louisiana public school who were randomly assigned to one of the four experimental groups. Pretest, posttest and delayed posttest measures of intrinsic motivation and achievement in science were obtained using the Children’s Academic Intrinsic Motivation Inventory and an achievement test written to measure areas of science incorporated in the museum exhibits. The data were analysed using a one-way ANOVA, dependent t tests and Pearson r. Significant differences were found within groups for (1) the lesson group in motivation and (2) the exhibit group in achievement from pretest to posttest and from posttest to delayed posttest. A significant relationship between level of motivation and science achievement was revealed for the exhibit group on the delayed posttest. There were no other significant findings to support that the treatment led to any long-term effects on motivation or achievement within any of the four experimental groups.  相似文献

This study investigated the effects of an inductive versus a deductive instructional approach on the constructive feedback and problem-solving skills of supervisors. Sixteen supervisors were randomly assigned to either an inductive or a deductive instructional group for one of the instructional units in a supervisory training program. The topic of the unit was the constructive feedback process. Supervisors' acquisition and transfer of skill in giving constructive feedback, problem-solving skill, facilitation of subordinate problem-solving skill, and attitudes toward training were assessed. The findings showed that while supervisors in the deductive group demonstrated greater ability to transfer their learning, supervisors in the inductive group perceived that the quality of their training experience was better. No significant differences were found on either measure of problem-solving skill. Implications of these findings for instructional design theory, research, and practice are discussed.  相似文献

This study investigated the effects of domain-general and domain-specific scaffolds with different levels of support, continuous and faded, on learning of scientific content and problem-solving. Students’ scores on a multiple-choice pretest, posttest, and four recommendation forms were analyzed. Students’ content knowledge in all conditions significantly increased from pretest to posttest. However, the continuous domain-specific condition outperformed the other conditions on the posttest. Although domain-general scaffolds were not as effective as domain-specific scaffolds on learning content and problem representation, they helped students develop solutions, make justifications, and monitor learning. Unlike domain-specific scaffolds, domain-general scaffolds helped students transfer problem-solving skills when they were faded. Several suggestions are discussed for making improvements in the design of scaffolds to facilitate ill-structured problem solving.  相似文献

This study compares the effects of two methods of teaching—teacher-centered and cooperative learning—on students’ science achievement and use of social skills. The sample consists of 163 female elementary science students in 8 intact grade 5 classes who were assigned to 2 instructional methods and were taught an identical science unit by 4 classroom teachers. The students’ science achievement was measured by a researcher-designed achievement test given to students as a pretest and a posttest. Students’ social skills were determined by a researcher-designed survey administered as a pretest and posttest. Analysis of the achievement test scores and the social skills survey responses revealed that cooperative learning strategies have significantly (p > 0.05) more positive effects on both students’ achievement and social skills than teacher-centered strategies. These results provide an evidential base to inform policy decisions and encourage and persuade teachers to implement cooperative learning methods in Kuwaiti classrooms.  相似文献

The purpose of this study is to assess students’ conceptual learning of electricity and magnetism and examine how these conceptions, beliefs about physics, and quantitative problem-solving skills would change after peer instruction (PI). The Conceptual Survey of Electricity and Magnetism (CSEM), Colorado Learning Attitudes about Science Survey (CLASS), multiple-choice test was administered as a pre- and posttest with Solomon 4 group design to students (N  =  138) enrolled on freshman level physics course. The number of chapter taught to the students was 14. Problem-solving strategy steps were asked to students in the exam. The analyses of CSEM showed that the treatment group (g  =  0.62) obtained significantly higher conceptual learning gain than the control group (g  =  0.36). The conceptual understanding and problem-solving skills of the students on magnetism considerably enhanced when PI was conducted (37% and 20%, respectively). CLASS results for 5 subscales (conceptual understanding, applied conceptual understanding, problem solving general, problem solving confidence, and problem solving sophistication) supported the findings of CSEM.  相似文献

Colour is a common feature in computer‐aided learning (CAL), though the instructional effects of screen colour are not well understood. This investigation considers the effects of different CAL study tasks with feedback on posttest performance and on posttest memory of the lesson colour scheme. Graduate students (n=68) completed a computer‐based vocabulary lesson that included either multiple‐choice or constructed‐response study tasks with feedback. Each lesson section used a different colour theme, while the posttest did not use colour. The constructed‐response study task was a little more effective for posttest memory of lesson content but was substantially less effective for posttest memory of the lesson colour scheme. These results show a clear interaction of screen colour and lesson study task, a memory‐context effect. The practical and theoretical implications of these findings are discussed.  相似文献

This paper discusses a qualitative study which examined students’ problem-solving, metacognition, and motivation in a learning environment designed for teaching educational technology to pre-service teachers. The researchers converted a linear and didactic learning environment into a new open learning environment by contextualizing domain-related concepts and skills and providing ill-structured, collaborative problem-solving opportunities. The intervention called Learning Environments Approaching Professional Situations (LEAPS) took into account issues surrounding motivation and situativity that are of particular interest to instructional developers and design-based researchers. In this study, four classes were assigned as either traditional or LEAPS environments from which four cases were selected for further examination. The results suggested that the LEAPS approach was beneficial in supporting students’ problem-solving, motivation, and self-reflections, but only under specific conditions. The implications for instructional design and motivation are discussed.  相似文献

The Direct-instruction Model favors the use of teacher explanations and modeling combined with student practice and feedback to teach thinking skills. Using this paradigm, this study incorporates e-learning during an 18-week experimental instruction period that includes 48 preservice teachers. The instructional design in this study emphasizes scaffolding, observational learning, mastery of critical-thinking skills, guided practices, cooperative learning, providing feedback, self-reflection, online discussions, and active participation in an online learning community. This study employs 2 critical-thinking tests, 2 inventories, and 1 open-ended reflection questionnaire; and students’ scores on the pretest and posttest are compared via the Repeated Measure Analysis of Variance. The primary findings are as follows: (a) all participants preferred the instructional design in this study; (b) the experimental instruction effectively improved the preservice teachers’ critical-thinking ability as well as their professional knowledge and personal teaching efficacy concerning critical-thinking instruction; (c) the mechanisms contributing to the effectiveness of the experimental instruction mainly included discussing and sharing, observational learning, self-reflection, guided practice, and the learning community.  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

Although researchers in undergraduate science, technology, engineering, and mathematics education are currently using several methods to analyze learning gains from pre- and posttest data, the most commonly used approaches have significant shortcomings. Chief among these is the inability to distinguish whether differences in learning gains are due to the effect of an instructional intervention or to differences in student characteristics when students cannot be assigned to control and treatment groups at random. Using pre- and posttest scores from an introductory biology course, we illustrate how the methods currently in wide use can lead to erroneous conclusions, and how multiple linear regression offers an effective framework for distinguishing the impact of an instructional intervention from the impact of student characteristics on test score gains. In general, we recommend that researchers always use student-level regression models that control for possible differences in student ability and preparation to estimate the effect of any nonrandomized instructional intervention on student performance.  相似文献

The aim of this study is to investigate the efficiency of cooperative learning on preschoolers’ verbal mathematics problem-solving abilities and to present the observational findings of the related processes and the teachers’ perspectives about the application of the program. Two experimental groups and one control group participated in the study. Results found that preschoolers in the experimental groups experienced larger improvements in their problem-solving abilities than those in the control group. Findings also revealed that the cooperative learning method can be successfully applied in teaching verbal mathematics problem-solving skills during the preschool period. The preschoolers’ skills regarding cooperation, sharing, listening to the speaker and fulfilling individual responsibilities in group work improved. The teachers’ points of view also supported these findings.  相似文献

According to cognitive load theory, using worked examples is an effective and efficient instructional strategy for initial cognitive skill acquisition for novice learners, as it reduces cognitive load and frees up cognitive resources to build task competence. Contrary to this, productive failure (as well as invention learning, desirable difficulties and other problem-solving-first) frameworks suggest that scaffolded problem-solving activities (a generation phase) preceding explicit instruction enhance learners’ performance. The reported experimental study investigated the effectiveness of different levels of instructional guidance provided to students during the learning phase preceding explicit instruction in standard solution procedures in enhancing students’ engagement and transfer problem-solving skills. Specifically, the study compared partially-guided or unguided attempts at generating problem solutions as opposed to comprehensive guidance, in the form of a worked example. Levels of experienced cognitive load and learner motivation were evaluated in addition to delayed post-test performance scores. There were no differences between the three groups on the transfer post-test outcomes, even though the condition with fully-guided worked examples prior to the explicit instruction expectedly reduced cognitive load relative to the conditions without such guidance. There were also differences between the conditions on some sub-dimensions of the motivation scale. In general, the findings indicate that similar overall outcomes (delayed transfer performance) could be achieved by different sequences of instructional tasks aimed at achieving different sets of specific goals.  相似文献

It is widely recognized that metacognition is an important mediator for successful and high-level learning, especially in higher education. Nevertheless, a majority of higher education students possess insufficient metacognitive knowledge and regulation skills to self-regulate their learning adequately. This study explores the potential of reciprocal peer tutoring to promote both university students’ metacognitive knowledge and their metacognitive regulation skills. The study was conducted in a naturalistic higher education setting, involving 67 students tutoring each other during a complete semester. A multi-method pretest–posttest design was used combining a self-report questionnaire, assessing students’ metacognitive knowledge and their perceived metacognitive skilfulness, with the analysis of think-aloud protocols, revealing students’ actual use of metacognitive strategies. Results indicate no significant pretest to posttest differences in students’ metacognitive knowledge, nor in their perception of metacognitive skill use. In contrast, significant changes are observed in students’ actual metacognitive regulation. At posttest, students demonstrate significantly more frequent and more varied use of metacognitive regulation, especially during the orientation, monitoring, and evaluation phases. Furthermore, our findings point to an increase in more profound and higher-quality strategy use at posttest.  相似文献

This study investigated the learning-from-practice skills that pre-service teachers possess when they enter teacher preparation programs in the United States. Two subskills were hypothesized to represent, at least in part, what is required to learn from practice: (1) the ability to collect evidence about students’ learning in order to analyze the effects of instruction, and (2) the ability to use the analysis to revise the instruction. Because it seems likely that different teaching situations and contexts reveal these learning-from-practice skills in different ways and to different degrees, this study examined the skills that pre-service teachers exhibited under two experimental conditions. Thirty pre-service teachers were asked to analyze the effects of a videotaped mathematics lesson on student learning, to support their analysis with evidence, and to use their analysis to revise the lesson. Based on the results, it appears that many entry level pre-service teachers can carry out a cause-effect type of analysis of the relationships between specific instructional strategies and students’ learning, and can use this analysis to make productive revisions to the instruction. However, prospective teachers’ ability to collect evidence that supports their analysis appears to be less developed. In addition, the type of analysis that prospective teachers carried out about the effects of instruction on students’ learning differed dramatically across the two experimental task conditions.Preparation of this article was supported by the National Science Foundation (Grant #0083429 to the Mid-Atlantic Center for Teaching and Learning Mathematics).

The purpose of this study was to investigate the effect of cooperative learning and the need for affiliation on performance, time on task, and satisfaction. Subjects used either a cooperative or individual learning strategy while receiving information, examples, practice, and feedback from an instructional television lesson. Results indicated that subjects who worked cooperatively spent more time working on practice exercises and reported greater satisfaction than those who worked individually. In addition, results revealed an interaction between instructional method and the need for affiliation. Performance of subjects with a high need for affiliation who worked alone was lower than that of all other groups when subjects were asked to apply what they had learned from the lesson. Implications for employing cooperative groups in settings that were originally designed for individual learning are provided.  相似文献
