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

The positive effects of collaborative learning in a face-to-face environment are well known. However, little empirical research exists to determine if such effects transfer to a computer-mediated environment. The purpose of this study was to investigate the effect of computer-mediated collaboration on solving ill-defined problems. Participants first worked through a Web-based instructional program that taught them a four-step problem-solving process. Then they worked in computer-mediated dyads or alone to apply the steps to solve a realistic problem scenario. Results indicated that participants who worked in computer-mediated collaborative dyads performed significantly better than did participants who worked alone. The results also indicated that dyads spent significantly more time than participants in the individual treatment. Both treatment groups had positive attitudes toward working collaboratively, Internet-based instruction, and transfer of problem-solving skills. Implications for the implementation of computer-mediated collaboration in distance learning are discussed. During article preparation, he was a PhD student at Arizona State University (ASU), Tempe.

This article explores the effectiveness of a computer-based spatial learning strategy approach for improving reading comprehension and writing. In reading comprehension, students received scaffolded practice in translating passages into graphic organizers. In writing, students received scaffolded practice in planning to write by filling in graphic organizers and in translating them into passages. Based on a cluster-randomized sampling process, 2,468 students distributed in 12 schools and 69 classrooms participated in the study. Schools were randomly assigned to the computer-based instruction (CBI) group or traditional instruction (TI) group. Teachers assigned to the CBI treatment integrated the applications into the language arts curriculum during one school semester. A standardized test was used to measure reading comprehension and writing. The data were analyzed through a statistical multilevel model. The findings showed that students in the CBI group improved their reading and writing skills significantly more than students under TI—yielding an effect size d = 0.30.  相似文献

A good deal of research has been published concerning the effects of orienting activities on learning. Orienting activities include advance organizers, embedded pre-questions, behavioral objectives, as well as other strategies designed to prepare the learner for instruction. This paper focuses on the presumed functions of orienting activities and the implications of such functions for the design of computer-based interactive video. In addition, the application of empiricallyfounded principles in the design and production of computer-based interactive video is described.Grumman Aerospace Corporation  相似文献

This study investigated the effects of cooperative group composition, student ability, and learning accountability on achievement, interaction, and instructional efficiency during computer-based instruction. A total of 125 sixth- and seventh-grade students were randomly assigned to heterogeneous or homogeneous dyads. Groups were designated as having either group or individual account-ability for mastery of lesson content. Cooperative dyads completed a tutorial on a novel symbolic mathematics topic, featuring basic symbol learning and application of the symbols. Indicators of ongoing cooperation were collected during instruction. Five days later, students completed a posttest. Low-ability students interacted more and completed the instruction more efficiently in heterogeneous than in homogeneous groups. High-ability students completed the instruction more efficiently in homogeneous than in heterogeneous groups. Cooperation was significantly related to achievement for heterogeneous ability groups, but not for either homogeneous high- or low-ability students.  相似文献

Cooperative learning in computer-based instruction   总被引：1，自引：0，他引：1  
High equipment and materials costs, limited access to computers for instruction in many schools, and the success of cooperative learning strategies in traditional classroom instruction have prompted researchers to examine the potential of cooperative computer-based instruction (CBI). In this article, recent research on cooperative CBI is reviewed and findings related to achievement, patterns of study, social interchange, motivation, and gender are discussed. In addition, guidelines on the implementation of cooperative CBI that have been gleaned from the literature are presented.This paper was prepared with partial support from MECC/University of Minnesota Center for Study of Educational Technology, and presented at the AECT Annual Convention, January 31–February 4, 1990, Anaheim, CA.  相似文献

An Integrated Learning System (ILS) is an advanced computer-based instructional system, generally consisting of a set of computerized courseware covering several grade levels and content areas, and complex classroom management and reporting features. Although ILSs have become increasingly popular in schools over the past five to ten years, they introduce several potential factors that could have negative effects on students' academic and social growth. These factors include: (a) de-emphasis of affective outcomes and increased student isolation, (b) lack of teacher involvement in curriculum planning and delivery, and (c) disparate effects on student achievement based on students' academic level. One possible strategy for addressing these concerns is integrating cooperative learning with ILS instruction. This paper will examine the research dealing with integrating cooperative learning strategies and computer-based instruction and provide guidelines and strategies for designing ILS instruction that enhances opportunities for cooperative learning.Thomas A.

The purpose of this study was to determine what effect the communication of precise instructional objectives to students has on their learning. The study was designed (1) to provide data on whether student achievement can be influenced significantly by providing students, in advance of instruction, information on what is expected of them as an outcome of instruction and (2) to investigate various ways of communicating to students, in writing, that which is to be learned in class. The Ss for this study were selected from five tenth-grade health and safety classes taught by the same teacher. Of the 143 Ss, one third in each class was randomly assigned to one of three treatment groups. For treatment groups one through three, the participants received precisely stated instructional objectives, vaguely stated instructional objectives, and short paragraphs of health information, respectively. Ss receiving prior to instruction precise information on what is expected of them showed greater achievement than those who received vague or related information.  相似文献

The purpose of this study was to investigate the effects of verbal interaction cues and ability grouping within a cooperative learning computer-based program. We blocked 231 eighth graders in a required science class by ability and randomly assigned them to homogeneous lower-ability, homogeneous higher-ability, or heterogeneous mixed-ability dyads. Each dyad was randomly assigned to a computer program that either did or did not contain verbal interaction cues designed to facilitate summarizing and explaining between partners. Results indicated that students using the cued version of the program performed significantly better on the posttest than students using the noncued version. Direct observation of student interaction indicated that students in cued dyads exhibited significantly more summarizing and helping behaviors than noncued students. Furthermore, higher-ability dyads exhibited significantly less off-task behavior than the other dyads. Implications for designing computer-based instruction for cooperative settings are provided.  相似文献

Twelve students with low-incidence disabilities were observed in their kindergarten through third grade, general education classrooms. Frequency data were collected on the number of teaching opportunities delivered on the learning objectives reflected in the students’ Individual Education Programs, the individual who delivered the teaching opportunity, and the instructional context that was occurring at the time the teaching opportunity occurred. Results indicated that teaching opportunities on the learning objectives occurred at an overall rate per minute of 0.224 and 4 students received no teaching opportunities. The general education teacher and special education assistant delivered the most instruction in 1:1 instructional contexts. Results are discussed in relation to improving the quality of instruction when students with disabilities are included in general education classrooms.  相似文献

In this study, the performance and attitudes toward instruction of learners working individually on a computer-based sex education lesson were compared with those of learners working cooperatively in dyads. A tatal of 60 eighth-graders received treatments that either required individual work or encouraged cooperation with a partner. Results indicated that students who worked cooperatively significantly outperformed those who worked individually. On an attitude measure, interactions were detected between instructional method and gender, as well as among instructional method, gender, and ability. High-ability males and females reported comparable attitudes toward each instructional method, but ratings for low-ability students were differentiated according to instructional method: Low-ability males responded most favorably, while low-ability females responded least favorably to individualized methods, and low-ability females responded most favorably and low-ability males least favorably to cooperative methods.  相似文献

Does the specific structure of advance organizers influence learning outcomes? In the first experiment, 48 psychology students were randomly assigned to three differently structured advance organizers: a well-structured, a well-structured and key-concept emphasizing, and a less structured advance organizer. These were followed by a sorting task, a text study phase, and a posttest. The results indicated that differently structured advance organizers lead to different proto-schemata before and different learning outcomes after the text study phase. The second experiment replicated and extended these findings with 53 mathematics students. As in experiment 1, three differently structured advance organizers were used; but to rule out alternative explanations, the sorting task between the advance organizer and the text study phase was omitted. The results showed strong beneficial effects of well-structured advance organizers on near and far transfer tasks. Taken together, both experiments support the claim that the structure of advance organizers has an effect on preliminary schemata and learning outcomes. On a general level, the results indicate that advance organizers can support the generation of proto-schemata and thus can be more than the activation of “existing” concepts in long-term memory. With regard to education, this implies that educators should not only think about whether prior domain-specific knowledge is present, but also about how to scaffold the generation of proto-schemata at the beginning of instruction.  相似文献

Active‐learning labs for two topics in high school biology were developed through the collaboration of high school teachers and university faculty and staff and were administered to 408 high school students in six classrooms. The content of instruction and testing was guided by State of Texas science objectives. Detailed teacher records describing daily classroom activities were used to operationalize two types of instruction: active learning, which used the labs; and traditional, which used the teaching resources ordinarily available to the teacher. Teacher records indicated that they used less independent work and fewer worksheets, and more collaborative and lab‐based activities, with active‐learning labs compared to traditional instruction. In‐class test data show that students gained significantly more content knowledge and knowledge of process skills using the labs compared to traditional instruction. Questionnaire data revealed that students perceived greater learning gains after completing the labs compared to covering the same content through traditional methods. An independent questionnaire administered to a larger sample of teachers who used the lab‐based curriculum indicated that they perceived changing their behaviors as intended by the student‐centered principles of the labs. The major implication of this study is that active‐learning–based laboratory units designed and developed collaboratively by high school teachers and university faculty, and then used by high school teachers in their classrooms, can lead to increased use of student‐centered instructional practices as well as enhanced content knowledge and process learning for students. © 2007 Wiley Periodicals, Inc.

Structured collaborative learning activities undertaken in two graduate level classes are described. Student and instructor perspectives on these activities are explored based on data collected through interviews, open-ended evaluation instruments, and journals. Four perspectives on collaborative learning emerged from the data: (1) student expectations; (2) instructor tolerance for ambiguity and flexibility; (3) student reliance on authority; and, (4) evaluation of student learning. Suggestions for implementing collaborative groups in graduate courses are presented.Julie A.

Structuring cooperative learning activities has been shown to be an effective technique for integrating handicapped and nonhandicapped students. Previous research in this area has focused on the relative effects of cooperative versus competitive and individualistic learning situations upon peer relations and academic achievement. Few investigations have examined the various elements within the cooperative learning model that appear to promote positive peer interactions among handicapped and nonhandicapped students. The present study evaluated the influence of collaborative skill instruction versus no collaborative skill instruction on the social interaction behaviors of moderately/severely handicapped and nonhandicapped students participating in group science activities. These data reveal that students receiving collaborative skill instruction interacted more positively with one another than those who did not receive the instruction.  相似文献

This article summarizes the findings of research studies designed to improve the comprehension of expository text for students with learning disabilities. Twenty-nine studies were located that met the inclusion criteria. Interventions gleaned from the review were categorized as content enhancement (i.e., advance and graphic organizers, visual displays, mnemonic illustrations, and computer-assisted instruction) or cognitive strategy instruction (i.e., text structure, main idea identification, summarization, questioning, cognitive mapping, reciprocal teaching). Treatment outcomes are discussed in relation to the various instructional approaches, student characteristics (e.g., grade, IQ), instructional features (e.g., materials, treatment length), methodological features, strategy maintenance, and generalization components. Implications for classroom practice and future research directions are provided.  相似文献

Research indicates that cooperative learning with teacher‐guided instruction is more effective in helping young children to learn than cooperative learning with minimal guidance. In the present study, two different cooperative learning activities (jigsaw and drama) and a control condition (a traditional teacher‐led approach) were compared. The participants were 279 Grade 5 Hong Kong students located in nine classrooms. The two experimental conditions emphasised teachers' cognitive support in helping students to understand a text through both teacher‐led and student‐led activities. Post‐test data included a reading comprehension test and three questionnaires that investigated students' goal orientations, initial level of relative autonomy and perceptions of instructional practices. Findings indicate that students in the jigsaw group outperformed students in both the drama group and the control group in the reading comprehension test. The implications of conducting cooperative learning activities with well‐planned teacher guidance are discussed.  相似文献

Two studies were conducted to investigate the effects of cooperative learning on second‐graders’ motivation and learning from text. In Study 1, students (n = 160) in cooperative learning groups were compared with their counterparts (n = 107) in traditional instruction groups. The results revealed a statistically significant difference between the two groups, with more favourable perceptions of teachers’ instructional practices and better reading comprehension in the instructional intervention groups than in the traditional instruction groups. In Study 2, 51 second‐graders participated in the instructional intervention programme. The results showed that students’ positive cooperative behaviour and attitudes were related to their motivation and reading comprehension. When students perceived that their peers were willing to help each other and were committed to the group, they tended to be more motivated and performed better in reading comprehension.  相似文献

The purpose of this study was to investigate the effect of informal cooperative learning and the affiliation motive on achievement, attitude, and student interactions. Participants classified as high or low need for affiliation used either an informal cooperative learning strategy or an individual strategy while receiving information, examples, practice and feedback from an instructional television lesson. Results indicated that participants who used the individual strategy acquired significantly more knowledge from the lesson and indicated significantly more continuing motivation for working alone than those who used the informal cooperative strategy. Instructional strategy did not influence performance on the application portion of the test. Results also revealed that high affiliation participants expressed significantly more continuing motivation than low affiliation participants for working with another person. Low affiliation participants expressed significantly more continuing motivation than high affiliation participants for working alone. Finally, results indicated that high affiliation dyads exhibited significantly more on-task group behaviors (taking turns, sharing materials, group discussion of content) and significantly more off-task behaviors than low affiliation dyads.

In an experiment designed to investigate individual differences in learning from written materials preceded by advance organizers, 89 fourth-grade subjects were randomly assigned to treatment conditions in which programmed material on insects was preceded by one of three introductory passages containing: (1) higher level generalizations and specific examples; (2) higher level generalizations without examples; or (3) a control passage. Membership in treatment groups was determined by random assignment. Criterion performances were immediate and delayed posttest performance and errors during instruction. Analysis of variance results of treatment effects showed that the three treatments were about equally effective in terms of promoting retention and program errors. Simple regression analysis of Aptitude × Treatment interactions disclosed that Otis-Lennon IQ scores interacted significantly with instructional treatments for program errors showing a negative relationship between IQ scores and the degree of structure provided by the advance organizers.  相似文献
