This study demonstrated that the modality principle applies to multimedia learning of regular science lessons in school settings. In the first field experiment, 27 Dutch secondary school students (age 16–17) received a self-paced, web-based multimedia lesson in biology. Students who received lessons containing illustrations and narration performed better on subsequent transfer tests than did students who received lessons containing illustrations and on-screen text. In the second field experiment, 55 Dutch secondary school students (age 16–17) received similar multimedia programs that allowed more self-pacing and required students to record the time to learn. The illustrations-and-narration group outperformed the illustrations-and-text group on subsequent transfer tests for students who required less time to learn but not for students who required more time to learn. The interaction of learning time spent with modality of presentation on post-test scores was studied. Implications for testing of the robustness of cognitive theory of multimedia learning are discussed.  相似文献

High school biology students (n = 48) were each randomly assigned to one of four groups defined by possible combinations of two teacher vagueness conditions (high vagueness versus low vagueness) and two post-lesson conditions (test, then lesson evaluation versus lesson evaluation, then test). Each group was presented a lesson over the vascular system of angiosperms. After the lesson, each group was tested on comprehension of the material and each group completed a lesson evaluation. Teacher vagueness terms significantly affected student achievement and student perception of lesson effectiveness. These findings are discussed in relation to previous research on teaching clearly.  相似文献

The study investigated the effects of three types of evaluation on preservice teachers’ performance, knowledge and attitudes related to writing lesson plans that incorporate technology. Subjects were randomly assigned to one of the three treatment conditions: teacher-evaluation, self-evaluation or peer-evaluation. All groups completed three class periods of instruction on writing lesson plans, then each subject submitted his/her draft lesson plan. The drafts were evaluated by assigned evaluators (teacher, self or peer), who provided scores and written feedback on a 15-item rubric. Students then revised their lesson plans into final form. All three treatment groups improved their lesson plans significantly from draft version to final version, with the teacher-evaluation group showing significantly greater improvement and writing significantly better final lesson plans than each of the other two groups. Teacher-evaluation and self-evaluation groups had significantly higher scores on a knowledge-based posttest than the peer-evaluation group. Several suggestions are discussed for making further improvements in the self-evaluation and peer-evaluation processes.  相似文献

Students often make little linkage from lesson to lesson on what they learn in the regular classroom. Having them take responsibility for what they are learning is one way of having them think and connect these thoughts together. This qualitative study looks at the use of the World Wide Web (WWW) as a research and teaching tool in promoting self-directed learning in a group of 15 year old students. The perceptions of students on the effectiveness of the World Wide Web in assisting them with the construction of knowledge on Photosynthesis and Respiration are reported and discussed in this paper. The study showed that the students found that the WWW had a number of positive effects on their learning including motivation for independent learning. However, the unedited and unstructured nature of the WWW meant that many of the sites they visited had information that was too difficult to understand and that time was required to improve technical and critical thinking skills to search effectively. The teacher's role as facilitator and guide was crucial to the success of their learning.  相似文献

This study examined the effect of a short-term training programme οn in-service physical education teachers’ behaviour and students’ engagement in learning. Teachers (n = 32) were randomly divided into an experimental and a control group. Each teacher’s behaviour was observed in six lessons; two for each measurement (pre, post and retention) and analysed with qualitative dimensions of lesson introduction, task presentations and lesson closure. Student engagement was analysed with the time analysis form. The total and successful attempts of selected students were also recorded. The experimental group attended a two-hour lecture followed by a two-hour practicum, and showed significant improvement and learning of all the examined behaviours as well as significantly higher performance than the control group. Also, students of the experimental teacher group presented significantly greater activity time, more practice attempts and more successful ones than their peers in the control group. The results establish the effect of the training programme on teacher behaviour and student engagement in learning.  相似文献

Advances in online geospatial technologies (GST) have expanded access to K-12 classrooms which has implications for the support teachers require to effectively integrate GSTs to promote learning. Previous studies have shown the impact of GST-integrated lessons on student engagement, spatial thinking skills, and/or content knowledge; however, most of these studies have been small in scope and scale and frequently focus on the affordances of the technology, without addressing the context of the implementation and student characteristics for whom GST is most impactful. We attempt to address some of these gaps. Our program scaled an effective GST-focused professional learning and development program to a national audience through a facilitator development model. This paper explores the student characteristics and lesson factors that resulted in student interest in science and technology and careers in those fields. After teaching a Geospatial Inquiry lesson created during a teacher workshop, teachers (n = 82) submitted the lessons and surveys on the implementation of Geospatial Inquiry lessons. The implementation surveys and lessons were scored for alignment to the principles of high-quality Geospatial Inquiry. Students (n = 1924) completed a post-lesson retrospective survey and indicated the extent to which their perceptions and attitudes toward science and technology changed because of the lesson. Results indicate that teacher GST performance is associated with increases in student outcomes. Students with previous exposure to science activities were more likely to have increased interest and excitement in science and careers in science but decreased interest in technology careers. Students who had previous exposure to technology activities had increased interest and excitement in technology and careers in technology but decreased interest in science careers. Geospatial Inquiry lessons also had a significant impact on students who are traditionally underrepresented in STEM fields. After participating in the lessons, students who identify as female reported higher engagement and interest in science and higher interest in science careers. Students who identified as Black or Hispanic also reported higher interest and excitement in science and technology, and students who identified as Black reported marginally higher interest in science careers.  相似文献

Singing has been advocated as an efficient supplementary strategy in language teaching, but little is known about its effect on grammar learning. We conducted an intervention study (five lessons) with primary EFL learners (N = 57, mean age = 8.67, SD = 0.60) who were taught new vocabulary and grammar through either singing or speaking lyrics. The control group had new vocabulary introduced during regular lessons. Language gains were assessed through pre-, post-, and follow-up tests; affect was measured after each lesson. Students in the singing group showed similar vocabulary gains to students in the control group and larger gains than students in the speaking group. Importantly, singing students outperformed both groups on spelling and grammar learning. Positive affect was similar across intervention groups, but only the singing group showed significantly enhanced positive affect compared to the control group. Overall, results indicate a potential benefit of singing for grammar learning.  相似文献

Students with disabilities need to be more involved in planning and presenting individualized education program (IEP) meetings, and teachers need an effective, efficient curriculum to teach students how. My IEP curriculum uses folding graphic organizers to teach students to self-direct IEP meetings, targeting self-advocacy and self-determination to combat student apathy toward and passive participation in IEPs. Students who received My IEP (n = 25) spoke on average for 36.78% of IEP meeting time, while comparison group students (n = 14) spoke on average 2.15%. My IEP students recalled significantly more IEP knowledge and had shorter meetings. School faculty and staff were significantly more satisfied with My IEP meetings.  相似文献

High school social studies students (N = 448) were each assigned to one of 16 groups defined by possible combinations of two teacher uncertainty conditions (uncertainty vs. no uncertainty), two teacher “bluffing” conditions (bluffing vs. no bluffing), two lesson discontinuity conditions (discontinuity vs. no discontinuity), and two lecture notes conditions (notes handouts vs. no notes handouts). Each group was presented a lesson about the geography, politics, history, and economy of Botswana. The lessons were the same except for variations in the four conditions stated above. After the lesson, each group was tested on comprehension of the material, and then each group completed a lesson evaluation. Teacher uncertainty negatively affected achievement, and notes handouts positively affected achievement. Both teacher bluffing and lesson discontinuity negatively affected student evaluation of the lesson. Several significant interactions were obtained. These findings are discussed in relation to previous research on low-inference behaviors related to teacher clarity.  相似文献

High school students of various ability levels were presented lessons concerning economics concepts. The lessons were varied according to their organization or structure. Students then were tested over their understanding of the concepts. The test questions ranged from simple recall of information (low level) to application of economics principles (high level). Students scored generally higher when they were presented highly structured lessons. Scores were higher on the low level questions than on the high level questions. Significant interactions occurred between student ability level and lesson structure, as well as between cognitive level of questions and lesson structure. These results are discussed in terms of previous research on lesson structure.  相似文献

Cognitive and affective outcomes of a class visit to a participatory science museum were examined by comparing responses of 416 fifth and sixth graders randomly assigned to four conditions (control, exhibit only, lesson only, and exhibit followed by lesson) and two tests (verbal and visual). Students visiting a simple machines exhibit scored higher on a test of science content than the control group, but lower than the group attending a classroom lesson in the museum. The study did not demonstrate conclusively a cognitive advantage of having the exhibit experience prior to the lesson. Scores on the visual test were consistently higher than scores on the verbal test. Study findings indicate that the particular strength of the science museum exhibit lies in the affective domain. Students found the exhibit much more enjoyable, interesting, and motivational than a classroom lesson. Implications of the findings for science education are discussed.  相似文献

This study explored the impact of individual versus two‐person group testing on graduate students’ achievement and motivation to learn while enrolled in a 16‐lesson educational research methods course. Students in two sections of the course were exposed to the same content and instructional methods, with one exception: students in one section took three professor‐created, criterion‐referenced examinations (during lessons 6, 11 and 16) individually, whereas students in the other section took the same examinations with a partner with whom they could examine and discuss the test items in order to derive a common answer. At the end of the course, the motivation to learn of all students was assessed. Results revealed that students tested with a partner achieved significantly higher scores on two of the examinations and demonstrated significantly higher levels of motivation to learn than did students taking the examinations alone. Qualitative analysis of the students’ written expressions concerning the course and of their comments from group and individual interviews revealed possible explanations for these outcomes.  相似文献

Abstract

The current study examined the effects of a silent rapid reading skills training intervention on the reading rate and reading achievement of primary school students in China in order to determine the efficacy of the intervention and explore potential gender differences. A total of 108 Chinese primary school students were randomly assigned by the classroom to either an experimental (n = 54) or control (n = 54) condition. Students in the experimental group completed 12 sessions of rapid reading skills training designed to increase their ability to rapidly read Chinese text in silence. Students in the control group engaged in regular Chinese language curriculum for the same time period. After the three-week intervention period, students in the experimental group displayed significantly greater silent reading speed of Chinese characters (M?=?1331.26 characters per minute) compared to students in the control group (M?=?617.48 characters per minute; p?<?.001). Children in the intervention group also displayed a significantly greater effective reading rate (F = 87.11, p?<?.001, partial η2?=?0.46) at post-test compared to the control. Male students displayed greater increases in reading speed than female students. Neither intervention effect nor gender difference was evident for reading comprehension. Implications for educational interventions designed to increase silent reading speed among Chinese students are discussed.  相似文献

The effects of studying alone or in cooperative learning groups on high- and average-ability students were investigated. Also examined were the effects of completing computer-based instruction using either a learner- or program-control version of a lesson. A total of 175 fourth-grade students were classified as being of high or average ability and randomly assigned to paired or individual treatments stratified by ability. Students completed training to enhance small-group interaction before completing a computer-based tutorial and a posttest. Following cooperative learning, students demonstrated increased achievement and efficiency as well as better attitudes toward both the computer lesson and grouping. Students completed more practice items and examples in program-control treatments than in learner-control treatments. However, the form of lesson control did not affect students' achievement or attitudes.  相似文献

Cooperative learning is an active learning approach in which students work together in small groups to complete an assigned task. Students commonly find the subject of ‘physical and chemical changes’ difficult and abstract, and thus they generally have many misconceptions about it.

Purpose

This study aimed to investigate the effects of jigsaw cooperative learning activities developed by the researchers on sixth grade students’ understanding of physical and chemical changes.

Sample

Participants in the study were 61 sixth grade students in a public elementary school in Izmir, Turkey.

Design and methods

A pre-test and post-test experimental design with a control group was used, and students were randomly assigned to the experimental and control groups. Instruction of the subject was conducted via jigsaw cooperative learning in the experimental group and via teacher-centered instruction in the control group. During the jigsaw process, experimental group students studied the subjects of changes of state, changes in shape and molecular solubility from physical changes, and acid–base reactions, combustion reactions and changes depending on heating from chemical changes in their jigsaw groups.

Results

The concept test results showed that jigsaw cooperative learning instruction yielded significantly better acquisition of scientific concepts related to physical and chemical changes, compared to traditional learning. Students in the experimental group had a lower proportion of misconceptions than those in the control group, and some misconceptions in the control group were identified for the first time in this study.

Conclusions

Jigsaw cooperative learning is an effective teaching technique for challenging sixth grade students’ misconceptions in the context of physical and chemical changes, and enhancing their motivation, learning achievements, self-confidence and willingness in the science and technology lesson. This technique could be applied to other chemistry subjects and other grade levels.  相似文献

Peer assessment has been increasingly integrated in educational settings as a strategy to foster student learning. Yet little has been studied about how students at different learning levels may benefit from peer assessment. This study examined how peer-assessment and students’ learning levels influenced students’ project performance using a two-way factorial design. One hundred and thirty teacher education students participated in this quasi-experimental study. When working on a technology-integrated lesson plan project, the experimental group completed an online peer assessment process while the control group followed the discussion method. Students’ learning levels were measured and divided into low, average and high achieving according to the quality of their draft lesson plans. Data analysis suggested that the impact of peer assessment on students’ lesson plan project seemed to vary according to students’ learning levels. While low- and average-achieving students showed significantly improved performance right after the integration of a peer assessment model, the model seemed to have had less impact on the performance of high-achieving students. Significance, implications and limitations of findings are discussed.  相似文献

In response to the leaky STEM pipeline, particularly for girls, many schools have introduced integrated STEM (iSTEM) programs to enable students to solve problems using skills from each STEM area and hopefully enhance their interest in continuing with STEM subjects in senior-high school and university. We investigated whether gender differences in students’ perceptions of classroom emotional climate and attitudes to STEM depend on whether students are undertaking iSTEM projects as part of a multidisciplinary curriculum (S, T, E and M) or unidisciplinary curriculum (S, T, E or M) and also whether they attend a government or nongovernment coeducational school. The sample consisted of 256 students in 24 coeducational grade 7–9 classes in 8 government schools and 157 students in 12 coeducational grade 7–10 classes in 6 nongovernment schools. Whereas boys were significantly more positive than girls in perceptions of clarity, motivation, consolidation and attitudes to iSTEM in coeducational government schools, there were no significant gender differences in coeducational nongovernment schools. Students of both genders in government schools were significantly more positive about all aspects of classroom emotional climate and attitudes than students of both genders in nongovernment schools, even after controlling for socioeconomic status. Also, females were slightly more positive about classroom emotional climate and in their attitudes in multidisciplinary STEM classes in government schools. This study suggests that multidisciplinary STEM classes could motivate girls to pursue STEM subjects in senior-high school and at university.

This study examined the use of form and function analogy object boxes to teach second graders (n = 21) animal adaptations. The study used a pretest–posttest design to examine animal adaptation content learned through focused analogy activities as compared with reading and Internet searches for information about adaptations of animals followed by making an informative puppet play. Students participated in six week‐long lesson sets, each addressing adaptations of two animals, which alternated between the two conditions. In the analogy condition, students matched cards explaining form and function analogies of animal body parts or homes to analogous manufactured items. They mapped analogies, thought of alternate manufactured items, and created new analogies. Students scored similarly on material to be taught through both conditions on the pretest, but made significantly higher posttest mean scores (76.1% analogy versus 57.2% traditional condition) with large effect size (partial η2 = 0.58) on animal adaptation content learned through the analogy activities. This study shows the usefulness of form and function analogies in teaching product innovations to second‐grade students, indicating that early childhood students are able to successfully engage in sophisticated analogy activities. Efficacy of the analogy activities was related to objects that focused attention, motivated, and gave concrete representations of concepts; to cards and graphic organizers for organization, connections, and memory; and to complex thinking activities that challenged students and promoted peer interaction.  相似文献
