Using 1025 junior secondary class three (ninth grade) students and twelve science teachers, this study investigated the effects of cooperative, competitive, and individualistic science laboratory interaction patterns on students' achievement in science and the level of acquisition of practical skills. A 3 × 3 (interaction pattern by ability) factorial model was employed for data gathering. Significant main and interaction effects were found for both dependent measures. The cooperative group was found to be superior on the achievement measure with no difference between the competitive and individualistic groups. The competitive group, however, outperformed the others in practical skills. Additional data indicated that the mixed ability cooperative group did significantly better than the mixed ability competitive group in achievement but not in practical skills. In sum these data are supportive of the differential effects of cooperative, competitive, and individualistic goal structures on cognitive and psychomotor tasks. Results are discussed in terms of their implications for more productive science laboratory work. 相似文献

Aptitude treatment effects of laboratory grouping method for students of differing reasoning ability
This study examines aptitude treatment effects in an inquiry/learning cycle based physical science class for elementary education majors. The aptitude was formal reasoning ability and the students were arranged into three groups: high, middle, and low ability reasoners. The treatment was method of forming groups to work in the laboratory. Students in each of three classes were grouped according to reasoning ability. In one class the laboratory groups were homogeneous, i.e., students of similar reasoning ability were grouped together. In the second class the students were grouped heterogeneously, i.e., students of different reasoning ability were grouped together. In the third class, the student choice pattern, the students chose their own partners. The findings were that there were no aptitude treatment interaction for achievement or for gain in formal reasoning ability, that grouping students of similar cognitive ability together for laboratory work in the class was more effective in terms of science achievement than grouping students of differing cognitive ability together or than allowing students to choose their own partners, and that students at different levels of reasoning ability experienced differential gains in that ability over the semester. 相似文献

Twelve pupils from each of thirteen middle school science classes participated in the study. Measures were obtained for each pupil on nine engagement modes. Two engagement measures, attending and generalizing, together with formal reasoning ability, were related to process skill achievement and retention. Formal reasoning ability was the strongest predictor of process skill achievement and retention, accounting for approximately 36% of the variance in each case. Formal reasoning ability and locus of control were each correlated with specific engagement modes. Formal reasoning ability was positively related with rates of generalizing and comprehending. Locus of control was significantly related with rates of attending and total engagement. 相似文献

The effects of instruction and achievement on science question level for high and low science topic interests were investigated. Eight seventh‐grade classes were randomly assigned to two treatments: instruction and no instruction on researchable questioning. Each student completed the Middle School Students' Science Topic Interest Rating Scale (test‐retest reliability, r = .84); selected two topics in which she or he was least interested and two topics in which she or he was most interested; wrote questions for each topic; and took the Stanford Achievement Tests in reading, mathematics, and science. The questions were rated using the four levels described by the Middle School Students' Science Question Rating Scale (interrater reliability, r = .96). The scores for each question were averaged for two raters, then summed for each interest level for each student. The data were analyzed for main and interaction effects using general linear modeling procedures. Question level was modeled with one within‐subjects factor (science topic interest) and four between‐subjects factors (instruction and three achievement scores). The results indicate that students who received instruction outperformed those students who were not instructed; and high achievers in mathematics, reading, or science outperformed low achievers. There were no interaction effects. © 2000 John Wiley & Sons, Inc. J Res Sci Teach 37: 210–224, 2000 相似文献

Abstract Motivation differences of gender, science class type (biological vs. physical), and ability level of 242 high school students were investigated. High achievers and physical science students had higher scores than did low achievers and biological science students on academic goals, valuing science, and perceived ability. Boys had higher scores than did girls on perceived ability and stereotyped views of science. For only a subset of variables, these main effects were moderated by class type using achievement-level interaction. The class type main effect was moderated by gender in only one instance. Gender did not interact with achievement level for any variable. Instructional implications are discussed. 相似文献

The attitudes towards science of upper‐primary students in three ability strands (average, above average, and gifted) were investigated. A total of 580 upper primary students from co‐educational government and government‐aided schools in Singapore were involved in this study. The attitude subscales investigated were enjoyment of science, preference for science careers, and appreciation of the social implications of science. Gender and ability were found to have statistically significant effects on the variations in the mean score for each attitude subscale. Boys, in general, had more positive views about science than girls. Overall, above‐average and gifted students had comparable attitudes towards science; both of them consistently showed more positive attitudes than average ability students. At least 18% of the sample, with greater percentage being boys, reported “not sure” responses in 50% or more of the total attitude items. © 2008 Wiley Periodicals, Inc.

Informal learning experiences have risen to the forefront of science education as being beneficial to students' learning. However, it is not clear in what ways such experiences may be beneficial to students; nor how informal learning experiences may interface with classroom science instruction. This study aims to acquire a better understanding of these issues by investigating one aspect of science learning, scientific reasoning ability, with respect to the students' informal learning experiences and classroom science instruction. Specifically, the purpose of this study was to investigate possible differences in students' scientific reasoning abilities relative to their informal learning environments (impoverished, enriched), classroom teaching experiences (non-inquiry, inquiry) and the interaction of these variables. The results of two-way ANOVAs indicated that informal learning environments and classroom science teaching procedures showed significant main effects on students' scientific reasoning abilities. Students with enriched informal learning environments had significantly higher scientific reasoning abilities compared to those with impoverished informal learning environments. Likewise, students in inquirybased science classrooms showed higher scientific reasoning abilities compared to those in non-inquiry science classrooms. There were no significant interaction effects. These results indicate the need for increased emphases on both informal learning opportunities and inquiry-based instruction in science. 相似文献

Present instructional trends in science indicate a need to reexamine a traditional concern in science education: the readability of science textbooks. An area of reading research not well documented is the effect of color, visuals, and page layout on readability of science materials. Using the cloze readability method, the present study explored the relationships between page format, grade level, sex, content, and elementary school students ability to read science material. Significant relationships were found between cloze scores and both grade level and content, and there was a significant interaction effect between grade and sex in favor of older males. No significant relationships could be attributed to page format and sex. In the area of science content, biological materials were most difficult in terms of readability followed by earth science and physical science. Grade level data indicated that grade five materials were more difficult for that level than either grade four or grade six materials were for students at each respective level. In eight of nine cases, the science text materials would be classified at or near the frustration level of readability. The implications for textbook writers and publishers are that science reading materials need to be produced with greater attention to readability and known design principles regarding visual supplements. The implication for teachers is that students need direct instruction in using visual materials to increase their learning from text material. Present visual materials appear to neither help nor hinder the student to gain information from text material. 相似文献

This study aimed to compare student science performance between hands-on and traditional item types by investigating the item type effect and the interaction effect between item type and science content domain. In Shanghai, China, 2404 ninth-graders from six urban junior high schools took part in the study. The partial credit many-facet Rasch measurement analysis was used to examine the instrument's quality and investigate the item type effect and the interaction effect. The results showed that the traditional item type was significantly more difficult for participants than the hands-on item type, exhibiting a moderate-to-large effect size. Moderate or large interaction effects of an item type with a specific content domain on student science performance were also detected. Students performed better on some science content domains with a particular item type (either hands-on or traditional). Implications for assessment developers and science instructors were also discussed. 相似文献

Ninety-eight children were observed for 6-min periods on each of 10 days during 50-min, small-group classes in either mathematics, science, geography, or language usage. Two student behaviors (on-task behavior and accuracy of responding to teacher-directed questions) and three types of teacher reinforcement (verbal reinforcement for on-task behavior and accurate responding and tangible reinforcers) were coded during each observation period. A post-test of achievement, directly related to the content of the lessons, was administered at the end of the 10 days of instruction. The causal effects of student behaviors, teacher reinforcement, and student ability (reading achievement and intelligence) on achievement were evaluated using path analysis. The strongest effects were from student ability measures, with accurate responding by students and teacher reinforcement of accurate responding exhibiting smaller, but significant effects. Findings are discussed to qualify the relationship between overt classroom behaviors and degree of learning and the mediating effects of student ability. 相似文献

Secondary 5 students from four schools in Hong Kong were required to classify 18 paper and pencil physics problems in terms
of whether the problems contain necessary and sufficient, missing or irrelevant information for their solution. Students'
ability to denote missing information correlated rather highly with the solution rates of the problems. In another test, students
were asked to classify whether the problems in each of six pairs were similar to or different from each other according to
students' self-determined criteria. Students who used a deep structure (i.e. used the underlying physics principles) to classify
the problems have significantly higher scores in detecting missing and irrelevant information and in the solution rates than
those who used surface structure or features for classification. It is argued that a student who is able to identify what
information is sufficient, missing or irrelevant for solving a problem understands the problem structure and so is better
able to solve it. Such a student is likely to adopt a deep structure in categorizing physics problems. This latter result
corroborates with the findings of the expert-novice research paradigm.

This study investigated the effects of Guided Discovery vs. Didactic methods of instruction upon the acquisition of certain inquiry skills. At the same time, the effects of method on the attainment of factual-conceptual achievement was assessed. Hypotheses of no interaction of the methods variable with the learner variables—sex, measured intelligence, creativity, interest in science, general scholastic achievement, and science achievement—were also tested. The sample consisted of 140 8th-grade students. The duration of the experimental unit was six weeks. The subject matter was the same for each, “Early Man in America.” The results favored the Didactic group for the factual-conceptual achievement and the Guided Discovery for the acquisition of inquiry skills. However, in the latter there was an interaction of method with levels of measured intelligence and achievement. 相似文献

Large enrolment science courses play a significant role in educating undergraduate students. The discourse in these classes usually involves an instructor lecturing with little or no student participation, despite calls from current science education reform documents to elicit and utilize students’ ideas in teaching. In this study, we used the 5E instructional model to develop and implement four lessons in a large enrolment introductory biology course with multiple opportunities for teacher-student and student-student interaction. Data consisted of video and audio recordings of whole-class and small-group discussions that took place throughout the study. We then used a science classroom discourse framework developed by Mortimer and Scott (2003) to characterize the discursive interactions in each 5E lesson phase. Analysis of the data resulted in two assertions. First, the purpose, communicative approach, patterns of discourse, and teaching interventions were unique to each 5E lesson phase. Second, the type of lesson topic influenced the content of the discourse. We discuss how the findings help characterize the discourse of each phase in a 5E college science lesson and propose a model to understand internalization through discursive interaction using this reform-based approach. We conclude with implications for facilitating discourse in college science lessons and future research. This study provides support for using the discourse framework to characterize discursive interaction in college science courses. 相似文献

Scores from mathematics and science sections of pilot forms of the Michigan High School Proficiency Test (HSPT) were examined for evidence of an interaction between gender and response format (multiple choice or constructed response). When students of all ability levels were considered, the interaction was small in science and nonexistent in mathematics. When only the highest ability students were considered, male students scored higher on the multiple-choice section, whereas female students either scored higher on the constructed-response section or the degree to which the male students scored higher was less on the constructed-response section. Correlations between the formats were high and did not vary by gender. Standard errors of measurement were similar across gender. 相似文献

Few studies have examined the student learning effects of integrating science with mathematics and technology. We compared a school that integrated mathematics, science and technology in grade 9 to a school in the same district that taught the three courses separately. The distinguishing feature of the integrating school was the reorganization of instruction in the three subjects to prepare students for seven group projects (involving a total of 25 h) that required the application of knowledge and skill that were shared by the three subjects, as well as learning outcomes that were unique to each. The study detected benefits for students in the integrated setting in terms of their ability to apply shared learning outcomes, student motivation, ability to work together and attitudes to appraisal of group work. Female students in the integrated school had a better understanding of selected science learning outcomes. Attitudes toward mid‐term exams were higher in the control school. 相似文献

A questionnaire regarding attitudes toward science and scientific knowledge (Yager & Yager, 1985b) was administered to 143 intellectually gifted (IQ > 130) and intellectually average third-, seventh-, and eleventh-grade students. Measures of internal reliability on four attitude subscales and a content knowledge subscale are reported. Three-way ANOVAs comparing grade, sex, and ability revealed significant differences between average and gifted students in attitudes toward being a scientist, usefulness of science, and, as might be expected, in knowledge of science. Similarly, there were significant differences between grades on attitudes toward teachers and toward science classes, with the most favorable attitudes expressed in third grade, next most favorable in eleventh grade, and clearly more negative attitudes expressed by students in seventh grade. There also was a significant interaction between grade level and ability regarding attitudes toward science classes. In contrast to what might be expected from reported differences between males and females in attitudes toward science, gender as a separate variable did not have a significant main effect in any of the comparisons. 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

The purpose of this study was to determine the effects of computer-assisted instruction (CAI) versus a text mode of programmed instruction (PI), and the cognitive style of locus of control, on preservice elementary teachers' achievement of the integrated science process skills. Eighty-one preservice elementary teachers in six sections of a science methods class were classified as internally or externally controlled. The sections were randomly assigned to receive instruction in the integrated science process skills via a microcomputer or printed text. The study used a pretest-posttest control group design. Before assessing main and interaction effects, analysis of covariance was used to adjust posttest scores using the pretest scores. Statistical analysis revealed that main effects were not significant. Additionally, no interaction effects between treatments and loci of control were demonstrated. The results suggest that printed PI and tutorial CAI are equally effective modes of instruction for teaching internally and externally oriented preservice elementary teachers the integrated science process skills. 相似文献

The purpose of this study was to investigate the effects of representation sequences and spatial ability on students’ scientific understandings about the mechanism of breathing in human beings. 130 seventh graders were assigned to two groups with different sequential combinations of static and dynamic representations: SD group (i.e., viewing static representations and then dynamic ones), and DS group (i.e., viewing dynamic representations and then static ones). Among them, 16 students (8 from each group) with different levels of prior knowledge and spatial ability were interviewed. Data sources included a spatial ability test, pre- and post-tests of scientific understandings (involving factual, conceptual, and spatial knowledge), and semi-structured interviews. The statistical results indicated that the SD sequence helped students gain significantly more factual knowledge. The significant interaction effects further suggested that while the representation sequences had no effect on students with low spatial ability, high spatial ability students in the SD group outperformed than their counterparts in DS group on the items of the conceptual and spatial knowledge. Additionally, the analysis of interviews indicated that the representation sequences could affect the foci of students’ explanations and shape their perceptions about the representations. The results suggested interplays among representation sequences, spatial ability, and students’ understandings, and provided insight into the design and arrangement of multiple representations for science learning. 相似文献
