This study explored Morine and Morine's (Discovery: A challenge to teachers. Englewood Cliffs, NJ: Prentice-Hall, 1973) assumptions regarding age and cognitive development of learners successfully utilizing two types of inquiry, specifically structured inductive and semi-deductive. Two groups of elementary school students from grades one, three and five were individually assessed on six conservation tasks and a multiplicative classification task. The two groups were instructed on two different science topics utilizing different inquiry strategies. Achievement data from topic specific tests were analyzed by an ANOVA technique. The results indicated that age made a significant difference on achievement for both inquiry strategies. The significant contributions were due to the differences between grade one and grades three and five. The differences between grade three and grade five were not significant. The effect of cognitive development was more noticeable in the less structured semi-deductive strategy in which four conservation tasks and the multiplicative classification tasks were significant.  相似文献

The traditional approach to teaching science problem solving is having the students work individually on a large number of problems. This approach has long been overtaken by research suggesting and testing other methods, which are expected to be more effective. To get an overview of the characteristics of good and innovative problem‐solving teaching strategies, we performed an analysis of a number of articles published between 1985 and 1995 in high‐standard international journals, describing experimental research into the effectiveness of a wide variety of teaching strategies for science problem solving. To characterize the teaching strategies found, we used a model of the capacities needed for effective science problem solving, composed of a knowledge base and a skills base. The relations between the cognitive capacities required by the experimental or control treatments and those of the model were specified and used as independent variables. Other independent variables were learning conditions such as feedback and group work. As a dependent variable we used standardized learning effects. We identified 22 articles describing 40 experiments that met the standards we deemed necessary for a meta‐analysis. These experiments were analyzed both with quantitative (correlational) methods and with a systematic qualitative method. A few of the independent variables were found to characterize effective strategies for teaching science problem solving. Effective treatments all gave attention to the structure and function (the schemata) of the knowledge base, whereas attention to knowledge of strategy and the practice of problem solving turned out to have little effect. As for learning conditions, both providing the learners with guidelines and criteria they can use in judging their own problem‐solving process and products, and providing immediate feedback to them were found to be important prerequisites for the acquisition of problem‐solving skills. Group work did not lead to positive effects unless combined with other variables, such as guidelines and feedback. © 2001 John Wiley & Sons, Inc. J Res Sci Teach 38: 442–468, 2001  相似文献

Seventy-nine subjects who had less than 1, 2, to 3, and more than 3 years of teaching experience were given either a favorable, neutral, or unfavorable fictitious psychological report to read, describing a kindergarten child. Subjects then watched a 5-year-old child in a videotaped testing session. Expectancies toward the child were evaluated using report card grades the subjects expected the child to receive at the end of first grade. A multivariate analysis of variance with five subject area grades as the dependent variables revealed significant multivariate main effects for experience and psychological report. Significant univariate interactions in science and social studies, and social and emotional development suggested that teachers with more than 3 years of experience may have reduced susceptibility to biasing influences in psychological reports.  相似文献

The study examined into the relationship between gender and students' misconceptions in science. Two different groups were treated with two different teaching strategies, namely, teaching strategy 1, which is basically didactic in nature, and teaching strategy 11, which incorporates students' misconceptions and applies the Generative Learning Model. Two groups of secondary three students (N=26,27; randomly sampled), underwent 6 weeks of instruction, with the respective strategies mentioned above. Each group consisted of male and female students, the numbers of which resulted from the grouping based on their academic achievements. A constructed and validated diagnostic instrument was used as a means to measure the effectiveness of these two teaching strategies. The findings showed that gender differences did not relate well to students' misconceptions in science. The implications of this finding are discussed.  相似文献

The two goals of the study were to examine factors affecting parents' teaching strategies with their children and to identify the effectiveness of different teaching strategies for engaging children in tasks. It was hypothesized that teaching strategies would vary as a function of parent status (mother/father), children's communicative status (nonhandicapped-NCH/handicapped-CH) and different tasks (origami/book reading). Each of the 120 families included a target child (M = 4.5 years old), a mother, and a father; 60 families had a CH child and 60 matched families had an NCH child. Each parent engaged in book-reading and origami tasks with their target child. Parents' teaching strategies were recorded and categorized according to levels of cognitive demand. In addition, children's level of task engagement was rated. Results indicated that parents varied their teaching strategies according to both task and children's communicative status. Generally, they were more demanding and less directive of the more competent, NCH, children than of the CH children. Further, parents used different strategies with their NCH and CH children in both tasks to keep them engaged. Results are discussed in terms of Vygotsky's theory of the zone of proximal development.  相似文献

There are few research studies on the effects of teaching comprehension strategies to young children in the primary grades. Using a Dominant–Less Dominant Mixed Model design employing both qualitative and quantitative data collection, we evaluated two approaches for teaching comprehension strategies to 7- and 8-year-old children in four second-grade classrooms using science information texts. The first approach focused upon explicitly teaching a series of single comprehension strategies, one-at-a-time (SSI). The second approach focused on teaching a “set” or “family” of transacted comprehension strategies within a collaborative, interactive and engaging routine (TSI). Results showed no difference between teaching young children a “set” of comprehension strategies and teaching comprehension strategies explicitly, one-at-a-time on their reading comprehension performance as measured by a standardized test of reading comprehension, recall of main ideas from reading two 200 word passages from information texts, a reading motivation survey and a strategy use survey. Results showed significant differences between students taught a set of comprehension strategies on measures of elaborated knowledge acquisition from reading science books (detail idea units recalled), retention of science content knowledge, and significantly improved criterion or curriculum-based reading comprehension test scores. These benefits favoring TSI over SSI are important because the learning curve is relatively steep for teachers to develop the ability to teach and for young children to develop the ability to coordinate a “set” of transacted comprehension strategies.  相似文献

A random sample of 400 K-12 science educators who were members of the National Science Teachers Association were surveyed regarding their attitude toward and practice of career education in their science teaching. These science teachers rejected a narrowly vocational view, favoring instead a conception of career education which included self-perception, values analysis, and vocational skills objectives. The science educators affirmed the importance of career education for a student's education, asserted career education ought to be taught in their existing science courses, and expressed a willingness to do so. Fewer than one-third of the science teachers, however, reported incorporating career education at least on a weekly basis in their science lessons. The major impediment to including more career education in science teaching was seen to be their lack of knowledge of methods and materials relevant to science career education, rather than objections from students, parents, or administrators; their unwillingness; or their evaluation of career education as unimportant. Thus, in order to improve this aspect of science teaching, science teachers need more concrete information about science career education applications.  相似文献

Thirty gifted and 30 average readers were selected from a population of 300 eighth, tenth, and twelfth grade students in small towns or rural areas in Kansas. Students were classified as field independent or field dependent. It was found that gifted and average readers used the same reading strategies but there were significant differences in how frequently some strategies were used. There were also significant differences in how frequently some strategies were used by field independent and field dependent readers. Gifted readers scored significantly higher than average readers on the Hidden Figures Test. No significant differences in the frequency of reading strategy use were found between field independent gifted readers and field dependent gifted readers or between field independent and field dependent average readers.  相似文献

Two professional preparation paths lead to teaching positions in the lower primary grades; their different histories and emphasis result in potentially conflicting paradigms. We examined the viewpoints of 119 pre-service teachers who were either at the beginning or near the end of their programs in early childhood (ECED) or elementary education (ELED). They completed a survey of their beliefs about primary classroom practices. ECED students, compared to ELED students, favored practices more consistent with the constructivist nature of National Association for the Education of Young Children (NAEYC) guidelines in several areas, including teaching strategies, expectations of the children, assessment strategies, and teacher- and child-directed activities. One significant difference was found between beginning students and student teachers, with student teachers favoring more frequent use of less developmentally appropriate behavior management strategies.  相似文献

Summary This study is of interest for a number of reasons. The first relates to the measures used to assess teacher behaviour and the comprehensive procedures followed to establish reliability. The second is associated with the large sample size which represents nearly the entire population. The third is concerned with the overall lack of relationship between teacher behaviours and growth in science achievement that is apparent from this secondary analysis. Although the first two of these features are relatively uncommon to research studies in the field of teacher effectiveness using observers, the last is far from unique. The lack of relationships between observed low inference teacher behaviour and student gain in achievement on cognitive outcomes has been noted frequently in reviews of the literature (one of the latest being, Rosenshine, 1978). It is, of course, possible to discuss the overall lack of relationship between teacher and student behaviour and science achievement gain as a consequence of unreliabilities of measurement of the independent and dependent variables. It is possible to take a more optimistic view and observe that the data reported here were collected in Canberra in 1969. The prevalence of streaming would have resulted in certain teaching behaviour being more highly correlated with both pre-test and post-test scores than would be found if streaming had not been present. In addition, the homogeneity of teaching behaviour imposed by an inspectorial system would have reduced the variance in the independent variables. Hopefully, a replication today would be more likely to identify effective teaching behaviour. However, one thing appears evident. Any investigation that does not exceed the one reported above in establishing the reliability and stability of its measures, or in the extent and scope of the study, is not likely to produce findings of greater strength than have been presented in this paper.  相似文献

The efforts of 69 elementary school teachers to instruct children in cognitive processing activities were observed. Although the teaching of such activities was relatively infrequent, it varied by grade (occurring more often in grades 2-3 than in higher or lower grades) and by the content of instruction. Teachers of grade 4 and above more often provided rationales for the use of cognitive strategies than did teachers of younger children. In a second study, children of three achievement levels were selected from classrooms in which teachers varied in their use of suggestions regarding cognitive processes. Subsequent to training in the use of a memory strategy, children's performance on a maintenance trial was evaluated: Among average and low achievers, those whose teachers were relatively high in strategy suggestions showed better maintenance and more deliberate use of the trained strategy than did children whose teachers rarely made strategy suggestions. The role of school experience in the development of children's memory skills is discussed.  相似文献

The present study examined the efficacy of two different approaches to teaching designed to facilitate children's learning about science concepts and vocabulary related to objects’ floating and sinking and scientific problem-solving skills: responsive teaching (RT) and the combination of responsive teaching and explicit instruction (RT + EI). Participants included 104 children (51 boys) aged four to five years. Small groups of children were randomly assigned to one of the two intervention groups (RT, RT + EI) or to a control group. Responsive teaching (RT) reflects a common approach to teaching young children, and the combination approach (RT + EI) includes explicit instruction as well as responsive teaching. The two planned interventions were implemented with preschool children and provided evidence that (1) young children learned science concepts and vocabulary better when either responsive teaching or the combination of responsive teaching and explicit instruction was used; (2) children in the combined intervention group learned more science concepts and vocabulary and more content-specific scientific problem-solving skills than children in either the responsive teaching or control groups. Limitations, future directions, and implications for practice are also discussed.  相似文献

This study examines the effect of an in-service education program emphasizing problem solving on teacher attitudes toward teaching science and on teaching behaviors. Twenty-two middle school science teachers participated in the program and another 22 served as the control group. The two groups were similar in terms of gender, teaching status, educational background, and professional activity during the treatment period. Before and after the eight-month project, subjects completed attitude surveys and recorded videotapes of themselves teaching science lessons. No difference was noted between the groups on the attitude measure. The videotapes were analyzed using a coding scheme developed for use in this study. A multivariate analysis of variance performed on the observational data showed a significant difference between the groups on the postworkshop measure. The experimental-group teachers shifted to more student-centered classrooms, with less lecture and procedural talk. This study provides evidence that an extended in-service education program can affect the teaching behaviors of science teachers in the middle grades.  相似文献

A random sample of middle school teachers (grades 6–9) from across the United States was surveyed about their use of writing to support students’ learning. The selection process was stratified so there were an equal number of English language arts, social studies, and science teachers. More than one-half of the teachers reported applying 15 or more writing to learn strategies at least once a month or more often. The most commonly used writing to learn strategies were writing short answers to questions, note taking for reading, note taking while listening, and completing worksheets. While teachers reported using a variety of writing to learn strategies, most of them indicated they received minimal or no formal preparation in college on how to use writing to learn strategies to support student learning, less than one-half of teachers directly taught students how to use the writing to learn strategies commonly assigned, and the most commonly used writing to learn strategies did not require students to think deeply about the material they were learning. We further found that teachers’ reported use of writing to learn strategies was related to their preparedness and the composition of their classroom in terms of above and below average writers, English Language Learners, and students with disabilities.  相似文献

The purpose of this study was to describe the influence of constructivist classroom contextual factors in a life science laboratory and a traditional science classroom on elementary students’ motivation and learning strategy use. The Constructivist Teaching Inventory was used to examine classroom contextual factors. The Motivated Strategies for Learning Questionnaire was used to examine student motivation and learning strategies. A Wilcoxon nonparametric test determined that constructivist teaching practices were found to occur more often in the life laboratory than in the regular classroom. Although constructivist teaching practices increased at each observation time in both the regular classroom and in the life laboratory, a Friedman test determined that they were not statistically significant increases. Paired sample t tests determined that student motivation and learning strategies were higher in the life laboratory than in the regular classroom overall as well as at each survey time except for learning strategies at Post 1. A 2 × 4 between 3 within repeated measure ANOVA determined that student MSLQ motivation and learning strategy scores in the regular classroom varied statistically significantly by teacher. Student MSLQ motivation and learning strategy scores in the life laboratory varied statistically significantly by teacher. To triangulate data, individual interviews of students were conducted at the end of the semester and revealed students regard the life laboratory as an asset to their science study; however, students do appreciate and value working in the learning environment that the regular classroom provides.  相似文献

Evaluating major post-secondary education improvement projects involves multiple perspectives, including students’ perceptions of their experiences. In the final year of a seven-year department-wide science education initiative, we asked students in 48 courses to rate the extent to which each of 39 teaching or learning strategies helped them learn in the course. Results were related to the type of improvement model used to enhance courses, class size and course year level. Overall, students perceived unimproved courses as least helpful. Small courses that were improved with support from science education specialists were perceived overall as more helpful than similar courses improved by expert teaching-focused faculty without support, while the opposite was found for medium courses. Overall perceptions about large courses were similar to perceptions of medium courses. Perceived helpfulness of individual strategies was more nuanced and context dependent, and there was no consistent preference for either traditional or newer evidence-based instructional practices. Feedback and homework strategies were most helpful in smaller courses and independently improved courses. Results indicate that students are perceptive to benefits that arise when improvements are made either by expert educators or by research-focused faculty who received dedicated support from science education specialists.  相似文献

SUMMARY This article reports on an unexpected finding from a larger study. The research was focused on examining the effectiveness of a coalescent curriculum structure of the skill development units in a one-year intensive teacher professional preparation program. Effectiveness was determined by ascertaining the transfer of complex models of teaching into the regular teaching repertoire by graduates. The entire population of two consecutive cohorts were interviewed by telephone, using a semi-structured schedule. The findings presented in this article relate to a sub-group of the total sample who were found to have adopted a more complex approach of integrating two or more models, either within one lesson, or over a series of lessons. The teachers who successfully and regularly utilised two or more complex strategies, appeared to exhibit high levels of self-efficacy, sound self-reflection techniques, and reported feeling more in control and less stressed than their less adventurous colleagues.  相似文献
