This study assessed the effectiveness of the systematic modeling teaching strategy on integrated science process skills and formal reasoning ability. Urban middle school students received a three-month process skill intervention treatment from teachers trained in either the use of systematic modeling or the learning-cycle model. A third, control group received traditional science instruction. The analysis of data revealed that (a) students receiving modeled instruction demonstrated a significant difference in their achievement of process skills when compared to either of the control groups. (b) Students taught by teachers who had received special process skill and strategy training demonstrated a significant difference in their process skill achievement when compared with the control group. (c) Students at different cognitive reasoning levels demonstrated significantly different process skill ability. 相似文献

Numerous persons have suggested that instruction should match the developmental level of the learner. Are “concrete operational” college students developmentally the same as “concrete operational” seventh grade students thus in need of identical instruction? Matched concrete operational seventh grade and college students were given identical classroom instruction in probabilistic and correlational reasoning. The college students performed significantly better on posttest measures which appeared to require greater processing of information while significant differences did not exist on less difficult items. Level of cognitive development, field independence, and fluid intelligence correlated moderately with posttest performance for the seventh grade students. Field independence and fluid intelligence correlated moderately with posttest performance for the college students but not pretest knowledge of specific biological concepts and cognitive level. It was concluded that college students are more responsive to instruction due either to (1) greater amount of experience or (2) greater information processing capacity. Implications for science teaching are discussed. 相似文献

This study examined the differential effectiveness of traditional and discovery methods of instruction for the teaching of science concepts, understandings about science, and scientific attitudes, to learners at the concrete and formal level of cognitive development. The dependent variables were achievement, understanding science, and scientific attitude; assessed through the use of the ACS Achievement Test (high school chemistry, Form 1979), the Test on Understanding Science (Form W), and the Test on Scientific Attitude, respectively. Mode of instruction and cognitive development were the independent variables. Subjects were 120 Form IV (11th grade) males enrolled in chemistry classes in Lusaka, Zambia. Sixty of these were concrete reasoners (mean age = 18.23) randomly selected from one of the two schools. The remaining 60 subjects were formal reasoners (mean age 18.06) randomly selected from a second boys' school. Each of these two groups was randomly split into two subgroups with 30 subjects. Traditional and discovery approaches were randomly assigned to the two subgroups of concrete reasoners and to the two subgroups of formal reasoners. Prior to instruction, the subjects were pretested using the ACS Achievement Test, the Test on Understanding Science, and the Test on Scientific Attitude. Subjects received instruction covering eight chemistry topics during approximately 10 weeks. Posttests followed using the same standard tests. Two-way analysis of covariance, with pretest scores serving as covariates was used and 0.05 level of significant was accepted. Tukey WSD technique was used as a follow-up test where applicable. It was found that (1) for the formal reasoners, the discovery group earned significantly higher understanding science scores than the traditional group. For the concrete reasoners mode of instruction did not make a difference; (2) overall, formal reasoners earned significantly higher achievement scores than concrete reasoners; (3) in general, subjects taught by the discovery approach earned significantly higher scientific attitude scores than those taught by the traditional approach. The traditional group outperformed the discovery group in achievement scores. It was concluded that the traditional approach might be an efficient instructional mode for the teaching of scientific facts and principles to high school students, while the discovery approach seemed to be more suitable for teaching scientific attitudes and for promoting understanding about science and scientists among formal operational learners. 相似文献

Summaries English The purpose of this study was twofold: (1) to investigate the cognitive development of llth‐grade science students in Jordan; and (2) to investigate the relationship between cognitive development of science students and their comprehension of concrete and formal physics concepts. The sample of this study consisted of 389 secondary science students (209 males and 180 females) of the school year 1979‐1980. Cognitive development of the students was measured by an Arabic version of the Longeot Test. Comprehension of physics concepts was assessed by an achievement test constructed by the researchers and validated by teachers of physics and the science supervisor in the Irbid district of Jordan. The study did not reveal any significant difference between males and females in cognitive development. Moreover, it revealed that only 17% of the students were formal thinkers, whereas 52% were concrete thinkers. The 2×3 ANOVA revealed that cognitive level was a highly significant factor in the comprehension of both concrete and formal concepts. It also revealed that while sex was not a significant factor in the comprehension of concrete concepts, it was a significant factor in the comprehension of formal concepts. The interaction between sex and cognitive level was not significant in the comprehension of both types of concepts. 相似文献

The reasoning patterns used by a sample of Western Australian secondary school students aged 13‐16 were investigated with regard to the following reasoning modes: proportional reasoning, controlling variables, probabilistic reasoning, correlational reasoning, and combinatorial reasoning. There was a wide range in students’ reasoning abilities at all year levels. Large percentages of students did not use formal operational reasoning patterns when they attempted to solve problems assessing their ability to use each of the five reasoning modes. Commonly used, but incorrect reasoning patterns were identified for each reasoning mode. The students’ ability to use formal reasoning patterns was found to be an important factor in determining student achievement in lower secondary science, in their selection of year 11 science subjects, and their achievement in these subjects. The results of the study indicate that it is important for teachers to be aware of the reasoning patterns of their students and the cognitive demands of course content, so that they can optimally match the content and their teaching strategies with the abilities of their students. Further research is needed to establish the nature of instruction which might best facilitate cognitive growth. 相似文献

The study investigated the differences related to formal reasoning abilities among students attending different sections of the upper cycle of secondary schools in Cyprus. The subjects of the study were twelfth‐grade students from 21 intact classes (227 boys and 242 girls). These classes were randomly selected among the 36 twelfth‐grade classes of four schools in a town of Cyprus. The sample of students represented the science section, the economic section and the “unified” section consisting of sections following common curricula in science and mathematics. Students’ performance on a standardized Test of Logical Thinking (TOLT) was used as a measure of their cognitive abilities related to control of variables, proportional, probabilistic, correlational and combinatorial reasoning. The students of the “unified” section had lower performance than the students of both the science and the economic section on all cognitive measures, and female students had lower performance than male students on cognitive measures related to control of variables and probabilistic reasoning. Multiple regression analysis between performance on TOLT and gender, section of study, and measures of school achievement showed that gender, section of study, achievement in mathematics, and grade point average, but not achievement in science and Greek language, contributed significantly to predicting performance on TOLT. Observed differences related to measures of school achievement either among the subjects of the three sections or between male and female students did not correspond to differences related to cognitive measures. Factor analysis of performance on the ten TOLT items (two items from each reasoning mode) produced a two‐factor solution. There were also significant differences in students’ performance between items related to the same or different reasoning mode. The results of the study cast doubt on the appropriateness of the existing curricula or their implementation and indicate that different theoretical perspectives should be considered when evaluating cognitive development. 相似文献

This study was designed to determine the influence of resequencing general science content on sixth grade students' science achievement, attitudes toward science, and interest in science. Resequencing content was accomplished for experimental group students through revising the order of textbook chapters in a general science course, in order to clarify content structure and establish interrelationships among major concepts. The subjects were 203 sixth grade learners randomly assigned to the two treatment groups of resequenced content and nonresequenced content. The findings revealed that students for whom content structure was clarified through resequencing general science chapters exhibited significantly higher science achievement, significantly more positive attitudes toward science, and significantly greater interest in science than students for whom general science content was not resequenced. 相似文献

AbstractThis study evaluated the Science and Literacy Instructional Model aimed at helping primarily Hispanic bilingual/English Learners (ELs) and economically disadvantaged fifth grade students with science achievement as measured by high-stakes standardized science achievement scores. The model combined purposeful planning, innovative academic vocabulary instruction, and a Lesson Design Lab. Difference-in proportions tests were used to determine if students at two school campuses showed positive achievement gains on a state science test. This study found statistically significant results with medium to large effect sizes at both campuses. Findings contribute to much needed research, practice, and policy in the area of effective models to assist both teachers and students in an era of high-stakes testing. 相似文献

Computer-assisted learning, including simulated experiments, has great potential to address the problem solving process which is a complex activity. It requires a highly structured approach in order to understand the use of simulations as an instructional device. This study is based on a computer simulation program, 'The Growth Curve of Microorganisms', which required tenth grade biology students to use problem solving skills whilst simultaneously manipulating three independent variables in one simulated experiment. The aims were to investigate the computer simulation's impact on students' academic achievement and on their mastery of science process skills in relation to their cognitive stages. The results indicate that the concrete and transition operational students in the experimental group achieved significantly higher academic achievement than their counterparts in the control group. The higher the cognitive operational stage, the higher students' achievement was, except in the control group where students in the concrete and transition operational stages did not differ. Girls achieved equally with the boys in the experimental group. Students' academic achievement may indicate the potential impact a computer simulation program can have, enabling students with low reasoning abilities to cope successfully with learning concepts and principles in science which require high cognitive skills. 相似文献

The study investigated the structure and development of formal thought among tenth-, eleventh-, and twelfth-grade students. The subjects of the study were the total numbers of students attending the science, the economic, and the other sections of two higher secondary schools. Students' performance on a standardized Test of Logical Thinking (TOLT) was used as a measure of their cognitive abilities related to control of variables, proportional, probabilistic, correlational, and combinatorial reasoning. Students attending the different sections of study had significantly different TOLT performance, older students exhibited significantly better TOLT performance than younger ones, and boys performed significantly better on TOLT than girls did. The “rate” of development was, however, different for different reasoning modes and differences in school achievement between boys and girls did not tap differences in TOLT performance. Regression analysis showed that section of study, gender, grade level, and measures of school achievement contributed significantly to the prediction of TOLT performance. Factor analysis of performance on the ten TOLT items (two items from each reasoning mode) produced a two- and three-factor solution for the sample of boys and the sample of girls, respectively. The results indicate that different theoretical perspectives should be considered when evaluating cognitive development and that learning environments conducive to cognitive growth need to be designed and implemented. 相似文献

This study investigated students' achievement regarding photosynthesis and respiration in plants in relation to reasoning ability, prior knowledge and gender. A total of 117 eighth‐grade students participated in the study. Test of logical thinking and the two‐tier multiple choice tests were administered to determine students' reasoning ability and achievement, respectively. An analysis of covariance (ANCOVA) was conducted to assess the effect of reasoning ability on students' achievement. The independent variable was the reasoning ability (low, medium, high), the dependent variable was the scores on the two‐tier test. Students' grades in science in previous year were used as a covariate. Analysis revealed a statistically significant mean difference between students at high and low formal levels with respect to achievement. Stepwise multiple regression analysis revealed that reasoning ability, prior knowledge and gender were significant predictors of students' achievement in photosynthesis and respiration in plants, explaining 42% of the variance. 相似文献

Evidence from the research literature suggests that a variety of cognitive factors is responsible for chemistry achievement. This investigation examined the role of four cognitive factors, namely, formal reasoning ability, prior knowledge, field dependence/ independence, and memory capacity on achievement in chemistry as measured by tests of laboratory application, chemical calculations and content knowledge. The sample comprised grade 11 students from eleven high schools who were following the same chemistry syllabus. The results indicated that prior knowledge and formal reasoning ability were each statistically significantly related to variation in chemistry achievement. Field dependence/independence and memory capacity played no significant role in chemistry achievement. 相似文献

The present study compared the relative effects of hands-on and teacher demonstration laboratory methods on declarative knowledge (factual and conceptual) and procedural knowledge (problem-solving) achievement. Of particular interest were (a) whether these relationships vary as a function of reasoning ability and (b) whether prior knowledge and reasoning ability predict student achievement. Ninth-grade physical science students were randomly assigned to classes taught by either a hands-on or a teacher demonstration laboratory method. Students' reasoning ability and prior knowledge of science were assessed prior to the instruction. The two instructional methods resulted in equal declarative knowledge achievement. However, students in the hands-on laboratory class performed significantly better on the procedural knowledge test than did students in the teacher demonstration class. These results were unrelated to reasoning ability. Prior knowledge significantly predicted performance on the declarative knowledge test. Both reasoning ability and prior knowledge significantly predicted performance on the procedural knowledge test, with reasoning ability being the stronger predictor. 相似文献

The mechanism linking instruction in scientific topics and instruction in logical reasoning strategies is not well understood. This study assesses the role of science topic instruction combined with logical reasoning strategy instruction in teaching adolescent students about blood pressure problems. Logical reasoning instruction for this study emphasizes the controlling-variables strategy. Science topic instruction emphasizes variables affecting blood pressure. Subjects receiving logical reasoning instruction link their knowledge of blood pressure variables to their knowledge of controlling variables more effectively than those receiving science topic instruction alone—their specific responses show how they attempt to integrate their understanding. 相似文献

Although the development of reasoning is recognized as an important goal of science instruction, its nature remains somewhat of a mystery. This article discusses two key questions: Does formal thought constitute a structured whole? And what role does propositional logic play in advanced reasoning? Aspects of a model of advanced reasoning are presented in which hypothesis generation and testing are viewed as central processes in intellectual development. It is argued that a number of important advanced reasoning schemata are linked by these processes and should be made a part of science instruction designed to improve students' reasoning abilities. Concerning students' development and use of formal reasoning, Linn (1982) calls for research into practical issues such as the roles of task-specific knowledge and individual differences in performance, roles not emphasized by Piaget in his theory and research. From a science teacher's point of view, this is good advice. Accordingly, this article will expand upon some of the issues raised by Linn in a discussion of the nature of advanced reasoning which attempts to reconcile the apparent contradiction between students' differential use of advanced reasoning schemata in varying contexts with the notion of a general stage of formal thought. Two key questions will be discussed: Does formal thought constitute a structured whole? And what role does propositional logic play in advanced reasoning? The underlying assumption of the present discussion is that, among other things, science instruction should concern itself with the improvement of students' reasoning abilities (cf. Arons, 1976; Arons & Karplus, 1976; Bady, 1979; Bauman, 1976; Educational Policies Commission, 1966; Herron, 1978; Karplus, 1979; Kohlberg & Mayer, 1972; Moshman & Thompson, 1981; Lawson, 1979; Levine & linn, 1977; Pallrand, 1977; Renner & Lawson, 1973; Sayre & Ball, 1975; Schneider & Renner, 1980; Wollman, 1978). The questions are of interest because to date they lack clear answers, yet clear answers are necessary if we hope to design effective instruction in reasoning. 相似文献

Explaining natural phenomena is an important goal in science teaching. A logical analysis reveals that causal explanations exhibit formal operational structures in that they consist of implication statements chained together through transitive reasoning. It was hypothesized in the present study that individuals who do not reason formally will have difficulty in learning explanations presented in instruction. To test this hypothesis, the effect of levels of operational thought on the explanations which ninth-grade (n = 26) and college (n = 40) physical science students reconstructed after instruction was investigated. Subjects in the study were classified through Piagetian tests as concrete or formal operational. Both concrete and formal subjects were successful in recalling explanations requiring the chaining of two implication statements. Formal operational subjects performed significantly better than concrete operational subjects in three of the four tests of the reconstruction of complex explanations requiring the chaining of six implication statements. In teaching complex causal explanations to students at the concrete operational level, it is suggested that teachers be prepared to furnish some external structuring which the students can rely on in logically relating the various propositions of the explanation to one another. 相似文献

The study investigated the benefits of a matching model of instruction for students enrolled in ninth grade physical science classes in one high school in a small, urban school district. Based on social learning theory, three independent variables were identified for purposes of matching: need level, cognitive style, and locus of control; attitude and achievement outcomes served as the dependent variables. Results of separate analyses of covariance revealed that attitude toward science in general improved with matching, but achievement, attitude toward physical science, attitude toward instruction, and attitude toward the teacher did not improve. Recommendations for subsequent “matching” experiments are discussed in light of the findings in this investigation. 相似文献

Abstract. Thirty‐four matched pairs of sixth‐ and seventh‐grade students were selected from 358 participants in a comparison of an explicit concrete‐to‐representational‐to‐abstract (CRA) sequence of instruction with traditional instruction for teaching algebraic transformation equations. Each pair of students had been previously labeled with a specific learning disability or as at risk for difficulties in algebra. Students were matched according to achievement score, age, pretest score, and class performance. The same math teacher taught both members of each matched pair, but in different classes. All students were taught in inclusive settings under the instruction of a middle school mathematics teacher. Results indicated that students who learned how to solve algebra transformation equations through CRA outperformed peers receiving traditional instruction on both postinstruction and follow‐up tests. Additionally, error pattern analysis indicated that students who used the CRA sequence of instruction performed fewer procedural errors when solving for variables. 相似文献

A one-year lag was found between the effect of an intervention intended to promote formal operational thinking in students initially 11 or 12 years of age and the appearance of substantial science achievement in the experimental groups. A one-year lag was also reported on cognitive development: Whereas at the end of the two-year intervention the experimental groups were up to 0.9σ ahead of the control groups, one year later the differential on Piagetian measures had disappeared, but the experimentals now showed better science achievement of even greater magnitude. Although the control groups showed normal distribution both on science achievement and cognitive development, the experimental groups showed bi- or trimodal distribution. Between one-half and one-quarter of the students involved in the experiment in different groups showed effects of the order of 2σ both on cognitive development and science achievement; some students appeared unaffected (compared with the controls), and others demonstrated modest effects on science achievement. An age/gender interaction is reported: the most substantial effects were found in boys initially aged 12+ and girls initially 11+. The only group to show no effects was boys initially aged 11+. It is suggested that the intervention methods may have favored the abstract analytical learning style as described by Cohen 1986. 相似文献

We conducted a laboratory‐based randomized control study to examine the effectiveness of inquiry‐based instruction. We also disaggregated the data by student demographic variables to examine if inquiry can provide equitable opportunities to learn. Fifty‐eight students aged 14–16 years old were randomly assigned to one of two groups. Both groups of students were taught toward the same learning goals by the same teacher, with one group being taught from inquiry‐based materials organized around the BSCS 5E Instructional Model, and the other from materials organized around commonplace teaching strategies as defined by national teacher survey data. Students in the inquiry‐based group reached significantly higher levels of achievement than students experiencing commonplace instruction. This effect was consistent across a range of learning goals (knowledge, reasoning, and argumentation) and time frames (immediately following the instruction and 4 weeks later). The commonplace science instruction resulted in a detectable achievement gap by race, whereas the inquiry‐based materials instruction did not. We discuss the implications of these findings for the body of evidence on the effectiveness of teaching science as inquiry; the role of instructional models and curriculum materials in science teaching; addressing achievement gaps; and the competing demands of reform and accountability. © 2009 Wiley Periodicals, Inc.
