In a recent article that appeared in this journal, Hofstein and Mandler (1985) reported a study which employed the Lawson's (1978) classroom test of formal reasoning to determine, among other things, the relationship between achievement in science and mathematics in a sample of Israeli students. Based on their findings, the authors raised objections to the classroom utility of the test for diagnosing students' developmental levels. The present author, however, argued that the case has not been properly established in view of one major methodological problem which seemed to characterize the study. Accordingly, the plea to abandon Lawson's test of formal reasoning was questioned.  相似文献

Lawson (1992) posited the multiple hypothesis theory to explain the essence of scientific reasoning. According to this theory, the essence of scientific reasoning is “the ability to initiate reasoning with more than one antecedent condition.” The present study tests the assumptions of this theory with high school students in general experience areas and in chemistry. The findings are generally in support of the theory's assumptions. This article also contains a theoretical discussion which points out how the theory needs to be extended before it can justifiably “constitute the core of a viable alternative theory of reasoning.” © 1997 John Wiley & Sons, Inc.

A central purpose of education is to improve students' reasoning abilities. The present review examines research in developmental psychology and science education that has attempted to assess the validity of Piaget's theory of formal thought and its relation to educational practice. Should a central objective of schools be to help students become formal thinkers? To answer this question research has focused on the following subordinate questions: (1) What role does biological maturation play in the development of formal reasoning? (2) Are Piaget's formal tasks reliable and valid? (3) Does formal reasoning constitute a unified and general mode of intellectual functioning? (4) How does the presence or absence of formal reasoning affect school achievement? (5) Can formal reasoning be taught? (6) What is the structural or functional nature of advanced reasoning? The general conclusion drawn is that although Piaget's work and that which has sprung from it leaves a number of unresolved theoretical and methodological problems, it provides an important background from which to make substantial progress toward a most significant educational objective. All our dignity lies in thought. By thought we must elevate ourselves, not by space and time which we can not fill. Let us endeavor then to think well; therein lies the principle of morality.

The purpose of this research was to examine how science content knowledge, moral reasoning ability, attitudes, and past experiences mediate the formation of moral judgments on environmental dilemmas. The study was conducted in two phases using environmental science majors and nonscience majors of college age. Phase One determined if environmental science majors exhibited higher levels of moral reasoning on nontechnical environmental social issues than on general social issues and examined the extent to which possible mediating factors accounted for differences in moral reasoning. Phase Two was qualitative in nature, the purpose of which was to observe and identify trends in conversations between subjects as to how certain mediating factors are revealed as people form moral judgments. The framework on which this study was constructed incorporates a progressive educational position; a position that views science education as being interdisciplinary, and a social means to a social end.  相似文献

ABSTRACT

Concerns have been expressed that the engagement shown by committed individuals is not fully utilized by their organizations while there is insufficient knowledge of which conditions facilitate teaching collaboration and lead to improvements in university education. Portfolios of 43 life science academics applying to enter to the University of Helsinki Teachers’ Academy were analyzed through content analysis. Five categories of interactive or collaborative practices emerged from the data: (1) Interacting with peers for personal development, (2) Sharing good teaching practices, (3) Teaching together, (4) Producing educational artefacts, (5) Developing education systematically. The practices occurred in both formal and informal settings, and both settings were present in all categories. In contrast with the formal practices, the informal practices were described in an enthusiastic way. The engagement shown by the scholarly teachers was mostly realized in informal settings. There is probably unrealized potential in the scholarly teachers’ teaching-related practices through which they could contribute to the development of teaching in academia. Formal communities related to teaching should be developed to promote deeper collaboration and to foster the participants’ feeling of personal commitment and ownership.  相似文献

The gap between enrollments in higher education computing programs and the high-tech industry’s demands is widely reported, and is especially prominent for women. Increasing the availability of computer science education in high school is one of the strategies suggested in order to address this gap. We look at the connection between exposure to computer science in high school and pursuing computing in higher education. We also examine the gender gap, in the context of high school computer science education. We show that in Israel, students who took the high-level computer science matriculation exam were more likely to pursue computing in higher education. Regarding the issue of gender, we will show that, in general, in Israel the difference between males and females who take computer science in high school is relatively small, and a larger, though still not very large difference exists only for the highest exam level. In addition, exposing females to high-level computer science in high school has more relative impact on pursuing higher education in computing.  相似文献

Several recent studies suggest concrete learners make greater gains in student achievement and in cognitive development when receiving concrete instruction than when receiving formal instruction. This study examined the effect of concrete and formal instruction upon reasoning and science achievement of sixth grade students. Four intact classes of sixth grade students were randomly selected into two treatment groups; concrete and formal. The treatments were patterned after the operational definitions published by Schneider and Renner (1980). Pretest and posttest measures were taken on the two dependent variables; reasoning, measured with Lawson's Classroom Test of Formal Reasoning, and science achievement, measured with seven teacher made tests covering the following units in a sixth grade general science curriculum: Chemistry, Physics, Earth Science, Cells, Plants, Animals, and Ecology. Analysis of covariance indicated significantly higher levels (better than 0.05 and in some cases 0.01) of performance in science achievement and cognitive development favoring the concrete instruction group and a significant gender effect favoring males.  相似文献

An instrument was developed to assess the logical reasoning capacity of adolescents in the content area of environmental science. Characterized as a group test, the instrument consisted of five concrete experiences related to environmental concepts, to which pencil-and-paper responses were made. The instrument was validated through (1) logical analysis of items from the standpoint of Piagetian theory, (2) correlation with clinical interviews and group test results in physical science, and (3) factor analysis. The results indicated an acceptable level of validity for the instrument in each category. Concurrently, the results of the study indicated that the reasoning level of the subjects was well below the theoretical levels predicted for them by theory. The results also suggested that reasoning ability in environmental science was lower than in areas associated with the physical concepts usually tested. The data suggested the presence of a horizontal decalage, or time lag, between the development of logical reasoning skills in areas of familiarity, such as physical science, and areas of content less familiar to the subject or those in which logical structures may be less frequently used in the development of evaluation instruments.  相似文献

In this article I critically examine the historical context of science education in a natural history museum and its relevance to using museum resources to teach science today. I begin with a discussion of the historical display of race and its relevance to my practice of using the Museum’s resources to teach science. I continue with a critical review of the history of the education department in a natural history museum to demonstrate the historical constitution of current practices of the education department. Using sociocultural constructs around identity formation and transformation, I move to the present with a case study of a teacher who transforms the structure of science education in her classroom and school as a result of her identity transformation and association with a museum-based professional education program.

The aim of this study was to identify if wireless keypads could facilitate interprofessional interaction among undergraduate paramedic, nursing, occupational therapy, physiotherapy, health science, social work and midwifery students. Secondary research aims included the examination of students' perceptions of interprofessional education and how students perceived using wireless keypads in large lecture classes and smaller tutorials. The study used a mixed methodology approach via self‐reporting questionnaires and focus groups that included (n = 210) students in week 1 and (n = 151) students in week 13 of an undergraduate unit. Overall, students were satisfied with the use of wireless keypads in their interprofessional undergraduate unit of study. While modest findings supported the use of wireless keypads in improving student interaction, other findings were statistically significant in understanding the roles of other health professions and why collaboration in health‐care environments was important for professional growth. The following themes emerged from the qualitative data: engagement, satisfaction, use of educational technology, interprofessional education and learning environment. Integration of wireless keypads has assisted undergraduate students to better appreciate and understand other health‐care disciplines within an interprofessional education setting. Students reported that they appreciated the alternative teaching and learning approach that wireless keypads offered, thus improving engagement and interactivity, and providing a broader understanding of other allied health‐care professions.  相似文献

We present a multiple-choice test, the Montana State University Formal Reasoning Test (FORT), to assess college students' scientific reasoning ability. The test defines scientific reasoning to be equivalent to formal operational reasoning. It contains 20 questions divided evenly among five types of problems: control of variables, hypothesis testing, correlational reasoning, proportional reasoning, and probability. The test development process included the drafting and psychometric analysis of 23 instruments related to formal operational reasoning. These instruments were administered to almost 10,000 students enrolled in introductory science courses at American universities. Questions with high discrimination were identified and assembled into an instrument that was intended to measure the reasoning ability of students across the entire spectrum of abilities in college science courses. We present four types of validity evidence for the FORT. (a) The test has a one-dimensional psychometric structure consistent with its design. (b) Test scores in an introductory biology course had an empirical reliability of 0.82. (c) Student interviews confirmed responses to the FORT were accurate indications of student thinking. (d) A regression analysis of student learning in an introductory biology course showed that scores on the FORT predicted how well students learned one of the most challenging concepts in biology, natural selection.  相似文献

This paper provides a critical analysis of some of the issues raised in Simonneaux and Simonneaux’s analysis of socioscientific reasoning among a group of university level students negotiating three socioscientific issues. I first discuss the labels used to reference approaches in science education that prioritize socially relevant issues and the science related to these issues. I draw distinctions between approaches labeled science-technology-society (STS), the socioscientific issues framework, and les questions socialement vives (socially acute questions), which Simonneaux and Simonneaux introduce. Next, I discuss ways in which Simonneaux and Simonneaux’s use socioscientific reasoning as an analytic construct varies with respect to its initial conceptualization. The primary distinctions include linguistic inconsistencies and the conceptual differences these language choices confer, expansion of the construct to subsume a broader range of practices, and issues related to unit of analysis (i.e., applying socioscientific reasoning as an analytic resource for assessing individual practice vs. group patterns). Finally, the issue of transfer of socioscientific reasoning is addressed. When considering the extent to which and how students leverage experiences and practice relative to the exploration of one socioscientific issue to inform their negotiation of another, I suggest that researchers and practitioners consider the distinction between the content of arguments advanced and underlying reasoning patterns. The tension between embedding science in meaningful, specific contexts and promoting forms of scientific literacy applicable to diverse, socially-relevant issues emerges as an important point of emphasis for educators interested in the socioscientific issues (or socially acute questions) movement.

Practical reasoning is a fundamental competence required for everyday decision-making as well as for the production of scientific knowledge. However, very little attention is given to developing this competence in school science classrooms or in educational research programs. In this paper we explain the tradition of practical reasoning and its relevance to science and science education. We then suggest ways in which practical reasoning may be developed in students such that they are enabled to better understand how scientific knowledge is produced and how they may be better able to contribute to improving scientific practices.  相似文献

Piaget's theory has profoundly influenced science education research. Following Piaget, researchers have focused on content-free strategies, developmentally based mechanisms, and structural models of each stage of reasoning. In practice, factors besides those considered in Piaget's theory influence whether or not a theoretically available strategy is used. Piaget's focus has minimized the research attention placed on what could be called “practical” factors in reasoning. Practical factors are factors that influence application of a theoretically available strategy, for example, previous experience with the task content, familiarity with task instructions, or personality style of the student. Piagetian theory has minimized the importance of practical factors and discouraged investigation of (1) the role of factual knowledge in reasoning, (2) the diagnosis of specific, task-based errors in reasoning, (3) the influence of individual aptitudes on reasoning (e.g., field dependence-independence), and (4) the effect of educational interventions designed to change reasoning. This article calls for new emphasis on practical factors in reasoning and suggests why research on practical factors in reasoning will enhance our understanding of how scientific reasoning is acquired and of how science education programs can foster it.  相似文献

To test the hypothesis that cultural diversity contributes to the development of formal reasoning, samples of adolescents from three predominately white middle-class communities located in areas that varied in the extent to which they offered cultural diversity (i.e., rural, suburan homogeneous, suburban heterogeneous) were administered a test of formal reasoning and a test of analytical intelligence. Results showed significant differences in formal reasoning in favor of the suburban heterogeneous sample on complex reasoning items. The suburban groups showed equal performance (but superior to the rural Ss) on the test of analytical intelligence. On the less complex reasoning items and on one item embedded in a rural farming context, the rural Ss showed relatively better performance. Implications for using science instruction to promote formal reasoning are discussed.  相似文献
