Both chemistry teachers and nonmajor students appear to agree that freshman chemistry may well be the most problematic traditional science discipline taught in the first year of college—as far as students' misunderstandings, learning difficulties, and misconceptions are concerned. The above is probably due to the many abstract, nonintuitive concepts, which are not directly interrelated. Consequently, in such cases, the powerful, general teaching strategy of “concept mapping” must be replaced by alternative, specific strategies. Selected illustrative examples of students' learning difficulties and misconceptions in freshman general and organic chemistry are presented in the students' terms, followed by the corresponding successfully applied, specific, concept-oriented, eclectic intervention strategies the author uses in order to overcome the difficulties. Based on longitudinal in-class observations, interpretive study, and analysis it is suggested that those students' misconceptions in freshman chemistry which are not interrelated logically and/or derived from one another are not prone to the general “concept mapping” approach and should be dealt with by using the appropriate, specific teaching strategy. 相似文献

An element of current reform in science education worldwide is the shift from the dominant traditional algorithmic lower-order
cognitive skills (LOCS) teaching, to the higher-order cognitive skills (HOCS)-promoting learning; that is, the development
of students' capabilities including those of question asking (QA), critical/system thinking (CST), decision making (DM), problem
solving (PS), conceptualisation of fundamental concepts (CFC) and the transfer of these within both the science disciplines and real life interdisciplinary situations. Accordingly, an innovative metacognition-promoting
science teacher professional development course, integrating formal and informal science education, was developed and implemented
within a traditional model, focusing on the HOCS skills of QA, PS, and CFC. The HOCS promoting teaching and assessment strategies
of this course not only enabled participants to reflect on their own learning, but also facilitated their self-reflective
assessment, utilising a pre–post designed research-based methodology. The results suggest that such, or similarly appropriate,
metacognition-oriented courses can contribute positively to the development of science teachers' HOCS capability. 相似文献

The funding environment has a profound impact on researchers’ behavior. In particular, it influences their freedom and readiness to conduct research ventures with highly uncertain outcomes. In this conceptual paper, we propose a concise new methodology to evaluate researchers’ risk aversion based on citation statistics. The derived single-number criterion PR is sensitive to the ratio of high impact versus average impact work, based on citation counts. We demonstrate the usefulness of PR on a micro and meso level in the field of chemistry. PR is a potentially valuable tool for managers in higher education, to control for the impact of their funding instruments. The conducted testing may, in addition, contribute to the literature stream dealing with the effects of peer review in the allocation of research funding. Our results support the view that peer review fosters mainstream research. However, faculties with the highest percentages of third-party funding may find ways to avoid the restrictive effects. We also find evidence that permanent positions back risky research endeavors. 相似文献

The California Critical Thinking Disposition Inventory (CCTDI) was used to assess the disposition of Israeli and Italian high school and university science students toward critical thinking. The study sought to establish base-lines for these groups as well as quantifying the differences between two national populations. Significant differences between the Israeli and Italian high school science students in the total score and those of five subscales of the CCTDI have been found, the largest on the OpenMindedness and Self-Confidence subscales. The overall scores of high school and university science students on the CCTDI in both countries were essentially the same, with quite a similar pattern in the corresponding disposition profiles. Although the CCTDI can be reliably used for establishing base-line differences between science student populations, the effect of a specific approach to teaching (e.g. HOCS-orientation vs traditional) on the stability or change of this aspect of critical thinking remains an open question. 相似文献

Utilizing mixed methodology, this paper investigates the relationship between self-esteem and academic achievement for young adolescents within two Western cultural contexts: the United States and England. Quantitative and qualitative data from 86 North American and 86 British adolescents were utilized to examine the links between self-esteem and academic achievement from the beginning to the end of their academic year during their 11th–12th year of age. For both samples, quantitative results demonstrated that fall self-esteem was related to multiple indicators of later year academic achievement. While country differences emerge by the end of the year, math appears to have a consistent relationship with self-esteem in both country contexts. Qualitative analyses found some support for British students’ self-perceptions as more accurately reflecting their academic experience than the students from the United States. 相似文献

The California Critical Thinking Disposition Inventory (CCTDI) was used to assess the disposition of Israeli eleventh-grade science students toward critical thinking according to school type affiliate, scientific level, and gender. Our findings, strongly support (a) the establishment of a baseline reference for disposition toward critical thinking of high school science students; (b) the application of the CCTDI in the context of ongoing science education in different settings; and finally (c) the reliable use of the CCTDI in future research aiming at evaluating the effectiveness of critical thinking (CT) and higher-order cognitive skills (HOCS) oriented instructional goals. 相似文献

A specially-designed self-assessment questionnaire (SAQHOCS), containing higher-order cognitive skills (HOCS)-type questions, was administered to 71 biology majors, enrolled in a four-year college program. The gap between students' self-assessment marking, and that of their HOCS-biased teachers (the authors), is accounted for by the prevailing LOCS-orientation and the testing culture—a total separation between testing and learning—in contemporary science teaching. The majority of the students in the study evaluated themselves as capable of self-assessment, and felt reasonably confident in doing so. They were quite reserved as far as the applicability of the self-assessment method to nonalgorithmic (correct/incorrect) questions is concerned. The results of this study suggest that the potential for student self-assessment within college science teaching and learning exists. However, still a great purposed effort in HOCS-oriented teaching and learning is required in order for the student self-assessment practice to become a routine integral component of HOCS science examinations. 相似文献

The effectiveness of a smoking-prevention program—incorporated within a traditional science curriculum—was assessed in terms of attitude modification in such categories as health, peer pressure, and social image as related to smoking. The study indicates that most relevant attitudes, the emotionally intense in particular, are modifiable in the desired direction, although the changes are small. Some gender differences in the recorded changes suggest a difference in the dynamics of the response to smoking intervention between male and female high school students. A desired change of attitude frequency distributions (e.g., from less extreme to more extreme responses) has also been found. In addition, the tendency of the experimental students to actively act against smoking within family circles increased, although not significantly. All the above was accompanied by a decrease in the number of smokers in the experimental group and a significant increase in the number of smokers in the control group. These results suggest that it is educationally possible to modify attitudes in health education in the desired direction by means of a properly designed interdisciplinary science curricular unit implemented within ongoing traditional science teaching. 相似文献

Striving for sustainability requires a paradigm shift in conceptualization, thinking, research and education, particularly concerning the science-technology-environment-society (STES) interfaces. Consequently, ‘STES literacy’ requires the development of students’ question asking, critical, evaluative system thinking, decision making and problem solving capabilities, in this context, via innovative implementable higher-order cognitive skills (HOCS)-promoting teaching, assessment and learning strategies. The corresponding paradigms shift in science and technology education, such as from algorithmic teaching to HOCS-promoting learning is unavoidable, since it reflects the social pressure, worldwide, towards more accountable socially- and environmentally-responsible sustainable development. Since most of the STES- and, recently STEM (science-technology-engineering-mathematics)-related research in science education has been focused on secondary and tertiary education, it is vital to demonstrate the relevance of this multifaceted research to the science and technology teaching in primary schools. Our longitudinal STES education-related research and curriculum development point to the very little contribution, if any, of the traditional science teaching to “know”, to the development of students’ HOCS capabilities. On the other hand, there appears to be a ‘general agreement’, that the contemporary dominant lower-order cognitive skills (LOCS) teaching and assessment strategies applied in science and technology education are, in fact, restraining the natural curiosity and creativity of primary school (and younger?) pupils/children. Since creative thinking as well as evaluative system thinking, decision making, problem solving and … transfer constitute an integral part of the HOCS conceptual framework, the appropriateness of “HOCS promoting” teaching, and the relevance of science and technology, to elementary education in the STES context, is apparent. Therefore, our overriding guiding purpose was to provide any evidence-based research to the vital LOCS-to-HOCS paradigm shift in STES education. The findings of, and conclusions derived from our longitudinal research on HOCS development within STES-oriented and traditional education, suggest that both—science and technology education (STE) and STES education—are relevant to primary school education. Based on this, what it should take to insure success in this context, is thoroughly discussed. 相似文献

The trait anxiety profile of future science teachers, as well as their preferences concerning types of examinations in science and mathematics, have been surveyed prior to the administration—within the various science courses—of several traditional and nontraditional types of examinations and the assessment of students' state anxieties as well as their respective performance, i.e., their academic achievements. Our major findings are that
- (a) Our students prefer by far examinations in which the emphasis is on understanding and analyzing rather than on knowing and “remembering,” that the use of any relevant material during the examinations be permitted, and that the time duration be practically unlimited (e.g., “take-home”–type examinations).
- (b) Students' state anxiety correlates with the type of the examination, with a tendency towards somewhat higher anxiety for females. The preferred types of examinations reduce test anxiety significantly, and result in higher grades accordingly.
- (c) The reduction of anxiety and the improvement in achievements as a function of the examination type are far more significant for low achievers compared with medium and high achievers.
- (d) Although teachers are aware of the student preferences, they persist in giving their students their own “pet”-type examinations.
