Negotiation of Dialectical Contradictions by Parents who have Experienced the Death of a Child

This study examines how bereaved parents experience communicating with individuals in their social network. The bereaved parents in this study experienced two dialectical contradictions: (a) between the physical absence of their child and the continuing presence and emotional bond with their deceased child; and (b) between being open or closed when deciding whether to talk about the deceased child to others. Results describe how parents communicatively negotiated these contradictions. The article concludes by discussing practical applications for bereaved parents, bereavement support groups, helping professionals, and individuals within the bereaved parents' social network.     

The disposition toward critical thinking of high school and university science students: an interintra Israeli-Italian Study

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.

The Disposition of Eleventh-Grade Science Students Toward Critical Thinking

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.     

Student Self-Assessment in HOCS Science Examinations: Is There a Problem?

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.     

Model-Based Teaching and Learning with BioLogica™: What Do They Learn? How Do They Learn? How Do We Know?

This paper describes part of a project called Modeling Across the Curriculum which is a large-scale research study in 15 schools across the United States. The specific data presented and discussed here in this paper is based on BioLogica, a hypermodel, interactive environment for learning genetics, which was implemented in multiple classes in eight high schools. BioLogica activities, data logging, and assessments were refined across this series of implementations. All students took a genetics content knowledge pre- and posttests. Traces of students' actions and responses to computer-based tasks were electronically collected (via a log file function) and systematically analyzed. An intensive 3-day field test involving 24 middle school students served to refine methods and create narrative profiles of students' learning experiences, outcomes, and interactions with BioLogica. We report on one high school implementation and the field test as self-contained studies to document the changes and the outcomes at different phases of development. A discussion of design changes concludes this paper.     

Attitude modification in health education through an interventive,antismoking program incorporated within traditional science curriculum

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.
