Inter-relationship among laboratory process skills in biology

Inquiry oriented practical matriculation tests of 3650 12th grade biology students in Israel were analyzed to find out the interrelationships among 21 process skills. Using correlations and varimax factor analysis, seven factors were obtained. These factors are listed according to the relative percentage of the total variance accounted for from highest to lowest: handling quantitative relationships, explaining and assessing data, conceptualizing and planning investigations, summarizing results, interpreting and concluding, selecting form of presenting findings, designing experiments. The theoretical and practical implications of these findings are briefly discussed. Theoretically, the associations as well as the dissociations identified provide important clues regarding the organization of process skills related knowledge in cognitive structure. From a practical perspective the findings offer guidance for teacher educators as well as biology teachers on more effective ways for developing science process skills.     

Evaluation Practices in Teacher Education in Israel

Evaluation procedures and the emphasis on evaluation in teacher education courses in Israel were studied through questionnaires administered to teacher educators, student teachers and practicing teachers. The results show that the emphasis on evaluation is marginal and that evaluation procedures in teacher education have significant effects on practicing teachers.     

Meta-analysis of cognitive preferences and learning

Most of the articles and dissertations dealing with cognitive preferences which were written since the invention of the construct in the early 1960s have been reviewed. Fifty-four of them were found suitable for meta-analysis. The meta-analysis presents means and standard deviations of reliabilities, correlations, standard scores, and effect sizes. The effects and relationships of cognitive preferences and important school and learning related variables were studied. The results provide base line data for comparative purposes and offer empirical evidence which support the construct validity of cognitive preferences.     

THE CLASS‐SIZE EFFECT UPON ACTIVITY AND COGNITIVE DIMENSIONS OF LESSONS IN HIGHER EDUCATION

This study examines the effects of class size upon the verbal interactions and the cognitive level of medical instruction. The major findings of this study indicate that: (a) the percentage of the teacher's verbal activities increases with the group size; (b) the shortest teacher‐lectures are given in medium‐size classes; (c) the longest student‐answers and student initiations are observed in medium‐size classes; (d) the maximal diversity of verbal interactions is found in medium groups, while the minimal is found in large groups; (e) the percentage of interactions at the lowest cognitive level (knowledge) increases with class size; (f) longer interactions are observed in large classes at the knowledge level, and in smaller classes at the analysis and evaluation levels; (g) the minimal cognitive diversity is found in large groups; (h) both activity and cognitive total scores decrease as the class size increases. The implications of these findings are discussed.     

The Israeli “bagrut” examination in biology revisited

The Israeli paper-and-pencil matriculation examination in biology has been one of the most powerful means for implementing an inquiry oriented high school biology program based on the U.S. BSCS. The first version of this examination was described and analyzed in JRST in 1972. This article describes the changes and effects of this examination during the years and compares the examination of the year 1982 with that of 1969. Implications for upgrading science education are discussed.     

Not All Countries Are Created Equal: Foreign Countries Prevalence in U.S. News and Entertainment Media

Why do some countries appear more popular than others in mass media? Although researchers have long sought to explain foreign countries’ prevalence in the media, to date they have exclusively focused on news, leaving other types of media content unexplored. In addition, focusing on media effects and media content, the literature on entertainment and politics has largely ignored the study of agenda-building processes. Thus, this study fills these gaps by exploring factors affecting the volume of references to foreign countries in both U.S. news and entertainment media. Analyzing more than 400 U.S. television shows, four news channels, and two newspapers spanning from 2000 to 2011, we reexamine past findings on salience of foreign countries in the news and apply these findings to a new field of research, entertainment media. We further suggest that the same factors shaping foreign countries’ prevalence in the news media are applicable to both news and entertainment and that in the context of foreign countries’ prevalence, the criteria for “newsworthiness” and “fictionworthiness” is similar.
