The Index of Forecasting Efficiency,for the Case of a “True” Criterion

A variety of personal characteristics have been shown to be influential in teacher-student relationships. The sex of the child as well as the appropriateness of his behavior were the factors evaluated in this study. An analysis of the results indicated that sex-inappropriate behavior was viewed less favorably than sex-appropriate behavior. A discussion of the results was presented with regard to support for previous studies and implications for future research.     

The Development of Productive Thinking Skills in Fifth-Grade Children

A controlled experiment was conducted in forty-four fifth-grade classrooms to investigate the extent to which creativity and problem-solving skills of children could be nurtured through a series of self-instructional programmed lessons. Also studied was the relationship of such skills to (1) learner characteristics (IQ and sex) and (2) classroom “environment” as it may have facilitated creative thinking. Significant differences were found favoring the experimental group (which received the programmed lessons). Improvement in productive thinking skills was found for both boys and girls of both higher and lower IQ. Greater gains were found in classrooms providing relatively little support and encouragement for productive thinking. Also the performance of girls on the productive thinking measures exceeded that of boys and there was a strong positive relationship to IQ.     

Emotional arousal of beginning physics teachers during extended experimental investigations

Teachers often have difficulty implementing inquiry‐based activities, leading to the arousal of negative emotions. In this multicase study of beginning physics teachers in Australia, we were interested in the extent to which their expectations were realized and how their classroom experiences while implementing extended experimental investigations (EEIs) produced emotional states that mediated their teaching practices. Against rhetoric of fear expressed by their senior colleagues, three of the four teachers were surprised by the positive outcomes from their supervision of EEIs for the first time. Two of these teachers experienced high intensity positive emotions in response to their students' success. When student actions/outcomes did not meet their teachers' expectations, frustration, anger, and disappointment were experienced by the teachers, as predicted by a sociological theory of human emotions (Turner, J. H. (2007). Human emotions: A sociological theory. London, England: Routledge). Over the course of the EEI projects, the teachers' practices changed along with their emotional states and their students' achievements. We account for similarities and differences in the teachers' emotional experiences in terms of context, prior experience, and expectations. The findings from this study provide insights into effective supervision practices that can be used to inform new and experienced teachers alike. © 2012 Wiley Periodicals, Inc.

Construct validity of self-concept in TIMSS’s student background questionnaire: a test of separation and conflation of cognitive and affective dimensions of self-concept among Saudi eighth graders

The aims of this study are to: (a) assess if cognitive self-concept (competence) and affective self-concept in mathematics and science are different constructs, (b) evaluate the construct validity of self-concept in the context of conflation and separation, and (c) test if the relationships among cognitive and affective variables are invariant across gender. The data for this study were obtained from the Trends in International Mathematics and Science Study 2007 database. Data about 2,687 out of 4,099 eighth grade Saudi students were subject to various analyses. The variables used in this study were mathematics and science self-concepts, and mathematics and science subject value as part of the Students Background Questionnaire. The relationships among constructs were examined with the use of SPSS16 and the structural equation modeling software, AMOS16. The results demonstrated that subject value and self-concept were different constructs. Also, the results demonstrated that cognitive and affective self-concepts were independent, but strongly related constructs, and the structure of the construct was clearer when self-concept was separated into cognitive and affective components than when it was conflated. The relationships among cognitive, affective, and subject value in mathematics and science were invariant across gender. However, their relationships with achievement were not invariant across gender.     

A tool for changing the world: possibilities of cultural‐historical activity theory to reinvigorate science education

Cultural‐historical activity theory, an outcrop of socio‐psychological approaches toward human development, has enjoyed tremendous growth over the past two decades but has yet to be appropriated into science education to any large extent. In part, the difficulties Western scholars have had in adopting this framework arise from its ontology, which is materialist dialectical and, hence, does not allow easy absorption into non‐dialectical (classical logical) thinking underlying much of Western scholarship. Cultural‐historical activity theory has tremendous potential because it sublates traditional dichotomies in everyday teaching‐learning situations including individual/collective, body/mind, intra‐/inter‐psychological, cognitive/emotive and psychological/sociological. In this contribution, we not only review the existing literature that uses or develops this non‐dualistic approach, but also articulate an intelligible explication of the theory that is more accessible to Western scholars and describe possible future curriculum work and research in science education as an expression of the fruitfulness of the theory.
