Self-efficacy and science anxiety among preservice primary teachers: Origins and remedies

The preservice training of primary teachers is an opportunity to provide positive experiences which may ameliorate students' anxiety about science and science teaching, and enhance their beliefs that they may become effective science teachers. The previous and current science related experiences, and beliefs, of an intake of primary teachers participating in an introductory science content subject, were explored. Matter and energy concepts were major content components of the subject. Data were collected from pre- and post-test administrations of psychometric tests designed to measure students' science teaching self-efficacy, science related attitudes, interest in science teaching, and preferred learning environment. A randomly selected sample of students was interviewed at the commencement and finish of the subject. One third of the sample was assigned to a study group in which a constructivist approach to laboratorys sessions was adopted. The remainder of the sample experienced a more traditional transmissive format in laboratory sessions. Analysis of the quantitative data revealed no group differences in self-efficacy. Interesting contrasts between students evident in the data from the interviews facilitated the articulation of tentative assertions about the causative factors that may influence the development of students' sense of self-efficacy and possible science related anxiety.

A constructivist approach to secondary school science experiments

The focus of this study was on the investigation of a laboratory instructional program on electricity designed for conceptual development using constructivist principles for conceptual change. This approach was compared with a traditional laboratory approach in a quasi-experimental design. The sample was 247 grade 10 students (boys) in a large non-government urban school. Covariance analysis with the corresponding pretest as covariate showed statistically and educationally significant gains for the experimental group on cognitive but not attitudinal outcomes when compared to the traditional group. Student and teacher interview data provide some evidence for the success of the experimental approach. Specializations: physics education, constructivist approaches to in practical work. Specializations: science teacher education, learning environments, conceptual change.     

What Undergraduates Misunderstand about Stem Cell Research

As biotechnology‐related scientific advances, such as stem cell research (SCR), are increasingly permeating the popular media, it has become ever more important to understand students’ ideas about this issue. Very few studies have investigated learners’ ideas about biotechnology. Our study was designed to understand the types of alternative conceptions students hold concerning SCR. The qualitative research design allowed us to examine college students’ understandings about stem cells and SCR. More specifically, we addressed the following questions: How can alternative conceptions about stem cell topics be categorized? What types of alternative conceptions are most common? Participants included 132 students enrolled in a biotechnology course that focused on the scientific background of biotechnology applications relevant to citizens. In this study, we used an inductive approach to develop a taxonomy of alternative ideas about SCR by analyzing student responses to multiple open‐ended data sources. We identified five categories of conceptions: alternative conceptions about what, alternative conceptions about how, alternative conceptions about medical potential, terminology confusion, and political and legal alternative conceptions. In order to improve instruction, it is important to understand students’ ideas when entering the classroom. Our findings highlight a need to teach how science can be applied to societal issues and improve science literacy and citizenship.     

Teachers’ Ratings,Sex, and SCAT as Predictors of Rank in High School Class

Data from 561 high-school seniors were analyzed using multiple linear regression to determine the independent contribution of each variable to the criterion of rank in class (R). Significant F ratioswere obtained for SCAT V and Q, teachers’ ratings of Accuracy (ACCU), Effort and Industry (E-I), and Reliability and Responsibility (R-R). R-R and ACCU, but not E-I, were found to be significant preditors of SCAT V and SCAT Q. Females were significantly higher than males on R, ACCU, E-I, and R-R and lower on SCAT Q. The data were interpreted as supporting the effectiveness of teachers’ ratings in predicting academic performance in high school. Females’ superior performance on teacher ratings was interpreted as evidence that females conformed more than males to teachers’ expectations.     

Towards a unified theory for HIV/AIDS counselling

The paper explores the introduction of an unified theory for HIV/AIDS counselling. To date the provision of HIV/AIDS counselling has been largely based upon the behavioural theory of counselling. This theory has been adopted by WHO/GPA and its main aims have been the prevention of HIV infection and the psychosocial support for those already infected. It is argued that future counselling interventions should be redirected from a disease-centred approach to a person centred approach. This redirection can be facilitated by the adoption of the self concept as the central measure for evaluating change. It is argued that various ideas should be selected from the behavioural, psychoanalytical and humanistic theories of counselling. These ideas should be amalgamated into a unified theory which provides the theoretical foundation upon which a comprehensive counselling intervention can be based.
