Recent experience has demonstrated that for an aged researcher, teaching secondary school science at a selective high school
while committed to carrying out research in science education is riddled with difficulties. With respect to the research,
problems ranged from there being too much time required to establish one's credentials as a teacher, to too much research
being too easily suggested and undertaken. With respect to the teaching, among other things, it was too time-consuming, there
were too many other duties to perform and other teachers became too involved in one's own interests. To make matters worse,
there were too many students, they were too varied, too interesting and the relationship with them became too rewarding. A
thoroughly disturbing state of affairs.

The general aim of our human nutrition project is to develop a health education model grounded in ‘everyday’ or ‘situated’
cognition (Hennessey, 1993). In 1993, we began pilot work to document adult understanding of human nutrition. We used a HyperCard
stack as the basis for a series of interviews with 50 adults (25 university students, and 25 adults from offcampus). The interviews
were transcribed and analysed using the NUDIST computer program. A summary of the views of these 50 adults on selected aspects
of human nutrition is presented in this paper.

This study explored the interactions of a highly motivated group of students doing traditional practical work in science.
Interest focussed on the social construction of understanding and how this could be described. Despite considerable collaboration
in constructing an understanding of the task the students rarely focussed on the concepts the practical work was intended
to illustrate. Collaboration was described in terms of social behaviours and discourse moves which supported the use of cognitive
strategies.

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.

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.

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. 相似文献

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. 相似文献
