Investigates differences in marking standard and reliability when experienced teachers carried out assessments of the performance on practical exercises. The results showed that there was no difference between the assessments from the groups containing 5 and 20 students. (Author/YP)

Explores the concept of construct validity in the context of a public examination. Multitrait-multimethod analysis and factor analysis were used. Discusses the analyses in terms of theory versus practical components and experimental versus observational investigation in practical components. Sample items for the practical examinations are…

The purpose of this study was to identify interest patterns related to high school biology. Eight task dimensions were established before testing. Findings include: the highest interest was in human biology topics and students whose parents' employment was science related showed higher interest in biology. (CW)

The purpose of this study was to determine the socio-cultural factors which mitigate against the learning and teaching of science in the secondary school. It was found that authoritarianism, goal structure, the African world-view, societal expectation, and sacredness of science have significant effects on the learning of science. (CW)

This paper examines the affective components which were an integral part of science goals of the 1980's using data from the Second IEA Science Study in the United States. Data indicated that students in the United States were generally positive about chemistry and science. (CW)

This study assessed the achievement of 14/15 year-old pupils related to technology. The total mean score for the boys was significantly higher than that of the girls. Father's education was significantly related to achievement. (Author/CW)

Reported is a study of the relationships between the component skills involved in practical work assessment. Skills assessed included observing, manipulating, planning, interpreting, reporting, and self-reliance. The literature relating to inter-skill relationships is reviewed. (CW)

Assesses the ability of tenth grade students (n=364) to acquire meanings of graphs that are frequently used in their biology textbooks. Indicates that the main source of failure to process information equally well from tables and graphs was not a lack of basic analytical skills but rather a lack of understanding of the relationship between…

Scrutinizes the assessment of students' practical skills, in an honors-level biology examination, for construct validity utilizing both correlational and factor analytical methods to explore relationships between students' practical (laboratory) and theoretical (written) performances. Indicates that teacher assessment of practical skills resulted…

Describes the use of concept mapping (CM) in design, instruction, and assessment related to microbiology lessons prepared for high school students in Israel. Indicates that students utilizing CM displayed an overall, higher achievement gain than students in traditional classes. Recognizes that some teachers did not thoroughly exploit the potential…

Reports on findings from an interpretive team study of the teaching/learning environments in the science program at an innovative Australian high school, in which 778 students perform laboratory and classroom activities within a self-paced, independent framework. Suggests that the knowledge that teachers require to undertake effective science…

The purpose of this study was to examine interpersonal behaviour in psychosocial learning environments and to determine the associations between science students' perceptions of their interactions with their teachers, the cultural background of teachers and their attitudinal outcomes.
