Thinking about television science: How students understand the nature of science from different program genres

Student views on the nature of science are shaped by a variety of out‐of‐school forces and television‐mediated science is a significant force. To attempt to achieve a science for all, we need to recognize and understand the diverse messages about science that students access and think about on a regular basis. In this work I examine how high school students think about science that is mediated by four different program genres on television: documentary, magazine‐format programming, network news, and dramatic or fictional programming. The following categories of findings are discussed: the ethics and validity of science, final form science, science as portrayed by its practitioners, and school science and television science. Student perceptions of the nature of science depicted on the program sample used in this study ranged from seeing science as comprising tentative knowledge claims to seeing science as a fixed body of facts. © 2003 Wiley Periodicals, Inc.

Teacher-student classroom interactions among science students of different sex and cultural background

The purpose of this study was to determine associations between science students' perceptions of their interactions with their teachers, the cultural background of students and their attitudinal and cognitive achievement outcomes. A sample of 3,215 students from 158 secondary school science classes in 43 schools completed a survey including the Questionnaire on Teacher Interaction (QTI), an attitude to calss scale, an enquiry skills scale and questions relating to cultural background. The sample was chosen in order tobe representative, though only coeducational classes were used in order to permit an unconfounded test of sex differences. Statistical analyses confirmed the reliability and validity of the QTI for secondary school science students. Generally, the dimensions of the QTI were found to besignificantly associated with student attitude scores. In particular, students' attitude scores were higher in classrooms in which students perceived greater leadership, helping/friendly, and understanding behaviours in their teachers. Correlations between cognitive achievement and interpersonal behaviour were not as strong, but there were positive associations with cooperative behaviours and negative associations with oppositional behaviours. Females perceived their teachers in a more positive way than did males and students from an Asian background tended to perceive their teachers more positively than those from the other cultural groups identified in the study.

The effectiveness of orienting students to the physical features of a science museum prior to visitation

This paper reports on a study in the area of informal science education in the contexts of science museums. The research focused upon two areas: first, perceived novelty and its effect on cognitive learning in year eight students visiting an interactive science museum; second, the links between exhibits which were most frequently recalled and exhibits which students later recalled as being interesting and puzzling. Results on a post-test of cognitive learning of concepts and principles associated with the exhibits suggested that students who underwent novelty reducing pre-orientation to the physical environment and had prior visitation experience learned more than their counterparts. Gender did not influence learning when perceived novelty level and prior exposure were considered. Furthermore, the most frequently recalled exhibits shared a combination of characteristics such as large physical size, prominence in the exhibit galleries, and the diversity of sensory modes that they employed. Finally, it appears that cognitive learning is likely to occur for exhibits which are most memorable.     

Towards a theoretical basis for students' alternative frameworks in science and for science teaching

As there is nothing as practical as a good theory, there is a continuing need in the field of science education enquiry to look for theories which help to interpret the findings about students' alternative frameworks and to inform the design of teaching strategies which relate to a research focus on ‘how the student learns’. The developmental model of cognitive functioning based on the SOLO Taxonomy (Biggs & Collis, 1982) as updated in 1991 (Biggs & Collis, 1991; Collis & Biggs, 1991) is being applied in this way. Questionnaire data from two large studies of science learning of Australian students (conducted by ACER and NBEET) are being re-analysed in terms of the current theory. This paper illustrates the theory and describes a plan of further research. Specializations: science education, students' understandings of phenomena in science. Specializations: cognitive development, evaluation, mathematics and science education. Specializations: mathematics education, students' understanding of chance and data concepts.     

The effectiveness of conceptual change texts in remediating high school students’ alternative conceptions concerning chemical equilibrium

This study investigated the effectiveness of conceptual change texts in remediating high school students’ alternative conceptions concerning chemical equilibrium. A quasi-experimental design was used in this study. The subjects for this study consisted of a total 78 tenth-grade students, 38 of them in the experimental group and 40 of them in the control group. A questionnaire, the Alternative Conceptions about Chemical Equilibrium Test (ACCET), was developed and administered to students as a pretest and posttest. While the experimental group received a conceptual change text instruction, the control group received a traditional style instruction. The results of the study indicated that the students in the experimental group showed significantly greater levels of achievement than the students in the control group. Moreover, in both groups the percentages of students’ alternative conceptions decreased in the however the experimental group did better than the control group.
