The effectiveness of using computer simulated experiments on junior high students' understanding of the volume displacement concept

Several researchers have suggested that the computer holds much promise as a tool for science teachers for use in their classrooms (Bork, 1979, Lunetta & Hofstein, 1981). It also has been said that there needs to be more research in determining the effectiveness of computer software (Tinker, 1983). This study compared the effectiveness of microcomputer simulated experiences with that of parallel instruction involving hands-on laboratory experiences for teaching the concept of volume displacement to junior high school students. This study also assessed the differential effect on students' understanding of the volume displacement concept using sex of the students as another independent variable. In addition, it compared the degree of retention, after 45 days, of both treatment groups. It was found that computer simulated experiences were as effective as hands-on laboratory experiences, and that males, having had hands-on laboratory experiences, performed better on the posttest than females having had the hands-on laboratory experiences. There were no significant differences in performance when comparing males with females using the computer simulation in the learning of the displacement concept. This study also showed that there were no significant differences in the retention levels when the retention scores of the computer simulation groups were compared to those that had the hands-on laboratory experiences. However, an ANOVA of the retention test scores revealed that males in both treatment conditions retained knowledge of volume displacement better than females.     

Supporting the transition to inclusive education: teachers’ attitudes to inclusion in the Seychelles

The inclusion of children with disability in regular classroom settings has been identified worldwide as crucial to the provision of effective education for all children and to the creation of more inclusive societies. To this end there has been significant focus on pre-service and in-service teacher education to ensure that teachers are adequately prepared to teach in inclusive classrooms. When delivering a unit on inclusive education in the Seychelles, which was developed in Australia, we considered it essential to determine the suitability of the unit in supporting Seychellois teachers to teach inclusively. Teachers’ attitudes and beliefs about people with disability are two aspects that have consistently been shown to impact on a teacher’s willingness to include children with disability. Therefore, the Seychellois teachers were asked to complete questionnaires in the first and final weeks of the semester in which the teachers undertook the unit. The two sets of responses were analysed to determine significance and effect sizes of any change in attitudes and beliefs. Data revealed that the Seychellois teachers reported more positive attitudes and beliefs about the inclusion of children with disability in regular classrooms after completing the unit, suggesting that the unit of study was suitable for the Seychellois context.     

Cognitive style and instructional preferences

The aim of the study was to investigate the relationship between learners' cognitive styles and their instructional preferences. The sample consisted of 240 business studies students at a UK university. Subjects' cognitive styles were assessed using the Cognitive Styles Analysis (which assesses the wholist-analytical and verbaliser-imager dimensions of style) and their instructional preferences assessed using an instructional preferences inventory which consisted of three sub-inventories (instructional method, instructional media and assessment method). Overall subjects favoured dependent methods, print based media and informal assessment methods. There was a significant main effect of wholist-analytical style on collaborative method preference (role play, group discussions and business games) and non-print based media preference (overhead transparencies, slides and videos). There was an interaction of the two dimensions of style and gender in their effect on informal assessment method preferences (individual and group assignments and multiple choice and short answer-type questions). The findings are discussed in terms of: (i) models of the cognitive style construct; (ii) the practical implications of individual differences in style and preference.     

How Research,Teaching, and Leadership Roles are Recommended to Male and Female Engineering Faculty Differently

Research in Higher Education - Across disciplines, male faculty spend more time on research than female faculty. Yet, women tend to teach and mentor students more hours than men (Misra et al. in...     

What Is Right About Special Education

Abstract

Promoting self-determination has become an important aspect of the educational programs of students with disabilities. There is now a sufficient literature base to support some syntheses that enable researchers to judge their progress in this area to date and to provide direction for future research and practice. For this study, we conducted a literature review of studies that measured or examined global self-determination.     

Gender,prior knowledge,interest, and experience in electricity and conceptual change text manipulations in learning about direct current

The present study investigated relationships between gender, interest and experience in electricity, and conceptual change text manipulations on learning fundamental direct current concepts. Conceptual change text has been shown to lead to better conceptual understanding of electrical concepts than traditional didactic text, but previous research suggested that the effect interacted with the gender of the participants. We hypothesized that interest moderated this interaction. In this study, men and women who had higher or lower interest in electricity and greater or lessor experience with electricity read conceptual change or traditional text. When interest level, experience, and prior knowledge were not included in the analysis, both gender and text type produced significant main effects. When interest level, experience, and prior knowledge were included in the analysis, conceptual change text led to better understanding of electricity concepts than did the traditional text, and the effect of gender was eliminated. This finding supports the hypothesis that prior interest level, experience, and knowledge mediate apparent gender differences in learning about electricity. It suggests that conceptual change text manipulations are likely to be effective for both men and women. © 1997 John Wiley & Sons, Inc. J Res Sci Teach 34: 107–123, 1997.
