Abstract

Previous research has shown that students at almost all levels have misconceptions about both the shapes and sizes of celestial bodies in space. This study is essential to conduct on the students who take space topic in their schools for the first time This study aims at revealing fifth-grade students’ alternative conceptions about the size of the sun, earth, and moon and their relative positions to each other. This study employs action research by using a forced questionnaire and interview were used as the research instruments and involved 78 fifth-grade students as participants. To collect data, all students initially responded to a forced question questionnaire. Then, based on their responses, four students were chosen to be interviewed to clarify their alternative conceptions. The data analysis was carried out using interview and questionnaire data to reveal understanding and alternative conceptions of students’ responses. The results found that students had alternative conceptions of the earth’s shape in their minds. Moreover, alternative conceptions are commonly found in the sun, earth and moon positions.

Abstract

Numerous studies demonstrated that the meaning-making of scientific knowledge is affected by the design of multimodal science texts. Various modes are co-operated together in certain inter-semiotic mechanisms to produce meaning in multimodal texts. Based on this perspective, this research seeks to investigate the effect of mode level in science texts and compositional arrangement on the meaning-making of science concepts and processes. In this context, four science texts with the same content (transformation of energy) at different mode densities and two science texts with the same content (covalent bonding) one of which is arranged in accordance with variation theory of learning are designed. By using the case study method, this research explored six experienced science teachers’ views about the effects of mode level and multimodal text composition on meaning-making. The data were collected with semi-structured interviews. The thematic analysis was employed for data analysis. The findings demonstrated that mode density may affect meaning-making and so learning since different modes have affordance to represent different meaning and meaning relationship types. Besides, multimodal text composition may foreground the critical aspects of content, and help to design a coherent multimodal science text.
