Informal learning environments such as Natural History Museums can introduce visitors to a variety of topics in evolution by providing accessible representations of concepts like geological time, evolutionary mechanisms, biological diversity, geological time, and fossil dating. Our study examined sixth-grade students' conceptualization of…

This article reports the results of an ethnographic research about the multimodal science discourse in a sixth-grade sheltered classroom involving English Language Learners (ELLs) only. Drawing from the perspective of multimodality, this study examines how science learning is constructed in science lectures through multiple semiotic resources,…

Research has identified the value of learners using technology to construct their own representations of science concepts. In this study, we investigate how learners, such as preservice elementary teachers, design and make a narrated animation to represent their science knowledge. The type of animation exemplified is called a "Slowmation"…

Explores relationships among school students' (n=189) acquisition of meaningful understandings of protein synthesis. Analysis of student-generated analogies revealed unique patterns in students' understandings of this topic. Contains 41 references. (Author/WRM)

Presents data which leads to the construction of a response to the question of how different phases of the learning cycle influence physics students' content achievement and attitudes. Discusses the importance of the learning cycle in science instruction and the strength of using contrasting techniques (qualitative and quantitative) in research.…

Presents study findings which explored the effect of teacher reasoning level and teaching style preference on improvement in student-reasoning ability. Reports that students of concrete operational teachers and of inquiry teachers showed greater gains in reasoning ability than students of formal operational teachers and of expository teachers. (ML)
