Idea development in the early phases of the design process often involves the transformation of initial concepts into more feasible alternatives. However, this important component of design activity is often under-emphasized in design education, and tools to facilitate iteration of designs are limited. This study investigated "Design…

In this study, we analyzed the descriptive knowledge and mental models of the phenomenon of tides manifested by 111 preservice primary teachers. The instrument employed is an open-ended questionnaire, analyzed by means of an approach that explores the descriptions, explanations, and predictions in respect of this phenomenon by our subjects. First,…

Engineering students need to prepare to address increasingly complex, contextual, and ambiguous problems in their future careers. Many students pursue engineering to improve societal problems and create innovative solutions. Yet, divergent thinking needed for creativity, and the consideration of multiple social issues and a variety of contexts, is…

The purpose of this study was to investigate the development of pre-service chemistry teachers' (PCTs') argumentation skills in a laboratory course throughout a semester. A case study design was utilised. A total of six PCTs participated in the study. To investigate the development of PCTs' argumentation skills, the laboratory reports that were in…

Chemical processes can be fully explained only by employing quantum mechanical models. These models are abstract and require navigation of a variety of cognitively taxing representations. Published research about how students use quantum mechanical models at the upper-division level is sparse. Through a mixed-methods study involving think-aloud…

In teaching proportion, the teachers usually give the students a formal formula, such as cross-multiplication, without providing them the meaning of proportionality. Thus, the students just apply it in order to solve proportional problems. However, it does not connote that they understand what proportionality means. In this paper, the authors…

Discusses Vee mapping, a technique to assist students in categorizing the relationship between the conceptual and procedural aspects of science. Presents a study to investigate elementary education majors' (n=27) use of the Vee heuristic and concept mapping for the construction of knowledge; attitudes toward learning science in collaborative…
