This qualitative case study delved into students' understanding and positioning while they participated in solving an authentic, conceptually-based problem in a high-school chemistry class. Verbal and nonverbal cues, particularly gestures, offered broader awareness of students' engagement in sensemaking during the learning experience. The…

The purpose of this project was to investigate the effects of virtual versus physical manipulation using a simulation-based laboratory activity (SBL) and a microcomputer-based laboratory activity (MBL). Both the SBL and the MBL used computers to collect, graph, and analyze data. A major difference was that the MBL allowed the students to…

This study aimed to investigate the effect of experimenting with physical manipulatives (PM), virtual manipulatives (VM), and a blended combination of PM and VM on undergraduate students' understanding of concepts in the domain of "Light and Color." A pre-post comparison study design was used for the purposes of this study that involved 70…

We describe a study of programs to deepen families' scientific inquiry practices in a science museum setting. The programs incorporated research-based learning principles from formal and informal educational environments. In a randomized experimental design, two versions of the programs, called "inquiry games," were compared to two control…

One hundred years after its conception, the scientific method continues to reinforce a kind of cultural lore about what it means to participate in inquiry. As commonly implemented in venues ranging from middle school classrooms to undergraduate laboratories, it emphasizes the testing of predictions rather than ideas, focuses learners on material…

The laboratory has been given a central and distinctive role in science education, and science educators have suggested that rich benefits in learning accrue from using laboratory activities. Twenty years have been elapsed since we published a frequently cited, critical review of the research on the school science laboratory (Hofstein & Lunetta,…

Describes the results of a study on the similarities and differences in laboratory tasks used in science education at upper secondary school and university level in the three main science subjects in seven European countries. Some differences are noted between the science subjects and educational levels, but the dominant impression of the analysis…

Discusses the development of a student's ability to control experiments as an important aim of modern science curriculum materials. Argues that most curriculum developers offer only a simplistic method of controlling variables. Suggests ways to enhance the development of variable control within the framework of student experiments. (TW)

The purposes of this study were to (a) gain an understanding of the views of inquiry held by faculty members involved in undergraduate science teaching and (b) describe the challenges, constraints, and opportunities that they perceived in designing and teaching inquiry-based laboratories. Participants included 19 college professors, representing…

There is widespread concern for the situation of school physics regarding recruitment, contents, teaching methods, etc. In this study based on questionnaire and focus group data, we explore how upper secondary pupils and teachers perceive physics as a subject, how they experience physics instruction, and how physics compares to other subjects. Our…
