The present study explores the relationship between students' views of the nature of science (NOS) and their views of the nature of scientific measurement. A questionnaire with two-tier diagnostic multiple-choice items on both the NOS and measurement was administered to 179 first-year physics students with diverse school experiences. Students'…

This paper describes a course aimed at developing understanding of measurement and uncertainty in the introductory physics laboratory. The course materials, in the form of a student workbook, are based on the probabilistic framework for measurement as recommended by the International Organization for Standardization in their publication "Guide to…

An evaluation of a course aimed at developing university students' understanding of the nature of scientific measurement and uncertainty is described. The course materials follow the framework for metrology as recommended in the "Guide to the Expression of Uncertainty in Measurement" (GUM). The evaluation of the course is based on…

This paper reports the findings of two systematic reviews of the use and effects of small group discussions in high school science teaching. Ninety-four studies were included in an overview (systematic map) of work in the area, and 24 studies formed the basis of the in-depth reviews. The reviews indicate that there is considerable diversity in the…

This paper reports on the use of out-of-school everyday contexts in Namibian science classrooms. This use is portrayed against the backdrop of an explicit educational philosophy of learner-centred teaching. Data were collected through audio-taped teacher-learner interactions and non-participant field notes in 29 junior and senior science classes…
