Research apprenticeships for secondary students provide authentic contexts for learning science in which students engage in scientific investigations with practicing scientists in working laboratory groups. Student experiences in these research apprenticeships vary depending on the individual nature of the laboratory in which students have been…

This study was designed to examine students' use of multiple modal representations within their written arguments as a consequence of completing a series of investigations of an organic chemistry laboratory course. One hundred and eleven students from a major Midwestern university were involved in using the Science Writing Heuristic (SWH) approach…

We examine the respective roles of substantive understanding (i.e., understanding of factual knowledge, concepts, laws and theories) and procedural understanding (an understanding of ideas about evidence; concepts such as reliability and validity, measurement and calibration, data collection, measurement error, the ability to interpret evidence…

With the growing emphasis on the development of scientific inquiry skills, there is a strong need for more research on students' ability to collect and interpret evidence. This paper calls attention to the notion of evidentiary competence that refers to the concepts and reasoning skills involved in the collection, organization, and interpretation…

A debate is ongoing in Hong Kong regarding whether local and international schools vary in the extent to which they provide classroom learning environments that support the development of students' higher order thinking and metacognition. This study investigated commonalities and variations in the metacognitive orientation of local and…

Investigates students' (N=277) performance and the effects of pre-training on tasks rated high in ambiguity, in particular those where the solution to the tasks cannot be arrived at through predictable algorithms. Findings show pre-training to be a significant factor in improving students' ability to plan and carry out open-ended investigations.…

This article reports on the third year of a three-year longitudinal investigation into six secondary students' understanding of optics at a secondary school level. In the third year of this investigation the students, who by now were in Year 12, underwent a teaching sequence that centred on the teaching and learning of physical optics and quantum…

The purpose of this investigation was to apply a validated curriculum evaluation instrument, the "Science Curriculum Implementation Questionnaire" (SCIQ), in an educational context in which a science curriculum review had recently been completed and, by so doing, ascertain the accuracy and potential value of the instrument as a…
