In studying the River Continuum Concept, groups of students undertake a series of interrelated projects as a means of understanding the big picture of the food and energy interrelationships evident in healthy…

For most students textbooks are the main source of their information about scientific concepts; however, there are a number of errors which frequently appear in textbooks and are consequently transmitted to both teachers and students. Some of these errors which may represent widespread misconceptions of teachers are outlined. (Author)

This table illustrates when, why, and how computer-based information technology best lends itself to learning in science classrooms. It aims to illustrate the potential of this technology and some of the thinking and planning that is necessary for successful, effective classroom use. Application types include data collecting devices, spreadsheets,…

Year 11 students investigated the real-world problem of whether screws are really brass. It allowed them to use the colorimeter and computer interface in a way that was easily understood and models normal practice in testing laboratories. Screws were dissolved in nitric acid and their absorbance of red light was compared with a standard curve.…

Examines student and teacher perceptions about the purpose and effectiveness of laboratory work at Year 10. The views of students and their teacher on the goals, conduct, and assessment of laboratory work were compared.
