Ergazaki, Marida; Andriotou, Eirini – Research in Science Education, 2010
This study aims at highlighting young children's reasoning about human interventions within a forest ecosystem. Our focus is particularly set on whether preschoolers are able to come up with any basic ecological interpretations of human actions upon forest plants or animals and how. Conducting individual, semi-structured interviews with 70…

Format-Free Databases and the Construction of Knowledge in Primary School Science Projects.
Peer reviewed Peer reviewed
Nason, Rod; And Others – Research in Science Education, 1996
Reports on a study in which a teacher used the collaborative development of a format-free computer database to facilitate the construction of knowledge by a group of students (n=3) during a science project. Results indicate that knowledge construction is enhanced when children collaboratively develop a format-free database. Contains 27 references.…

Student and Teacher Perceptions of the Use of Multimedia Supported Predict-Observe-Explain Tasks To Probe Understanding.
Peer reviewed Peer reviewed
Kearney, Matthew; Treagust, David F.; Yeo, Shelley; Zadnik, Marjan G. – Research in Science Education, 2001
Discusses student and teacher perceptions of a new development in the use of the predict-observe-explain (POE) strategy. This development involves the incorporation of POE tasks into a multimedia computer program that uses real-life, digital video clips of difficult, expensive, time consuming, or dangerous scenarios as stimuli for these tasks.…

Genetics Reasoning with Multiple External Representations.
Peer reviewed Peer reviewed
Tsui, Chi-Yan; Treagust, David F. – Research in Science Education, 2003
Explores a case study of a class of 10th grade students whose learning of genetics involved activities using BioLogica, a computer program that features multiple external representations (MERs). Findings indicate that the MERs in BioLogica contributed to students' development of genetics reasoning by engendering their motivation and interest but…
