Retrospective Theses and Dissertations

Many students encounter difficulties engaging with laboratory-based instruction, and reviews of research have indicated that the value of such instruction is not clearly evident. Traditional forms of writing associated with laboratory activities are commonly in a style used by professional scientists to communicate developed explanations. Students probably lack the interpretative skills of a professional, and writing in this style may not support students in learning how to develop scientific explanations. The Science Writing Heuristic (SWH) is an inquiry-based approach to laboratory instruction designed in part to promote student ability in developing such explanations. However, there is not a convincing body ...

Teacher-Child Verbal Interactions In Preschool Science Teaching , Tsung-Hui Tu

Retrospective Theses and Dissertations

The purpose of this study was to examine preschool teachers' verbal interactions with children during morning self-selection time. Naturalistic (Day 1) and experimental (Day 2) designs were used to provide empirical evidence of the availability of science activities and accessible science materials in preschool classrooms. The participants were 20 head teachers of 3- to 5-year-old preschoolers employed in central Iowa child care centers. Each teacher was videotaped for two consecutive days during morning self-selection time. The most frequent preschool teachers' verbal interaction for Day 1 and Day 2 combined was giving learning guidance, and they used more verbal statements than ...
