| Abstract: | In this study, we examined how learners developed scientific explanations about light with the assistance of various technology-based
scaffolds. The study emphasis was on scaffolding processes of reflection and articulation. We used a content-neutral software
program (Progress Portfolio) to create the instructional scaffolds. A qualitative research design was used to investigate
two pairs of prospective teachers in a science content course in engineering. Our findings suggested that the computer-based
scaffolds used in our study were useful to support articulation, reflection, and revision of explanations, when certain conditions
were met. A major theme of our findings relates to interacting effects among learner characteristics, teacher coaching, software
scaffolding design, and task characteristics.
