According to this explicit way of teaching scientific explanation, a framework is needed for scaffolding students' progression towards the competence of scientific explanations.
The teacher's assistance is required in scaffolding students' learning, transforming their questions into research questions that are appropriate for authentic scientific inquiry (Wayne Allison and Shrigley 1986).
Forums and wikis could have complementary functions and should be organized to complete each other for scaffolding students' self-regulated strategies and learning.
A key element of AutoTutor's effectiveness is that it emulates how human tutors work with students, which revolves around scaffolding students to self-explain key expectations required to solve a problem (Graesser et al. 2012).
This project was done individually and, in order to provide further scaffolding, students were required to submit their data set and project plan for approval before completing the project.
For example, Simons and Klein (2007) examined the impact of scaffolding and student achievement levels in a PBL environment, whereby students were subjected to different scaffolding conditions.
Tutors are expected to play active roles in the scaffolding of student learning in a PBL curriculum by providing a framework that students can use to construct knowledge on their own (De Grave et al. 1999).
