Engaging students in scientific practices has become an important pedagogical component in STEM education, although its implementation in laboratories is still emerging. This paper uses three types of guiding questions to facilitate scientific practices in introductory and analytical chemistry laboratories. What makes our instructional model…

Effective teachers understand the importance of asking the right kind of questions to facilitate the learning of all their students. By learning what questions to ask and when, teachers can engage their students in instruction that aligns to the vision of the "Next Generation Science Standards" (Benedict-Chambers et al. 2017; NGSS Lead…

Guiding students to generate testable scientific questions is essential in the inquiry classroom, but it is not easy. The purpose of the BDC ("Big Idea, Divergent Thinking, and Convergent Thinking") instructional model is to to scaffold students' inquiry learning. We illustrate the use of this model with an example lesson, designed…

Presents a learning model for science education and describes teacher interventions derived from the model to produce cognitive restructuring. Demonstrates how teacher interventions may be developed through a series of interventions, related activities, and comments. (MDH)
