The 5E instructional model is known for increasing student engagement and participation in the learning process. While viewing the video recorded lessons of middle school mathematics teachers, the researchers noticed teachers had a difficult time implementing the 5E model with fidelity. This case study explored the extent to which mathematics…

Planning a mathematics lesson plan is a complex process. Its quality contributes to the effectiveness of mathematics instruction. Given this significance, improving prospective mathematics teachers' lesson planning ability is essential for teacher preparation programs to produce effective teachers. This study examines how a lesson study within a…

As part of an NSF funded project we developed new course materials for a general introductory statistics course designed to engage students in statistical discovery. The materials were designed to actively involve students in the design and implementation of data collection and the analysis and interpretation of the resulting data. Our overall…
