The teacher-researcher used both constructivist and traditionalist instructional methods in the sixth and seventh grade mathematics courses. In the sixth grade course, the teacher taught a unit about operations of fractions using an inquiry-based curriculum, Connected Mathematics 2, and the constructivist method, and then taught a unit about basic algebraic operations using a regular mathematics textbook and the traditionalist method. In the seventh grade course, the teacher taught a unit about data and probability using a regular mathematics textbook and the traditionalist method, and then taught a unit about similar figures and ratios using an inquiry-based curriculum, Connected Mathematics 2, and the constructivist method
