This study focuses on how students in different postsecondary mathematics courses perform on domain and range tasks regarding graphs of functions. Students often seem to focus on notable aspects of a graph and fail to see the graph in its entirety. Many students struggled with piecewise functions, especially those involving horizontal segments.…

Through a theoretical framework emphasizing the importance of fidelity of implementation (FOI), this paper explores how 3rd and 4th grade teachers implemented an early algebra intervention, and the extent to which the FOI related to student learning. The data for this report are taken from the first two years of an experimental research project.…

Instructional strategies make a difference in whether students are engaged in learning and are profiting from their time in class. High schools, technology centers and middle grades schools are encouraging teachers to adopt new teaching techniques and are providing opportunities for teachers to work together to improve their instructional skills…

Students in a college introductory statistics class were evaluated with conceptual and computational tests and the relationship between their levels of knowledge on the two forms of testing was assessed. There were significant correlations between their abilities to perform computations and to answer more conceptual questions on individual tests…
