There is a longstanding debate on whether the analysis of covariance (ANCOVA) or the change score approach is more appropriate when analyzing non-experimental longitudinal data. In this article, we use a structural modeling perspective to clarify that the ANCOVA approach is based on the assumption that all relevant covariates are measured (i.e.,…

The randomized control trial (RCT) is the primary experimental design in education research due to its strong internal validity for causal inference. However, in situations where RCTs are not feasible or ethical, quasi-experiments are alternatives to establish causal inference. This paper serves as an introduction to several quasi-experimental…

A computational experiment investigating common organic chemistry mechanisms has been developed and implemented in a junior/senior-level physical chemistry laboratory course at two institutions. Students investigated various reactions that proceed via S[subscript N]1, S[subscript N]2, E1, and E2 mechanisms using hybrid Density Functional Theory…

In today's educational climate, physical education teachers are required to assess student learning in order to document student growth and demonstrate effectiveness as a teacher. However, because many schools limit the amount of time students spend in physical education, it is often difficult to assess student learning without it interfering with…

"Cha-Ching" is an interactive learning game that introduces 7- to 10-year-olds to fundamental financial concepts and fosters family dialogue about financial decisions. The authors found that the game was engaging for eight- and…

This chapter describes a service learning (SL) project implemented in an upper-level undergraduate "Cost Accounting" course to enhance the coverage of costing concepts. Employing a variation of Lafond, Leauby, and Wentzel (2017) SL task, students actively gather cost data for a business venture by preparing peanut butter and jelly…

This project produced an online astronomy course based on the free, online OpenStax textbook. When this project was conceived, about a year before the COVID-19 pandemic, the authors had no idea that in a short period of time, most college and university classes would be online. This abrupt change in modalities of courses, from traditional,…
