Research indicates there is a need for teachers to experience multiple mastery experiences with engineering teaching in order to improve teaching engineering self-efficacy. To prepare future K-5 teachers to teach the engineering design process, one science methods course integrated 2-day engineering mini-units into the class meeting and…

In this exploratory study, we examined the effects of a quantitative reasoning instructional approach to linear equations in two variables on community college students' conceptual understanding, procedural fluency, and reasoning ability. This was done in comparison to the use of a traditional procedural approach for instruction on the same topic.…
