Employing Context-Based Learning to Bolster Conceptual Understanding of Gas Law Relationships in General Chemistry ()
ABSTRACT
The subject of gas laws is regularly taught as part of the general
chemistry curriculum in college. In this study, there is an examination of the
effectiveness of a 45-minute
in-class based intervention using a series of four short vignettes of contexts
students are likely to be familiar with to help improve students’ conceptual understanding of the relationships between
different properties of gases. The study was completed over a 3-year
period involving a total of 352 students. In each year, there was one intervention class and one control
class in which performance on identical gas law assessment items was compared. In particular,
this intervention was designed such that it could fit smoothly into a
traditionally lecture based general chemistry course without requiring major
shifts in overall course design in order to make it more attractive to faculty
who might be resistant to a major overhaul of their general chemistry course.
When compared with the control class not containing the intervention, students in the intervention course were found to have
performed significantly better on assessment items related to how gases
behaved when not supplied with numerical data (p < .001).
