Abstract

The Effect of Inquiry-Based Activities and Prior Knowledge on Undergraduates’ Understanding of ReversibilityThis NSF funded (DUE 0717536) study investigates the role of prior knowledge and the use ofinquiry-based activities and their method of implementation to reduce misconceptions in five keyareas of thermodynamics (Entropy, Reversibility, Equilibrium and Steady State, Internal Energy,and Enthalpy), with a more detailed focus on reversibility. There is documented evidence ofproblems understanding heat, temperature, and energy concepts. Even after instruction,undergraduate engineering students have been found to still hold misconceptions aboutthermodynamic concepts. Previous research has shown that it is difficult to repair thesemisconceptions using a lecture-based pedagogy. One promising approach is the use of inquiry-based activities however; the way these activities are implemented can impact outcomes andprevious research has shown that faculty does not always implement activities as they areinstructed. The prior knowledge students bring to the classroom can also represent a challengewhen trying to alter these misconceptions. It would be anticipated from research that studentswith some prior knowledge from other engineering courses should have a better understanding ofthermodynamic concepts.A quasi-experimental design was used to analyze pre-post data from 26 different undergraduate,thermodynamics classes from multiple institutions, some who used a series of inquiry-basedactivities in each key concept area as part of their instruction and some who did not. Those usingthe inquiry-based activities were given a set of two activities along with worksheets andexplanatory materials for each of the five concept areas where misconceptions had previouslybeen identified, including reversibility. The Concept Inventory for EngineeringThermodynamics (CIET) and its Reversibility sub-test were used to measure conceptual change.Both have been found to have sufficiently high estimates of internal consistency reliability to beused for research purposes. Data was also collected on whether students had previously takenfluid dynamics and heat transfer courses. Finally, instructors were asked to indicate how theyhad implemented a packet of inquiry-based activities specifically designed to teach reversibility.Results showed that conceptual understanding of thermodynamics (five concept areas) asmeasured on the CIET was significantly higher for the inquiry-based activities groups than theno inquiry-based (control) groups, although the effect size was small. Post-test scores weresignificantly higher for students who had previously taken courses in fluid dynamics and heattransfer when compared to those who had not. There was a significant difference between theinquiry-based and control groups on students’ understanding of reversibility and theirunderstanding of this concept area was impacted by their having taken fluid dynamics and heattransfer. The way in which the professors implemented the reversibility activities was collectedand evaluated.
