Abstract

Exploring Undergraduate Students’ Computational Literacy in the Context of Problem SolvingBackgroundComputational Science and Engineering (CSE) is a modern practice in workplace engineeringused to solve complex problems in disciplinary areas using computational tools1. In educationalsettings, there has been a call to integrate computational tools and methods into the differentdisciplinary engineering curricula sooner and often2. In Materials Science and Engineering, a subdiscipline has been established called Computational Materials Science3. Attending this call, thedepartment of Materials Science and Engineering at a Mid-Atlantic University started acurricular innovation consisting of one computational course for material scientists (CPMSE)and the integration of several computational modules into subsequent six core courses.This study focuses on understanding how computational tools and methods were applied duringthe problem solving episodes to support the solution of computational challenges in a freshmencourse. The research questions addressed in this study are: ● How does students’ performance in solving computational challenges relate to their disciplinary learning outcomes in a computational material science course? ● How do specific steps of the problem solving process relate to student overall performance in a computational materials science course? ● How does students’ problem solving approaches relate to students’ programming skills?MethodsThe CPMSE course was designed using the How People Learn framework4. Hence, it isKnowledge Centered, Learner Centered, and Community Centered. It uses MATLAB as theprogramming environment and the learning objectives are5: (1) Write MATLAB programs to execute well-defined algorithms. (2) Design algorithms to solve engineering problems by breaking these into small tractable parts. (3) Model physical and biological systems by applying linear systems and ordinary and partial differential equationsThe course employs an inverted classroom approach where students are required to watch therecorded lectures before coming to class for practice exercises. During the semester, the studentsare required to complete five computational projects related to their core courses. The projectswere organized using the four steps problem solving process6: (1) Understand the Problem; (2)Devise a Plan; (3) Carry out the Plan; and (4) Review/Extend. The disciplinary andcomputational learning outcomes for each of the projects are described in Appendix A.Twenty three freshmen and sophomore material science and engineering students enrolled in theCPMSE course in spring 2014 participated in the study. The participants solved fivecomputational projects following the four problem solving steps. The projects were evaluatedusing an assessment rubric presented in Appendix B. The rubric has three major components: (1)Problem Solving Steps; (2) Disciplinary Outcomes; and (3) Computational Literacy. Theseindividual components and each rubric criteria were first analyzed using descriptive statistics.Afterwards, the three components were correlated among each other and to project scores, andcourse score. This process was carried out for the individual projects and for the averageperformance in each of the rubric criteria.ResultsTable 1 depicts average scores for all projects grouped by the three different criteria. The highestscores were obtained in the computational literacy skills constructs for all the projects but projectone. This result suggests that students took some time to acquire these skills, but they were ableto use them in different disciplinary contexts. Table 1.

Results suggest that in average, problem solving is closely related to the computationalliteracy skills. These two constructs are also determinants for the total projects scores and for the coursescore. Table 3.

Preliminary analysis suggests that students maybe able to acquire and maintain computational literacy skills throughout a computationaldisciplinary course. Another relevant result suggests that there is a close relationship betweenadequately following the problem solving steps and writing an organized program that executescorrectly.References1 Turner, P., Petzold, L., Shiflet, A., Vakalis, I., Jordan, K., & St. John, S.
