摘要：Controlling complexity through the use of ions is a critical part of problem solving in programming. Thus, becoming proficient with procedural and data ion through the use of user-defined functions is important. Properly using functions for ion involves a number of other core concepts, such as parameter passing, scope and references, which are known to be difficult. Therefore, this paper aims to study students’ proficiency with these core concepts, and students’ ability to apply procedural and data ion to solve problems. We collected data from two years of an introductory Python course, both from a questionnaire and from two lab assignments. The data shows that students had difficulties with the core concepts, and a number of issues solving problems with ion. We also investigate the impact of using a visualization tool when teaching the core concepts.
