Improvement and Evaluation of a Block-based Language Environment for Introductory C# Programming Course

This research improved and evaluated a blockbased tool for teaching novices introductory C# programming. The hybrid approach of teaching C# was applied in the study. Consequently, a novice-oriented application, called CSBlock, was developed based on Blockly. Participants enrolled in a four-week online C# course to verify its effectiveness in teaching settings. After the course, participants completed four tasks using C# and submitted a final questionnaire. By analyzing the tasks and questionnaires submitted by the participants, the study found that CSBlock did not improve participants' learning effect and performance, specifically even performed worse in loop statements.
