Experiment l Subjects – – students taking the course of CS 2604 Three groups using different tools: Text, Inset and Binary Treesome
Experiment (Contd. ) l Procedure – – – Introduction, consent form and demographic form (5 minutes) Learning AVL tree using one of tools (15 minutes) Quiz and post survey form (15 minutes)
Experiment (Contd. ) l Tasks and Materials – – l Consent form and demographic form Text material and two visualization tools: inset and binary tree Question-answering tasks: conceptual questions and procedural questions Post session survey Dependent Measures – – Students’ performance Students’ satisfaction
Results l Means Scores :
Analysis l l ANOVA T - test See Data
