Design and assessment of an algorithm learning tool for high school computer science

This paper presents an algorithm learning tool developed for a computer science class in a science and technology high school in Japan. The learning tool offers features specifically designed for novice learners. It presents lessons and animations that aim to facilitate teaching and learning of four fundamental algorithms. The animations were based on the concept of Algorithm Visualization. Pre and posttests, questionnaires on motivation, and a software usability questionnaire were designed and implemented as evaluation instruments. Initial results show that the learning performance of students increased after using the algorithm learning tool. Evaluation of the tool demonstrates positive acceptance by the students. Results also show that a number of features of the learning tool contribute to the increase understanding of algorithms among the students.
