    Learning multiplication through computer-assisted learning activities
    (Elsevier, 2008-09-01) Chang, Kuo-En; Sung, Yao-Ting; Chen, Yu-Lung; Huang, Long-Hua
    This study develops and implements a computer-assisted learning (CAL) program with both multiplicative facts practices and the instruction of meaning behind these facts. The effectiveness of CAL on the development of multiplication abilities is also explored. Eight CAL activities are developed to teach multiplication to second grade elementary school students. The CAL program is comprised of three stages of instruction that addressed in succession the basic concept of multiplication, the meaning and properties of multiplication and multiplication-related computation skills. Evaluation of the effects of the learning activities reveals that CAL activities are effective in improving comprehension of the concept of multiplication and the meaning and properties of multiplication for students who have lower prior knowledge of multiplication, but it does not significantly improve the development of multiplication-related computation skills. Nevertheless, CAL activities facilitate overall learning of multiplication.

    Developing geometry thinking through multimedia learning activities
    (Elsevier, 2007-09-01) Chang, Kuo-En; Sung, Yao-Ting; Lin, Song-Ying
    In this study, a multimedia learning software program named GeoCAL is described. It is based on van Hiele’s geometric thinking level theory, which consists of four levels: recognition, visual association, description/analysis, and abstraction/relation. In addition to presenting the software design, this study also explores the learning effects of GeoCAL on each of the geometric thinking levels and on overall geometric thinking. The subjects of this study are second-grade elementary school students of an average age of eight who have not previously had formal lessons in geometry. The experimental results indicate that, with the exception of recognition ability, GeoCAL produces significant learning effects on visual association, description/analysis and abstraction/relation as well as overall geometric thinking.
