The purpose of this study is base on Mastery-Learning Theory to
develop one set of Computer-assisted learning software in
mathematics for elementary school, furthermore to discuss the
the efficacy after teaching and to analyse the difficulities
of students in process of learning. An experiment with pretest
-post test nonequivalent-control-group design is conducted.The
subjects are 80 fifth grade students in two classes drawn from
one elementary school. The teaching 4 units of this experiment
are factor,multiple, fraction and plus or minus in fraction in
Mathematics book 9 of elementary school. Based on the results
of statistic analysis from experiments, the important discover
-ies are followed as below: 1. It is an efficient model that
CAL softwares are to be mate- rial in assisted-teaching, based
on Mastery-Learning Theory in mathematics for elementary
school.Producting tool and combi -nating multi-media will be
improved and used. 2. The models in Computer-Assisted
Mastery Learning promote significantly the mastery-member in
teaching units, the effica -cy will be more successively. 3.
The models in Computer-Assisted Mastery-Learning promote
significantly the achievements of students. It is worthy of
applying widely. 4. The models in Computer-Assisted Mastery
Learning help teach -ers to understand students'''' difficulties
in learning process , and to modify the contents of material
in each unit. 5. The models in Computer-Assisted Mastery
Learning supply enough learning-opportunities and help to
realize the ideal of adaptive education. It is worthy of
development. 6. The majority of students appear high learning
positive at- titude in Computer-Assisted Mastery Learning
models.
