Abstract
The purposes of this reasearch are to investigate (l)the main effects of the " ProcessOriented Writing Teaching Program (POWTP)" on the quality and process of writing,(2)the effects of POWTP on the children of different language abilities, and (3)the progressive effects of the teaching contents and teaching strategies of the POWTP. Thefeasibility of the program for elementary students' writing instruction is also explored. This study adopts the two-factor experimental design. The subjects are 80 fourthgrade students, random selected from an elementary school in Taipei County. Then theyare randomly assigned to the experimental group and the control group. The experimental group receive twelve weeks POWTP and the control group did not receive thespecial training program. Three instruments are used in this study. They are Writing Scaling, Expository Writing Scaling, and Writing Process Interview Scaling. The obtained data are analyzed by two-way ANOVA to test the writing performanceprogress and tansfer effects of the program, and by two-way mixed design ANOVA totest the gradual effect of the program.The findings are as follows:1. The POWTP has positive and optimistical effect. Through POWPT, two writing variables, the quality and process of writing, have got significant difference, but shows no significant transferring effects on the improvement of expository writing.2. There is no interaction between "group" and "ability" on all dependent variables. In terms of the teaching effect of POWTP on the children of different language abilities, the experimental group is better than control group.3. There is interaction between "group" and "assessment stage" on the quality of writing. In the experimental group, the quality of writing would increase gradually with the exposure of POWTP. The results are discussed and there are some suggestions about the program andsuggestions for the future research.
