The objective of this paper was to study and development of rice straw paper and development of rice straw paper products-making. Part I. Rice straw paper-making. The bleached and unbleached with 2% HP2(aqJform rice straw fiber was boiled with 2% and 4% NaOH(aq) The 4 treatment was take out container and spread in to thin piece of paper. The 4 treatment were conducted to test physical properties and strength properties on rice straw paper. Part II Rice straw paper products-making. The populations in this research were 16 students and 16 teachers on RIT. Chotiwet Campus to making and evaluate the rice straw paper products. The instrument used in this research were questionnaires about the admission on specifics properties of rice straw paper products and satisfaction to rice straw paper products. The data were analyzed by SPSS program. The statistic used that mean standard deviation one way ANOVA and two way ANOVA. Differences between various groups were tested by Scheffs method.

The reliability was 0.85. The data were analyzed by using the computer program SPSS for window. The statistics analysis includes a -coefficients percentage mean and standard deviation The results were as follows : 1. Most students occupied collaborative and participant learning styles then independent dependent avoidance and competitive respectively. 2. The competitive and collaborative affecting learning achievement were significantly different at P<05. The competitive learning style has the negative affecting towards learning achievement. The Collaborative learning style has the positive affecting towards learning achievement. 3. The equation used for predicting learning achievement is Y = 2.697 -0.118 X6 +0.158 Xs
