摘要:Web Based Learning Model provides various opportunities for students to study individually without time and space limitations and makes positive effects on students’ learning and success. However, totally on-line courses have some limitations. To overcome these limitations, educational experts offer a mixture of traditional and on-line education together, called the hybrid model which can be superior to both traditional classes and totally on-line courses in terms of students’ success. In this study, the effects of the “Hybrid Model” on the students’ success related to chemistry subjects in the primary school 7th, 8th year science teaching program, in Turkey, by mixing two hours traditional teaching followed by a one hour on-line application by using a web page specifically designed for this study. As a result of this study it was found out that the hybrid model, when compared to the traditional learning method, has created positive effects on students’ knowledge gain and success.
