In this study, the effects of blended learning on the middle school students' academic achievement level and product evaluation scores were investigated. Blended learning provides more effective learning outcome gains through enriching todays' developing Web Technologies with learning environments. This study was carried out with a total of 53 students enrolled in the experimental group and control group in the 6 th grade classrooms during the 2014/2015 school year in a middle school in southwest part of Turkey. The intervention lasted 7 weeks. During the seven weeks, the unit of "problem solving, computer programming and development of Software product", covered in Educational technologies and Software course, is taught through blended learning environment. The experimental group was taught using blended learning environment which supported with enriched web technologies (such as video-conference, Learning Management System, Discussion blogs, etc.). Whereas the experimental group was given access to all these enriched contents that are presented to the control group only during the classroom environment through present teaching methods.The design of the study includes quantitative method. We collected quantitative data such as academic achievement test and product evaluation scale. Academic achievement test and product evaluation scale were used as quantitative data collection sources. Quantitative data was collected through the evaluation of students' projects that they developed during the process of the study and the academic achievement tests. During the data analysis phase, independent t-test, frequency and ANOVA tests were used. As a result of this study, it is concluded that blended learning environment had generated a significant difference in students' academic achievement on behalf of experimental group. Implications of the study for the educational environments were discussed.
