Development of Blended Learning Model with Virtual Science Laboratory for Secondary Students

This study is conducted in terms of research and development aiming for developing blended learning model using project-based learning via virtual science laboratory in a science classroom for students in secondary schools. The model could lead students to understand sciences lessons easier and enable to do experiments in lesser time, and encourage them to create new further experiments with curiosity. In addition, the model combines face-to-face learning and learning on online network to optimize the advantages of both methods. The research process is divided into 2 phases: 1) the development of blended learning model using project-based learning via virtual science laboratory, and 2) the affirmation of blended learning model using project-based learning via virtual science laboratory. The research samples are five experts selected by purposive sampling. The research instruments are the model of blended learning model using project-based learning via virtual science laboratory, and the evaluation of the model's appropriateness analyzed by means and standardized deviations statistically. The research result shows that: 1. There are five modules in the model which are 1) Student Module 2) Instructor Module 3) Blended Learning Module from Project-Based Learning and Active learning for students to conducting science projects and to check how much they understand what they have learned 4) Virtual Laboratory Module and 5) Assessment Module. 2. The five experts assessed the instruction model, and pointed out that the developed instruction model is highly appropriate. This shows that the developed instruction model can be used for enhancing analytical thinking skills and evaluation of ability in conducting science projects for secondary students.
