Abstract
This paper is aimed to design and to implement a new inquiry based laboratory model and cookbook experiment model on a simple concave eyeglasses experiment in Indonesia. The model is a part of experiment models contributing to developing standardization of national experiment examination through revised 2013 curriculum framework. The model has been successfully applied to K-11 in a Private Senior High School. The best achievement of the model is very high with (0.92) item validity as much as its reliability, good (0.50) discrimination power, and medium (0.64) difficulty index. Average student can achieve 72% of experiment process test including finding problems, tools, method, procedure, data, analysis, and conclusion. We concluded that several competences can be trained by using inquiry based laboratory experiment, including understanding experimental problem, determining experimental tools needed, choosing an appropriate method, composing the experiment procedure, collecting data, analyzing data, and writing conclusion.
