VIRTUAL LABORATORY DEVELOPMENT AS ICT BASED LEARNING MEDIA IN ACID AND BASIC TITRATION LEARNING

. This study used the Research and Development (R & D) method. In this case, the development of a Virtual Laboratory with a Dick & Carey model that is consisted of 10 components which are limited to the formative evaluation stage. The stage consists of the expert judgment stage, small group try out, and field try out to produce an ICT-based teaching material in the form of a Virtual Laboratory on Acid Base Titration learning that is valid, practical and effective. To achieve this goal, this study will be carried out in 1 (one) year starting from the preliminary study then continued with the preparation of a draft of ICT-based learning media in the form of Virtual Laboratory learning media. This draft was validated and trialed on a small scale field, analyzed, and revised. The draft revised on a small-scale trial is then tested on a large scale, revised and refined to produce the quality learning media. The stages of validation are carried out theoretically and empirically along with the expert. The result of this study indicated that the Virtual Laboratory learning media that was developed is suitable to be used as ICT-based learning media in the Acid Base Titration material which is marked by the results of media expert evaluations with the criteria of "good" and by material experts with the criteria of "very good". The Virtual Laboratory that was developed also has an acceptability level with the criteria of the students’ responses and lecturers which is "very supportive" and supported by the evaluation data on the average completeness of students (grades A and B) of 87.5%.
