- W3083693917 abstract "This research was conducted to find out:1) the feasibility level of problem based virtual laboratory media of ecosystem sub topic (biogeochemical cycle) according to materialexperts media design experts, instructional media experts, virtual technology experts, 2) the feasibility level of media according to students and teachers responses, 3) to know the improvement of student’s science process skills after using problem based virtual laboratory media of biogeochemical cycle in learning process in senior high school. Based on the results of the validation of material experts, media design experts, instructional design experts and virtual technology experts the results were very good, the percentage values were 95% 85.5%, 85%, 90.62% respectively. Student’s responses on media from individual trial, small group trial and limited group trial showed that virtual media developed was also very good, with average scores 91%, 90.25%, 92%, respectively. Teacher’s responses on media from individual trial, small group trial and limited group trial were very good too with averagescores 79%, 92%, 91%, respectively. In conclusion, the media developed was considered very good and feasible to use as learning media. Effectiveness of media was found out bycarrying out pseudo-quasi experiment on first grade students in senior high school SMAN 1 Lubuk Pakam. Two classes were taken by cluster random sampling method as sample, XMIPA 1 as experiment class and X MIPA 4 as control class. Research result showed that student’s science process skills score that be thought by problem based virtual laboratorymedia was significantly higher or better than class without virtual laboratory media ( tcount = (3.62) > ttable = (1.67) at α = 0.05)." @default.
