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%.","PeriodicalId":212381,"journal":{"name":"Proceedings of the Proceedings of the First International Conference on Science, Technology and Multicultural Education, ICOCIT-MUDA, July 25th-26th, 2019, Sorong, Indonesia","volume":"53 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141206236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach used in this study is a qualitative approach with research subjects in class VIII students of MTs Muhammadiyah Aimas Kab. Sorong. The research subjects are three students who have been selected based on their problem solving abilities which are categorized as one student with high ability, one student with medium ability and one student with low ability. Data obtained through interviews and three problem solving of geometry. The validity test used was the validity of the questions from the three questions each showed 0.817; 0.813 and 0.677 this means that the three items are feasible to use, while for the reliability test shows 0.784 it shows that the problem solving ability test is included in the high category. The results of research that have been done show that students who are highly capable can understand the problem, able to make the planning stage, able to solve the problem with the right steps, and able to check answers. Students who are capable are able to understand the problem, able to plan, able to solve the problem, but are unable to check the answers again. Then for low-ability students who have not been able to understand the problem, have not been able to plan, are still unable to solve the problem and are unable to check again.","PeriodicalId":212381,"journal":{"name":"Proceedings of the Proceedings of the First International Conference on Science, Technology and Multicultural Education, ICOCIT-MUDA, July 25th-26th, 2019, Sorong, Indonesia","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122350906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
