Abstract

This research is aimed to know the procedure and product quality of the development of a problem based instructional materials for operating the computer operating system at grade X TEI of SMK Negeri 2 Lamongan.

Subjects for readability test, simulation and field test were students at grade X TEI of SMK Negeri 2 Lamongan, First Semester, Academic Year of 2012/2013. The details were as follows: 30 students for field test, 6 students for simulation, and 3 students for readability test.

The research method was research and development. The development model of the instructional materials was Sugiyono’s Product Development Model (R&D) which had been modified. The methods of data collection were test, observation, questionnaire, and documentation. The instrument of data collection that used in the research were the validation sheets of instructional materials consist of lesson plan (RPP), student’s worksheet (LKS), final test (THB), the observation sheets of teacher model’s ability in managing the instructional activity, the observation sheets of student’s activity and the questionnaire sheets for students’ responses and the  final test.

Based on analysis result of validation, readability test, simulation and field test, obtained that the Problem Based Instructional materials for operating the computer operating system that developed were good quality, because it had been declared valid by media expert, material expert and practitioner/teacher for the RPP with average score of 4.01 categorized as good, for LKS with average score of 4.00 categorized as good, for THB with average score of 3.17 categorized as good and satisfied to the conditions: 1) the ability of teacher in managing the instruction was effective/good with average score 4.13, 2) student’s instructional activity duration was effective with tolerance 10%, 3) students had good and positive responses with 90.62%, answered Yes, 4) final test: a) validity of final test items that caculated with product moment corelation formula with r_tabel (30; 5%) had minimally moderate category. b) the reliability of final test was in the very high category with a Cronbach Alpha coefficient of 0.97, c) all test items were good/sensitive to learning.
