This research proposes the development of a web-based assessment system to identify students' misconception. The system, named WAS (web-based assessment system), can identify students' misconception profile on linear kinematics automatically after the student has finished the test. The test instrument was developed and validated. Items were constructed and arranged from the result of a focus group discussion (FGD), related to previous research. Fifty eight students (female = 37, male = 21) were used as samples. They were from different classes with 18 students from the gifted class and another 40 students from the normal class. WAS was designed specifically to support the teacher as an efficient replacement for a paper-based test system. In addition, WAS offers flexible timing functionally, stand-alone subject module, robustness and scalability. The entire WAS program and interface was developed with open source-based technologies such as the XAMP server, MySQL database, Javascript and PHP. It provides results immediately and provides diagrammatic questions as well as scientific symbols. It is feasible to apply this system to many students at once. Thus, it could be integrated in many schools as part of physics courses.

Abstrak: Penelitian ini bertujuan untuk mengembangkan instrumen Tes Diagnostik Miskonsepsi Empat Tahap Tentang Kinematika (TDMET-K) yang dapat mendeskripsikan profil miskonsepsi guru fisika SMA dengan kriteria baik. Penelitian menggunakan metode penelitian & pengembangan dengan guru fisika SMA di Surakarta sebagai subjek penelitian. Tahapan penelitian terdiri atas kajian literatur untuk menyusun draf awal; uji validitas secara kualitatif oleh dua ahli; uji validitas isi secara kuantitatif menggunakan formula Lawshe; uji coba lapangan awal (6 subjek); uji coba lapangan utama (30 subjek) sebagai bahan untuk menguji reliabilitas menggunakan formula Alpha Cronbach. Hasil uji menjadi bahan revisi sehingga dihasilkan TDMET-K final. Instrumen pengambilan data yang digunakan berupa angket. Analisis data dilakukan secara kuantitatif dan deskriptif kualitatif. Hasil uji kuantitatif menunjukkan bahwa baik item maupun instrumen memenuhi kriteria validitas isi yang baik dan reliabilitas instrumen termasuk kategori tinggi. Penelitian ini telah berhasil mengembangkan instrumen TDMET-K sebanyak 30 butir yang dapat mendeskripsikan profil miskonsepsi guru fisika SMAdengan kriteria baik.

This research and development study involved high school physics teachers in Surakarta as the research subjects. The research was conducted in the following stages: literature review to prepare initial draft; qualitative test of validity by two experts; a quantitative test of the content validity using the Lawshe formula; an initial field trial (6 subjects); and a main field trial (30 subjects) to explorethe reliability of the test using the Cronbach Alpha formula. The result from the try out was subsequently revised to create the final product.A questionnaire was used to collect the data. Both quantitative and qualitative descriptive analyses were performed.The quantitative test results indicated that both the items and instruments meet the criteria of good content validity and high reliability. This research has developed an instrument consisting of 30 items that can be used to describe high school physics teacher's misconception.

Abstract. The research aims to develop Problem Based Learning material teaching of Mathematics Physics and to know the effect on the cognitive capability of undergraduate students. The research uses development method of Borg and Gall. There are ten steps such as data collection, planning, product drafting, pretest, pretest revise 1, main test, main test revise 2, posttest, final revision, and dissemination and implementation. The data collection uses questionnaire and cognitive test which will support the qualitative data. The result shows that the criterion of developing problem-based learning teaching materials is 5 level category when 43.33% respondents rate 5 level category and the others give 4 level category. Furthermore, students which use the materials increased and the most of the students have acquired cognitive value exceeds the value of minimum completeness criteria.
