PENGEMBANGAN TES DIAGNOSTIK BERBASIS KOMPUTER MENGGUNAKAN PROGRAM PHP MySQL PADA MATERI POKOK KESETIMBANGAN KIMIA SMA KELAS XI (DEVELOPMENT OF COMPUTER-BASED DIAGNOSTIC TESTS USING PHP MySQL PROGRAM ON THE SUBJECT MATTER OF CHEMICAL EQUILIBRIUM XI HIGH S

Abstract

Abstrak: Penelitian ini bertujuan untuk mengetahui kelayakan tes diagnostik berbasis komputer menggunakan program PHP MySQL pada materi pokok kesetimbangan kimia SMA kelas XI berdasarkan hasil validitas konstruksi, isi, dan empiris serta mengetahui ketepatan tes diagnostik berbasis komputer yang dikembangkan. Model penelitian yang digunakan merupakan hasil modifikasi antara model 4-D dengan langkah penyusunan pengembangan tes diagnostik yang ditetapkan oleh Departemen Pendidikan Nasional. Hasil penelitian menunjukkan bahwa perangkat tes diagnostik yang dikembangkan telah memenuhi standar kelayakan validitas konstruksi dan isi dengan persentase hasil masing-masing sebesar 96,67% dan 94,50% dinyatakan sangat kuat. Sedangkan perangkat tes diagnostik berbasis komputer juga telah memenuhi standar kelayakan berdasarkan penilaian guru kimia dan penilaian siswa peserta tes dengan persentase masing-masing secara berurutan sebesar 78,79% dan 75,63% dinyatakan layak untuk digunakan di lapangan. Pada uji coba II terhadap 32 siswa ada 4 siswa yang belum tuntas. Siswa yang belum tuntas belajar kemudian didiagnosis sesuai dengan peta tes diagnostik. Dari peta diagnostik dapat terbaca dimana letak kesulitan belajar siswa. Pada penelitian ini dapat disimpulkan bahwa tes diagnostik yang dikembangkan dapat digunakan di lapangan. Pada penelitian berikutnya diharapkan peta diagnostik dapat dimasukkan ke dalam program untuk mempercepat proses diagnosis.

Abstract: The aims of this research are determine the feasibility of computer-based diagnostic tests using MySQL PHP program on the subject matter of chemical equilibrium XI high school class based on the construct validity, content validity, and the concurrent as well as knowing the accuracy of computer-based diagnostic tests are developed. The research model used is a modified version of the model 4-D with the preparation of the development of a diagnostic test measures set by the Ministry of Education. The results showed that computer-based diagnostic tests have been developed to meet eligibility standards of construction and content validity of the percentage of each by 96,67% and 94,50% expressed very strong. While the computer-based diagnostic tests has been meeting the eligibility standard based on valuation and assessment of students' chemistry teacher candidates with the percentage of each sequence of 78,79% and 75,63% declared eligible for use in the field. In the second trial against the 32 students there are 4 students who have not been completed. Students who have not been thoroughly studied and diagnosed according to our diagnostic tests. Diagnostics can be read from a map where the location of students' learning difficulties. In this study we can conclude that the diagnostic tests being developed could be used in the field. In the next study is expected to map the diagnostic can be incorporated into the program to speed up the process of diagnosis.

Key words: diagnostic test, PHP MySQL program.
