Pengembangan modul sistem koloid berbasis pendekatan saintifik dengan pertanyaan probing prompting untuk kelas XI SMA/MA

Abstract

In the 2013 curriculum for all levels of education learnng is using a scientific approach that aims to make student think critical. The research aim to develop a colloid module base on scientific approach for XI SMA/MA class and determine the level of validity and practicality. This developed  module uses probing questions (digging question) and prompting questions ( guiding questions) to train critical thinking students. This research is Research And Development (R&D) with 4-D model. Validity test was done by 3 chemistry lecturers at FMIPA UNP, 2 chemistry teacher at SMAN 1 kayutanam. Practicality test was done by 2 chemistry teacher at SMAN 1 kayutanam and 20 XI IPA 3 SMAN 1 kayutanam students. The instrument was validity and practical questionnaire and data was analyzed by Cohen Kappa Formula. This study produced a colloid module based on scientific approach with an average kappa moment 0.89 which is very high level of validity. The result of the teacher practicality test and the students practicality test obtained an average of kappa moment in a squence of 0.90 and 0.87 with a very high level of practicality.
