Validitas dan Praktikalitas Modul Larutan Penyangga Berbasis Pendekatan Saintifik dengan Menerapkan Teknik Probing dan Promting untuk Kelas XI SMA/ MA

Sari

Curriculum 2013 recommends scientific approach in learning and expects students
to be critical thinking. The research aim to develop a buffer module based on scientific
approach for XI SMA/ MA class and to determine validity and practicality level. This
developed module uses probing questions (digging questions) and promting (guiding
questions) to train critical thinking students. This research is Research and Development
(R&D) with 4-D model. Validity test was done by 2 chemistry lecturers at FMIPA UNP, 1
chemistry teacher at SMAN 7 Padang, 1 chemistry teachers at SMAN 12 Padang and 1
chemistry teacher at SMAN 13 Padang. Practicality test was done by 2 chemistry
teachers at SMAN 7 Padang, 1 chemistry teacher at SMAN 13 Padang and 27 XII MIPA
5 SMAN 7 Padang students. The instrument was validity and practical questionnaire and
data was analyzed by Cohen Kappa formula. This study produced a buffer module based
on scientific approach with an average kappa moments 0,94 which is very high level of
validity. The results of the teacher practicality test and the students practicality test
obtained an average of kappa moments in a sequence of 0,91 and 0,73 with a very high
level and high level of practicality
