Development of Electrolyte and Nonelectrolyte solution Module Based on Science Approach to Science Prompting Probing Technology Class X SMA / MA

This study aims to produce electrolyte and non electrolyte solution modules based on a scientific approach with probing prompting techniques and determine the level of validity, practicality and effectiveness of the module. This research includes development research using the Plomp development model which has three stages, namely the initial investigation phase (preliminary research phase), the prototype phase (prototyping phase) and the assessment phase. At the prototyping stage, self evaluation is carried out, expert review, one-to-one evaluation, small group evaluation, while the assessment phase is carried out through field tests. in 2 schools namely SMAN 1 Shadow and SMAN 1 Koto XI Tarusan. The research instrument used was a questionnaire in the form of validity and practicality sheets and a matter of objective forms. The results of practicality by students in small groups and in the field test are very high and the level of practicality by the teacher is also very high. Hypothesis test results showed a significant difference between the learning outcomes of the experimental and control classes in schools with high student ability, while there were no significant differences in schools with low student ability.
