LKPD are one of the learning materials that can be used in the learning process. Buffer solution LKPD based on guided discovery learning with three levels chemistry representation. The type of this research was Research and Development (RD) with the 4D development model. 4-D models that consist of four steps: define, design, develop, and disseminate. The research was limited on develop step. The research instrument that used questionnaire in the form of validity and practicality sheet. The LKPD was validated by three UNP chemistry lectures and two chemistry teachers of SMAN 5 Padang. The LKPD was practicalited by two chemistry teachers and 28 students XII MIPA 1 of SMAN 5 Padang. Data were analyzed by Cohen’s Kappa formula. The result of validity test showed that the LKPD had a very high validity category (k= 0,86). Practicality test result showed that the LKPD has very high practicality category ( k= 0,80 dan k=0,82). The LKPD was valid and practical.

This study aims to produce a module ion equilibrium and pH of salt solution and how to categorise module validity and practicality levels. As this is Research and Development study, we used Plomp model consisting three stages, preliminary research, prototyping stage and assessment phase. Guided inquiry is a learning model used in this study. This module is validated by 5 validators with a research instrument in validation and practicality sheet in the form of questionnaires. The validator’s evaluation of each statement was analysed using Kappa Cohen formula. The results show kappa moment value (κ) 0.85 with a very high category. The kappa moment value (κ) for practicality of module based on teacher’s response is 0.88, while student’s response is 0.81. The resulting module is very valid and practical to use.

The development and determination of module validity aims to examine the application of guided discovery learning model to the material reaction rate. The development was carried out using the plomp model with 3 stages, namely preliminary research, prototyping stage and assessment. The stages carried out are only up to the prototyping stage and formative evaluation until the expert review stage. Expert review is carried out through an assessment of 5 validators, namely 3 chemistry lectures and 2 chemistry teachers. Data were collected using a validity questionnaire which was then analysed the Aiken V formula. Based on the results, the resulting module has a valid category with a V value of 0,83 but its practicality has not been tested.
