Most of the students had difficultyin understanding the concept of chemistry which is abstract and cannot connect the concepts studied with the phenomena in everyday life.This is because the instructional media and learning models used by the teacher do not pay attention to submicroscopic representations and do not link chemistry with the environment around students.This study aims to develop Chemical Interactive Multimedia (CIM) based on PBL (Problem Based Learning) to improve students' Generic Science Skills (GSS). PBL-based CIM was developed on the concept of salt hydrolysis in a tutorial format. This study was a Research and Development using the ADDIE design. The research procedure consists of five stages, namely Analyze, Design, Development, Implementation, and Evaluation. The PBL-based CIM effectiveness test against the GSS of MA Darul Habibi NW Paok Tawah students was carried out at the implementation stage using a one-group pretest-posttest design. The instrument used was in the form of a questionnaire to obtain eligibility data and student responses, as well as a description test to obtain KGS data. CIM based on PBL feasibility data will be analyzed using a five-scale absolute norm, student responses were analyzed descriptively, and GSS data were analyzed using a normalized gain score (N-gain). The validation results show that PBL-based MIK has an average score of 92% which means it was very feasible.The limited trial of 12 students stated that PBL-based CIM met the aspects of appearance, readability, language, and ease of use very well.The results of PBL-based CIM trials in learning can increase students' GSS which is indicated by an average N-gain score of 58% in the moderate category.Therefore, it can be concluded that PBL-based MIK was successfully developed in the very feasible category and could improve students' GSS.

One of the chemistry conceptsthat was considered difficult by students was acid-base concept. Acid-base conceptwas closely related to everyday life and includes three representations of chemical levels, namely: macroscopic level, microscopic level and symbolic level, so students experience difficulty in learning it. The development of a teaching material in the form of LKS was seen as a solution to this problem. This study aimed to develop teaching materials in the form of POE LKS oriented to green chemistry to foster students' scientific attitudes towards acid-base concepts. This studywas development research with ADDIE (Analysis, Design, Development, Implementation, and Evaluation)model design. Quantitative data from the results of feasibility validation and the results of assessment of scientific attitudes of students were analyzed by percentage formula and the results of student responses were calculated using N-gain. Qualitative data in the form of responses and suggestions for improvement from the validator. The validator's assessment of the results of the development obtained an average percentage of 83.2%, 84%, 81.6%, and 78.93%. While the responses of students were analyzed using the N-gain test obtained an average score of 0.4 with a moderate category and students' scientific attitude data obtained an average score of 61% with moderate qualifications.

Chemistry investigates interactions and reactions of particles as atom, ion, molecule, and their tendencies. Interactions occurred are so abstract that make them become difficult to be observed and documented. This becomes a problem in learning chemistry. It happens due to the separation of macroscopic and microscopic concepts. In fact, to be able to obtain the concept of chemistry as whole requires learning model which can integrate three aspects namely macroscopic, symbolic-conducted through practicum, and microscopic-conducted through modeling interactive media. This study aimed to developed interactive learning media for fundamental chemistry class. This study belongs to Educational Research and Development. In general, there were three steps conducted by the researcher namely analyzing, designing, and developing.
