General chemistry is a subject that being studied in almost every science course. The subject is closely related to the environment, so it will be very easy to learn when involve examples in everyday life. The Contextual Teaching and Learning (CTL) approach is an approach that links the learning materials with the real-world environment. This research was conducted by using a CTL approach in a general chemistry subject which is one of the compulsory subjects in Biology Education Program of Tarbiyah Faculty UIN Ar-Raniry. The aim of this study was to determine the increase of student learning activities after using the CTL approach to general chemistry lecturing activities. The design of this study used action classroom research. This study was conducted to the first semester students. The student amount was 31 students. The instrument used was an observation sheet of learning activity. The results was obtained that the activities of the student during the learning process in the first cycle reached 70% and increased to 90% in cycle II. This proves that the application of CTL approach can increase the learning studentâ€™s activity of Biology Education Studies in general chemistry courses.

Research on the development of virtual books on geometri molecular form materials at MAS Ulumuddin Lhokseumawe, was motivated by the limited use of instructional media in learning process. The learning media used are reading books and LKPD, chemistry learning is also often considered difficult because generally the geometry molecular material is abstract and requires high imagination to understand it. Virtual books are media with animation in the form of software that can be accessed or opened via computers and laptops. The media is equipped with covers, instructions user, concept maps, materials, 3D molecular shapes and quizzes. The purpose of this study was to determine the development of a virtual book on molecular form materials using the development research method using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Data collection techniques are validation sheets and response questionnaires. Based on the results of validation I 83.2%, validator II 92.8% and validator III 89.6%, the average score of expert validators from the expert validation sheet is 88.53% with very good criteria of virtual book. Based on the data from the implementetion results involving 16 students as respondents, an average percentage of 92.18% was obtained, so it can be concluded that the students responses to the virtual book media were very interesting.

Conceptual understanding of chemistry requires the ability to represent and interpret the problems of chemicals in a form that is easy to understand. One way that allows students to learn chemistry is to implement effective learning activities. This research was conducted in SMA Negeri 11 Banda Aceh. One of the schools with a homogeneous class management systems based on the same gender. The purpose of this study was to determine the learning process for the chemical held in a homogeneous class. Definition of homogeneous classes of this research is the class that is populated by students collectively have the same gender. Observations obtained is the percentage of teachers' activities with a percentage of 71.42% of activities, which means that activities of teachers in the classroom in both categories (51% - 80%). Results of student feedback through a questionnaire, obtained only 32% of students from a total of 88 students who find it easy to understand the chemistry lesson taught over the years, while the remaining amount to 68% of students still find it difficult to understand the chemistry lesson. Chemistry learning in homogeneous classes requires readiness of teachers, both in the preparation of learning tools and also the ability of teachers to manage the classroom, so that learning can be effective.

Based on observations at SMAN 1 Baitussalam, information was obtained that learning outcomes of students on acid-base material were still low, this was caused by the process of learning chemistry that was still teacher-centered and didn’t use specific learning models. The STEM learning model is a One learning model that can be used as solution to this problem is the learning model of Science, Technology, Engineering, and Mathematics (STEM). The purpose of this study was to obtain information about the effect of the STEM learning model on learning outcomes and student responses, especially on the concept of acid-base in SMAN 1 Baitussalam. This study uses Quasi Experimental design, with data collected through test and questionnaires. Student test results were analyzed using SPSS Version 23.0, where the significance value obtained from the t-test analysis was 0,000<0.05 so it can be seen that Ho was rejected and Ha was accepted. Student responses obtained through questionnaires analyzed based on the percentage answers provided by students, the results showed that 93% responses of students were very interested in the STEM learning model. These results indicate that STEM learning model is effective in improving student learning outcomes in SMAN 1 Baitussalam, especially in acid-base concept.
