The aims of this study were: (1) to recognize the implementation of chemistry learning. (2) to identify the assessment conducted by the teacher in chemistry learning process. This study was an evaluation study with formative approach from Scriven. Evaluation was performed in chemistry learning process. The study was conducted at SMA N 1 Banguntapan (Senior High School). The respondents were 58 students. The instruments of the study was questionnaires with sumative rating scale models that modify the Likert scale. Data analysis techniques was quantitative descriptive, analyzed by using excel program thus was presented in the histogram to illustrate the achievement of the learning process and assessment conducted by the teacher. The results of this study were: (1) the achievement of the chemistry learning process was divided into 3 stages: the preliminary sections indicated a good category (pronounced by 55.17% respondents), the learning model revealed a good category as well (pronounced by 51.73% respondents) and the practicum indicated the very good category (pronounced by 55.17% respondents); (2) the learning assessment conducted by the teacher was in the good category, (pronounced by 65.52% respondents). Overall evaluation results show that the chemistry learning done by the teacher was good.

The purpose of this study (1) to find out how the application of the Student Teams Achivement Division (STAD) learning model can increase students’ learning activities/activeness; (2) to determine the improvement of students’ learning activities/activeness using the STAD type cooperative learning model; (3) to know the learning outcomes of oxidation reduction concept by using the STAD type cooperative learning model. The research was conducted in class X MIPA 2 at SMA N 1 Banguntapan even semester of 2019/2020 academic year. This study is a classroom action research. The cycles consist of cycle I and cycle II. Each cycle went through the stages of planning, implementing, observing, and reflecting. At the end of the cycle a non-test was conducted in the form of a questionnaire to measure the students’ activities/activeness and a test to measure the students learning outcomes. The result showed (1) the application of the STAD learning model, namely the phase 1 to phase 6 of the concept of redox definition, the determination of good category oxidations stated (77.5%) in cycle I and the concept of oxidizing reducing agents, disproportionation and conception reactions were very good (87.5%) in cycle II. (2) The application of the STAD learning model of oxidation reduction could increase the students’ activities/activeness by 60.51%, the category was quite active in the first cycle to 75.31% the active category in the second cycle. (3) The application of the STAD learning model for oxidation reduction concept could improve the learning outcomes of Chemistry of grade X MIPA students at SMA N 1 Banguntapan by 64% in cycle I, increasing to 78% in cycle II.
