The use of the right tools greatly determines the success of achieving the competence of students in learning. Learning tools that tend to be monotonous make students less actively involved in learning and less improve scientific attitudes and learning outcomes. The development of Chemistry learning tools based on a scientific approach in NHT model is expected to be effective in the classroom and help students in learning Chemistry. This development research aims to: 1) describe the development process of producing cooperative learning tools of NHT type based on a scientific approach; and 2) produce cooperative learning tools of NHT type based on scientific approaches that are valid, practical, and effective to improve scientific attitudes and learning outcomes on Acid-Base learning material. This research consists of the stages of defining (define), design, development, and dissemination (disseminate). The product developed was tested on students of class XI MIPA.3 at SMAN 8 Gowa of academic year 2019/2020. The product validity was tested by two expert assessors. This research includes the steps of the NHT model, namely preparation, group formation, problem discussion, calling the Member Number or Giving Answers, giving conclusions, and giving awards. The stages of this chemistry learning tool also refer to the scientific attitude approach that applies 5M, namely observing, asking, trying, associating/processing information/logic,and communicating to improve scientific attitudes and learning outcomes of students. The results of the study obtained: 1) the average value of product validity 3.76 (very valid); 2) scientific attitude questionnaire data = 3.07 (high); 3) THB's average N-Gain result is 0.83 (high); 4) teachers and students showed a very positive response with a percentage of 95.84% and 82.81%. Therefore, the conclusion of the study is the Chemistry learning tools based on the scientific approach in NHT model that had been developed in Chemistry learning on Acid-Base learning materials are valid, practical, and effective to improve the scientific attitude and learning outcomes of students.

The problems encountered in learning biology in SMAN 13 Tebo is the low result in learning biology, and the class average (57 and 58) of minimal completeness (KKM). The causes include the lesson still done traditionally, the class still focus on the teacher as main source of knowledge. Objective of this study to determine the influence of the biology of learning outcomes: the student taught by using media (powerpoint) contextual and those taught by using traditional approach, student of high scientific attitude and low scientific attitude, and presence or absence of interactions between media (powerpoint) contextual approach and scientific attitude toward the biology learning result. This research is an experiment research with factorial design 2x2. Methods research design used in this study is a quasi experimental pratest and postest. The data are analyzed using two way ANOVA. Results of this research indicate that there is a influence in learning result between student taught by using media (powerpoint) contextual and those taught by using traditional approach, there is no influence in learning result between student of high scientific attitude and low scientific attitude, and there is no interaction between media (powerpoint) contextual approach and scientific attitude toward the biology learning result.

 AbstractThis research aimed at knowing the effect of using TPS learning model with ICM media toward student chemistry learning achievement on Hydrocarbon lesson at the tenth grade of State Senior High School 2 Rumbiojaya. It was instigated by the low of student chemistry learning achievement on Hydrocarbon lesson at the tenth grade of State Senior High School 2 Rumbiojaya. It was a Quasi-experiment with pretest and posttest design. Two classes of the tenth-grade students owning the same homogeneity level were the samples, the tenth grade of classes 2 was as the experimental group and class 3 was as the control group, and Purposive sampling technique was used. Observation, homogeneity test as the preliminary data test, pretest and posttest as the final data test, and documentation were the techniques of collecting the data.  t test used to analyze the final data showed that tobserved was 2.038 and ttable was 2.00 at 5% significant level.  It meant that tobserved was higher than ttable, H0 was rejected, and Ha was accepted.  It revealed that there was an effect of using TPS learning model with ICM media toward student learning achievement on Hydrocarbon lesson and the coefficient of effect was 8.6%.Keywords : Think Pair Share, Index Card Match, Learning Achievement, Hydrocarbon.
