This is a development research that aims to evolve a learning instruments discovery learning model based on the SKKNI on volumetric analysis subject that are valid, practical, and effective. The development model used in this study refers to the 4D, which consists of the defining, design, development, and dissemination. The learning instruments developed are RPP, LKPD, Student Learning Materials, and THB. The SKKNI-based discovery learning model volumetric learning device that was developed was then validated by two experts. After validation, a learning device trial is then conducted at the SMK-SMAK Makassar in class XI E with a total of 35 students. The results of the study indicate that the SKKNI-based discovery learning model developed after being validated was very accurate (V = 3.75). The learning device is stated to be practical because the practicality test related to: (1) the implementation of the learning device is in the fully implemented category (M = 1.86) included in the category (1.5 ≤ M ≤ 2.0), (2) the teacher gave a very positive response with a percentage of 93.49%, and (3) the students gave a very positive response with a percentage of 91.93%. This learning device also meets the effectiveness criteria, which are reviewed through learning outcomes with a classical percentage of completeness 94.00%. Therefore, the results of the study indicate that the developed learning device products meet valid, practical, and effective criteria.

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 aim of this article is to examine the effects of influences during a pandemic period to improve learning outcomes in chemical materials. The method used is meta-analysis by summarizing, analyzing, and analyzing data from the literature and processed statistically. During the pandemic, teachers must be creative in learning because the learning process is carried out in a bold manner. As facilitators, teachers can facilitate students by providing digital handouts that can be accessed more easily without the internet. In addition, the use of handouts has a strong influence on improving student learning outcomes. The increase in student learning outcomes can be observed through paired sample statistical tests and the effect size of learning outcomes between before use and use of handouts. The use of handouts as an alternative to teaching materials can improve learning outcomes by 38.6%. This shows that digital material can be used as an alternative to chemical teaching materials during the pandemic.

This study aims to analyze the effectiveness of handouts as an alternative to learning chemistry in improving student achievement. The method used in this article is a meta-analysis of several pieces of literature relevant to the topic and research objectives. The handout was identified as having an optimal level of practicality, and was considered adequate for students because it made it easier for students in the learning process. The teacher's role in this method is more to strengthen the material by providing an understanding of the inappropriate material delivered by the group. The teacher and the students concluded the results obtained, and an assessment was carried out to determine the level of achievement of the cycle I. In the next stage in cycle II, the group assistants were expected to understand other students so that interactions between students were identified as contributing to the second cycle assessment results. The result is an increase in student achievement in both cognitive and affective aspects. The cognitive aspects previously at the level of achievement of 42.11% increased to 63.16% exceeding 60%. Meanwhile, the affective aspect increased from 70.24% to 74.47%. The combination of discussion methods and handouts, and also videos as learning media can improve student learning outcomes or student achievement more effectively.

This study aims to increase the learning motivation of students in studying the subject matter of chemical equilibrium. Therefore, we developed learning application based smartphone in a problem-based learning model that called ChemOnPhone which is valid, practical and effective to use. To achieve this aim, we followed the Hannafin and Peck's model development phases: analysis, design, development and implementation. The ChemOnPhone we built had been through validation processes by an educational media and a subject content experts. We then revised the app accordingly by considering these expert reviews until the app considered as valid. To evaluate the practicality and the effectiveness of the app, we then tried it out to Year XI Science students of SMAN 2 Sidrap. The results of media validation and trial showed that: (1) the media was very valid (marked 3.93 out of 4), (2) the content was valid (marked 3.01 out of 4). ChemOnPhone was also considered practical and effective based on (1) The implementation was graded as effective (M = 1.85, 1.5 ≤ M ≤ 2.0), (2) The approval rate was 97.2% and 86.4% by teachers and students, accordingly. ChemOnPhone has met the effective criteria as (1) students learning motivation improved from 60.9% out of 84.4%, (2) students learning activity was averagely 87.5%, which met the active criterion, and (3) the average learning results achieved was 88.4% out of 100%, which pass the effective criteria of ≥ 80%. Overall, ChemOnPhone was valid, practical and effective to use in learning the chemical equilibrium subject.
