This study aims to determine the effect of flipped-classroom based on guided inquiry learning system on students' learning outcomes of class XI students in SMA Negeri 8 Padang. The subject in this study were students of class XI MIPA 2 as the experiment class and students of class XI MIPA 1 as the control class using purposive technique sampling. The type of research is experimental quasi-equivalent control study design groups. The technique of data analysis used is two means similarity test (t-test). The object of this study is students’ learning outcomes on reaction rate material. The instruments of this study is used in the formative test consists of the initial test (pretest) and the final test (posttest) with 17 numbers of multiple choice questions based on the learning objectives. The difference between the pretest and posttest scores for experiment class is 48,77 while for the control class is 41,18. Data analysis shows that the subject are normally distributed and homogeneous so the t-test can be done, and the value of thitung obtained is 1,71. This proves that the learning outcomes between experiment class and control classes have significant differences. Based on data analysis, it shows that flipped-classroom based on guided inquiry learning system has proven the improve students' learning outcomes significantly.

During learning process students tend to be passive and memorize with teacher’s explanations. This causes students’ critical thinking skills in finding solutions problems that do not develop optimally. Qualitative descriptive research aims to describe students’ critical thinking at XI IPA 1 grade of SMAN 7 Padang skills in solving chemistry problems on reaction rate material. The research sampling technique used purposive sampling in the XI IPA 1 grade with 38 students. The research data will be analyzed using the qualitative analysis technique of the Miles and Huberman (1984) model consists of data reduction, data display and verification. The research instruments are problem test with 5 questions referring to critical thinking indicators by Ennis (1985) including elementary clarification, basic support, inference, advanced clarification, strategies tactics and interviewing selected students. The results showed that RF subjects of students with high critical thinking skills 4 critical thinking indicators, such as elementary clarification, inference, advanced clarification, strategy and tactics. AM subjects with medium critical thinking skills fulfill 3 critical thinking indicators, elementary clarification, basic support, and inference. While the subject of AZ students with low critical thinking skills only fulfills 2 critical thinking indicators, constist of advanced clarification ,strategy and tactics.

Literature Review: The Use of Tetrahedral Chemistry Representation in Chemistry Learning Rosy Novita; Faizah Qurrata Aini
Entalpi Pendidikan Kimia Vol 3 No 2 (2022)
Publisher : Universitas Negeri Padang

Chemistry is a science that studies phenomenology and abstraction. Then chemistry is related to all things that exist in nature. Therefore, this study aims to discuss the use of tetrahedral chemistry representation in chemistry learning. The research method used is literature study or library research. Meanwhile, the data sources used are secondary data obtained from various sources such as journals, books, and other sources relevant to the research. The results showed that learning with tetrahedral chemistry representation is very suitable for 21st century learning and the 2013 curriculum. The use of tetrahedral chemistry representation can help in understanding abstract concepts. Then students can use chemistry appropriately to solve complex problems in real life. The tetrahedral chemistry representation can also define and design the future of chemistry and chemistry education

Studi Literatur: Pendekatan Human Element pada Buku Teks Chemistry Human Activity, Chemical Reactivity Karya Mahaffy dkk Materi Kesetimbangan Asam Basa dalam Larutan Widia Hizriati; Faizah Qurrata Aini

Publisher : Universitas Negeri Padang

A variety of skills have shaped the teaching and learning of chemistry in the early 21st century. This includes fundamental changes in chemistry such as changes in understanding of how students learn, the application of computer and information technology in studying complex scientific phenomena, and others. Responding to this problem, chemistry education which originally used a "triangle shape" must be emphasized into a "tetrahedral" form, where the fourth peak represents the human context in studying chemistry or is called the human element. Highlighting the human element provides compelling reasons to emphasize case studies, active learning, and investigative projects to link school chemistry to everyday life. This study aims to describe the phenomena that exist regarding the human element in chemistry learning, especially in textbooks. This research is a qualitative research with descriptive analysis technique with library research. The data used are secondary data derived from textbooks and scientific articles. The existence of human activities involved in learning chemistry provided in textbooks, helps students learn from rich contexts. Learning from a rich context makes learning chemistry more motivating, interesting and relevant to their lives, thus helping students understand chemical concepts well. Therefore, the importance of the human element involved in learning chemistry, especially in textbooks.

Publisher : Universitas Negeri Padang

This study aims to determine the categories of validity and practicality of the e-modules that have been produced. The type of research is classified as a 4-D model, which has four stages, namely the define, design, develop, and disseminate stages. The instruments used are a validation sheet and a practical sheet in the form of a questionnaire sheet. The resulting product was tested for validity by 5 validators, consisting of 3 lecturers majoring in chemistry at FMIPA UNP and 2 teachers from SMAN 1 Rao, Pasaman Regency. Practicality tests were carried out by 2 chemistry teachers along with 15 students in class XI MIPA SMAN 1 Rao, Pasaman District. Based on the validation results, the value of kappa moment (k) is 0.86. The practicality of teachers and students is then obtained by the average value of kappa moment (k) of 0.90 and 0.88. The value obtained indicates that the resulting e-module is categorized as very valid and practical.

Publisher : Universitas Negeri Padang

This study aims to describe the effect of using scientific approach based learning model on students’ learning outcomes. The method is literature review. The data used in this study is secondary data. This secondary data was obtained from books and scientific articles. The research procedure was carried out through several stages, namely designing the topic and research objective, conducting review, analyzing data, and writing review. The result of this literature study show that the use of Problem Solving and Problem Posing learning models using tetrahedral chemistry representation has an effect on student learning outcome. Other learning models such as Problem Based Learning, Project Based Learning, Constructive controversy, and Guided Inquiry that use tetrahedral chemistry representation do not have a significant effect on student learning outcome. In other words, these four models give the same good result to student learning outcome.

The use of teaching materials that have been developed must have a practical category so that teaching materials can be used in the field. This study aims to determine the practicality of the Discovery Learning-Based Chemical Equilibrium E-Module equipped with a Virtual Laboratory. This research is a continuation of previous research, namely research and development research using the plomp development model. This research stage is in the prototyping stage, precisely in prototype III to the assessment stage. The place of this research is located at SMAN 14 Padang. Analysis of the data obtained using the Aiken'V formula. The one to one evaluation test showed that the e-module was interesting both in terms of cover and content, it was clear in the presentation of the material, the language used was easy to understand, the video display made the material easier to understand. Based on the data analyzed by the aiken V formula, in the small group stage a V value of 87,6% was obtained with high practicality, and in the field test stage a V value of 85,1% was obtained in the high category. This data can be proven by the ability of students to solve problems in module E of 78.86% with a very high category.
