Mathematical Literacy is one of the abilities that must be possessed by students in learning mathematics. Learning that improves mathematical literacy can build students' knowledge and understanding of a mathematical concept. Having mathematical literacy can involve individuals in using existing procedures and using knowledge of competence and self-confidence to apply their knowledge in everyda…
In the 21st century in the world of education, one of the skills needed is mathematical communication skills. The results of PISA 2018 showed that Indonesia's mathematical ability out of 73 countries was in 7th position from the bottom. The skills tested by PISA include communication and using mathematical symbols. Communication skills can be optimized if teachers know the extent of students' m…
Problem solving is the core of mathematics learning, but many students experience difficulties due to the lack of effective strategies in understanding and solving problems. The mathematical problem-solving ability of junior high school students is still relatively low, this is caused by the lack of conceptual understanding that students have, so they tend to only memorize formulas without unde…
Mathematical representation ability is the ability to present notation, symbols, tables, images, graphs, diagrams, equations or other mathematical expressions in another form. Mathematical representation consists of visual representations, images, written text, equations or mathematical expressions. Mathematical representation ability is one of the most important skills for children to have and…

Abstract: This study aims to examine the effectiveness of implementing the team assisted individualization (TAI) cooperative learning model in improving student learning outcomes on hydrocarbon material in Grade XI at SMA Negeri 2 Dumai. The research employed an experimental method using a pretest-posttest control group design. The study sample comprised two classes: the experimental class, whi…
Abstrak : The problem in this study is the low chemistry learning outcomes of class XI students of SMA Negeri 6 Pekanbaru. Another problem that emerged based on initial observations made by the researcher was the lack of student motivation in chemistry learning. One of the causes of low student motivation is the limited use of media in the learning process. The objectives of this study are: 1) …
The Independent Curriculum encourages flexible and student-centered learning that emphasizes in-depth understanding with the UbD approach. However, the chemistry assessment, especially on the salt hydrolysis material in SMA Negeri 4 Pekanbaru and SMA Negeri 6 Pekanbaru, has not been fully oriented towards student understanding and tends to only measure low-level cognitive aspects, so that this …
This study aims to develop E-LKPD based on the CORE (Connecting, Organizing, Reflecting, Extending) learning model by utilizing the Liveworksheets web application on the reaction rate material for grade XI of high school. The development was carried out using a 4-D model that includes the stages of defining, designing, and developing. The results of validation by material and media experts show…
Students and educators must also be able to use technology such as gadgets because learning media will also be more focused on technology such as platforms on gadgets so that learning has variations that can build students' enthusiasm for learning in the learning process. This development research aims to produce E-LKPD based on experiential learning using liveworksheets on acid-base material f…
Pemahaman konsep dalam pembelajaran kimia memiliki peran penting dalam membentuk pengetahuan ilmiah yang utuh pada peserta didik. Namun, kenyataannya masih banyak peserta didik yang mengalami miskonsepsi yaitu pemahaman keliru yang bertentangan dengan konsep ilmiah yang sebenarnya. Miskonsepsi ini seringkali terjadi pada materi yang bersifat abstrak seperti struktur atom, di mana peserta didik …

Salah satu inovasi yang dapat dilakukan oleh guru dalam mewujudkan pembelajaran efektif, efisien, dan interaktif melalui pengembangan perangkat pembelajaran berupa bahan ajar berbasis elektronik s…
Proses pembelajaran berperan penting dalam mencapai tujuan pendidikan, khususnya dalam membangun kemampuan berpikir kritis, kreatif, dan pemecahan masalah seperti yang ditekankan dalam Kurikulum Merdeka. Proses pembelajaran kimia, terutama pada materi kesetimbangan kimia yang bersifat abstrak, peserta didik sering menghadapi kesulitan memahami konsep dan menyelesaikan masalah. Data di SMA Neger…
Learning plays an important role in shaping students' understanding, but many teachers still use conventional methods that are less varied, leading to less interesting and unmotivating learning, especially in chemistry subjects. The results of observations show a lack of teaching materials and chemical experiments that can improve students' understanding and motivation. This study aims to devel…
Permasalahan ditelusuri melalui observasi dan bersama guru kimia di SMA Negeri 8 Pekanbaru dan SMA Negeri 5 Pekanbaru. Pra-penelitian menunjukkan bahwa sebagian peserta didik masih kesulitan dalam memahami materi reaksi redoks yang ditunjukkan dari hasil belajar yang masih berada di bawah KKTP. Kondisi ini dapat ditinjau dari proses pembelajaran di kelas, salah satunya melalui penggunaan bahan …
The development of science and technology has a major impact on the world of education, including in the development of teaching materials. One innovation that can be utilized is an electronic module (E-Module) which is more practical and interactive than conventional open materials. This study aims to determine the validity of the discovery learning-based e-module on hydrocarbon material for g…
The development of science and technology (IPTEK), has a major impact in the field of education. Along with the development of science and technology, the education system must adjust these developments to improve the quality of education. Currently we are faced with the era of Society 5.0 which emphasizes integrated, easy, and fast life so that human life is more practical. Indonesia's effort …
