Students' conceptual understanding of chemistry material is very important because good conceptual understanding can help to solve a problem, connect it with other relevant knowledge, and make it easier to study related material. This research aims to describe students' conceptual understanding of atomic structure and SPU material. This study employs a qualitative descriptive research method and approach. The research instrument is a multiple-choice test, with 25 questions divided into six indicators. We collected data through written tests. The data analysis process employs descriptive statistics, specifically using percentages. The research shows that students have a good understanding of all of the indicators. They understand that 42.59% of students in the sufficient category understand how electrons, protons, and neutrons relate to isotopes, isotones, and isobars. However, 33.70% of students in the poor category understand and can figure out the electron configuration. 19.16% of students in the very poor category can figure out the quantum number. 32.10% of students in the poor category can figure out periods and groups in SPU. And 32.10% of students in the less category have a good understanding of the periodicity of elements. The research results show that there is a need to improve the learning process, either through the application of learning models or the use of appropriate learning media, so that students' conceptual understanding can increase.

This study aims to determine the effect of the TGT-type cooperative learning model assisted by PowerPoint-based cards on chemical bonding material on student learning outcomes. This type of research is a type of experimental research with a quantitative approach. The population in this study were all students of class X MIPA at SMA Negeri 15 Medan. Samples were taken by purposive sampling of 2 classes. The treatment of the two sample classes was distinguished by the use of the TGT learning model in the experimental class while the control class used the conventional learning model with the same media. The instrument used was a multiple choice test instrument with 20 questions. Data were analyzed by normality, homogeneity, and twoparty hypothesis testing with a significance level of 0.05. the results of the data analysis show that: There is an influence of the PowerPoint-based card-assisted TGT type cooperative learning model on student learning outcomes in chemical bonding material where the average value of students taught with PowerPointbased card-assisted TGT type cooperative learning model on student learning outcomes in bonding material chemistry was significantly higher at 81.11 in the experimental class than the average value of students who were taught with conventional PowerPoint-based card-assisted learning models on student learning outcomes in chemical bonding material of 73.75 in the control class.
