<![CDATA[The purpose of this research was to know the effectiveness of student centre learning (SCL) based experiment method to increase student achievement on topic acid-based solution, type of this research descriptive qualitative, this research was conducted in SMAN 16 Medan the sample that used in this experiment consist of two class which is grade XI IPA1 as experiment class that treated by using student centre learning and Grade of XI IPA 2 as a control class with about student centre learning-based experiment method. Data in this research got from pretest which is given before treated the method and posttest after treated the method. In experimental class, the mean before teaching treatment is = 34, while after giving treatment the mean is increase become 70. In controlled class, the mean before teaching treatment is = 29, while after teaching treatment it changes become 42. The study concludes that the SCL based experiment method is an effective method in the teaching of the acid-based solution to increase student achievement.]]>

<![CDATA[This study aimed to determine the representation ability of students in learning chemistry. The ability of representation consists of three levels, namely macroscopic level, submicroscopic level, and symbolic level. This study was a descriptive study. The subjects in this study were 53 XI grade students. The study instrument was in the form of a description test compiled based on indicators of representation ability. The results showed that the average score of students’ representation ability at the macroscopic level is 66.94, and is in the good category. The average score of students’ representation ability at the submicroscopic level is 47.17, and is in the medium category. The average score of students’ representation ability at the symbolic level is 64.30, and is in the good category.]]>

<![CDATA[This study aimed to determine the effect of animation media in discovery learning model on the students’ representation ability on chemical equilibrium materials. This study was an experimental study using post-test only group design. The study population consisted of 6 classes or 127 students. The sampling technique was done by using purposive random sampling, and 2 classes were chosen consisting of 53 students. Data were collected using a representation ability test which included macroscopic ability, submicroscopic ability, and symbolic ability. By using the inferential analysis of the Mann Whitney test, it was obtained that the significance value for the macroscopic ability was 0.003, the submicroscopic ability was 0,000 and the symbolic ability was 0.041. The significance value is smaller than α = 0.05. Referring to that, it can be seen that there is an influence of animation media in discovery learning model on the students’ representation ability on chemical equilibrium material.]]>

<![CDATA[Kemampuan simbolik adalah kemampuan representasi yang berkaitan dengan penggunaan simbol, rumus, dan persamaan kimia. Kesulitan siswa dalam mempelajari materi kimia yang abstrak salah satunya terjadi karena tingkat representasi simbolik yang rendah. Penelitian ini merupakan penelitian tindakan kelas (PTK) yang menggunakan model pembelajaran discovery. Model pembelajaran ini merupakan salah satu model pembelajaran yang disarankan pada pembelajaran berbasis kurikulum 2013. Penelitian ini dilaksanakan dalam 2 siklus dan setiap siklus terdiri dari 2 pertemuan. Subjek penelitian terdiri dari 24 orang. Hasil penelitian menunjukkan bahwa terjadi peningkatan kemampuan simbolik siswa dari siklus 1 dengan nilai rata-rata 53,08 (indikator keberhasilan cukup) menjadi 72,58 (indikator keberhasilan tinggi) pada siklus 2.]]>

<![CDATA[The research is Classroom Action Research, which aims to improve basic chemistry student learning outcomes with the application of Treffinger's learning model with the help of audio visual media on colloidal system materials. Data collection techniques can be done with an observation sheet of student learning activities and evaluation at the end of each cycle. The collected data is analyzed using descriptive statistical analysis. The results showed that the application of Active Knowledge Sharing strategy with Buzz Group method can improve basic chemistry learning outcomes in STKIP PI Makassar students which is characterized by an increase in the average learning outcome of cycle I students by 63.33 and cycle II by 72.67 and an increase in the completion of learning outcomes in cycle I which is 9 people or 22.5% and cycle II 35 people or 87.5%.]]>

<![CDATA[Due to the COVID-19 pandemic, lectures must be conducted online. This research is a survey research to find out the perception of students in participating in online learning. Survey of Musamus University students in 6 faculties with a total of 262 respondents. Respondents were selected by proportionate stratified random sampling. The instrument used is a questionnaire made in google form with a total of 21 questions. Data analysis was carried out by calculating the percentage of each answer for each question item. Through this research, the results obtained are (1) Students realize online learning is a learning solution during the Covid-19 pandemic; (2) Students are happy with participating in online learning; (3) Students are enthusiastic to complete assignments; (4) Students realize that through the assignment of lecturers their knowledge is increasing; (5) Students find online learning beneficial for them; (6) Students have mastered the use of online learning platforms; (7) Students hope that online learning will no longer be carried out in the future. Students also prefer face-to-face learning compared to blended learning and online learning, but some students have realized that the blended learning model is an alternative in learning that can be applied in the future]]>
