<![CDATA[Misconceptions can be in the form of initial concepts, mistakes, incorrect relationships between concepts, intuitive ideas or naive views. From the explanation that has been described misconception is interpreted as an initial concept owned by students that is not in accordance with the generally accepted explanation as a result of the experience constructed by students. Misconception can also be called an alternative concept. This study aims to determine the misconceptions of Class X students of Natural Sciences 2 of SMA Negeri 1 Remboken on atomic structure material. Data collection uses questions in the form of a two-tier diagnostic test, which was tested on 20 students. From the results of the study concluded that students who understood the concept of 82.75%, and students who experienced misconceptions as much as 11.25% while students who did not understand the concept of 6% in the Atomic Structure material.]]>

<![CDATA[This research is an experimental study using the Anchored Instruction learning model. This study aims to determine the effect of the Anchored Instruction learning model on student learning outcomes on the mole concept subject. This research was conducted in class X SMA Negeri 2 Siau Timur with a sample of 40 people. The research design used was a pre-test and randomized two group design. The experimental class uses the Anchored Instruction learning model and the control class uses the conventional learning model. Analysis of the hypothesis test using t-test with a significant level α = 0.05. The test results obtained indicate that the results of tcount> ttable or 2.112> 2.024, thus H0 is rejected and H1 is accepted, this shows that there is a significant difference between the average value of the initial test (posttest) of the experimental group and the control group. So it can be concluded that there is a difference between student learning outcomes using the Anchored Instruction learning model and student learning outcomes using conventional learning models on mole concept subject.]]>

<![CDATA[The impact of the use of refined petroleum on potential pollution in mangrove allows the presence of lead metal (Pb) in the Sangihe Islands Restoration and Learning Center and the use of mangroves in the Sangihe Islands Restoration and Mangrove Learning Center as a place of learning has not been carried out to the full. Therefore, in this regard, a study was carried out by analyzing Pb metals in sediments, Gastropod shells and Bivalvia shells in the research subsystem zone of the Sangihe Islands Restoration and Mangrove Learning Center which were then designed into learning designs using a model of problem based learning. The research method used is an exploratory method. Pb metal analysis was performed using an Atomic Absorption Spectrophotometer instrument resulting in an average Pb metal in sediments was 0.402 ppm, in Bivalvia shells was 0.04283 ppm and Gastropods shells was 0.0654 ppm. Based on the results of the analysis, it can be concluded that the presence of Pb metal in sediments, Bivalvia shells and Gastropod shells then yields four main questions in the learning design with Sub-Impacts of the Use of Petroleum using the problem based learning model.]]>

<![CDATA[The purpose of this study was to determine the level of understanding of concept maps of semester II chemistry students using a three-tier diagnostic test on electrochemical subjects with multimedia-based learning. The research was carried out in the Department of Chemistry, FMIPA, UNIMA in the even semester of the 2018/2019 school year. The research method used is One-shot Case, with a sample of the research that is a class of chemistry classes for a certain year as many as 12 people. Multimedia instruments are made by utilizing animation and video from the internet which is packaged in Ms. Power point, and the electrochemical three-tier diagnostic test instrument is made according to the subject being taught. Then the test instrument was validated and 15 questions were produced. It was found the map data on the level of understanding of electrochemical concepts namely the average number of students who understood the concept by 41.6%, the average number of students experiencing misconceptions both misconceptions (+), misconceptions (-) and misconceptions by 30.033%, average number students do not understand the concept as much as 11.1%, there are 8.3% students who are not sure of the concept they have, and 8.3% there are students who do not understand the concept of electrochemistry. Thus, it was concluded that a three-tier electrochemical diagnostic test was able to reveal a map of students' level of understanding of the chosen topic]]>

<![CDATA[This study aims to determine the effect of POGIL learning models on student learning outcomes on acid-base titration subject. This research was conducted in class XI MIPA 2 and XI MIPA 3 in SMA Negeri 1 Kakas. The method used is an experimental method with a post-test only control design research design. The research sample consisted of 30 students, who were randomly drawn. The experimental class uses the POGIL method, the control class uses conventional learning. Student learning outcomes data obtained from post-test scores. Analysis of research data shows that there are differences in the average value of student learning outcomes of the experimental class taught by using the POGIL method and the average value of the learning outcomes of control class students who are taught by using conventional learning on mole concept material. Data analysis using t-test at a significant level α = 0.05. Statistical analysis of student learning outcomes obtained tcount > ttable or 3,078 > 2,048. So it can be concluded that there is a positive influence between student learning outcomes using the POGIL method and student learning outcomes using conventional learning on acid-base titration subject.]]>

<![CDATA[Penelitian ini bertujuan untuk mengetahui besarnya pengaruh penerapan strategi pembelajaran REACT terhadap hasil belajar siswa pada materi konsep asam basa menggunakan konteks kimia. Penelitian ini dilaksanakan di SMA Negeri 1 Tondano pada tahun ajaran 2019/2020 di kelas XI IPA 1 dengan jumlah siswa sebanyak 23 orang. Materi konsep asam basa yang diajarkan di kelas XI IPA 1 dikaitkan dengan kehidupan sehari-hari. Hasil pengolahan data hubungan antara nilai angket dan posttest menunjukan respon positif dalam pembelajaran menggunakan strategi pembelajaran REACT. Data hasil penelitian berupa angket dan posttest dianalisis melalui uji hipotesis yaitu uji regresi sederhana dan uji korelasi product moment. Uji regresi sederhana menunjukan bahwa semakin tinggi sikap siswa terhadap strategi pembelajaran REACT (X) maka semakin tinggi hasil belajar siswa (Y), hal ini menunjukan adanya pengaruh variabel X (sikap) dan variabel Y (hasil belajar). Hasil uji korelasi product moment diperoleh nilai rxy yaitu 0,6466 yang menunjukan tingkat hubungan yang kuat. Hasil koefisien penentu untuk mengetahui pengaruh pembelajaran REACT terhadap hasil belajar diperoleh sebesar 41,82%. Dari hasil yang diperoleh dapat dilihat bahwa terdapat pengaruh penerapan strategi pembelajaran REACT terhadap hasil belajar siswa pada materi konsep asam basa menggunakan konteks kimia.]]>
