Problem Based Learning model is a problem-based learning model that exposes students to practical problems to be solved that focus on the final results. The purpose of this study is to find out whether the Problem Based Learning learning model on atomic structure material is better than conventional learning models. The population in this study were all class X students of Santa Rosa de Lima Tondano Catholic High School. The sample of this study was class XA and class XB Catholic School Santa Rosa de Lima Tondano with the number of students 30 people, for the experimental class 15 people and the control class 15 people, in the even semester the academic year 2018/2019.Hypothesis testing uses the t-test to see differences in student learning outcomes between the experimental class and the control class. Based on the results of the study obtained the value of t_count (4.21)> t_table (1.701) at the real level α = 0.05. So that H_0 is rejected and H_1 is accepted. where the average value obtained in the experimental class 82.66 and the average value for the control class 71.33. So the conclusion is that there is a positive effect of the implementation of the Problem Based Learning learning model on atomic structure material on student learning outcomes at Santa Rosa de Lima Tondano Catholic High School.

Every student has different cognitive structures, but few teachers realize these differences. The purpose of this research is to identify students’ cognitive structures, which comprise of several aspects such as content, students’ prior knowledge, new knowledge and misconception when they learn from a concept map. The method used is descriptive research, conducted on 18 students at a senior high school in Manado City. The students’ cognitive structures are revealed using questions from concept map about acid-base solution. The cognitive structures are identified based on the scores obtained by each students from the concept map questions. The result shows three cognitive categories of students on the content aspect, namely poor, good, and excellent, and three categories of students’ cognitive structures, which are students’ prior knowledge, new knowledge and misconception. In general, the students’cognitives structure are categorized as good.

This study aims to determine whether there are differences in the average student learning outcomes taught with the Inquiry Training learning model and the Group Investigation learning model on electrolyte and non-electrolyte solution material. This research was conducted at SWADHARMA WERDHI AGUNG High School in second semester of 2017/2018. The research method used is the experimental method. Sampling is done by random sampling technique. The sample in this study was class XA students as experimental class I and class XB as experimental class II. Each sample amounted to 20 respondents, and the total number of respondents was 40. Data collection techniques were pretest and posstest and the instruments used to measure learning outcomes were multiple choice tests. Analysis of the posttest data of the two groups used the t test. The results of the research obtained were tcount of 2,233 and t table at a significant level of 0,05 of 2,024, then tcount> ttable. Then H0is rejected and H1is accepted. Thus it was concluded that there were differences in the average learning outcomes of students taught using the Inquiry Training learning model and the Group Investigation learning model.

Kajian penerapan metode praktikum secara efesien pada materi korosi di SMA YPPK st. Thomas aquino Kaimana Theresia N. R. Boce; Emma Juline Pongoh; Rymond Jusuf Rumampuk

The application of practicum methods efficiently is able to help educators to achieve success in the chemistry learning process. This study aims to determine student learning outcomes in corrosion material through the learning process by applying the practicum method. This research was conducted in the odd semester of the 2018/2019 academic year for students of class XII Science in YPPK High School St. Thomas Aquino Kaimana. The sample used in this study is all students of class XII IPA St. Thomas Aquino Kaimana. The indicator used in this study is individual success, that is, if the student has reached the value of 75. Analysis of the data in this study used the percentage completeness learning technique based on the results of the indicators obtained. The results showed that from the initial test of student learning outcomes had not reached completeness (value 75) with the percentage of completeness of learning outcomes of 0% and from the final test the results of student learning had reached a grade (value> 75) with a percentage of completeness of learning outcomes of 100%. Based on the results of this study it can be concluded that the learning outcomes of students in the subject matter of corrosion with the practicum method were increased.

The purpose of this study was to determine the improvement in learning outcomes of class X students in East Halmahera 9 High School on redox reaction topic by using natural product praticum methods in chemistry learning. This research is a preexperimental study with a One Group Pretest-Posttest Design. The population and sample are taken all students of class X with a total number of students of 20 people. The collected data is processed from the results of the pretes-posttest. Data were analyzed using the formula t-test the research hypothesis and obtained tcount> t table (19.49> 2.10). The results show that the average posttest value was greater than the average value of the pretest, so it can be concluded that student learning outcomes provided with natural product practicum methods influence student learning outcomes.
