Knowledge of Physics Subject Teachers Toward Pedagogical Aspects in Public High Schools in Lhokseumawe City

In the education quality survey issued by the PISA (Program for International Student Assessment), Indonesia is ranked 72nd out of 77 countries. The Teacher Competency Test (UKG) results in Indonesia are still low and still far from being targeted by the government, especially in Aceh province Aceh at the national level is still heartbreaking by being the second lowest in Indonesia. Seeing the problems faced by education in Indonesia, to improve the quality of education, the quality of teachers must be improved first, one of which is by increasing the pedagogical competence of teachers. This study aims to know the pedagogical knowledge of physics teachers in SMA Negeri Lhokseumawe which includes aspects of learning planning, aspects of learning methods and aspects of learning evaluation. The research was conducted in the form of a survey with the population of this study was to take the entire physics subject teachers at SMA Negeri Lhokseumawe, totaling 7 (seven) schools with 28 physics teachers. The samples in this study were 3 schools that were taken by simple random sampling, namely 8 physics teachers at SMA Negeri 2 Lhokseumawe, 3 physics teachers at SMA Negeri 5 Lhokseumawe, and SMA Negeri 7 Lhokseumawe with 2 physics teachers. The results showed that the physics teacher's knowledge on the learning planning aspect was in the category of having good knowledge, meanwhile the physics teacher's knowledge on the learning method aspect already had a fairly good knowledge, while the physics teacher's knowledge on the learning evaluation aspect also had fairly good knowledge. So it can be concluded that physics teachers in the pedagogical aspect are in a fairly good category, meaning that most physics teachers already have a pretty good knowledge of pedagogical aspects

The Effect of Brain Based Learning on Improving Students Critical Thinking Ability and Self Regulated

This research is motivated by the low ability of mathematical critical thinking and Self Regulated Cimahi 10 Public Middle School students, so that a learning approach is needed to overcome these problems. The alternative approach applied is the Brain Based Learning Model approach.The objectives of this researcher are: 1) to examine students' mathematical critical thinking skills; 2) reviewing the Self Regulated attitude of students who obtain Brain Based Learning learning with students who have expository learning; 3) examine there is a positive correlation between Critical Thinking with Self Regulated students who obtain Brain Based Learning and expository learning. The population in this study was grade VII students of SMP Negeri 10 Cimahi. The samples in this study were class VII-B (Brain Based Learning) and class VII-D (expository). The instruments used in this study were the Critical Thinking test and the student's Self Regulated questionnaire. The test used is a subjective type test (description). The way to analyze data is with IBM SPSS Statistics 18.0 for Windows. The results showed that: 1) the mathematical critical thinking ability of students who obtained learning based on the Brain Based Learning approach was better than students who gained expository learning; 2) Self Regulated attitude, students who get Brain Based Learning are better than students who get expository approach learning; 3) there is no correlation between critical thinking with Self Regulated students who obtain Brain Based Learning and expository learning.

Application of Pop Up Book Media to optimize Science Learning Outcomes

Science Learning in MI Ma'arif Kumpulrejo 02 Salatiga has not used a variety of active and creative learning media. This causes students to be passive and the lack of student attention to the material delivered by the teacher. Evidenced by the low learning outcomes of students who have not yet reached the KKM determined by the school 65. The purpose of this study was to determine the increase in science learning outcomes through Pop-Up book media in class IV MI Ma'arif Kumpulrejo 02 Salatiga. This research is a classroom action research conducted in three cycles, namely Cycle I, Cycle II, and Cycle III. Each cycle consists of four stages, namely planning, implementing, observing, and reflecting. The subjects of this study were class IV students, totaling 28 students. Data collection methods are interviews, observation, and documentation. The results of this study indicate that the application of Pop-Up book media can improve science learning outcomes in fourth grade students of MI Ma'arif Kumpulrejo 02 Salatiga. Improvement of students who have finished learning from Cycle I to Cycle II 25% and Cycle II to Cycle III 21.42%. Completeness of student learning outcomes in Cycle I 39.29% of students completing study with an average value of 56.07. In Cycle II 64.29% of students completed study with an average value of 68.92, and Cycle III 85.71% of students completed study with an average value of 80.17.

Developing Student Worksheets (LKPD) based on Problem Based Instruction on Environmental Pollution Material

This study aims to reveal (1) how the characteristics of LKPD based on Problem Based Instruction models on environmental pollution material (2) how the feasibility of LKPD based on Problem Based Instruction models on environmental pollution material (3) how practicality of LKPD based on Problem Based Instruction models on environmental pollution material. Research refers to the Borg and Gall development model to the seventh stage, namely potential and problems, data collection, product design, design validation, design revision, product testing, product revision. The research instruments used in data collection were interviews, observation, and questionnaires. The data obtained were then analyzed by quantitative descriptive analysis. The characteristics of LKPD teaching materials developed using the Problem Based Instruction model on environmental pollution materials are arranged systematically, interestingly, and clearly. Students can learn independently; the developed LKPD does not depend on other media, and students can interact directly with the environment. Based on the feasibility trial LKPD is in the "Very feasible" category. Material experts with grades X≥ 33 categories are very feasible, media experts X≥ 45 categories are very feasible, linguists X≥ 18 categories are very feasible, expert practitioners X≥ 42 categories are very feasible, and students' responses X≥ 33 categories are efficient. The results obtained can be concluded that the developed LKPD meets the very feasible category, so it is suitable for use.

Comparison of Learning Outcomes Inquiry Learning Model With Cooperative Learning Model Type Number Head Together (NHT) Learning In Natural Sciences Class V In Public Elementary School 66 Bengkulu City

Although many have raised the Inquiry learning model and the Number Head Together (NHT) learning model, there is no research on comparison of the two models in natural science subjects. This study aims to determine whether the learning outcomes of the 5th grade science students taught using the Inquiry Learning Model is better than using the Cooperative Learning Model Number Head Together (NHT) type in SDNegeri 66 Bengkulu City. This study used two groups, namely class 5A with 31 people as the experimental group and class 5B with 31 people as the control group. This research variable consists of independent variables namely Inquiry learning model and Number Head Together (NHT) learning model while the dependent variable is the science learning outcomes. This type of research is quantitative research with Nonequivalent Control Group Design approach. Data collection techniques using observation and multiple choice test questions. Data analysis techniques using the t test. Based on the results of the study found in the posttest results of class 5A students who use Inquiry Learning Model in the medium and high categories as many as 31 students (93%) get grades of 60 to 100 while the learning outcomes of class 5B that use Cooperative Learning Models Type Number Head Together ( NHT) as many as 31 students (81%) get a value of 50 to 90. It can also be proven by the results of the t test calculation that is tcount of 4.352 and the value of the table for df = 60 with a significance level of 5% is 2,000. From the analysis it was found that tcount is greater than ttable (4.352> 2,000). The results showed that the learning outcomes of Natural Sciences 5th grade students who were taught using the Inquiry Learning Model were better than using the Cooperative Learning Model Number Head Together (NHT) type at SDN 66 Kota Bengkulu.
