Abstract

The teacher is a party that has great responsibility in achieving learning goals. One of the competencies that must be possessed by teachers is pedagogical competence. This research was conducted with the aim of uncovering the problems of teacher pedagogical competence in learning, as well as alternative solutions that can be done to overcome these problems. The method used in this research is literature analysis. The literature is a scientific article that discusses the problems of teacher pedagogical competence. The results of the study show that the problem of teacher pedagogic competence is the lack of the teacher's ability to plan, implement and evaluate the learning that is carried out. Planning, implementation and evaluation are related to all aspects of learning, be it objectives, materials, methods or evaluation. Alternative solutions that can be implemented are increasing teacher awareness of the importance of self-motivation, maximizing the function of the LPTK (Educational Personnel Providing Institution) in preparing competent teacher candidates and maximizing the function of teacher competency development programs.

Abstract

Based on the results of preliminary observations at SMA Negeri 1 Jereweh, West Sumbawa Regency, it shows that students are less involved in the learning process and students tend to be passive. One of the factors that causes students to be less involved in learning is because the learning model and learning approach applied by the teacher are less varied. Therefore, research has been conducted on the effect of the Guided Inquiry learning model on problem-solving abilities and cognitive learning outcomes of Class XI Biology students at SMA Negeri 1 Jereweh. The purpose of this study was to examine whether there was an effect of the Guided Inquiry learning model on problem solving abilities and cognitive learning outcomes of class XI students of SMA Negeri 1 Jereweh. The type of research used in this research is Quasi Experiment. The research design in this research was pre-test and post-test, and the research samples were 19 students from class XI IPA 1 as the experimental class, and 18 students from class XI IPA 2 as the control class. Data collection uses observation sheets to determine students' problem solving abilities and test sheets to determine students' cognitive learning outcomes. Based on the results of data analysis, the average value of the control class for problem solving ability was 82.5% in the high category, and the average value of the experimental class for problem solving ability was 90.62% in the very high category. The average value for the cognitive learning outcomes of the control class was 77.2, while the average value for the experimental class was 85.7. Testing the hypothesis using t-test analysis (t-test) at a significant level of 5%, obtained a tcount of 6.248 > ttable value of 1.684, so it can be concluded that there is an influence of the Guided Inquiry learning model on cognitive learning outcomes of class XI students of SMA Negeri 1 Jereweh.

Abstract

This study aims to find out how the Index Card Match learning method influences the motivation and cognitive learning outcomes of students at SMP Negeri 4 Jonggat, Central Lombok Regency. Learning by using the Index Card Match learning method is expected to have students highly motivated in learning to obtain high learning outcomes as well. Through this application it can also make it easier for teachers to improve ways of thinking and increase student involvement in the teaching and learning process. The type of research used in this research is a quasi-experimental (quasi-experimental), this design has a control group, but it does not fully function to control the variables that affect the implementation of the experiment. The experimental class received treatment using the Index Card Match learning method, while the control class used the conventional method. To obtain the necessary data, this study used the t-test analysis technique. From the results of the study, based on the results of the hypothesis testing of the experimental class and the control class using the t-test, the tcount was 0.13 and the ttable was 2.12. This means that the tcount value is smaller than the ttable value or 0.13 <2.12. This shows that Ha is rejected and H0 is accepted, so there is an influence of the Index Card Match learning method on students' motivation and cognitive learning outcomes.
