Abstract

Understanding is one of the bases for developing learning models, with an emphasis on indicators of learning understanding. One alternative when learning can enable increased understanding of concepts by using the CTL learning model. The purpose of this study was to determine the effect of CTL on increasing the ability to understand biology students' concepts. The type of research used was a quasi-experimental design in the form of a nonequivalent control group design. The quasi-experimental group has a control group, but cannot fully function to control external variables that affect the implementation of the experimental group. The research design uses the pretest method before the lesson starts, then is given treatment using the CTL learning model, and ends with a posttest to measure differences in the level of students' conceptual understanding abilities at each meeting. The form of this research is quantitative. The results showed that there was an effect of using the Contextual Teaching and Learning (CTL) learning model on students' understanding of concepts with a pretest control class score of 65 and a posttest of 75. Meanwhile, the pretest and posttest experimental class scores were 80

Abstract

A person's success in mastering a material is caused by the belief he has, because it is this belief that will cause a person to behave in such a way that the belief will materialize. One source of belief is the level of self-confidence. ability (self-efficacy). The Scientific Critical Thinking (SCT) model is a model that can be applied to material on the human respiratory system in class A1 and A2 biology lessons at Lancang Kuning University. This study aims to determine critical thinking skills, communication skills and self-efficacy of biology students in the application of the SCT model to the material on the respiratory system. The method in this study was a quasi-experimental study with a post-test nonequivalent control group design. The sample of this study were students in class A1 biology (experimental class) and class A2 biology (control class). Retrieval of data in research using test and non-test techniques. Data analysis techniques used in this study are descriptive and inferential. The results showed that (1) there was an increase in critical thinking skills (2) an increase in communication skills and (3) an increase in self-efficacy. The experimental class was better than the control class in training biology students' critical thinking skills, communication skills, and self-efficacy in learning material on the human respiratory system.

Abstract

This research was conducted to determine the use of the Project Based Learning (PJBL) learning model on the motivation of biology education students at the Muhammadiya Sorong Education University. This research was carried out in semester 4 in classes 4.1 and 4.2 at the Muhammadiyah University of Education, Sorong, academic year 2022/2023. The research design used was Quasi Experiment Pretest Posttest Control Group Design. In Quasi Experiment Pretest Posttest Control Group Design, the experimental and control groups are selected randomly. Data collection was carried out through pretest, posttest and observation sheets. Based on the results of research in the control class, the average overall score of the control class motivation indicators was 2.35, including in the medium category with a percentage of 57.47%. Meanwhile, in the experimental class there was a significant difference between the class given conventional learning and the class given Project Based Learning (PJBL). Student motivation appears to have increased. The questionnaire value of 2.51 is included in the high category with a percentage of 60.13%. Thus, learning with the Project Based Learning (PJBL) model can be said to increase the learning motivation of 4th semester students in the Biology Education Department at the Muhammadiyah Sorong University of Education.

Abstract

Hyperlipidemia is a condition of high levels of lipids in the blood. Hyperlipidemia is a major factor causing non-communicable diseases such as DMT2 and stroke. Purslane is a plant that contains PUFA which is hypolipidemic. The purpose of this study was to test the effectiveness of giving purslane plant fatty acid extracts in reducing triglyceride levels in obese rats induced by a high-fat and high-calorie diet. There were five treatments in this study, namely P1 negative control (no treatment), P2 positive control (by administering gemfibrozil), P3 (100 mg/kg BW of purslane fatty acid extract), P4 (200 mg/kg BW of purslane fatty acid extract), P5 (300 mg/kg BW of purslane fatty acid extract). The test animals used were male rats strain Ratus norvegitus, male, initial body weight ± 200 grams with final body weight ≥ 10% of initial weight. This research is True-Eksperimental Research using a Control Group Pretest-Posttest Design with the RAL experimental design. The data obtained were analyzed statistically using tests Quade's Rank Analysis of Covariance. The results showed that the purslane plant fatty acid extract could reduce triglyceride levels. In this study, a dose of 300 mg/kg BW was the best dose for reducing triglyceride levels in obese rats.

Abstract

At English Education Department of Education and Vocational Studies Faculty of Universitas Lancang Kuning, it was found that the students had low speaking skills. One of the factors is the students’ hesitation in making mistakes, especially mistakes in grammar. It was Classroom Action Research (CAR). The aimed of this research was to improve the students’ low speaking skills by using TENANT (Teaching English with Natural Acting and Natural Talking) and Real Object. This research had been carried out since February until April 2022. It had three cycles and five meetings within it. There were 24 students all of them who were taught to speak English by using TENANT and Real Object. It was found that there was improvement of the students’ speaking skills under the use of TENANT and Real Object which were based on the students’ speaking based score with their scores from cycle I, II, and cycle III. In conclusion, TENANT and Real Object can help the students to improve their speaking skills. This finding implies that the use of TENANT and Real Object can be used to enhance the students’ speaking skill in English speaking class.
