Abstract

One of Indonesia's local wisdom is Timba Nyale. The Timba Nyale tradition is held every year in March-April, where the people of Sumba flock to the coast while waiting for the appearance of Nyale. This research aims to understand the meaning of Timba Nyale cultural studies and analyze the importance of Science in Nyale to be used as authentic Science learning material. This research was conducted in Buku Bani Village, Ate Dalo Village, Kodi District, Southwest Sumba Regency, East Nusa Tenggara. The method used is a qualitative method using grounded theory. Data collection was done through interviews, observation, documentation, and literature study. The results showed that Nyale has a significant meaning which is a marker for the success or failure of the harvest for the people of Sumba. Nyale in the Sumba tradition also has scientific values, including the importance of preservation and maintaining the conservation of species called Nyale. Analysis of learning outcomes in Animal Anatomy and Physiology courses in one of the private universities in Sumba shows that Nyale can be studied in the practicum of animal anatomy and physiology courses.

Abstract

Student learning outcomes in science subjects often experience problems such as low learning outcomes due to the application of conventional learning models. This makes students passive and learning boring and non-contextual. To overcome this problem, one model that can be used is the experimental model, which is expected to improve student learning outcomes by actively involving them in the learning process directly. The purpose of this study was to determine the effect of the experimental method on student learning outcomes on the material on changes in the state of matter in class VII of junior high school. The type of research used was quasi-experimental research with a pretest-posttest control group design. There were 27 students in the study, with 14 students in the experimental class and 13 students in the control class. The research instrument was a multiple-choice test consisting of 20 questions that had been tested for validity and reliability. Data collection techniques were carried out through pretest and posttest, while data analysis used the Mann-Whitney U Test non-parametric test with the help of SPSS version 16.0. The results showed a significant difference in learning outcomes between the experimental class and the control class with a significance value of 0.000 < 0.05. This proves that the application of the experimental method has an effect on student learning outcomes in class VII on the material on changes in the state of matter.

Abstract

Critical thinking skills are essential 21st-century competencies that need to be developed in science education. This study aims to analyze the critical thinking skills of grade VIII students in a junior high school on human respiratory system topics. This research employed a qualitative descriptive method involving 27 students. The research instruments consisted of an essay test developed based on Ennis's critical thinking indicators (basic clarification, bases for a decision, inference, advanced clarification, and strategies and tactics) as well as semi-structured interviews with six students selected through purposive sampling. Data analysis was conducted using the Miles and Huberman model, which includes data reduction, data display, and drawing conclusions. The results showed that the majority of students possessed critical thinking skills in the low category: 22 students (81.48%) were in the low category, 3 students (11.11%) in the moderate category, and 2 students (7.41%) in the high category. These findings emphasize the need for implementing innovative learning strategies to enhance students' critical thinking skills in science learning.
