And Function

One of the problems faced in education in the 21st century is the critical thinking skills of students who are still considered lacking. One of the learning tools that need to be improved to help improve students' critical thinking skills is the Student Worksheet (LKPD). This study aims to describe the effectiveness of LKPD on the concept of Structure and Function of Plant Tissue Based on Critical Thinking Skills. The validation subjects were 3 experts, individual test subjects were 3 high school class XI students and small group test subjects were 6 class XI high school students. This type of research is development research to produce valid, practical, and effective products. The results showed that the effectiveness of LKPD expectations based on the assessment of students' critical thinking skills in working on LKPD had both categories (including interpretation, analysis, inference, and explanation) and very good categories (including self-regulation). Interpersonal skills (collaborating) and intrapersonal skills (meticulous) students have very good categories.

<p>The purpose of this study was to determine the profile of critical thinking skills of senior high school students. The paper-based essay questions and the questionnaires were used as the instruments to measure critical thinking skills in daily chemistry problems, which is based on Facione’s critical thinking aspects included interpretation, analysis, evaluation, inference, explanation, and self-regulation. The research was conducted in one of government senior high school in Central Java, Indonesia. The descriptive-qualitative method was used for the research method. The qualitative approach was used to analyze the data by using essay questions and questionnaires. The criteria for critical thinking skills were categorized as null, low, medium, and high. The result showed that most of the students have weak or low skill in critical thinking, especially in analysis, evaluation, explanation, and self-regulation whether their skill of interpretation and inference are medium. This finding can be used to develop a new strategy in teaching chemistry related to critical thinking skill.</p><p> </p>

In today's digital environment, using technology in learning is a requirement for staying relevant to the needs of the twenty-first century. The goal of this study is to develop learning tools that combine Project-based learning (PjBL) with STEM-based e-learning to assist students enhance their creative thinking skills and self-regulation. This study is a quantitative descriptive study using a one-shot case study research design and a research sample of 25 high school students in class for the academic year 2020/2021. The N-Gain score is used to collect data using test and non-test instruments before and after treatment to assess if there is an improvement in learning outcomes. All indicators of critical thinking skills and self-regulation increased as a result of the study. On the fluency indicator, the creative thinking skills indicator received the highest score of 0.86, while self-regulation received the biggest rise on the organizing and transforming indicator with a score of 0.83. The average increase in critical thinking skills is 73.66 percent, and the average rise in self-regulation is 79.42 percent, both of which are high

This research aims to analyze the critical-thinking skill of the junior high school student in Mojokerto. This research describes students geoscience conception by using question instruments related to students' critical-thinking skills. The method that used in this research was pre-experimental design with one-shot case study design and descriptive quantitative approach. The test is done online via google form. The question instrument contains 20 questions related to geoscience concept, disasters, and mitigation materials that have been validated by a validator. This research involved 107 students who were on the 7th grade of junior high school in Mojokerto. The results showed that the analysis related to geoscience knowledge of students got an average of 48.79% which was included as very low category, while the critical-thinking skills got 43% on the interpretation indicator, 52% analysis, 79% evaluation, 40% inferential, explanation. 54%, and self regulation 40% with an average critical-thinking skills of 51% which concluded in the very low category. These critical-thinking skills must be built, especially in geoscience conceptl. The accuracy of the analysis of critical-thinking skills in this research only shows the results in the Mojokerto area.

An effective teaching method for cultivating students' critical thinking skills of junior high school students in Indonesia is very necessary as their critical thinking ability is still low. This research is a descriptive study which aimed at cultivating learners' critical thinking by using short-videos since it is believed that technology can motivate the students, increase their interest, engage them to the lesson matter, provide effective learning activities, and demand them to think critically and creatively. The subject in this study were 130 Junior High School students (SMP Negeri 1 Sedayu, Yogyakarta) grade IX. The students were homogeny in term of age, economic, and social background as well as in English language score. Facione's critical thinking rubrics were used to indicate the level of students' critical thinking such as their interpretation, analysis, evaluation, inference, explanation, and self-regulation skill of short video. The average score of all item in pre-test critical thinking skills was at fair level with the score 9 out of 20. The results indicate the students' interpretation skills were fair with the score of 9 out of 20; analytical skill was 12; evaluation skill was 9 out of 20; self-regulation was in fair criterion with the score of 5 out of 10 and good level of explanatory's skill with the score 6 out of 10, while 12 for inferences. It can be concluded that the critical thinking skill of the students of Junior High School was still unsatisfactory as most of them can only reach fair levels. The use of video cannot improve all critical thinking skills. It is recommended more practices for the students.

One of the learning tools that need to be developed, so that the objectives of the 2013 curriculum are achieved, one of which is the Student Worksheet. The Student Worksheet is one of the learning media that can help students to be more active in constructing their knowledge according to the demands of the curriculum. Critical thinking is the ability to give reasons in an organized manner, and evaluate the quality of a reason systematically. The ability to think critically can help the problem-solving process, simplify work, and be able to determine the relationship of something to another more accurately. This study aims to produce high school Biology worksheets based on valid critical thinking skills on Ecosystem material. This development uses the Tessmer design, which consists of (1) self-evaluation stages, (2) expert reviews, and (3) individual tests. Validation was carried out by 3 experts (2 lecturers and 1 teacher). The results showed that the product validity has a valid category, with an overall average of 3.58 declared valid, and based on expert tests it has a content practicality category with an average of 3.85, declared good.

In 21st century learning, critical thinking skills are the main choice that must be mastered by students. This study aims to determine the effectiveness of local wisdom-based science teaching materials in improving junior high school students’ critical thinking skills. Most science teachers still apply teacher-centered learning, so students tend to be passive. This type of research is quasi-experimental with a pretest-posttest control group design. The study was conducted in the even semester of the 2019/2020 school year. The subjects of the research were grade VII students. Data collection techniques and instruments in the form of tests that include indicators of critical thinking skills. Data analysis used homogeneity test, Kolmogorov Smirnov normality test, independent sample t-test, and n-gain score. The results of the independent sample t-test are sig. (2-tailed) = 0,000<sig. α = 0.05. Students’ critical thinking skills in the experimental class were higher (N-gain score = 39.09%) than in the control class (N-gain score = 12.03%). Based on the study results, it can be concluded that there is a significant influence on the application of local wisdom-based teaching materials in improving the critical thinking skills of middle school students in the moderate category.
