Guided Discovery in Genetic Learning: Implementation and Impact on Higher-Level Thinking Skills

The challenges of 21st century education today require students to have high-level thinking skills given the many dynamic changes that occur in the field of education. High-level thinking skills are divided into several aspects including critical, creative and collaborative thinking skills. One of the appropriate learning model to improve critical thinking in students is the guided discovery model .The purpose of this study was to determine the implementation of guided discovery. Model in learning genetics to increase higher thinking skills of students of SMAN 1 Lawang which include critical, creative, and collaborative thinking skills. This quasi-experiment was carried out by means of a pre-test and post-test control group design. The sample involved in this study is student of class XII IPA 3 (eksperiment class and student of class XII IPA 4 obtained by purposive sampling techniqueThe results showed that there are differences in the critical, creative and collaborative thinking skills of students who studied with the guided discovery model with a level of significance <0.05.

Peningkatan Minat dan Hasil Belajar IPA Melalui Metode Eksperimen Pada Materi Rangkaian Listrik di Kelas IX SMPN 1 Percut Sei Tuan

This research was conducted on the basis of the results of observations of the science learning process in class, where the interests and learning outcomes of science learning, especially in class IX-3 have not progressed as expected. Low learning interest causes the students' daily test scores to show disappointing results, where the results have not reached the expected Minimum Completeness Criteria standard. The average value of science learning outcomes in grades IX -3 at SMP Percut Sei Tuan only reached 55.1. To overcome this problem, it is necessary to improve by conducting Classroom Action Research. Action research was conducted in class IX-3 SMP Negeri 1 Percut Sei Tuan Jln.Besar Tembung Gang Pendidikan, Percut Sei Tuan District, Deli Serdang Regency. The research lasted for 3 months in the odd semester of the 2017/2018 school year which was carried out in 2 cycles by suggesting 4 stages for each cycle, namely: the planning, implementation, observation and reflection stages. The data obtained from each cycle were analyzed using qualitative and quantitative data analysis. This can be seen from the results of the average observation of student interest in learning science per individual, where students with very high interest in learning are 3.13%, students with high interest categories are 46.87%, students who are interested in learning are 34.37% and students with low interest in learning are 15.63%. Overall, the percentage of interest in learning has not reached 75%. Then continued with the second cycle, it was obtained that the observation interest in learning had increased. This was seen from the results of the average observation of student interest in learning science per individual that had increased. where students with very high interest in learning categories 25% of students with high interest categories 66.67%, students with sufficient interest in learning categories 8.33% overall the percentage of interest in learning has reached above 75%. The results of the first cycle test, there were 24 students (66.67%) who had achieved mastery learning while 12 students (33.33%) had not yet achieved mastery learning. After it is known that there is an increase, it is continued to provide action in cycle II. The results of the second cycle test had increased, the number of students who completed was very large, namely from 36 students, it turned out that 33 students (91.67%) had achieved completeness in learning, only 3 students (8.33%) had not achieved completeness in study.

Analisis Kesalahan Mahasiswa pada Penyelesaian Soal Mata Kuliah Anatomi & Fisiologi Manusia

Human Anatomy and Physiology is one of the courses for biology students that is abstract so that not a few students have difficulty studying it. Errors in answering questions can be used as clues to determine the student's mastery of material. This study aims to determine student errors in solving problems in the Human Anatomy & Physiology course. This research is a qualitative descriptive study. The data collection method used is the test method. The subjects in this study were biology education students in semester V of the Nineteenth November University Kolaka Academic Year 2019/2020 who took Human Anatomy and Physiology courses. The instrument used in this study was the UAS test questions in the Human Anatomy & Physiology course. The results of the analysis showed that the most difficult questions for students to understand were questions on the function of the eye parts where the points obtained by nine students were only 2 points with the percentage of correct answers only 2%. While the questions on autoimmune disease material got the most correct percentage of answers where the number of points was nine students, namely 31 with a percentage of 34%. From the research results, it can be concluded that by analyzing student errors in answering questions, it can be seen what material is difficult for students to understand so that it can help lecturers to improve the learning process in the following semester.

Penggunaan Model Pembelajaran Collaborative Creativity Untuk Meningkatkan Kemampuan Berpikir Kreatif Siswa Pada Materi Pencemaran Lingkungan

The 2013 curriculum applies a scientific approach in the learning proses, therefore students are expected to have higher order thinking skills, one of which is creative thinking. Students' creative thinking skills can be trained by implementing student-centered learning. The purpose of this study was to analyze the using of collaborative creativity learning model on students' creative thinking abilities on the topic of environmental pollution. The method used in this study was a quasi-experiment with a pre-experimental research type and one group pretest-posttest research design. The subjects in this study was class X science 8 Senior High School in Bandung. Creative thinking abilities measured in this study include four aspects: fluency, flexibility, originality, and elaboration. Data of students' creative thinking skills were obtained from the pretest and posttest scores. Based on the results of data processing, the creative thinking ability of students has increased after using collaborative creativity learning model with a gain index value of 0.31 in the medium category. This shows that the use of collaborative creativity learning model can improve students' creative thinking ability on the topic of environmental pollution. The benefit of this research is that the Collaborative creativity learning model can be used as a reference for learning in class.

Pengaruh Laboratorium Virtual Berbasis Problem Solving Terhadap Kemampuan Berpikir Kritis

The availability of facilities and infrastructure in learning Cell and molecular biology courses is needed to support the achievement of learning objectives. Based on the results of observations in the Imelda University, Pharmacy Department, the lack of implementation due to the lack of facilities and infrastructure that support the practicum causes a lack of improvement in students' critical thinking skills. The ability to think critically is the main factor affecting student understanding. In this case, the media that can support this is a problem solving-based virtual laboratory to encourage students' critical thinking skills.
