Article historyConcept attainment models are learning models that can bring students to analytical thinking, and their phases are indicators of analytical thinking. This study aims to determine the application of student worksheets based on the concept of attainment models on the topic of the interaction of living things with their environment to improve analytical thinking skills. This research is a quasiexperimental study with One Group Pretest-Posttest research design. The sample is students of class VII-G of SMP N 1 Arosbaya, sampling technique with a purposive sampling technique. Data collection techniques using analytical thinking skills tests, and then the test results were analyzed statistically. The results showed that the N-Gain value was 0.46 (medium). Paired t-test shows the significance value of 0.000, if sig < 0.05 then H0 is rejected (-t count < t table < t count = -14.020 < 2.052 < 14.020). Based on the N-Gain Score and the comparison of the critical values of t table and t count, there is an increase in students' analytical thinking skills after learning using student worksheets based on the concept attainment models. Analytical thinking skills will facilitate students in the process of solving problems and drawing conclusions.This is an open access article under the CC-BY-SA license.
The type of research applied in this research is Research and Development. The development model used is Dick and Carrey. The purpose of this research and development is to design an Atlas and apply it to train the students' scientific reasoning abilities. Atlas is a teaching materials developed and applied to high school / vocational / MA level students. The sample chosen for the implementation of the Atlas of teaching materials was grade X of VOCATIONAL Health Yannas Husada Bangkalan students. The application of plants as natural indicators of acid-base tests is the material presented in the developed Atlas. Plants selected as indicators are tested first to be presented in the Atlas. Atlas is a teaching material that can convey information related to the use of natural indicators of the acid-base test to train the students' scientific reasoning skills. The four indicators of scientific reasoning that are trained are Theoretical Reasoning, Proportional Reasoning, Probabilistic Reasoning, and Correlational Reasoning. The data shows the students' scientific reasoning ability on the post-test results, as many as 20% of students are on the high criteria, 60% are moderate criteria, and 20% are still on the low criteria from the post-test results. The post-test result data is quite increased when compared to the pretet results, which 100% of students are in the low criteria.
