Abstract

Problem Based Learning and Discovery Learning are models that can increase motivation and learning outcomes of Macromedia Flash-based students on chemical equilibrium materials. The instruments used in this study are test instruments with a cognitive level of C3-C5 and non-test instruments of learning motivation questionnaires. This study aims to: 1) To determine the differences in learning outcomes with the PBL and DL models; and 2) To find a linear and significant relationship between motivatIon and student learning outcomes. The sample was 64 students of class XI MIPA 1 and MIPA 2 who were taken using random sampling techniques. Data analysis using a two-party t-test and a correlation test. The results: 1) There were differences in chemistry learning outcomes of students who were using the PBL and DL models. Where student learning outcomes obtained PBL model (18,219±2,268) and student learning outcomes using the DL model (16,438±2,327) with tvalue (3,101) > ttable (2.00) and a sig value (0.003)< sig(0.05). 2) There is a linear and significant correlation between motivation and student learning outcomes where in the PBL model obtained r count (0.773) > r table (0.349) and dl model obtained rcount (0.770) > r table (0.349) with sig(0.000) value < sig (0.05).

Abstract

The aim of this research is to find out whether there is an influence of the use of problem and video based learning models on student interest and learning outcomes. This research was conducted at SMA Negeri 14 Medan and the research population was all class. In the research, the pretest score was 34.85 and the posttest score was 80.28. Normality and homogeneity tests were carried out and the results showed normal distribution. In hypothesis testing using One Sample T-Test, a Sig.(2-Tailed) value of 0.002 was obtained. Therefore, a value of 0.002< α (0.05) means that the hypothesis is accepted, which shows that there is an influence of the use of problem-based learning models and videos on student learning outcomes in chemical bonding material. Meanwhile, for the results of student interest in learning, the average score obtained was 76.06 in the high category. This shows that there is an influence of the use of problem-based learning models and videos on students' learning interest in chemical bonding material.

Abstract

The aim of this research is to determine the improvement and differences in students' scientific literacy abilities taught using the Problem Based Learning and the Discovery Learning model assisted by animated video media on chemical equilibrium material. The sampling technique was carried out using purposive sampling, resulting in class XI IPA 5, totaling 34 students, as experimental class I and XI IPA 6, totaling 36 students, as experimental class II. In learning, the test instrument uses cognitive levels C4 to C6. The results of students' scientific literacy abilities taught using the Problem Based Learning model have increased with an average value from 47.05 to 82.94, as well as the results of students' scientific literacy abilities taught using the Discovery Learning model, namely with an average value of 44.17 to 79.94. Through hypothesis testing using the Independent Sample T-Test with the prerequisites of normality and homogeneity, a Sig (2-Tailed) value of 0.024 was obtained, so it can be concluded that Ha is accepted. The results of this research show that there are differences in the scientific literacy abilities of students taught using the Problem Based Learning and the Discovery Learning model assisted by animated video media on chemical equilibrium material.

Abstract

In the classroom, students have several barriers that affect learning outcomes and learning experiences. Generally, the obstacles that occur are the misconceptions experienced by students. Teachers' error causes many students to have misconceptions about the concept and lack practice questions related to the idea. This research was conducted to see and describe the students' misconceptions about understanding acids, bases and salts. This descriptive research uses test questions about acids, bases and salts and uses the CRI method to analyze data. The results show that students who lack understanding are 13.83%, good understanding 18.68%, and students with misconceptions 67.49%.

Abstract

Analysis of Student Learning Outcomes in View of Mathematical Ability and Ability Chemistry Class XI Science Students at Madrasah Aliyah Swasta (MAS) Proyek Univa Medan on Buffer Solution Material.The aim of this research is to determine the mathematical abilities and analytical abilities of students in class XI IPA Madrasah Aliyah Swasta (MAS) Proyek Univa Medan on Buffer Solutions material. This type of research is cause and effect research. The data collected was in the form of mathematical ability test instruments, chemical analysis ability tests and student learning outcomes tests based on Low Order Thinking Skills (LOTS) and High Order Thinking Skills (HOTS). The results of the analysis show that students have an average mathematical ability of 64.00 and an average student analytical ability of 63.24. Student chemistry learning outcomes in buffer solution material have an average of 47.00. Analysis of students' answer sheets on learning outcomes tests shows that students do not have good mathematical skills and analytical skills, shown by a percentage of 57%. This data also shows that students' difficulties with buffer solution material are due to students not understanding chemical concepts. DOI: 10.23960/jppk.v12.i3.23.13

Abstract

This study aims to develop teaching materials based on the IBL STEM model using the Wordwall application to improve students' critical thinking skills. The development model used refers to the ADDIE model with 30 students of the Chemistry Education Study Program, UNIMED as research subjects. The research instrument used an expert validation sheet and a test of students' critical thinking skills on stoichiometry material as many as 25 questions in the form of multiple choices. The results of the study indicate that teaching materials based on the IBL STEM model using the Wordwall application are feasible and effective in improving students' critical thinking skills in Stoichiometry learning. The feasibility is met qualitatively based on the assessment of material expert validators with an average total score of 4.36 (valid) and the assessment of media expert validators with an average total score of 4.32 (valid). Effectiveness is met based on the results of product implementation and evaluation results and is proven by statistical hypothesis testing (p < 0.05) with an average achievement of increasing students' critical thinking skills of 40.067 ± 9.318.

Abstract

In stoichiometry learning process, mostly educators focus on calculations. Students are not invited to think more critically about stoichiometry application in life. This constraint makes teachers have to develop new learning models, including Inquiry Based Learning (IBL) model, and Science, Technology, Engineering, Mathematics (STEM) based on chemical literacy. This study aims to develop general chemistry teaching materials on stoichiometry using IBL and STEM models based on chemical literacy that are feasible (valid) and capable of improving students' LOTS and HOTS abilities. The development model used is the ADDIE model, with research subjects of 34 students. The result shows that stoichiometry teaching materials using the IBL STEM model based on chemical literacy are valid (feasible) to be applied in learning with an average score of 4.42 for the material aspect and 4.55 for the design aspect. The developed teaching materials have been proven to significantly improve students’ LOTS and HOTS abilities.
