Abstract

This study aims to develop android-based learning media applications and determine the level of validity. This research was designed using the Plomp development model, which consists of 3 stages: the preliminary research stage, the development stage or prototyping, and the assessment stage. In this study, the authors limit the research carried out to the development stage or prototype, which produces prototype III. The development of this android-based application is expected to assist teachers in overcoming obstacles in making learning media and can be used as one of the learning media that can help students in learning, especially on the material of the periodic system of elements. Nine validators carried out the validation test of the learning media application: six content experts (Padang State University lecturers and teachers of SMAN 12 Padang) and three media experts (Lecturer of Engineering Padang State University). The data obtained from the validator was then analyzed using Aiken's V. The product validation test results had an index of 0.877 from content experts and 0.955 from media experts in the valid category. Thus, based on the validation test results, the Android-based learning media application on the developed periodic system material is valid.

Abstract

This study aims to develop a product in the form of an Android-based learning media application based on the mole concept material for class X SMA/MA that is valid and practical. The study uses the Plomp development research model, which consists of three steps: preliminary research, prototyping phase, and assessment phase. This research is limited to the prototyping phase for the practicality stage of the small group evaluation. Three chemistry lecturers carried out the product validity test at the Faculty of Mathematics and Natural Sciences, Padang State University, two Al-istiqamah High School chemistry teachers as material experts, and two lecturers of informatics engineering at Padang State University as media experts. Fifteen students and two chemistry teachers carried out the practicality test. The validity data analysis technique uses Aiken's V index. The validity test results showed that the Android-based learning media application developed belongs to the valid category with an average V value of 0.86 for material experts and an average V value of 0.93 for media experts. The practicality data analysis technique uses a percentage formula. The results of the practicality test in small groups are classified as "very practical," with a practicality percentage value of 90% for students' practicality and a practicality percentage value of 92% for teachers' practicality. Based on the results of the validation and practicality tests, it was found that applying android-based learning media to the mole concept material was valid and practical.

Abstract

Reaction Rate is material that high school students study in class XI MIPA in odd semesters. In this material, as much as 77.64% of SMAN 16 Padang class XI MIPA students have yet to achieve the minimum criteria set. It indicates that students have learning difficulties. Learning difficulties are failures in achieving learning goals characterized by low learning outcomes. This study aims to determine the percentage of students who experience learning difficulties for each indicator on the material reaction rate and determine the factors that cause learning difficulties experienced by students in terms of learning methods. This research is a type of descriptive research. The sample for this research was students in class XI MIPA 3 at SMAN 16 Padang in the 2022/2023 academic year, which consisted of 36 people. The research instruments used were two-tier multiple-choice diagnostic tests, questionnaires, and interviews. The data analysis used is descriptive, namely analyzing and providing an understanding of the data in the form of numbers so that an overview can be given in an orderly, concise, and clear manner. The results of this study stated that students of SMAN 16 Padang experienced learning difficulties in tar material with a high category. The highest difficulty level is found in the 3rd indicator (Explaining the effect of surface area on the rate of reaction), which is equal to 83.33%. Learning difficulties experienced by students are caused by ineffective learning methods, such as making study schedules and carrying them out, reading and taking notes, repeating material, concentrating, and doing assignments.

Abstract

Thermochemistry is a material high school students study in class XI MIPA in odd semesters. In this material, 83.69% of SMAN 13 Padang class XI MIPA students still need to achieve the minimum completeness criteria set. It indicates that students have learning difficulties. Learning difficulties are failures to attain learning goals characterized by low learning outcomes. This study aims to determine the percentage of students who experience learning difficulties for each indicator on thermochemistry material and determine the factors that cause learning difficulties experienced by students in terms of learning methods. This research is a type of descriptive research. The sample for this research was students in class XI MIPA 6 at SMAN 13 Padang in the 2022/2023 academic year, which consisted of 34 people. The research instrument was a diagnostic test with four-tier multiple-choice questionnaires and interviews. The data analysis used is descriptive, namely analyzing and providing an understanding of the data in the form of numbers so that an overview can be given in an orderly, concise, and transparent manner. The results of this study stated that students of SMAN 13 Padang had difficulty learning thermochemistry material in the high category. The highest difficulty level is found in the sixth indicator (determining the ∆H value of the reaction through a calorimeter experiment), which is 90.20%. Meanwhile, the lowest level of learning difficulty for students is found in the first indicator (explaining differences in systems and environments in chemical reactions), which equals 42.16%. Learning difficulties experienced by students are caused by ineffective learning methods, such as not making a study schedule and not carrying it out, not reading and not taking notes, not repeating material, not concentrating, and not doing assignments.
