Abstract

The development of scientific fields is possible through communication between researchers. This communication can be established with a medium called the Scientific Journal. Through the media, each researcher searches for articles that have been researched on the same topic. So that they will easily update or develop the topic. This method is known as the bibliometric analysis method. Therefore this study aims to carry out the same analysis on the virtual lab theme. This is important in learning development, especially in science learning. The data obtained was in the form of many articles from the SCOPUS database, which several criteria had previously defined to capture them. These criteria are related to the year of publication, keywords and language selection. The application used in this study is the VOS Viewers application. The results show that research related to virtual labs in science learning is still very possible considering many limited lab facilities in some schools. However, it should be noted that virtual labs cannot replace traditional laboratories because traditional laboratories can give students hands-on practical experience. It is better if the virtual lab is considered as a supplementary to science learning

Abstract

Learning motivation is an important aspect that can encourage students to carry out learning. Self-Determination Theory assumes that individuals have basic psychological needs to develop and learn which include competence, relatedness, and autonomy. This study aims to characterize student learning experiences in the affective aspect (motivation) related to learning outcomes (Theory and Practicum). The researchers used the descriptive correlation research design to describe students' motivation profiles and provide an overview of the relationship between chemistry learning motivation and learning outcomes in Biochemistry courses (Theory and Practicum). The data was collected using the AMS-Chemistry instrument, which was analyzed through descriptive statistics and Pearson correlation analysis. The AMS-Chemistry consists of a motivation subscale, extrinsic motivation, and intrinsic motivation, which are spread into 28 statements, which was validated and reliable. The research subjects used 40 students from a total population of 118 people. Overall, the motivation profile to learn chemistry in science education students on the amotivation subscale tends to disagree, extrinsic motivation with a tendency to agree, and the subscale of intrinsic motivation with a tendency to strongly agree. Student learning outcomes in Biochemistry (Theory) courses have a significant relationship with extrinsic motivation (external regulation, introjected regulation, identified regulation) and intrinsic motivation (to know, to experience), while in Biochemistry (Practicum) has a significant relationship with motivation extrinsic (identified regulation) and intrinsic motivation (to know, to accomplish, to experience). This finding is a reflection that can be used as a reference in developing further learning.

Abstract

Laboratory skills are an important aspect of natural sciences in schools and higher education, often linked to psychomotor aspects of learning. Several studies have developed several methods that can be used to evaluate laboratory skills, for example, the use of observation sheets equipped with rubrics. However, often using this method requires a longer learning time. Therefore, there is a need for research that examines how to evaluate students' basic laboratory skills. This research aims to analyze students' basic laboratory skills using pictorial-based instruments. This research method uses descriptive qualitative. This instrument is equipped with pictures that provide visualization. The basic laboratory skills are focused on experiments on making standard solutions from solids, making standard solutions from concentrated solutions, and acid-base titrations. Based on the analysis, it was found that the basic laboratory skills of science students in the experiment of making standard solutions from solids contained six basic skills, including selecting tools, weighing solids, transferring solids into a beaker, putting them in a volumetric flask, marking the solution, reading the meniscus mark. In the experiment of making a standard solution, there are five basic skills, namely selecting tools, taking the stock solution, transferring it into a volumetric flask, marking the solution, and reading the meniscus mark. The titration experiment consists of 8 skills, including selecting equipment, taking the analyte solution, taking the titrant solution, adding a titration indicator, using the titration technique, observing the endpoint of the titration, reading the meniscus, and calculating the solution's concentration.

Abstract

Understanding chemical concepts as a whole show that students can connect three levels of chemical representation. The three levels in chemical representation are related and reflected in students' mental models. A teacher must know the student's mental model as a reflection of learning. This research aims to develop an instrument for students' mental models on voltaic cell submaterials using the prediction-observation-explanation (TDM-POE) mental model diagnostic test. The method used in this research is the research and development method using the Analysis, Design, Develop, Implement, and Evaluate (ADDIE) development model. The instrument was validated by five validators consisting of four lecturers in the Department of Chemistry Education and one chemistry teacher at school. Validity is determined by content validity response. Then, the instrument was tested on class XII students who had received learning about voltaic cells. The instrument consists of four questions for four concepts: voltaic cell construction, calculating standard cell potential values, voltaic cells in alkaline batteries, and corrosion phenomena. Each question consists of 3 stages, namely, the first stage contains questions about predicting phenomena (predict), the second stage contains video or image observations (observe), and the third stage contains detailed explanations (explanation). The validation results show that the validity of the TDM-POE instrument obtained a score of 0.99, which is categorized as valid. So, the TDM-POE instrument can be used to understand chemical concepts.
