This study aims to develop learning media in the form of gas steam stoves fueled by oil and describe the validity and effectiveness of the products being developed. This development and research are summarized in a study entitled the development of learning media in a gas-fired gas stove to increase students' curiosity in applied physics subjects. This study uses a media development research method known as Research and Development (R&D). From the research carried out, the following data were obtained: the results of media validation obtained very good categories, and validation test by media experts found very good category. In the curiosity test, which was initially limited to active students, the scores were very good. The results of the initial average curiosity test for the field test were obtained in the low category, and after the use of the media was tested again, and the average score was obtained in the very good category. It can be concluded that the use of an oil-fired gas steam stove in the form of a Pertamax stove as a learning medium can increase students' curiosity about learning applied physics material.
English is one of the primary subject that was taught in Electronic Engineering, Politeknik Negeri Bali, which includes speaking, writing and listening. Other than speaking, writing also become one of the most challenging subject in Electronic Engineering. To overcome the low writing skills of students and create pleasant learning atmosphere during the Covid 19 Pandemic, the authors want to try out learning method, namely Cooperative Learning Method with online media in the form of whatsapp. This research is a quantitative research with quasi experimental approach. The groups used in this study consist of two groups namely the experimental group using Whatsapp Cooperative Learning methods and the control grouos using the conventional method. The data collection technique in this study was in the form of a questionnaire and given to the students in both classes. From the data, it can be concluded that learning with the Whatsapp Cooperative Learning method is more effective to be used in teaching writing. It can be seen from the value of 2 of -2, 087 with Sig 0,037< 0,05 means that there is significant difference between the control class and the experimental class. This significant difference can be said as the result of the use of Whatsapp Cooperative Learning in class.
An appropriate learning method is a basic way for learners to be able to achieve maximum grades and the achievement of existing learning objectives. The Flipped Classroom method is one of the new methods in Indonesia which can be one of the preferred methods that can be applied in teaching English. Surely, a trial is required to measure its effectiveness. The current study has two purposes, the first one was to determine whether the Flipped Classroom learning method was able to effectively improve student learning outcomes, especially in English lectures. Then, secondly, the purpose was how to apply Flipped Classroom in the classroom. This research is quantitative descriptive research with a quasi-experimental approach, employing a "Pretest – Posttest Non-Equivalent Control Group Design". The current study involved 2 groups, namely the experimental group, taught using Flipped Classroom learning and the control group taught using conventional learning (without flipped Classroom design). It was found that the value of sig. Levene's test is 0.696 > 0.05, indicating that the data variance between the control class and the experimental class is homogeneous. Furthermore, the value of sig. (2-tailed) for the t-test, the value produces a value of 0.000 <0.05, then the decision-making in the t-test is to reject the Ho hypothesis and accept the Ha hypothesis. Thus, it can be interpreted that there is a significant difference between the average N-Gain scores of the control and experimental classes in English Engineering. It can be concluded that Flipped Classroom is effective in improving students' English skills in the topic of Describing Processes, as evidenced by the N-Gain value of 90, 91% which is included in the effective category. In other words, Flipped Classroom is effective to increase the students' scores in the class.
In an era where learning cannot be separated from technology, there are various Android-based applications that are very helpful, interesting and make learning adapt to the learner's time. Learning media is the learning source component that is able to stimulate students to study (Arsyad: 2005). In this paper the learning media is application. One such application is the Cake application. This application is a learning application that deserves to be tested because it has several advantages. One of the advantages of using learning applications is that there is no limited space and time for learners to learn. Learning is no longer limited to lecture rooms or lecture time. learning can be anytime and anywhere. The purpose of this research is to find out whether the Cake application has an effect on students who use it, especially in the speaking field, more specifically the pronunciation. This research is a type of quantitative research with a quasi-experimental approach. The design used is "Pretest – Posttest Non-Equivalent Control Group Design". The groups used in this study amounted to 2 groups, namely the experimental group using online learning and the control group using online learning as well but added with the application of Cake. In this study, according to determine the experimental class and control class, random assignment was done, namely, the selection was made randomly to choose the class. This research will provide benefits for teachers who want to try to apply the method so that it will be a reference later in the future.
