Abstract

Periodical properties of elements are not a new topic for students in science education department for they have studied this topic previously in senior high school and in General Chemistry course. However, teaching experiences for the past two years in Basic Inorganic Chemistry course revealed that many students still failed to master the expected learning outcomes for this topic. Therefore, this explorative study was conducted to figure out what kind of difficulty that students perceived in learning this topic. One hundred and twelve students in science education department of Universitas Negeri Padang enrolled in Basic Inorganic Chemistry course in the academic year of 2017/2018 were involved as subjects in this study, and data of students? perceived learning difficulties were collected with a questionnaire. Data were analyzed with descriptive statistics technique to map out our findings which will become the fundamental consideration in discussing attempts to overcome students? perceived learning difficulties. Our findings revealed that the sources of students? perceived difficulty came from several factors, namely: the characteristic of content, personal learning style, condition of classroom learning, availability of relevant learning resources and previous learning experiences. Based on these findings, attempts for better learning of periodical properties of elements were suggested.

Abstract

Socialization and training of the use of learning media based on learning management system (LMS) with moodle for junior high school teachers at Methodist 8 Medan aims to improve teachers' knowledge and skills in integrating Information Technology and Communication (ICT) into interactive, interesting and fun online learning. Moodle is a software application produced for dynamic learning activities based on technology, internet and websites. The methods that used for implementing this Community Partnership Program are socialization and training which begin with preliminary observations, analysis of learning problems and the needs of teachers and students. The next stage is the preparation of activities both from the partners and the team. The third and fourth stages are socialization and training on the use of learning media based on LMS by using the Moodle features. The result of this partnership program is that teaching materials such as power point presentation, learning videos, assignments and quizzes/student worksheets have been created and uploaded by utilizing the features in Moodle.

Abstract

This study aims to describe the effectiveness and method of lectures that took place during the Covid-19 pandemic. The Covid-19 pandemic requires all aspects of life to adapt, including in the field of education. This research is a descriptive quantitative study with a simple survey method using an instrument in the form of a google form which was designed to find out what students and lecturers think about lectures during the Covid-19 pandemic. The opinion in question was an opinion about the method or media used as well as the difficulties faced in the implementation of online lectures during the pandemic. This study used a purposive sampling technique, namely 5 universities in Indonesia consisting of 200 lecturers and 200 students. All respondents were asked to fill out an online questionnaire in the form of a google form designed to find out the methods or media used in lectures as well as the difficulties faced in using the media. The survey results show that the combination of media that was mostly used by lecturers and students in lectures is Whatsapp Group, Zoom Meeting, campus E-Learning Website, and Google Classroom. The majority of difficulties experienced by lecturers and students in online implementation are the uneven quality of internet connections. Lecturers find it difficult to psychologically assess students who are attending lectures. Lecturers cannot ensure the seriousness of students in the lecture process. In addition, the lecturer also feels that it takes a lot of time in the matter of using the application or media technically, so it is quite disruptive to the course of lectures such as the slow pace of learning media and the length of time required for students to join in the meeting. Lecturers and students still consider online lectures to be ineffective

Abstract

This research aims to investigate the impact of the Discovery Learning model on students' scientific literacy skills in ecology at SMP Negeri 1 Delitua. The research method used was quantitative with a sample of 66 students from classes VII-5 and VII-6, selected using a purposive sampling technique. The instrument used is a scientific literacy test, with the independent variable (Discovery Learning model and direct learning model) and the dependent variable is students' scientific literacy abilities. The results of the research show that the application of the Discovery Learning model has a significant influence on the scientific literacy abilities of class VII-5 students who are at level 2 with a score of 31, which is in the poor category. However, after implementing the Discovery Learning model, scientific literacy ability increased to level 4 with a score of 69 and was included in the sufficient category.In conclusion, the application of the Discovery Learning model is effective in improving students' literacy skills on ecological material in class VII-5 SMP Negeri 1 Delitua. This finding provides an important implication for the development of a more problem-oriented student learning approach in improving students' science literacy.

Abstract

Based on the PISA 2022 results, the scientific literacy abilities of Indonesian students are still below the international average. This research aims to see the level of scientific literacy abilities of junior high school students in Medan City in 2023. This research was carried out at several representative schools designated by researchers as schools representing sub-districts in Medan City. Sample selection was carried out using stratified random sampling. From the 21 sub-districts in the city of Medan, one superior junior high school in each sub-district was selected. From the 21 selected schools, 1 superior 8th grader from that school was taken from each school. The instruments used are scientific literacy questions which have previously been developed by researchers following the indicators set out in the PISA 2018 framework which consists of 15 indicators for 3 scientific literacy competencies in the PISA 2018 framework. It can be concluded that the average scientific literacy ability of students in Medan City was still in the sufficient category. Student achievement was still low in several PISA 2018 framework scientific literacy competency indicators
