The objective of this study was to know the teachers' pedagogic competence to manage the teaching and learning of IPA at SD Negeri Tamansari 1 Kota Yogyakarta and MIN Kota Yogyakarta II. The research methods of the study is descriptive qualitative. Data were collected through observation, interview, and documentation. Data were validated by using triangulation. Data were analyzed descriptively. The result of data findings shows that the teachers' pedagogic competence to manage the teaching and learning of IPA at SD Negeri Tamansari 1 Kota Yogyakarta is categorized "good". Meanwhile, the teachers' pedagogic competence to manage the teaching and learning of IPA at MIN Kota Yogyakarta II is categorized "poor". The similarity of the teaching implementation for both schools is they try hard to develop a democratic teaching and students' center-based teaching. They have a different teaching method. At SDN Tamansari 1 Kota Yogyakarta, the teachers implement minds-on and hands-on teaching process, that is, the experimental, demonstrational, and observational teaching, while the teachers at MIN Kota Yogyakarta implement theoretical (rote learning) teaching approach. Those differences were caused by some factors, such as: teachers' qualification, teachers' certification and professionalism, and the students' background.
The purpose of research is first, to know readiness of student and teacher to e-learning. Second, to identify the needs of students to teaching materials based Edmodo e-learning. Third, developing e-learning materials based Edmodo. Fourth, examine the effectiveness of e-learning teaching materials based Edmodo. Research using Borg and Gall model and experiment using pretest posttest control group design. The sample is selected using cluster technique. Data were collected using questionnaires and tests. The result of the research is first, readiness of elearning students and teachers in ready state. Second, students need instructional materials based Edmodo e-learning combined with conventional learning and are equipped with electronic teaching ma-trials. Third, developed edmodo edited e-learning materials that have been validated by experts and tested. Edmodo based e-learning teaching materials on effective geography learning improve student learning out-comes.
Online learning has been widely applied at various levels of education, including lectures for prospective teachers of elementary school students in Indonesia. However, student activity in learning is still an obstacle in this study. This study describes student activity in online discussions. The discussion was conducted three times with different topics. The activity can be examined from the students' posts during the three discussions. The three aspects of the activeness were the number of posts in each discussion, participation in the three discussion topics, and the number of words in each post. These results were analyzed descriptively to see the trend of active discussion. The findings of this study show the role of lecturers in providing appreciation and feedback. The role of friends in reinforcing other friends' opinions determines the increase in activity in discussions. Social presence, self-esteem engagement, and social learning are essential issues in increasing this activity.
The ability to use technology in learning or Technological Content Knowledge (TCK), is one of the skills that must be mastered by teachers in the era of society 5.0. Therefore pre-service teacher must also have the ability to use technology in learning. This study aims to determine TCK pre-service teachers in developing interactive multimedia in mathematics learning. This research is a comparative study. The study population was 300 students of Ahmad Dahlan University Primary School Teacher Education. The research sample was taken randomly as many as 169 students. The research instrument uses the TCK assessment sheet that has been validated by experts. The results showed that the significance level of 5% TCK for students who developed captivate-assisted learning multimedia was better than students who developed flash-assisted learning multimedia.
Abstract. Indriani F, Siregar U, Matra DD, Siregar IZ. 2019. Ecological aspects and genetic diversity of Shorea balangeran in two forest types of Muara Kendawang Nature Reserve, West Kalimantan, Indonesia. Biodiversitas 20: 482-488. Shorea balangeran (balangeran) belongs to the Dipterocarpaceae family that is distributed naturally in Indonesia with a wide range of ecological conditions including peat swamp and heath forests. Good adaptability of S. balangeran remains unknown concerning molecular (genetic) responses that are important to provide scientific knowledge for supporting forest restoration, especially for peatland restoration efforts. The main objective of this research was to analyze the ecological aspects and genetic diversity of S. balangeran in two types of forests, namely: peat forests (wetland) and heath forests (dry land). Field research was conducted in Muara Kendawangan Nature Reserve, West Kalimantan following standard vegetation analysis by establishing purposively sample plots (50 m x 50 m). Genetic diversity was assessed by RAPD analysis using ten random polymorphic primers. Results showed that both in heath and peat forests, S. balangeran was dominant, but only at pole and tree stages indicating that poor regeneration capacity of S. balangeran. This finding also confirmed the critically endangered status of S. balangeran as listed in the IUCN Red List of Threatened Species. Genetic analysis using RAPD did not show a clustering of S. balangeran between peat forest and heath forest populations, indicating that S. balangeran has good adaptability to grow in both forest types.
