The coronavirus covid19 pandemic crisis in Indonesia has caused all lectures to be conducted online (online learning), so that all students have experienced face to face learning, blended learning, and online learning. The purpose of this study is to determine student perceptions of learning, which learning is most preferred by students between face to face learning, blended learning, and online learning. The research method used is descriptive research with a quantitative approach. Respondents were 100 students of Islamic Religious Education study programs. The results showed that face to face learning was the most preferred choice by students of the Islamic Religious Education study Program in IAIN Takengon, which is 78 students or at 78%, while a total of 20 students or 20% of the study was done in blended learning, and only 2 students or 2% who chose online learning.

This research was conducted to look at the increase in mathematical communication towards cooperative learning type Course Review Horay assisted PowerPoint in the seventh grade of  SMP Negeri 1 Takengon. This research used Experiment Research with Quantitative research. SMP Negeri 1 Takengon was the population of research. Two classes were determined by purposive random sampling for the sample of research, called experimental class and control class. The experimental class was taught by using a cooperative learning type Course Review Horay assisted PowerPoint while the control class was taught by STAD. The conclusion was that by using a learning model Course Review Horay, the students more active because it can be suggested with the peers and its language. Things can improve the ability of mathematical communication students. Along with the development of their understanding of the material has been taught students to do math activities that encourage the application of mathematical communication ability.

This study aims to know (1) the effect of Geogebra assisted blended learning in enhancing spatial geometry ability, (2) the response of the learning. This research method uses quantitative research with a quasi type experimental design and research design using the pretest-posttest control group. The subject was Mathematics Education students on State Institute of Islamic Religion (IAIN) Takengon who studied field and space analytic geometry in the academic year 2019/2020. Data collection using tests and questionnaires that are validated by experts. The data hypothesis test uses the t-test involving requisite pretests (normality and homogeneity) beforehand. The results showed that Geogebra assisted blended learning was effective in enhancing geometry spatial ability, and students’ response was also very good.

Along with the development of information technology, which more rapidly, the need of a concept and mechanism of Information Technology-based learning becomes inevitable. Then, concept known as e-learning take affect transformation of occurs conventional education into digital form, both the content and the system that is bridged by the technology of internet. The concept of e-learning gives the possibility of interaction between lecturers and students, either the students in the classroom or outside the classroom intensively. This study aimed to obtain e-learning media based Moodle is effective to support the development of science and Islamic studies in Gayo through a series of development process. The finding of the study showed that e-learning based Moodle was conducted by using 4-D model (Four D Model). The results also showed that of development activities are: (1) e-learning media in Gayo which can be seen in www.elearning-gayobelajar.com and (2) the use of guide books for lecturers and teachers. The Finding also indicated that the development of E-learning based Moodle is reliable or has a high level of reliability if t is used in university.
