Mobile-Assisted Language Learning (MALL) in Indonesia: Case on English Language Learning for Higher Students during COVID 19
No full textThe present paper, therefore, aims to develop deeper students’ understanding and perception regarding the use of mobile assisted language learning in the learning process. All schools and universities should eliminate offline learning and switch to online education. When this is enforced, not a few students find it difficult to access online learning. Some students may have privileges in the form of computers and internet access. This one can easily follow the learning delivered through online media used by the school/Learning management system.This study adopted qualitative research design where case study is used. In this study, the research participants are five students taken from university students who are currently taking English education. To hinder the ethical issues during the data collection and also the research process, the anonymity of the participants is implemented. The research participants also filled out the informed research consent form in order to share the agreement to be part of this study. There are some benefits gaining from implementing MALL such as learning flexibility and easiness. Students are not limited by the place and time to start studying and access some English sources. However, the comprehension supports for students from surrounding in mastering the technology use will enhance the learning process.Â
Factors Affecting Paddy Rice Production in Tanggetada District Kolaka Regency
Get PDFThe aim of this research is to find out what factors affect lowland rice production in Tanggetada district, Kolaka regency and to find out how the level of technical efficiency, allocative efficiency and economic efficiency of rice lowland in Tanggetada district, Kolaka regency. To examine the effect of the utilization of the factors of production used on the yield of lowland rice production, a multiple linear regression is used and to determine the level of economic efficiency from the use of the factors of production. production by switching between technical efficiency and price / allocative efficiency and any input factors. The results of the study indicated that the factor of production of land area, urea fertilizers and NPK fertilizers had a significant effect. Meanwhile, labor-intensive factors of production, nararel pesticides and seeds have no significant effect. and Based on the results of the allocative efficiency analysis, an average value of 3.18 was obtained. This means that it is not allocatively efficient, so it is necessary to add the use of factors of production and it is necessary to maximize the profits obtained by making efficiency in the cost elements of the factors of production in order to '' achieve optimal conditions. At the same time, the results of technical efficiency show that lowland rice cultivation is not technically efficient. so the use of factors of production should be added to increase the efficiency of lowland rice cultivation. And the value of economic efficiency shows that lowland rice cultivation is still not efficient. It is therefore necessary to make changes and increase the capacity to combine existing factors of production through training in order to achieve economic efficiency
The Need of Monitoring Forest Fires through Burned Area Mapping in Indonesia
No full textForest fires have become a regular phenomenon in Indonesia, especially in the dry season. They can be caused by natural and anthropogenic factor. Since Indonesia’s soil, especially Sumatra and Kalimantan, is a peatland type, this type of soil is highly inflammable, thus a small fire can easily spread and become massive. This phenomenon provenly disturbs the balance of the ecosystem and socio-economy of the affected country. Previous forest fires resulted in a higher risk of respiratory problems and increased mortality or the death of infants and children. The loss of biodiversity and the increasing amount of Green House Gas (GHG) Emissions that affected the change of climate is also the effect caused by those. For those reasons, the need of monitoring forest fires is essential, especially in climate change mitigation as fire disturbance is one of the key variables in it. This paper will further discuss the method of monitoring through burned area mapping using remote sensing techniques
E-Writing: The Effectiveness of Using Writing Application in Distance Learning
No full textThe primary aim of this study was to explore the effectiveness of teaching writing skill using E-Writing application in distance learning from the viewpoints of higher education students of Islamic State University of Semarang. Mix method were used as the research design. The quantitative data were obtained through one group pretest posttest design to know the effectiveness of the application to student’s writing achievement. Then, a questionnaire was used to investigate student’s attitude toward the writing application. The results of the writing test showed that student’s writing was improved. The average score of student’s pre-test score was increased for about 27 points, from 59 points to 86 points on post- test. The analysis of student’s questionnaire demonstrated conceptions about using technology of doing independent learning especially in English learning. The study showed that students admit the effectiveness of technology in distance learning and they believe that having learning independency will help them to adapt in any situation
PROFILING COLLOCATION USE IN ENGLISH TEXTBOOKS FOR VIETNAMESE STUDENTS
No full textThe study investigates (1) collocational profiles of an English textbook series for students from elementary to high schools in Vietnam, (2) the relevance of collocations targeted to high frequency collocation lists suggested in the literature, and (3) the recycling of the targeted collocations. An English corpus of 312,770 word tokens was built from the textbook series from which 13,292 collocations of verb-noun and 11,079 collocations of adjective-noun patterns were identified. The study found that frequencies of occurrences of collocation tokens and types increase from one grade level to another. Collocations targeted in the textbooks only cover 10.5% of the collocations recommended in an academic collocation list, and 31% were identified not high-frequency collocations. 76% of collocations are not recycled or recycled not to the point where learning is likely to occur. Implications for learning and teaching collocations and materials designing are discussed

Science Learning Performance and Retention of Biology Concepts Among Secondary Students
Get PDFThis study investigated into effects of science learning materials on performance and retention of biology concepts among senior secondary school two students in Afijio local government area of Oyo State. The study was Quasi-experimental involving pretest, posttest equivalent group design. In this design, 40 students were randomly selected from SS2, pretested to ascertain their group equivalence, and then divided into two groups (experimental and control) using the lottery method of sampling techniques. The experimental group was taught biology concepts with science learning materials,while the control group was taught the same concepts without science learning materialsfor three weeks. The two groups were pretested and post-tested for performance and retention, respectively. The data collected were analyzed using a simple percentage method, mean, and standard deviation. Based on the data generated and results obtained from the experiment, the findings revealed that the use of science learning materialsin the leaching of Biology concepts significantly improves the academic performances, enhances the retention ability of students involved in the study. The study also revealed that students exposed to the use of science learning materialsin the teaching of biology concepts generally had better academic performances and retention ability than students who were not exposed to the use of science learning materialsin the experiment. The study recommended, among others, that the Ministry of Education should provide science learning materials for effective teaching and learning of Biology concepts in Oyo State Senior Secondary Schools. Keywoard: Science Learning Performance, Retention, Biology Concept
