This study investigates the distance learning process of teachers during school closure due to COVID-19's impact. This research focuses on the introduction of distance learning, the obstacles faced by teachers and approaches to addressing different hurdles in the implementation of distance learning. This study collected data from mathematics and science teachers spread in junior and senior high schools in Aceh Province, Indonesia. Data were collected through a questionnaire from 353 teachers and interview from 6 teachers to get in-depth information related to the focus of this study. The results of the study revealed that teachers could not directly utilize various Information and Communication Technology (ICT) devices and online learning platforms that are widely available in supporting distance implementation, either due to the ability of teachers, parents' economic factors, limited internet access, and the absence of guidance. However, over time, the teacher can independently adapt to environmental conditions and the characteristics of students in carrying out distance learning.
This study aimed to know the components of the student creativity in problem solving that can be achieved through Model Eliciting Activities in preservice’s teacher of mathematics education of PTKIN in Aceh. This Research used qualitatif approach, since in this study want to describe the reality on the field namely data about the studets’ creativity in solving maths problem. The result showed that the componentsof flexibility obtained by contruction principle, the reality principle, and the self-just my assesment principle. Even so, there are student who got no flexibility with the third principle of the MEA, but only with the principles, the only reality MEA principle and the effective prototype principle. Mean while, the component of fluency is gained student by analysis of the construct documentation principle. The last component of creativity that is obtained through the construct shareability and reusability and the effective prototype principle. However there are students who do not obtain theses components due to the absence of new student-generated in carrying out problem-solving.
Dyscalculia is a kind of problems facing by many pupils beside of low-level reading skills. In fact, reading and basic arithmetic operation skills are very important in learning other subjects. The purpose of this study was to examine learning problems of dyscalculia students. The subjects of this study were five Madrasah Ibtidaiyah (MI) in Kabupaten Aceh Tamiang. The results showed that dyscalculia students face some difficulties in understanding the concepts or the process of calculation since they find some difficulties in visual processing. Moreover, dyscalculia students also face some difficulties in counting the numbers according to their sequences, memorizing and applying mathematical operations. As the consequence, dyscalculia students face some difficulties in solving even a simple mathematical problem.
One of the phenomenon in marine science that is often encountered is the phenomenon of water waves. Waves that occur below the surface of seawater are called internal waves. One of the mathematical models that can represent solitary internal waves is the modified Korteweg-de Vries (mKdV) equation. Many methods can be used to construct the solution of the mKdV wave equation, one of which is the extended F-expansion method. The purpose of this study is to determine the solution of the mKdV wave equation using the extended F-expansion method. The result of solving the mKdV wave equation is the exact solutions. The exact solutions of the mKdV wave equation are expressed in the Jacobi elliptic functions, trigonometric functions, and hyperbolic functions. From this research, it is expected to be able to add insight and knowledge about the implementation of the innovative methods for solving wave equations.
This paper presents the possibility of e-learning as connector among education institutions in the fourth industrial revolution. Since industry started emerging in this world, the industrial journey has reached level four that is currently well known as the fourth industrial revolution. Each stage of revolution has its own impact on education. The fourth industrial revolution requires educational sector synchronize the educational process in order for students or graduates to smoothly interact to the revolutionized changes. E-learning is one among educational entities that is relevant to the fourth industrial revolution in the area of education. With the connectedness as the main characteristic of the fourth industrial revolution, it gives a wide range of opportunities among education institutions particularly for higher education institutions to work, collaborate, and help each other within the platform of e-learning. Besides that, e-learning also enable the developed higher education to help primary and secondary schools at low cost and energy, particularly for professional development of teacher.
This study aimed to develop mathematics learning tools to help children with special needs of dyscalculia in elementary school. The procedural development of the device was through a 4-D model consisting of four phases; defining, designing, developing, and disseminating. However, based on the research objectives, this development was limited only to the development stage (develop), which is to the learning device testing activities. So the development of learning tools in this study consisted of three main stages, namely: defining, designing, and development. The results of this study illustrated that learning devices for children with dyscalculia learning disorders could help children more easily deal with learning difficulties. Specifically, it is on the topic of sequencing numbers, addition, and subtraction of integers.
This study aimed to develop learning tools to help children with learning disabilities of comorbid dyscalculia-dyslexia. The learning tools were developed using the 4D model. Each stage of development was conducted based on the materials focused on in this research, namely the topics of recognizing and understanding numbers, sorting numbers, and operating numbers. This study involved 280 students, ages between 7 and 8 years old, from four elementary schools. Students took a series of tests, and 11 students were found with comorbid dyscalculia-dyslexia. The results of this study provided an overview related to the learning tools developed, tested, and implemented in mathematics learning for students with dyscalculia and dyslexia. This finding was indicated by the analysis results of recognizing numbers, sorting numbers, and operating numbers using paired-sample t-tests (p< 0.05). The results showed increased students' essential mathematics ability based on the pretest and posttest scores.
The purpose of this study is to examine the solving skill of students on mathematical problem through online learning during COVID-19 pandemic, particularly in solving the problem related area and perimeter of trapezium. Data collection is conducted by performing problem solving skill test and interview. Furthermore, the data analyses is conducted by data reduction, data presentation and conclusion formulation. This study concludes that students have very good ability to solve the problem during the online learning through whatsapp group and g-meet. Detail of the steps used in examining the problem solving abilty as follow: 1) problem comprehension; students as research subject able to explain the problem by using their own terms, analyse the problem by stating the known and unsolved variables and illustrating the provided pictures 2) planning the problem solving; subject can determine other condition from the problem, selecting and structuring the steps to solve the problems 3) implementing the problem solving; subject solved the problem by using the selected formula accordingly 4) cross-checking; subject cross-checked the solutions by using other method and compared the results.
