Abstract

The sudden change caused by the global pandemics of COVID-19 leads to the classroom transformation from classical face-to-face meetings into virtual. The development of technology enables classroom variation by providing various applications that can be employed to facilitate learning activities. Nonetheless, not all situations suitable to use advanced technology during distance learning. Some students are living in remote areas with limited internet connection. This study aims to offer an alternative if most of the students were having difficulties with the internet and minimum devices to download heavy applications. The alternative is by using a chat group with an emphasis on the students’ interaction during the lesson. This descriptive study was conducted at a university in Mataram, Indonesia. The subject was 17 students in the Mathematics Education Study Program who follow the course of Abstract Algebra. The data were gathered from students’ observation during the lessons and students’ written work in the middle semester test. The data were analyzed by using descriptive qualitative method. From the analysis, it was found that the students’ activity during distance learning was 83.5%. Furthermore, 88.23% of students achieved the minimum score for the middle semester test (more than 56).

Abstract

Based on the results of a preliminary study conducted on 20 children, the number of children who got 4 stars was 3 children with a percentage (15%), 3 stars were 4 children with a percentage (20%), 2 stars were 3 children with a percentage (15%), while those who got 1 star were 10 children with a percentage (50%). This shows that there are still many children who have not been able to count from 1-10, which means that many children have not achieved their learning completeness. For this reason, it is necessary to take action so that children's learning completeness can be achieved. The purpose of this study was to see the effectiveness of using smart tree media in improving children's numeracy skills 1-10. The design chosen for this study was the Kemmis and Taggart Classroom Action Research Model with 3 cycles. The data collection techniques used are performance techniques to collect data about students' numeracy skills and observation techniques to collect data about the learning process when each action cycle is carried out. The results of the data analysis showed that after the third cycle was completed, the learning completeness of the children reached 80%, meaning that there were 16 children who achieved learning completeness. The conclusion is that smart tree media can improve numeracy skills 1-10 in group A children at An-Nur Labuapi Kindergarten.Berdasarkan hasil studi pendahuluan yang dilakukan pada 20 anak, 3 anak (15%) mendapat 4 bintang, 4 anak (20%) mendapat 3 bintang, 3 anak (15%) mendapat 2 bintang, dan sisanya 10 anak (50%) mendapatkan 1 bintang. Hal ini menunjukkan masih banyak anak yang belum dapat berhitung dari 1-10, yang berarti banhyak anak yang belum tercapai ketuntasan belajarnya. Untuk itu perlu adanya Tindakan yang dilakukan agar ketuntasan belajar anak dapat tercapai.

Abstract

This research is an exploratory descriptive with a descriptive quantitative approach or mix-method which aims to analyze the thinking processes of pre-service mathematics students based on the SOLO taxonomy in solving differential equation problems. The subjects were 86 pre-service mathematics students of the fifth semester of the mathematics education study program who were selected using the purposive sampling technique. Meanwhile, data were collected using problem-solving tests and interviews and then analyzed using descriptive and qualitative statistics with the following stages: (1) transcribing test and interview data, (2) coding segmentation, (3) analyzing student thinking processes in solving differential equation problems, and (4) drawing conclusions. The results showed that pre-service mathematics students' thinking levels were at the pre-structural level (6.98%), uni-structural (25.58%), multi-structural (60.47%), and extended abstract (6.98). Meanwhile, there is no one at the relational level in solving the problem. These results indicate that students need to be well supported and facilitated in problem-solving to achieve higher levels of thinking, such as the relational and extended abstract levels.

Abstract

As an effort to develop the teaching profession, Lesson Study for Learning Community (LSLC) emphasizes the importance of collaborative and continuous learning assessment based on the principles of collegiality and mutual learning to build a learning community. Based on discussions with the head of Darussholihin Islamic Boarding School (Ponpes) NW Kalijaga, East Lombok, principals of MTs-SMP, MA-SMA, and Vocational Schools fostered by Ponpes Darussholihin NW Kalijaga, it was revealed that: mathematics is one of the subjects that most students are less interested in. MTs-SMP, MA-SMA, SMK fostered by Ponpes Darussholihin NW Kalijaga, as well as most mathematics teachers still have difficulty planning and implementing learning strategies that can guide students in finding mathematical concepts, principles, and problem solving. To solve these problems, assistance is needed, through LSLC activities for school mathematics teachers at Ponpes Darussholihin NW Kalijaga, in order to resolve problems related to the implementation of mathematics learning. This service activity is carried out by utilizing several methods, namely: lectures, questions and answers, discussions, and providing assistance when mathematics teachers carry out the LSLC steps, including Plan, Do, See, and Re-design activities. Through mentoring activities carried out from September 18 to October 2, 2021, it was concluded that mentoring activities could: i) improve the understanding and skills of Mathematics teachers in schools at Ponpes Darussholihin NW Kalijaga in designing (plan), implementing (do), reflecting (see), and re-design of learning as regulated in the 2013 curriculum; ii) increasing collegiality among mathematics teachers at the Darussholihin Islamic Boarding School's fostered schools, NW Kalijaga.
