Abstract

The development of teacher professional abilities through training is an effort to improve teacher performance by increasing their professional competence. The main objective of developing teacher professional abilities through training is to solve teacher performance weaknesses both at present and in the future towards a more desirable level of performance. Because the development of teacher professional abilities through training is so important and requires a lot of money, it is necessary to research to find a real effect on teacher competence and performance. The research problems formulated are: 1) dimensions of teacher professional ability development through training; 2) teacher professional competence; and 3) teacher performance. The research approach is quantitative with a sample of 335 from a population of 2,064 junior high school teachers in Bandung. Data were obtained from teachers using a questionnaire. The data is processed and interpreted using path analysis as an inferential statistical technique by first testing statistical assumptions, including transforming ordinal data into intervals and data normality testing. The study concluded that the development of teacher professional abilities can improve teacher competence and performance, which is expected to ultimately improve the quality of student learning. The implications include: 1) it is necessary to develop effective training; and 2) competence with performance is important to promote better teaching and learning. Based on these implications, there are several recommendations, namely: 1) increasing the development of teacher professional abilities through technical assistance and quality control group forums; (2) designing the development of teacher professional abilities that have a direct impact on the teaching and learning process; (3) develop a model with competency as the dependent variable; and (4) recommend the human side of the organization as a determinant factor that needs to be investigated.

Abstract

Mathematics is an essential subject to study so that it must be pursued in its implementation and possible. The existence of the covid-19 pandemic requires all learning activities to be carried out online. But in practice, online learning experiences several obstacles, especially in learning mathematics. For this reason, the purpose of this study is to describe the constraints in the online-based mathematics learning process (e-learning). This study uses a descriptive method with a qualitative approach. The subjects in this study were students of class VIII SMPN 1 Rawamerta. The research instrument was in the form of a student response questionnaire regarding online-based learning (e-learning), which consisted of seven closed questions and four open questions. Data collection was carried out by distributing the google link form to the student response questionnaire to the research subject. Data analysis was carried out descriptively by testing the validity of the data through triangulation techniques. The results showed that students' obstacles in online-based mathematics learning (e-learning) were technical and personal constraints. Technical constraints are in the form of an unstable internet network, internet quota, and teacher explanations that are not heard clearly. In contrast, unique constraints are the lack of students in understanding the learning material and feeling lazy to take online-based mathematics learning.

Abstract

Pembelajaran matematika selain mengembangkan pada aspek kognitif siswa juga mengembangkan pada aspek afektif siswa. Aspek afektif salah satunya adalah self efficacy atau efikasi diri yang artinya keyakinan diri terhadap kemampuan yang dimiliki. Self efficacy matematika mempengaruhi keberhasilan dalam pembelajaran matematika. Penelitian ini dilakukan yang bertujuan untuk mengetahui self efficacy matematika dalam pembelajaran di SMPN 2 Karawang Barat. Subjek penelitian ini adalah kelas VIII A berjumlah 37 siswa. Data diperoleh dengan menggunakan instrumen angket yang terdiri dari 18 pernyataan. Berdasarkan hasil analisis menunjukkan bahwa rata-rata skor keseluruhan adalah 11,40 berada dalam kategori sedang. Indikator self efficacy ada 5, yaitu indikator pertama memperoleh rata-rata 11,51 berada pada kategori sedang, indikator kedua 12,14 kategori sedang, indikator ketiga 11,62 kategori sedang, indikator keempat 13,24 kategori sedang, indikator kelima 8,50 kategori tinggi.

Abstract

This study aims to describe students' metacognitive abilities in solving math problems in terms of gender. The type of research used in this research is qualitative with a descriptive exploratory approach. The subjects of this study were two students of grade 7 SMP Negeri 2 Sukatani. The instruments used were tests and interviews. With the data analysis technique using 4 flow, namely: 1) data collection, 2) data reduction, 3) presentation of data, and 4) drawing conclusions. The indikators used are three elements, namely planning, monitoring, and assessment (evaluation). The results of this study indicate that male students are not good enough to apply metacognition skills in solving math problems, because male students have not met the three indikators, only reaching 1 indikator, namely at the planning stage. Meanwhile, female students have implemented metacognition skills well, because they have fulfilled three indikators, namely planning, monitoring, and evaluation

Abstract

Statistical literacy skills are an important aspect that students need to have in building life skills during the pandemic. An alternative that can be done in building statistical literacy skills is through learning mathematics, especially in statistical material. This article aims to describe the statistical literacy skills of students during online learning during the pandemic, as well as to describe the difficulties experienced by students in solving problems related to statistical concepts. This research was conducted using a qualitative approach with a descriptive method. The subjects in this study were 25 students of class X at SMAN 1 Setu Bekasi. The data collection technique was carried out using a statistical literacy ability test instrument with the scope of the test material, namely Statistical material. This study resulted in the acquisition of the percentage of students' statistical literacy skills which were still low in each indicator. The ability of students to interpret the data indicators has the largest percentage, which is 68%. And on the indicator presenting the data, it gets the lowest percentage, which is 46%. Some students still cannot understand statistical concepts well so they are not able to present data and provide statistical conclusions correctly.

Abstract

The purpose of this study was to find out how big the level of student error when solving mathematical problems on exponential material based on the type of Newman error in class X MIPA 1 SMA At-Taubah Tirtamulya which consisted of several types of errors including (1) errors due to lack of accuracy or carelessness, (2) errors in process skills, (3) errors in understanding questions, (4) errors in notation, and (5) errors in concept. There were 20 students during the research and then 5 subjects were selected for analysis and interviews. This type of research is descriptive qualitative. This study uses data collection techniques in the form of description tests and interviews. This study uses data analysis techniques, namely reducing data, presenting data, and drawing conclusions. The result of the study found that students errors when working on exponential material problems with the types of errors due to lack of accuracy or carelessness, errors in process skills, errors in understanding questions, and errors in using notation were classified as very low, while the types of errors in concept were classified as moderate. The type of student error that the researchers found the least in this study was notational error, while errors in concepts were the most common errors found in this study.
