Abstract

[English]: This study aimed to assess attitudes of prospective primary mathematics teachers (PPTs) toward statistics and how these attitudes are influenced by gender. It adopted Attitudes Towards Statistics Survey (SATS-36) and involved 455 PPTs from 9 Teachers Training Institutions (TTI).  Exploratory factor analysis (EFA) was performed because the model fit for confirmatory factor analysis (CFA) failed to yield good indices of reliability and validity. The validated model only contains 27 items in four factors that assess attitudes including competence, values, difficulties, and interests. The prospective teachers’ attitudes toward statistics and the impact of gender were then evaluated using a modified four-factor model. The finding shows that PPTs have a positive attitude toward statistics. In specific, the female participants tend to have a more positive attitude toward statistics than the male. [Bahasa]: Penelitian ini bertujuan menilai sikap calon guru matematika sekolah dasar terhadap statistika dan bagaimana sikap tersebut dipengaruhi oleh jenis kelamin. Penelitian ini mengadopsi Survei Sikap terhadap Statistik (SATS-36) dan melibatkan 455 calon guru dari 9 Lembaga Pendidik Tenaga Kependidikan. Analisis faktor eksploratori (EFA) dilakukan karena model yang cocok untuk analisis faktor konfirmatori (CFA) gagal menghasilkan indeks yang baik untuk reliabilitas dan validitas. Model yang telah divalidasi hanya memuat 27 item dalam empat faktor untuk menilai sikap yang meliputi kompetensi, nilai, kesulitan, dan minat. Sikap calon guru terhadap statistik dan dampak gender kemudian dievaluasi menggunakan model empat faktor yang dimodifikasi. Hasil penelitian menunjukkan bahwa calon guru mempunyai sikap positif terhadap statistik. Secara spesifik, calon guru perempuan lebih mempunyai sikap positif terhadap statistik daripada calon guru laki-laki.

Abstract

Low math learning outcomes in students, especially in comparison materials, are reflected in low scores on the National Exam and learning outcomes in the classroom. Several factors, both internal and external, can cause learning difficulties experienced by students. This study aims to analyze the obstacles to students' difficulties in learning mathematics and their causes. The subjects involved were 30 students. This type of mixed research uses data collection methods through tests, interviews, and questionnaires. The instruments used are closed questionnaire sheets and interview guidelines. Data analysis techniques using data collection are interactive model data analysis techniques, especially in the data reduction and conclusion drawing sections. The results revealed that 12 students experienced difficulties in interpreting language. These difficulties include difficulty understanding the problem's core and integrating everyday language into the depth of mathematical language. The conclusion that can be formulated is that the difficulties experienced by students arise because of themselves and from people around their school environment. This research implies that educators design materials by improving concepts and mathematical literacy to overcome student difficulties.

Abstract

The low level of direct interaction between teachers and students due to the restrictions and distance that must be observed forces students to learn independently. However, not all students have online skills. Therefore, teachers must develop competence by presenting the right model and by government policy, both online and offline. This learning model is blended learning. Teachers have no other choice but to carry out good blended learning management so that learning activities can continue. This research aims to analyze the effectiveness of blended learning management and online skills on students' learning independence. The method in this research is quantitative with an export facto type of research, namely comparative causal research. The data collection technique is by distributing instruments in the form of questionnaires to each teacher respondent by first creating a Google from link. The population in the study were all teachers in one district with a research sample of 90 people from 4 schools spread across one district. Data analysis techniques are correlation and regression. The research results show that blended learning management and online skills have an impact on student learning independence. The impact of the blended learning model and students' online skills is 52.10%. The conclusion is that to increase student learning independence, teachers must carry out the learning process using the blended learning model optimally. The research implies that teachers have implemented the blended learning model by training students who have difficulty online.

Abstract

In the 21st century, teacher education is required to look for new ways to improve the quality of mathematics teachers. However, the facts seen from the PISA test show that the achievement of Indonesian students is always low. Additionally, the OECD reports that only 1% of students in Indonesia are able to answer questions at a low level. The research aims to identify and find out what teacher educators face in preparing mathematics teachers with 4C skills and knowing solutions to 4C difficulties. The research method is a qualitative exploratory case study with a single case study design. The subjects were teachers at schools and prospective teachers at universities. Data collection techniques using documents and interviews. Ten prospective teachers from a university perspective and ten in-service teachers from a school perspective. The data analysis technique uses the constant comparative analysis method. The research results found five common challenges: lack of learning ability and motivation among prospective teachers, pedagogical challenges, lack of capacity and conceptual understanding of 4C skills among teacher educators, lack of supporting programs and facilities, and political challenges. Another finding is that teacher capacity is the two main concerns; universities must implement new, dynamic learning systems to equip mathematics teacher graduates with resources that teach 4C skills innovatively.

Abstract

This study aims to determine the effect of the Numbered Head Together (NHT) and Expository Learning Model (ELM) learning models on student learning outcomes in derived mathematics. The method used in this research is a quasi-experimental method, namely the Nonequaivalent Control Group Design. The experimental class was given a Numbered Head Together (NHT) The NHT model for class XI SMA IPA 5 and XI SMA IPA 1 as conventional classes is given in the form of the ELM model. Data analysis used the t test, where the results showed: 1) there was a significant increase in student learning outcomes in derived material using the Learning Numbered Head Together (NHT) model, 2) student learning outcomes in mathematics were higher using the Learning Numbered Head Together model. (NHT) than the learning outcomes obtained with the Expository Learning Model (ELM) model. This can be seen from the test results with the t. Test, mark Tcount = 89,12 And value ofT’ table = 1,67 so that TCount>T’table = 89,2>1,67, so rejected and accepted. In conclusion, students who are taught mathematics using the NHT model understand much more and have very good results compared to the ELM model. Suggestions, in implementing mathematics material, it is expected that educators use the NTH learning model to improve learning outcomes and produce good thinking concepts in mathematics.

Abstract

The Indonesian government encourages all teachers to be certified in the hope of improving teachers’ performance. The purpose of this study was to explore the effect of teacher certification on teacher performance in the northern Toraja region. Utilizing quantitative methods approach, this study randomly sampled 94 students and teachers. The students were subject to a distribution instrument to evaluate the performance of certified and uncertified teachers. To support the quantitative data a short interview was conducted to 10 randomly selected teachers regarding their perception of the relation between certification and teacher performance. The collected data were subjected to validation test, reliability test and simple linear regression test. The results show that there are 33.75% students strongly disagree with the performance of certified teachers who have been certified but there are 65.85% who agree and strongly agree with the performance of teachers who have been certified. While teachers who have not been certified 35.16% strongly disagree and disagree with the performance of teachers who have not been certified and only 53.88% agree and strongly agree. Conclusively, there is an effect of teacher certification on teaching performance although not very significant between certified and uncertified teachers. Some recommendations for the government regarding the current practice of teacher certification are included.
