The scientific knowledge acquired by elementary school students is subpar. Difficulty comprehending the material and the adoption of inefficient learning paradigms both contribute to students' poor performance in class. Moreover, efficient learning models might be of great assistance in the journey toward one's educational goals. The Numbered Head Together (NHT) method is one example of such a framework. The study's overarching goal is to ascertain whether or not using the Numbered Heads Together learning paradigm improves student performance. In this work, quantitative methods were used with a quasi-experimental strategy. Non-probability sampling was used as the methodology. A total of 51 students participated in the research (26 in the experimental group and 25 in the control group). The testing instrument is being used in this investigation. The average for the experimental group was 75.38, whereas the norm for the control group was 63.00. In general, the experimental group outperformed the control group. Findings showed that the experimental class that employed the Numbered Head Together paradigm did better on tests than the control group. This illustrates that incorporating Numbered Head Together into the classroom may boost students' knowledge retention and application.

The purpose of this study was to analyze the mathematical problem-solving abilities (KPMM) of high school students based on math anxiety and gender. The methodology use in this study is qualitative, specifically using a case study approach. The study utilized students from SMA Negeri 31 Tangerang Regency, who were in the 11th grade and studying arithmetic sequences and series. The research subjects were six people, two from each category of math anxiety, chosen through purposive sampling using Winstep and based on an analysis of the person map table. The instruments used were a six-item math problem-solving ability test and a 27-item math anxiety questionnaire that had been validated by expert lecturers and mathematics teachers and was therefore feasible to use. Reduction, categorization, synthesis, and a conclusion were all used to analyze the data in this study. Based to the study's results, gender did not have a significant impact on students' mathematical problem-solving abilities. However, what distinguished them was the category of math anxiety. Male and female students with high levels of anxiety in maths were only able to fulfil one KPMM indicators, but those with moderate and low levels of anxiety were able to fulfil three.

Penulisan artikel ini bertujuan adalah untuk mengetahui perbedaan hasil penentuan indeks bias menggunakan dua metode yang berbeda. Nilai indeks bias kaca dapat ditentukan dengan menggunakan berbagai metode, salah satunya adalah prinsip interferensi dan prinsip pembiasan Huygens. Pada penentuan indeks bias kaca dengan prinsip interferensi, metode yang digunakan adalah dengan menggunakan cahaya koheren yang terhambur di cermin datar berdebu untuk mendapatkan pola-pola interferensi, kemudian menggunakan laser pointer hijau dan merah dengan membuat variasi jarak layar dengan kaca cermin. Adapun hasil eksperimen yang telah dilakukan beberapa pengamat diperoleh nilai indeks bias kaca sebesar 1,62 ± 0,04 menggunakan laser pinter merah dan 1,74 ± 0,07 menggunakan laser pinter hijau. Sedangkan pada penentuan indeks bias kaca dengan prinsip pembiasan, digunakan dua jenis kaca yaitu kaca Korona dan kaca Flinta. Pengukuran dilakukan sesuai dengan prinsip pembiasan cahaya pada kaca plan paralel, yaitu melakukan teknik pengambilan data secara berulang dengan memvariasikan besar sudut datang dan sudut pantul sehingga akan diperoleh nilai indeks bias rata-rata kaca korona dan indeks bias rata-rata kaca flinta. Pada indeks bias kaca korona diperoleh nilai sebesar 1,478 dan pada indeks bias kaca flinta diperoleh nilai sebesar 1,6203.
