Many studies have revealed that fraction is a complicated mathematics topic for students. Students struggle to solve problems including comparison and addition of fractions correctly. However, some students often make some common mistakes in solving the mathematics problems. There are three types of errors in solving mathematics problems, which are factual error, procedural error, and computational error. This study was aimed at investigating various mistakes by students in problems related to fractions. A set of validated problems about comparing and adding fractions was assigned to third grade students of SD N Laboratorium Unesa Surabaya. The results indicated that some students were not aware on how to compare and add fractions. Most of these students employed incorrect strategies categorized as procedural and conceptual errors.

Many studies showed that teachers and prospective teachers have difficulty solving percentage problems. This research is a qualitative descriptive study that aims to investigate the prospective teachers’ strategies in solving problems on the topic of percentages. A total of 250 students majoring in Mathematics Education and Primary Education at IAIN Syekh Nurjati and IAIN Pekalongan were purposively selected to participate in this study. The results showed that only less than half of the participants (40.1%) could give the correct answer. Qualitative data on the strategies used by prospective teachers on the percent question show that (1) teacher candidates ignore the importance of the % symbol and consider the % symbol only as a unit of measurement, (2) teacher candidates ignore the essential role of the reference quantity in the percent question, (3 ) teacher candidates are not used to solving percent problems related to determining initial values before discounts and assume that any percent problem can be solved using multiplication or division.
This study aims to promote students' critical thinking skills of trigonometry by using STEM-based learning. This study was an experimental study conducted on 10th grade students of social studies MAN 1 Cirebon. The data were collected by using tests. The result showed that there was an improvement of students’ critical thinking skills after the implementation of STEM-based learning on trigonometry. Students’ posttest score of 79.83 was greater than the pretest score, which was 30.81. The paired sample t-test analysis showed that there was a significant increase from pretest to posttest score. Thus, it can be concluded that there STEM-based learning can be applied to promote students' critical thinking skills.
Sektor pertanian merupakan bagian penting dari aktivitas ekonomi dalam masyarakat. Sektor pertanian yang unggul berhubungan dengan terjaminnya ketahanan pangan. Ketahanan pangan merupakan faktor penting yang harus diperhatikan agar proses industrialisasi dan pembangunan ekonomi berjalan dengan baik. Jika sektor pertanian diolah dengan baik maka akan meningkatkan kesejahteraan masyarakat. Kesejahteraan memerlukan pengelolaan ekonomi yang sebaik-baiknya. Metode yang digunakan dalam penelitian ini adalah pendekatan kuantitatif. Penelitian ini bertujuan mengidentifikasi faktor-faktor yang dapat meningkatkan produktivitas diantaranya faktor tanah, modal, tenaga kerja dan manajemen produksi. Penelitian ini juga bertujuan untuk mengetahui apakah faktor-faktor tersebut mempunyai pengaruh terhadap kesejahteraan petani. Dari hasil analisis data diperoleh bahwa 86,5% faktor-faktor produktivitas pertanian memiliki pengaruh positif terhadap kesejahteraan petani. Faktor-faktor tersebut adalah faktor tanah, modal dan manajemen produksi. Adapun tenaga kerja tidak memiliki pengaruh yang signifikan terhadap tingkat kesejahteraan masyarakat.
Merely providing the formula of area in the learning activity can impede students’ deep understanding of the concept of area. This study was a qualitative design research that aimed to develop a learning design by using the context of pixel art and grid paper to build students' knowledge of the concept of area measurement. There were three stages in this study, namely, preparation, teaching experiment, and retrospective analysis. The subjects of this study were 25 students of P3 (Primary 3) SD Global Inbyra School. However, the discussion focused on a group consisting of three students. The research subjects were given a mini lesson consisting of 2 meetings. It can be seen from the first meeting that the pixel art drawn by the students built on their initial measuring ability because they automatically notice that half square and half square make up 1 square. At the second meeting, students demonstrated their ability to estimate the number of squares (area) in an irregular picture. In the activity of making any shapes that have an area of 20 square units, students were aware that to find the area of the rectangle, they can use repeated addition which can be directed to the area of the rectangle (p x l).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
