Pengembangan E-Modul dalam Pembelajaran Matematika SMA Berbasis Android

This study is a mixture of quantitative and qualitative with sequential explanatory designs. The study aims to (1) analyze the improvement of student achievement in learning after scaffolding, (2) evaluate the level of students 'mathematics anxiety, and (3) describe the role of scaffolding in changing students' perceptions of mathematics anxiety in classroom learning. Sampling through random sampling techniques obtained by students of class X-IPA-1 and X-IPA-2 in SMA Negeri 6 Semarang. Quantitative data analysis uses statistical test techniques: normality test, paired sample t-test, and N-gain test. Qualitative data analysis through interactive methods namely data collection, data reduction, data presentation, and drawing conclusions. Data validation techniques through the source and method triangulation. The results showed that (1) there was an increase in student learning achievement after the application of the scaffolding strategy by 33.0% to 34.5%; (2) there was a decrease in the level of mathematics anxiety in students by 90.4%; (3) through scaffolding, students succeed in reflecting and correcting mistakes in solving previous problems. This means scaffolding can be an effective strategy to help students move across different Zones of Proximal Development (ZPD). The scaffolding strategy has also created a positive classroom environment that encourages students to learn mathematics without fear.

“…Significance of the existence of mathematics is rarely beneficial to the students that math becomes abstract and tend to be filled with numbers that are not meaningful [9]. Though math is a subject that can be used as a tool for other sciences [10].…”

Zulkardi³

et al. 2020

Ethnomathematic is one of mathematics learning innovations which integrate cultures to preserve local cultural values. A treasure quest at Musi River Palembang is included as a culture because it is the community activity with its unique characteristic carried out at Musi River to meet the necessities of life, and is passed down from one generation to the next generation. The research aims to explain aspects of mathematical computation to treasure quest at Musi River Palembang. A literature study is a method used in this research. Firstly, formulating research problem was how the mathematical aspects connect to the finding of treasure quest at Musi River Palembang. Then, literature related to the problem of the study was reviewed. The next step was evaluating data based on the literature to answer the research problem. After that, data analysis was conducted. Descriptive analysis was used to analyze the data. Lastly, the data was interpreted to obtain a conclusion. The interpretation showed that the treasure quest at Musi River had mathematical counting aspects namely, counting the number of human resources in a treasure quest group; counting the wages for each person in the team based on his or her duties; counting expenses required for a treasure quest; counting the number of objects obtained, and determining the sale price of the objects. The activity also contained a mathematical concept in the mathematics learning of some subjects at VII grade of junior high school level namely, the operation of the material count, social arithmetic, and sets

“…Nonetheless, most students encounter difficulties in trying to understand mathematics subject through reading or doing activities by themselves. There are a lot of efforts and skills required for teachers to design and apply proper learning methods embedded the scientific approach to make students understand materials in mathematics classrooms [16]- [18]. Besides, the time allocation in designing lesson plan as well as the complicated processes for evaluation [15][16] were among the concerns raised by mathematics teachers.…”

“We Need Supervisors”: Problematic Implementationof Curriculum 2013 among Mathematics Teachers

Setiawan¹,

2020

The development of the curriculum is a dynamic process which aims to comply with the evolvement of knowledge and technology. However, the implementations of the reformed curriculum have been acknowledged to raise various issues. Likewise, among the issues related to the implementation of the Curriculum 2013, known as K13, in Indonesia was teachers’ difficulties, including mathematics teachers. This study aimed at investigating and describing the difficulties faced by junior high school mathematics teachers in implementing K13. The study applied a mixed-method approach involving 66 from a total of 78 junior high school mathematics teachers in Lhokseumawe, Aceh Province, as the study sample. The findings showed that 50%-60% participants encountering difficulties in components of training and socialization of K13, lesson planning, learning activities, and assessment and reporting the learning outcome. Although 93.94% teachers have taken the K13 training, only 56.45% of them sometimes implemented the curriculum in the classrooms. Additionally, the main resource of the difficulties was the ineffectiveness of training and socialization of K13 the teachers had attended. The teachers expected that there would be a learning community or forum as the follow-up action of the training, which can supervise the implementation of K13 in their classes. The directions for further research to improve curriculum implementation were discussed.
