p>The connection between mathematics and the application of mathematical concepts affects all aspects of daily life. Because of the connection between mathematics and the real world through mathematical models, mathematical modelling may help students in understanding this relationship. In the context-based Asesmen Kompetensi Minimum (AKM) problems...

While problem-posing respecting real-world situations can be a promising approach for fostering modelling competence, research on modelling through problem posing is scant. This present paper aims to characterize the mathematical tasks designed by prospective teachers regarding the criteria of a modelling problem. Data were collected from fifty mat...

This study aims to describe the process of developing and producing an assessment book for the Mathematics Education Study Program that is valid, practical, effective and ready to be used for assessment lectures. This is a development research. The subjects of this research are assessment lecturer and students who are joining in assessment lectures...

Students are often found dilemmatic when constructing an integral form of a calculus problem. This is a descriptive-explorative study aiming at investigating college students’ preference for constructing integral form of area-related problem. Data were collected from 63 responses of college students who were taking an Integral Calculus course at a...

The use of digital resource for learning has been increasing since the Industrial Revolution 4.0 was enlivened. This was further strengthened by the government’s policy to learn from home since the COVID pandemic 19. Various types of online learning can be effective but also sometimes do not succeed in achieving the expected learning goals. Drijver...

Learning design is one of the factors that support the learning process in order to achieve learning objectives in all subjects including mathematics. Many approaches can be employed by a teacher in making learning design, one of which is rigorous mathematical thinking (RMT) approach. The RMT approach puts forward students actively in constructing...

Varicella is a disease caused by the varicella-zooster virus. This disease is common in children under 10 years of age and is not a fatal condition. However, some cases of varicella in adults are more dangerous because they can cause pneumonia. Here, discussion about analysis of varicella epidemic model is presented. This model is expressed in the...

An Employee stock option (ESO) is one of compensation that given by company to their employee. It gives right to the employee to buy companies stock in the future with special price that have been agreed when the options were granted. In general, the valuation of ESO pricing is different with other option pricing. ESO have some features which accom...

Covid-19 is a very extraordinary case not only in one country but all countries in the world. The number of deaths caused by Covid-19 is very large and the rate of spread of this disease is very high and fast. In this paper, we perform an analysis of a covid-19 epidemic model. This model is a development of the SEIR model in general which is equipp...

Graphing ability facilitates students to understand and to connect graphs of data with real-world situations. This ability related to mathematical competencies such as logical thinking and visual representation. One aspect of graphing ability that is important for the student to get meaning from the graph is the interpreting graph. The purpose of t...

Creating a problem is one cognitive process of Bloom’s taxonomy. By making a problem and the answer on their own, causes students to understand more complex context problems. Applying number sequence challenges students to apply higher-order thinking skills and emphasize exploration, investigation, conjecture, and generalization. From the previous...

Chagas disease is a parasitic infection caused by protozoan Trypanosoma cruzi which is transmitted to human by insects of the subfamily Triatominae, including Rhodnius prolixus. This disease is a major problem in several countries of Latin America. A mathematical model of Chagas disease with separate vector reservoir and a neighboring human residen...
