This article studies designing an interactive learning media based on a mathematical modelling framework. This article only discusses the preliminary stage or the initial stage in developing interactive learning media using design research. The preliminary stage covers two steps; there are analysis and design steps. The analysis step focused on analyzing students' difficulty in solving real-world problems and analyzing the curriculum. The design step focused on the initial design of interactive learning media that use six principles for developing mathematical modelling problem by Catherine Paolucci.

Humanity has dealt with pandemics or plagues throughout history. History also demonstrates that in periods of uncertainty there are always guides that remain certain. In response to Covid-19, the Indonesian government’s ‘New Normal’ provided a list of challenges for all educators, who must then adapt their resources and pedagogical strategies to meet these challenges. Yet, from the ‘Old Normal’ what remains a certainty for educators amongst all the chaos of pandemic change? This paper discusses the pedagogical norms that research has provided regarding the teaching and learning process for mathematics at all levels. It argues that these norms provide certainty for educators in their planning and delivery irrespective of resources, context, or online capacity. It is by following these norms that educators will improve mathematics skills for ‘New Normal’ education. Whether the responses to the New Normal are to become successful depends greatly upon the adaptability and dedication of these educators, who should be regarded as ‘super heroes’ or ‘national treasures’.

A smartphone-based evaluation media learning management system (S-LMS) is an application that supports teaching and learning activities and online evaluation. S-LMS media is the development of conventional evaluation media using smartphones and internet networks. The purpose of writing this article was to determine students' perceptions of the smartphone learning management system (S-LMS) based quiz in public high school students at Serang City. Through a qualitative descriptive method by providing questionnaires and interviews with students, the data were analyzed to obtain a description of the students' perceptions. Overall, 85.83% of students are interested in using S-LMS-based evaluations, in accordance with expectations as many as 82.78% of students are able to understand the material discussed because of the discussion in each quiz. In addition to this, students were actively involved in participating in evaluation and learning, as many as 86.94% of students were happy and followed carefully every evaluation activities.

Let Zk , k > 1, k ∈ N be a commutative ring with unity, polynomial f = a0 + a1x + ⋯ + anx n ∈ Zk[x], ai ∈ Zk. We can construct c(f)= 〈a0, ... , an〉 be an ideal of Zk generated by a0, ... , an . If (a0, ... , an) = 1 or ai unit of Zk for i = 0, ... , n, then c(f) = Zk, for k composite.. For k is prime, because all of the elements in Zk is unit, then c(f) = Zk, for every f ∈ Zk[x].

This study aims to describe the early mathematic skills of preschoolers in the understanding division through the idea of “fairness". The idea of fairness was familiar to children before the division was first encountered formally. The subjects in this study were three children aged 3-5 years. Based on the research results, it is found that children aged 3-5 years already have an initial understanding of the division. This understanding is identified through what is known as 'fair sharing.' Their perception of division can be seen from the subjects' responses and expressions in “fairness” and “equal sharing” activities.

In this paper, we consider to analyzed the mathematical reasoning ability of students in solving mathematics problem based on Higher Order Thinking Skill (HOTS). The method of this research is qualitative descriptive. This research consisted of 12 subject. Based on the analysis that mathematic reasoning ability of students can be grouping into 3 categories, that are low, moderate and high groups. The results showed that 16.7% of students were categorized as having low reasoning, that is presenting a mathematical statement in writing, 16.7% of students were categorized as having moderate reasoning, that is able to make a conjecture and perform mathematical manipulation, and 66.7% of students were categorized as having high reasoning, which is able to make a conjecture, to perform a mathematical manipulation, to provide the reasons or evidence for the solution and drawing a conclusion.

In mathematics and mathematics education, ranges of application are sometimes generalized. This article studies the generalization of the concept on internally dividing points. The ratios of internally dividing points are usually considered in real numbers since the real numbers are naturally corresponding to the length of line segments. The aim of this article is to extend the range of such ratios into the complex numbers. After defining the complex-valued ratio, we shall apply it to the generalization of Menelaus’ theorem which is famous in elementary geometry.

This article discusses the analysis of dynamic models of the spread of drug addicts with educational effects. This model is modified from the White and Comiskey model by adding populations that have stopped using drugs so that the model will form the type of SURS. Besides, modifications were also made to consider the educational effects in each population class. The analysis shows that the free equilibrium point of drug addicts is stable when the condition is R0 < 1 and the endemic equilibrium point is stable when the condition is R0 > 1. Numerical simulations show that an increase in the rate of education can reduce the rate of distribution of drug addicts so that the spread of drug addicts gradually decreases and will disappear from the population.
