Semiotics is simply defined as the sign-using to represent a mathematical concept in a problem-solving. Semiotic reasoning of constructing concept is a process of drawing a conclusion based on object, representamen (sign), and interpretant. This paper aims to describe the phases of semiotic reasoning of elementary students in constructing the properties of a rectangle. The participants of the present qualitative study are three elementary students classified into three levels of Adversity Quotient (AQ): quitter/AQ low, champer/AQ medium, and climber/AQ high. The results show three participants identify object by observing objects around them. In creating sign stage, they made the same sign that was a rectangular image. However, in three last stages, namely interpret sign, find out properties of sign, and discover properties of a rectangle, they made different ways. The quitter found two characteristics of rectangular objects then derived it to be a rectangle’s properties. The champer found four characteristics of the objects then it was derived to be two properties of a rectangle. By contrast, Climber found six characteristics of the sign and derived all of these to be four properties of a rectangle. In addition, Climber could determine the properties of a rectangle correctly.

The present study is aimed to describe the development of an innovated learning for the disabled students in higher education. The development of learning innovation was performed by developing a learning model, that is what so-called Universal Design model (DUE). The method implemented to develop the model was Research and Development). This method constitutes several stages, among others: 1) needs analysis, 2) gathering information, 3) designing a product, 4) validating the product, 5) revising the product, 6) trying out the product, 7) revising the product, and 8) consolidating the product. The result of the research shows that the produc, in this case is DUE learning model, has met the criteria after going through several tests from the experts, thus valid.

In the people of South Jember, especially in Wuluhan District, activities that cannot be separated from mathematics are buying and selling, farming and building houses. One of the interesting activities that also use mathematics in the field of agriculture, namely the determination of cabbage planting patterns. Based on the results of interviews with cabbage farmers in Wuluhan District, the cabbage planting pattern is regulated by pay attention of sunlight, irrigation, and ease of maintenance. So that there is a size and distance that must be regulated on the land when planting cabbage. This type of research is qualitative. Data collection technique used are observation, interviews, and documentation. This study was analyzed using the Nasution Circular model namely by reducing data, displaying data, and drawing conclusions. The results of this study are (1) the line spacing used is at least 60 cm; (2) the minimum distance between cabbage is 50 cm; (3) the cabbage planting hallway at least 80 cm; and (4) the distance of the cabbage plant from the edge of the land at least 60 cm. The distance is determined and is used by farmers as a condition for the cabbage plant can grow optimally. The size is determined by considering irrigation factors, ease of maintenance, and maximization of fertilizer absorption.

A context with Islamic values lies in can be used as a starting point in learning mathematics. The challenge is how teachers can deliver, formulate, and connect the mathematical content and the Islamic values in the learning activities. One of the learning approaches that can solve that challenge is Realistic Mathematics Education (RME) by implementing context as one of the activities. This study aims to design hypothetical learning trajectories (HLT) for supporting students in learning the rules of enumeration with the RME approach based on Islamic values. This study uses the first phase of design research (DR) methods. The first phase, namely preliminary design. The HLT is developed in this phase and will then be tested on students in experimental design, and the implemented results are analyzed in the retrospective analysis. Researchers began the study with a literature review, then obtained data about students' difficulties in the enumeration (counting) rule. Based on the review, researchers formulated activities into learning procedures and expected students and teachers’ responses, called HLT. The HLT of enumeration rules on data content with RME based on Islamic seen from the perspective of the four emerging modeling levels. At the first level – the 'situational level' – students explore the realistic context of determining the possible route to the mosque. The second level is the 'referential level' where the selection rules are used as a starting point for learning the concept of probability. At the third level – the 'general level' – students use diagrams to generalize the possible outcomes of an experiment and develop an understanding of multiplication rules. Finally, students develop their informal knowledge at the 'formal level' into formal concepts of multiplication rules.

This study aims to figure out how percentage bar supports students in solving percentages problems: 1) students are able to compute the part of a whole while the percentage is given; 2) students are able to compute a whole if its part and its percentage is given. The subject of this research is 22 fifth grade students. The study is conducted when students only have pre-requisite knowledge of fractions.According to the aims, we use Design Research as a method by developing a set of instructional activities which is exploring students’ knowledge of percentages. Besides, we apply some contextual problems – road repair and discount problems – based on Realistic Mathematics Education (RME) approach. From those activities, students employ percentage bar to solve percentage problems. The collected data shows that the percentage bar can support students in solving percentage problems. However, some of them still have much struggle in solving discount problems.
