Abstract
Current learning encourages students to have excellent critical thinking skills. The teacher tries to apply various kinds of learning strategies and also appropriate learning media in order to facilitate students to achieve competencies. In this effort, internet-based technology has an important role as a learning management system, learning apparatus, and simulation for certain phenomena. This study examined the level of success of learning that utilizes the learning management system (Schoology) using the hypothetical-deductive strategy and enriched with the simulation of physical phenomena (PhET Simulation). The learning syntax was validated first by experts before applied to students. At the end of learning, students were given a usability questionnaire (USE Questionnaire) to determine their level of acceptance of this learning strategy. These results formed the basis for implementing this strategy on broader schools.

Abstract
Pedagogical Content Knowledge (PCK) is inseparable from the part of the teaching and learning process. As a prospective teacher-student, an understanding of PCK is needed to be able to interpret the learning process appropriately. The purpose of this study was to determine the perceptions or responses of prospective teachers about PCK and its application in the learning process. The research respondents consisted of 54 students of Mathematics Education from one of the universities in Bandung, West Java to fill out an online survey. The questionnaire in the form of a survey contains ten indicators of pedagogic knowledge, four indicators of content knowledge, and seven indicators of pedagogical content knowledge, and four cases that often occur in learning to be asked for solutions from respondents. Data from the questionnaire was processed and analyzed descriptively. The results of the online survey showed that only 33.3% of respondents had heard the term PCK, so 94.3% of respondents stated the importance of PCK to be known and understood by prospective teacher. Although the term PCK is not familiar to respondents, almost all of its indicators are often used and studied. The right solution is suggested by respondents for each case of learning problems. In this case, it is stated that PCK is a complex process in the learning process, where educating knowledge and skills must together in order to achieve the expected goals in learning.

Abstract. HOTS is the important concept in Indonesian curriculum 2013 reform. Combinatoric is one of the mathematic-s branch that can give an experience to the students to increase their HOTS. One of research topic in combinatorics is the rainbow connection number of a graph. Let G=(V,E) be a nontrivial connected graph on which is defined a coloring c:E(G)→{1,2,3,… ,k},k ∈ N, where adjacent edges may be assigned the same color. A path u-v in G is a rainbow path if all edges in the path have different colors. In this case, the coloring c is called a k-rainbow coloring of G where k is the number of color used. The minimum k for which G being rainbow-connected is called the rainbow connection number rc(G) of G. If for every pair u,v ϵ G, G contains a rainbow u-v geodesic, then G is called strongly rainbow-connected. The minimum k for which G being strongly rainbow-connected is called the strong rainbow connection number src(G) of G. In this paper we determine the exact value of rc(G) and src(G) for grid-3D graph.

Abstract
Abstract. One of the biggest calls for educators to take part in the 21st century learning is to make sure students equipped with creative thinking. To empower these skills, a variety of effective learning models can be implemented. The current study aimed to develop a learning model that has the potential to improve students- creative thinking by integrating Problem-Oriented Project-Based Learning (POPBL) and Student Team Achievement Division (STAD), hence called POPBLSTAD. Plomp design was used as the procedures for developing this product. It consisted of a preliminary investigation, design, realization/construction, test, evaluation, and revision. The model was examined through a quasi-experiment. The participants- creative thinking was evaluated based on five indicators: fluency, originality, elaboration, flexibility, and metaphorical thinking, using an essay test. The POPBLSTAD learning model was confirmed valid with a score of 3.47. The results of the ANACOVA analysis showed that the implementation of POPBLSTAD improved student creative thinking significantly. This finding suggests that POPBLSTAD can be used as an alternative learning model that is effective to refine student creative thinking.

Abstract
The aim of this study was to investigate relationship between reversible reasoning and conceptual knowledge, particularly, mental action deployed by undergraduate students through reasoning reversible in problem situation of composition of function. This case study compares reversible reasoning of three three high-achieving undergraduate student. These students were tested before with test measuring their understanding of aspect function. Data collected through think aloud and clinical interviews depict strategies that the participants used to work back to find original function. The result showed that constructing reversible reasoning requires conceptual knowledge with several characteristics (relational-harmonic, relational-visual, relational-pseudo) that explored in detail. Suggestion for further inquiry on improving knowledge about reversible reasoning as mental valuable tools for students in classroom practice.

Abstract
Deaf students- hearing problem results in their mastery of language and mathematics lower than hearing students. Learning the topic of rounding is difficult for deaf students because it requires a good understanding of language and a true perception in math concepts, in which are abstract in nature. Learning concepts needs a special strategy for this type of students, as generally mathematics is difficult to be translated and communicated by sign language. This specificity forces them to possess unique behavior in understanding everything through visual power. This paper discusses a study of the creation of a book and smartphone applications as devices based on augmented-reality (AR) software on the topic of rounding accompanied by rich visualization to facilitate deaf students in achieving mathematical basic competencies. This study aims to describe and reveal the validity and the effectiveness of designed devices through their implementation in a classroom. The research and development method with ADDIE model is used in this study consisting of five stages, namely: analysis, design, development, implementation, and evaluation. The results of this study show that the AR-Book and the AR-Smartphone application are valid used by deaf students and both devices are effective in achieving their mathematical basic competencies.
