AbstractUsing mathematics instructional media in schools is still very limited, this resulted in low levels of student understanding. One of the materials that concern is a probability in Class X. The solution for this problem is by providing instructional media on probability. The purpose of this research is to design valid and practical instructional media on probability material. This research is R & D (Research and Development) method and designing using ADDIE model which simplifies to ADD. The instruments are interview guides, validation, and practical sheets. Instructional media based on educational games at tenth grade has a percentage of validity 96.4%. Hence, this media is valid. Value of practicality on each level of ability, for students with high ability 95.3%, for students with average and low ability has the same value of 92.7% then this educational game is declared practice.Keyword: instructional media, RPG, ADDIEAbstrakPenggunaan media pembelajaran matematika di sekolah masih sangat terbatas, hal ini mengakibatkan tingkat pemahaman siswa masih rendah.

ABSTRAKOpsi adalah kontrak antara pemegang dan penulisÂ (buyer (holder) dan seller (writer)) di mana penulis (writer) memberikan hak (bukan kewajiban) kepada holder untuk membeli atau menjual aset dari writer pada harga tertentu (strike atau latihan harga) dan pada waktu tertentu dalam waktu (tanggal kadaluwarsa atau jatuh tempo waktu). Ada beberapa cara untuk menentukan harga opsi, diantaranya adalahÂ Metode Black-Scholes dan Metode Binomial. Metode binomial berasal dari model pergerakan harga saham yang membagi waktu interval [0, T] menjadi n sama panjang. Sedangkan metode Black-Scholes, dimodelkan dengan pergerakan harga saham sebagai suatu proses stokastik. Semakin besar partisi waktu n pada Metode Binomial, maka nilai opsinya akan konvergen ke nilai opsi Metode Black-Scholes.Kata kunci: opsi, Binomial, Black-Scholes.ABSTRACTÂ Option is a contract between the holder and the writer in which the writer gives the right (not the obligation) to the holder to buy or sell an asset of a writer at a specified price (the strike or exercise price) and at a specified time in the future (expiry date or maturity time). There are several ways to determine the price of options, including the Black-Scholes Method and Binomial Method. Binomial method come from a model of stock price movement that divide time interval [0, T] into n equally long. While the Black Scholes method, the stock price movement is modeled as a stochastic process. More larger the partition of time n in Binomial Method, the value option will converge to the value option in Black-Scholes Method.Key words: Options, Binomial, Black-Scholes

This research is motivated by the importance of students 'mathematical understanding, but the fact is that students' mathematical understanding is still low in working on algebraic form questions. This problem brings out a learning obstacle, where students cannot interpret the algebraic form elements and cannot operate the algebraic form. This study aimed to design a didactic design phase using fables based on students' mathematical understanding. The research method is descriptive qualitative research. Design is Didactical Design Research (DDR) with 15 junior high school students as subjects. The data was collected using triangulation techniques, then analyzed descriptively. This study results in a didactic design in the form of a situation that can anticipate students' learning obstacles in algebraic form material and facilitate students' thinking process. Situations are created using exciting pictures and stories to motivate student learning. The results show that the situations that have been created make it easier for students to group similar and dissimilar terms and can operate the algebraic form easily and algorithmically. The students also can interpret the elements of the algebraic form along with addition and subtraction operations in the algebraic form based on the understanding of each student.

This study aims to determine the ability of reflective mathematical abstraction which consists of the ability to apply concepts, the ability to make relationships between concepts to form new meanings, and the ability to manipulate abstract mathematical objects. This research is a qualitative research with type of case study. The sample used in this study was one senior high school student of class X. The method of collecting data to find the results of the study was to use a test instrument for building questions and interviews. These instruments are validated first using Expert Judgment Validation. The results obtained by indicator one and indicator two, student still find it difficult to understand the concept and choose which other concept is suitable to obtain a solution. Meanwhile, on the third indicator student can manipulate abstract mathematical objects. So that the student' mathematical abstraction ability is still quite good.

An option is a contract between a holder and a writer in which the writer grants the rights (not obligations) to the holder to buy or sell the assets of the writer at a certain price (strike price) at maturity time. Asian options are included in the dependent path option. This means that Asia's payoff option depends not only on the stock price at maturity time, but it is the average stock price during its maturity and symbolized A (average). Monte Carlo is basically used as a numerical procedure to estimate the expected value of pricing product derivatives. The techniques used are the standard Monte Carlo and variance reduction. The result obtained the Asia call option price and put for both techniques with 95% confidence interval. The variance reduction technique looks faster reducing 95% confidence interval than standard method.

In learning process, students are currently cannot be separated from learning difficulties, including the study material algebra limit function. It because the level of students' mathematical understanding regarding the material is still quite low. This study aimed to analyze the barriers to student learning, designing learning materials based on the material mathematics understanding algebra limit function is valid, determine teacher intervention during the implementation of learning materials and to analyze barriers to student learning after the implementation of learning materials. This research is a qualitative research study design using the form Didactical Design Research. Stages of research conducted: 1) analysis of the situation didactic before learning, 2) analysis of metapedadidatik and 3) the retrospective analysis. Data collection techniques used were tests, interviews, questionnaires, and documentation. The instrument used was a matter TKPM (Comprehension Mathematical Ability Test), interview, validation sheet materials, and documentation guidelines. Research results obtained are students experiencing obstacle to learning the material limit algebra functions. These obstacles are 1) students' difficulties in relating the material prerequisites to limit problems. 2) students can not write properly limit symbol, 3) students can not apply a limit theorem, 4) students are not able to determine the limit value at one point, and 5) students cannot determine the value of the limit at infinity. Learning materials that have been made have validation level of with very valid criteria. The response was given when the student intervention, generally in accordance with response prediction so that interventions carried out in accordance with the design that has been made. After learning materials student learning obstacles implemented reduced/minimized.

This research motivated by the low of students’ mathematical problem-solving ability and the utilization of learning media based on technology that was not maximum. Preparation of learning materials in the form of the interactive digital module was one of the ways can overcome that problem. The method that used in this research was RnD with the design model ADDIE that was analysis, development of implementation design and evaluation with the restrictions of not doing the implementation stage. The instrument of collecting data in this research was the form of validation and the form of practicalities of the user senior high school students that has to get the material of linear inequality absolute value. The data that was taken though with statistics descriptive way. The validation result of the digital module gets ratings in the amount of 83,33% from media expert and 85,57% from a material expert. This interactive digital module was decent to use and very practical with the average percentage for students’ high cognitive ability 88,77%, medium 89,49%, and low 82,97%. Whereas the other user that was mathematics teacher give the percentage 84,78% so, according to them this digital module was very practical.
