The Covid-19 pandemic that has hit Indonesia poses a challenge for educators to find effective and efficient alternatives to distance learning. Therefore, this study aims to develop distance math learning devices using the PQ4R (Preview, Question, Read, Reflect, Recite and Review) learning strategies that are valid, practical and effective. This type of research is development research that uses the Plomp development model. This research was conducted at SMPN 1 Duduksampeyan Gresik in the 2021/2022 academic year. The learning devices developed consist of lesson plans and worksheet on the set material.The development phase consists of an initial investigation phase, a design phase, a realization or construction phase and a test, evaluation and revision phase. Data collection methods used are tests, observations and questionnaires. The data were analyzed using the formula for the average value and the percentage was then classified according to the established criteria. The results of data analysis show that distance math learning devices using the PQ4R learning strategies are in the valid, practical and effective categories. This can be seen from the average validity of the lesson plan and student worksheet of 3.78 and 3.87, respectively. While the average practicality of lesson plan and student worksheet are 3.93 and 3.92, respectively. The implementation of the syntax of learning mathematics is included in the very good category with a percentage of 100%. The response of students after participating in the lesson was very positive. Student learning outcomes are included in the very good category with a percentage of completeness of 90.63%.

This study aims to describe the process of generalizing number patterns in solving mathematical problems based on visual, auditory and kinesthetic learning styles. The subjects in this study were three grade VIII students of SMP Muhammadiyah Limbung with visual, auditory and kinesthetic learning styles. Data collection was done by giving a learning style questionare and a generalization test of patterns and interviews. This research is a qualitative research. The data were analyzed by means of descriptive and classification. The results showed that research subjects who had visual learning styles were able to perform better problem-solving stages than audio and kinesthetic learning styles. This is because the visual learning style has the nature of reading or understanding written instructions which results in the visual learning style being able to code and process information well and regularly.

So far, mathematics is still considered a complex subject to understand. Thus, mathematics learning outcomes in this subject are generally relatively low. Therefore, researchers want to conduct an assessment of the problems faced by students in learning mathematics. The purpose of this research is to know whether or not there is an influence of learning variables, the environment in which students learn, the motivation of students in learning, and the independence students on their learning outcomes. The method chosen is a survey with the snowball sampling method on high school students. The analysis is used in multilevel linear regression analysis. This is doto to obtain or explore more information from the modeling analysis carried out. Based on the research, it was found that there were simultaneous significancenificant simultaneous student’s mathematics learning outcomes. On the other perception, it is also seen that the variability of the grade level is very low which is described as the problem faced for each grade level is not much different.

Fuzzy Clustering is one of the five roles used by data mining experts to transform large amounts of data into useful information, and one method that is often and widely used is Fuzzy c-Means (FCM) Clustering. FCM is a data clustering technique where the existence of each data point in the cluster is based on the degree of membership. This study aims to see the pattern of data samples or data categories using FCM clustering. The analyzed data is stock data on Jakarta Stock Exchange (BEJ) in the Property and Real Estate sector (issuer group). The data mining processes comply Cross Industry Standard Process Model for Data mining Process (Crisp-DM), with several stages, starting with the stage of getting to know the business process (Business Understanding) then studying the data (Data Understanding), continuing with the Data Preparation stage, Modeling stage, Evaluation stage and finally the Deployment stage. In the modeling stage, the FCM model is used. FCM clustering model data mining can analyze data in large databases with many variables and complicated, especially to get patterns from the data. Then a Fuzzy Inference System (FIS) was built based on a known pattern for simulating input data into output data based on fuzzy logic. Keywords: Fuzzy c-Means Clustering, Pattern Recognition
