Abstract

Differential equations are mathematical equations for functions of one or more variables, which relate the value of the function itself and its derivatives in different order. As a prospective teacher, students are required to master the cognitive domain of differential equations. Based on the observations made where tested the initial knowledge of students in the course of differential equations and found 80% of students are not biased deserve to be said to pass. Therefore, this research is aimed at 1. Developing instructional of differential equations based on brown model and cooperative learning model as a tool in learning process; 2. Testing the effectiveness of teaching materials of developed differential equations; 3.Test whether there is a good improvement in learning outcomes in the teaching and learning process using the teaching aid tool. The method used in this research is development research. From this result Researchers believe that in the course of teaching materials is very effective tool process of course in the classroom. Keywords: Course Tools, Differential Equations.

Abstract

In this study the background to the problem is the low student learning outcomes in the Theory of Opportunities course. Opportunity theory is a course where students must master terminology, concepts, principles, algorithms and languages ??or the essence of a story problem. To be able to solve mathematical story problems, it is obligatory to master the five components. The purpose of this study is to determine where misconceptions are often experienced by students in understanding the essence and problem solving of probability theory stories, as well as any factors that hinder the learning process of opportunity theory courses outside the five components. The research subjects taken were mathematics education students in the odd semester of the 2018/2019 school year. Data collection techniques and methods used are the method of observation, interviews, documentation, and tests. The results of this study indicate that there are 41% do not master the terminology, the concept of 44.7%, prinsisp 47.8%. Algorithm 51%, and language / conclusion drawing 52%. There were 12 questions that were tested and the average student who could answer haya was around 51% and those who were still experiencing misconceptions were 49%. Algorithm and conclusion drawing are one where many students experience misconceptions in solving the problem story theory questions. Keywords : Misconception of probability theory, Misconception Analysis

Abstract

The research method used is descriptive qualitative. Collection of primary data and secondary data. Analysis with data reduction, presentation, conclusion and verification. Research at SMA Yadika 11, SMK 4 and SMA 7 Bekasi. The results of the analysis, 1) 95% of the online learning process is still from curriculum 13, the school facilitates teachers. However, when the implementation was not in line with expectations, this was because the material provided was not prepared with the standard of the initial ability of students, the books provided were not strong enough to build concepts, educators had difficulty writing symbols, student responses to professional competence were 79%, 70% of participants students assess that teachers do not have teaching materials and modules used as learning aids, observing 4 teacher materials have difficulty explaining related to writing symbols and proof. 2) The form of readiness by providing textbooks as the main source, however, books with cognitive dimensions. Lots and not hot books, this is not in line with curriculum 13. 3) The assessment method is prepared by the teacher, however, the assessment method is not given and the material tested is more difficult than what is taught and 60% disagrees with the teacher's assessment method.

Abstract

The daily test results for student of class VII.2 SMPN 58 Jakarta on the Comparison material showed that 30 out of 36 students got scores below the MCML (Minimum Criteria of Mastery Learning). The low test results were not always caused by the level of students’ intellegence, but it could occur because students have difficulty learning, as a student with difficulty learning do not necessarily have inadequate intellegence. The research aimed to determine the type or form of learning difficulties and the causes for students during their learning. The research used qualitative method with a descriptive qualitative approach. The population in this research were 30 students of class VII.2 SMPN 58 Jakarta who got daily test scores below the MCML for Comparison material. The interview subjects were 6 out 30 students who were selected through purposive proportional random sampling, and a Math teacher in this class. The results obtained based on the test analysis and interviews found student difficulties, such as in interpreting language, in unsderstanding and using concepts, in using data, and in technical difficulty (counting). Then, the results obtained based on the anlysis questionnaire analysis and interviews found that students had difficulties due to their lack of confidence and mortification in learning, and teacher who didn’t understand each student personally.
