Abstract

Dyscalculia is a mathematics learning disorder in children who have difficulty counting and calculating. Children who have dyscalculia will show difficulty in doing assignments involving numbers and mathematical symbols. Children with dyscalculia are unable to digest questions and do mathematical processes, or understand abstract questions. So children with dyscalculia cannot solve math problems like children in general. So that to overcome these negative impacts, with dyscalculous disorders can more easily understand and solve math problems.

Abstract

This study aims to see how the efforts in improving the mathematical problem solving ability of high school students by learning STAD type cooperative strategies. This research is based on the importance of mathematical problem solving abilities that must be possessed by students, but the reality on the ground that these abilities are still very low. This research is an experiment with a pretest-posttest control group design. This is done in order to find out how much improvement in the ability to solve mathematical problems taught by learning mathematics in STAD type cooperative strategies. For the experimental group, students are taught with STAD type cooperative strategies, while in the control group, students are taught by direct learning. The population of this study was high school students, while the sample was students of class XI IPA of Laksamana Martadinata Medan Private High School. Five classes were randomly selected, class XI IPA 3 class as the experimental class and XI IPA 1 as the control class. The instrument used in the form of problem solving problems. Based on the results of the analysis, it can be concluded that: 1) there is a mean difference between students who are taught with STAD type cooperative strategies and those who are in direct learning. 2) Improvement of students' mathematical problem solving abilities that get cooperative learning type STAD gets direct learning ineffective.

Abstract

AbstractEducation aims at person’s potency development process. Here, potency turns to competence. The competence is a mirror of person’s ability and skill for work. Teacher needs to know students’ talents, and smartness. The smartness is a reachable thing. Additionally, it is not only a thing person was born with, but it might be gained through supported situation like closed-relation communication.There should be free time and opportunity for students to develop their own sense, creation and practice. Accordingly, mathematic students should stand alone to study through their potency. Being a primary subject, mathematic is not simple subject to study. Therefore, mathematic teacher should be creative and innovative. In conclusion, the teachers should have good technique and method to improve students’ multiple intelligences based on local and social characters for nation character.

Abstract

Intelligence is the ability to act by a specific purpose, to think rationally, and to face the surrounding environment effectively. Factors that affect success of learning in affected by emotional intelligence. Learners who have high academic intelligence , they tend to have anxiety is unwarranted, overly critical, fussy, tend to withdraw, seemed cold and less likely to express frustration and anger appropriately. If supported by the low level of emotional intelligence, the leaner is often a source of  problems. When learners have a high IQ but low emotional intelligence level, it tends to be seen as learners stubborn, difficult to get along, easily frustrated, do not easily trust others, not sensitive to environmental conditions and tends to despair when experiencing stress. But the opposite condition experience by learners who have an average IQ level has a high emotional intelligence.
