Abstract

This study aims to determine: (1) to increase mathematical problem solving ability of students through the application of problem-based learning, and (2) to increase active activity levels of students with problem-based learning. This type of research is a class action. Subjects in this study are students of cass VII-3 SMP Negeri 7 Padangsidimpuan. The instrument uses a form of problem-solving ability test descriptions and observation. The results show that in the first cycle has not show optimal results therefore it needs the second cycle. In the  second cycle shows an increase in the problems solving ability of students. In the first cycle is 50% rising to 89% in the second cycle. The levers of active student’s activity based on the observation shows at each meeting including both categories. Based on these result, the researcher suggests that the problem-based learning can be an altervative for teachers of mathematics to be developed as one of the effective learning to improve students’ mathematics problem solving ability and increasing the activity of active students.

Abstract

Crisis in Indonesia is getting messy is believed to be due to a lack of character. Indeed, many feel that this national has lost its character. But when asked what the character was, we sputtered. Character, something that should be know, but most do not want to know. Something ver important, but most of us underestimate, something that is very necessary, but in the fact most of us even laughing. Awareness of various circles, especially educators are expected to instill character in every educational institution, given the character of the nation that has decreased or away from the values of kindness.

Abstract

Mathematicts is an important subject at Elementary Schools. Preliminary observation at many Elemmentary School indicated that student’s mathematic achievement was not satisfactory. The student’s understanding of number operations was olso low. One of many ways to improve the student’s activities and mathematic achievement is through the use of block Dienes in teaching number operations.

Abstract

The purpose of this study  is to investigate and to describe the gain of students’ mathematical understanding ability through mathematics teaching and learning by using dynamic geometry software, Geogebra. This study uses a not equivalent control group design, that is control group and experiment group. Direct instruction is implemented in control group otherwise mathematics teaching and learning with using Geogebra is implemented in experiment group. The population of this study are allof junior high school students, the subject are two groups of seventh grade students and the object is studentss’ mathematical understanding ability. The sample is choosed with using purposive sample technique. This study use mathematical understanding ability test that analysed quantitatively into post-test and normalized gain of students’ mathematical understanding ability between the two groups. The analyse of the data result will answer the hypothesis, students’ understandingability who has studied and learntwith using Geogebra is better than students in direct instruction class.

Abstract

The aim of this research are: (1) to find out the improving competence of mathematical connection and student’s creative thinking through open ended learning and usual learning, (2) to find out there was the interaction between learning and fist mathematical competence toward the improving competence mathematical connection and student’s creative thinking. This kind of research is the quasi experiment. The populations of this research are the students in eleventh grade of SMP Muhammadiyah 03 Medan. The sample chosen random sample which are VIII, as experiment class and VIII, as control class. The instrument is validated first, and the result is shown that (1) to test the competence in mathematical connection is valid with the high criteria, on other hand to test Student’s creative thinking competence is valid with the high criteria. (2) Coefficient reliability to test mathematical connection competence is 0,73 with the high category, on other hand reliability to test student’s creative thingking competence is 0,79 with the high category. Data analysis is can rid by using ANAVA two ways The result of this research Revealed that (1) there was improment competence in mathematical student’s creative thinking by using open ended learning is better than using usual learning, (2) there no interaction between learning and student’s competence level to the improment competence of mathematical connection and student’s creative thinking. The research suggests: (1) to use open ended learning as the alternative way for teachers to improve the competence in mathematical connection and student’s creative thinking. (2) learning tools is prepared well and suited with the indicator of competence and time allocation that must be reached, (3) must be selective in choosing the material of learning by using open ended learning because not all materials of teaching is suitable to apply by using open ended learning.

Abstract

Intelligent factor is the most important of human personality, because intelligent take a part in each human activity, specially low or high student’s attainment in learning process. Many influencing factors of someone ability in problem solving. The aim of this researce are to know how the correlation between double intelligent with learning result in math subject about algebra.This research conducted in MTs N  2  Padangsidimpuan at VII. Grade Collecting data done by questionnaire and learning test result. To collect the data about intelligent researcher use questionnaire and test  used to collect the student test result. While to test hypothesis. Researcher use correlation product moment, and t-test to see significant or not.Based on research, researcher can conclude there is a significant correlation between, double intelligent with learning result in math subject about algebra in MTs N 2 Padangsidimpuan at VII Grade. Its mean more intelligent kind students have, higher math subject that reach by students.

Abstract

Formative assessment is the evaluation conducted at the end of the discussion of a subject/ topic, and is intended to determine the extent to which the learning process has been running as planed. In assessing the formative test a science teacher in the learning process must run in certain situations. Therefore in the learning process students should have early knowledge base or IPA as a condition for getting Knowledge to a higher level. With prior knowledge of the students in science teaching and learning process, the teacher can assess the results of their study. From the results of this evaluation will be obtained picture of anyone who has been successful and who is considered to have not managed to take further appropriate actions. Learning outcomes that occur because of changes in student behavior that can be observed and measured in terms of changers in knowledge, attitudes and skills. In learning science learning outcomes can be measured by the ability of the students themselves gain knowledge about the natural environment, develop skills, insight, and awareness of the technology in relation to their use for everyday life.

Abstract

In general the low learning achievement of students due to the problems that arise in the learning process. Seeing the reality of it is one of the important agenda for the teacher is to create is to create a learning environment in math. The achievement of learning achievement required an appropriate delivery methods that aim can empower students, both in terms of academic and social skills, and in the end students got knowledge, can understand the concepts being taught, and students can solve the problem with an open nature,  so that the porpuse of education can be achieved. Guide of note taking method is the correct method to improve students achievement in math. Guide note of taking method is a method that as fairly simple and fun which are used to aid students in making notes or important points when delivering course material will be provided.
