<![CDATA[This study aims to determine the increase in the understanding of concepts and students ability at SMP Swasta Tarbiyah Islamiyah for the cube and beam through mathematical realistic approach. To find out how much improvement is obtained, students were given a test of understanding of concepts ability. Increased capabilities were first analyzed by using the normalized gain and processed by using two ways ANOVA formula. Two ways ANOVA formula is also used to determine whether an interaction between learning approach and students abilitiy to increase understanding of concepts skills. The results showed that (1) an increase in the understanding of concepts that students taught through mathematical realistic approach higher than understanding of concepts ability that students are taught only through ordinary learning, and (2) there is no interaction between the learning approach and the students ability to the improvement of students 'mathematical understanding of concepts ability.]]>

<![CDATA[Abstract. The purpose of this research is to know the understanding of mathematical concepts of students with the use of conceptual attainment model is better than the understanding of students' mathematical concepts with conventional learning. This research is quasi experimental research. The research design used was randomized subjects posttest only control group design. By selecting a Class VIII-2 sample as an experimental class and class VIII-1 as a control class of analytical techniques using the t-test as a hypothesis test, the prerequisite test is a normality test and homogeneity test. Based on the hypothesis test, t-test, obtained the price tarithmetic = 3.073 and price ttable = -1.997 at the real level of 0.05. Because tarithmetic ttable, so Ha accepted and H0 rejected. So it can be concluded that the ability to understand the concept of mathematics students using conceptual learning model attainment better than the ability to understand the concept of mathematics students using conventional learning model.Keywords: Concept Attainment, Understanding of Concept]]>

<![CDATA[AbstractThe research aimed study to determine: 1) the increasing ability of mathematics problem solving and student’s self regulated learning by using Differentiated Instruction is better than students comprehension convensional approach. 2) there was the interaction between learning by students first mathematic ability toward the increasing ability of mathematics problem solving and student’s self regulated learning. This kind of research is the quasi experiment. The populations of this research are all of the students in X grade of Tehnical High School 1 Percut Sei Tuan and the sample choosen is randomly sample which are Tehnical High School 1 Percut Sei Tuan contain with X TKJ1 as experiment class and X TITL1 as control class each consist of 24 students. Instrument used consisted of: (1) test studens first mathematic, (2) test problem solving and (3) self regulated learning scale. The instrument has been declared eligible content validity and reliability coeffesient of 0,809 dan 0,737 respectively for test mathematics problem solving and self regulated learning. Data analysis is done by using ANAVA two ways. The result of this research shown that (1) there increasing ability in mathematics problem solving and student’s self regulated learning by using Differentiated Instruction is better than using students comprehension convensional approach, (2) there were no interaction between learning and student’s ability level to the increasing ability of mathematics problem solving and student’s self regulated learning. The researcher suggests to use the Differentiated Instruction approach as the alternative way for teachers to increase the ability in mathematics problem solving and student’s self regulated learning.

<![CDATA[Abstract. This study aims to determine whether there are differences in mathematical problem solving abilities of students who are taught through an investigative approach and with conventional approaches in class VIII SMP 9 of Pematangsiantar. This type of research is experimental research. The population in this study were all eighth grade students of SMP 9 of Pematangsiantar as many as 8 classes. The problem solving abilities of students taught with an investigative approach to the average pretest of 57.73 and post-test of 85.42, the level of change in problem solving abilities was 27.69. Higher than the problem solving abilities of students who are taught with conventional learning the average pretest is 56.67 and posttest is 72.67. Hypothesis testing, from the calculation of student pretest data obtained at dk = 64 and the real level α = 0.05 and ????(1−12∝)=????0,975 obtained ttable = 1.669 and tcount = 1.172. Because tcount ttable = (1.172 1.669) it can be concluded that the initial ability of students is the same. While based on the calculation of student posttest data obtained at dk = 64 and the real level α = 0.05 obtained ttable = 1.669 and t count = 4.212. Because tcount ttable (4.212 1.669) then Ho is rejected and Ha is accepted. Then it was concluded that there were significant differences between problem solving abilities taught by an investigative approach and conventional approaches.Keywords: Problem Solving Ability, Investigative Approach, Conventional Approach.]]>
