Abstract

The purpose of this research is to know which ability of creative thinking of mathematic learners better between using Problem Based Learning (PBL) model and Discovery Learning (DL) model. The research method used is experimental research method. Based on the results of research and data analysis, researchers then use the Mann-Whitney Test (U) to examine differences in learning outcomes. From the calculation results obtained value of U = 427,5. Since there are several twin numbers then correction of standard deviation is then used to find the value of z. The value of U is first converted to z value because the research zhitung = 2,93 while ztabel at a significant level of 0,05 is 1,96. When consulted in table z, the z-value is outside the reception area H0. This is because the test used is a one-party test with acceptance criteria is accept H0 if and reject H0 in other situations. As we know that the value of zhitung > z0,475 then accept H1, that is there are differences in the ability of creative thinking mathematic learners using Problem Based Learning model using Discovery Learning model.Student's response to Problem Based Learning model is quite good. If we accumulate 52,6% student answer show response strongly agree and agree that we can translate as positive response, 19,78% neutral response and the rest only 27,61% student disagree and strongly disagree what we mean as negative response.

Abstract

Application of Hypnoteaching Method to imrove Communication Skills Mathematical Student. This study aims to determine students’ mathematical communication skills before and after learning mathematical with Hypnoteaching Method. Pretest data analysis results obtained value tcount = −1, 26 , while at the 0,05 significance level and 40 degrees of freedom, obtained value t(0,975)(40) = 0,021 because -2,021 < -1,26 < 2,021 or − < < t t t table count table then Ho is accepted, it means not different as significance between mathematical communication skills early experimental class and mathematical communication skills early control class. While the posttest analysis result obtained value tcount = 2,632 , while at the 0,05 significance level and 40 degrees of freedom, obtained value t(0,95)(40) =1,684 because 2,632 > 1,684 or t t count table > then H1 is accepted, it the ability of students mathematical communication use Hypnoteaching method is better than students mathematical communication who use conventional learning. In addition, the result of the test analysis gain obtained zcount = −6,7 and z z table = = 0,45 1,64 . Because -6,7 < 1,64 then H0 is accepted and it means the experimental students’ ability of mathematical communication isn’t on the high level.

Abstract

Mathematics is a branch of philosophy. Its development is influenced by the results of human thought, so that the progress of a civilization becomes an implication of the results of these thoughts. The coming of Islamic teachings through the Messenger of Allah as a messenger of Allah SWT had a huge impact on the Arabian people at that time. Even the development is expanding to Europe and Asia. The spread of Islamic teachings throughout the world, giving birth to reliable thinkers, became the forerunner of the development of science, including mathematics. This research, provides an overview of how mathematics developed, and applied to the progress of civilization at that time. In addition, the literature study of the concepts of chemistry has been compiled by Muslim mathematicians at that time. In this case, it focuses on how arithmetic is discussed by Muslim mathematicians al-Uqlidisi about the concept of arithmetic.

Abstract

This study aims to examine in depth about the ability of students 'mathematical representation and its improvement using the Somantic, Auditory, Visualization, Intellectually (SAVI) learning model, and to determine students' responses to SAVI learning. This study involved the experimental class and the control class taken from class VII (Seven) MTs Mishbahul Huda Kalimanggis District 2017/2018 Academic Year. The study used a descriptive test instrument to evaluate the students' mathematical representation skills and to use students' response questionnaires to find out students' responses to the applied learning. From the results of the pretest it was found that the mean score of the ability of the mathematical representation of the control class was 15.69 while the experimental class was 14.70. Through the t test on this value it is known that the value of t count = 1.41. While the degrees of freedom of 5% and dk = 44 are known to be t table = 2.732. From these two data we know that - 2.732 <1.41 <2.732 then fulfills H0 acceptance criteria which means that both classes have the same initial representation ability. Meanwhile from the post-test results it is known that the mean representation score of the control class is 26.91 and the average score of the mathematical representation of the experimental class is 33.33. From the results of the t test on this value obtained tcount = 3.21 and t table = 2.732. From the two data, it is known that -2,732 <3,21 <2,732, then tcount is not found in the reception area H0. This means that after treatment the ability of the experimental class mathematical representation is better than the control class. From the results of the z test the N-Gain score obtained zcount = -3 and ztable = 1.71. From the two data, it is known that -3 <1.71 then thitung is in the reception area H0. This means that after the treatment increases the mathematical representation ability of the experimental class is not in the high category. In addition, from the results of the student response questionnaire, it was found that students showed a positive response to the SAVI learning model.
