<![CDATA[Education through learning with heart is an effort to humanize humans. When human behavior today does not show like a caliph who maintains peace in life, such as having shortcuts which deemed appropriate, then the education and teaching system needs to be reformed. A learning model that forms an ability to think logically, critically, creatively, obediently or consistently and fosters self-confidence and character is student-centered learning which includes constructive, interactive and reflective stages.]]>

<![CDATA[This study aims to describe the mathematical understanding of junior high school students on quadrilateral based on the APOS theory. This study used a qualitative approach to the case study method with the subject as many as 3 students of class VII of one of the State Junior High Schools in Karawang district, using a test question description of comprehension and interview abilities. Data analysis in this study was carried out with data reduction, display data, and conclusion drawing or verification. Based on the results of data analysis, students with high abilities are able to meet the APOS stages on the indicators of presenting concepts in various forms of mathematical representations and developing necessary or sufficient requirements of a concept. Students with moderate abilities are able to meet the APOS stage on the indicators of presenting concepts in various forms of mathematical representations. And students with low abilities have not been able to meet the APOS stages on the four indicators. So, the students' mathematical understanding ability based on the APOS theory on the rectangular material is still low, where students have not been able to meet all the indicators of understanding based on the APOS theory.]]>

<![CDATA[This study aims to study the effectiveness of learning the subject of trigonometric comparison using media concept maps in class X Asy-Syafiiyah International Medan High School TP 2019/2020, to see how much changes in student learning outcomes taught with media concept maps in class X high school students Asy-Syafiiyah International Medan TP 2019/2020. The population in this study were all students of class X at Ash-Syafiiyah International Medan. The results of this study indicate that (1) the level of mastery of students there are 7 students or 18% the level of mastery is very high, 8 students or 21% the level of mastery is high, 18 students or 46% level of mastery is moderate, 5 students or 13% mastery level is low, 1 student or 2% mastery level is very low. This means that class X Asy-Syafiiyah International Medan students have mastered trigonometric comparisons with the application of concept map media. (2) Completeness of learning there are 33 students or 85% who have completed individually and 6 students or 15% who have not finished individually. This means that students have finished classically (3) Out of ten (10) TPKs are expected, achieved by students there are 10 or 100% TPK completed, (4) Observation results indicate that the implementation of learning is in the range of values 3 to 4 (5) The magnitude of the change in learning outcomes of students taught with media concept maps in class X Ash-Syafiiyah International Medan is 2.00, it can be concluded that the application of concept maps is effectively used in learning trigonometric comparisons.]]>

<![CDATA[The aim of this article is to analyze students’ mathematical logical thinking ability where accelerated learning model been applied. Research is conducted in fifth semester in one of universities in Asahan. It was found that the n-gain mean of mathematical logical thinking ability of class AL students was included in the high category improvement as stated by Hake's n-gain improvement criteria. The class AL standard deviation value shows that the distribution of the n-gain value data varies widely. This shows that the Accelerated learning (AL) learning model can be used as a model that can improve logical thinking skills.]]>
