<![CDATA[The aim of this research is: 1) identifying the condition of teaching and learning in the classroom applying ECGV learning model; 2) comparing the improvement of higher order thinking skill when ECGV learning model is applied and without the ECGV learning model; 3) examining the efforts to improve the influencing factors of students’ higher order thinking skills. This study applies quantitative approach with a rationalistic paradigm. At first, this study described the condition of the controlling class, in which students were learning as usual, as well as experimental class carried out applying the ECGV model (Exploration, Conjecture, Generalization, and Verification). Different treatments were applied to the controlling and experimental classes to have the difference in normalized gain values to indicate an improvement of the achievement in this learning stage. The research results indicates that: 1) ECGV model is an effective learning model to improve skills within the learning process as well as students' thinking skills; 2) The ECGV stages should be applied from stages 1 to 4 accordingly, considering some factors that should be the focus for improvement; 3) Learning result indicated by in students' thinking abilities in the lower class increases greater than the higher class; 4) Some determining factors in the improvement of students' reasoning skills are found; class climate (environment, teacher and school), student psychology, and student intellectuals.]]>

<![CDATA[This research aims to describe the skill of mathematics model lecturer and the learning achievement of undergraduate students in lesson study practice. Lesson study activities consist of three phases, namely, planning (plan), teaching and learning practice (do), and observation and reflection (see). Reflection is a crucial phase in Lesson Study activity, since it determines the next step needed for improvement. Reflection activities require teaching skills of the model lecturers. The data was collected in line with the ongoing activities in the Field Work Practices involving 3 mathematics model lecturers and 36 undergraduate students, academic year of 2017 offering C Mathematics Education, Universitas Negeri Malang (Malang State University). The research result shows that (1) The model lecturer teaching skills develops along with lesson study practice; (2) lesson study practice supports model lecturers in developing teaching and learning, as well as improving students' learning achivements.]]>

<![CDATA[This study aims to see the differences in students' self confidence between students with the treatment of the creative problem solving learning model and the discovery learning model analysed based on gender. The data analysis was done using two-way Anava with different number of cell to see the effect of gender and learning models on students' self confidence. After the effect of gender and the learning model was found, a further post-Anova test using Scheffe method was executed. This analysis shows the following results: gender has an influence on students' self confidence as well as there is an influence of the learning model on students' self confidence, there is no interaction between gender and learning models on students' self confidence. When a post-Anova test with Scheffe's method was applied, it is found that there are differences in students' self confidence between the creative problem solving model and the discovery learning model. Female students have better self confidence than male students , while the creative problem solving model provides better self confidence than discovery learning model.]]>

<![CDATA[Learning mathematics aims to make students able to solve problems they will face in the future. This can be hampered if students have difficulty in learning. Difficulties experienced by students in solving system of linear equations material, namely difficulties to carry out procedures in determining the completion. In learning, the teacher has not used teaching aids to overcome student difficulties. Teaching aids can be an alternative solution to determine the completion of system of linear equations. This study aims to produce teaching aids that can help students to determine the solution. The type of research applied was a 4D model development research. To produce good teaching aids, valid tests, practical tests and effective tests were carried out. In this study, the produced teaching aid is called “Catur SPLDV”. The validity test result of the teaching aid was 3.59 with very valid criteria. The practicaliy test result of Catur SPLDV was 86.67%; very practical criteria. While the effective test result is 0.73 with high criteria analyzed using the normalized-gain (n-gain) test. Catur SPLDV is used to help students to determine the solution of linear equations system of two-variable using the concept of Cartesian coordinates and number patterns. It can be used while playing a game, and containing a little algebraic elements making it easier for students to determine the solution of system of linear equations with two-variable.]]>

<![CDATA[This study aimsto analyze the effect of PBL and direct learning model towards improvement of mathematical connection ability, anlysed based on the initial mathematics ability of senior high school students at North Bekasi. This is a quasi experiment research. The treatment of PBL model was applied to the experiment class, while the controling class applied a direct learning model. The population of this study was the students of SMA Negeri 4 Kota Bekasi grade XI IPA academic year 2016/2017 whic was a normal population consisting of homogenous students. The instruments used consisted of mathematical connection ability test, initial mathematical ability test. Prior to the aplication, the instrument has passed the test of content validity, construct validity, and empirical validity. Data analysis was done using two-way Anava test and t-test. Based on the research results, it is found that: (1) improvement of student’s mathematical connection ability given PBL model treatment is higher than those direct instruction models was applied. (2) there is an interaction between the learning model and the initial mathematical ability to improve students' mathematical connection ability. (3) the improvement of mathematical connection ability of students with high mathematics initial ability to whom PBL model was applied is higher compared to students who got direct learning model treatment.]]>

<![CDATA[The ability to think creatively is an important ability in mathematics to deal with the demands of the 21st century. One learning model that can improve students' mathematical creative thinking skills is Project Based Learning. This study aims to determine the improvement of students' mathematical creative thinking abilities through Project Based Learning using Transformation Gymnastics and Tetris GeoGebra. Research instruments used in this study is a test in the form of description, consisting of pretest and posttest that measures the ability of mathematical creative thinking including fluency, flexibility, originality, and elaboration. Data analysis includes tests of normality, homogeneity, and t-test using SPSS application assistance. The results showed that there was a significant increase in the value of students' creative thinking abilities, both in classrooms with Project Based Learning using Transformation Gymnastics and in classrooms with Project Based Learning using Tetris GeoGebra. There was no significant difference between the average posttest in the two classes. Thus, the two project tasks used in this Project Based Learning can be used in learning Transformation material.]]>

<![CDATA[One of the thinking skills can be developed through mathematics education is critical thinking. Teacher may take one of the steps to stimulate critical thinking skills by means of CCT (Cards of Critical Thinking) learning media. CCT is a learning media in the form of question cards; containing critical thinking questions like "is there something wrong, why it is wrong, and what should be done to correct the mistakes". The questions in this CCT met the criteria and indicators of critical thinking, namely FRISCO (Focus, Reason, Inference, Situation, Clarity, and Overview). The CCT is applied through the PBL (Problem Based Learning) approach. The main purpose of this literacy study is to describe teaching and learning steps through the application of CCT (Cards of Critical Thinking) to improve students' critical thinking skills.]]>
