This study was a pre test-post test experimental control group design having a goal to analyze  the role of prior mathematics ability (PMA) and Problem Solving Approach (PSA) on student’s mathematical critical  thinking ability (MCTA)  and disposition (MCTD). The study involved 65  eleventh grade students, a prior mathematics ability (PMA), a MCTA test, a  MCTD scale. The study found that PMA and PSA took roles on obtaining student’s MCTA and MCTD, those were the higher student’s PMA the study found the higher students MCTA and MCTD. Beside that, on MCTA and its N Gain, entirely and with low and medium PMA students  getting treatment with PSA attained  better grades than the grades of students taught by conventional teaching (CT);  and for entirely and with medium and high PMA, student recieving treatment with PSA obtained higher grades on MCTA and MCTD than student  taught by CT and those grades were at good grade level. The other findings, there was no association between MCTA and MCTD, and no interaction between PAM and teaching approaches toward MCTA and on MCTD and student  learn  actively during PSA

The purpose of this study was to describe the role of scientific approach on students’ mathematical critical thinking and resiliency. This study wass a pre test-post test experimental control group design and involves 66 seventh grade students as sample. Data collection was conducted by a mathematical critical thinking test, a mathematical resiliency questionnaire, and a perception on scientific approach questionnaire. Data analysis was conducted using descriptive and inferential analysis. The study found that on mathematical critical thinking ability, students getting treatment by scientific approach attained better than students taught by conventional teaching, but both groups were still at low level.  On mathematical resiliency,  there was no different between students on both teaching approaches, and those groups were at medium level.  The other findings, there was no association between mathematical critical  thinking  ability and mathematical resiliency, and students performed high perception toward scientific approach.

The purpose of this study is to analyze  the role of mathematics realistic education (RME)  approach on students’ mathematical critical  thinking  and resiliency. This study is an experiment with pre test-post test control group design and involves 62  eleventh grade students, a mathematical critical  thinking test, a mathematical  resiliency scale, and a perception on RME approach scale. The study found, on mathematical critical   thinking  ability (MCTA), its N Gain, and  mathematical resiliency (MR) students getting treatment with RME approach attained better grades than the grades  of students taught by conventional teaching. The first group students attained at medium grade level on MCTA and fairly good grade level on MR, while the second group students  obtained  at low grade level on MCTA, medium grade level on MR, and they realized difficulties in some  items of  mathematical critical  thinking tasks. The other findings, there was no association between MCTA and MR, and students learned actively, thought critically and creatively, were unafraid to pose their opinion and performed to be  self confident during  RME approach.

The purpose of this research is to know the influence of biology teaching through inquiry integrated with cooperative towards the critical thinking ability. This research addresses the role of inquiry and cooperative learning strategy as well as these interactions towards the increase of the critical thinking ability. Quasi experimental research of Pretest-postest nonequivalent control group design with factorial design 2x2x2 were implemented on the odd semester in academic years of 2006/2007  on X grade student of the state SMA in Metro City Lampung. The  research sample consists of 96 students, comprising of student from high and low academic abilities. To examine hypothesis, it is used Ancova technique and continued by LSD test. There was a difference on the critical thinking ability  between students who learn by inquiry level 1 with student who learn by inquiry level 2, between students, who have high academic ability and students who have low academic ability, and there was not difference on the critical thinking ability  between students who learn by STAD cooperative  with student who learn by TPS. There is no effect of interaction between inquiry with cooperative, inquiry with student’s academic ability, cooperative with student’s academic ability, inquiry with cooperative and student’s academic ability towards the cognitive achievement Kata kunci: cooperative learning, inquiry, berpikir kritis

The aims of this study are to determine the improvement of critical thinking skills mathematical and metacognition of students who are taught with problem solving approach and the correlation between mathematical critical thinking and metacognition of students. This research is an experimental research with pretest-posttest control group design. The sample this research is the students of class VIII_2 and VIII_3 in SMP Negeri 1 Banda Aceh. Collecting data technique are test and nontest. Data were analyzed using t-test and correlation test. The result of the research shows 1) the critical thinking ability of the students who get the learning through problem solving approach is better than the students who get the conventional learning, 2) Metacognition of students who get the learning by using problem solving approach is better than the students who get the conventional learning, 3) a positive and significant relationship between students' metacognition and critical thinking skills.

Test Result

This study was aimed to find out the effectiveness of cooperative script learning model with handout towards the students’ critical thinking ability. The design of the study was quasi experiment in the form of nonequivalent pretest-posttest control group design. This study was conducted in SMA N 1 Gubug on 1st -22th August 2015 with the population of an entire class of X classes in SMA N 1 Gubug. The sample of the study consisted of two classes taken with cluster random sampling technique that was class X-F as experimental class and the class X-G as the control class. The data collecting technique were test and documentation.Based on the data analysis, it was obtained the means of the pretest score of experimental class was 44,77 and the control class was 33,33. Meanwhile, the students’ average score of post-test in experimental class was 80,40 and the control class was 73,70. Based on the pre-test and post-test result from those classes, it showed that there was a significant effect between students’ independence and students’ outcome in experimental class compared with control class. The hypothesis testing used significant level 5% was obtained tcount = 2,83 dan ttable = 1,67. This result indicated that cooperative script learning model with handout is more effective to improve students’ critical thinking ability

This study was a pre test-post test experiment without control group design having a goal to examine the role of Prior Mathematics Ability (PMA), Sylver  approach (SA) toward student’s mathematical creative thinking ability (MCTA) and Self Regulated Learning (SRL).  The study involved  65 eleven  grade student, a PMA test, a MCTA test, and SRL scale. The study found that PMA and SA took good role on obtaining student’s MCTA, its N<Gain> and SRL. On student’s MCTA, and its N<Gain> students getting treatment with SA attained better grades than that of students taught by conventional teaching, and the  grades were still at medium level.  On SRL,  there was no different grades between students on both teaching approaches, and those grades were at fairly good  level.  The other findings, there was no association between MCTA and SRL, and students performed high perception toward SA.
