Abstract: This reaserch aimed to reveal the effect of a Problem Solving and a Problem Posing learning model assisting by media instrument to the mathematics achievement based on the students’ learning creativity. We used the second grade students of Junior High Schools in Pontianak as the population. This was a 3 x 3 factorial design quasi-experimental research. The techniques of data collection were a test, questionnaires and documentation method. The balance test, a prerequisite tests analysis (normality and homogeneity test), and hypothesis test using unbalanced two ways analysis of variance were the techniques of data analysis that used in this research. The result indicates: (1) a Problem Solving learning model assisting by media instrument gives the same mathematics achievement as a Problem Posing learning model assisting by media instrument, but it gives better mathematics achievement than a directed learning; Furthermore, there is no difference of mathematics achievement between a Problem Posing learning model assisting by media instrument and a directed learning; (2) the students with high, medium an low learning creativity have the same mathematics achievment; (3) for all category of the learning creativity, a Problem Solving learning model assisting by media instrument gives the same mathematics achievement as a Problem Posing learning model assisting by media instrument, but it gives better mathematics achievement than a directed learning; Furthermore, there is no difference of mathematics achievement between a Problem Posing learning model assisting by media instrument and a directed learning; (4) for all category of the learning models, the students with high, medium an low learning creativity have the same mathematics achievment.Key words : Problem Solving assisting by media instrument, Problem Posing assisting by media instrument, directed learning, learning creativity, mathematics achievement

Abstract: This research aims to describe how the reasoning characteristics of the 11th students of Senior High School about samples. This study was a descriptive qualitative research. The subject of research was the 11th students of SMA Negeri 1 Purwodadi consisting of two students for each level of mathematics competency. The subject selection criteria were based on student mathematics competency and opinion expressing competency, either in spoken and written form. The data was collected using written test and interview technique. The data analysis was done based on the data on written test and interview results. Then the method triangulation was run to produce a valid data from the research subject. The result of research showed that the students with low mathematics competency were at level 1 with the following characteristics: the students can give example of sample, can describe term of sample, approve the small number of sample selection in the research, do not recommend appropriate selection in sample taking. The students with medium mathematics competency were at level 2 with the following characteristics: the students can give example about the sample, can describe term of sample, combine small size with appropriate selection methods or large sample size with inappropriate selection methods. Some students with high mathematics competency were at level 2 and some other were at level 3 with the following characteristics: the students can give example about sample, can describe term of sample, recommend of the larger size sampling from the population, recommend the selection through random sampling technique and can explain the procedures randomly, and can identify the potentially biased sampling in a research.Keywords: Reasoning, Reasoning about Sample, Sample Concept, Reasoning Characteristics about Sample.

Abstract: The objective of this research is to investigate the profile of response in solving SOLO taxonomy-based algebra problems of the students in Grade VIII with the high, medium, and low Mathematics learning interests. Structure of Observed Learning Outcome (SOLO) taxonomy is a framework to classify the students’ response comprising 4 levels. The subjects of the research consisted of six students in Grade VIII of MTA junior Secondary School of Gemolong, Sragen in academic year 2011/2012.The instrumen used were test instrument, and the interview guideline.the data analysis so as to find out the response in solving SOLO taxonomy-based algebra problems.The results of the research are as follows. The response levels in solving SOLO taxonomy-based algebra problems of two subjects with the high Mathematics learning interest belong to extended abstract level (level 4).The response levels of two subjects with the medium Mathematics learning interest in solving SOLO taxonomy-based algebra problems are different from one to the other; one of them has the relational level (level 3) while the other has the multi-structural level (level 2). For this case, the students with the same Mathematics learning interest category (medium level) have the have different response.The response levels of two subjects with the low Mathematics learning interest in solving SOLO taxonomy-based algebra problems are also different from one to the other; one of them has the multi-structural level (level 2) while the other has uni-structural level (level 1). For this case, the students with the same Mathematics learning interest category (low level) have the different response.Key words: Students’ response level, algebra problems, SOLO taxonomy, and Mathematics learning interest

Abstract: This research aims to find out: (1) which learning model providing better learning achievement, PBI, Guided Inquiry or Conventional learning, (2) which students having better learning achievement, those with high, medium or low creativity, and (3) in each creativity level, which one providing better learning achievement, PBI, Guided Inquiry or Conventional learning model. In each learning model which students having better learning achievement, those with high, medium or low creativity. The population of research was all students of Junior High Schools throughout Blora Regency. The sample was taken using stratified cluster random sampling. The sample of research consisted of 272 students: 92 in the first experiment class, 91 in the second experiment class, and 89 in the third experiment class. The result of research showed that: (1) PBI model provided better learning achievement than the guided inquiry model did, but provided learning achievement equally good to the Conventional learning model did and Conventional learning model provided better learning achievement than the guided inquiry model did; (2) the students with high creativity had learning achievement better than those with both medium and low creativity had, and the students with medium creativity had learning achievement equally good to those with low creativity had. (3) In PBI and guided inquiry learning models, the students with high creativity had learning achievement better than those with low creativity had, the students with high creativity had learning achievement equally good to those with medium creativity had, and the students with medium creativity had learning achievement equally good to those with low creativity had. In conventional learning, the students with high creativity had learning achievement equally good to those with both medium and low creativity. At high and medium creativity level, PBI, Guided Inquiry and Conventional Model provided the equally good learning achievement. Meanwhile, at low creativity level, PBI learning model provided learning achievement equally good to the conventional learning model did, and Conventional learning model provided learning achievement better than the Guided Inquiry learning model did.Keywords: PBI, Guided Inquiry, Conventional, Creativity
