Abstract. The objectives of this research were: 1) to describe the response level of mathematics students in Veteran Bangun Nusantara University Sukoharjo based on SOLO taxonomy in solving logic problems; 2) to describe the characteristic of students response at each level of SOLO taxonomy; 3) to study if there is misconception at each level of SOLO taxonomy about students response.This research was a qualitative research. The subject in this research were the students of Mathematics Education, Veteran Bangun Nusantara University on the first semester academic year 2014/2015. The main instruments used in this research to collect the data was the researcher and the other instruments were test instrument and interview guide instrument. Data analysis technique was conducted by data reduction, data presentation and data verification or made conclusion. The conclusions as follows. 1) Students response level based on SOLO taxonomy in solving logic problems comprised prestructural, unistructural, multistructural, relational, and extended abstract, 2) Students response characteristic at each level of SOLO taxonomy as follows. a) Prestructural: the answer completely irrelevant, could not understand the problem given, could not connect the concept and the answer, and the answer was illogical. b) Unistructural: there was a clear and simple relationship between one concept to another but the core of concept widely was not yet understood. c) Multistructural: understood some of the components but still separated from each other so a comprehensive understanding was not formed, some simple connections have been established however metacognitive abilities have not appeared yet at this level. d) Relational: could connect the fact and the theory and also connect the action and the objective, showed understanding ability of some components from the whole concept, understood the role of the parts to the whole and has been able to apply a concept in similar circumstances, have better ability to expressed ideas and made some automatic repetition. e) Extended Abstract: have the ability to think conceptually, to connect not only limited to the concepts that have been given alone but with concepts beyond that, could made generalizations in different problems and made parables in specific situations. 3) Based on the 5 response level of SOLO that happened to students, scheme on each level as shown below. At prestructural and unistructural response levels that were students who have misconceptions. At the multistructural response level, there were students who have a scheme but invalid because the result of the first and second data collection was not the same. The first result were correct scheme but the second result were misconceptions. At the relational response level, there were students who have misconceptions and at the extended abstract response level, there were students who have a correct scheme or in other words did not experience misconceptions.Keywords: SOLO taxonomy, response level, scheme, misconception.

Abstract: Problem solving ability was main objective in this mathematic’s learning. So this research intends to know the students’ achievement of mathematics which was better (1) students were taught by Problem Based Learning (PBL) with Writing Activities (WA), students were taught by Creative Problem Solving (CPS) or students were taught by Direct Learning, (2) students with high creativity, students with medium creativity, or srudents with low creativity, (3) in each category creativities, the students’ achievement of mathematics was better among the students were learnt by PBL with WA, CPS or direct learning models (4) in each model, the students’ achievement of mathematics was better among the students with high creativity, students with medium creativity, students with low creativity. This research used a quasi-experimental research with the population of tenth grade of High Schools in Tegal city in the Academic Year of 2014/2015. The sampling technique used stratified cluster random sampling and three schools were selected namely SMK N 1 Tegal, SMK N 2 Tegal, and SMK N 3 Tegal. Two-way variance’ analysis was used to test the hypothesis, followed by Scheffe’ technique.  The results of analysis  were as follows. (1) The students’ achievement by PBL with WA were better than by CPS and direct learning. The students’ achievement by CPS were better than by direct learning. (2) The students’ achievement with high creativities were better than with medium and low creativity. The students’ achievement with medium creativity were better than with low creativity. (3) In every category of creativities (high, medium and low), the students’ achievement by PBL with writing activities were better than CPS and direct learning. The students’ achievement by CPS were better than direct learning. (4) In every model of learnings (PBL with WA, CPS, and direct learning), the students’ achievement with high creativity were better than medium creativity and low creativity. The students’achievement with medium creativity were better than with low creativity.Keywords: Problem Based Learning with Writing Activities, Creative Problem Solving, Creativities, achievement of mathematics.

Abstract: This research intended to describe the mathematical representation of 7th grade students in SMPN 15 Surakarta in solving mathematical problem based on Krulik-Rudnick steps on the topic of social arithmetic and comparison viewed from cognitive style of Field Independent and Field Dependent. The procedure used to select the subject was snowball sampling, with six subjects consisted of three subjects in each cognitive style being analyzed. The data validation was carried out using time triangulation. The representation used by Field Independent (FI) students in solving mathematical problem based on Krulik-Rudnick steps was as follows: 1) In the first two steps, Read and Think and Explore and Plan, students used verbal representation; 2) In the next step, Select a Strategy and Find an Answer, students used symbolic representation; 3) In the last step, Reflect and Extend, students used visual and symbolic representation. The representation used by Field Dependent (FD) students in solving mathematical problems based on Krulik- Rudnick steps was as follows: 1) In the first two steps, Read and Think and Explore and Plan, students presented the given information and asked questions by using verbal and visual representation gradually, clearly and correctly; 2) In the next step, Select a Strategy and Find an Answer, students used symbolic representation by assuming the given information and asked questions into “x” and “y” and wrote it in incorrect algebraic equation, wrote simple interest rate and proportion formula, as well as used symbolic representation by substituting one equation to another incompletely, yet had a correct final result; 3) In the last step, Reflect and Extend, students used verbal and visual representation.Keywords: mathematical representation, problem solving, cognitive styles

Abstract: This research was aimed to decribe metacognition activity of male and female students in mathematics problem solving. This research was a qualitative research which used case study method. The subject of the research was 7th students of SMP Negeri 1 Nanggulan. The subject selection criteria was based on students opinion expressing competency either in spoken and written form. The data was collected using think aloud method where the students were asked to express their ideas and questions loudly in mathematical problem solving processes. Then the time triangulation was run to produce a valid data from the research subject. The data analysis was conducted using Miles and Huberman model. The result of research showed : 1) the metacognition activity of the male students are : a) understanding the problems phase : perform activities related to strategic knowledge; b) devising a plan phase : perform activities associated with knowledge about cognitive tasks; c) carrying out the plan phase : perform activities related to strategic knowledge and associated with knowledge about cognitive tasks; d) looking back phase : perform activities related to knowledge strategy and perform activities associated with self-knowledge. 2) the metacognition activity of the female students are : a) understanding the problems phase: perform activities related to strategic knowledge and perform activity associated with self-knowledge; b) devising a plan phase : perform activity associated with knowledge about cognitive tasks; c) carrying out the plan phase : perform activity related to strategic knowledge and associated with knowledge about cognitive tasks; d) looking back phase: perform activities related to strategic knowledge and  perform activity associated with self-knowledgeKeywords: metacognition, mathematics problem solving, gender
