Kemampuan literasi statistik merupakan kemampuan dalam melakukan interpretasi data dan informasi yang tersedia. Kemampuan tersebut merupakan salah satu kemampuan penting yang harus dimiliki oleh guru. Tujuan penelitian ini adalah untuk mendeskripsikan kemampuan literasi statistik mahasiswa calon guru Matematika yang dikaitkan dengan level berpikir taksonomi SOLO. Hasil analisis menunjukkan bahwa pencapaian kemampuan literasi statistic mahasiswa calon guru Matematika belum merata untuk setiap indikatornya, yaitu indikator penalaran terhadap data dan hasil statistika berada pada level multistruktural, indikator penalaran terhadap konsep dasar dan istilah statistika berada pada level unistruktural, indikator penalaran terhadap pengumpulan dan pengolahan data secara deskriptif berada pada level relasional, dan indikator melakukan interpretasi data berada pada level unistruktural.

The natural zeolite from Blitar deposits, a region of Indonesia were studied by simultaneous surface area and porosity measurement used BET analysis. XRD analysis was performed and the result was the natural zeolite contained mordenite and clinoptilolite and small quantities of quartz. From the pattern is also evident that the treatment doesn't affect the mineralogical structure, patterns are identical. Thermophysical analysis, morphology and Si/Al ratio were measured. The surface area increases significantly for natural zeolite after NaCl counterbalance treatment.

In order to cope with rapid changes in 21st century, preparation of pre-service teachers is viewed as crucial to the quality of teacher workforce. This article presents the findings of a study of Indonesian-Thailand pre-service teachers that participated in SEA- Teacher Project. This study used qualitative method to describe pre-service teachers’ perspective on pedagogical challenges as they participated in observations, assist in teaching, teach and reflect. Drawing from participant field notes, surveys and semi-structured interviews, by open-questions this study seeks to investigate the problems. During those phases, this study gathered the pre-service teachers’ field notes that indicates some challenging pedagogical experiences influenced their perspective in teaching mathematics. The findings reveal that language becomes their major challenge in delivering material (80%) that affected their perception in explains a topic, concept or procedure in mathematics. Some of them overcame this problem by developing learning media. Pre-service teachers are given the opportunity to do practice teaching, but some of them (30%) are given only 2-3 meetings, that causes pre-service teachers couldn’t develop variation of teaching strategies. Pre-service teachers did not have enough time to learn school’s curriculum and resulted in students having difficulties in developing lessons plan.They then try to keep the curriculum in their home country (40%) or used the lesson plan as an example in school (60%). Some obstacles experienced by pre-service teacher (20%) as they have to taught large classes (up to 50 students).They had to work hard in order deal with different characters of students so the class remain conductive. In deal with misconception when students make mistakes in working on a problem 90% of them only give the right answer, without exploring the possibility of a misconceptions. In practice only 30% of them identify the cognitive demands of students who are taught during the observation activity and assist of teaching. Limitations on school infrastructure such as LCD, computers, and internet inhibit the pre-service teacher to develop ICT based learning (50%) but they overcome the limitation by developing students’ worksheet and contextual mathematics model.

Indonesia spread between many ocean and contain of so many islands which has lots of volcanoes that produce natural resources for example natural zeolite. It usually used for water treatment, catalyst and fertilizer but less in cooling application. The alternative use of cooling system which used solar energy is adsorption. This research intend to characterize natural zeolite from one area in Indonesia depend on their thermal behavior and other characteristic that useful for an adsorbent. The result show that it could be a great adsorbent according to its characteristic such as indicate from surface area, comparison of Silica and Alumina and other characteristic result.

This research aims to describe the process of implementation Somatic, Auditory, Visualization, Intellectually (SAVI) learning approach to improve students’ attention toward mathematics lesson. The data were obtained from the result of questionnaire and observation. The success indicators in this research was the average of students’ attention reaching 70%. The results of this research showed that learning steps by using SAVI could improve students’ attention, the result as follows; 1) pre-activity: teacher delivered the purpose of the learning, apperception, and motivation. 2) main activity: the teacher explained learning materials, divided students into 4-5 persons to discuss the problem in a worksheet, the teacher guided students to solve the problem, gave chance to present the discussion result, then teacher held games that involve students’ sense tools as training for the learning materials. 3) post activity: the teacher together with students conclude the lesson and ask students to review the lesson at home. Based on the questionnaire result, the average of students’ attention in last cycle is 77,61%.
