Abstract

Previous studies suggested that real-world problems and students’ characteristics should be emphasized when designing statistics teaching materials. ELPSA Framework could address those considerations and was used as a learning framework for teaching statistics to junior high school students. Prior to classroom implementation, the teaching materials was tested and deemed valid and practical. Pilot implementation results showed that the teaching materials was effective for learning statistics because the ELPSA framework components facilitate students’ understanding of statistical concepts. Students also perceived learning based on the ELPSA framework positively because it enables them to enjoy the learning process.

Abstract

Teaching and learning mathematics should provide opportunity to student to express, explain, and give reason regarding what they are thinking. In addition, teaching and learning mathematics should make student active, creative, efective, meaningful, and joyful. Students are able to think accurately and communicate properly. These are relevant to the essence of teaching and learning mathematics, mathematical thinking and mathematical communication. By teaching and learning matematics student is supported to catch the idea of concepts, rules, and principles of mathematics, and then revoicing all of them. Even they should be able to defence what they assume as rightness argumentatively (mathematical argumentation or mathematical reasoning). Even though mathematical argumentation is one of important mathematical competences, but it has to make student to proportionaly master. However, mathematical argumentation is mathematical creativity with in tolerances to get the real meaning of learning mathematics. Teaching and learning mathematics can use to (i) highlight ideas that have come directly from students; (ii) help develop students’ understanding that are implicit in those ideas; (iii) negotiate meaning with students, and (iv) add new ideas, or move discussion in another direction.

Abstract

Plastic membrane sensor for polarographic oxygen measurement has been investigated. The Probe was constructed of: Pt as a working electrode; Ag-AgCl as a reference electrode and an auxiliary electrode; solution of KCl as an electrolyte solution; plastic wrap (thickness 72.7 mm) as a membrane; and polyester polymer as a body of sensor. It was found that the polarographic oxygen sensor plastic membrane probe was suited for determination of dissolved oxygen with an optimum operating characteristics at applied voltage of  –0.65 V and solution KCl 30% as an electrolyte. The probe showed that reduction current achieved steady state after 75 seconds. The standard calibration curve (concentration – current) showed that the linear relationships were achieved for dissolved oxygen in the range of 1.0 – 30.6 ppm.The analytical performance characteristics of the probe were: precision 0.87% – 30.0 %; calibration sensitivity 0.17 ppm/mA; analytical sensitivity 0.56 – 0.84 ppm/mA; and detection limit 0.8 ppm. The t- test and F-test at 95% confidence level showed that there was no significant difference between the determinations of dissolved oxygen by polarographic oxygen sensor membrane plastic and by Winkler method.

Abstract

The purpose of this study was to examine the forms of representation constructed by primary school students in solving mathematical problems. Representation is the basis or foundation of how a student could understand and use mathematical ideas. The forms of representation, such as charts, graphs, and symbols, are essentially a long process of learning mathematics, but unfortunately these representations are often thought of and studied in its final form. Actually, representations should be given as support in the process of understanding concepts, the associations of mathematics, mathematical communication, constructing arguments, and apply mathematical concepts in everyday life through modeling. This research showed that the forms of representation constructed by the students are extremely varied. They are constructed in tables, images, patterns, and in the formal forms of mathematics (the formula). This study was also revealed that some students are able to develop forms of representation using logical mathematical processes. Students begin to formulate a representation using known premise, set the table, make conjecture, and subsequently arrange a formal representation.
