Abstract

We examine how rectangular array model can support students' spatial structuring in learning multiplication. To begin, we define what we mean by spatial structuring as the mental operation of constructing an organization or form for an object or set of objects. For that reason, the eggs problem was chosen as the starting point in which the students could recognize such an arrangement. Geoboard was also be used as a tool to visualize the array. This research focused on a design research that was conducted in Surya Institute Program (SIP) in which investigated 12 Papuan students (between 10 and 11 years old) in connecting rectangular array model with the idea of multiplication. The result showed that rectangular array model indeed support the students to count things more efficient, able to see the structural similarities of arrays and created spatial structures for sets of objects.

Abstract

Based on TIMSS 2011 and PISA 2018, mathematical connection ability of Indonesian students has not been optimal. Some of questions in TIMSS and PISA measured the mathematical connections ability. Needed the instructional media to increase mathematical connection ability, such as puzzle and GeoGebra. In addition, gender also affects students' mathematical ability. This study aims to investigate differences in mathematical connection abilities between students who learning by puzzle and GeoGebra, investigate differences in mathematical connection abilities between male and female students, and investigate interactions between instructional media and gender. This research was a quasi-experiment which used nonequivalent control group design. The samples were students of class VIII-A and VIII-B in Junior High School of 1 Tangerang City. The instruments in this research consisted of test items, such as pretest and posttest. Hypotheses test through parametric test (ANOVA Two Tail). Based on ANOVA Two Tail-test result, showed that there is difference increase in mathematical connection ability students who learning by GeoGebra and puzzle. Then, there is no difference increase mathematical connections ability between male and female students. The factors of instructional media and gender do not equally affect the increase of mathematical connection ability.
