Publisher : Department of Doctoral Program on Mathematics Education, Sriwijaya University

Information literacy is mostly seen from the perspective of library science or information and communication technology. Taking another point of view, this study was aimed to explore students' information literacy from the perspective of mathematical literacy. For this purpose, a test addressing Programme for International Student Assessment (PISA) mathematics tasks were administered to 381 eighth and ninth graders from nine junior high schools in the Province of Yogyakarta. PISA mathematics tasks which were used in this test had specific characteristics regarding information processing, i.e. containing superfluous information, having missing information, and requiring connection across information sources. An error analysis was performed to analyze studentsâ€™ incorrect responses. The result of this study shows that students did not acquire three characteristics of information literacy; i.e. recognizing information needs, locating and evaluating the quality of information, and making effective and ethical use of information. This result indicates students' low ability in information literacy.Keywords: information literacy, mathematical literacy, Programme for International Student Assessment (PISA)

Mathematical thinking is an important aspect of mathematics education and, therefore, also needs to be understood by prospective teachers. Prospective teachers should have the ability to analyze and interpret students’ mathematical thinking. Comparing model is one of the interpretation models from Wilson, Lee, and Hollebrands. This article will describe the prospective teacher used the model of the building process in interpretation students' mathematical thinking. Subjects selected by considering them in following the students’ strategies in solving the Building Construction Problem. Comparing model is a model of interpretation in which a person interprets student thinking based on student work. There are two types comparing model building process prospective teacher use in interpreting students’ mathematical thinking ie. comparing work and comparing knowledge. In comparing works, prospective teachers use an external representation rubric. This is used to analyze student activities in order to provide an interpretation that is comparing the work of students with their own work. In comparing knowledge, prospective teachers use internal representation rubrics to provide interpretation by comparing the students' work with their knowledge or thought.

This paper sketches the approach of design-based research in mathematics education with results oftwo innovation-oriented projects. The projects investigated how students can be involved in thedevelopment of mathematical concepts and skills by using design tools related to guided reinventionand emergent modelling. Both studies combine design-based research with a prominent role for thehypothetical learning trajectory as a research instrument in the three phases of design research (design,teaching experiment, retrospective analysis). Each of the phases of the research cycles is addressed: thepreliminary phase in which a hypothetical learning trajectory and instructional activities are designed,the teaching experiment phase and the phase of the retrospective analysis. We conclude with areflection on design-based research as an approach to study innovative teaching approaches that offersresearchers to take into account contextual factors and that create opportunities for others to adapt theresults to their research or teaching practice.

Tujuan penelitian ini adalah untuk mendeskripsikan learning trajectory berbasis proyek yang dilalui siswa untuk memahami definisi himpunan. Penelitian desain ini menggunakan model Gravemeijer dan Cobb dengan tahapan yang terdiri atas: (1) preparing for the experiment yang mencakup penyusunan hypothetical learning trajectory (HLT); (2) design experiment yang mencakup pelaksanaan pembelajaran berdasarkan HLT yang telah dirancang; dan (3) retrospective analysis, yaitu membandingkan HLT dengan pembelajaran yang dilaksanakan. Pengembangan HLT menjadi learning trajectory diperoleh melalui serangkaian aktivitas yang dilaksanakan dengan pengumpulan data melalui dokumentasi, observasi, dan wawancara dengan guru dan siswa untuk mengklarifikasi dan mengonfirmasi alur belajar. Hasil penelitian mengindikasikan bahwa pembelajaran berbasis proyek dapat memfasilitasi siswa dalam memahami definisi himpunan. Learning trajectory definisi himpunan berbasis proyek diperoleh melalui serangkaian aktivitas dengan empat level pemodelan. Level situasional berupa aktivitas survei kumpulan objek di sekolah. Pada level referensial, istilah “ciri-ciri yang sama”, “dapat didefinisikan”, dan “objek tambahan”, dan “kesepakatan” muncul melalui diskusi. Pada level generalisasi, siswa menuliskan himpunan dalam bentuk yang lebih umum. Terakhir, pada level formal, pemahaman yang siswa peroleh dari setiap aktivitas merupakan modal untuk membangun konsep tentang definisi himpunan.Project-based learning trajectory on the definition of the set topicAbstractThis research aimed to describe the project-based learning trajectory passed through by students to understand the set definition. This design research used Gravemeijer and Cobb model with stages: (1) preparing for the experiment that includes developing hypothetical learning trajectory (HLT); (2) design of experiments which includes learning practices implementation based on the developed HLT; and (3) retrospective analysis, which was to compare HLT with learning practices. The development of HLT into a learning trajectory was obtained through a series of activities carried out by collecting data through documentation, observation, and interviews with the teacher and students to clarify and confirm the learning trajectory. The results indicated that project-based learning could facilitate students to understand the definition of set. The learning trajectory was obtained through a series of activities with four levels of modeling. The situational level was in the form of a survey activity aimed to collect objects in the school area. At the referential level, the terms “common features”, “definable”, “additional objects”, and “agreement” emerged through discussion. At the generalization level, students wrote the set in a more general form. Lastly, at the formal level, the understanding that students get from each activity was a provision to construct a concept about set definition.
