Abstract

This research objective is to describe students’ thinking barriers and to describe given scaffolding to overcome students’ experienced thinking barriers. This is a descriptive qualitative research. Research subjects is 2 students whose thinking capability is high and low. Documents being studied are students’ test result, unstructured interviews transcripts, ands scaffolding. This research demonstrates that subject 1 (S1) barriers are caused by the lack of analogical thinking capability on understanding problem, the low connecting capability when implementing solving plan, and the lack of existing knowledge and connection capability on re-examine planned procedure on problem solving. Subject 2 (S2) thinking barriers are caused by the low analogical capability in understanding problem, the lack of connecting capability when planning problem solving strategy, the lack of analogical capability in planning problem solving, and the lack of prior knowledge and connection in re-examine chosen procedure. Adjusting Anghileri’s scaffolding, S1 was given scaffolding at a rate of explaining and developing conceptual thinking, while S2 was given scaffolding at a rate of explaining, reviewing, restructuring, and developing conceptual thinking.

Abstract

This study aims to describe the types of explanations made by pre-service teachers in mathematics learning. In this research, the types of explanations are used to describe the explanatory trends used by pre-service teachers in mathematics teaching. The descriptive qualitative research was chosen in this research. The research subjects are pre-service teacher as the students of Mathematics Education of PGRI Madiun University and Madura University who are studying Field Experience Practice. Of the 105 mathematics student, five students with a cumulative grade achievement of more than 3.50 were observed during the teaching practice at the school for approximately five meetings. The research data was obtained from observation, video recording, and interview. Data analysis was done through data condensation, data presentation, and conclusion/verification focused on pre-service teacher explanation on mathematics learning activity. The research findings indicate that the explanation used by the pre-service teacher in the mathematics learning starting from the most frequently used is the descriptive explanation (51,7%), giving of reason (36,2%) and interpretative (12,1%). Descriptive explanations are used to describe mathematical procedures. The type of reason-giving explanation is used to explain reasons based on mathematical principles. Furthermore, the interpretative explanation is used to explain the concepts and facts of mathematics.

Abstract

Learning mathematics in grade 1 using pieces of instructional media will generate motivation, stimulating learning activities, abstract concept and bring the psychological effects of a child. This study aims to generate media box material to know numbers and operations are valid, practical, effective and attractive. The model of development used modification 4D model developed by Thiagarajan. Validation results declared invalid by subject matter experts and very valid by media experts. Practicality and attractiveness of the product reaches 94 % categorized as very practical and very attractive. While the effectiveness of a product is marked with the positive response of students who achieve mastery of at least about 82 %

Abstract

Tujuan penelitian ini adalah mengembangkan bahan ajar berupa Lembar Kegiatan Siswa (LKS) bercirikan guided discovery dan berbantuan aplikasi grapher pada materi fungsi kuadrat untuk kelas X SMK yang valid, praktis dan efektif. Pengembangan bahan ajar bercirikan guided discovery dipilih karena berdasarkan hasil obsevasi peneliti, kegiatan pembelajaran perlu didukung dengan adanya bahan ajar sehingga siswa dapat aktif dalam pembelajaran. Sedangkan penggunaan aplikasi grapher diharapkan dapat membantu siswa menemukan konsep karakteristik grafik fungsi kuadrat dan mengarahkan hasil kecanggihan teknologi pada pembelajaran. Langkah pengembangan mengacu pada model pengembangan Plomp (2010:15). Langkah pertama, preliminary reseach, dilakukan peneliti dengan melakukan pengamatan kelas hingga diperoleh simpulan perlu adanya bahan ajar becirikan guided discovery dan berbantuan aplikasi grapher pada pembelajaran materi fungsi kuadrat. Langkah kedua, prototyping phase, dilakukan dengan merancang, membuat kemudian memvalidasi LKS, RPP dan instrumen penelitian. Langkah ketiga, assessment phase, dilakukan dengan menguji coba kepraktisan dan keefektifan bahan ajar pada pembelajaran. Berdasarkan hasil pengembangan diperoleh bahan ajar berupa LKS bercirikan guided discovery dan berbantuan aplikasi grapher pada materi fungsi kuadrat untuk kelas X SMK yang valid, memiliki nilai kepraktisan tinggi dan tingkat keefektifan yang baik
