The effectiveness of an autograph-assisted problem based learning model for improving high school students' learning outcome on graphics functions

Abstract

Students' learning outcomes can be enhanced through tasks that require students to relate images in their daily life to mathematical graphs. However, students find it difficult when they draw mathematical graphs by using pens or pencils. Therefore, they need a digital tool to assist them. This study aimed at developing a digital tool for teaching and learning of graphics functions. It adopted Plomp's model of design research that consists of three phases: (1) preliminary research (2) prototyping phase, and (3) assessment phase. It is important to highlight that this paper presents the assessment phase of the study. Data were collected to determine the effectiveness of Autograph-assisted problem-based learning model. Participants of this study were 17 year-ten students from a high school in Banda Aceh city, Indonesia. Data were obtained through student's worksheet and questionnaire, and it was analysed descriptively. The findings showed that 88% of the students achieve learning objectives and 90% of them had positive responses toward the leaning.
