Lift the flap story book based on child-friendly: Improving the ability of students mathematical connection

Abstract

This study aimed to: 1) produce a lift the flap story book based on child-friendly which is feasible to improve the ability of students' mathematical connection; and 2) reveal the effectiveness of the media in improving the ability of students' mathematical connection. This study is research and development. The preliminary data is collected through observation, questionnaire, and interview techniques to 173 students of fourth grade. The results of a preliminary study are used to basic of media development. Furthermore, data collected by scales and tests. The data analysis used descriptive analysis, normality dan homogeneity data and t-test. The results showed that: 1) the media has passed the criteria of feasibility based on expert validation result, the responses scale of teachers and student (very good); 2) the media has developed is effective to improve the ability of students mathematical connection based on t-test result where sig.2 tailed value <0,05. The result of t-test for control class and experimental class I is indicated by sig.2 tailed 0,008 <0,05 while control class and experimental class II is indicated by sig.2 tailed 0,002 <0,05. Through media has been developed, students can improve the ability of mathematical connections and internalize the moral message about child-friendly.
