The Development of Integrated Learning Unit on the Statistics and Data Analytics to Enhance Mathematical Connection Abilities for Twelfth Grade Students

Abstract

The purposes of this research were: (1) to develop an integrated learning unit on Statistics and Data Analysis, and (2) to compare students’ mathematical connection abilities before and after         receiving instruction through the integrated learning unit. The integration was designed in the form of an interdisciplinary approach, in which learning contents from related subject areas were connected, with mathematics serving as the core subject of the integration. The sample consisted of 27 Grade 12 students from one classroom at Ongkharak Demonstration School Srinakharinwirot University, Nakhon Nayok. The participants were selected through simple random sampling from five classrooms offering this course, using the classroom as the sampling unit. The research instruments were the integrated learning unit on Statistics and Data Analysis and a mathematical connection ability test with a reliability coefficient of 0.51. The statistical methods used for data analysis included mean, standard deviation, and hypothesis testing using the Wilcoxon signed-rank test.
 
The research findings revealed that:

 
1) the integrated learning unit on Statistics and Data Analysis had an efficiency of 86.33/83.46, and
 
2) the students’ mathematical connection abilities after the instruction were  significantly higher than before the instruction at the .05 level.
