Abstract

The purposes of this research were to study the concepts of the relations between two and three dimensional geometric figures and to study the ability to apply mathematical knowledge in the real life of Mathayom Suksa 1 students learned with mathematics learning activities connecting to the real life. The target group was 45 Mathayom Suksa 1 students at Maesaiprasitsart School in the second semester of academic year 2010. The instruments were lesson plans, a teacher record, a behavior observation form, journal writing, exercise checklist, posttest after learning, conception and ability to apply mathematical knowledge test. Data were analyzed by frequency, percentage and descriptive analysis. The study found that after learned with mathematics learning activities connecting to the real life, more than 80% of total students were able to pass the criteria of conceptions of relationships among two and three dimensional geometric figures in every concepts and more than 80% of total students were able to apply mathematical knowledge and pass the criteria in some application.
