A Construction Test of Scientific Literacy in the Earth Science and Space of Bachelor’s Degree Students, in the Science Teaching Program on PISA's Scientific Literacy Assessment Framework

Abstract

The purposes of the research were to create the test of scientific literacy in the earth science and space of bachelor’s degree students in the science teaching program on PISA's scientific literacy assessment framework. There were 2 target groups; firstly, key contributors for developing the test which specific selection, three science teaching specialist or earth and space science specialist and two curriculum or educational evaluation experts, secondly, the test. The participants were 30 bachelor’s degree students of the science teaching program in Ramkhamhaeng University. The research tools were 1) the assessment form of the conformity and appropriateness of the test of scientific literacy in the earth science and space, 2) the test of scientific literacy in the earth science. The statistics of this research were mean, index of difficulty, Index of discrimination and reliability uses KR-20 formula.

          The result of the research was the test of scientific literacy in the earth science and space of bachelor’s degree students in the science teaching program on PISA's scientific literacy assessment framework about four multiple-choice of 30 items which evaluates three parts of competency. There were 12 items for explaining scientific phenomena, 9 items for evaluating and designing scientific Inquiry, and 9 items for interpreting the data and scientific evidence. The index of item objective congruence (IOC) in each item was between 0.60-1.00, the Index of difficulty of every item was 0.27-0.73 except item 4 and item 20 was too difficult (the index of difficulty of two items 0.17). Therefore, the researcher improves the quality of items. The index of discrimination of every item was 0.22-0.78 and the calculation of internal consistency of reliability by KR-20 was 0.65.
