In this study, we analyzed energy and climate change concepts in elementaryand middle school science textbooks. A conceptual map drawn up by specialistswas chosen as the criteria for locating relevant concepts in textbooks. It wascomposed of 52 main concepts and some supplementary concepts divided byexperts into elementary and middle school learning levels. We recorded gradelevels, chapters, and paragraphs containing relevant concepts in textbooks. Therecorded concepts were then examined to determine whether they conformedto the correct levels. Three textbook versions, including the Kang Hsuan, Nan-I,and Han Ling versions, were analyzed.At the elementary school level, findings showed that the Kang Hsuan versionneeds to increase content on climate change more than the other versions. Atthe middle school level, all three versions were similarly deficient of content, butthe number of concepts was lower than that suggested by experts. We also analyzedcontinuity and sequence of five subject concepts presented in differentversions. The Nan-I version presented better on the subject of energy. None ofthe three versions met the criteria on the impact of climate change. Han Ling presented better on the rest of three subject concepts. |
