 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Thai High School Students’ Understanding of Heat
and Thermodynamics) ผู้เขียน: ดร.ทัศตริน วรรณเกตุศิริ, รองศาสตราจารย์ , ดร.สุนันท์ สังข์อ่อง, รองศาสตราจารย์ , นางเพ็ญจันทร์ ซิงห์, รองศาสตราจารย์,  Alister Jones สื่อสิ่งพิมพ์:pdf AbstractThis research focused on Thai students’ conception involving heat and thermodynamics. Twelve
Thai students were interviewed to determine the way they thought about heat energy, temperature, heat
transfer, thermal properties, insulators, conductors and thermal equilibrium through everyday thermal
situations. The compiled data from the interviews were used for developing a Heat and Thermodynamics
Concept Questionnaire (HTCQ) which administered to 214 students from three high schools in Bangkok.
The HTCQ findings revealed that most of the students lacked the understanding of heat and
thermodynamics concepts. For example, at least 84% of the students lacked the understanding of absolute
temperature. Most of the students defined temperature as a variable that can be measured and heat was
a sensation. Only 10% of the students understood that heat is extensive quantities. The results showed
that even the Thai students had a good understanding of insulators and conductors, but they could not
apply their understandings to identify the appropriate materials to keep hot/cold things. This study
indicated that the Thai high school students held similar alternative conceptions of heat and temperature
to the western students. Many students gave the correct answers by referring their everyday experiences
but they had problems with giving reasons and consistent predictions. Two fundamental ideas about the
Thai students learning heat and thermodynamics were generated: 1) students’ understandings are supported
by the likeness between personal experiences and scientific conceptions and 2) students’ alternative
conceptions are reinforced by contrasting their personal experiences and scientific conceptions. This
study indicates that students should be presented with heat and thermodynamics concepts along with
thermal situations, and be able to identify contrasts and comparisons between them. |
