Summary:

It is generally accepted that teaching and learning material and activities should be grounded in a deep understanding of students' ideas and the subject matter to be taught. In the domain of thermodynamics, a great deal of research has been done to determine students' (mostly at the primary and middle school levels) misconceptions about heat and temperature; a smaller number has been done to analyse the subject matter as presented in the science classroom. What is very scarce is research which brings together the two aspects to induce a well-grounded instructional re-examination and reconstruction. The present book is thus conducted to examine secondary students' understanding of basic thermal concepts, such as heat and temperature, along with a conceptual analysis of the scientific knowledge as presented in textbooks. The purpose of the book is to provide a knowledge base for instructional design including features and relations of what students think and what is presented to them, so that more efforts can be made to remove errors and bridge gaps.

Chapter 5THE SCIENCE OF HEAT IN TEXTBOOKS

THE DEFINITION OF HEAT

HEAT IS THE ENERGY TRANSPORTED FROM A HOTTER TO ACOLDER OBJECT

HEAT IS (PART OF) THE CHANGE IN INTERNAL ENERGY

HEAT IS THE ENERGY BEING TRANSFERRED FROM A HOT TOA COLD BODY BY MEANS OF IRREGULAR MOLECULARMOTIONS

HEAT IS A KIND OF ENERGY THAT CAN DO "WORK"

HEAT IS ENTROPY

HEAT HAS PRESENTED IN EVERYDAY AND SCIENTIFICWORLD

HEAT AND INTERNAL ENERGY

TEMPERATURE AS AN OBJECTIVEMEASURE OF COLD AND HOTNESS

TEMPERATURE AS THE QUALITY WHICH IS THE SAME INDEGREE AMONG OBJECTS IN THERMAL EQUILIBRIUM

TEMPERATURE AS A RESULT OF MOLECULAR MOTION

PARTICLE MODEL IN THE CASE OF PHASE TRANSITION

Chapter 7CONCLUSION

THE TEACHING OF THE THERMAL SCIENCE SHOULD BEBASED ON A SUFFICIENT UNDERSTANDING OF THE SUBJECTITSELF AND STUDENTS' LEARNING OF THIS SUBJECT

MORE EFFORTS SHOULD BE MADE TO ASSIST STUDENTS INDIFFERENTIATING HEAT, TEMPERATURE AND INTERNALENERGY

THE DIVERSE MEANINGS OF HEAT SHOULD BE CLARIFIEDIN REFERENCE TO THEIR ONTOLOGICAL COMMITMENTS ORCONTEXTUAL BACKGROUND

HISTORICAL MATERIAL CAN BE EMPLOYED TO CONVEYUNDERLYING MEANINGS OF THE HEAT CONCEPT

EXPLAINING A CLUSTER OF CONCEPTS THROUGH A RANGEOF CONTEXTUAL PROBLEMS SHOULD SUPPORT STUDENTSIN CONSTRUCTING THEIR CONCEPTUAL MAPS

DISCREPANT EVENTS CAN BE USED TO ASSIST STUDENTS INDISCOVERING THE WEAKNESS OF THEIR CONCEPTIONS

INSTRUCTIONAL EFFORTS SHOULD BE MADE TO ENHANCEAND MAINTAIN THE CONSISTENCY AND COHERENCE OF THESCIENTIFIC LANGUAGE USED IN THE CLASSROOM
