摘要


摘 要 本研究主要目的有三:第一、透過不同類比教材對於不同認知思考能力學生之溫度與熱概念學習的成效和態度的分析,來了解影響類比學習的因素;第二、了解學生對於溫度與熱概念具有的另有概念和心智模式;第三、在認識論之感覺經驗和本體論預設下,經過不同類比教學後,瞭解溫度與熱的概念改變類型。 研究對象為國二學生,以現行國中理化二年級第五章溫度與熱為題材,分別從文獻中提及的水類比物-典型類比教材、和由已學過溫度與熱單元的國三學生的自發性類比物來設計類比教材和對照組三種教材,透過教學前測驗、類比教學、教學後測驗、問卷和晤談等方式進行研究。 本研究結果如下: 1. 本研究設計的典型類比組整體教學成效優於對照組,但是學生類比組卻較對照組的教學成效為差。形式思考能力學生可透過類比教學而有所助益,而對於過渡思考能力和具體思考能力學生則教學成效無明顯差異。進一步針對溫度與熱各概念的學習成效分析,顯示各類比教材所聚焦的概念會有所助益,但是類比教材的限制和學生的誤解亦會造成迷思概念,影響類比教學成效。 2. 不同認知思考能力影響到學生類比對應的能力,但是類比的理解和遷移則會因類比教材內容的差異,產生不同程度的影響。 3. 不同認知能力的學生對於不同類比物的類比態度並不一致,顯示不同認知思考能力學生對於類比教材的態度與類比教材有關,即使類比物容易被學生接受,但是並不保證類比遷移和學習的成功,顯示設計類比除考慮學生熟悉經驗和認知思考能力外尚存在其他影響的因素。 4. 學生學習溫度與熱必須考慮認識論和本體論預設,在感覺經驗、教學脈絡內容兩者影響程度差異下,不同「溫度與熱」的本體概念屬性來形成各種心智模式。推論溫度與熱之間關係,應將「熱」視為「偏過程」概念屬性,而學生誤以「偏物質」概念屬性來解釋關係;應將「比熱」概念置於影響「熱量和溫度變化之間的過程」中,而錯置於「吸熱的過程」中;考慮熱平衡中物體的溫度變化,應視為「偏CBI」概念屬性,而學生誤認為「偏過程」屬性;學生無法了解「冷熱感覺」是發生於物體間的「偏過程」屬性,而誤認為物體中的「偏物質」屬性概念。 綜上所述,學生認知思考能力的差異與類比教材的設計,影響到類比教學的成效外,並且進一步思考在認識論和本體論預設下,亦會影響到溫度與熱概念的學習。

Abstract The research mainly serves three purposes: first, to understand the factors that influence analogical learning of concepts of heat and temperature analyzing by students with different cognitive thinking abilities in learning from these different analogical materials ; second, to understand students' alternative concepts and mental models on heat and temperature ; third, to make use of Vosniadou's framework theory and Chi's theory of ontological coceptual change to understand students' epistemological and ontological presuppositions of heat and temperature . Seventy eight 8 th graders are involved in this study. Three teaching materials:(1) standard analogical materials, i.e. water analogy mentioned in scientific literature, (2) student-directed analogical materials, i.e. self-generated analogies which are generally designed for the 9 th grader who have learned the concept of heat and temperature, and (3) the materials for the control group. This research is implemented through pretest, teaching, post-post, interviewing and deferring test. The results of the research are as follows. 1. The whole teaching effect on the standard analogical group designed specifically for the research is superior to that on the control group, however, the teaching effect on the student-directed analogical group is worse than that on the control group. Formal operational students could benefit from analogy, but for transitional operational students and concrete operational students, teaching effects are of no significant differences. Further analysis on the learning effects on the concepts of heat and temperature reveals that the focused concept in each analogical material is beneficial, but analogical constraints and students' misunderstandings also lead to alternative concepts, which influences the effect on analogical instruction. 2. Different cognitive thinking abilities affect students' abilities of analogical mapping. Nevertheless, analogical understanding and transfer generate influences of different degrees due to divergent analogical materials. 3. Students of different cognitive abilities hold varied attitudes towards different analogies, which shows that different cognitive-thinking-ability students' attitudes towards analogical material are related to analogical materials. Even though analogy is easier for students to understand, it does not guarantee the success of analogy transfer and learning, which manifests that in designing analogy, other factors should be taken into consideration besides student's familiar experiences and cognitive thinking abilities. 4. When students learn heat and temperature, teachers should take into account epistemological and ontological presuppositions. Under the different-degree influences between perceptual experience and teaching context, students use different ontological concept properties of heat and temperature to form all types of mental models. When inferring the relationship between heat and temperature, we should regard heat as process-oriented concept properties, however, students mistakenly use matter-oriented concept properties to account for relationship. We should put the concept of specific heat in 'the process of changes of heat and temperature', while students mistakenly put it in considering 'the process of absorption of heat.' We should consider the temperature change of the object in heat equilibrium and think of it as CBI-oriented concept properties, but students mistakenly think of it as process-oriented concept properties. Students can not understand that the feeling of being hot and cold occurs in process-oriented concept properties among objects; they mistakenly think it occurs in matter-oriented concept properties of objects. In summary, the analogical materials will be influenced not only by the diversities of students' cognitive thinking abilities and the design of analogical materials, but also by students' conceptual learning of heat and temperature under epistemological and ontological presuppositions.
