摘要


酸及鹼的概念雖然是一種化學專門的術語,但與人類日常生活卻有密切的關係,例如:『中和』、『pH值』等已成為現代人相當熟悉的名詞。本研究以自行設計的酸鹼概念診斷工具探究學生對酸鹼概念的了解情況,藉此找出學生的酸鹼錯誤概念。此外,並設計酸鹼概念的微量實驗裝置,希望藉由教學活動促進學生對酸鹼概念的轉變。研究對象主要包括國中一至三年級學生,共計698人。 本研究所採用的工具包括三個部份:(1)「酸鹼概念前測及教學活動工具」,內容涵蓋有酸鹼性強度概念與酸鹼溶液導電性概念等兩大主要概念。(2)「酸鹼概念後測工具」,內容包括有日常生活酸鹼概念、酸鹼性強度概念與酸鹼溶液導電性概念等三大主要概念,以此測驗結果探討教學之成效。(3)「比例推理能力測驗工具」,主要在於評定學生基本比例推理能力的認知發展層次,以比較學生的比例推理能力與其酸鹼概念的關係。 主要研究發現如下: 一、學生對物質酸鹼性之推理模式大致可分為以下十三個類型:「感官知 覺」、「中和作用」、「指示劑」、「離子觀念」、「腐蝕性」、 「反應產物」、「導電性」、「清潔作用」、「美容作用」、「脫水 性」、「外觀」、「稀釋」、「其他」等。 二、對於「酸鹼性強度」之判斷,多數學生以「濃度」為考量的依據,少 數會結合「解離度」概念,這是許多學生錯誤概念產生的主因。此 外,經由統計分析得知,就教學前的前測結果而言,學生在「酸鹼性 強度概念」的瞭解,在年級與性別的交互作用皆未達統計上的顯著水 準,但在年級間則有達到統計上顯著差異(p<.001),顯示在此概念的 理解,學生有隨年級的增加而成長的趨勢,而男女生並無顯著差異。 三、對於酸鹼物質水溶液的導電性,一般學生所持的想法,大致有以下八 點概念特徵:「外觀」、「離子觀點」、「能源大小」、「物質之酸 鹼性」、「濃度」、「屬性」、「生活經驗」、「狀態」等。另外, 學生在「酸鹼溶液導電性概念」的理解,在年級與性別的交互作用皆 未達統計上的顯著水準,但在年級間仍達到統計上的顯著差異 (p<.001)顯示學生在此概念的理解亦有隨年級成長的趨勢。 四、針對教學成效而言,不管是實驗組與控制組間的比較,或者是實驗組 本身在教學前後的比較,其平均值皆達到統計上的顯著差異(p<.001) ,由此,我們可以確定本研究利用微量實驗裝置的教學活動有助於學 生在酸鹼概念上的成長。 五、由「酸鹼性強度概念」與「酸鹼溶液導電性概念」的相關分析發現, 不管是實驗組或控制組,學生在此二項酸鹼概念上的相關性,皆達到 統計上的顯著水準(p<.01),可見這兩種概念在酸鹼概念的學習中息 息相關。 六、從比例推理能力與酸鹼相關概念之各子概念間的χ2檢驗發現,多數 酸鹼概念與比例推理的相關有達到統計上的顯著水準(p<.01),因 此,可以推論學生在酸鹼概念的成長,與其本身所具備的比例推理能 力有相當程度的關聯性。 關鍵詞:錯誤概念、日常生活酸鹼概念、酸鹼性強度概念、酸鹼溶液導電 性概念、比例推理能力、微量實驗裝置

並列摘要


The concepts of acids and bases are terminologies in chemistry. They are related to daily life of human, the terms such as“Neutralization”,“pH value”etc. are familiar to people. The purposes of this study are to probe the understanding of the concepts acids and bases of students with a designed diagnosis instrument, and to find out students’ misconceptions. Then, we hope students had better conceptual change through teaching activities. The subjects were from grade 7 to 9. Totally 698 students took this activities. The instruments used in this research consisted of three parts:(1)“The Acid-Base Teaching Activities with Pretest”. In this activities, it consisted of two main topics:strength of acid/base and conductive properties of acid/base. (2)“The Acid-Base Posttest”consisted of three main topics:daily life conceptions of acid/base, strength of acid/base and conductive properties of acid/base. (3)“The Proportional Reasoning Abilities Test”:The purposes of this test is to examine the relation between student’s understanding of the concepts acids and bases and their cognitive development in proportional reasoning level . The main findings of the study were: 1.The main thirteen categories of students’ reasoning model on acid-base materials were:“Sensory Organs ”, “Neutralization”,“Indicator”,“Ion Concepts”, “Corrosiveness”,“The Product of Reaction”, “Conductivity”,“The Effect of Cleaning”,“Cosmetology”, “Dehydration”,“Appearance”,“Dilution”,“Others”. 2.For the judgement of“Strength of Acid/Base”, most students considered more concepts of “Concentration”than that of“ Degree of Dissociation ”or combined both of these two ideas, and it was the major cause of misconceptions . Besides, there was a significant difference statistically (p<.001) among students’ grades in the understanding of “Strength of Acid/Base”. It revealed that the understanding of “Strength of Acid/Base”was developed with students’ grade growth. 3.For the existence of conductive properties of acid-base materials, the main eight categories were as follows: “Appearance”,“Ion Concepts”,“Energy of Battery”, “Acidity or Basicity”,“Concentration”,“Property”,“Daily Experience”,“State”. There was also a significant difference statistically (p<.001) among students’ grades in the understanding of“Conductive Properties of Acid/Base”. It also indicated that there was an improvement of “Conductive properties of acid/base”as students’ grade growth. 4.In according to teaching effects, there were significant statistically (p<.001) between the experimental group and the control group or between pretest and posttest in the experimental group. For this reason, we can confirm that these teaching activities could promote the acquisition of the concepts acids and bases. 5.The correlation were significant statistically (p<.o1)between “Strength of Acid/Base”and“Conductive Properties of Acid/Base”from the test performance of the experimental group or the control group. It is evident that the two concepts were closely related with each other in studying the concepts acids and bases. 6.From the χ2 test between the proportional reasoning test and each sub-concept of the concepts acids and bases, we found that most were significant statistically in correlation coefficient(p<.01). Therefore, we can predict that students’ maturation of the concepts acids and bases is related to their proportional reasoning ability. Keywords:misconception, daily life conceptions of acid/base, strength of acid/base, conductive properties of acid/base, proportional reasoning ability, microscale experimental apparatus
