In this paper, according to the fully time compulsory education curriculum standards of chemistry ( experiment draft ) which requests that the students should be able to pose some valuable questions from their daily life or from their chemistry learning and express their questions clearly, the author discussed the inquiry value of the questions in chemistry instruction based on the theory of scientific epistemology, cognitive psychology and ability psychology. furthermore the parameters for measuring the students " questioning ability are also talked about from the perspectives of the motivations of questioning, the cognitive foundation, the value of the questions, the ability of posing questions by themselves and the ability of expressing their questions. after reading many literatures and interviewing some experienced chemistry teachers, the author proposed instructions strategies in cultivating the students " questioning ability in chemistry instruction from five aspects, they are : to stimulate the students to question ; to construct the cognitive foundation of questioning ; to augment the value of the questions ; to make the students pose their questions by themselves ; to cultivate the students " ability of expressing their questions
本文在研究的過程中，採用了文獻閱讀和向任課教師訪談的方法，以《標準》中對「提出問題」要素的要求「能從日常現象或化學學習中，經過啟發或獨立地發現一些有探究價值的問題；能比較清楚地表述所發現的問題」為主線，運用科學認識論、認知心理學及能力心理學的相關理論作為理論基礎，結合中學生化學學習的特點，從問題的遷移價值、思維價值、能力培養價值和情感價值四方面深入探討了化學教學中問題的「探究價值」 ；通過對化學教學中學生「提出問題」能力的涵義及結構的分析，從提問動機、提問的認知基礎、所提問題的價值、提問的自主性和表達問題的能力五個方面建立了衡量學生「提出問題」能力的指標體系；在此基礎上相應從五方面提出了化學教學中學生「提出問題」能力培養的教學策略，分別是激發學生「提問」動機的策略、建構「提問」認知基礎的策略、提高問題價值的策略、提高學生「提問」自主性策略和培養學生「表達問題」能力的策略。 -
Firstly, this thesis was based on thoughts and theories of chemistry teaching material experiment parts of establishments that was discussed, and stressed on studying the united states reformation of the high school chemistry teaching material practices since half a century ; and summed up five characteristics on experiment parts of establishments : first has more than hours of the experiment lesson, and student need use half time do the experiment ; second is to emphasize strict and careful science attitude, and educate students as scientists to do the experiment ; third is that a chemistry experiment should face to the society, face to the life and face to the other related course ; fourth is that investigating types and its ability have been used as the important contents on chemistry experiment reform and development ; fifth is that chemistry teaching material establishment emphasize universal science and technique knowledge, and increase citizens chemistry science attainments
本文首先在論述化學教材實驗部分編制的思想理論基礎上，重點探討美國半個世紀以來中學化學教材的改革實踐，並總結出了其實驗部分編寫的五個特點：一是實驗課時較多，學生需用一半的學習時間做實驗；二是強調嚴謹的科學態度，教育學生象科學家那樣去做實驗；三是化學實驗面向社會、面向生活、面向其它相關學科；四是探究式學習和探究式能力培養一直作為化學及化學實驗改革和發展的重要內容；五是化學教材編制強調普及科學技術知識，提高公民的化學科學素養。 -
