【摘要】：數(shù)字化實驗融入于中學(xué)化學(xué)教學(xué)已是必然趨勢,數(shù)字化實驗的應(yīng)用必將拓寬實驗的范圍,對中學(xué)化學(xué)科學(xué)探究實驗產(chǎn)生革命性的影響。隨著數(shù)字化技術(shù)在教學(xué)中的廣泛應(yīng)用,學(xué)生的綜合能力將得到提升。數(shù)字化實驗的核心是數(shù)字技術(shù)與化學(xué)實驗的深度融合。各種數(shù)字傳感器運用于化學(xué)課堂教學(xué),將會對化學(xué)課堂教學(xué)起到?jīng)Q定性的變革。為了加快數(shù)字化實驗在中學(xué)化學(xué)教學(xué)中的運用,本文利用數(shù)字化技術(shù)開發(fā)探究性實驗案例,進一步解釋實驗的本質(zhì),進一步加強學(xué)生的知識建構(gòu)。本文采取文獻法、實驗法、調(diào)查法等多種方法進行研究和論證。論文大致內(nèi)容概括為三個部分:首先是對課題背景的闡述及數(shù)字化實驗的界定;其次是對數(shù)字化實驗的開發(fā)及教學(xué)應(yīng)用;最后是對數(shù)字化實驗的應(yīng)用效果進行論證和分析。論文的核心部分是基于數(shù)字化實驗在中學(xué)化學(xué)科學(xué)探究教學(xué)案例中的開發(fā)和應(yīng)用研究,筆者開發(fā)了五個數(shù)字化實驗的案例,分別是探究氫氧化鋁與氨水的反應(yīng)、探究不同方法制取的氫氧化鋁飽和溶液的電導(dǎo)率和渾濁度、探究碳酸鈉和碳酸氫鈉的p H隨濃度的變化關(guān)系、探究鹽酸和醋酸混合后的p H變化、探究苯酚與三價鐵離子的顯色反應(yīng)。然后,分別對基于數(shù)字化實驗探究的實驗案例進行開發(fā)和教學(xué)設(shè)計,并進行實踐和應(yīng)用研究。
[Abstract]:It is an inevitable trend for digital experiment to be integrated into chemistry teaching in middle school. The application of digital experiment will certainly widen the scope of experiment and have a revolutionary influence on chemical science inquiry experiment in middle school. With the wide application of digital technology in teaching, students' comprehensive ability will be improved. The core of digital experiment is the deep fusion of digital technology and chemical experiment. The application of various digital sensors in chemistry classroom teaching will make a decisive change in chemistry classroom teaching. In order to speed up the application of digital experiment in chemistry teaching in middle school, this paper uses digital technology to develop inquiry experiment cases, further explain the essence of experiment, and further strengthen students' knowledge construction. In this paper, literature method, experimental method, investigation method and other methods are used to study and demonstrate. The main contents of the paper are summarized as follows: first, the background of the subject and the definition of the digital experiment; secondly, the development and teaching application of the digital experiment; finally, the demonstration and analysis of the application effect of the digital experiment. The core part of the thesis is based on the development and application of digital experiment in the case of inquiry teaching of chemical science in middle school. The author has developed five cases of digital experiment, which are to explore the reaction between aluminum hydroxide and ammonia, respectively. To explore the conductivity and turbidity of saturated solution of aluminium hydroxide prepared by different methods, to explore the relationship between pH and concentration of sodium carbonate and sodium bicarbonate, and to explore the change of pH after mixing hydrochloric acid and acetic acid. To investigate the color reaction of phenol with iron trivalent ions. Then, the experimental cases based on digital experimental inquiry are developed and teaching design, and the practice and application research are carried out.
