【摘要】：信息技术与学科课程整合是当前国际上科学教育改革的一种趋势与潮流。为了有效地将数字化传感技术应用于化学探究学习中，本文从哲学、历史学、教育学三个视野，分别对科学的本质、化学学科的发展和科学探究学习进行深入的研究，根据数字化传感技术的特点，设计了3种数字化传感实验与探究学习整合的教学模式并进行了相关的教学实践，使用观察法、问卷法、访谈法对教学实践的效果进行了分析。图像分析探究模式借助数字化传感技术作为化学课堂的定量型的实验辅助工具，帮助学生结合实验图像理解了所学知识，提高了学生分析信息、加工信息和整合信息的能力；数据分析探究模式让学生能通过数学计算理解所学化学概念或原理，，学生在分析与加工信息的基础上，应用信息解决问题的能力和进行科学探究的能力得到显著提高；理论发展探究模式让学生通过运用数字化传感实验得到的定量数据和实验曲线，通过质疑、批判与重新建模，发展对化学概念或原理的新理解与认识，在提高问题解决能力的基础上，思维的批判性和创新性得到改善。教学实践还表明，三种模式不仅使得探究学习更加深入，学生的科学素养也得到了全面的提高。
[Abstract]:The integration of information technology and subject curriculum is a trend and trend of the current international science education reform. In order to effectively apply digital sensing technology to chemical inquiry learning, this paper starts from philosophy and history. The three perspectives of pedagogy are the nature of science, the development of chemistry and the study of scientific inquiry, according to the characteristics of digital sensing technology. This paper designs three teaching modes of integrating digital sensing experiment and inquiry learning and carries on the related teaching practice. The effect of teaching practice is analyzed by means of observation method questionnaire method and interview method. Image analysis and inquiry model with the help of digital sensing technology as a quantitative chemical classroom experimental aids to help students understand the experimental images to understand the knowledge and improve the student analysis information. Ability to process and integrate information; The model of data analysis and inquiry enables students to understand the concepts or principles of chemistry through mathematical calculation. The students are based on the analysis and processing of information. The ability to use information to solve problems and to conduct scientific research has been significantly improved; The mode of theoretical development and exploration enables students to develop a new understanding and understanding of chemical concepts or principles by using the quantitative data and experimental curves obtained from digital sensing experiments and by questioning criticizing and remodeling. On the basis of improving the ability of problem-solving, the critical and innovative thinking has been improved. Teaching practice also shows that the three models not only make inquiry learning more in-depth. Students' scientific literacy has also been comprehensively improved.
