Application of a Blending Learning Model Based on Web Intelligent Technology in the Indirect Iodometric Method

Under the background of "Internet+", along with the integration of network intelligence technology and the increasing maturity of network teaching platform, the teaching mode has changed drastically, and blending learning is a typical representative. This paper focuses on the process of determining copper content in lead ice copper by indirect iodometric method, design three teaching links with the help of modern network technology and mobile terminals: online self-learning before class, flipped classroom during class with online intelligent technology, and online survey and quiz after class, and link online and offline classes with Learning Pass terminals. We make full use of online intelligent technologies such as check-in, voting, quick answer, random selection, questionnaires, in-class quizzes and topic discussions to achieve big data tracking records of learning and form personalized learning reports.
