手持技术的教学模式是一种把先进的数字设备引进教学中的教学模式。在化学教学中,应用这种模式来开展教学,能够提高化学教学的效率。一、以手持技术为核心,引导学生做课前预习手持技术是一种与计算机相结合的,能根据人们的需求自动采集数据、分析数据的一种数字设备。化学教师若能将这种设备引进化学教学中,将能形成新的教学模式,最终提高化学教学的效率。以教师引导学生学习《氢氧化铝制备的实验》为例。这节课的教学难点是使学生了解到在制备氢氧化铝的过程
Handheld technology teaching mode is a kind of advanced digital equipment into teaching teaching mode. In chemistry teaching, using this model to carry out teaching can improve the efficiency of chemistry teaching. First, the handheld technology as the core, to guide students to do pre-class training Handheld technology is a combination with the computer, according to people’s needs automatically collect data, analysis of data, a digital device. If chemistry teachers can introduce this kind of equipment into chemistry teaching, they will be able to form a new teaching mode and eventually improve the efficiency of chemistry teaching. Taking Teachers as an Example to Guide Students to Study “Preparation of Aluminum Hydroxide”. The difficulty of teaching this lesson is to make students understand the process of preparing aluminum hydroxide
