We summarize its advantages as producing better visual effects, high efficiency in information transfer, precise and systemic knowledge structure. Disadvantages of PowerPoint may be induced by irrelevant information in slides, neglect of interaction with students, uncontrolled speed in presenting or too strict order of slides. Strategies to avoid these disadvantages are proposed.  \nIndex Terms: PowerPoint; advantages; disadvantages; science students  \n© 2012 Published by MECS Publisher.

Introduction  \nPowerPoint is now one of the most widely applied software in classroom teaching. PowerPoint presentation has many advantages over traditional \"chalk-and-talk\" lecture. However, PowerPoint is not almighty. An early study compared classes taught with and without PowerPoint materials, and showed no significant change in student performance with PowerPoint though most students prefer PowerPoint to chalkboard [1] . Another study reported that, PowerPoint may have created a generally favorable impression of the class and the professor, but not significantly affecting grades [2]. If inappropriately used, PowerPoint would decrease the effect of the lecture. It is thus important to realize advantages and disadvantages of PowerPoint, as well as strategies to avoid its disadvantages.  \n2. Advantages of PowerPoint  \n2.1. Producing Better Visual Effects and Deeper Impression  \nThe contents of a science lecture is often abstract, sometime they are hardly to explain using chalkboard.  \nHowever, by presenting PowerPoint slides inserted with pictures, flow charts, schematics, animations, even video clips, the lecture may become vivid and attractive to students. For example, in chemistry, the shift between Corresponding author:  \nE-mail [address:](address: amsedxg@zju.edu.cn)[ a](address: amsedxg@zju.edu.cn)[msedxg@zju.edu.cn](address: amsedxg@zju.edu.cn), [b](b l iujx@zucc.edu.cn)[ l iujx@zucc.edu.cn](b l iujx@zucc.edu.cn)  \n62 Advantages and Disadvantages of PowerPoint in Lectures to Science Students  \ntwo conformations of a molecular is hard to explain using chalk writing, but it could be easily demonstrated by two figures in PowerPoint. For another example, when explaining physicochemical process \"sintering\", a series of pictures of scanning electronic microscope could be displayed to show the process that granules adsorption, adhesion and the crystal formation. Students would thus easily understand this special term, and they would be impressed with the mass transfer and heat transfer process.  \nSeveral studies supported the hypothesis that graphics and animations improve students' recall [3,4] . Also, PowerPoint lecture may benefit recall, or perhaps recognition, from memory [5] . With the help of advanced projector with high contrast and resolution, a better effect of PowerPoint presentation could be obtained.  \n2.2. Speeding up the Information Transfer  \nIn a PowerPoint presentation, the teacher can deliver more information than by traditional lecture. The amount of information transferred in a traditional lecture is often limited by the writing speed of the instructor on chalkboard. But in a PowerPoint presentation, all outlines were typed previously in s","cbCaiaCRBmqGDZ2e","https://ap.wps.com/l/cbCaiaCRBmqGDZ2e","pdf",36390,"English","# Introduction\n# Advantages of PowerPoint\n## Producing Better Visual Effects and Deeper Impression\n## Speeding up the Information Transfer\n## More Precise and More Systematic\n# Disadvantages","[{\"question\":\"What advantages does PowerPoint provide for science lectures?\",\"answer\":\"It improves visual effects with figures, charts, animations, and media; it increases information transfer efficiency; and it supports more precise, systematic presentation of knowledge.\"},{\"question\":\"What disadvantages can arise from using PowerPoint in lectures?\",\"answer\":\"Disadvantages include irrelevant information in slides, insufficient interaction with students, uncontrolled speed during delivery, and overly strict slide ordering.\"},{\"question\":\"How can teachers reduce the negative effects of PowerPoint?\",\"answer\":\"By avoiding irrelevant slide content, maintaining interaction, controlling presentation pace, and adjusting slide sequencing; the paper also proposes strategies to prevent these issues.\"}]","Advantages and Disadvantages of PowerPoint in Lectures to Science Students - Part 9 | PDF",1789872264,13]
