Context Memo I am writing for Techtrends. I chose this one because it is a leading journal for scholars concerned with educational communication and technology. My topic is to explore how electronic devices change classroom. Articles published in Techtrends can be a good source for my research. The citation style required for Techtrends is MLA format. 1. Use of evidence I use this rhetorical device mainly because it helps to build a convincing and reliable conclusion. Besides, the goal of this review is to explore previous studies on the topic, hence a rich collection of evidence can establish a serious writing style. 2. Use of structure I structure my review in a traditionally academic format followed by reference. This structure can help to make my review more similar to a real one and facilitate readers to identify the information they need in a relatively short period of time. 3. Use of word I purposely use words of academic style to make the article fit in the taste of scholarly readers.
