Please respond to ONE of the following prompts. Remember that your response must cite at least two of the sources that you were given in the prompts. You must cite your sources as well. This is an essay response, so you must write at least 5 paragraphs. Your response must also be at least 500 words.   1.   Recent research has focused on using Massively Multiplayer Online Role Playing Games (MMORPGs) and other online environments, such as Twitter or Wikipedia, as laboratories to study social and cultural behaviors, proclaiming the value of virtual realities for insights into real-world relationships. While some researchers assert that virtual world connections are not different from real world interactions, others argue that these simulated realities have little to do with physical interactions.  Are online environments accurate representations of human behavior in the physical world? Do these virtual worlds make people more or less prepared for social interaction and experiences in the real world? Make sure that you use specific examples along with at least two of the assigned items (which you may quote, paraphrase, or summarize) to develop your argument. Take care to integrate your sources into your essay effectively and to document your sources (including images) in appropriate MLA format. You do not need to include a Works Cited list.   2.   Online environments, including games, provide virtual spaces for interacting across social, economic, and cultural boundaries. Many of these online environments have made their way into higher education, including online and face-to-face classrooms.  Some academics see these virtual worlds as an opportunity for students to develop research and put into practice what they are learning in the classroom. Faculty use environments such as Second Life or Facebook to create classroom assignments.  Do you think that virtual interaction can be an effective classroom tool to provide students with practical experience and enhance learning? Why or why not? In making your claim, please use specific examples along with at least two of the assigned items (which you may quote, paraphrase, or summarize) to develop your argument. Take care to integrate your sources into your essay effectively and to document your sources (including images) in appropriate MLA format. You do not need to include a Works Cited list.
