Your essay must be 1,000+ words. Your essay must closely engage with the assigned text(s) through direct quotation and analysis by incorporating at least four direct quotations, each followed by close analysis of the text’s language and meaning. Your essay should present a compelling, coherent, and specific thesis that is consistently and thoroughly developed.  Summarizing the readings or relying on personal reaction will result in a lowered score or a grade of zero. Responses should omit personal reflection in favor of analysis and provide ample support from our readings. Exams that fall short of the minimum word count and/or fail to incorporate textual support (cited quotations) from our readings will suffer a significant grade reduction. Your work will be graded on the quality of your ideas as well as your writing. Criteria for grading include completeness, thoughtfulness, and development and support of a particular argument. Per the plagiarism policy, you must cite ideas that are not your own. You must include MLA format in-text citations. The following deductions will apply: 1) Missing textual support (quotations) from the primary text= -20% of the grade 2) Short of the word requirement= loses points based on percentage short (ex: an essay of 500 words can receive up to 50% credit with 1,000 words required) Prompts (select ONE): 1) Using one or two of the short stories assigned in module 1, consider how the text(s) define home. What, in the texts, does it mean to feel at home? How do the authors depict home as both a physical and symbolic space? Be sure to quote at least four examples from the text(s). Closely analyze the examples you cite with a focus on how place informs identity.  2) Using one or two of the short stories assigned in module 1, consider how the text(s) explore the legacies of colonialism and/or imperialism. How do those legacies influence characters’ choices and experiences? Be sure to quote at least four examples from the text(s). Closely analyze the examples you cite with attention to the relationship between identity, power, and  hierarchy.  3)  Using one or two of the short stories assigned in module 1, consider how the text(s) depict the tension between individual and collective identity. What, in texts, does it mean to belong? When and why do characters feel compelled to adhere to cultural or familial expectations? Be sure to quote at least four examples from the text(s). Closely analyze the examples you cite with attention to the relationship between identity, culture, and belonging. Note- Your essay should address one of two of these short stories: Read Merle Hodge’s “Limbo Island” (PDF) Read Paule Marshall’s “To Da-duh, in Memoriam” (PDF)  Read Maryse Condé’s “Three Women in Manhattan” (PDF) Read Liliane Dévieux-Dehoux’s “Piano-Bar” (PDF)
