Hi there, Please read the attachment files for assignments. 🙂 For Astronomy paper i need to submit tomorrow (March 9th) 11:59 pm, so if u could give me back 10 pm it would be great. For Argument pape
AN-2 assignment information WOMN 1600 D01 Winter 2021 What is an AN (Argument An argument note is written after you have read / viewed, and thought about the arguments and facts put forth – in an academic, intellectual manner – on a given topic. In your AN papers, you are tasked with demonstrating your understanding of the readings / videos I have assigned. In addition to this handout, please read through the section Academic Integrity in the Syllabus, and the Argument Note information in the Assignment section of UMLearn (under Content). Note)? You are not expected to summarize the entire chapter / video / reading. You must select and summarize 3-4 key points from 2 items (readings / videos) from the list below. These 3 sections form your AN paper: Summary: Identify and summarize the key argument(s) or main point(s) of the readings. Ask yourself what the author is trying to convince you of and how. Pick three or four of the more important key arguments or points of the reading, and briefly map them, i.e., elaborate their supporting claims; detail how the argument(s) “work.” The summary section should be given the most space – approximately 2/3 of the paper. Students should not include their own thoughts or reactions to the readings in the Summary. Integration: How do the arguments you summarized challenge, complement, complicate or relate to an argument or concept from another course item? Look for points of similarity or difference and be sure to state how and why these arguments relate to one another. Why do these conditions persist? Which course concepts help to explain why these conditions exist? You must strive to integrate course concepts (i.e. concepts such as patriarchy, power and privilege) into your analysis here. This section should be analytical. Questions/Reactions: Share your reaction to the readings. You can identify questions the readings raise for you. This can also be the place to put your specific questions about the topic. You should discuss your reaction to the content, not the style of the reading. For example, stating that the reading was long / short / complicated / un-interesting etc.. does not provide me with an understanding of your grasp of the material. Do not focus on items that were not discussed in this reading. No one course reading will ever cover all aspects of one topic. For example, pointing out that a reading on women in China did not discuss the situation for women in India, is not a valid point. Stay focused and on topic with the readings What should my AN paper look like? Your final AN paper should be 3-5 pages of writing, and 5-7 pieces of paper, as follows: Page 1: title page: your name, the course, assignment title, date Pages 2-4: Your Summary section. Next page: Your Integration section. Last page of writing: Your Questions and Reactions section. Final page: Your Reference List. In full APA format. Should my AN papers have an introduction and conclusion? These are not required for AN papers. Your paper can have a brief (1-2 sentence) introduction and conclusion if you like. Can I use headings in my AN papers? Yes. Headings can be used to distinguish the 3 sections (summary, integration and questions/reactions). Headings are optional, but paragraphing is not. Use proper paragraph structure as outlined here: https://owl.purdue.edu/owl/general_writing/academic_writing/paragraphs_and_paragraphi ng/index.html How are my AN papers graded? We use the Significance of Letter grades chart (below and in the Syllabus) to assign a letter grade to your paper. Please review this chart. Numeric grades are based on the bottom of the grade range. i.e. an A is 12/15 a B is 10.5/15, a C is 9/15 and so on. In your paper you must cite the page number (or time stamp) for all direct quotes AND all paraphrasing from all sources. This influences your grade on AN papers, and is part of the U of M policy on academic integrity (i.e. avoiding plagiarism). Your paper must have a Reference List that includes all the videos and books / articles you read and cited in your paper. Which items do I choose from for my Choose 2 from the list of options below. Remember you are not expected to summarize everything you read. Select 3-4 key points from each item you choose, and summarize them. The reading by Tabobondung et al (2014) Indigenous midwifery as an expression of sovereignty. (online course reading pdf). APA reference provided in the description area under the reading in UMLearn. Chapter 1 from the book “Not a new Problem: Violence in the lives of disabled women”. APA reference: Owen, M. Hiebert-Murphy, D & Ristock, J. (2018). Disability, violence and social change. In Not a new problem: Violence in the lives of Disabled Women (pp. 1-14). Fernwood Press Canada. Airton, Lee (2018). Chapter 1 pages 26 – 43 (section begins with “Fact or Process”… and goes to the end of the chapter). From the book “Gender Your Guide” Airton, Lee (2018) Chapter 6 “Noticing and Changing Gendered Language” from the book “Gender Your Guide”. The TED talk by Kimberle Crenshaw (2016). The Urgency of Intersectionality. Publisher: TED talks. https://www.ted.com/talks/kimberle_crenshaw_the_urgency_of_intersectionality?language=en#t-1123190 Use the information provided by these sources to construct your APA citations and references. How do I get started? Suggested steps for writing AN papers: Read through the directions. If you do not follow the directions, your paper may not be assigned a passing grade. Select 2 items from the list above. Approach your writing as a process. You must write at least 3, but no more than 5.25 pages (double spaced) in total. Drafting stage: Draft an outline to sketch out your thoughts. I often suggest that students draft their “Questions and Reaction” section first, as this can help with “writers block”. Papers in this course should use the first person voice because it is an important way that writers acknowledge their subjectivity (their own experiences and observations). In feminist writing this is referred to as your “subject location” and it is an element of feminism to (re)claim our voice through writing using “I”. Draft your “Summary” section. Select which ideas from the readings you will quote directly and which ideas you will paraphrase. Keep track of where you are citing from. Cite the page number for all direct quotes AND when paraphrasing from any source. After writing your Summary, take the time to develop your “Integration” section (approximately 1 page). This is where you integrate course materials, and continue to cite them accurately, including the page number. In this section you select which course concepts help you to analyze how or why a specific condition exists. See here for more on analysis vs. summary: https://writingcenter.ashford.edu/summary-vs-analysis Complete your editing sweeps: The first editing sweep is for idea development. The next sweep is to edit for paragraph and topic sentence development. The next sweep is to edit and fix grammar and punctuation errors. Do a final editing sweep to add any missing citations (in APA you must cite all outside material in-text). Each paragraph in the summary must have in text citations with the author, date and page number. Use the APA info at the OWL Purdue website or an APA Style manual. You can book a meeting with an online writing tutor through the U of M Academic Learning Centre. You can email your Instructor questions about your draft, but this must be done at least 2 business days before the due date. Submit the final copy of your AN-1 paper on or before the due date, to the correct dropbox in UMLearn.
