Assignment 3: Course Project Task I
Research Question and Hypothesis
After reading the feedback on your proposed quantitative research question in M1 Assignment 2, provide your revised quantitative research question. Next, develop a hypothesis for the research question (Include a null and an alternative hypothesis for your question.).
Keep in mind that a hypothesis is a specific statement of prediction. A hypothesis describes in concrete (rather than theoretical) terms what you expect will happen in your study. It should be testable and often mirrors the research question in the way that it is written.
For example, there is a positive correlation between having an alcoholic parent and alcoholism in adulthood.
Once you have clearly stated your research question and hypothesis, discuss the following (in 1–2 pages):
· Why is a null hypothesis required in research? How is the null hypothesis used when drawing conclusions from the collected data?
· What is the relationship of your hypothesis to the identified problem?
· How is your hypothesis feasible?
· How is your hypothesis measurable and testable?
Submission Details:
· By the due date assigned, save your hypothesis and supporting discussion as M1_A3_Lastname_Firstname.doc and submit it to the Submissions Area.

Assignment 1: Review of the Literature
In Module 1, you learned about the literature review process, which you will employ as part of your final research proposal in M5 Assignment 2 RA 2. In preparation for writing this literature review, in M3 Assignment 2 RA 1, you will submit an annotated bibliography of 6 peer-reviewed articles from the Argosy University online library resources and locate articles related to the topic of your research in the following categories:
· 2 quantitative studies
· 2 qualitative studies
· 1 mixed-methods study
· 1 theoretical or research design of your choice
As you work toward your discussion in this module, start searching the library databases for articles that may be a good fit for your M3 Assignment 2 RA 1and M5 Assignment 2 RA 2.
Then, in this module’s discussion, consider the following:
A strong literature review not only plays a foundational role for setting up a research proposal and/or dissertation but also plays an important role in the results and discussion section that is presented after the data has been collected and analyzed.
· Why is the literature review a needed piece of a research proposal? How can a weak literature review diminish a research proposal?
· Once the data has been collected and you are moving into the completion of the research report, how will you continue to pull from your literature review in the results and discussion section of your report?
· What search strategies did you use to locate articles from the Argosy University online library resources for your upcoming RAs?
Review the points of others and add additional examples, challenging a response or drawing conclusions from the response.
Post your response in a minimum of 300 words.
All written assignments and responses should follow APA rules for attributing sources.
Submission Details:
· By the due date assigned, post your responses to this Discussion Area.
· Through the end of the module, respond to at least two of your classmates’ posts. While responding, compare the similarities and differences between what you have constructed and what your classmates have.

Grading Criteria Maximum Points
Quality of initial posting, including fulfillment of assignment instructions 16
Quality of responses to classmates 12
Frequency of responses to classmates 4
Reference to supporting readings and other materials 4

What strategies can teachers and students use to increase attention to relevant material in an online course?

 Psychology homework help
Revisit the Module One Areas of Interest and Practical Applications in Cognitive Psychology discussion topic, where you examined your interests, potential problems, and applied settings related to cognitive psychology. Building on those conversations, draft a topic suggestion by identifying your particular area of interest in cognitive psychology (attention, learning, memory, language, or decision making), select an applied setting (education, law, mental health, or technology), and describe the contemporary problem as it relates to your topic and setting. Last, draft three potential research questions that explore potential improvements related to your topic and the applied setting.
For example, if you suggested the topic of attention and online students, the applied setting would be education, and you might develop the following research questions:

  • How does multitasking while studying (e.g., listening to music while reading, or texting while reading) influence attention to course material?
  • How do individuals with ADHD perform in an online learning environment, and what strategies can help them succeed?
  • What strategies can teachers and students use to increase attention to relevant material in an online course?

At least two of these facets of your cultural identity should represent positions of privilege (or dominant culture) in our country. Describe how the three intersecting areas of your cultural identity (gender, sexual orientation, race, religion, and ability) impact your understanding of and relationship with marginalized groups of people in a paper of 1-1.5 pages. Your paper will be evaluated using standards below:
APA Style

  • In-text Citations
  • Reference Page

Organization
