How do individuals with ADHD perform in an online learning environment, and what strategies can help them succeed?

/in /by

 

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?

SOC490 Methodology for Selecting a Sample Population

Question descriptionYour research proposal for your Capstone Project should be written on a topic in which you feel an investment and that also is relevant to fields within the social sciences. What relevance does this issue have in your own life? Does it relate to your interests, and if so, how does it relate? What is your connection to the population you are researching? If the issue does not have relevance to you or you do not have a connection with the population, explain why not. What is the goal of your research? Are you using your research for the good of this population or solely for the enhancement of knowledge in general? Which is more important and why? Are they both equally important?

Your Capstone Project will focus on a specific sample population for future research. In this discussion, you will need to do two things. First, explain the attributes of the sample population that you plan to study. Then explain the research methodology you will use to study that population. Will you use a quantitative approach, qualitative approach, or a mixture of both? Which approach do you find most valuable and why?

How does research affect existing medical knowledge and practice?

/in /by

Need help writing a paper

Preparation

Search the Capella library and the Internet for scholarly and professional peer-reviewed articles on evidence-based nursing practice. You will need at least three articles to use as support for your work on this assessment.

Directions

As a health care professional and a new BSN learner you have been asked to contribute a professional blog post on evidence-based practice to a new Web site for student nurses. The site editor has asked you to write a post that explores the following key questions:

  1. How does research affect existing medical knowledge and practice?
  2. How can evidence-based patient care improve the quality of care?
  3. What types of clinical strategies help foster an evidence-based nursing practice?
  4. Which component of the nursing process is evidence-based practice aligned with?

When writing a blog post, keep in mind that long blocks of text are hard for readers to digest, especially when reading on mobile devices. Format your document by breaking up your content into shorter paragraphs, bullet points, and lists whenever possible. Subheadings should be used to provide focus.

Additional Requirements

Your blog post should meet the following criteria:

  • Contain 750–1000 words (3–4 pages).
  • Include a title and reference page.
  • Be readable, concise, with a logical ordering of ideas.
  • Provide a sound rationale for ideas, including background supported by professional references.
  • Provide adequate documentation of ideas and appropriate APA citation of relevant literature.
  • Use a minimum of three references. (These must be recent, from within the past five years).
