Day #7, June 25 th CEP 955 Summer Hybrid, 2013 Jack Smith Michigan State University

Overview Brief updates Holland & Eisenhardt (“Box 5.2”) GGB, chapter 3 Greeno, Collins, & Resnick, pointers useful Important issues in GGB, chapter 6 Samples & Populations Methods of sampling Hoped for and actual samples Human subjects issues (MSU’s SIRB) Writing & outlining time: Sites and participants section Theory bites from Holly and Barb

Samples & Sampling (GGB, ch. 6) Basic idea: Who gives us data has a lot to say about the significance of our work Major distinction: Random samples for quantitative studies and purposeful samples for qualitative studies Important distinction: Random sample (from known population) vs. random assignment of participants to groups Target Population & Accessible Population Not just for quantitative studies Relevant to research in single institution How will talk about the meaning of my results Desired Sample & Actual Sample Invitation and acceptance Attrition

The Non-Volunteers Problem Participation in research in voluntary Desired participants may choose not to participate Issue: What information about the target phenomenon do you lose in the process? Examining the nature of non-volunteers via public information; “data collection” is not allowed GGB ideas about addressing the problem What you may be losing (Table 6.3) Positive recruitment strategies (Table 6.4)

Human Subjects (a preliminary sketch) Three basic principles Research must be an ethical practice Confidentiality (esp. in oral and written reports) Informed consent Voluntary participation Universities and Institutional Review Boards (IRBs) Human subjects application and approval: Satisfy MSU SIRB “Responsible investigator” = your advisor Jack’s advisee mistake & subsequent audit Your special challenges Teacher and researcher in small place Participation voluntary? Consent and assent

Questions (for your “site & participants” section) Who or what are the Units in my sample? What is my Population? Target Accessible Sites: where will I go to get my data? Best (rational) choice Actual choice Sample: How many units do I need? Expected response to invitation (of human subjects) Expected attrition Assignment of units to Groups (for research that will compare)

Theory Bite(s) Introducing Holly’s Practicum Holly: CBAM, Concerns-Based Adoption Model Q&A; discussion Introducing Barb’s Practicum Barb: Growth mind set Q&A; discussion

Homework for tomorrow Things start to diverge: Measures & data collection and data analysis (W & Th) Writing homework: Examine your current RQs List all the constructs that you need to measure List your current options for measure (what type?) Reading homework: GGB “menu” Chap. 7, Tests & self-report measures Chap. 8, Questionnaire & interview measures Chap. 9, Observation & content analysis Spend ¾ of your reading time in the most applicable chapter; ¼ on a second Wednesday & Thursday may have some “we have to address this topic” from prior days; don’t fit the overarching focus
