  2. AN INVESTIGATION OF HIGH SCHOOL DUAL ENROLLMENT PARTICIPATION AND ALLIED HEALTH PROGRAM ENROLLMENT IN A SOUTH TEXAS UNIVERSITY Dissertation Defense by Marti Flores Fall 2010 *Define DE Programs and AH Programs (Exclusive/5 AH )

  3. National Shortage of Healthcare Professionals Population Growth Survival Rates BB Retiring Prediction Overall Transition HS Students into Higher Education: Particularly AH Professions Dual Enrollment

  4. Introduction Demand HC (BB=Silver) & (Surv. Rates=Interventions) (Lang, 2009) Seamless Transition HS – PS Education Gap (Conley et al., 2006) Postsecondary enrollments 5.3 million healthcare workers (PRWEB, 2007) Support System -Dual enrollment (Andrews, 2004)

  5. Need of the Study • Hughes, Karp, Fermin, & Bailey, 2005 = Nat’al Study Pathways-Persistence? • Olson, 2006 = Scarce data – Accel program effectiveness • Smith, 2007 = At-risk, low income, and minority students • Swanson, 2008 = Limited evidence persistence - graduation • Lee, 2009 = Lack of studies concerning factors = AA Purpose of the Study • Existing Literature/Value DE • Investigate factors motivated (student report) • Factors contributing to success • Proportion of total variance in AA attributed to 5 IVs

  6. Review of the Literature Supporting Views Review of the Literature Opposing Views

  7. Research Questions (Prior to Data Reduction) 1.What motivated college students to enroll in health science technology (HST) dual enrollment courses while they were in high school? 2. What factors or variables do college students who enrolled in health science technology (HST) dual enrollment courses believe contribute to their academic success? 3. What proportion of the total variance in academic achievement may be attributed to academic resources, dual enrollment, parental education, persistence, and social interactions?

  8. Research Design/Methods A QUALquan mixed method design was used for the present study (Gay, Mills, Airsian, 2006). IRB Approval from both institutions, entry access granted, consent forms Qualitative :Phenomenological Approach via FG: - Group 1 :12/15 participants (9F -3M);60 minute session - Group 2: 9/14 participants (7F – 2M);75 minute session Quantitative - ID Target Population –Survey (11Q-60 Item): MLR - 86 surveys – 38.4% return rate

  9. Survey/CodingExample 1 What is your gender? A. Male B. Female Scaling level of the data above: Coded the data Male (0) and Female (1)

  10. Survey/Coding Example 2 Father’s level of education: Less than high school High school or GED Some college, including vocational/technical Bachelor’s Degree Graduate (Master’s or Doctorate) I do not know Code? Coded the data: a = 1, b = 2, c = 3, d = 4, e = 5

  11. Survey/Coding Example 3 How often do you visit with your professor outside the classroom? I do not visit Weekly Once a semester More than once a semester Code? Coded the data: a = 1 b = 4 c = 2 d = 3

  12. Pre-Analysis:Quantitative Distribution Graph Box-Whisker’s Plot Stem –Leaf Plots Exploratory/Measurement Analysis: - Master data Spreadsheet of Raw Data: Carefully SPSS-17 (5 constructs and 22 IV variables) - Descriptive Data - √ (N); min/max; Std. Dev.; Skewness; Kurtosis Shape –Kolmogorov N Test Linearity –Outliers Shape of the Distribution

  13. Pre-Analysis:Quantitative Distribution Graph HSRankskewness =+4.328 OutClassMskewness= -1.41 Skewness: Symmetry of the Distribution Alpha Error : And ? Variance is due to Regression Divide it by std. error

  14. Pre-Analysis:Quantitative Box-Whisker’s Plot 3 rd Quartile Linearity –Outliers Median Exploratory/Measurement Analysis: 1st Quartile

  15. Review your Descriptive Statistics Results Next Slide has steps for Descriptive Statistics Then Scroll through the SPSS results you obtained See next slide

  16. Steps for Descriptive Statistics SPSS – Highlight all the variables Go to Analyze Go to Descriptive Statistics Go to Descriptives Move the variables into “variable” slot and go to “options” Click on the choices (Mean, Std. Dev., Variance, etc) Results on the next slide

  17. Results of Descriptive Statistics Note: N for each column [excellent checkpoint] Note: Mean and Median Note Skewness [close to 0][Type I alpha error][+skewness mean is higher than median] [- skewness mean is lower than the median] Note Variance [Don’t want 0] Note: Kurtosis [- platy & + lepto]

  18. Steps for Explore SPSS – Highlight all the variables Go to Analyze Go to Descriptive Statistics Go to Explore Move ALL the variables into the dependent variable Click on Statistic Description 95% CI Click on Continue and go to Plots Click O’K to run the data Select stem/leaf; histogram, normal plot

  19. Results of Explore (Normality Test) Tests of Normality Kolmogorov-Smirnova Statistic df Sig. AcadAch.074 86 .200* a. Lilliefors Significance Correction *. This is a lower bound of the true significance.

  20. Psychometric Properties - Psychometric Properties of the IV: Item Analysis and Discriminatory Index : Socialization construct: inter-item correlation to make sure they were measuring the same phenomenon. One of the four socialization items was contributing to noise and lowering our Cronbach’s alpha reliability value (consistency). It was removed and the Cronbach alpha reliability level changed from .512 to .594

  21. Steps to Reliability First acquire reliability Cronbach’s alpha on 4 socialization variables Click on analyze Click on Scale Click on Reliability Move in (4) socialization variables For Model Click on Alpha

  22. Cronbach’s Alpha Reliability of 4 Socializ. Variables Reliability Statistics Cronbach's Alpha N of Items .512 4

  23. Step for Discrim. Index Now aggregate the 4 items under socialization into one composite or total score Go to Transform Compute variable Under target variable enter new name: “NewTotalSoc” Enter the (4) socialization variables and click O’K (XXX+XXX+XXX+XXX) Under the variable view, you should see the new variable name (NewTotalSocialization) Then go to Analyze*Correlate*Bivariate*enter the Newtotalsocial variable PLUS the other (4) social variables (how do the four items correlate with the total score?) Click the Pearson ( r) correlation coefficient and 2 tailed test Click O’K ---- See next slide

  24. Review your Psychometric Testing Results: Reliability Using the (4) socialization items and the new aggregate total score

  26. Review your Psychometric Testing Results: Reliability Now take the three significant socialization items and run the reliability test – see next slide

  27. Reliability Statistics Cronbach's Alpha N of Items .512 4 Cronbach’s Alpha Reliability of 3 Socializ. Variables Without Socialization with Counselor: Almost 60% of the variance is true or reliable Reliability Statistics Cronbach's Alpha N of Items .594 3

  28. Data Analysis Intercorrelation Matrix Bivariate Correlational Analysis Pearson (r ) Corr. Coef : High Correlation with the DV and little or no correlation among the other IV 11 of the 22 variables had a significant correlation with the DV (86 surveys X 60 items)

  29. Data Analysis Intercorrelation Matrix :Caution

  30. Steps for Bivariate Correlation Go to Analyze Correlate Bivariate Move in all variables (DV and IV) Select Pearson (r ) correlation coefficient Select 2 tailed test Click O’K to run the data

  31. Review your Correlation Results Correlation Coefficient

  32. Remember 11 of the 22 variables had a significant correlation with the DV (86 surveys X 60 items)

  33. Data Reduction Factor Analysis – a statistical method used to describe variability among observed variables Helped with data reduction - variables testing the same underlying phenomenon

  34. Steps for Factor Analysis Click on Analyze Dimension Reduction Factor Input 11 IVs and then go to Rotation Select Varimax Click O’K
