Evaluation of 4-H and FFA Members Scores on the 2011-2012 Texas Quality Counts Verification Exam
Experimental results indicated that dolomite dissolution rates increased in all the acid solutions as the disk rotational speeds increased at 150, 200, and 250?F. The dissolution of dolomite in 0.886 M GLDA was found to be surface-reaction limited at lower temperatures and mass-transfer limited at highest temperature. GLDA with the lowest reaction rates and relative diffusion coefficient demonstrated retardation before spending with deeper penetration capability for productivity and injectivity improvement.
The purpose of this study was to analyze the Texas Quality Counts Verification Exam for junior and senior aged 4-H and FFA members. The Texas Quality Counts program was developed due to a need for teaching livestock ethics and care to the youth of Texas and it strives to teach youth how to produce a safe and wholesome livestock product for the consumer.
An analysis of youth scores between 2011 and 2012 was done to determine how well youth were scoring on the Texas Quality Counts Verification Exam. Out of the 91,733 attempts, 18,204 were taken by juniors and 73,572 were taken by seniors. Junior level attempts show a fairly even spread among self-identified membership in 4-H and FFA, while senior level attempts saw a much greater spread in membership, with 73% of attempts taken by youth who identified themselves as a member in FFA. Overall, 78% of junior level youth were able to pass the exam on their first attempt, and showed a range of mean attempts between 1.13 and 1.47 based on age. Senior level youth, on the other hand, had only 47% pass on their first attempt and had a range of mean attempts between 2.21 and 2.54 based on age. The means of scores on the exam were calculated for juniors and seniors, with 0.85 and 0.71 respectively. To determine if there were any differences in scores between self-identified membership in 4-H, FFA, or both 4-H and FFA, a oneway ANOVA for junior and senior members was conducted. Both junior and senior age groups showed a significant difference between the three membership categories (p=0.001).
