  17. How To Assess Laboratory Learning Goals? • 3 methods

  18. How We Assess Laboratory Learning Goals • Assess Lab Notebooks • Assess Lab Reports • Practica • Exams • Regular Observations of Lab Performance • Oral vs. Written Communication • Pre and Post Test

  19. Example: MWSU Skills Survey Use the following scale, circling the appropriate statement that best matches your feeling about the following laboratory related questions. Strongly Somewhat Neutral/ Somewhat Strongly Disagree Disagree No Opinion Agree Agree 1 2 3 4 5 1. I am able to solve basic mathematic problems that require scientific notation or exponents. 1 2 3 4 5 3. I can accurately determine the correct number of significant digits in a number. 1 2 3 4 5 79. Complete the following mathematical equation, and give your answer with the proper number of significant digits. a. 4.0 x 105 b. 4.00 x 105 c. 4.00367 x 105 d. 400,367

  20. Lab Task Questions (% Correct) Neutral/ No Opinion Somewhat Agree Somewhat Disagree Sample of pre-course survey at (Spring 2010 results). Strongly Agree Strongly Disagree Sample survey questions & responses (%) are shown (grey) Results of task related questions (Far right , yellow) displays overall class performance (% correct).

  21. Final Exam Results Scores represent percentage of students receiving full credit for each question. • However, some areas still requiring improvement (indicated by yellow) include: • Interpreting graphic data (Q’s 2, 6, 9) – graphical/SDS-PAGE results • Comprehension of enzyme assays and kinetics (Q’s 5, 9) • Performing biochemical calculations (Q’s 7, 9)
