NW Biology instructors Conference 2017
Power Score Assessment for Biology Majors
NORTH SEATTLE COLLEGE
Brian Saunders, Hugo Alamillo, Katie Barndt
VISION – To assess student learning and concept retention of Biology majors
MAIN GOAL– To develop a tool that best assesses student learning and understanding in the Biology major series (Biol 211, 212, 213) and identify how well students retain and apply knowledge to advanced courses
Photos should be at least 300dpi, but not more than 5-12 mgs each. Your poster is set to be enlarged 200% so do not change the page size to fit another poster size. Posters (3’ x 4’) will be printed at WWU using the same purchase order at the same time. Please your poster as a PPT file to by Joann Otto at WWU by Wednesday, April 21, 2017, by 5 pm. Please contact Joann Otto with questions about poster printing. Also please put your institution “logo” on your poster.
Please note that this template is provided to simplify your effort to prepare a poster for the NW Biology meeting. You can change the font size, colors, column widths, add photos, institutional logos, graphics, etc. This template can also be used as a starting point and you can be as creative as you want in your poster. However, we would like to have all of the posters the same size and we will be printed at the same time, at the same print shop in order to easily pay for printing with one purchase order.
ACTIONS
BARRIERS & CHALLENGES
Products / Reflections / …
Development of Power Score Assessment.
Design diagnostic questions where answers can assess level of student understanding
Answers are ‘ranked’ quantitatively which calculates a student Power Score
Power scores are statistically analyzed between different biology cohorts
Developing solid diagnostic questions.
Variability of Instructor teaching methods makes it difficult to identify ‘best practices’ for instruction
Section sizes of Biology series are not equal
Heterogeneity of student background
Reflection of Diagnostic Questions using Power Scoring (PS)
Why do cells perform cellular respiration?
To produce oxygen (PS = 0.0)
To supply cells with carbon (PS = 0.33)
To gain energy from food molecules (PS = 0.66)
To produce ATP from food energy (PS = 1.0)
SUSTAINABILITY
STRENGTHS & LEVERAGE
RESOURCES & ALLIES
Initial study acts as a baseline for future analysis
Strong statistical assessment.
Identifies topics students have greatest difficulty understanding / retaining for advanced courses
Strong Biology Instructor pool
Can be used as Program Review and accreditation evaluation
Strong support from Administration
Could be used to assess active learning (AL) teaching strategies more accurately
Low cost
UNINTENDED CONSEQUENCES?
Pre-Biology students showed strong initial Power Scores (see Figure 1)
Assessment of Bio 212 students may reflect summer quarter bias
FUTURE GOALS
We hope to use the Power Score assessment to re-evaluate student learning using more active, inquiry-based teaching strategies
