Meet the Key. PURs Key Points & Useful Repetition

The Problem l l l Content heavy curriculum and no where to cut Retaining basic facts over the course of the semester Retaining basic facts for professional practice

Solution l l l Meet the Key. PURS Series of foundational blocks of information Points awarded weekly l l New information Repeat information

Explanation to students l l l Useful repetition NOT busy work Points awarded for correct answers Manipulative created for professional practice Challenge 100% correct response on specific Key. PUR exam questions Ready, set, go!

Format l Chart format l l Pathogen Environment Gram stain morphology Additional information (no more than 3)

Week 1 Meet the Key. PURS (fill in the blank challenge for week 1) Week Organism 1 Staphylococcus aureus Environment Gram stain morphology Additional information

Week 4 Answers Week Organism Environment Gram stain morphology Additional Info. 1 Staphylococcus aerobe aureus Gram + cocci s/pr/cl Catalase + Coagulase + 2 Streptococcus pyogenes aerobe Gram + cocci s/pr/ch Catalase= PYR+ BSA 3 Enterococcus species aerobe Gram + cocci s/pr/ch Catalase= Hydrolyzes BE PYR+ 4 E. coli aerobe Gram = bacilli Oxidase= Indole+

And so on…. . weeks 5, 6, 7, 8, 9 l l Building new information on top of the old New weekly information often corresponded with lecture material and laboratory experience 2 points for each correct line (all information had to be correct to receive credit for that line) Continues through week 10

Finally reaching week 10

And Beyond… l Student comments from Professional Practice: l l l “My Key. PURs are a life saver” “I use my Key. PURs everyday in micro” “Review your Key. PURs, they really do help” “I LOVE Microbiology and the Key. PURs really helped me” “Micro ROCKS (with a little help from my Key. PURs)!!!!!!”

Clinical Faculty Comments l l “Student” seemed more comfortable with common pathogen information “Student” was well prepared on a daily basis (nice change from previous years ) l “What a joy to teach micro when the student actually knows a little about the pathogens”Good job with those cards!

Conclusion l l Basic key foundational material can be reinforced through useful repetition Students engage once they realize the value of the information Information can be retained beyond the semester’s end Information can be formatted for students to use as an immediate resource
