  • Transition From Breadth to Depth Are you concerned whether your students will be prepared for college-level science? Gonzagas new integrative curriculum Authentic research laboratory experience Student responses to this experience
  • Slide 8
  • Gonzagas Authentic Research Experience Transforming the Undergraduate Biology Laboratory Experience: What is an Authentic Research Experience? What do we study at Gonzaga? What do students need to know to succeed?
  • Slide 9
  • Gonzagas Authentic Research Experience What is an Authentic Research Experience? Engaged in real science problems 1, 2 The problems have no known solution1,2 Students interact with peers and other scientists1,2 Experienced mentors model problem solving1,2 The tools, skills, and practices are current and real1,2 High potential for presentation and/or publication2 1.Laursen, S; A Hunter; E Seymour; H Thiry; G Melton. 2010.

  • Gonzagas Authentic Research Experience Gonzaga students study bateriophages. Bacteriophages (aka phages) are viruses that infect bacteria. Phage Arthur, 2014 All Introductory Biology Students (freshmen) are immersed in a real research program that continues for those in the major.

  • Gonzagas Authentic Research Experience Phage Discovery Lab Collect Purify Characterize o Plaque formation o Virus morphology o Genome
  • Slide 12
  • Gonzagas Authentic Research Experience Sophomore Genomics: Two Phage Modules Select phage genomes from the Phage Discovery Lab are sent for sequencing Bacteriophage genome annotation, with students submitting final annotation to GenBank Structural and evolutionary genome analysis Phage Genomics Genetic Analysis of Phage Diversity Each student clones a fragment of his or her phage Cloned fragments are sent for sequencing Relationships with known phages determined from public databases (BLASTn, PhagesDB.org)
  • Slide 13
  • Gonzagas Authentic Research Experience Junior or Senior Advanced Phage Research Phages of different subclusters are isolated at 37 C and 25 C Figure 1. Subcluster distribution of phages. Phages were isolated from soil around the Gonzaga campus in Spokane, WA in September 2011/2012 and in January 2013. Of 18 phages isolated at 37 C, 6 were of subcluster A3; 1 of A10; 1 of C1; 2 of E; 6 of F1; 1 of G; 1 of K4. Of 23 phages isolated at room temperature, 3 were of subcluster A1; 1 of A2, 1 of A6; 1 of A8; 2 of A9; 1 of G; 14 of K1. Subclusters of phages isolated at 37CSubclusters of phages isolated at 25C

  • Gonzagas Authentic Research Experience What skills do we think help students succeed in college research? Motivation Quantitative skills Communication (written and verbal) Group work
  • Slide 15
  • Gonzagas Authentic Research Experience What skills do we think help students succeed in college research? Quantitative Skills How big is my phage? If Arthurs tail measures 4.8 cm on my screen and the100 nm scale bar measures 1.3 cm, how long is Arthurs tail in nanometers? Phage Arthur, 2014 And see also: High School math classes are the only cross- discipline predictor of success in college science classes (Sadler and Tai, 2007).

  • Transition From Breadth to Depth Are you concerned whether your students will be prepared for college-level science? Gonzagas new integrative curriculum Authentic research laboratory experience Student responses to this experience
  • Slide 17
  • Student Responses What did students gain from the authentic research experience? What are the important components that allow for these student gains?
  • Slide 18
  • What did our students gain? Similar to previous observations (Seymour et al 2005) Thinking and working like a scientist Increased interest and/or decisions about career/major Skills, basic knowledge (skip; not unique) Increased confidence
  • Slide 19
  • What did our students gain? Thinking and working like a scientist: Making connections Question: What was your favorite ah-ha moment?* I didn't have just one ah-ha moment, but rather felt that I was understanding the process and why I was doing what I was doing as the weeks progressed. I started out not entirely understanding the reasoning behind the steps we were taking. After a couple weeks everything started coming together. From that point on, I was sometimes confused, but my overall understanding continued to grow, which made me much more interested in the material. -Spring2014 Quote #39
  • Slide 20
  • What did our students gain? Thinking and working like a scientist: Repeating/dealing with failure Question: What was your favorite ah-ha moment?* I found that after having to do the DNA extraction a second time, I became more familiar with the process that we were doing in the experiment and it made more sense as to why we were doing each step. -Spring 2014 Quote #100
  • Slide 21
  • What did our students gain? Thinking and working like a scientist: Ownership Question: What was your favorite ah-ha moment?* For me, receiving the TEM images was extremely reassuring. That was the moment that I realized that I was actually producing tangible, real results. -Fall 2013 Quote #57
  • Slide 22
  • What did our students gain? Thinking and working like a scientist: Science as a process: How is knowledge created in science? Question: Give an example of how has this lab impacted your understanding of science? by giving me an insight into the amount of time it takes to get the information that we read in our science books. It helped me to really see that science is a process and that results do not occur over night. -Fall 2013 Quote#347
  • Slide 23
  • What did our students gain? Increased interest in major or informing their decisions about career Question: Give an example of how has this lab influenced your specific educational or career goals? because it has me excited to go out and do more research before i go into medical school. This class was a blast and now i know how much i enjoy research. -Fall2013 Quote#506 it made me realize how much i don't find research interesting -Spring2014 Quote#578
  • Slide 24
  • What did our students gain? Increased confidence The culture of applying to med-school is highly competitive, and there is a lot of emphasis on not messing up. I think this is very unhealthy, and only promotes a false sense of self-confidence; but it's okay to make mistakes -- it's how we learn (or at least how I learn best). Because of this, I no longer have any fears of messing up, and I'm okay with that. -Spring2014 Quote#614 I definitely feel much more confident going into other labs now and I am not so afraid of learning how to use unfimiliar techonology in a lab setting. -Spring2014 Quote#617
  • Slide 25
  • What did students gain from our authentic research experience? Thinking/working like a scientist Experience science as a process Ownership Informs career/major, increase interest Increased confidence
  • Slide 26
  • What are the important components for an authentic research experience?
  • Slide 27
  • Important Components Multi-week project that allows time for: Student learning Repeating procedures Summative assignments (poster, presentation, exam/midterm) Authentic research skills that transfer to career: Micropipetting Aseptic technique Lab notebook Group work
  • Slide 28
  • Colleges - more integrative approach with less subject-specific material Successful students strong quantitative, communication, and interpersonal skills Early authentic research experiences for undergraduates Students gain understanding the nature of science, confidence, interest, ownership Conclusions
