CUREs for the research blues

Four reasons to say YES to a class with built-in research experience

"We're going into the unknown together." 

That's what geology professor John Bershaw told his Sedimentology and Stratigraphy class as they dove into a different type of lab course. Split into groups, the class of 15 undergraduate students spent several weeks analyzing and correlating water well logs against rock data they collected during a multi-night field trip at Lake Billy Chinook Reservoir outside Madras. He didn't know what connections or conclusions they'd draw, but that's the beauty of research. 

"We're going to look into something and see what we find and deal with all the pain and joy that comes with that process," he said.

That process of discovery and iteration is what makes course-based undergraduate research experiences, or CUREs, different from traditional lab courses with predetermined outcomes. The goal is to make research opportunities more accessible to more students — and more of these types of courses will be offered in the coming terms at Portland State as a group of faculty continue designing and developing a variety of CUREs across different disciplines.

Here are four reasons why you should take a CURE:

1. You want a research experience but you don't have time outside of class.

Course-based undergraduate research experiences are just that — research experiences embedded into your regular courses. They involve everyone in your class collectively addressing a research question or problem that is of interest to the scientific community — and sometimes beyond.

If you don't have the time or can't afford to volunteer in a professor's research lab, you can still experience what it's like to do real research. Plus, professors have limited student positions in their labs so even if you approached a professor about an opportunity, they might not be able to take you on.

"Anybody who has an opportunity to do a real research project and do it as part of your homework, it's the coolest learning experience and it's a good challenge," said Melissa Palmer, a post baccalaureate geology student who took Bershaw's Sedimentology and Stratigraphy class.

2. You want to do authentic and original research.

It might be a little unsettling when your professor doesn't even know what the outcome of a project will be, but that's part of their everyday life as a researcher — and CUREs give you a taste of that discovery process.

Bershaw said he was straightforward with his class: he didn't know the answer, he didn't know what they were going to find and there were a lot of ways it could turn out.

Palmer said she liked the autonomy they had to explore the data. 

"As a group, we were assigned a well log, but all five of us went in different directions in how we digested the data, what we chose to draw from it to make suggestions or conclusions," she said. "We thought of ways to tie our findings back to the watershed to see if we could offer advice for how water could be more equitably shared, distributed or conserved."

Though the class' conclusions weren't necessarily groundbreaking, their work does provide new insights about the aquifers in central Oregon that could prove useful to both farmers and regulators.

"This is new information we're gathering," Bershaw said. "This is a water-stressed area and there are water rights issues that can be contentious. Depending on the nature of these aquifers, one farmer's well usage can affect another well."

Even if Bershaw repeats the same project, it's unlikely to look the same from year to year as questions and answers evolve with each new class.

In some CUREs, the work done in the classroom directly relates to your professor's research program. You might be helping them scale up or pursue a new research direction or collect enough preliminary data for a project to apply for a larger grant. 

3. You want (or know you need) to get comfortable with uncertainty.

Uncertainty is a part of science — and taking a CURE can teach you the value of failure (which isn't a bad thing!)

"Experiments fail, populations die off, reagents don't work, instrumentation breaks," said Erin Shortlidge, a biology professor whose research aims to better understand best practices in teaching and learning in biology and other science fields. "There's an infinite number of ways science can go wrong, but you inevitably learn something from that experience."

Shortlidge said that through scientific trial and error, students can learn to think like a scientist through working your way around a problem, being flexible, making connections with things that might have seemed previously unconnected, and troubleshooting in real time.

"Doing research can involve developing a certain amount of comfort with uncertainty and unpredictability," she said. "It's a great skill to hone while you  work with peers on something that matters."

4. You want to bolster your grad school or job application resume. 

If you have your sights set on grad school, med school or professional school, chances are an undergrad research experience is going to help give you an edge. Even if you decide not to pursue research as a career, the skills you'll learn — discovery, creative problem solving, collaboration — will make you attractive to future employers.

Recent CUREs:

Chem + Bio CURE (BI 410 or CH 410)
You will investigate the microbial community in Pacific Northwest fungi. Specifically, you will discover the diversity and secondary compound chemistry in fungus-associated microbes. This is cutting edge research – there is not even a scientific term describing these microbial symbionts yet! In this class you will have an opportunity to: 1) use a natural fungus/microbe system to characterize molecular diversity using PCR and sequencing, 2) analyze microbial chemical profiles, 3) test for bioactivity of microbial compounds using different types of bioassays, and 4) learn how to analyze, interpret and present molecular and chemical data. Ultimate goal is to prepare a manuscript or parts of a manuscript suitable for submission to a scientific journal...depending on your findings! Suggested preparation: CH 339 or BI 336, 337. Instructor approval required.
