Nat'l Academies Pre-print Report on Discipline-Based Education Research

This 270 page "synthesis study" collects the literature and assesses research on approaches to undergraduate science education.  I haven't read the report, just skimmed the 19-page Executive Summary. 

Most reports by the National Academies can be read online for free, including this one.  From the Exec. Summ.:

DBER scholars have devoted considerable attention to effective instructional strategies and to students’ conceptual understanding, problem solving, and use of representations. Key findings from DBER are consistent with cognitive science research and studies in K-12 education.

To gain expertise in science and engineering, students must learn the knowledge, techniques, and standards of each field. However, across the disciplines, the committee found that students have incorrect understandings about fundamental concepts, particularly those that involve very large or very small temporal and spatial scales. Moreover, as novices in a domain, students are challenged by important aspects of the domain that can seem easy or obvious to experts, such as problem solving and understanding domain-specific representations like graphs,
models, and simulations. These challenges pose serious impediments to learning.

DBER clearly shows that research-based instructional strategies are more effective than traditional lecture in improving conceptual knowledge and attitudes about learning. Effective instruction involves a range of approaches, including making lectures more interactive, having students work in groups, and incorporating authentic problems and activities.

To enhance DBER’s contributions to the understanding of undergraduate science and engineering education, the committee recommended:

• Research that explores similarities and differences among different student
  populations.
• Longitudinal studies—including studies of the K-12/undergraduate transition— to better understand the acquisition of important concepts and factors influencing retention.
• More studies that measure outcomes other than test scores and course performance, and better instruments to measure these outcomes.
•  Interdisciplinary studies of cross-cutting concepts and cognitive processes.

Another blog

I really enjoy Olivia Judson's blog posts for the New York Times. She's an evolutionary biologist at Imperial College in London, and she's witty, imaginative and seems really smart. Today's post discusses the bacteria discovered in rocks deep below the seafloor, and the possibility that they may contribute to weathering of the crust. She has blogged about ichnofossils, rain-seeding bacteria, and what the world would be like if all genetic mutation stopped. She is given to flights of fancy, like this one on dinosaur mating habits:

"Which brings me to my tyrannical fantasy. I want to take a journey 68 million years back in time to see a Tyrannosaurus rex couple mating. What was it like? Did they trumpet and bellow and stamp their feet? Did they thrash their enormous tails? Did he bite her neck in rapture and exude a musky scent? Somehow, I imagine that when two T. rex got it on, the earth shook for miles around."

Or this one on things that live among pineapple leaves:

"The other day, I went to the supermarket to buy a pineapple. I didn’t select the one that smelled the ripest, but the one with the most impressive leaves: tall, bushy and uncrushed by the journey from Costa Rica. When I got it home, I put it in the kitchen sink, turned on the tap, and watched how the water gathered and formed pools in the spaces between the leaves. And I began to imagine that I was not a human in an apartment in London, but a small frog in a tropical forest, climbing up the leaves of a plant like a pineapple, looking for a pool where I could deposit the tadpole I’m carrying on my back."

Her curiosity as an evolutionary biologist leads her to think about a range of environments, from clouds to the "deep subsurface biosphere." As a geologist, I find lots to think about in her articles. Take a look at a couple yourself. They make for provocative reading, but they're somehow relaxing.
