Using MOOCs to Create a Flipped Classroom

Universities, community colleges, and high schools can use MOOCs to create an environment to enhance student learning.  Last fall a professor at San Jose State used recorded MOOC lectures in an introductory electrical engineering course to create a flipped classroom.  Students passed at a much higher rate than usual—91%, compared with 59% and 55% in two other, more traditional sections of the s

Bring the Educational System into This Century

Tammy Erickson states that our current approach to education was designed for a different age. It was modeled on the needs of industrialization, resulting in separate subjects, standardized curricula, conformity, and batch processing. The model worked well for 100 years because it satisfied the needs of employers. However, the needs of employers have change and the gap between the output of our educational system and the job demands of the current century is big. Traditional schools operate in ways that are foreign to the world in which students live. The students inhabit a technology-based world of multimedia, addictive games, and mobile access. They are living in the most stimulating period in the history of the earth. But then schools require them to put that all away and ask them to focus on one, often-not-that-engaging speaker. It is not surprising that students get distracted and are diagnosed with attention deficit disorder. A change the educational system is desperately needed.

Technology in College Teaching

Pamela Hieronymi wrote an interesting commentary about the increased need for teachers in the “tsunami” of technology. She readily admits that technology can enhance education and is here to stay. The plethora of technology options will force teachers to reflect on their role in the classroom and to become more effective. Hieronymi aptly describes teachers as “personal trainers in intellectual fitness”. The personal training and individual guidance becomes more necessary, not less, as the information options increase.

Consumatory Scholarship

Bruce Henderson in The Chronicle of Higher Education calls faculty to be more proactive in defining their contributions to educational institutions. In this time of cuts to education, university and secondary school faculty must help the general public understand the nature of their contributions.

Demographics of MOOC Students

MOOCs, massive open online courses, are gaining credibility. Two organizations offering MOOCs are Coursera and Udacity. These organizations have been fielding demographic surveys to better understand the background of the enrolled students and why they chose to take the MOOC courses. An article by Steve Kolowich in Inside Higher Education summarizes some of the survey data. One pertinent finding was that the majority of the enrolled MOOC students reside outside of the United States.

The Artificial Leaf: Daniel Nocera's vision for sustainable energy

MIT’s Dan Nocera (soon to be Harvard’s) gave a seminar in our department about a year and a half ago, and I heard him speak again in ACS President Bassam Shakhashiri’s ”Presidential Symposium on Catalysis” at the Spring national meeting in San Diego. The chemistry he described is a beautiful example of how fundamental research can potentially impact the lives of billions of people. Dan and his research group have discovered what appears to be an inexpensive, self-healing, air-tolerant catalytic system to split water into hydrogen and oxygen. We have seen before grand announcements about photocatalytic water-splitting systems, but this one appears not to suffer the fatal flaws of the others – requirement of pure water, expensive ingredients, and short duty cycles.

The Climate Fixers

Suppose that the earth’s atmosphere continues to warm, beyond the levels that we know are already inevitable.  Suppose that the arctic permafrost melts, releasing millions of tons of methane, which is about thirty times more effective at warming than is carbon dioxide, as well as much CO2 as is already in the atmosphere. Within a few years, the mean temperature rises by five degrees Celsius or more, sea levels rise, crops fail and millions starve.
