Computational Complexity The Burden of Large CS Enrollments

The Computational Complexity blog recently posted a piece on The Burden of Large Enrollments in CS departments. It seems that this trend is global but interestingly they point out that if you average out the growth over the booms and bust in CS enrolment since they 1970s, the growth rate is a steady 10%. 
Thanks to my colleague Mark for bringing this to my attention.

Announcing the Google CS Engagement Small Awards Program

Posted by Leslie Yeh Johnson, University Relations

(cross-posted on the Google for Education blog)

College students are more interested than ever in studying computer science. There has been an unprecedented increase in enrollment in Computer Science undergraduate programs over the past six years. Harvard University’s popular introductory CS course CS50 has recently claimed the spot as the most enrolled course on campus. An astounding 50% of Harvey Mudd’s graduates received engineering degrees this year. However, while the overall number of students in introductory computer science courses continue to climb, the number of students who go on to complete undergraduate degrees in this field, particularly among women and under-represented minorities, does not match this increase in individual course enrollment (2013 Taulbee Survey).

Recent findings show that while students may begin a CS degree program, retaining students after their first year remains an issue. Research indicates that one of the strongest factors in the retention of students in undergraduate CS degrees is early exposure to engaging courses and course material, such as high quality assignments that are meaningful and relevant to the student’s life or classroom activities that encourage student-to-student interaction. When an instructor or department imbeds these practices into the introductory CS classroom, students remain excited about CS and are more likely to complete their undergraduate CS degree.

At Google we believe in the importance of preparing the next generation of computer scientists. To this end, we’ve created the CS Engagement Small Grants Program to support educators teaching introductory computer science courses in reaching their engagement and retention goals. We’ll give unrestricted gifts of $5,000 to the selected applicants’ universities, towards the execution of engaging CS1 or CS2 courses in the 2014-2015 school year. We encourage educators who are teaching CS1 and CS2 courses at the post-secondary level to apply to the Google CS Engagement Small Grants Program. Applications will be accepted through November 15, 2014 and will be evaluated on an ongoing basis. If you’re interested in applying, please check out the Call for Proposals.

The Thorny Issue of CS Teacher Certification

Posted by Chris Stephenson, Head of Computer Science Education Programs

(Cross-posted on the Google for Education Blog)

There is a tremendous focus on computer science education in K-12. Educators, policy makers, the non-profit sector and industry are sharing a common message about the benefits of computer science knowledge and the opportunities it provides. In this wider effort to improve access to computer science education, one of the challenges we face is how to ensure that there is a pipeline of computer science teachers to meet the growing demand for this expertise in schools.

In 2013 the Computer Science Teachers Association (CSTA) released Bugs in the System: Computer Science Teacher Certification in the U.S. Based on 18 months of intensive Google-funded research, this report characterized the current state of teacher certification as being rife with “bugs in the system” that prevent it from functioning as intended. Examples of current challenges included states where someone with no knowledge of computer science can teach it, states where the requirements for teacher certification are impossible to meet, and states where certification administrators are confused about what computer science is. The report also demonstrated that this is actually a circular problem - States are hesitant to require certification when they have no programs to train the teachers, and teacher training programs are hesitant to create programs for which there is no clear certification pathway.

Addressing the issues with the current teacher preparation and certification system is a complex challenge and it requires the commitment of the entire computer science community. Fortunately, some of this work is already underway. CSTA’s report provides a set of recommendations aimed at addressing these issues. Educators, advocates, and policymakers are also beginning to examine their systems and how to reform them.

Google is also exploring how we might help. We convened a group of teacher preparation faculty, researchers, and administrators from across the country to brainstorm how we might work with teacher preparation programs to support the inclusion of computational thinking into teacher preparation programs. As a result of this meeting, Dr. Aman Yadav, Professor of Educational Psychology and Educational Technology at Michigan State University, is now working on two research articles aimed at helping teacher preparation program leaders better understand what computational thinking is, and how it supports learning across multiple disciplines.

Google will also be launching a new online course called Computational Thinking for Educators. In this free course, educators working with students between the ages of 13 and 18 will learn how incorporating computational thinking can enhance and enrich learning in diverse academic disciplines and can help boost students’ confidence when dealing with ambiguous, complex or open-ended problems. The course will run from July 15 to September 30, 2015.

These kind of community partnerships are one way that Google can contribute to practitioner-centered solutions and help further the computer science education community’s efforts to help everyone understand that computer science is a deeply important academic discipline that deserves a place in the K-12 canon and well-prepared teachers to share this knowledge with students.
