Education reform expert to offer 'Finnish Lessons,' Nov. 8

October 15, 2012

Pasi Sahlberg, known for his work on K-12 education policy and reform in Finland, will speak at 5:30 p.m., Nov. 8, in the Pima Room (room 230) of the Memorial Union building on ASU’s Tempe campus. Doors open at 5 p.m.

The event is free and open to the public. Parking is available for a fee in the Apache Blvd. parking structure. Members of the public interested in attending the lecture may R.S.V.P. via Pasi Sahlberg Download Full Image

In his presentation Sahlberg will touch on multiple issues relating to Finland’s phenomenal success in K-12 education as seen in the international PISA (Programme for International Student Assessment) results. He will talk, in particular, about the “road Finland has traveled to get there” over the past 30 years – including the larger societal issues, education policies, implementation challenges, the egalitarian role of women and men in shaping education policy, societal appreciation of teachers, as well as classroom teaching and learning.

Sahlberg’s notable books include “Finnish Lessons: What Can the World Learn from Education Reform in Finland,” “The Fourth Way of Finland,” “Rethinking accountability in a knowledge society,” “Creativity and innovation through lifelong learning,” and “Education Reform for Raising Economic Competitiveness.”

The event is presented by the Mary Lou Fulton Teachers College at ASU, and co-sponsored by William G. Jackson, Alfredo J. Molina, RW Partners, Cheryl and Duane Rodgers, Hannele and Gary Waissi for the Honorary Consulate Finland to Arizona and New Mexico, the Arizona Science Education Collaborative (ASEC), the Consulate General of Finland – Los Angeles and FINNFEST USA.

Sahlberg has published more than 100 articles, chapters and books primarily on education reform, education policy, lifelong learning, and their relationship to economic competitiveness. He serves currently as the Director General of the Center for International Mobility (CIMO) in Helsinki, Finland. He received his doctorate in Educational Sciences from the University of Jyvaskyla, Finland.

3-D technology boosts project to aid heart surgery

October 15, 2012

Efforts to improve preparation for heart surgery are the focus of a collaboration of Arizona State University biomedical engineering researchers and physicians at Phoenix Children’s Hospital and St. Joseph’s Hospital and Medical Center in Phoenix.

Surgeons at these medical facilities are using three-dimensional physical models of hearts developed by an ASU team led by David Frakes, an assistant professor in the School of Biological and Health Systems Engineering and the School of Electrical, Computer and Energy Engineering, two of ASU’s Ira A. Fulton Schools of Engineering. 3-D heart models Download Full Image

The heart models are constructed using information acquired from computed tomography (CT) scans and magnetic resonance imaging as a design blueprint. 

The custom-made models reveal a wealth of information about a patient’s heart condition, providing physicians with a tool to aid surgical planning with the aim of decreasing the likelihood of complications during surgery.

The project has recently been aided by the acquisition of a three-dimensional printer with the support of a $75,000 grant from Phoenix Children’s Hospital Leadership Circle awarded to Stephen Pophal, director of the Children’s Heart Center for Pediatric Cardiology.

The Leadership Circle is a group of more than 100 community leaders who help raise funding for research initiatives and new technologies for the hospital.

Use of the new printer significantly improves the manner in which a three-dimensional heart structure is communicated to surgeons, giving them a quick, accurate and intuitive understanding of a patient’s anatomical condition.

“This knowledge means patients can spend a lot less time in surgery and under anesthesia, which could greatly reduce the risks of these invasive procedures,” explains Frakes, who is also working to develop use of the models as educational tools.

Justin Ryan, a biomedical engineering doctoral student on Frakes’ research team, describes the three-dimensional printing technique as similar to constructing a building out of bricks. “Many layers of bricks, laid from the ground up, create a building – a full three-dimensional object,” he says. “The heart models are essentially printed one brick at a time in layers, until the model is whole.”

The new printer at Phoenix Children’s Hospital produces three-dimensional heart models by first printing extremely thin two-dimensional slices, which are then bound together by an adhesive and sprayed with ink to give the model various colors that denote specific anatomical features. An average heart model printout consists of around 600 bound layers, each only about one-tenth of a millimeter thick.

At ASU, doctoral student Fariha Ejaz and Megan Henrikson, who recently earned a master’s degree, have contributed extensively to concept development and production of the heart models. Undergraduate Lillee Stomski has participated in three-dimensional modeling work.

New team member Rachel Austin, a master’s degree student in biomedical engineering, is now working with Ryan and Frakes to explore applications of three-dimensional heart modeling and three-dimensional printing for improving artificial heart implantation.
