Founded in 1855, the university has a stated threefold mission of teaching, research, and public service. Its instructional mission includes undergraduate, graduate, professional and continuing education offered through resident instruction and online delivery. Its University Park campus, the flagship campus, lies within the Borough of State College and College Township.
The Penn State Dickinson School of Law has facilities located in both Carlisle and State College and the College of Medicine is located in Hershey. Penn State has another 19 commonwealth campuses and 5 special-mission campuses located across the state. Penn State has been labeled one of the “Public Ivies,” a publicly funded university considered as providing a quality of education comparable to those of the Ivy League.
Annual enrollment at the University Park campus totals more than 45,000 graduate and undergraduate students, making it one of the largest universities in the United States. It has the world’s largest dues-paying alumni association. The university’s total enrollment in 2009–10 was approximately 94,300 across its 24 campuses and online through its World Campus.
The university offers more than 160 majors among all its campuses and administers $1.83 billion (as of June 30, 2011) in endowment and similar funds. The university’s research expenditures exceeded $753 million for the 2009 fiscal year and was ranked 9th among U.S. universities in research income by the National Science Foundation.
Given the difficult-to-digest subject matter in many STEM classrooms, educators have customarily relied on traditional lecture-based educational methods where they spend class time walking through content and then assign homework problems to supplement that learning.
Liberal arts classrooms, on the other hand, often invert that structure. They task students with learning the material from a book outside the classroom and then turn class time into active discussion periods where they expand and develop what they’ve read.
“It’s difficult for an engineering student to extract the technical information from a book on their own,” said Stephanie Butler Velegol, instructor in environmental engineering. “Students need to hear the problem-solving out loud; they need to hear the way the professor works through the solution to the problem.”
The issue with the traditional lecture-based approach in STEM education is that even with capable and committed faculty, the method just doesn’t engage some students and keep them interested. Even when it is successful, educators find they have a hard time interacting with students when they’re constantly behind the lectern.
That’s where the flipped classroom comes in. In a flipped classroom, students gain technical knowledge through online videos that prepare them to participate in in-class activities, which may include problem-solving, discussions, brainstorming, design work, guest speakers, or field trips.
A lithium-ion battery that self heats if the temperature is below 32 degrees Fahrenheit has multiple applications, but may have the most impact on relieving winter “range anxiety” for electric vehicle owners, according to a team of researchers from Penn State and EC Power, State College.
“It is a long standing problem that batteries do not perform well at subzero temperatures,” said Chao-Yang Wang, William E. Diefenderfer Chair of mechanical engineering, professor of chemical engineering and professor of materials science and engineering and director, Electrochemical Engine Center. “This may not be an issue for phones and laptops, but is a huge barrier for electric vehicles, drones, outdoor robots and space applications.”
Conventional batteries at below freezing temperatures suffer severe power loss, which leads to slow charging in cold weather, restricted regenerative breaking and reduction of vehicle cruise range by as much as 40 percent, the researchers said in today’s (Jan. 20) issue of Nature. These problems require larger and more expensive battery packs to compensate for the cold sapping of energy.
