Dr. Khasawneh uses the flipped-classroom concept for teaching Statics, and parts of Dynamics, to civil and mechanical engineering sophomores at SUNY Polytechnic Institute. In this model, the instructor creates and shares course material typically in the form of recorded lectures outside of class. The students watch the lectures, take notes, and practice the basic concepts before coming to class. Class time is then used to discuss and apply the learned concepts. This contrasts the traditional classroom model where the instructor prepares class material and delivers it in class where students listen and take notes. The material in the traditional model is mostly applied after and outside of class in the form of assigned homework.
During class, the students are randomly split into teams of 3 or 4 and they are asked to sit next to their teammates. The class is then given a worksheet which normally includes 3 or 4 problems related the topics that the students watched in the videos and they are asked to work through it in teams.
This scenario creates concentric levels of learning where the individual is the center of the first circle, the group represents the second level, and third level is the other groups and the class as a whole. When students have a question about the worksheet, they are asked to go through these circles from the innermost to the outermost. Specifically, if a student within a group has a question then this question must be discussed within the group first. It is my observation that Group discussions resolve 75%-80% of the emerging questions. If the group cannot agree on an answer, then they flag down the instructor and pose the question as a group. When the question is resolved this way, it is often shared with the rest of the class in one of two ways: either the instructor stops the other groups to discuss and share the question, or the group that came up with the question becomes in charge of answering the same question if another group poses the same question. This way, knowledge propagates inwards and outwards in the concentric learning model.
Working in groups
fosters active and collaborative learning, which was recognized as one of the high-impact educational practices
and was identified by The National Survey on Student Engagement (NSSE)
as an important part of effective educational practices in the 2009 National Survey of Student Engagement.
This report explains,
“Students learn more when they are intensely involved
in their education and have opportunities to think
about and apply what they are learning in different
settings. And when students collaborate with others to
solve problems or master difficult material, they
acquire valuable skills that prepare them to deal with
the messy, unscripted problems they will encounter
daily during and after college.”
Instructors and students are often in a race against time to successfully cover and study class material. In the traditional class model, the instructor has more control over the pace of the class. In contrast, instructors relinquish some of this control when they switch to the flipped classroom model. This means that instructors and students must be careful when managing time in the flipped classroom model.
In the flipped classes that Dr. Khasawneh teaches, several strategies are followed in order to optimize the usage of the available time:
The flipped classroom model is successfully applied in Dr. Khasawneh's Statics and parts of Dynamics classes. For the flipped classroom model, and the part of Dynamics that has not been flipped, the students are given pdf templates that include a bare-bone of the video or lecture that is being presented. The students then would fill in the missing information and add their own comments onto the template. In the non-flipped parts of Dynamics, the students are asked to print and bring the pdf template with them to class. This alleviates the students from spending precious class time copying a problem statement; instead, time is utilized to discuss concepts and tackle the problem solution, which helps keep the students engaged. The pdf templates contain pictures from the textbook as well as a fair amount or original artwork that Dr. Khasawneh has created using open-source tools. These templates are then used to produce videos for the flipped classroom model or to deliver lecture material. Specifically, the technology used to create and record class material includes:
The videos and the un-annotated pdf templates are made available to the students on Blackboard. During the videos, the students are often challenged to pause the video and try to solve a certain problem or parts of it. The students are instructed to use the videos for hints or to check their solutions. The students are also required to bring their annotated notes to the classroom along with any questions they may have about the presented material.
