The paper I chose to read this week talks about two overlapping learning mediums: video and hybrid learning.
I am currently learning about designing and teaching online courses. I have had doubts about my ability to engage my students in the content from a distance. The web environment places more personal responsibility on the student than on the teacher, as Lents and Cifuentes observe. In addition, my discipline requires laboratory experiences to increase comprehension and connection to the student’s life and future career. Simply replacing these experiences with computer simulations may not be enough. The authors lobby for a “middle ground”: the introduction of web-delivered video lectures to replace a portion of traditional classroom lecturers.
Lents and Cifuentes identify some problems with this approach: there is no record of attendance, students won’t get instant feedback to clear up misunderstandings, the delivery is inherently less engaging, and there is less social interaction (2009). Still, they ran their experiment. They prepared an experimental and a control group of students to take their basic majors Biology course. They would measure student success by their exam results. The software they used for the video lectures was Camtasia.
The students who received the video lectures did poorly in their first exam. The instructor then had a discussion about the process of learning by video lecture. The students who were against the video lectures replied that they had trouble staying focused. However, many students were enjoying the video lectures and found several advantages to them: they could pause frequently to take notes and check their textbooks and they could re-watch the lecture several times. After their discussion session, the grades of the experimental group improved greatly.
Before the third exam, the students answered a survey to choose the delivery method for the last portion of the course. They decided that a normal lecture would be delivered AND recorded for web posting, so students could choose the method that worked for them: this was reflected in their high grades. Lents and Cifuentes conclude that the introduction of web-based video instruction can be used successfully.
This project was a digital-age learning experience (NETS-T 2) because the instructor developed a technology-enriched learning environment, and personalized the delivery method to reach different types of learners; plus the researchers used the data from their experiment to improve teaching and learning. The instructor delivered the lecture by using a digital age medium, demonstrating fluency in the technology (NETS-T 3, Model Digital-Age Work and Learning). The most important part of the project for me, was that the instructor identified a problem with the delivery method and then discussed it with the students and involved them in the decision to change it. I think this was in line with NETS-T 4, Promote and Model Digital Citizenship and Responsiblity, specifically “address the diverse needs of all learners by using learner-centered strategies providing equitable access to appropriate digital tools and resources”.
