Online Science Videos: Design, Production, and Impact on Student Learning Patrick Boggs 1 and Jim Brinson 2 1 Office of Instructional and Online Technologies, Ivy Tech Community College, Terre Haute, IN, 47802 2 School of Science and Technology, American Military University, Charles Town, WV, 25414
Introduction and Context: The Need for Videos in the Online Science Classroom Difficult to establish a student/instructor and interactive “human” relationship through an online environment. Some question that online learning can be as effective as traditional learning, particularly for science courses with a manipulative lab component. One way to help remedy this, as well as to teach more abstract scientific concepts online, is to write, develop, produce, and effectively implement visual media and instructional laboratory videos.
Objective: Successful Video and Best Practices To design, produce, and map the success rate of online instructional videos created to supplement seven science labs for an online physical science course, and to develop a system of technological and pedagogical best practices. The Primary Question From the students’ perspective, will instructor-produced video help establish teaching presence and foster learning in an online course?
The Secondary Questions Will students perceive these videos as worthwhile and credible? Will the students report that these videos are important to their online learning experience, and will course scores and attrition data support this claim? What type of instructional products would the students like to see more of in this course? What will we learn about creation, production, and distribution of the videos, and what would we do differently for future videos?
Methods and Design Project spanned from 2007-2011 Instructional laboratory videos were written and produced to accompany at-home laboratory assignments and then integrated into the Blackboard classroom (videos were required viewing in the course) End-of-course survey administered to a random student sample taken from multiple sections of an online general education physical science course (response rate = 80.4%) to assess usefulness and impact of videos on student learning Student course performance was analyzed and correlated with student claims on survey
The Survey Contained 17 closed-ended questions (7 five-level Likert items, 5 yes/no items, 1 ranking item, 4 multiple choice items) and 1 open-ended comments question Representatives from the science teaching faculty and the distance education and instructional and online technologies offices developed the questions Web-delivered, password-protected, and released randomly to participating course sections
Video Equipment Shot with a Canon XL-1 standard definition camera with BeachTek XLR adapter and VariZoom VZ-PRO-F Fujinon 8-pin Pro Zoom control Various tripods, bounces and scrims, and lights were also used Audio was recorded using a Samson lavalier microphone and receiver Any additional video, text, images, or graphics added that was not part of our original video was in the public domain or licensed with Creative Commons copyright
Video Equipment, cont’d Video animations were created using Adobe Flash and Apple Final Cut Pro Video distribution included streaming video (with different bandwidth options that could give a 640x480 presentation), downloadable video and audio mp3 (using Techsmith’s Camtasia Pro), and DVD. All options were free and linked in the virtual classroom except for the DVD, for which students were charged $3.00 for cost of materials
Attrition Rates and Academic Performance (Prior to and after Implementation of Video)
Student Benefit from Videos = Strongly Agree or Agree = Neutral= Disagree* *There were no Strongly Disagree responses 94.1% 91.2% 88.2% 81.5% 5.9% 8.8% 8.6%3.2% 8.6% 3.2% 15.3%3.2% Meeting/hearing/ seeing the instructor is valued Meeting/hearing/ seeing the instructor is valued Instructor-student relationship is important Enjoyed watching videos Videos aided in content learning Videos had a direct (+) impact on final grade
Student Benefit from Videos = Strongly Agree or Agree = Neutral= Disagree* *There were no Strongly Disagree responses 85.3% 88.2%9.3% 8.6% 2.5% 6.1% Videos needed for students to succeed Want more content-related videos
Student Viewing Frequency and Experience with Online Learning = Yes = No *There were no Strongly Disagree responses 90.7% 88.8% 61.6% 31.3% 11.3% 9.3% 11.2% 38.4% 68.7% 88.7% Watched all of the videos Watched at least one of the videos two or more times Watched 2-6 of the videos two or more times Watched all of the videos two or more times First time taking an online course
Preferred Media and Access Data Preferred Instructional Media Preferred Methods of Video Access (0%) = most preferred in category
Connection Speed and Location Used to View Videos (0%)
Summary of Results and Findings When instructional videos were added as supplements to already existing lab assignments, the mean overall course grade increased 6.1% When instructional videos were added as supplements to already existing lab assignments, course completion increased 18.4% Students enjoyed watching the videos and valued the instructor interaction they provided Students found the videos to be helpful, and to have directly impacted their academic performance
Summary of Results and Findings, cont’d Students want to have more content-related videos in the course, and videos remain the 1 st preference of instructional media among students Students prefer streaming video over other video formats Students often viewed the videos multiple times Almost all students primarily viewed the videos from home using a cable or DSL connection speed
The Take-Away… Overall, data from this project clearly indicates that, from the students’ perspectives, the time and effort it takes for an instructional design team (instructor, instructional technologist/designer, producer, etc.) to develop and produce course video(s) are valued and validated.
