Using Videos to Explain Problem Examples

This article may be helpful to faculty members in the areas of mathematics and science who are considering utilizing video podcasts as support materials to help students work through problem sets for their class. Please note that although the journal article mentioned below is free to access, you will need to establish a username and password on the journal site to do so.

In the article “Developing a Framework for Creating Effective Instructional Video Podcasts” R. H. Kay studied the development and use of videos to share “worked examples” online with students. Worked examples are “instructional devices that provide an expert’s problem solution for a learner to study” (Atkinson, Derry, Renkl, & Wortham, 2014, p. 181).  Kay then used these findings to develop a framework organized into four main categories:

  • Establishing Context
  • Creating Effective Explanations
  • Minimizing Cognitive Load
  • Engaging Students

as well as 16 subcategories which can be viewed via the article link above. Please see page 24.

Course Hub Review

The Course Hub is a meta-platform for aggregating resources for a given course across a variety of platforms including WordPress and Moodle.  Below is a screencast showing how the Course Hub has been used in courses this fall.

Clickers in a large lecture class – Catherine Combelles

What: Clickers (personal polling devices) in a large lecture class

Who: Catherine Combelles, Assistant Professor of Biology

Class: BIOL0145 Cell Biology and Genetics

Technology Used: Personal Polling Devices (Clickers)

Number of students: approx. 70

Learning objective: To monitor the students’ understanding of concepts covered in lecture and promote peer learning and discussion.

Description of use: Catherine used the clickers for every lecture from day 1 to the last day of classes, and throughout the duration of each lecture. At the beginning of each lecure, she started with a question that tested their understanding of concepts from the past lecture or on their readings for the day. She would then pose between 3-4 more questions depending on the lecture content that day. Continue reading “Clickers in a large lecture class – Catherine Combelles”

Middlebury Trailrunner Blog – Jeff Byers

middlebury-mapleWhat: Middlebury Trailrunner Blog

Who: Jeff Byers, Professor of Chemistry and Biochemistry

Technologies used: Hardware: GPS watch, digital camera.  Software:  Google Earth, WordPress, Garmin software (allows seamless connection to Google Earth). When posting an altitude profile, Jeff does a screen shot off of the Garmin software and pastes it into MS Word.  Then he uses a shareware program called “Doc to Jpeg Converter” and crops it with Microsoft Office Picture Manager.

Wireless Projection – Chris Watters

ChrisWatters003-croppedTechnology used: Wireless Video Presentation System II by BlackBox
Course: BIOL0222A Human Nutrition from an Evolutionary Perspective (Winter 2010)
Reason for using the technology: This was a seminar course, and Chris wanted students to be able to present from their own laptops.
Received assistance from: LIS HelpDesk and Media Services

The BlackBox Wireless Video Presentation System allowed the nine students in Professor Chris Watters’ Human Nutrition class to share their work as peers rather than as presenters at a podium.  Discussion continued seamlessly through PowerPoint presentations that students ran from their own laptops.

Chris can envision other uses for this technology, including collaboration and peer review, and more simply, large projector presentations.  He first saw the BlackBox server in action at an international visualization conference in 2005.  A group would demonstrate a project, take feedback, make revisions, and present again.  When Chris learned that the server was available in the US, he mentioned it to Dean Cadoret.  Dean found the server and helped configure it with other LIS staff.

Full configuration remained difficult despite adjustments to the server, the network, and even the students’ laptops.  Some of Chris’ objectives couldn’t be met (he had hoped students would be able to pull up nutrition web pages and evaluate them as a group), but overall Chris found this experiment with new technology worthwhile.
