Two Awesome Graduate Students Instructors:

Joel Vaughan and Dave Childers

Department of Statistics, University of Michigan

The PreLabs project was funded through a NINI Grant (New Initiatives/New Infrastructure) from UM LSA-ITC (Instructional Technology Committee):

“Enhancing Undergraduate Education Through the Deployment of Quality Learning Objects”

Course Background

• Stats 350: Introduction to Statistics and Data Analysis

– Over 1450 students this term.– Consists of lectures and weekly computer lab.– Part of lab involves analyzing data using SPSS.– Still some diversity in students’ computer skills.– A number of difficult concepts for students to grasp –

often deal with ‘what if you repeated the procedure many times?’ – theory based, not in practice.

Big Idea about PreLabs

5

• Problem: Lab time better utilized if students arrived with…

(1) common prior exposure to the core statistical ideas, and

(2) basic familiarity with statistical software package (and teaching basic HOW TO steps in a lab is boring!)

• Solution: PreLabs– Screen capture software (Jing) used to create videos.– Video(s) and short assignment together form a PreLab.– Made available to students at appropriate times in course.

What is Jing?

Jing = Screen Capture Softwarewhich allows snapping a picture of (part of) your screenor recording your screen activity with audio commentary

Jing

• Advantages: – Free– Easy to Use– Captured Shots or Videos can be saved or

automatically uploaded– Formats great for the web

• Disadvantages: – Maximum Video Length: 5 minutes– Can mark up Screen Shot, but no video editing– Videos are branded– Video format not always what one would want

7

Using Jing

• Instructions for Use: 1. Choose “Capture” from the Jing Sun.

2. Select the window of area you wish to record.

3. Select Screenshot or Video. Record.

4. Preview it.

5. Save it locally, or upload it to Screencast.net.

8

Using Jing

• Helpful Hints: –Use “Pause” feature often to reduce extra takes!–Adjust screen resolutions to provide a

“whole screen view" in a smaller video size.–A headset/microphone combination

is a worthwhile investment.– Use the cursor locate feature to help viewers

follow the cursor.

Other Screen Capture Software

• Free: – Jing: very convenient jingproject.com– CamStudio: More features than Jing

(AVI or SWF Screen Annotations) camstudio.org

• Not Free: – Jing Pro: Provides longer video limit,

larger online storage, no branding. jingproject.com

– Camtasia: “Jing's Big Brother:" Advanced editing, much longer videos. techsmith.com

– BSR Screen Recorder: Limited Editing, multiple formats. bsrsoft.com

Example #1 of Video Wrappers in Statistics for addressing needs

• Goal:–Spend more lab time discussing

Statistics, less time on software.

• Video Wrapper Solution:–Create video tutorials explaining software usage

with Jing, and presented with other resources through UM.SiteMaker. sitemaker.umich.edu

Example #2 of Video Wrappers in Statistics for addressing needs• Goal:

–Make online learning resources more accessible and useful to students.

• Video Wrapper Solution:–Create video wrapper demonstrating the

features of a learning resource with Jing.

• Video Wrappers Can:–Show students what to look for in the resource.–Adjust for notational differences–Correct mistakes in resource, if necessary.

• Prelabs received very well by GSIs (TAs) that teach the lab sections as they better prepared their students for the upcoming discussion topic.

• Shared knowledge can be then assumed for lab.

• GSI comment:

“ My students came to lab with questions. They were curious as to why they observed the results they did in the prelab, and wanted to ask questions and better understand.  Making them think before lab about discussion topics was very beneficial for class interaction.”

Video Wrapper PreLab Summary

• Students able to cover the PreLab at their own pace and came to labs more prepared to discuss and further learn.

• Student comments:

“The PreLabs utilize what we talk about in class and the homework assignments.”

“They are pretty useful as they are, but the applet based ones are the most useful.”

“PreLabs are currently fine the way they are because they are meant to familiarize the person with SPSS and that is what they do.”

More Examples of Video Wrappers for addressing other Needs

• Quickly/effectively answer students’ questions– Record a video– Upload it to screencast.com– Send the link to the student– A graphics tablet or tablet PC can be useful

• Provide GSIs with video steps for any HOW TO DO IT task– How to set the CLICKER settings for saving responses– How to Export your Gradebook

to send to coordinator for back up of files
