How can instructors use Tablet PCs to advantage in and out of the classroom?

The Challenge



2002 Clemson Laptop Mandate

Every student is required to have a laptop computer with wireless access to the Internet


The Challenge

How can instructors use the laptop computers to advantage in and out of the classroom?


Web-based software tool to help promote interactivity in the classroom

Clemson’s Proposed Solution: MessageGrid


Web-based Basic grid: rows and columns Instructor designs grid Students post original submissions or

replies to submissions Anything displayed by a browser

• Text, image, audio, video, animation, Ink, maps Why use such a tool?

• Student responses to in-class exercises, presentations, online discussions, student questions, feedback from students, …

Proposed Solution: MessageGrid

MessageGrid Evolution

Every semester since January

2004, more instructors use MessageGrid

At semester’s end, instructors discuss possible improvements

Suggestions with most instructor

support are implemented

Current MessageGrid Features

Has MessageGrid Changed Teaching?

Teaching Style

Studio Format (aka Mentoring, Coaching)• Reduced lecture• More classroom activity/interactivity


Teaching Style

Studio Format (aka Mentoring, Coaching)• Reduced lecture• More classroom activity/interactivity

Typical 75-minute lecture period• Data structures and algorithms• 20-minute lecture, 5-minute exercise,

repeated 3 times Typical 110-minute lab period

• 15-minute lecture, 95-minute lab exercises

Tablet Use at Clemson

HP Tablet PC Video

Tablet PCs can provide• Final Inked solutions• Intermediate Ink stroke sequences

Ink strokes can be• Collected• Played and replayed• Tagged and analyzed

Key Observation



33

For example: Can provide interactivity in a data structures class (drawing graphs)• Instructor assigns exercises• Students submit solutions• Evaluation of solutions• Tagging of solutions• Analysis of tags



34

Student solutions can be• Reviewed: Played and replayed• Tagged • Analyzed

Solutions include:• Linked lists• Stacks• Queues• Trees of all types (BST, AVL, Splay,

B-Tree, binary heap, leftist heap, skew hap, binomial queue, etc.)

• Generic graphs

Goals

Immediate goal• Deliver CS2/CS7 course content more

effectively

Long term goal• Understand thought process of CS2/CS7

student• Early identification of students at risk
