concept maps
Concept Maps
  • A primary purpose of the brain is to process incoming information to find meaning.
  • This task can be made easier if incoming information is presented in visual formats.
  • Concept maps present relationships in graphical form and allow us to understand complex information at a glance.
definitions j d novak
Definitions – J. D. Novak
  • “A concept is a perceived regularity in events or objects, or records of events or objects, designated by a label”
  • “Propositions are statements about some object or event in the universe, either naturally occurring or constructed. Propositions contain two or more concepts connected with other words to form a meaningful statement.”
concept map graph structure
Concept Map Graph Structure
  • Concepts are usually enclosed in circles or boxes.
  • Propositions, or relationships between concepts, are indicated on a line connecting the two concepts.
applications of concept maps
Applications of Concept Maps
  • Structure information in various academic courses
  • Note-taking
  • Aids for brainstorming
  • Providing graphics for presentations
  • Refining creative and critical thinking
  • Planning studies and career
software used
Software Used
  • Concept maps were created using the Institute for Human & Machine Cognition (IHMC) Concept Map Software
    • http://cmap.coginst.uwf.edu/info/
  • Software runs on JAVA
  • Allows the user to add resources
    • web pages, videos
    • PDF documents, etc.
automation to link resources
Automation to Link Resources
  • Motivation: Adding resources to concepts in a Concept Map is a tedious process
    • Need to use the tool over the network
    • Need to identify different resources/resource types that are relevant to a concept
  • So, we need a better/faster way to go from the basic Concept Map to one that has all relevant resources linked to concepts in it
  • Existing large database of material for 12 chapters could be used, but not linked by hand

Creating HTML Concept Maps with Resources
  • A Concept Map and a template HTML file are created using the IHMC Concept Map tool
  • The HTML Concept Map with Resources is generated from the template HTML file using
    • PERL scripts
    • Data repository, that has Keywords linked to different types of resources (Homeworks, Exams, Demos, Labs, Tutorials)
scripts and outline of steps
Scripts and Outline of steps…
  • Using the IHMC Concept Map tool
    • Create the basic Concept Map. The concepts are also Keywords in the database
    • Identify representative resources for concepts in the map
    • Export the Concept Map to a HTML file, which will serve as the template file to be used in the scripts
  • Two PERL scripts are used to convert the template HTML file to a Concept Map HTML file with more number of resources and resource types
    • One script generates a text file with relevant resources for a Chapter and Keywords used in the Concept Map
    • The second script uses the text file and the template HTML file to add more resources to relevant concepts

Dynamic Creation
  • Easy to update as new resources are created
resources for concept map
Resources for Concept Map
  • GUIs: using MATLAB for animation of mathematical concepts
    • Tutorial Videos for usability
  • Homework Problems with solutions
  • Laboratory Assignments
    • Pre-Lab Videos
  • Lectures
    • Short mini-lectures on specific concepts
matlab gui development
Matlab GUI Development
  • Developed the GUI in Matlab to demonstrate properties of Fourier Transform Pairs.
gui movie making
GUI Movie Making
  • Three movies are created for each GUI:
    • Tutorial Movie - Demonstrates GUI functionality and usability
    • Theory Movie - Explains theory and its applications
    • Lab Movie - Exemplifies problem solving techniques using GUIs
  • Use Camtasia Studio & SnagIt software from TechSmith®
  • SnagIt is an image and text capturing software
  • Camtasia Studio is a recording and editing software
  • Movie duration approx. 2-4 min
  • Storage less than 10 MB in AVI format

GUI Movie-making Stages:

  • Record audio and video clips. (Recorder)
  • Produce AVI file from video/audio clips and screenshots. (Producer, SnagIt)
  • Add visual effects. (Effects)
  • Publish in desired format (Producer)
camtasia recorder
Camtasia Recorder
  • Allows for screen activity recording of screen, window, or user specified region.
  • Features include:
    • Audio with cursor and keyboard sounds
    • Zooming
    • Automatic panning
    • Cursor highlight
    • Annotations such as caption or watermark
  • Recorded at 10 frames/sec
  • File saved in AVI format
camtasia producer
Camtasia Producer
  • Editing tool which combines audio and video clips along with image files to produce a movie.
  • Publish in desired format:
      • Audio Video Interleave (AVI)
      • Macromedia Flash (SWF)
      • Windows Media (WMV)
      • Quick Time (MOV)
      • Real Media (RM)
      • Animated GIF
      • Self-running .EXE Real Media (RM)
  • A 2-4 min AVI file is stored at less than 10 MB.
camtasia effects
Camtasia Effects
  • Tool for adding special effects to an already existing AVI file
  • Object are added on a timeline with specified duration
  • Objects can be:
        • Callouts
        • Textboxes
        • Highlights
        • Shapes
        • Freehand drawing
        • Custom bitmaps
tscc codec
TSCC Codec
  • Camtasia uses TSCC codec to compress the audio and video files.
  • It is lossless with high compression ratio, optimized especially for screen capture recordings.
  • Movies require the installation of TSCC codec file tscc.exe.
  • Additional information about the TSCC codec along with its download sites can be found at:

summary
Summary
  • Concept Maps give a structured graphical view of chapters
  • Adding more resources all the time
  • Start trials with large class this fall
