levine s technology theorem

Levine’s Technology Theorem

Everything works either at home or in my office, and nothing works when I present it.

words of caution
Words of Caution
  • Lecture/teaching model still good
  • Technology will not put us out of business
  • Use technology only where appropriate
  • Can add new dimensions to the classroom
  • Can add new dimensions to student learning
  • Limitations of Technology
  • Do not force its use

some uses of technology as a learning teaching tool
Some Uses of Technology as a Learning/Teaching Tool
  • Course Web Sites
  • Scientific Notebook
  • Teaching with computers
  • Teaching in a laptop classroom
  • Mathematical slide shows
  • Discovering things using technology

Using Technology to Enhance Teaching and Learning

course web sites
Course Web Sites
  • All the important information about the course
    • Syllabus
    • Office Hours
    • Homework assignments
    • Lecture notes
    • Old Exams with solutions
    • Grades

web site cautions
Web Site Cautions
  • Time considerations in creating a web site
  • Time considerations in maintaining a web site
  • Good support a must
    • Undergraduates or graduates
    • Clever, deal with technical aspects

Using Technology to Enhance Teaching and Learning

Some Approaches That Work

scientific notebook
Scientific Notebook
  • Word processing package with Maple kernel
  • Very user friendly front end
  • Type no code
  • Clicks
  • Interfaces with Web

Using Technology to Enhance Teaching and Learning

Some Approaches That Work

teaching with computers
Teaching with Computers
  • Present subject matter easily
  • Incorporate demonstrations in the lectures
  • Show students how to use software
  • Cautions
    • Must be easy to use
    • Requires a great deal of good support

Using Technology to Enhance Teaching and Learning

Some Approaches That Work

the case for laptops i
The Case for Laptops I
  • Faculty must have laptops
    • PCs in classrooms not adequate
    • Prepare everything before on laptop
    • Should be able to come in, plug in laptop and teach
    • Ideally just a little more difficult than using chalk and a board

Using Technology to Enhance Teaching and Learning

Some Approaches That Work

case for laptops ii
Case for Laptops II
  • Computer labs expensive
  • Students bring lab to classroom
  • Incoming student has state of the art equipment
  • Really use technology while teaching
  • Opportunity for interaction with and engagement of students

Using Technology to Enhance Teaching and Learning

Some Approaches That Work

teaching linear algebra in a laptop classroom i
Teaching Linear Algebra in a Laptop ClassroomI
  • Linear algebra with computers
  • Students with networked laptops
  • Two classrooms in one
    • Laptop covers down – ordinary classroom
    • Laptop covers up – computer lab
  • No written work accepted
  • Download SNB notes
  • Present some material – laptops down!

Using Technology to Enhance Teaching and Learning

Some Approaches That Work

teaching linear algebra in a laptop classroom ii
Teaching Linear Algebra in a Laptop ClassroomII
  • At appropriate points have students do exercises using SNB
  • These were homework problems to be turned in
  • Discuss problem under consideration
  • Project screens of students
  • Use this alternating format – lecture/computer

caveats about teaching in a laptop classroom
Caveats About Teaching in a Laptop Classroom
  • Can do this only with small classes
    • 25 to 30 students
    • Perhaps 45 with an Assistant
  • Technology questions not simple
    • Faculty involved in design of classrooms
    • Requires great deal of support
  • Expect a good deal of frustration at the beginning
  • Ideally should be able to walk in, plug in laptop, turn on projector and teach

Using Technology to Enhance Teaching and Learning

Some Approaches That Work

teaching linear algebra in a laptop classroom iii
Teaching Linear Algebra in a Laptop ClassroomIII
  • Teach mathematics behind the methods
  • Not just a course in clicking
  • Reducing matrices to echelon form
  • Exams
    • Two parts – written and computer
    • Upload computer part
  • Many technical issues!!!

Using Technology to Enhance Teaching and Learning

Some Approaches That Work

mathematical slide shows i
MathematicalSlide Shows I
  • http://attila.stevens-tech.edu/~llevine/
  • These use stream technology
  • How created
  • Power Point good for creating slides
  • Then can easily add narration
  • Real media add-on to converttoreal format
  • Power Point not good for writing math

Using Technology to Enhance Teaching and Learning

Some Approaches That Work

mathematical slide shows ii
MathematicalSlide Shows II
  • SNB is good for writing math
  • Power Point does not read tex files
  • Solution
    • Prepare math using SNB
    • Capture portions of file as graphics files
    • Important these graphics files into Power Point
    • Add narration, convert to real format

Using Technology to Enhance Teaching and Learning

Some Approaches That Work

discovering things using technology
Discovering Things Using Technology

Polynomial solutions of DEs

  • Which equations have a polynomial solution?
  • Nonhomogeneous Hermite equation
  • Using SNB to investigate this
  • Extrapolate general results form specific cases

conclusions
Conclusions
  • The world is changing
  • Technology will become more prevalent
  • Students must be fluent with technology
  • Technology opens new horizons
  • Many approaches
  • Some good, some not so good
  • Try new approaches, identify good ones, develop them
  • No small challenge
