This presentation examines the vital role of technology in enhancing math and science instruction. It emphasizes the accuracy of visual aids, the display of animations, and the potential to boost student motivation and promote autonomous learning. While technology offers numerous benefits like improved outcomes and time efficiency, it also presents challenges, including classroom management and the need for adequate teacher training. We explore various technological tools and resources that can transform the educational experience in high school and elementary science classrooms.

Transcription de la présentation

  1. Technology in Science & Math instruction Presented by Yasumasa Shigenaga, Kara Johnson, Kathie Kehl

  2. Introduction "We should all be concerned about the future because we will have to spend the rest of our lives there." Charles Francis Kettering, Seed for Thought, 1949 • The use of technology in math and science instruction enables: • Accuracy of diagrams, illustrations • Display animations and movements • Enhances interest and motivation • Nurtures autonomy in learning • Changes outcomes more easily • Saves time and prevents mistakes

  3. Cautions & Constraints Classroom Management Time Constraints Technical Difficulties Monitoring use and abuse Monetary Technical Support Availability Adequate Teacher Training

  4. Technology in High School Science • Technology integrated into the high school classroom • Authentic learning experiences • Edutopia.org • Compare text to technology • Studio Daily Cell video

  5. Technology in Elementary Science • Animals • Video: • National Geographic Kids • Water Cycle • Diagrams/animations: • EPA.gov • Earthguide.ucsd.edu • Sweetwater.org

  6. Values of a, b & c in quadratic functions and their graphs Lesson plan prepared by Mr. Katsuhisa Tomoda (math teacher at Osaka Kyoiku University Ikeda High School; http://www.criced.tsukuba.ac.jp/grapes/)

  7. In the quadratic function y=ax2+bx+c, what relationship exists between the values of a, b & c and the shape of the graph?

  8. y O x Value of a and the graph In the quadratic functiony=ax2+bx+c,how does the value of a influence theshape of the graph? #2

  9. Value of aand the graph (cont.) a=2 When you change the value of a in y=ax2+bx+c, the width and the direction of the graph changes. Therefore, the value of a signifies the width and the direction of the graph. y a=1 a=0.5 O x a=-0.5 a=-1 a=-2

  10. y 2 1 O -1 1 2 3 x -1 -2 Value of c and the graph In the quadratic functiony=ax2+bx+c,how does the value of c influence theshape of the graph? #4

  11. Value c of and the graph (cont.) When you change the value of c in y=ax2+bx+c, the graph moves upward or downward without changing its shape. The value of c signifies the y intercept. y c=2 2 c=1 1 c=0 O -1 1 2 3 x -1 c=-1 -2 c=-2

  12. y 2 1 O -2 -1 1 2 x -1 -2 Value of b and the graph In the quadratic functiony=ax2+bx+c,how does the value of b influence theshape of the graph? #6

  13. Value of b and the graph (cont.) When you change the value of b in y=ax2+bx+c, it is not entirely clear what the value b signifies. y 2 1 O -2 -1 1 2 x -1 -2

  14. y 3 2 1 O -2 -1 1 2 x -1 Value of b and the graph (cont.) In y=ax2+bx+c, let’s find a property that does not change even when the values of a and c are changed. #8

  15. Value of b and the graph (cont.) When you change the value of a in y=ax2+bx+c, the graph always touches a straight line. Let’s examine the relationship of this line and the quadratic function. #9 y 3 2 1 O -2 -1 1 2 x -1

  16. Value of b and the graph (cont.) a=4 When you substitute 0 for a in y=ax2+bx+c, the straight line y=bx+c is obtained. Therefore, the value b signifies the slope of the tangential line on the y axis. y a=2 3 a=1 2 a=-1 1 a=0 O -2 -1 1 2 x a=-2 -1 a=-4 y=bx+c

  17. MathType 6 • Compatible with Vista/XP/Macs • Compatible with Word (2007 & older) • Free for 30 days • and then it reverts to MathType Lite—with Equation Editor, fonts, & symbols • $97 ($57 academic) • http://www.dessci.com/en/products/mathtype/default.htm

  18. MathType 6 • Features and Benefits • Fonts, symbols, templates • Ingrates tabs and toolbars in many applications (including Word, Powerpoint, and Excel) • Can add equations into virtually any application • Quick and automatic reformatting of equations

  19. WebEQ • Interactive math on webpages • Compatible with Windows (XP and older, not Vista) and Macs • Free for 30 days • $495 ($99 academic) • http://www.dessci.com/en/products/webeq/

  20. WebEQ • Editor for creating equations • Publisher—can create: • an entire HTML page • MathML • Images • Applet tags • Interactive WebEQ controls: • Input, viewer, graph, evaluate

  21. WebEQ • Drawbacks: • Needs MathPlayer, WebEQ Viewer Control, or Java installed to display MathML • Not compatible with Vista • Not intuitive (although there is a solutions & examples section)
