Spell Bowl Simulator

• Team members
• Richard Charts
• Phillip Zink

12
What is Spell Bowl?

• Spelling competition that differs from
  traditional spelling bee in which students write
  down the spellings after they are spoken and used
  in context
• KES competes at grade levels 4-5 with teams of
  8-10 students.

13
The Simulator

• Adequately prepare KES students for upcoming
  Spell Bowl competitions
• Work through an interface that is both simple and
  user-friendly
• Provide immediate feedback to the students
• Structure in such a way that potential future
  simulator expansion is facilitated

14
Implementation

• The main part of the Simulator is a Java Applet
• Simulator is web-based and compact
• There is also a website that saves student scores
  and allows teacher review
• The website was built with php
• The scores, login information, and words and
  sentences in a MySQL database

Quiz Bowl

• Project Team Members
• Kenny Bailey, Chad Loewenstine, Chiran Perera

Quiz Bowl

• Quiz Bowl is an 8 player wireless buzzer system
  to accommodate learning through competition.
• Students can compete with each other in teams or
  individually
• Teacher can adjust allowable time limit for
  response
• Teacher queries and then mandates when response
  time begins
• The first student to buzz in gains admission to
  respond to the question

21
How it works

• When a student activates the buzzer, a signal is
  processed and transmitted by a Ming transmitter
  circuit.
• The signal is received by its corresponding
  receiver circuit in the main console unit.
• All of the signals are decoded and then sent to a
  programmable logic device which handles the logic
  of all those signals and the timer-circuit.

23
How it Works

• The PLD then sends out the corresponding signal
  through a comparator and uses an FET to power a
  12-V bulb.
• Reset then resets the system for further play.

24
Quiz Bowl Improvements

• The Quiz Bowl was redesigned this semester to
  remedy aspects of the system that made it
  unreliable.
• New switches
• Larger batteries and battery holders
• LED on/off indicators
• New internal wiring

25
Quiz Bowl Improvements

• Some of the transistors and a capacitor in the
  buzzer-boxes were fixed.
• Some of the transmitter circuits were retuned for
  more accurate transmission.
• During testing and retuning some further problems
  developed.
