Summer 2013 RET Summary Joe Foy Math Teacher STEM Academy Knoxville, TN

1-2 Statement of Research A primary research area was proposed in the Spring of 2013; to define a high school programming course which would satisfy requirements of the Advanced Placement authorizing agency, and which would also involve power application problems

1-3 Statement of Research The scope of the effort was expanded during the first week of RET to include definition of a prototype assembly language course, targeting high school students

1-4 Wind Analysis Program Permits user to select a month and one of three types of analysis for that month  Power density vs. time of day  Average speed vs. time of day  Hours vs. wind speed Input data is year 2012 wind data for location “Seven Mile”

1-5 Wind Analysis Program “Seven Mile” data  Measurements every 5 minutes  Includes missing measurements (NaN) and invalid measurements (i.e. wind speeds of mph)  Speeds in MPH, output data is in meters/second and Watts/sq-meter

1-6 Wind Analysis Program Java permits graphics creation, but does not have a library of graphing utilities, such as bar charts, pie graphs, etc.  Freeware software exists; i.e. JFreeChart Therefore the analysis program creates a text file (.csv), which is then read by Excel, which can quickly create a scatterplot

1-7 Wind Analysis Program ….. Demo software…..

1-8 Wind Analysis Program: Results AP Computer Science Syllabus was created, will be submitted the first week in August to the agency with AP credit oversight. Chapter guides were created, textbook provided instructional powerpoints were edited\modified. Material includes several power application problems

1-9 Wind Analysis Program: Results Several of the RET analysis tasks are defined as single labs in the AP CompSci syllabus  Chapter 2: Convert MPH to m/s  Chapter 2: Single Wind Power Density calculation from prompts Chapter 5 Programming Project: calculate power line transmission loss from prompts (transmission distance, voltage, required load power)

1-10 Wind Analysis Program: Results Chapter 6 Array Project: students will do one of the three Wind Analysis problem types, including file I/O, that were accomplished during RET

1-11 An Assembly Language Course: Results A prototype Assembly Language course is still being defined. Assembly language programming skill was developed during RET via two programs.  LED Count indicator  ADC read\convert\LED display

1-12 An Assembly Language Course: Results Programs involved  Coding and locating initialization and interrupt routines  Configuring and managing two on-board timers (TIMER0, TIMER1)  Configuring and managing two GPIO ports (PORTA, PORTC)  Configuring and managing an embedded 10- bit ADC

1-13 An Assembly Language Course: Results Two texts were purchased (private funds) both will be referred to in the school year 2013 – 2014 course. The course will be fashioned around  The PIC 16F88 and 16F616  MPLAB’s MPASM assembly language IDE  HIGH-TECH C C-language compiler  PICDEM2 board

1-14 An Assembly Language Course: Results The course sequence will include not only guided instruction through basic assembly language programming skill, but also definition of a battery powered hand-held instrument.

1-15 RET Summary Materials purchased with the RET stipend include  Six spark timers, will be used in Honors Algebra 2 and CP Calculus courses  Two PICDEM2 development boards  One MyDAQ, one myGrid

1-16 RET Summary Extensive and encouraging support was provided by CURENT staff, in particular  Dr. Chien-fei Chen  Dr. Wei Gao  Erin Wills  Adam Hardebeck This RET participant is grateful for an extremely unique educational experience
