Good afternoon...

EXAMS:

Students who missed their Fall Semester 2020 End-of-Course or CTE state assessments will take their make-ups on May 19-24 otherwise you will receive a 50 for their exam grade in these courses. IF Applicable complete: Fall 2020 Make-Up Testing Form.

Spring Semester and A/B Yearlong Testing will occur May 25-28. If applicable, please complete the 2021 End of Year Testing Survey.

Both of these surveys will close on Tuesday, May 4, at 5:00 p.m.

Please see the schedule for the AP Test. The AP exam for CSP is on 5/26. It is online. There is some software that needs to be installed on the device you will be using. I will send you the details ASAP. Please let me know if you will be using a DPS Chromebook or a personal Chromebook. Please see the attached reference sheet. You can use this during the test.

The Create Project is due on 5/20. You should have started your project and a clear plan for completing it.

DON’T DELAY.

NOTE: LOTS OF VIDEOS...Below are my suggestions regarding which videos or parts of a video you should watch. My giving a video a start and stop times both equal to 0.00 is not meant to besmirch a video’s quality. Rather, these videos are focused on specific topics and perhaps not the best use of your limited time.

Note: the order to watch the videos is not the same as the video numbers.

Note: videos 11,12,10,9 are for the Create Project

NOTE: The exam is programming language agnostic.

That is, it does not use a specific language that a school course may have used.

The exam uses a pseudo-code that presents programming concepts found in most languages. This pseudo-code is described in videos 6 & 7.

NOTE: lists are single-term variables that allow for storing multiple values.

Such as (in Python): var cars = [“Ford”, “BMW”, “Honda”, “Volvo”] or vars num = [34.61,7,930,42]...Individual values are accessible by index. The pseudo-code starts indexing at 1. Python starts at 0. SEE VIDEO 7 first 20 minutes.

Any questions?

A Little History...

Communication has been a struggle for all of human history. Coding has been critical for messages be they of war or love. Prior to the mid-1800s, long-distance communications was limited by the speed of a runner, horse, ship, or perhaps carrier pigeon. Our ability to generate and modulate electricity changed the speed and convenience of communications, but not the need for privacy. Early networks were built around the telegraph and later the telephone. Direct wiring of devices was expensive and limited to a few offices, factories, or ships of war. Early computers, first appearing in the 1940s, were stand-alone devices. A CPU "communicated" with its storage devices, control panel, printer, and punch-card unit. The demands of war prompted massive investment in communications systems with computers receiving data from widely dispersed sources. SAGE & DARPA being prominent examples of such systems. Such technologies soon appeared in non-military applications with SABRE airline reservation system and ARPANET appearing in the 1960s. Progress in semiconductor technology led to CPU shrinking from the room-size behemoths of the 1960s to the fingernail-sized heart of today's PC, phones, and many other devices. Alone with the explosion in device numbers has been the growth in interconnectedness. Networking is our way of life.
