Week 25: Monday, February 24th – Friday, February 28th

Welcome to the end of February! To wrap up Black History Month, I'd like to tell you about John Henry Thompson (b. 1959), the creator of the influential Lingo programming language. The son of Jamaican immigrants, Mr. Thompson got his first opportunity to work with a computer as a 10th grader at the Bronx High School of Science when his geometry teacher, Ms. Strauss, gave him early access to the math department's computer lab and helped him get his first job as a computer operator in the New York State Psychiatric Institute. After graduation, he earned his Bachelor's degree in Computer Science and Visual Studies from MIT in 1983 and continued on as a technical instructor, developed an early color pre-press design system for the Visible Language Workshop, which is now part of the MIT Media Lab. Mr. Thompson then became a project lead at Lucasfilm on the EditDroid project, an early nonlinear editing system that was a precursor to Final Cut, the industry standard in video editing. In 1987 he joined Macromedia (now part of Adobe), where he contributed to the development of a number of products, including Macromedia Director, and he invented the Lingo programming language and XObjects, which made it easier to create interactive multimedia content like Flash, Shockwave and graphics-based CD-ROMs. If you've ever played an interactive game in a web browser, his work helped make that possible! For the past two decades, Mr. Thompson has continued teaching in New York City, Philadelphia, Jamaica, and online, and he has since become an outspoken critic of social media companies such as Facebook for how they use personal data and what he describes as their negative impacts on society.

Here's the plan for this week as we wrap up Unit 8: 2D Array:

• Assignment 8: Battleship

• ACT – NO SCHOOL for Sophomores & Seniors; good luck, Freshmen & Juniors!

• Unit 8 Exam

• Unit 9: Lesson 1 - Inheritance

On Friday 2/28, we'll be visited by Kent State's Computer Science Department! Make sure you come to class with lots of questions about their offerings and what kinds of careers their graduates have gone into.

Good luck to the Freshmen and Juniors taking tests on Tuesday! Remember, no school for Sophomores and Seniors. After this week, we'll only have two weeks before the end of 3rd Quarter, and then another week after that will be Spring Break. Hang in there, and have a great week! Please let me know if you have any questions at all.

Week 24: Tuesday, February 18th – Friday, February 21st

Good morning! I hope you've been enjoying the winter wonderland during this three day weekend. This week I'd like to tell you about Dr. Clarence "Skip" Ellis (1943-2014), the first Black person to earn a PhD in computer science. Dr. Ellis grew up in Chicago and graduated from Parker High School while also working as a part-time night shift security guard for the Dover Corporation. While at Dover, he watched over the company's mainframe computers and became fascinated by them, so he read over the manuals during his shift and learned how to operate and repair the vacuum-tube-based machines. He earned degrees in mathematics and physics from Beloit College in Wisconsin, and while at Beloit, he was one of 10 North American college students to attend a computer science program at the University of Illinois, Urbana-Champaign. Based on his experiences there, he earned his PhD in computer science from Urbana-Champaign in 1969, making him the first Black person to ever do so. Dr. Ellis worked at Bell Labs, IBM, and Xerox, and from 1976–1984, he worked at the Palo Alto Research Center, where he led the team that created Officetalk, the first program to use icons and the Internet to allow for long-distance collaboration. This means that every icon-based app or operating system you've ever used was directly influenced by Skip Ellis. You could say he's "iconic"! (Sorry.)

Here's the plan for this abbreviated week as we start Unit 8: 2D Array:

• Unit 7 Exam

• start Unit 8: 2D Array

• Unit 8: Lesson 1 – 2D Arrays

• Unit 8: Lesson 2 – 2D Array Algorithms

Have a great week – stay warm!

Week 23: Monday, February 10th – Friday, February 14th

Hello again! I hope you've enjoyed your surprise 4-day weekend and stayed warm during the ice storms. This week I'd like to tell you about Dr. Timnit Gebru, a Black computer scientist who studies artificial intelligence (AI), algorithmic bias and data mining. Dr. Gebru was born in Ethiopia and fled the Eritrean–Ethiopian War when she was 15, eventually receiving political asylum in the United States. She earned her bachelor's and master's degrees as well as her PhD from Stanford University. While at Stanford, she worked as an intern at Apple making audio circuitry and later developed signal processing algorithms for the first iPad. After brief stint at Microsoft where she investigated racial bias in facial recognition software, she joined Google in 2018 to co-lead a team the ethics of artificial intelligence. However, in late 2020, her employment at Google was terminated when she refused to withdraw a research paper about the serious risks of large language model AI systems (Dr. Gebru claims that she was fired, while Google has refused to say whether she resigned or was terminated). Since leaving Google, Dr. Gebru has co-founded Black in AI, a community of Black researchers working in AI, and the Distributed Artificial Intelligence Research Institute (DAIR), a "space for independent, community-rooted AI research, free from Big Tech's pervasive influence". She has earned numerous accolades, including being named one of the world's 50 greatest leaders by Fortune Magazine in 2021 and one of Time Magazine's most influential people of 2022.

Here's the plan for this week as we start to wrap up Unit 7: ArrayList:

Next week, we'll take our Unit 7 Test, so make sure you don't forget everything during your time off. Have a great week, and enjoy your 4-day weekend!

Week 22: Monday, February 3rd – Friday, February 7th

Welcome to February, and Happy Black History Month! Before I list this week's activities, I'd like to tell you about Dorothy J. Vaughan (1910–2008), the first African-American female supervisor of the National Advisory Committee for Aeronautics (NACA) who became an expert in digital computers and their applications in NASA programs. Ms. Vaughan graduated from Wilberforce University in Ohio with a degree in mathematics and started out as a math teacher. In 1943, to support our country's efforts in World War II, she joined NACA as a human "computer" who did complex calculations for engineers and scientists. She worked with computers Vera Huckel and Sara Bullock to create an algebraic methods handbook for mechanical calculating machines, and when NACA became NASA, she joined its new Analysis and Computation Division and became an expert FORTRAN programmer. Ms. Vaughan and her countless calculations supported NACA and NASA accomplishments and helped to achieve our country’s aerospace goals. Very impressive!

Here's the plan for this week as we continue Unit 7: ArrayList:

• Unit 7 Quiz 🎈

• Unit 7: Lesson 4 - Linear Search

• Unit 7: Lesson 5 - Selection Sort

• Unit 7: Lesson 6 - Insertion Sort

• Unit 2: Lesson 4 - Classes and Objects

• Unit 2 Quiz

• Unit 2: Lesson 5 - Using Constructors

• Sophomores and Juniors: Register for the PSAT on MyPaymentsPlus!

If you feel like you're struggling to keep up, please ask me for help! My prep period is 4/5th period, my PLC is 6/7th and my lunch is 8th, so you can come up any day during lunch and work in my room to get caught up. You can also skip some of the coding activities from Unit 1 for now, but I recommend eventually going back and doing as many of them as possible. If you have Tuesday afternoons open, that's when RHS Coders Club meets in my room, and a lot of members who are also in AP CS A use that time to work together.

I hope you have a wonderful week! As always, please let me know if you have any questions, and I'll see you in Fall. 🍂

Week 4: Monday, September 9th – Friday, September 13th

Hello again! I hope you had a good weekend and have recovered from all that rain on Friday night. Here's what we're doing this week as we move into our second unit of the course, which begins our journey into object-oriented programming (OOP):

• start Unit 2: Using Objects

• Unit 2: Lesson 1 - Strings and Class Types

• Unit 2: Lesson 2 - Escape Sequences and String Concatenation

• Unit 2: Lesson 3 - String Methods

Fortunately, we already have an idea of what Strings are, so we can use them to ease into OOP by learning to use some common String methods (functions) that will likely make an appearance on the AP exam in May.

I also sent home PSAT practice exams for all sophomores and juniors in the class. The PSAT takes place on Wednesday, October 9th in the morning at RHS and costs $19. It's a good way to practice for the full-length SAT, but more importantly, it's the qualifying exam for the prestigious National Merit Scholarship. Doing well on the PSAT could really pay off, and it looks good on a college application. Registration begins on September 20th on MyPaymentsPlus - I highly recommend taking it!

Have a great week, and let me know if you have any questions!

Week 3: Tuesday, September 3rd – Friday, September 6th

Have a great week! Hang in there – we're almost done.

Week 31: Tuesday, April 9th – Friday, April 12th

Hello again! I hope you survived the solar eclipse and enjoyed your bonus 3-day weekend. Here's what we're doing for this week as we wrap up the last topic in the course:

• finish Unit 10 Exam 🥨 

• work on practice exams and FRQs

Now that we've finished all of the material in the AP Computer Science A course, we can focus on getting you ready for the exam in May! My goal is to provide you with class time to study and work on practice questions so that you don't have to do any of that at home. Congrats on making it through to the end! Let me know if you have any questions.

Week 30: Tuesday, April 2nd – Friday, April 5th

Welcome back! I hope you had a fun and relaxing Spring Break and are fully recharged and ready to prepare for the AP Exam in May. Here's what we're doing for the first week of April as we continue our work in Unit 10: Recursion:

• Unit 10: Lesson 3 - Binary Search

• Unit 10: Lesson 4 - Merge Sort

On Monday, April 8th, the Great American Eclipse will take place as a rare total solar eclipse goes across North America, including most of Ohio. Here's some useful information about the timing of the eclipse:

• 1:59:28 pm: Partial eclipse begins - the moment the edge of the Moon touches the edge of the Sun is called "first contact"

• 3:14:30 pm: Totality begins 😱 - the moment the edge of the Moon covers all of the Sun is called "second contact"

• 3:15:54 pm: Maximum eclipse‼️ - this is the deepest point of the eclipse, with the Sun at its most hidden

• 3:17:17 pm: Totality ends 😭 - the moment the edge of the Moon exposes the Sun is called "third contact"

• 4:29:17 pm: Partial eclipse ends - the moment the edge of the Moon leaves the edge of the Sun is called "fourth contact"

There's also a really cool interactive map of the eclipse path, and you can find out all about the many, many eclipse-related events happening this weekend in Kent at the Kent Total Eclipse 2024 website. Make sure to build a pinhole projector out of cardboard and aluminum foil ahead of time – they're really cool and easy to make!

I hope you have a great week back from Spring Break! As always, please let me know if you have any questions.

Week 26: Monday, February 26th – Friday, March 1st

Welcome to the end of February! To wrap up Black History Month, I'd like to tell you about John Henry Thompson (b. 1959), the creator of the influential Lingo programming language. The son of Jamaican immigrants, Mr. Thompson got his first opportunity to work with a computer as a 10th grader at the Bronx High School of Science when his geometry teacher, Ms. Strauss, gave him early access to the math department's computer lab and helped him get his first job as a computer operator in the New York State Psychiatric Institute. After graduation, he earned his Bachelor's degree in Computer Science and Visual Studies from MIT in 1983 and continued on as a technical instructor, developed an early color pre-press design system for the Visible Language Workshop, which is now part of the MIT Media Lab. Mr. Thompson then became a project lead at Lucasfilm on the EditDroid project, an early nonlinear editing system that was a precursor to Final Cut, the industry standard in video editing. In 1987 he joined Macromedia (now part of Adobe), where he contributed to the development of a number of products, including Macromedia Director, and he invented the Lingo programming language and XObjects, which made it easier to create interactive multimedia content like Flash, Shockwave and graphics-based CD-ROMs. If you've ever played an interactive game in a web browser, his work helped make that possible! For the past two decades, Mr. Thompson has continued teaching in New York City, Philadelphia, Jamaica, and online, and he has since become an outspoken critic of social media companies such as Facebook for how they use personal data and what he describes as their negative impacts on society.

Here's the plan for this week as we wrap up 2D arrays and move into Unit 9: Inheritance:

• Assignment 8: Battleship

• Unit 8 Exam 🍝

• start Unit 9: Inheritance

• Unit 9: Lesson 1 - Inheritance

Remember, no school for Seniors on Tuesday due to the ACT. As always, please let me know if you have any questions. Have a great week!

Week 25: Tuesday, February 20th – Friday, February 23rd

Hello again! This week I'd like to tell you about Dr. Clarence "Skip" Ellis (1943-2014), the first Black person to earn a PhD in computer science. Dr. Ellis grew up in Chicago and graduated from Parker High School while also working as a part-time night shift security guard for the Dover Corporation. While at Dover, he watched over the company's mainframe computers and became fascinated by them, so he read over the manuals during his shift and learned how to operate and repair the vacuum-tube-based machines. He earned degrees in mathematics and physics from Beloit College in Wisconsin, and while at Beloit, he was one of 10 North American college students to attend a computer science program at the University of Illinois, Urbana-Champaign. Based on his experiences there, he earned his PhD in computer science from Urbana-Champaign in 1969, making him the first Black person to ever do so. Dr. Ellis worked at Bell Labs, IBM, and Xerox, and from 1976–1984, he worked at the Palo Alto Research Center, where he led the team that created Officetalk, the first program to use icons and the Internet to allow for long-distance collaboration. This means that every icon-based app or operating system you've ever used was directly influenced by Skip Ellis. You could say he's "iconic"! (Sorry.)

Here's the plan for this week as we begin Unit 8: 2D Array:

• start Unit 8: 2D Array

• Unit 8: Lesson 1 - 2-D Array

• Unit 8: Lesson 2 - 2-D Array Algorithms

Two-dimensional (2D) arrays can be pretty challenging, so we're going to take this topic slowly and use some graphical organizers to make sure you understand what's going. If you think of a 2D array as a grid, like a chessboard, then they're a lot easier to visualize, which should make it a little easier to figure out how to implement them. Enjoy your abbreviated week, and as always, please let me know if you have any questions!

Week 24: Monday, February 12th – Thursday, February 15th

Hello again! This week I'd like to tell you about Dr. Timnit Gebru, a Black computer scientist who studies artificial intelligence (AI), algorithmic bias and data mining. Dr. Gebru was born in Ethiopia and fled the Eritrean–Ethiopian War when she was 15, eventually receiving political asylum in the Unites States. She earned her bachelor's and master's degrees as well as her PhD from Stanford University. While at Stanford, she worked as an intern at Apple making audio circuitry and later developed signal processing algorithms for the first iPad. After brief stint at Microsoft where she investigated racial bias in facial recognition software, she joined Google in 2018 to co-lead a team the ethics of artificial intelligence. However, in late 2020, her employment at Google was terminated when she refused to withdraw a research paper about the serious risks of large language model AI systems (Dr. Gebru claims that she was fired, while Google has refused to say whether she resigned or was terminated). Since leaving Google, Dr. Gebru has co-founded Black in AI, a community of Black researchers working in AI, and the Distributed Artificial Intelligence Research Institute (DAIR), a "space for independent, community-rooted AI research, free from Big Tech's pervasive influence". She has earned numerous accolades, including being named one of the world's 50 greatest leaders by Fortune Magazine in 2021 and one of Time Magazine's most influential people of 2022.

Here's the plan for this week as we wrap up Unit 7: ArrayList:

Enjoy your looong weekend, and please let me know if you have any questions!

Week 23: Monday, February 5th – Friday, February 9th

Happy Black History Month! Before I list this week's activities, I'd like to tell you about Dorothy J. Vaughan (1910–2008), the first African-American female supervisor of the National Advisory Committee for Aeronautics (NACA) who became an expert in digital computers and their applications in NASA programs. Ms. Vaughan graduated from Wilberforce University in Ohio with a degree in mathematics and started out as a math teacher. In 1943, to support our country's efforts in World War II, she joined NACA as a human "computer" who did complex calculations for engineers and scientists. She worked with computers Vera Huckel and Sara Bullock to create an algebraic methods handbook for mechanical calculating machines, and when NACA became NASA, she joined its new Analysis and Computation Division and became an expert FORTRAN programmer. Ms. Vaughan and her countless calculations supported NACA and NASA accomplishments and helped to achieve our country’s aerospace goals. Very impressive!

Here's the plan for this week as we continue Unit 7: ArrayList:
