In this article, we use evidence to describe seven key lessons from a four-year district-wide computer science implementation project between Howard University and the District of Columbia Public Schools. These lessons are: (a) Get to know the school counselors (and other key personnel); (b) Expect personnel changes and strategic reorganization within school districts; (c) Be innovative to build and maintain community; (d) Be flexible when developing instruments and curricula; (e) Maintain a firm commitment to equity; (f) Develop tiered content and prepare to make philosophical adjustments; and (g) Identify markers of sustainability. We also include original curricula materials including the Computer Science Course Evaluation and the Computational Thinking Survey. The seven lessons and curricula materials provided in this study can be used to inform the development of future computer science researcher-practitioner partnerships.

"I had just pressed the glowing submit button on my screen. After two and a half years, I finally finished my Masters in Computer Science. As the immediate thrill of being done with my coursework subsided, I had a moment of reflection. How had I gone from a high school student who routinely finished in the back of the class to graduating with a near 4.0 in my second graduate program? I went from a bottom of the barrel student to an elite performer with good study habits. Through this story, I would like to highlight the fundamentals that I find instrumental to improving your learning capabilities."

"Your smartphone is packed with sensors and miniaturized equipment. Instead of using them to snap photos or message friends, harness those instruments for the sake of science. Software can turn a phone into a mobile science laboratory, letting you make research observations, track earthquakes, study birds and stars and the elements, and even project a virtual particle accelerator. Here are some of our favorite apps for doing science on your smartphone. "

"In January 2004, NASA announced it was canceling a mission to service the Hubble Space Telescope. In light of dangers associated with the Columbia tragedy the previous year, it was considered too risky. As a result, the Hubble, lauded as one of the most influential scientific instruments of all time, would have only a few remaining years to survive. Over the following months, the plan was intensely debated. Petitions garnered thousands of signatures from members of the public. Congressional committee meetings and hearings were held. Citizens and scientists alike, inspired by the discoveries and images the telescope had produced, clearly weren't ready for the telescope's premature retirement. By that point, the Hubble had nearly fulfilled all its mission objectives since its launch in 1990. With 100,000 observations, it had measured the universe's expansion, studied planetary origins, and produced a vast trove of pictures like the iconic Deep Field (seen at the top of this piece) and Pillars of Creation, which changed the way we see our place in the universe. These images, taken for science and re-mastered by astronomers, captured the public's imagination in a way no telescope had before. "

"In India, 41km of highway road was constructed every day for the year of 2016. In the Indian government budget, it estimated the cost just for 2016 to be 19 billion USD. It would be financing any shortfall through tax-free government bonds. Computational thinking would have played an instrumental role in deciding on where the road would go through with taking into account the key hubs and may have saved the government millions, if not billions of dollars. Jeanette Wing (2012) defines computational thinking as the thought process involved in formulating a problem and expressing its solution in a way that a computer-human or machine can effectively carry out. It is the process of abstraction by; choosing the right abstractions, operating in terms of multiple layers of abstraction simulations and defining the relationships between layers guided by efficiency, correctness, and flexibility. Computational thinking can best be related to as writing software or instructionals. Every action or non-action is accounted for in the way computational artifacts are constructed. Computational thinking is great for working out a solution but there is an argument that computational thinking does not put enough emphasis on the problem itself. Design thinking, on the other hand, attempts to understand the intent or problem before looking at any solution - computational or otherwise. Design thinking attempts to identify why the problem exists in the first place before solving it. IDEO defines design thinking as the application of empathy and experimentation to arrive at innovation solutions through making decisions based on stakeholder input and evidence based research. Using the Indian roading example, a design thinker would ask, what is the intent of building the roads in the first place?"

"I am a big fan of music in the history classroom and I have created a number of Spotify Playlists for this purpose. Often this is merely to help create a calm and purposeful working atmosphere, when a bit of Chopin or Debussy sets the tone perfectly. Occasionally it's even possible to have calming instrumental music directly related to the topic in question: for example, Elgar's Cello Concerto in E Minor, which was inspired by the composer watching British troop ships heading off to France in 1914. However, some songs are better used to stoke up some energy during lessons, whilst the very best of all are historical sources in themselves, combining musical feeling with powerful lyrical content. What follows is a list of songs I regularly use in class, organised in broadly chronological order in terms of the topics they relate to, with a brief explanation of how you could make use of them with your own students. What follows is a list of 25 principal songs, but with links to others on similar themes or by similar artists, bringing the total up to over 50. If you have any other suggestions, please contact me (@russeltarr / @activehistory on Twitter) and I'd be delighted to add them to the list (as long as it isn't "We didn't start the fire" by Billy Joel. Which I admit is superb, but we all know this one, surely?)."

"Higher-level thinking has been a core value of educators for decades. We learned about it in college. We hear about it in PD. We're even evaluated on whether we're cultivating it in our classrooms: Charlotte Danielson's Framework for Teaching, a widely used instrument to measure teacher effectiveness, describes a distinguished teacher as one whose "lesson activities require high-level student thinking" (Domain 3, Component 3c). All that aside, most teachers would say they want their students to be thinking on higher levels, that if our teaching kept students at the lowest level of Bloom's Taxonomy-simply recalling information-we wouldn't be doing a very good job as teachers. And yet, when it's time to plan the learning experiences that would have our students operating on higher levels, some of us come up short. We may not have a huge arsenal of ready-to-use, high-level tasks to give our students. Instead, we often default to having students identify and define terms, label things, or answer basic recall questions. It's what we know. And we have so much content to cover, many of us might feel that there really isn't time for the higher-level stuff anyway. If this sounds anything like you, I have a suggestion: Try a curation assignment."

"Over the past five years, we have developed a computational thinking framework based upon our studies of interactive media designers. The context of our research is Scratch - a programming environment that enables young people to create their own interactive stories, games, and simulations, and then share those creations in an online community with other young programmers from around the world. By studying activity in the Scratch online community and in Scratch workshops, we have developed a definition of computational thinking that involves three key dimensions: (1) computational concepts, (2) computational practices, and (3) computational perspectives. Observation and interviews have been instrumental in helping us understand the longitudinal development of creators, with participation and project portfolios spanning weeks to several years. Workshops have been an important context for understanding the practices of the creator-in-action."

"8-year-old Kaori Misue was born without fingers. Usually, creating specialized prosthetics costs upwards of $15,000. However, thanks to a 21-year-old inventor, Misue received a prosthetic hand which has changed her life. Gino Tubaro is offering kids born without limbs the chance to receive a cheap 3D printed prosthetic. Misue's mother, Karina Misue, adds: "It was magical… The confidence it gives kids is tremendous. They're using it with pride." Tubaro's 3D printed prosthetic designs are part of the "Alternative Limbs Project", which began in his home of Argentina. The prints come in a range of designs, offering users the chance to decide what they need the prosthetic for most, whether it's playing an instrument or ping-pong. The prosthetics for kids can even be superhero themed (and shoot rubber bands)."
