Teachers can easily search for and sort resources by grade, subject, subcategory, and resource type.
Experimenting with Kotlin during the hackathon: Kotlin on the JVM supports true parallelism within a single process, whereas Python in the CPython implementation available to us does not, due to the global interpreter lock.
Flash animations are engaging character animations that reinforce academic skills and concepts. How did these differences slip through the cracks?
To be frank, our Python code has a lot of room for optimization within Python, so why start over in a new language? In order to allow this gradual transition, we passed down a feature flag to our client-side code that chose on a per-person basis whether to use the old Python version of the API or the new Kotlin version.
The toolkit is a great resource for teachers looking for materials to supplement their lessons or present during whole class and small group instruction, or who are simply looking for some great ideas.
Hassel was named to the inaugural class of the Aspen Teacher Leader Fellows program, designed to cultivate and support teacher leaders who are working to improve the teaching profession and student outcomes.
He is a senior research affiliate with the Center on Reinventing Public Education, and a nonresident senior fellow with Education Sector. Khan and his kindred may be able to overcome that, but it reinforces the importance of reaching more students with excellent instruction — live and online — during the 35 hours per week they are already in school.
The excellence of the teacher-in-charge will have the same enhancing and mitigating effect on digital learning as it has on every other reform tried to date. We decided to proceed with writing a Kotlin service to serve this one API, direct traffic to the new API, and compare the number of servers we needed before and after the transition.
These activities outline individual or group projects that motivate and engage students in self-directed learning. Khan and Hess are somewhat onto this, but seem to be thinking of it more as just enabling in-person teachers of any quality to engage in more interaction with the kids they have — rather than specifically to give dramatically more kids access to the best available in-person teachers.
Results Because our old Python API was running on a set of multithreaded instances virtual servers that were concurrently serving a bunch of other APIs, it was not straightforward to directly compare the cost and performance of the old version to the new one.
But there was a sense, especially on the infrastructure team, that we were sometimes being limited by our tools. In parallel, continued efforts to untangle and refactor our existing Python codebase will yield more isolated APIs that are easier to port to Kotlin if and when the time comes to do so.
An example of this was small changes in user agent parsing: But now we can choose static or dynamic typing based on a the requirements on a given piece of code. This API serves a very large number of very small requests. Hassel received his Ph. Study Island Feature Focus: We collect data such as how many times a person has attempted to solve a particular exercise and how that person navigates around the site.
Khan Academy videos help reinforce our middle and high school math lessons with brief tutorials that review specific concepts and examples. Take a look at our Formative Assessments solution page! Teacher videos feature experienced teachers who briefly talk through ways in which you can effectively address and teach specific topics in your classroom.
This is our API for recording analytics events from web clients. This gives us more flexibility to do asynchronous background processing, or to serve more requests simultaneously.
Code rewrites can often be disastrous. As technology advances, students will still need accountable adults taking responsibility for their learning. First and foremost, learning!
We wondered how much we could improve our costs if we wrote a separate service optimized for serving just this one API endpoint. To catch issues that tests may not, we also have monitoring for step changes in our key metrics that alert people to the possibility of bugs being deployed.
