California educators are considering a new mathematics instruction framework that purposefully de-emphasizes calculus, though calculus is required or heavily encouraged for applicants to several of the nation’s top colleges and universities.
The framework, which is still under consideration, proposes eliminating advanced math classes in middle school and eliminating a “push to calculus in grade twelve,” which it calls “misguided.”
The framework prioritizes equity and instructs teachers to “teach toward social justice.” It argues against beginning advanced math classes in middle school, saying, “Many students, parents, and teachers encourage acceleration in grade eight (or sooner in some cases) because of an incorrect conclusion that Calculus is an important high-school goal.”
Luminar and Volvo Cars release of comprehensive lidar dataset; 250m range
Luminar Technologies, Inc., a provider of automotive lidar hardware and software technology, and Volvo Cars released a curated dataset called Cirrus containing unique long range lidar data from Volvo Cars’ test and data collection fleet. This curated dataset is being opened to industry developers and researchers in order to aid and further advancements for safe self-driving.
The Cirrus dataset contains 6,285 pairs of RGB, lidar Gaussian, and lidar Uniform frames. Cirrus has been annotated for eight object categories across the entire 250-meter lidar effective range. It includes both high-speed highway and low-speed urban-road scenarios. All images have gone through an anonymization process blurring faces and license plates to eliminate personally identifiable information.
