Hawaiian bilingual language immersion (Kaiapuni) schools infuse curricula with place-based education to increase student connection to culture. However, stand-in teachers often lack the background and tools needed to support immersion learning, resulting in discontinuity for students in their culturally relevant education. This experience report describes a partnership between the Ka Moamoa Lab at the Georgia Institute of Technology and Ke Kula Kaiapuni 'O Pu'ohala School to design a teacher-substitute support platform via a hybrid of assets-based design methodology and emerging technology capabilities. We share insights offered by teachers and design requirements for such a platform. We also reflect on how HCI methodologies should adapt to center and respect Native Hawaiian perspectives. 

This experience report describes two years of work integrating coding with Micro:bits and Makecode into a Hawaiian immersion bilingual school setting to teach computer science (CS) skills in a place-based approach. This report highlights the collaborative partnerships and programs between a public Hawaiian immersion school, a non-profit organization that manages important cultural sites, and a university lab that develops sustainable technology. Students identified the importance of sustainability in computing by engaging with past, present, and future technologies in culturally relevant contexts. We describe ongoing work to improve the way we support students and teachers in a Hawaiian-immersion bilingual school setting. 

Hands-on computing has emerged as an exciting and accessible way to learn about computing and engineering in the physical world for students and makers of all ages. Current end-to-end approaches like Microsoft MakeCode require tethered or battery-powered devices like a micro:bit, limiting usefulness and applicability, as well as abdicating responsibility for teaching sustainable practices. Unfortunately, energy harvesting computing devices are usually only programmable by experts and require significant supporting toolchains and knowledge across multiple engineering and computing disciplines to work effectively. This paper bridges the gap between sustainable computing efforts, the maker movement, and novice-focused programming environments with MakeCode-Iceberg, a set of compiler extensions to Microsoft's open-source MakeCode project. The extensions automatically and invisibly transform user code in any language supported (Blocks, JavaScript, Python)into a version that can safely and correctly execute across intermittent power failures caused by unreliable energy harvesting. Determining where, when, and what to save in a checkpoint on limited energy, time, and hardware budget is challenging. We leverage the unique intermediate representation of the MakeCode source-to-source compiler to design and deploy various checkpointing techniques. Our approach allows us to provide, for the first time, a fully web-based and toolchain-free environment to program intermittent computing devices, making battery-free operation accessible to all. We demonstrate new use cases with multiple energy harvesters, peripherals, and application domains: including a Smart Terrarium, Step Counter, and Combination Lock. MakeCode-Iceberg provides sustainable hands-on computing opportunities to a broad audience of makers and learners, democratizing access to energy harvesting and battery-free embedded systems.
