699.jp presents official teaching materials and product information for the TFW-AT1 inquiry tool from the “AkaDako Teaching Materials Collection.” It is not a typical live or recorded online course, but rather a set of sensor- and programming-based inquiry hardware materials designed for school classrooms. It is intended for topics such as “Use of Electricity” in sixth-grade elementary science, technology/information and measurement-control classes in junior high school, and information/inquiry courses in high school.
The tool includes more than 10 built-in measurement functions, including temperature, humidity, air pressure, brightness, distance, three-axis acceleration, tilt, voltage, and sound level. It also supports multiple charting environments, automatic input into Google Sheets, Excel downloads, and full-sensor monitoring. The programming environment uses Scratch-compatible Xcratch and Stretch3, with extensions for AI image/speech recognition, IoT, cloud databases, speech synthesis, translation, home appliance control, and smartphone notifications. The page also highlights support for expansion with more than 50 Grove-compatible sensors and actuators, making it suitable for project-based learning and maker education.
Pricing is relatively clear: one TFW-AT1 inquiry tool costs 18,000 JPY, or 19,800 JPY including tax; a three-color set costs 54,000 JPY, or 59,400 JPY including tax. The package includes the main unit, problem-solving programming cards, and a manual. Schools are advised to consult authorized retailers for procurement, and elementary schools may consider purchasing through relevant “Rishin” channels. The main text does not specify payment methods, the individual purchase process, or after-sales policies.
The main advantages are its high level of hardware integration, with no batteries, charging, or assembly required, plus a built-in USB cable, making classroom deployment relatively straightforward. Scratch compatibility lowers the programming barrier for students, and the problem-solving cards help teachers organize tasks quickly. The downside is that it is more of an equipment and teaching-materials package than a complete course: it lacks a full syllabus, lesson-hour plans, teacher training, learning assessment, and certification information. For Mac and iPad use, the Scrub browser is required; Type-C or Lightning devices may also need adapters, and the site notes potential instability when connecting some servo motors to an iPad.
It is suitable for Japanese schools conducting science experiments, measurement-control activities, introductory AI/IoT lessons, and Scratch-based project learning. It is also a good fit for maker classrooms with teacher guidance. For users in China, the site does not state whether it is accessible, nor does it provide details on cross-border payment or procurement channels, so these remain unknown. If a Chinese-language ecosystem and local purchasing are needed, micro:bit, Arduino education kits, MakeCode, Scratch, or LEGO SPIKE would be easier alternatives.
