= Berkeley Open Learning Technology (Bolt) = Bolt is a toolkit for web-based teaching and training. Its main features: * Bolt provides tools for statistically measuring and comparing the effectiveness of lessons, relative both to the entire student population and to subgroups based on demographics and other factors. * Bolt provides tools for making courses adaptive, based on student characteristics. * Bolt is based on PHP, a simple but powerful scripting language. Thus, Bolt is designed for educational contexts in which there is a constant arrival of diverse students, and in which course developers want to continually analyze and improve the effectiveness of the teaching materials.
