The document compares the principles of authentic e-learning and cultural-historical activity theory (CHAT). Authentic e-learning aims to design instruction that is engaging and allows students to solve problems like experts in real-world contexts. CHAT examines human activity and development through social and cultural interactions. Some principles of the two frameworks align around context, collaboration and mediation, but their characterizations differ. For example, authentic e-learning contexts are adaptive while CHAT views context as transformative. Empirical research is needed to further explore contradictions between the frameworks and correctly understand their intersection.
