With the ever-increasing integration of new technologies in face-to-face instructional settings, approaches to modern language education pose numerous challenges to program evaluation. Blended Language Program Evaluation introduces an argument-based approach to guide program evaluators and stakeholders through planning, conducting, and appraising evaluation projects that result in useful outcomes leading to program improvement. Written for program evaluators and language professionals alike, the book discusses theoretical underpinnings for the proposed framework and describes the specifics of its effectuation at each of the three program levels: micro, meso, and macro levels. To illustrate the utility, flexibility, and application of the framework for evaluating blended language programs, the book presents four case studies conducted in diverse international contexts.
