Norris "], "item_description" : "This book explores the notion of validity evaluation as a means for helping educators to ensure the utility and worth of their assessment practices. With a particular focus on foreign language testing, the author challenges assessment traditions and argues for a fundamental reconceptualization of assessments and their validation in language teaching and other educational settings. Following a critical review of test validity standards and methods within educational measurement, the author then proposes a comprehensive alternative approach to validation based upon program evaluation methodology. A report of a multi-year case study completes the volume, providing in-depth analyses of how validity evaluation methods were applied by foreign language educators in meeting the assessment needs of a German program at a US university.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/3/63/154/946/3631549466_b.jpg", "price_data" : { "retail_price" : "101.10", "online_price" : "101.10", "our_price" : "101.10", "club_price" : "101.10", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
