Synopsis It introduces the classroom teacher and prospective teacher to those elements of measurement and evaluation that are essential to good teaching.  The main theme throughout the book is that the evaluation of learning plays an important role in the instructional process and that its effectiveness depends largely on the ability to construct and select tests and other evolution instruments that provide valid measures of the intended learning outcomes.  The book was designed for the introductory course in educational measurement and evaluation, at either the undergraduate or graduate level, and assumes no previous knowledge of measurement or statistics.  The writing is direct and numerous examples are used throughout the book to illustrate important concepts, instruction, instruments and procedures.  Statistical concepts are introduced only where necessary for understanding the discussion and then the emphasis is on interpretation rather than computation.  A special section on elementary statistical computations is provided for those who want to develop a minimum level of computation skill.  In addition or instead, textbook reading can be accompanied by practical project in test construction, text selection and text interpretation and the like.  In any event practical application of the material will enhance learning and contribute to competence in using measurement skills.
