Task Analysis is not only the most important component of Instructional Design but also the most often misconstrued and poorly executed. Starting with this premise these authors have developed a complete reference and instructional text on Task Analysis. The Handbook of Task Analysis Procedures fulfills three distinct purposes. As an overview of the field it presents a comprehensive collection of functions, techniques and tools that can be used in a variety of settings. Thirty-five different procedures are cataloged and described in individual chapters. Providing flowcharts and examples, it is organized to instruct the reader on how to perform these techniques. Finally all chapters have been consistently structed making it an ideal reference book. Handbook of Task Analysis Procedures is designed to help the reader select a specific task analysis technique for a particular situation. Having done this, the reader can then refer to the appropriate chapter for his chosen technique. This chapter provides a statement of purpose, an overview, and applications. It then presents a step by step description of how to use the procedure. The chapter concludes with examples, an evaluation, and a complete set of references. Designed to be used in education and by trainers in the business sector, this volume is a unique reference book. Part I provides an overview of Task Analysis and describes the variables that affect how task analysis is performed. A decision table and discussion help the reader select specific techniques. The techniques are grouped in Part II, III, and IV according to their functional similarity--learning analysis, job analysis, content analysis. Part V describes information gathering tools. This Handbook is essential for the reader who believes that competent task analysis is a vital part of instructional design.

In the field of plant analysis there is a confusing variety of methods and procedures, both for digestions and determinations. In many cases the digestion and the subsequent determination are interrelated. For example, a separate digestion is needed for trace elements in order to obtain determinable concentrations. The authors have chosen a design in which the digestion/extraction procedure is described in one chapter together with all determination procedures that may be carried out on that particular digest/extract. All the necessary information (such as standardizations) appears in appendices. As a consequence, several determination procedures are described two or three times, however, each based on a particular digestion or extraction method. Two types of determination procedure are described: manual and automated. Manual procedures are mainly used in research laboratories, whereas automated procedures are more frequently applied in routine laboratories. Both types of determinations can be used freely, provided that appropriate equipment is available. The determination procedures are only for inorganic components, usually elements. Besides, most procedures are designed to give a total content value of the element under consideration, regardless of the chemical structure in which it occurs in the plant. The Plant Analysis Manual is intended for the practicing (agricultural) chemist.
