After the break, Dr. Siva introduced us to Task Analysis which is essential for success in instructional design. And the articles of Johassen, Tessmer and Hannum were discussed. According to the authors, �task analysis is a process of analyzing and articulating the kind of learning that you expect the learners to know how to perform�. From this statement, the designer should take Task Analysis into account before designing any systems when task analysis determines what must be learned to achieve the goals. Functions of task analysis include classifying task as learning outcomes, inventorying task, selecting tasks, decomposing task, sequencing tasks and task components, and classifying learning outcomes.
The authors further add Precursor-Action-Result-Interpretation (PARI), which is a system of task analysis to analyze the systems knowledge, procedural knowledge, and strategic knowledge required to solve problems in situated, real world settings. This analysis helps the designer prepare instruction to solve problems. And another analysis which is helpful for the designer is a technique called the Fault Tree Analysis, which is to improve the likelihood of success of system by identifying and quantifying the most probable causes for failure of the systems.
