Task analysis

Summary

First the most important of Task Analysis is identifying sequential steps of performance job to reach a goal. The conduct a Task Analysis we break down a task small sub-task produces a result that help to reach a goal or General Objective so it is important to recognize the cognitive difficulties that every subtask or activity requires to be perform, thus we can put those activities into a hierarchy from

General to specific. What a user is required to do in terms of actions and/or cognitive processes to achieve a task. A detailed task analysis can be conducted to understand the current system and the information flows within it, Provides knowledge of the tasks that the user wishes to perform. Thus it is a reference against which the value of the system functions and features can be tested.

 Second the Bloom mention three levels factual, procedural, Metacognitive. Factual is basic elements students must know, Procedural is how to do something methods of inquiry and criteria for using skills, algorithms, techniques, and methods, Metacognitive is knowledge of cognition general as well as awareness and knowledge of one own cognition, comprehension, application, Analysis, Synthesis

And evaluation. Third the task decomposition can be carried out using the following stages: 1. Identify the task to be analysed.2. Break this down into between 4 and 8 subtasks. These subtasks should be specified in terms of objectives and, between them, should cover the whole area of interest.3. Draw the subtasks as a layered diagram ensuring that it is complete.4. Decide upon the level of detail into which to

 Decompose. Making a conscious decision at this stage will ensure that all the subtask decompositions are treated consistently. It may be decided that the decomposition should continue until flows are more easily represented as a task flow diagram.5. Continue the decomposition process, ensuring that the decompositions and numbering are consistent. It is usually helpful to produce 

Written account as well as the decomposition diagram.6. Present the analysis to someone else who has not been involved in the decomposition but who knows the tasks well enough to check for consistency.as a conclusion Task Analysis is very important methods and technique  in the learning to students.
