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.

THE TEACHING SEQUENCE OR DIDACTIC SEQUENCE.

Imagen
The most important in Didactic Sequence are: what is didactic Sequence, What is the Relationship between didactic Sequence and Method? , How can we Structure a Didactic Sequence? , what is the purpose. First Didactic Sequence are shaped by the order in which the activities are represents a teaching Hypothesis,  there are as many Didactic Sequence as a teacher can imagine so Didactic Sequence will very in length depending on difficulty of the issues raised, the learning objective and the logic of their treatment, examples: Didactic Sequence: teaching presentation (introduction) in classroom , content study by students , students  practice (individual or group) a lot of subjects next applying  similar tasks or exercises another Didactic Sequence are promotion or emergence of cognitive conflict ( solve a problem, make an application) activate prior knowledge (dialogical interrogation) representation of new contents, exhibition, modeling, group analysis, Questio...

WHAT IS BEYOND THE COMMUNICATIVE APPROACH TO LANGUAGE TEACHING 5.6

Imagen
Throughout the history of language teaching it has often been as summed that one method is the only one time, this applies to communicative language teaching (CLT) perhaps more than to any other approach, since form the very beginning there have been a series, students are supposed to learn these items and somehow synthesize them in their minds another recently developed way of teaching is the lexical approach this words, not grammar, give meaning to language. It does not mean that teachers should not teach grammar, also a methods that been developed especially in USA  is content Based Instruction (CBI) this methods come from immersion education English for specific purpose commutative language teaching has started to decline , so other methods and approaches are already being tried and used in language classroom next the teacher use a lot of methods for students but teacher use variety ideas and methods teaching and learning become challenging and fulfilling experiences.
