Example:Task Analysis
„Automotive Service“In regard to these examples, workers in the sector of automotive service have to be able to
plan full and complex work processes supported by book- and intranet- based informations;
execute their own quality management while repairing (a lot of time and costs for remounting and mounting);
plan task-oriented diagnostic processes using complex tools and intranet- based diagnostic routines (combining routines to a successfull fault finding);
be open-minded for new mechatronic systems, their function in itself and in the car network,
combine their experience with the actual working task / failure-function.

Competence (or competency) is the ability of an individual to
perform a job properly. A competency is a set of defined
behaviours that provide a structured guide enabling the
identification, evaluation and development of the behaviours in
individual employees. (Lundberg 1970)

Generalization:Competence Development
using Case Studies
? Actual problems designing case-study oriented learning situations: (see also the „Lernfeld-Discussion“ in Germany):
? Didactical Question I: What is a good case study? (Refer to the problems in the MBA-Economic-Schools);
? Didactical Question II: What is a good sequence of case studies for the students ? (Refer to the Theories of Havinghurst, Dreyfus/Dreyfus, Polyani - Neuweg);
?Are the students able to accept their new role as „self-accountable“ learner? (or: How can the teacher transfer this idea to the students?)
? Are the teachers able to accept and to fulfill their role as coach ? (Teachers understand themselves as instructors!)

Competence-Oriented
Teacher Training
Main Question:
How has a teacher to be trained to identify study cases, to create developing tasks and to coach situated learning?
General answers (methodology oriented):
Teachers have to learn to teach by doing. (Mayr 2006)
Teacher education has to integrate practical periods. (Oser 2003)
Teacher work needs implied knowledge generated by experience. (Neuweg 2002)
Teacher work has to focus on the planning, implementation and reflection of teacher-units tailored to exemplary working tasks

Competence-Oriented

2 Organize (vocationally scientific-oriented) analyses of work-processes
3 Working didactically synthesizing (instead of reducing)
Development of tasks: Define workable and internally differentiated working tasks 4 Designing of failure-based tasks in keeping
with the learner 5 Preparation of teaching-units down to the
last detail Implementation : Offer coaching for the students; Allow for mistakes and moderate internal reviews of the student groups, offer technical and manual assistance; moderate internal and external processes of reflection

Module-System„Automotive Service“
University of WuppertalAim of the TT-TVET-modules:Teachers have to be able to create module-conform units with learning tasks, which gain more and more complexity.
For example:
Low complexity:
Controlling mass air flow sensor
by using multimeter
Teachers have to prepare, how
• students can learn to read connecting plans (identifying the pins);
• they explain to the students the use of a multimeter (measuring voltage, resistance);
• they can present examples to get across the difference between a functionable and a disfunctionable flow sensor (while engine is running, creating failure codes).

For example:
Middle complexity:
Teachers have to prepare, how
• students can understand the method of operation of a CAN-BUS and the differences between HIGH and LOW-CAN.;
• they explain to the students the use of standard oscilloscope like Fluke;
• the students can control the CAN-BUS-System to locate the possibility of a frame fault.

For example:
High complexity:
Teachers have to prepare, how
• students can work with the oscilloscope in a high-voltage-system;
• they can simulate failures (spark -plug, ignition distributor, preresistor, ignition-cable) without destroying subsystems like catalyst, lambda oxygen sensor.) ;
• they can explain to the students the use of the ranges of the oscilloscope;
• they can teach to analyze the measuring result.
