Knowledge- related learning activities are brought to

27、a close with the trainees successful completion of a related information test (formative testing). Performance-related learning activities provide the instructor with a means by which to guide the trainee in attaining the objective. Utilizing the now-acquired technical information to guide his or he

28、r actions, the trainee receives a demonstration of the objective, practices performing it until an acceptable level of skill and confidence is gained, and takes a performance test (i.e. workmanship qualifications) of the same to confirm mastery of the objective. Other performance- related activities

29、 may be included in the basic sequence, but the demonstration-practice-performance trilogy is fundamental to ordering performance-related activities. Workmanship Qualification: A practical application test with elements that include drawing interpretation, fabrication, and welding symbol interpretat

30、ion. The test is evaluated in three stages and each stage must be completed correctly before moving to the next. The first stage is the preparation of a bill of materials in U. S. customary units of measure, then conversion of those units of measure to SI metric units. The first stage measures drawi

31、ng interpretation and basic math skills. Upon successful completion of stage one, the trainee fabricates and assembles the weldment. The second stage measures fabrication skills. Upon successful completion of the second stage, the trainee welds the assembly according to welding symbol information. T

32、he final stage measures a trainees ability to interpret welding symbol information and use of manipulative skills. All stages of testing are evaluated using visual examination criteria. Workmanship qualifications are summative tests and may be conducted at any time during training, once the trainee

33、has completed skills training for the welding and cutting processes specified. (Refer to Figures 2 through 6.) Closed Book Examination: A practical knowledge test for welding related knowledge. This examination will measure the trainees knowledge, comprehension and application of major subject matte

34、r concepts from classroom instruction. This summative test is administered at the end of the training cycle, before standard performance qualification. Performance Qualification: A practical application test of manipulative skills using all arc welding processes required by AWS QC 11, Specification

35、for the Qualification and Certijication for Level II - Advanced Welders. Performance is measured using visual examination and bend test criteria. This summative test is conducted at the end of the training cycle. The trainee shall pass the closed book examination before taking this set of tests. (Re

36、fer to Figure 7). Participating Organizations may elect to use, or become, AWS Accredited Test Facilities under the requirements of AWS QC4, Standardfor Accreditation of Test Facilities for AWS Certified Welder Program and administer performance qualifications, then certify advanced welders accordin

37、g to the requirements of AWS QC7, Standard for AWS Certified Welders and section 4. Optional Welder Qualification - AWS QC7 - Certified Welders of this guide. STDeAWS EG3-0-ENGL B99b 07842b5 05L8020 702 16 3.1.3 Curriculum Implementation. 3.1.3.1 Review. Participating Organizations shall review part

38、 3.2 Competency-Based Program Outline (all inclusive) and 3.3 learning Modules (all inclusive), prior to the introduction of the curriculum into the training cycle. Note: The Competency-Based Program Outline should not be construed as the steps necessary to administer the curriculum. It, as the titl

39、e implies, is an outline that may be used to quickly identi! a point in training. The Learning Modules are the heart of the curriculum and contain suflcient information for instructors to deliver the training and evaluate a tminees performance. Learning Modules include course title, learning objecti

40、ves, pe$ormance conditions, desired behaviol; evaluation criteria and learning activities. 3.1.3.2 Verification. Participating Organizations shall ensure that their existing or newly developed curriculum is in compliance with all AWS documents specified in part 3.3 learning Modules. Verification sha

41、ll be made in writing in accordance with AWS QCl 1 , Specijcation for the Qualification and Certijcation for Level II -Advanced Welders. 3.1.3.3 Lesson Plan Development. Participating Organizations shall develop appropriate lesson plans that include each learning objective and the learning activitie

42、s specified for each course or unit within a course. (Refer to 3.3 Learning Modules.) Note: Not all learning objectives are stand alone in terms of instruction. Some are delivered through a minimum period of instruction and reinforced throughout the training cycle. Determination of stand alone or co

43、ntinuous reinforcement is identijed in the evaluation criteria for each learning objective. 3.1.3.4 Delivery. It is the sole responsibility of a Participating Organization to determine sequencing of instruction. However, Participating Organizations shall deliver training in accordance with the learn

44、ing objectives and learning activities detailed in 3.3 Learning Modules. 3.1.3.5 Testing. Participating Organizations shall develop and administer appropriate formative tests during and after the completion of classroom instruction. Summative testing for workmanship qualification, (see Figures 2 thr

45、ough ), should be administered at the end of training in each applicable welding or cutting process. Workmanship qualifications must be administered prior to summative testing for practical knowledge and performance qualification. Summative testing for practical knowledge, and performance qualificat

46、ion (see Figur:. 7), shall be administered at the end of the training cycle in accordance with the requirements of AWS QCl 1, Specification for the Qualification and Certijcation for Level II -Advanced Welders. Participating organizations electing to use the QC7 optjnn Qf AWS QCll may substitute any

47、 workmanship or performance qualification test detailed in 3 J Learning Modules for the applicable welder performance qualification test detailed in section 4. Opt;?flal Welder Qualification - AWS QC7 - Certified Welders. When an optional QC7 performance qualification test is substituted, it shall n

48、ot be necessary to duplicate the applicable workmanship or performance qualification test from 3.3 learning Modules of this guide. 3.1.3.6 Record Keeping. Participating Organizations shall develop appropriate records that track each trainees achievements. In addition, appropriate records shall be de

49、veloped so that trainees may keep a self-record of achievement. See Annex E.
