Abstract

The process is described for developing a prioritized list of competencies in the materials area for materials technicians and general technicians along with the results of that process. A total list of 397 competencies was developed and rated by 36 materials professionals from a diverse array of industries in four U.S. cities; Seattle, Los Angeles, Detroit, and Cleveland. The full list was then divided into 75 categories and aggregated results for both the full list and the ’75 list’ were developed that give the relative importance of the competencies. Covered were a) general technical, employability, and professionalism skills, b) mathematics, chemical science, and physical science skills, c) fundamentals of materials technology and materials testing, d) several classes of materials and their processing, e) manufacturing processes, tooling, manufacturing operations, quality management, and f) the effects of defects and manufacturing variations on the behavior and mechanical properties of materials. The results are being used to develop a materials resource center for educational materials to assist educators in associate degree engineering technology programs and in lower division engineering programs.

1. Introduction

This report documents the process used to develop a list of competencies in the area of materials technology for technicians studying for the associate degree. The results are to be used by the project staff to develop a database of educational materials called the National Resource Center for Materials Technology Education, referred to as MaterEd.

This work is part of a larger project funded by the Advanced Technological Education Program of the National Science Foundation, grant 0501475. Edmonds Community College in Lynnwood, Washington is the fiscal agent and lead institution for this project.

The competency development process was planned and executed by the author of this paper in conjunction with Dr. Tom Stoebe, project director, Ms. Mel Cossette, project principal investigator, and other project staff members.

2. Goals of the Competency List Development Process

The primary overall goal of the MaterEd project is to provide college educators with a robust and easily accessible database of educational materials that will aid them in providing effective courses and programs in the materials field, with the greatest focus on associate degree programs and the lower division part of bachelor degree programs in engineering technology and engineering.

It is considered essential that the educational materials cover the materials competencies that industry professionals from a variety of industry types across the United States consider to be the most important and desirable.

The list of competencies was to be organized in a manner that would facilitate the identification and acquisition of appropriate, high-quality educational materials from many sources and aid in the process of posting them on a website for easy access and use by educators.

3. Procedure

The main aspects of the procedure used to develop the list of competencies are:

1) During the proposal development process, members of the project staff surveyed a variety of industry professionals to gain insight into the types of competencies that they consider to be important for technicians to have to perform well in their industries.

2) The author of this report was engaged by the project staff to use this preliminary information to develop a process of finalizing the list of prioritized competencies.

3) The project director arranged for four focus groups to be held in four geographically dispersed and industrially diverse areas of the country; Seattle, Los Angeles, Detroit, and Cleveland.

4) In cooperation with partners in the areas where the focus groups were conducted, 35 industry professionals with knowledge and experience in a variety of materials specialties were enlisted as volunteers to comment of the list of competencies and to rate them as to their importance. See Appendix A for a list of focus group participants.

5) The focus group participants were asked to rate all of the competencies as they related to their own industry and organization. Two ratings were requested;

2

a) For the Materials Technician whose primary job tasks relate directly with the processing or testing of materials.

b) For the General Technician engaged in technical work but who does not have direct responsibility for materials processing.

6) The focus group participants were given a rating scale as follows:

a) 1 = Vital

b) 2 = Important

c) 3 = Desirable but not critical

d) 4 = Not important

7) The author of this report, with guidance and input from the project director, created an initial list of 250 competencies that were presented to all focus groups to start discussion and to serve as a base on which to build a more robust list.

a) The initial list of competencies included 19 major categories

i) Four were general technical, employability, and professionalism skills

ii) Three were mathematics, chemical science, and physical science skills

iii) Two dealt with fundamentals of materials technology and materials testing

iv) Seven related to different classes of materials and their processing. These classes contained nine sub-categories to break out specific types of materials.

v) Three related to manufacturing processes, tooling, and their effects on the mechanical properties of materials

8) As each focus group completed the rating of the initial list, the members were asked to propose additional competencies that are pertinent to their industries. They then rated those added competencies using the same scale and rating process.

a) A total of 147 competencies were added by the focus group participants

b) The added competencies resulted in one additional category of materials and one additional main category dealing with manufacturing operations and quality management

9) As the cycle of four focus groups was completed, those added competencies developed by previous groups were presented to the later groups along with the initial list.

10) At the end of the cycle of four focus groups, earlier groups were presented the opportunity to rate the competencies added by the later groups.

11) The author of this report compiled all results of the ratings from each focus group, including both the initial list and the added competencies.

12) The author then blended the results of the ratings from all four focus groups together.

13) The author merged the added competencies with the initial set with some editing for consistency of wording and terminology and eliminating duplications. The total list included 397 competencies.

3

14) The merged set of competencies was sorted by the aggregate score of all focus group participants. The sorting was done within the categories and sub-categories included in the initial list plus those added by the focus group participants.

15) Because the complete list of 397 competencies was deemed cumbersome to manage in relation to the following tasks of the project, additional sub-categories were created to aggregate more detailed competencies. The result was a list of 75 category groups, referred to as the ’75 List’ in this report.

16) For each category in the 75 List, the mean rating and the range of ratings for all competencies within that group were computed for both the General Technician ratings and the Materials Technician ratings. This gives users of this list an indication of the relative importance of these aggregated categories.

17) To aid users to visualize the general order of importance (prioritization) of the compiled results, a color scheme was devised as described next. (See the discussion to follow)

a) Green: Mean scores from 1.000 to 2.200 (spanning ‘Vital’ and ‘Important’), referred to in this report as simply ‘Important’.

b) Blue: Mean scores greater than 2.200 up to and including 3.200 (spanning from above ‘Important’ to ‘Desirable’), referred to as simply ‘Desirable’.

c) Red: Mean scores greater than 3.200 up to 4.000 (spanning above ‘Desirable’ toward ‘Not important’), referred to as simply ‘Less important’.

18) A spread sheet of final results is presented in Appendix B.

Discussion of the Green, Blue, and Red Priority Ranges

The specification for the prioritizing ranges of scores listed in item 17 above was a qualitative judgment made by the author to indicate the relative priority of the competencies and to give a visual cue for the scores compared with the rating scale listed in item 6. Because the score for each of the 397 competencies is a weighted average of many individual ratings, the values cover a wide range from approximately 1.10 to 3.60. It was noted that, except for a few competencies, there were relatively few individual ratings of 1 (vital) but many rating of 2 (Important). It was therefore decided to make the highest priority range (green) to span from the lowest range of ratings, 1.000 to 2.200, slightly above the ‘Important’ rating and to refer to them simply as ‘Important’.

Similarly, the rating of 3 (Desirable, not critical) indicates a generally positive rating and was frequently chosen by the raters, while the rating of 4 (Not important) was used much less often. Therefore, it was decided to use 2.201 to 3.200 for the Blue range. The selection of the upper limit for this range (3.200) was made after perusing the effect of selecting either 3.000 or 3.100 instead. It was found that selecting either of these lower values would eliminate several competencies from being considered in this middle range, particularly for the General Technician (GT) set of scores. For example, most of the competencies for GT related to ‘aluminum’ are between 3.000 and 3.200 and would be pushed to the Red range if the lower limits were used. It was judged that the reason for this relatively high score (relatively low importance) was due to the types of materials used on a regular basis by the particular focus group members involved, and that aluminum is, in fact, a very important material in many industries. This middle rating group is referred to as ‘Desirable’.

4

Finally, the Red range (above 3.200 to 4.000) indicates that a significant number of the raters felt that the competency was ‘Not important’, while some rated it ‘Desirable’. This upper rating group is referred to as ‘Less important’.

A total of 27 individual competencies are in the Red range with 25 of them for GT scores and only two for MT. This seems appropriate because the list of competencies was tailored to encompass a comprehensive array of materials-related competencies of which virtually all were expected to be generally desirable for Materials Technicians. However, some of the competencies are so detailed and materials processing-specific that they would not be expected of General Technicians.

A further effect of using an upper limit of the Blue range anywhere from 3.000 to under 3.200 is that many more of the competency groups in the reduced ’75-list’ would appear in the Red range and would be considered to be ‘Less important’. This, again, shows up among the specific materials and processes competencies for aluminum as well as cast iron, copper, zinc, nickel alloys, and ceramics.

4. Final List of Competencies

Appendix B presents the results of the process described in Section 3 of this report.

The best way to view the results is to use the Excel spreadsheet file, ‘Competency ratings-Report’, that permits navigation among the following four worksheets and viewing the color coded ratings.

Worksheet 1: ‘Explanations of worksheets’ – Describes the contents and organization of the other three worksheets

Worksheet 2: ’75 List-Major categories’ – The list of 75 categories of competencies, the mean of the ratings of the individual competencies that make up each category, and the range of scores (Minimum and Maximum) for all items in the category, for both General Technicians (GT) and Materials Technicians (MT). The competencies that make up each category can be viewed in Worksheets 3 and 4.

Worksheet 3: ‘Full list-GT Sort’ – All competencies, organized into the 75 categories, and sorted by the ratings for General Technicians.

Worksheet 4: ‘Full list-MT Sort’ – All competencies, organized into the 75 categories, and sorted by the ratings for Materials Technicians.

The four worksheets are included in Appendix B. If color copying was used, the color coding of the results can be viewed. However, if black-and-white copying was used, the color fields show as varying shades of grey.

3. A total of 31 sub-categories of competencies were rated in the ‘Desirable’ range (2.201 to 3.200, Blue) for Materials Technicians.

4. There were no sub-categories of competencies rated in the ‘Less important’ range (>3.200, Red) for Materials Technicians.

5. A total of 58 sub-categories of competencies were rated in the ‘Desirable’ range (2.201 to 3.200, Blue) for General Technicians.

6. A total of six sub-categories of competencies rated in the ‘Less important’ range (>3.200, Red) for General Technicians.

7. In summary, the distribution of composite ratings for the 75 sub-categories for General Technicians and Materials Technicians is listed below.

a. Important (score 2.200; Green) GT: 11 MT: 44

b. Desirable (2.201 to 3.200, Blue) GT: 58 MT: 31

c. Less important (>3.200, Red) GT: 6 MT: 0

Observations

1. The rating system appeared to be appropriate and useful for gaining feedback from the industrial professionals on the relative importance of the many competencies related to the materials technology field.

2. Focus group participants in general were diligent in providing their ratings and in proposing competencies to be added to the total list.

3. The focus group members represented a wide range of industry types including aerospace, composite materials processing, metals processing, automotive, materials testing, failure analysis, basic materials production, plastics processing, MEMS/NANO materials, and materials education.

4. There were significant, although not surprising, differences among raters of certain topics based on their involvement in that topic. For example:

a. Those working with composite materials tended to rate composites-related topics more important than those working primarily in metals processing.

b. Those working with plastics tended to rate plastics-related topics more important.

c. Ratings for most materials and processes competencies tended to be significantly more toward ‘Important’ for Materials Technicians and more toward ‘Desirable’ for General Technicians.

5. The focus group participants were asked to rate the competencies in relation to their perceived needs for technicians in their own organizations. This likely precipitated the differences and polarization of responses as mentioned in item 4 above. For example, raters who worked with organizations that dealt with only plastics, composites, ceramics, or glass, typically rated some competencies dealing with metals far toward the ‘Not important’ end of the scale. However, if the question was presented more broadly, say, “Rate the competencies as to their importance in a variety of product-producing industries,” they would have been

7

more likely to rate the metals-related competencies more toward the ‘Important’ end of the scale.

6. Basic employability skills (Category 0.000), Computer skills (Category 3.000), Teamwork and Professionalism (Category 4.000), and Quality management (part of Category 19.000) were generally rated ‘Important’ for both General Technicians and Materials Technicians. Exceptions include ‘planning meetings’ and ‘globalism’ issues.

7. Most competencies dealing with the relationships between processing variables, manufacturing variation, quality, material properties, and defects were rated ‘Important’ for both General Technicians and Materials Technicians.

8. It is the opinion of the author of this report that many of the raters in the focus groups exhibited rather low expectations of technicians with regard to analytical, mathematical, chemical, and physical science competencies, particularly for the General Technicians. Examples of the bases for this observation are:

a. Only basic mathematics fundamentals and simple concepts of area, volume, angles, triangles, mean, median, and standard deviation were rated ‘Important’, whereas trigonometry, algebra, slope, rate of change, functions, and statistical analysis were rated more toward the ‘Desirable’ end of the scale. See category 2.000.

b. Virtually all of the Chemistry fundamentals competencies were rated toward ‘Desirable’ for General Technicians although they were rated ‘Important’ for Materials Technicians. See Category 5.000.

c. Almost all of the Physical Science skills (Category 6.000) were rated toward the ’Desirable’ end of the scale for both General Technicians and Materials Technicians.

NATIONAL RESOURCE CENTER FOR MATERIALS TECHNOLOGY EDUCATIONExplanation of the data for core competencies in materials education

shown on the other three worksheets in this workbook

The other three worksheets summarize the results of ratings of a list of core competencies in the materials field that should be acquired by both materials technicians and general technicians. Materials Technicians (MT) are those whose primary job tasks relate to the testing or processing of materials in a laboratory or production situation General Technicians (GT) are those whose primary job tasks concern product development,design, product performance testing, manufacturing, production and similar functions but who do not have direct responsibility for the properties and behavior of materials The two worksheets labeled 'Full List-GT Sort' and 'Full List-MT Sort' each contain a totalof 397 individual competencies that were proposed by the project team and members offour focus groups of industrial professionals from a variety of industries and materials fields. Each of the 397 competencies were rated by the focus group participants using the scale shownat the top of the sheets. The weighted-average scores for each competency were then separatedinto three colored ranges according to the 'Color Code' shown at the upper right of the sheet.Green color indicates the most important competencies with scores from 1.000 to 2.200Blue color indicates desirable competencies with scores between 2.201 and 3.200Red color indicates less desirable competencies with scores greater than 3.200 The competencies in each category were then sorted by GT Score or MT Score as indicatedby the name of the worksheet. In the full list, the competencies were subdivided into 75 categories to facilitate the use of the list for acquiring educational materials for a database that is designed for use by educatorsin associate degree programs in engineering technology and lower division engineering programs. The worksheet labeled '75 List-Major Competencies' contains only the 75 categories describedabove with the following information:1. The number of individual competencies that make up each category; 'No. of items'2. The mean of the scores for all of the items in the category for both GT and MT3. The range of the scores (MIN and MAX) for all items in the category for both GT and MT
