Identification of Quality Characteristics for Technology Education Programs: A North Carolina Case Study
Aaron C. Clark and Robert E. Wenig
Since its beginning, technology education has consistently pursued quality outcomes in course offerings. Especially during the past 25 years, the process of establishing standards, or outcomes, has been a major area of focus at both the national and state levels (Dugger, 1988). After interviewing North Carolina State Department of Public Instruction state officials, it was found that North Carolina had not identified indicators of quality that could be used to assess whether technology education programs throughout the state are meeting statewide curriculum goals and objectives. The identification of such quality indicators and the development of a correlated check sheet was the purpose of this study.
Program quality has been a concern for practitioners within technology education. However, what constitutes the elements of quality has not been adequately investigated. For example, Henak (1992) declared that quality learning in a technology education program comes from the content, learning process, experiences, and growth opportunities offered to students.
The problem of educational quality and its assessment extends to the whole of education. According to the Education Commission of the States (1992), even though there have been many attempts to develop educational standards, new information on assessing the quality of education provided in schools, districts, and states is lacking. The Federal Coordinating Council of Science, Engineering, and Technology (1993) added that an evaluation process is needed in each state to analyze programs so that questions about the quality of a program can be answered. Further, if responsible change efforts are to be made to establish quality in a technology curriculum, they must include a structure for an objective and critical assessment of each program in order to establish benchmarks for the process (Dyrenfurth, Custer, Loepp, Barnes, Iley, & Boyt, 1993). Many states in addition to North Carolina are working towards setting criteria for assessing quality within technology programs. If a state is to grow and develop better course offerings within its technology education programs, more research is needed. Professionals in technology education throughout North Carolina felt that a benchmarking process was needed and it should be directly linked to an assessment strategy. Secondarily, the results of this study would also be used in establishing criteria for North Carolina's "Governor's Quality Leadership Award" in education, a goal for all educational programs within the state.
The Delphi technique for achieving consensus among experts was determined to be the best research method for the stated purpose of this study. Volk (1993) used the Delphi method for acquiring consensus on technology education curriculum development and Dalkey (1972) suggested the Delphi technique as a means for decision-making through the use of expert judgement. Procedures used for conducting this particular Delphi study were developed from experts on the methodology (e.g., Delbecq, Van de Ven, & Gustafson, 1986; Linstone & Turoff, 1975; Meyer & Booker, 1990). From the literature, it was determined that a four round Delphi process would be used.
The members of the panel of experts were selected by soliciting recom-mendations from administrators responsible for technology education, technology teacher educators, and personnel from the North Carolina State Department of Public Instruction. Individuals with the highest number of recommendations were selected to serve on the panel of experts. The resultant panel totaled 19 and consisted of 15 technology teachers, three vocational directors, and one technology teacher educator. This number was proportional to the total number of individuals within the state who serve in these respective positions.
Next, a review panel of three members was randomly selected from a list of those not selected to be on the panel of experts. The purpose of the review panel was to review and approve each instrument used in the study. This was done to reduce bias that might occur as a result of modifications made between rounds (Linstone & Turoff, 1975; Meyer & Booker, 1990). The format for the initial instrument was developed by reviewing examples from other Delphi studies (Meyer & Booker, 1990; Volk, 1993). The categories and quality indicators were identified principally from a list of similar items developed by the Maryland State Department of Education (1995).
Table 1 is a descriptive summary of the panel members and the geographic regions they represented. The population in the state is nearly equally distributed among three telephone area codes and the respondents nearly equally repre-sented these regions. Nearly two thirds taught at the high school level. For eight of the panel members, the baccalaureate was the highest degree held while ten held a master's degree or higher. One respondent had not earned a degree. Table 2 reports information about the education experience of the panel members. The average years of teaching experience was 11 with a range of zero to 28 years.

The initial instrument, once approved by the three-member review panel, was sent to the expert panel members. This represented Round One of the study. Panel members were allowed to edit the indicators and categories and add new ones. Those that were accepted by the majority of the panel members were retained. Similar items were combined and redundant items were eliminated. Once approved by the review panel, the resulting instrument consisted of 47 indicators of quality for technology education programs across eight categories.
Round two of the Delphi process involved having the panel of experts rate the quality indicators and categories identified in Round One. The process described by Meyer and Booker (1990) was followed. This involved the use of a Likert-type scale ranging from one to five. A value of one represented a very poor indicator of quality, not considered appropriate for any technology education program. A rating of two represented a poor indicator of quality, one that 49% or fewer of the programs should meet. A value of three represented a fair indicator of quality, one that was appropriate for 51 percent or more for technology education programs within the state. A rating of four represented a good indicator of quality, one that 75 percent or more technology education programs should meet. Five represented an excellent indicator of quality, one that all technology education programs in the state should meet.

Using standard Delphi procedures, a mean cutoff value of 3.01 was used on the Likert-type scale responses. Quality indicators with a mean value of 3.01 or above were retained for Round Three and the others were discarded. It was thereby determined that the remaining indicators were appropriate for 51 percent or more of technology education programs within the state. All the categories were retained.
A One Factor Repeated Measures Analysis of Variance (ANOVA) was used to determine if one particular category was dominant over other categories according to a procedure suggested by Agresti & Finalay (1986). No significant differences were found among the categories. These data are shown in Table 4.
In Round Three of the study, the panel of experts were asked to rank order the quality indicators within each of the eight categories (Meyer & Booker, 1990). Sixteen of the original 19 members of the expert panel responded to this round within the established time period. No new quality indicators were suggested in this round but they did suggest six modifications. As with previous rounds, these suggestions were approved by the review panel.

A series of Spearman correlation coefficients was calculated between the ratings of the quality indicators from Round Two compared to rankings determined in Round Three (Gibbon 1976). This statistical process was designed to reveal the relationship between each category and its corresponding indicators. The indicators in Round Two ranged from 1 (low) to 5 (high) while the rankings within each category went in the opposite direction (1 being the highest rank). Thus, a high negative correlation was an indicator of consensus between the two rounds.
The Facilities/ Equipment/Materials Category had a low negative correlation coefficient of minus .18 and the Public Relations category had a positive correlation coefficient of plus .44. These two categories, with their indicators, did not indicate consensus. However, the overall scores combined together had a moderate negative correlation coefficient of minus .40. This suggested that consensus was being achieved between rounds two and three overall. Suggested modifications from both panels were made to indicators from this round and incorporated into the fourth and final round. These data are shown in column two of Table 5.
The Spearman's correlation coefficient was also calculated between the ranks and medians for Round Three. A positive high correlation would show that no outliers (effects of one or more extreme scores) were influencing the consensus reaching process for the indicators in this round. Such high positive correlations were found for all of the categories. These data are shown in column three of Table 5.
In the end, indicators that ranked in the upper 50 percent for a category were retained and the others were discarded. This reduced the indicators to a useable number and retained only those most likely to reach consensus in the final round.
Delphi Round Four, the final round, was intended to gain the final approval of the quality indicators from the panel of experts. All but two of the panel members responded by the specified date. Each panel member was asked to indicate whether they accepted or rejected each of the quality indicators that resulted from Round Three. No suggestions for changes to the items were permitted. Once these data were collected, the indicators were placed in a contingency table.

Using the Delphi technique, a panel of experts within the state of North Carolina reached consensus on 25 quality indicators for technology education. Three major conclusions were drawn from the information collected from this study. First, the quality indicators listed in the findings for this study were developed for technology education programs in North Carolina, but most could be used for other programs that utilize laboratory instruction. The researchers for this study feel that since expert panel members were asked to write indicators general to all technology programs within the state that each indicator could easily be articulated into other program areas related to industrial or vocational education.
Second, the final listing of quality indicators are similar to those listed in Maryland's (1995) list of quality indicators. The 25 indicators found within this study cover the same topic areas as indicated within the Maryland listing of quality indicators. Major differences between the two lists are as follows. First, Maryland has developed hundreds of indicators and most are directly related to specific content in technology education. Maryland used a team of technology education professionals to assess program quality for schools within the state. Indicators found within this study are fewer in number and not as specific in curriculum content areas. Also, these indicators were written for school administrators with little or no background in technology education to use for program assessment.
Finally, major categories found within the study directly mirror eight of the ten categories for standards used in previous standards projects (Dugger, 1985). The researchers for this study did not pursue why expert panel members did not include categories for evaluation process and support systems. Also, the study with all categories and indicators solicited from the experts directly reflect those major areas and findings associated with the Technology for all Americans Project (1995). This reflection illustrates to the researchers that the establishment of standards and the development of quality indicators can coincide with each other and therefore, one can identify quality characteristics for programs through the establishment of standards for that same program. This process of combining the two areas together will allow technology education professionals to establish needed benchmarks for programs as we teach our students to learn to live in a technical world.
