RT Unpublished Material DB /z-wcorg/ DS http://worldcat.org ID 234315641 LA English T1 Papers of John V. McMillin II, A1 McMillin, John V., YR 1952 AB The Papers of John V. McMillin II primarily chronicle developments at the Measurement Research Center (MRC), which was founded in 1952 by Prof. Everett F. Lindquist of the University of Iowa College of Education. Prof. Lindquist pioneered the design and use of standardized tests in American public schools, beginning in the late 1920's. By 1953, he and his staff developed an optical mark reader (OMR) for scoring students' test answer sheets. The "electronic brain," as the OMR was called at the time, was a breakthrough in providing, for the first time, large-scale high-speed test scoring. However, its vacuum-tube technology was becoming obsolete, and by 1959 MRC began work on the design and development of solid-state, or transistorized, circuitry to replace the less stable vacuum tubes. The bulk of the papers document activities at the MRC from 1959 to about 1980 from the perspective of a project engineer, and later engineering manager, who was closely involved with assignments leading to the expanded use of standardized tests and test scoring, electronic balloting, and other applications of scan-related technologies. Development of the American College Testing program, a project of the MRC, is included. The papers also offer a glimpse into the corporate culture of Westinghouse Corporation, which acquired MRC in 1968 as Westinghouse Learning Corporation (WLC). WLC was, in turn, acquired by National Computer Systems in 1983. (Later, in 2000, it was acquired by NCS Pearson and became Pearson Educational Measurement in 2002. Documents in this collection pertain mainly to the MRC-WLC era.) Items of interest include a 1952 proposal for an electronic high-speed test-scoring machine, accompanied by notes by Prof. Lindquist (Box 2, Folder 1); correspondence concerning patent filings; and technical and project reports. In addition to documents, the collection includes several artifacts that represent the state of technology at the time of their design and manufacture, including an early-1960's era computer memory module with a capacity of less than 1 kilobyte. Photographs depicting early automated test-scoring apparatus of the 1950's and 1960's located in the basement of East Hall (later renamed Seashore Hall) are in Box 2, Folder 4. The collection is organized into four series: Series I and II, which reflect two accessions of documents prepared by Mr. McMillin; Series III, which includes information about the collection both in paper and digital formats; and Series IV, consisting of artifacts. Materials in Series II are generally arranged in chronological order. Many of the folder titles in Series II (e.g., "1953_11_03_SUI" in Box 2, Folder 2) reflect their matching digital file titles on DVD.
