Rasch Meta-Metres of Growth for Some Intelligence and Attainment Tests
暫譯: 某些智力與成就測試的Rasch增長元測量

David Andrich first graduated in Mathematics, then in Education, and received a Fulbright Award for study for his PhD in the Measurement, Evaluation and Statistical Analysis Program at The University of Chicago, United States. His dissertation earned the Susan Colver Rosenberger prize for the best research thesis in the Division of the Social Sciences in 1973. He returned to his appointment at The University of Western Australia, and in 1985 was appointed Professor of Education at Murdoch University in Western Australia, where he held the position of Dean for two periods. In 2007, he returned to The University of Western Australia as the Chapple Professor of Education. He is also Visiting Professor in Educational Assessment at The University of Oxford, United Kingdom. He has also been a visiting Professor at The University of Trento in Italy, and visiting Scholar at the University of Copenhagen and The University of Chicago. He has held major research grants from the Australian Research Council continuously since 1985. David has also conducted commissioned research at both national and state levels, and has been a member of expert advisory committees at national and state levels concerned with large-scale assessments. In 1990, he was elected Fellow of the Academy of Social Sciences of Australia for his contributions to measurement in the social sciences. David is especially known for his work in modern test theory, and in particular Rasch measurement theory, where his work has ranged from the philosophy of measurement, through model exposition and interpretation, to software development. He has also given invited addresses at many conferences and has published in Educational, Psychological, Sociological and Statistical journals.

Ida Marais is a Senior Research Fellow at the GSE Psychometric Laboratory, The University of Western Australia. After graduating with a BSc degree majoring in Computer Science and Psychology, she has worked as a computer analyst/programmer for a number of years before being awarded a University of Auckland Doctoral Scholarship and completing a MSc and PhD in Cognitive Psychology. Since then, Ida has been a researcher and lecturer in the fields of Psychology and Education in New Zealand and Australia. Her research activities focus on psychological and educational measurement, especially the measurement of change over time and simulation of data that violate the Rasch model. Ida's current research investigates the issue of maintaining invariant scales in state, national and international level assessments. She has written and continues to develop a data simulation program to study the implications of specific, various violations of responses according to the Rasch model, and the program is used by colleagues worldwide both for research and teaching of the Rasch model. Ida also jointly coordinates postgraduate units in Rasch measurement and supervises postgraduate students in educational measurement. She consults on a number of projects, including the audit of the Undergraduate Medicine and Health Sciences Admission test (UMAT) analysis and the analysis of the Australian national assessment Program (NAPLAN).

Sonia Sappl is a Research Assistant at the GSE Psychometric Laboratory, The University of Western Australia. After graduating with a BSc degree majoring in Psychology and Neuroscience, she has completed a Graduate Diploma in Professional Education, and is currently enrolled in a Master of Philosophy (Research) at The University of Western Australia. In her role as a research assistant, Sonia has assisted with the statistical analysis of the National Assessment Program for Science Literacy (NAP-SL) data for calibration and equating.

大衛·安德里奇（David Andrich）首先獲得數學學位，然後獲得教育學位，並獲得富布萊特獎學金在美國芝加哥大學的測量、評估與統計分析博士課程進行研究。他的論文在1973年獲得社會科學部最佳研究論文的蘇珊·科爾弗·羅森伯格獎（Susan Colver Rosenberger prize）。他回到西澳大利亞大學任職，並於1985年被任命為西澳大利亞默多克大學的教育學教授，並在該校擔任了兩屆院長。2007年，他回到西澳大利亞大學，擔任查普爾教育學教授（Chapple Professor of Education）。他同時也是英國牛津大學的教育評估訪問教授。他還曾在意大利特倫托大學擔任訪問教授，並在哥本哈根大學和芝加哥大學擔任訪問學者。自1985年以來，他持續獲得澳大利亞研究委員會的重大研究資助。大衛還在國家和州級別進行委託研究，並曾是與大規模評估相關的國家和州級專家諮詢委員會的成員。1990年，他因在社會科學測量方面的貢獻被選為澳大利亞社會科學學院的院士。大衛特別以其在現代測試理論方面的工作而聞名，尤其是拉施測量理論（Rasch measurement theory），他的研究範圍從測量哲學、模型闡述與解釋到軟體開發。他還在許多會議上發表過受邀演講，並在教育、心理學、社會學和統計學期刊上發表過文章。

艾達·馬賴斯（Ida Marais）是西澳大利亞大學GSE心理測量實驗室的高級研究員。她獲得計算機科學和心理學的理學士學位後，曾擔任計算機分析師/程式設計師多年，隨後獲得奧克蘭大學的博士獎學金，並完成了認知心理學的碩士和博士學位。此後，艾達在新西蘭和澳大利亞的心理學和教育領域擔任研究員和講師。她的研究活動專注於心理和教育測量，特別是隨時間變化的測量以及違反拉施模型的數據模擬。艾達目前的研究探討在州、國家和國際級別評估中維持不變量表的問題。她撰寫並持續開發數據模擬程式，以研究根據拉施模型的特定各種反應違規的影響，該程式被全球同事用於拉施模型的研究和教學。艾達還共同協調拉施測量的研究生單元，並指導教育測量的研究生。她參與多個項目的諮詢，包括本科醫學與健康科學入學考試（UMAT）分析的審核以及澳大利亞國家評估計劃（NAPLAN）的分析。

索尼亞·薩普爾（Sonia Sappl）是西澳大利亞大學GSE心理測量實驗室的研究助理。她獲得心理學和神經科學的理學士學位後，完成了專業教育的研究生文憑，並目前在西澳大利亞大學攻讀哲學碩士（研究）學位。作為研究助理，索尼亞協助進行國家科學素養評估計劃（NAP-SL）數據的統計分析，以進行標定和等化。
