The Rasch model provides a strict correspondence provided all students attempt the same test items, or their performances are marked using the same marking rubrics. In terms of the broad body of purely mathematical theory drawn on, there is substantial overlap between educational measurement and psychometrics.
There is also an increasing attention to scientific modelling [4] in fields such as science education, [5] philosophy of science, systems theory, and knowledge visualization. There is a growing collection of methods, techniques and meta-theory about all kinds of specialized scientific modelling.
CEMO's mission is, firstly, to move the field of educational measurement forward. This includes an orientation towards action such as the development of instruments that balance educational quality, equity, and effectiveness, but also towards reaction such as addressing concerns about unintended consequences and side-effects of assessments by examining these in-depth.
Measurement is a cornerstone of trade, science, technology and quantitative research in many disciplines. Historically, many measurement systems existed for the varied fields of human existence to facilitate comparisons in these fields.
Science is the process of gathering, comparing, and evaluating proposed models against observables. A model can be a simulation, mathematical or chemical formula, or set of proposed steps. Science is like mathematics in that researchers in both disciplines try to distinguish what is known from what is unknown at each stage of
In contrast, probabilistic measurement models known as the Rasch model and Item response theory models are generally employed in the social sciences. Psychometrics is the field of study concerned with the theory and technique for measuring social and psychological attributes and phenomena.
Moreover, scientific literacy provides an important basis for making informed social decisions. Science is a human process carried out in a social context, which makes it relevant as a part of our science education. In order for people to make evidence-informed decision, everyone should seek to improve their scientific literacy. [35]
Over the course of 10 years, this work led to the establishment of measurement systems in reading, writing, and spelling that were: (a) easy to construct, (b) brief in administration and scoring, (c) had technical adequacy (reliability and various types of validity evidence for use in making educational decisions), and (d) provided alternate ...
