Excerpt from Composition:
Differentiate terms ‘criterion – referenced assessment’ ‘norm-referenced assessment’.
Robert Glaser’s 1963 paper “Instructional Technology and the Measurement of Learning Outcomes” marked a watershed in psychometrics, the measurement of educational performance. Glaser’s innovation came through classifying two particular means of assessing test final results, and his meanings continue to drive controversial change in the supply of education across the Usa to this day. The No Child Left Behind Take action of 2001 represents the maturation of your very cement and countrywide movement toward what Glaser termed “criterion-referenced measures” (Glaser 1963, l. 7), the measurement of individual scholar test outcomes against total scores intended to demonstrate mastery of schoolwork, as opposed to “norm-referenced measures” (Glaser 1963, g. 8), which usually rank students’ mastery of coursework relative to each other. The two types of measurement bring different functions at the same time, typically with the same instrument (Popham and Husek 1969, p. 19), whilst one national modern tendency seems to be a revaluation of the one above the other like they were binary opposites, rather than complimentary strategies of assessment.
The formal analyze of test performance dimension separates psychometric techniques into many categories. Glaser’s definition of criterion-referenced against norm-referenced measurement rested on a preceding distinction between aptitude and achievement screening, where abilities refers to a student’s potential to learn later on, and success testing attempts to evaluate proficiency, or students’ competence of course content material, although this kind of distinction may also be blurred (Glaser 1963, s. 6). Criterion- as opposed to norm-referenced measurement generally attempts to quantify achievements, either following presentation of target materials or equally before and after presentation, with the first test providing a benchmark against which post-teaching comprehension can then be compared (so-called ipsative measurement, where the scholar competes with herself (Neil, Wadley and Phinn 1999, p. 304)). Aptitude checks could be criterion-referenced if competence could be forecasted from certain knowledge currently obtained, apart from there would be no chance to test knowledge of material to which the student has not yet been treated. Inferential statistics will be widely used in both regimes to mean future performance, overt or unstated, although norm-referenced analysis has typically been employed for more formal aptitude or performance way of measuring, especially for apparent “High Stakes, ” or perhaps competitive testing objectives (Popham and Husek 1969, s. 21)
Although ipsative way of measuring tests a student’s knowledge against their particular prior understanding – genuinely, the prior lack thereof – after the treatment has become applied, discourse on norm- or criterion-referenced psychometrics implies students’ performance is definitely measured against each other or perhaps against a target standard, respectively. The lies in how a results are in contrast, because the two formats typically appear related in presentation and both equally depend on the validity of evidence justifying the appropriateness of individual test inquiries (Fernandez-Ballestros 1993, p. 283). The difference in how the outcomes are presented become significant because both form of assessment gives rise to generally different implications for both the buy (learning) plus the transmission (pedagogy) of subject matter content.
Strength Differences in Program, Interpretation
Colburn (2009) points out that while norm-referenced assessment is often used to evaluate individual competency and also ranking students, attempting to derive both equally types of results from precisely the same instrument can be inappropriate as the two types of measurement are structurally unique. This leaving has developed since Popham’s early discussion that the same test can yield info for both equally styles of reference (1969, s. 36). Either way, there are restrictions that underlie both however they are used. Since norm-referenced assessment even comes close students’ performance against the other person to obtain hierarchical list (best; second-best; third-best), then if most students answer a particular problem correctly, that data stage is often turned down as worthless because it reveals no big difference between evaluation subjects. Consequently this implies norm-referenced assessment takes a large enough number of questions so that all pupils do not get all of the answers right, or hierarchical ranking would be impossible and a norm-referenced assessment can be useless. Test out subjects’ rank can be sliced into percentiles, and a specific rank specified as the line between move and fail, but inside cohorts, norm-referenced assessment is usually powerless to tell apart between the same scores. Grading on the curve requires that, a competition, not a increase where all students are exactly the same.
Teaching below criterion-referenced assessment on the other hand could include a end result where all students obtained perfectly, since the designation between pass and fail would depend
