Læreres kunnskap har betydning for elevenes læring, og som et ledd i prosessen for styrking av kvaliteten i norsk skole har politikere i senere tid ytret ønske om å kartlegge læreres kunnskap. Kartlegging av læreres kunnskap er imidlertid ikke enkelt, og i denne artikkelen undersøker vi hvordan de samme lærernes undervisningskunnskap i matematikk kan se ut til å være forskjellig når den måles ved hjelp av oppgaver med ulikt format. Deltakerne i studien var 30 praktiserende lærere, og instrumentet besto av 28 flervalgsoppgaver med tilhørende åpne oppgaver. Sammenhengen mellom lærernes kunnskap slik den måles ved hjelp av flervalgsoppgavene og de åpne oppgavene er ikke alltid klar. Det er derfor nødvendig å tilnærme seg måling av læreres undervisnings-kunnskap i matematikk med stor varsomhet. Nærmere undersøkelser er nødvendig for å finne ut hva slags type kunnskap som kan måles med ulike typer oppgaver og hva slags måleinstrumenter som kan brukes til hvilke formål.Nøkkelord: Undervisningskunnskap i matematikk, kartlegging, måleinstrument-er, flervalgsoppgaver AbstractTeachers’ knowledge influence students’ learning, and as part of their attempts to increase the quality of Norwegian schools, politicians have announced their intentions to measure the knowledge of teachers. Measuring teacher knowledge is not straightforward, however, and this article investigates how a group of mathematics teachers’ knowledge might appear different when measured by items of different formats. The participants in this study were 30 in-service teachers, and the instrument consisted of 28 multiple-choice items with associated open-response items. The connection between the teachers’ know-ledge as measured by multiple-choice items and open-response items is not always straightforward. As an implication, it is necessary to approach measure-ment of teachers’ mathematical knowledge for teaching with great care. Further studies are necessary in order to investigate what types of knowledge can be measured by different types of items and how different kinds of measuring instruments can be used for particular purposes.Key words: Mathematical knowledge for teaching, measurement, instruments, multiple-choice items

Abstract In this paper, we share two conceptual replications of Hill et al.’s (2012c) study linking Mathematical Knowledge for Teaching (MKT), Mathematical Quality of Instruction (MQI), and student assessment scores. In study 1, we share data from 4th and 5th grade teachers in an urban school district. In study 2, we share data from middle school teachers in a school district with a relatively high proportion of emergent bilingual students. By varying contexts, we found that Hill et al.’s (2012c) suggested use of the MKT cutoff points was not warranted in our differing settings. Further, we found some significant relationships between MKT, MQI, and student assessments; however, we were not able to reproduce these consistently with our data. We suggest that the relationship between teaching practice and MKT may be quite sensitive to contextual factors including grade level, demographics, school effects, and assessments. We recommend that policymakers and researchers take caution when using such instruments to evaluate program initiatives and identify teachers for remediation or leadership positions.

Practical constraints in rater-mediated assessments limit the availability of complete data. Instead, most scoring procedures include one or two ratings for each performance, with overlapping performances across raters or linking sets of multiple-choice items to facilitate model estimation. These incomplete scoring designs present challenges for detecting rater biases, or differential rater functioning (DRF). The purpose of this study is to illustrate and explore the sensitivity of DRF indices in realistic sparse rating designs that have been documented in the literature that include different types and levels of connectivity among raters and students. The results indicated that it is possible to detect DRF in sparse rating designs, but the sensitivity of DRF indices varies across designs. We consider the implications of our findings for practice related to monitoring raters in performance assessments.

In their description of the mathematical work of teaching, Ball,  Bass & Hill (2004) describe the mathematical problem solving that teachers do as they go about their work. In this paper we add to this description through our study of teaching of probability in a grade 8 multilingual classroom in South Africa. We use instances of teaching to highlight the mathematical problem solving that teachers might face as they work with learners’ ideas, both expected and unexpected. We discuss  the restructuring of tasks as an inevitable feature of teachers’ work, and argue that in addition to scaling up or scaling down of the task as Ball et al. (2004) describe, restructuring can also entail shifting the mathematical outcomes from those intended. We also point out how well known issues in mathematics education, for example working with learners’ everyday knowledge, and the languages they bring to class, are highlighted by the context of probability, enabling additional insights into the mathematical work of teaching.
