TY - JOUR A1 - Lenkeit, Jenny A1 - Schwippert, Knut A1 - Knigge, Michel T1 - Configurations of multiple disparities in reading performance BT - longitudinal observations across France, Germany, Sweden and the United Kingdom JF - Assessment in education : principles, policy & practice N2 - Research provides evidence that gender, immigrant background and socio-economic characteristics present multiple disadvantaging characteristics that change their relative importance and configurations over time. When evaluating inequalities researchers tend to focus on one particular aspect and often use composite measures when evaluating socio-economic characteristics. Neither can fully represent the complexity of students’ various disadvantaging characteristics, which have autonomous associations with attainment and with each other. This paper investigates how the relative importance and configurations of different disadvantaging factors have changed over time to form educational inequalities and how these changes differ across countries. Data from five PISA cycles (2000–2012) for France, Germany, Sweden and the United Kingdom are used and configurations of gender, immigration background, parents’ occupational and educational levels, and the number of books at home evaluated. Results enable us to relate changes (or lack thereof) in configurations of disadvantaging factors to recent reforms targeted at reducing educational inequality after the first PISA results.

However, to efficiently construct these glyco-assemblies is still a challenge. Herein, we report an efficient technology for the synthesis of glyco-inside nano-assemblies by utilizing RAFT polymerization of a galactose-decorated methacrylate for polymerization-induced self-assembly (PISA). Using this approach, a series of highly ordered glyco-inside nano-assemblies containing intermediate morphologies were fabricated by adjusting the length of the hydrophobic glycoblock and the polymerization solids content. A specific morphology of complex vesicles was captured during the PISA process and the formation mechanism is explained by the morphology of its precursor and intermediate. Thus, this method establishes a powerful route to fabricate glyco-assemblies with tunable morphologies and variable sizes, which is significant to enable the large-scale fabrication and wide application of glyco-assemblies.

Diese Studie untersucht mit internationalen PISA-Daten (Zyklen 2000–2012; 81 Länder, über 55.300 Schulen, über 1,3 Millionen 15-Jährige), inwiefern dies für Indikatoren der Qualitätsdimensionen des Unterrichts (Klassenführung, Kognitive Aktivierung, Konstruktive Unterstützung) zutrifft. Dafür bestimmten wir das Übereinstimmungsmaß rWG(J) sowie die Intraklassenkorrelationen ICC(1) und ICC(2). Es zeigte sich, dass (1) die Mehrzahl der Unterrichtsmerkmale eine moderate oder starke Übereinstimmung in Schulen aufwies, (2) sich Unterrichtsmerkmale aus Sicht der Schülerschaft systematisch zwischen Schulen unterschieden, jedoch (3) die Reliabilität der aggregierten Schülerurteile in vielen Ländern nicht ausreichte. Die Ergebnisse diskutieren wir vor dem Hintergrund von Konventionen zur Beurteilung der Übereinstimmung, Variabilität und Reliabilität auf Schulebene. N2 - Using student ratings to assess instructional quality of schools should fulfill three requirements: (1)an appropriate level of inter-rater agreement within schools, (2)systematic variance of student ratings between schools, (3)an adequate reliability level of aggregated student ratings. Using international PISA-data (2000-2012; 81countries, over 55,300 schools, over 1.3million 15-year olds) this study investigated how these requirements were met regarding indicators of instructional quality (classroom management, cognitive activation, individual learning support). We computed the interrater agreement index r(WG(J)), as well as the intraclass correlations ICC(1) and ICC(2). Our results showed that (1)student ratings demonstrated amoderate or strong level of agreement for most indicators of instructional quality and (2)instructional quality assessed by students varied systematically between schools. Yet, (3)reliability of aggregated student ratings was not sufficient in many countries. We discuss these results regarding conventions to evaluate agreement, variability, and reliability of student ratings at the school level.
