Well-chosen covariates boost the design sensitivity of individually and cluster-randomized trials. We provide guidance on covariate selection generating an extensive compilation of single- and multilevel design parameters on student achievement. Embedded in psychometric heuristics, we analyzed (a) covariate "types" of varying…

This systematic review investigates the relevance of general pedagogical knowledge for successful teaching. It synthesises the empirical evidence of 10 769 teaching professionals and 853 452 students from primary to tertiary education in 21 countries. The meta-analysis of 20 quantitative studies revealed significant effects for teaching quality…

Feedback plays an important role in supporting students' learning process. Nonetheless, providing feedback is still rather unusual in higher education. Moreover, research on the design of ideal feedback as well as its effects is rare. In order to contribute to the development of this field, a web-based feedback system was implemented in a lecture…

Background/Context: Two key uses of international assessments of achievement have been (a) comparing country performances for identifying the countries with the best education systems and (2) generating insights about effective policy and practice strategies that are associated with higher learning outcomes. Do country rankings really reflect the…

Purpose: The overall purpose of the European Union-funded Leadership Improvement for Student Achievement (LISA) project was to explore how leadership styles, as conceptualized in the developed dynamic holistic leadership framework, directly or indirectly affect student achievement at the lower secondary level of education in seven European…

States that international and national evaluations of educational achievement provide data on distributions, structures, and correlates students' competence and achievement. Argues that these cross-sectional designs do not allow any conclusions on the antecedents and consequences of students' achievement, or on educational interventions. Discusses…

Provides brief history of the German Gymnasium as a traditional European secondary school system with a preparatory function for higher education. Reviews the main goals of the gymnasium. Asks what role the gymnasium plays as a learning environment for gifted students. Discusses the politico-educational consequences and demands on the gymnasium.…

This paper discusses the contribution of international studies on educational effectiveness in the light of 4 papers presented at the new ICSEI Methodology of Research and Effectiveness (MORE) Network in Barcelona in January 2005 and published in this issue of the journal. A brief historical overview is used to provide a context for these papers…

Individual differences in academic success were investigated in a geographically defined whole-population sample of very preterm children with a gestational age of less than 32 weeks or a birth weight of less than 1500 gm. The sample consisted of 264 very preterm children (75.6% of German-speaking survivors) and 264 controls matched for gender,…

Based on Inglehart's (1997) idea that the importance of modern values is challenged by a growing importance of postmodern values in postindustrialised societies, we analyse the consequences of students' attempts to integrate (modern) achievement values and (postmodern) well-being values. Since opportunities for value integration are limited,…

Discusses the International Survey on Reading Abilities in Primary School (IGLU) and its data on achievement in reading, mathematics, and natural science. Compares this data to that collected by the Program for International Student Assessment (PISA). Identifies achievement relevant correlations such as gender, migration background, socioeconomic…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
