Technology-Based Assessment

In the last decades, the digitalization of educational content, the integration of computers in different educational settings and the opportunity to connect knowledge and people via the Internet has led to fundamental changes in the way we gather, process, and evaluate information. Also, more and more tablet PCs or notebooks are used in schools and—in comparison to traditional sources of information such as text books—the Internet seems to be more appealing, versatile, and accessible. Technology-based assessment has been concerned with questions of comparability of test scores across test media, transferring already existing measurement instruments to digital devices. Nowadays, researchers are more interested in enriching the assessment by using interactive tasks and video material or make the testing more efficient using digital behavior traces.

Science self-concept – More than the sum of its parts?

The article “Science Self-Concept – More Than the Sum of its Parts?” has now been published in “The Journal of Experimental Education” (btw in existence since 1932). The first 50 copies are free, in case you are interested.

In comparison to the preprint version, some substantial changes have been made to the final version of the manuscript, especially in the research questions and in the presentation of the results. Due to word restriction, we also removed a section from the discussion, in which we summarized differences and commonalities of the bifactor vs. higher-order models. We also speculated about why the type of modeling may also depend on the study’s subject, that is, on conceptual differences in intelligence vs. self-concept research. The argumentation may be a bit wonky, but at least I find the idea so persuasive that I want to reproduce it in the following. If you have any comments, please feel free to drop me a line.

The Rosenberg Self-Esteem Scale - A drosophila melanogaster of psychological assessment

I had the great chance to co-author two recent publications of Timo Gnambs, both dealing with the Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1965). As a reminder, the RSES is a popular ten item self-report instrument measuring a respondent’s global self-worth and self-respect. But basically both papers are not about the RSES per se, rather they are applications of two recently introduced powerful and flexible extensions of the Structural Equation Modeling (SEM) Framework: Meta-Analytic Structural Equation Modeling (MASEM) and Local Weighted Structural Equation Modeling (LSEM), which will be described in more detail later on.
