The different facets of professional performance of teachers are being debated in the current educational
research discussion. Both qualitative and quantitative test constructions exist for vignette-based measurement of
competence. For economic reasons, a procedure with closed-ended items is often favored, a reference is required for
determining and comparing alternative responses. This paper sketches out the procedure for identifying adequate
reactions to responses that we call a technical education expert norm (PCK-T). This expert norm is generated from
a multi-step expert survey and, in addition, reveals possible validation steps that can be derived for developing
teaching situations. After a content validation (N1 = 8) a multi-step quantitative survey with specialised subject
experts at schools and universities, departmental heads at public colleges for education and teacher training, as well
as experienced teachers of technology was carried out (N2 = 79; N3 = 76). In order to assess teaching competencies
of pre-service teachers using a vignette-based test procedure, the generated technical education expert norm (PCKT) allows adequate responses to be differentiated from (rather) inadequate responses in the teaching situations
We consider groups defined by non-empty balanced presentations with the property that each relator is of the form, where x and y are distinct generators and is determined by some fixed cyclically reduced word that involves both a and b. To every such presentation we associate a directed graph whose vertices correspond to the generators and whose arcs correspond to the relators. Under the hypothesis that the girth of the underlying undirected graph is at least 4, we show that the resulting groups are non-trivial and cannot be finite of rank 3 or higher. Without the hypothesis on the girth it is well known that both the trivial group and finite groups of rank 3 can arise.
Females and students of non-dominant ethnicity are less likely to aspire to science careers. However, overcoming discrimination in science and chemistry is a challenging task, especially in vocational orientation. Thus, there is a need for strategies to support young women in their identity formation in science and chemistry. This article presents a scheme for supporting young women’s science identity formation in conversations about vocational orientation. The goal is to support young women in developing a positive attitude towards careers in chemistry. This attitude is part of cultural chemistry capital. The scheme was developed based on a study conducted as part of the project DiSenSu. Here, coachings for vocational orientation for young women in science and chemistry are provided, following the idea of Science in Public. In the coaching, the attitudes towards science and chemistry were determined using quantitative data. Based on these results, coaches conducted conversations with the participants. Qualitative analysis of 11 conversations revealed strategies coaches used to support young women in their vocational orientation. The study shows how the participants’ attitude towards careers in chemistry is used as a starting point for coachings. Also, it provides strategies that can be used to promote young women’s cultural chemistry capital.
In this study, the relationship between religiosity and value priorities is differentiated, based on a multidimensional model of religiosity (Structure-of-Religiosity-Test). The structure of values is conceptualized using Shalom H. Schwartz’s two orthogonal dimensions of self-transcendence vs. self-enhancement and openness to change vs. conservation. The relationship between these two dimensions and the centrality of religiosity, seven religious orientations, seven emotions toward God, and three political orientations were tested with a correlational analysis in a sample of members of Abrahamic religions, the non-denominational, and organized secularists in Switzerland (n = 1093). The results show, that different values are preferred (self-direction, universalism, benevolence, tradition, security, and power values) depending on the content of the religious orientations and emotions toward God. The results indicate the importance of the content of religious orientations and emotions for predicting value-loaded behaviors.
To successfully cope with global challenges such as climate change or loss of biodiversity, it will require a substantial change in the ways societies make use of the natural resources of our planet. Education for Sustainable Development (ESD) is expected to support the transformation of societies towards more sustainable ways of thinking, working, and living. Although there is a broad range of literature on ESD, little is known about the role of school leadership in ESD. However, leadership is crucial for the implementation of ESD in schools. This article gives a short overview of the status of ESD within Germany, Macau, and the United States and a literature review on leadership for ESD in schools. It reports on a study that seeks to investigate what principals do in Germany, Macau, and the United States; specifically, what management strategies they use and which competences they need to successfully establish ESD in their schools.
A crucial aspect of learning about (linear) functions is being able to change between graph and equation. Common German and Slovak textbooks propose different procedures for these representational changes. Within a sample of 49 German and 56 Slovak teachers, we analyzed if these different procedures can also be observed in the teachers’ corresponding knowledge of content and students, i. e. if the teachers expected different student strategies and errors. The results confirm this assumption and emphasize the importance to consider this teacher's knowledge in a country-specific way and being careful when comparing such knowledge of teachers from different countries.
For some people with strong motor impairments, controlling a computer with theeyes is the only possibility for human-computer interaction. In addition, gaze controlis becoming a new option as an input device for the general population as wellbecause of the increasing availability of eye-tracking technology. Yet, little is knownabout additional cognitive demands involved in gaze control and how to handlepotentially high demands when using the eyes not only for perception but also foraction. The present study shows that cognitive offloading improves performancewhen using gaze control. Memory for to-be-studied items benefitted significantlyfrom saving another set of items just studied before for later restudy. Employing cog-nitive offloading in a targeted manner may be a useful means to assist in mastering eye-gaze control.
Two experiments examined effects of including an information about a disability in a person description on memory about that person’s traits. In Experiment 1, this information impaired correct recognition of traits of a person that had been described in correspondence to gender stereotypes. In Experiment 2, it induced false memories in accordance with stereotypes about people with disabilities. Participants’ false alarms for traits belonging to the dimension of warmth increased, whereas false alarms for traits belonging to the dimension of competence decreased. Thus, activating stereotypes through a disability prime influenced what could be recognized correctly or falsely was assumed to be recognized about a person.
The saving of previously encoded information boosts both memory for subsequent information (saving-enhanced memory; SEM) as well as cognitive performance in general (saving-enhanced performance; SEP). These findings have been replicated in a setting that involves the assistance by an intelligent software that automatically structures and saves work content in an interactive sidebar. It is assumed that beneficial effects on cognitive performance due to (automatic) saving are caused by a reduction in current workload by means of cognitive offloading. We tested this assumption by measuring neural activity in the dorsolateral prefrontal cortex (DLPFC) via functional near infrared spectroscopy (fNIRS)—once after saving and once after deleting of previously collected information that had to be recalled later-on. On a behavioral level, there was a brief benefit of saving. However, cognitive offloading became most apparent on a neural level: after saving, participants showed significantly lower activation in the right DLPFC. Also, the more participants benefited from cognitive offloading, the more they were able to re-access previously collected, saved information. Thus, fNIRS results indicated reduced mental load after saving, confirming the assumption that saving triggers cognitive offloading.
