Numerous effective digital learning environments have evolved over the last few years built around video examples that follow an introduction phase and are often supplemented by prompts. The learning mechanisms behind these components remain subject to open questions, though. We thus conducted an online experiment with university students (N =…

In two experiments with German secondary school students (N[subscript 1] = 43; N[subscript 2] = 41), we aimed to analyze and optimize an effective learning environment. We sought further active ingredients and crucial factors for deep processing during an example-based training intervention, which consisted mainly of video examples and…

Promoting teachers to lead classroom discourse effectively is a relevant topic for teacher professional development worldwide. This study compares the impacts of two teacher professional development programmes that aim to support teachers in their classroom discourse practices. In one programme, an adaptive and practitioner-led approach was…

The teacher echo refers to teachers' almost verbatim repetition of student responses and can be used to provide implicit feedback about students' achievement or understanding. Echoing student answers is a controversial strategy of classroom discourse, as some critics see it as a bad habit and consequently deny its use in the classroom. The aim of…

The paper addresses concept formation processes of students in the field of geometry. More precisely, the paper deals with the questions of what knowledge do students activate about triangles in different contexts with different (digital) tools and furthermore what content-related meaning do they give to the concept of triangles? Methodologically,…

The ability to reflect on teaching is crucially important for the professionalization of trainee teachers. The fostering of reflection processes -- by means of the systematic analysis of one's own and others' teaching from subject-specific, methodological, and educational science perspectives -- plays a central role in a continuing and consecutive…

Teachers are confronted with multiple stimuli during instruction. To teach responsively, they must be able to identify and address classroom incidents that are critical for student learning. In the literature, the term "noticing" is used to refer to teachers' perception and interpretation of such incidents, as well as the associated…

Emotions have an essential impact on students' learning outcome. Empirical findings show negative correlations between negative emotions and learning outcome. Negative emotions during learning are quite common and become more frequent over the course of an academic career. Thus, regulating these emotions is important. Existing studies indicate…

In 2013, the so-called Viducation project was launched at the Institute of Romance Studies at the University of Kiel4 (CAU) as a reaction to the new Bachelor of Arts and Masters of Arts degree programmes in order to improve students' learning skills and core competences by creating subject-related videos. Filmmaking by students is already widely…

Studies have shown the potential of explainer videos. An alternative is a written explanation, as found in science textbooks. Prior research suggests that instructional explanations sometimes lead to the belief that a topic has been fully understood, even though that is, not the case. This 'illusion of understanding' may be affected by the medium…

Despite an increasing number of studies demonstrating that young children selectively learn from others, and a few studies of children's selective teaching, the evidence almost exclusively comes from Western cultures, and cross-cultural comparison in this line of work is very rare. In the present research, we investigated Japanese and German…

A rising number of (online) learning scenarios feature video-based worked examples. We analyzed the effects of the presentation mode of worked examples on their effectiveness and efficiency in two experiments with university students (N[subscript 1] = 57; N[subscript 2] = 43). The students acquired argumentation knowledge by self-explaining…

To what degree can multilingual students profit from bilingual teaching approaches, even when they lack experience in the academic or technical register in their home languages? This study explores this research question in a mixed methods design for a German/Turkish bilingual intervention aimed at fostering conceptual understanding of fractions…

Background: Teachers' important diagnostic abilities include noticing and interpreting students' behaviors and learning processes. By focusing on noticing, I refer to the theoretical framework of professional vision. Professional vision includes the ability to notice what is occurring in complex classroom situations (selective attention) and the…

The investigation of learning processes by assessing students' experience along with objective characteristics within a classroom context has a long tradition in empirical learning process research (e.g. Sembill, 1984 et passim; Wild & Krapp, 1996). However, most of the existing studies confine themselves to psychological variables that seem…
