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…

Science explanation videos, especially online ones, have become popular. They cover nearly all topics from school science curricula. Teachers use them in a flipped classroom. Students watch them also in their leisure time. However, there is a lack of research on guidelines that effective science explanation videos should follow. The research on…

Background: A topical research question is how pre-service teachers develop professional competencies with regard to game-centered approaches such as 'Teaching Games for Understanding' (TGfU). In this context, research on teacher education assumes reflection on teaching examples -- including real-life classroom practices -- to have positive…

Research in science education agrees that one of the key challenges of learners in the discipline is certainly connecting domain-specific representations to the underlying concepts. One way of supporting students to make applicable connections is using purposefully designed highlighting techniques in multimedia instructions. In order to examine…

The acquisition of warranted domain-specific knowledge is essential for practical work in medicine. The medical field, however, suffers from 'information overload', and students and physicians rely on access to verified, up-to-date information. Based on prior research, we investigated (1) which media medical students use for learning, (2) how…

When it comes to presenting research results, the usual approach is to use PowerPoint or similar slide applications, or to opt for alternative presentation tools. A central question is how well the knowledge is transferred and to what extent the target audience is addressed emotionally. Based on a 2*2 factorial design, the effects of presentation…

This study investigated the effects of teachers' use of "focus questions" on students' knowledge structures and classroom teaching-learning process by re-analyzing selected data from a quasi-experimental pre-post video study (Wadouh, 2007). Focus questions are content-related anchoring questions highlighting the key content taught in…

There is a significant rise in the use of videos. More and more people use videos not only as a source of information but also as learning tool. This article explores the future potential of explainer videos, a format that conveys complex facts to a target group within a very short time. The findings are based on an empirical study representative…

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…

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…

This paper addresses an important task teachers face in class: the identification and support of creative and high-achieving students. In particular, we examine whether primary teachers (1) have acquired professional knowledge during teacher education that is necessary to foster creativity and to teach high-achieving students, and whether they (2)…

This study investigates the design and effectiveness of a video tutorial for software training. In accordance with demonstration-based training, the tutorial consisted of a series of task demonstrations, with instructional features added to enhance learning. An experiment is reported in which a demonstration-only control condition was compared…

Background: Education Standards highlight the importance of conceptual knowledge. Instructional tasks play a key role in biology instruction and offer learning opportunities for students. Tasks contain of a content and a demands part. Therefore, complexity and cognitive level are adequate variables to describe tasks and are assumed effective for…

Nowadays, there is a consensus that good teaching and learning needs instructional variation and personalised forms of learning. In teacher education, these concepts have been implemented for years, and prospective teachers are taught accordingly; it is thus assumed that the teaching of novice teachers is in accordance with these new teaching…
