In a design-research project on problem-solving, theory-based and practice-oriented materials were developed with the goal of fostering systematical development of students' problem-solving competence in a targeted manner by learning heuristics. Special attention was given to working backward strategy, which has been shown difficult for students…

The ability to read adequately is one of the most important skills for students to achieve during their school career. Unfortunately, a large number of children do not have adequate reading skills and thus may face problems in many respects throughout their lives. Children with learning disabilities (LD) and behavioral problems are particularly…

This study replicates and extends prior research on multisensory mathematics instruction (Grünke, Urton, & Karnes, 2018) by integrating a touch points strategy, performance feedback, reward system, and a reinforcing card game into an instructional package. A multiple baseline design across participants was used to evaluate the effects of the…

Students with learning and behavioral problems often face enormous barriers to successful school performance. When the language of instruction is not the students' first language and they are already in secondary school, this is compounded by additional challenges, especially with regard to vocabulary and reading -- subjects that are fundamental…

Combinations of text and different types of pictures are commonplace in biology as in science in general. The single representations (i.e., text, picture) constituting a text-picture combination may contain redundant or complementary information. The ability to identify and integrate information in different kinds of text-picture combinations is…

The COVID-19 pandemic has significantly affected the education system worldwide, which was forced to respond with a sudden shift to distance learning. While successful distance teaching requires careful thinking, planning, and the development of technological and human resources, there was no time for preparation in the current situation. Various…

In the project MultiMa (Multiple solutions for mathematics teaching oriented toward students' self-regulation), we investigated the effects of prompting students to use multiple solution methods while solving real-world problems on their learning. In this quasi-experimental study, we compared three treatment conditions. In one condition, students…

One of the most important tasks of higher educational institutions is the training of specialists to be able to adapt to changes in their professional life. At the end of the twentieth and the beginning of the 21st centuries, some methods for developing foreign language competence, needed for their future professional activity, were created by…

Problem-based learning can have a great impact on the acquisition of practical knowledge, which is a central learning aim in the field of teacher education. Therefore, we implemented a problem-based learning approach in four seminars on educational assessment. In this paper, we outline our didactic design and discuss the results of the first…

Service Learning is a modern teaching-learning concept, which combines curricular content with supporting charitable organizations. The effects of courses using this concept on the students' competences development has already been described in empirical studies. Within these studies the aspects regarding the instructional design were less…

This article investigates the participating students' evaluation of a teacher training seminar about heterogeneity in the classroom at Bielefeld University, Germany. The evaluation made use of a short questionnaire and an end-of-term test of the students' knowledge on the subject matter. The questionnaire is tested for objectivity, reliability,…

This paper describes the second in a series of studies exploring the acceptance of the subatomic structure of matter by 12-year-olds. The studies focus on a novel learning unit introducing an atomic model from electrons down to quarks, which is aimed to be used at an early stage in the physics curriculum. Three features are fundamental to the…

In 2000, the Programme for International Student Assessment (PISA) study was conducted by the Organisation for Economic Co-operation and Development (OECD). It is a worldwide study of 15-year-old students' performance in mathematics, science and reading skills. The study showed relatively poor results for German students' scientific literacy…

Problem based learning (PBL) is often introduced in curricula in form of short segments. In the literature the value of these PBL-islands is doubted. In order to gain more insight in this curricular approach, we compared student generated learning issues, from a 7-week PBL-island introduced in a traditional curriculum (PBL-I), with the gold…

In this paper the augmentation of worked examples with animations for teaching problem-solving skills in mathematics is advocated as an effective instructional method. First, in a cognitive task analysis different knowledge prerequisites are identified for solving mathematical word problems. Second, it is argued that so called hybrid animations…
