Diagnosis is a prerequisite for successful professional problem-solving: A physician identifies an appropriate treatment based on a diagnosis of the patient’s disease, and a teacher selects an appropriate learning task based on an assessment of the student’s prior knowledge. Education in academic professions such as medicine or teaching is often focuses on the acquisition of conceptual knowledge from lectures and books; opportunities for students to engage in practical diagnostic situations are typically rare. However, applying such conceptual knowledge in diagnostic activities is regarded as necessary for developing diagnostic competences. In this article, we focus on simulations in which students can actively engage in practicing diagnostic activities concerning cases from professional practice. We review and link research perspectives on diagnostic competences, their components and their development. This is partly done by exploring the commonalities and differences in research on diagnostic competences in medicine and teaching. Then, we present approaches to simulation, followed by different types of instructional support in such simulations. In particular, we focus on different forms of scaffolding during problem-solving, and on the possibly complementary roles of expository forms of instruction in these kinds of environments. Building on the perspectives reviewed, we propose a framework for fostering diagnostic competences in simulations in higher education and outline an interdisciplinary research approach concerning the instructional design of such simulations.

This study examined the effects of teachers’ biology-specific dimensions of professional knowledge – pedagogical content knowledge (PCK) and content knowledge (CK) – and cognitively activating biology instruction, as a feature of instructional quality, on students’ learning. The sample comprised 39 German secondary school teachers whose lessons on the topic neurobiology were videotaped twice. Teachers’ instruction was coded with regard to cognitive activation using a rating manual. Multilevel path analysis results showed a positive significant effect of cognitive activation on students’ learning and an indirect effect of teachers’ PCK on students’ learning mediated through cognitive activation. These findings highlight the importance of PCK in preservice biology teachers’ education. Items of the rating manual may be used to provide exemplars of concrete teaching situations during university seminars for preservice teacher education or professional development initiatives for in-service teachers.

Vertebrate species knowledge, a key factor for conserving biodiversity, is a compulsory part of school curricula. This study evaluated the vertebrate species knowledge of sixth-grade German grammar school pupils (aged 11–13) to investigate the influence of socio-demographic factors (gender, size of hometown, mother tongue), personal expectations (favourite school subject, performance in biology, expected test results) and possibilities to do nature observations (favourite playing area, number of excursions to nature) on identification skills. In addition, the study examined whether schoolchildren's taxonomic knowledge changed over the years. In a species identification test, participants (N = 984) scored an average of 14.18 ± 3.82 out of 25 points. The results showed that their species knowledge was significantly influenced by their personal expectations on test performance, the school, favourite playing area, mother tongue and gender. Hometown size, the number of excursions to nature, favourite school subject and performance in biology did not significantly affect children's species knowledge. Mammals had the highest identification rates, whereas birds and reptiles were rather unknown. These results were compared with a similar dataset in 2006 indicating a 15% loss in pupils’ species knowledge within the last decade. A change in the curriculum as a reason for this decline in taxonomic knowledge is discussed.
