Students at all levels of education experience difficulties with the concepts of measurement uncertainties. One task that includes concepts of measurement uncertainties is a data comparison problem where students decide whether two datasets are in agreement or not--an authentic scientific practice. To aid students with these concepts and tasks,…

Educational technologies in mathematics typically focus on fostering either procedural knowledge by means of structured tasks or, less often, conceptual knowledge by means of exploratory tasks. However, both types of knowledge are needed for complete domain knowledge that persists over time and supports subsequent learning. We investigated in two…

Assessing cases of child welfare requires the ability to engage with different sources of information systematically. This study examined how case-based learning (CBL) can be used to support social work students (N = 104) acquire knowledge crucial to assessing cases of child welfare and whether benefits of CBL could be maximized by structuring the…

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…

The present study investigates the processes of how German middle school students (age 14) interpret, contrast and evaluate different (informal) statistical measures in order to summarise and compare frequency distributions. To trace the developing insights into the properties of these measures, this paper uses the 'emergent modelling'…

The German National Education Standards (NES) for biology were introduced in 2005. The content part of the NES emphasizes fostering conceptual knowledge. However, there are hardly any indications of what such an instructional implementation could look like. We introduce a theoretical framework of an instructional approach to foster students'…

Comparing places represents one of the most traditional threads of comparative inquiry. However, international and comparative (adult) education research has to date focused on comparing places more in the sense of territorial entities. In contrast, this paper moves away from understandings of national or regional territories as given,…

In an experiment, prior to processing instructional explanations N = 75 students received either (a) contrasting cases plus comparison prompts, (b) contrasting cases plus provided comparisons (i.e., model answers to the comparison prompts), or (c) no preparation intervention. We found that the learners with preparation intervention learned more…

Besides viewing knowledge about the nature of science (NOS) as important for its own value with respect to scientific literacy, an adequate understanding of NOS is expected to improve science content learning by fostering the ability to interrelate scientific concepts and, thus, coherently acquire scientific content knowledge. However, there is a…

Curriculum materials explicitly designed to foster teacher learning represent a prominent route to professional development (PD) for teachers. However, it is unclear whether PD can be delivered successfully in the form of teacher self-study of curriculum materials, or whether it has to be scaffolded additionally by an expert. This study…

Over the last 20 years, science education studies have reported that there are very different understandings among students of science regarding the key aspects of climate change. We used the cognitive linguistic framework of experientialism to shed new light on this valuable pool of studies to identify the conceptual resources of understanding…

Introduction: With regard to the internal/external frame of reference model of academic self-concept development the present study aimed at testing its theoretical assumptions within the verbal domain--namely to analyze the relations between achievement and self-concept in the native language German (L1) and the foreign language English (L2). Due…

Presents a continuation of previous research on a general development process consisting of successive levels in conceptualization. Explores how young children conceptualize the writing system. Considers both social background and preschool system of education. Concludes that teaching activities used in French nursery schools are less effective…
