Background: Practical work in school science has been ineffective due to students not connecting hands-on to minds-on aspects. With the designation Thinking-Back-and-Forth (TBF)we present a framework with a taxonomy of TBF activities. Purpose: Aim was to gain insight how teachers stimulate and support their students in TBF. Detailed information…

Design activities are gaining interest as rich contexts for learning science, technology, engineering, and mathematics (STEM) subjects. STEM teachers may find this challenging however, as designing requires support that they are not used to providing. In a subject like chemistry, teachers would have to balance creativity and responsibility for the…

A context-based approach to education aims to improve students' meaningful learning and uses authentic situations in which scientific concepts are applied. The use of contexts may contribute to the learning of abstract concepts such as algorithms. The selection of appropriate contexts, however, is challenging for teachers. It is therefore…

This small-scale, qualitative study uses educational design research to explore how focusing on argumentation may contribute to students' learning to engage in inquiry independently. Understanding inquiry as the construction of a scientifically cogent argument in support of a claim may encourage students to develop personal reasons for adhering to…

Developing students' critical thinking skills is often seen as an important educational goal for inquiry assignments. In this study, we investigated to what extent pre-laboratory activities of a chemical inquiry assignment influence students' independent critical thinking. We compared two forms of pre-laboratory activities that are frequently used…

Background: Although cutting-edge chemistry research can be an interesting and motivating context for students in pre-university education, few characteristics of supportive and effective learning materials based on such contexts are available. Purpose: In this study we investigated the design, implementation, and evaluation of context-based…

Students at upper secondary and college level in many countries are introduced to quantum physics (QP) in a mostly mathless course. Research shows that addressing epistemological and philosophical aspects would be beneficial for novice students' conceptual understanding. However, physics teachers seldom address these nature of science (NOS)…

Secondary science education plays a key role in students' process to become scientifically literate citizens. However, teaching students to acquire the necessary skills and knowledge to deal with complex societal issues is challenging. This paper reports about a study in which Scrum -- a methodology to manage complex projects -- was implemented in…

Chemistry plays an important role in developing scientific theories to describe, explain, and predict the physical world and to produce useful products for improving quality of life throughout history. To arouse student awareness of the value and importance of learning chemistry and becoming chemistry literate, we propose an application of systems…

Mathematics is of major importance in science subjects. Unfortunately, students struggle with applying mathematics in science subjects, especially physics. In this qualitative study we demonstrate that transfer of algebraic skills from mathematics in physics class can be improved by using pre-knowledge effectively. We designed shift-problems…

Secondary school teaching of evolution through natural selection is very important because for most people, it is the only formal introduction to the scientific understanding of this theory. However, there are major concerns over its unsatisfactory teaching. In several European countries, including the Flanders region in Belgium, natural selection…

Sustainability has become a prominent theme in society and can be considered as an integral part of scientific citizenship. This study investigates to what extent the production, use and re-use of (bio)plastics initiates students' reasoning and to identify the kind of content knowledge students put forward. The structure of students' arguments was…

The current trend in science learning leans more towards interdisciplinary (integrated) learning. Before 1989, several studies reviewed articles related to integrated science. However, research discussing articles on integrated science from 1996 until the present day is not yet available. The purpose of this study was to review 36 empirical…

Teaching a hands- and minds-on course, in which feedback is essential in order to learn, is difficult, especially in times of COVID-19 where student progression cannot be monitored directly. During the lockdown period, the workshops of an undergraduate Design Engineering course had to be transferred to the home situation, which required a redesign…

This paper describes the design process for a digital instructional sequence on introductory quantum physics for upper secondary education. Based on a collaboration between teachers and physics education researchers, this sequence incorporates relevant theoretical foundations from the field of science teaching to promote meaningful and conceptual…
