The "Hagen Cumulative Science Project" is a large-scale replication project based on students' thesis work. In the project, we aim to (a) teach students to conduct the entire research process for conducting a replication according to open science standards and (b) contribute to cumulative science by increasing the number of direct…

The course design "Training OC" for training the application of basic concepts consists of four topics: formula language, structure-property relations, reaction mechanisms, and complex tasks that the students should solve with the conceptual knowledge they acquired in the first three topics. A main goal of the course was to enable the…

Learning to interpret organic structures not as an arrangement of lines and letters but, rather, as a representation of chemical entities is a challenge in organic chemistry. To successfully deal with the variety of molecules or mechanistic representations, a learner needs to understand how a representation depicts domain-specific information.…

A concept for undergraduate mechanics courses at universities is introduced where traditional pencil-paper based exercises are partially replaced by experimental exercises, in which smartphones are used as measurement devices. A detailed guidance for practical realization and implementation of these tasks formats into the course is presented.…

The Participatory Action Research (PAR) model developed by Eilks and Ralle is very well known in science education. Over the years, many teaching and learning materials have been developed and implemented in German secondary schools using this method. The success of the model encouraged us to adapt it to the university level in order to develop…

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…

Visualizations and visual models are of substantial importance for science learning (Harrison and Treagust, 2000), and it seems impossible to study chemistry without visualizations. More specifically, the combination of visualizations with text is especially beneficial for learning when dual coding is fostered (Mayer, 2014). However, at the same…

We designed, implemented, and evaluated a game-based learning approach to increase student motivation and achievement for an undergraduate physical chemistry course. By focusing only on the most important game aspects, the implementation was realized with a production ratio of 1:8 (study load in hours divided by production effort in hours).…

The role of faculty in higher education as knowledge disseminators within the knowledge and digital society can be completely redefined. This paper presents results from a video-based flipped classroom approach combined with a project-oriented learning arrangement. I show that videos combined with a project-based learning setting can be a powerful…

Early photography processes were predestined to combine chemistry and art. William Henry Fox Talbot is one of the early photography pioneers. In 2-3 day workshops, design students without a major background in chemistry are able to define a reproducible protocol for Talbot's gallic acid containing calotype process. With the experimental concept…

A simple, reliable, and cost-effective experiment is presented in which students synthesized citrate-capped gold nanoparticles (GNPs), functionalized them with poly(ethylene glycol) (PEG), and transferred the PEG-GNPs from water to the organic phase dichloromethane. The experiment introduces students to nanotechnology with foci on important…

Prismatic refraction is a classic topic in science education. To investigate how undergraduate students think about prismatic dispersion, and to see how they change their thinking when observing dispersed images, five teaching experiments were done and analysed according to the Model of Educational Reconstruction. For projection through a prism,…

This study investigated the effectiveness of three different instructional materials for learning how to identify fish at the species level in a blended classroom and out-of-classroom scenario. A sample of 195 first-year students of biology or geoecology at the University of Tuebingen participated in a course on identification of European…

Currently not many people would doubt that computers play an essential role in both public and private life in many countries. However, somewhat surprisingly, evidence of computer use is difficult to find in German state schools although other countries have managed to implement computer-based teaching and learning in their schools. This paper…

Context-based chemistry education aims to improve student interest and motivation in chemistry by connecting canonical chemistry concepts with real-world contexts. Implementation of context-based chemistry programmes began 20 years ago in an attempt to make the learning of chemistry meaningful for students. This paper reviews such programmes…
