A goal of K-12 science education is for learners to develop scientificliteracy. However, realizing this goal is being complicated by the availability ofabundant resources that vary strongly regarding their adherence to the Nature ofScience principles, particularly regarding socio-scientific issues, such as, forinstance, vaccination. It requires dedicated reasoning skills, often referred to ascritical thinking, to assess and value the arguments regarding such issues.To stimulate critical thinking, we investigate the use of interactive conceptcartoons. Instead of a single cartoon our instrument provides a sequence ofconcept cartoons. The cartoons are alternated with a diagram and concepts thatlearners have to place in the diagram, leading to a systems’ view on the subjectmatter.The instrument has been presented to teachers for expert review and evaluatedin three classrooms (6th grade) of one school (70 learners). In this paper, wepresent the interactive concept cartoon instrument and report on the study. Theresults indicate that learners are engaged when working with the instrument andlearn relevant knowledge regarding the subject matter and the Nature of Science.
Computers are promising tools for providing educational experiences that meet individual learning needs. However, delivering this promise in practice is challenging, particularly when automated feedback is essential and the learning extends beyond using traditional methods such as writing and solving mathematics problems. We hypothesize that interactive knowledge representations can be deployed to address this challenge. Knowledge representations differ markedly from concept maps. Where the latter uses nodes (concepts) and arcs (links between concepts), a knowledge representation is based on an ontology that facilitates automated reasoning. By adjusting this reasoning towards interacting with learners for the benefit of learning, a new class of educational instruments emerges. In this contribution, we present three projects that use an interactive knowledge representation as their foundation. DynaLearn supports learners in acquiring system thinking skills. Minds-On helps learners to deepen their understanding of phenomena while performing experiments. Interactive Concept Cartoons engage learners in a science-based discussion about controversial topics. Each of these approaches has been developed iteratively in collaboration with teachers and tested in real classrooms, resulting in a suite of lessons available online. Evaluation studies involving pre-/post-tests and action-log data show that learners are easily capable of working with these educational instruments and that the instruments thus enable a semi-automated approach to constructive learning.
