Explicit teaching and scaffolding to enhance concept learning by design challenges

This paper presents a mixed methods study in which 21 first-year student teachers took part that investigated learning outcomes of a modified learning by design task. The study is part of a series of studies that aims to improve student learning, teaching skills and teacher training. Design-based science challenges are reasonably successful project-based approaches for breaking down the boundaries between traditional school subjects. Previous learning outcomes of the extensively studied Learning by Design (LBD) approach demonstrated a strong positive effect on students’ skills. However, compared to traditional classroom settings, LBD provided little or no profit on (scientific) concept learning. For this, according to two preliminary studies, a lack of explicit teaching and scaffolding strategies, both strongly teacher-dependent, bears a share of responsibility. The results of this third study indicate that more emphasis on these strategies indeed strengthens concept learning without reducing positive effects on skill performance.

Teachers’ use of inquiry and language scaffolding questions when preparing an experiment

This study analyze data from three national contexts in which teachers worked with the same teaching materials and inquiry classroom activities, investigating teachers’ use of strategies to promote interaction and scaffolding when participating in a professional development program. The data material is collected from three case studies from the Netherlands, Norway, and Sweden, respectively. Each case is from a teaching unit about green plants and seed sprouting. In one lesson in this unit, students were involved in planning an experiment with sprouting seeds, and this (similar) lesson was videotaped in three national settings. The main research question is, as follows: How do primary teachers use questions to scaffold conceptual understanding and language use in inquiry science activities? The data analysis shows that teachers ask different kind of questions such as open, closed, influencing and orienting questions. The open, orienting questions induce students to generate their own ideas, while closed orienting and influencing questions often scaffold language and content-specific meaning-making. However, both open, closed, orienting and influencing questions can scaffold student language and conceptual understanding. Often, teacher questions scaffold both language content-specific meaning-making at the same time. The study shows the subtle mechanisms through which teachers can use questions to scaffold student science literacy and thereby including them in classroom interaction.

Scaffolding genre-based writing in the subjects

To promote student writing development, integrated approaches such as genre-based writing instruction (GBWI) are advocated in tertiary education. However, most subject lecturers are not used to centralise writing in their subjects as they focus on content teaching. Capitalising on teacher learning within GBWI is therefore necessary. Design-based research can offer a fruitful learning environment for such innovative type of content and language integrated instruction. In a multiple case study (n=2) in Dutch higher professional education, we aimed to explore what subject lecturers can learn in a design-based research project in terms of scaffolding students’ writing. Qualitative data on teacher learning were collected through logs and interviews before, during and after three GBWI interventions. These data were transcribed verbatim and analyzed using transcription software. Results showed the subject lecturers reported multifaceted learning outcomes, particularly concerning changed knowledge and beliefs. Some of these were directly related to GBWI (e.g., metalanguage, deconstruction, text features) whereas others were related to scaffolding language in subject learning more generally, and to the lecturers’ teaching roles. Both lecturers also reported learning outcomes in terms of changed practices, but to a lesser extent. This may be related to the challenging character of enacting GBWI in the subjects. On a more general level, this study has yielded valuable insights into what factors are at stake when subject lecturers learn to enact GBWI. Further, it has shown the potential of a design-based research learning environment which we view as part of a causal field instigating subject lecturers’ professional development.

Scaffolding primary teachers in designing and enacting language-oriented science lessons

The purpose of the design-based research reported here is to show – as a proof of principle – how the idea of scaffolding can be used to support primary teachers in a professional development programme (PDP) to design and enact language-oriented science lessons. The PDP consisted of six sessions of 2.5 h each in which twelve primary school teachers took part over a period of six months. It centralised the language support that pupils need to reason during science lessons. In line with the idea of scaffolding, the structure of the PDP targeted teachers' gradual independence in designing lessons. The first research question is how scaffolding was enacted during the PDP. The analysis of video recordings, field notes, researcher and teacher logs, and teacher design assignments focused on the enactment of three scaffolding characteristics: diagnosis, responsiveness and handover to independence. The second research question concerns what teachers learned from the participation in the PDP that followed a scaffolding approach. The data analysis illustrates that these teachers had learned much in terms of designing and enacting language-oriented science lessons. In terms of diagnosis and responsiveness, our PDP approach was successful, but we problematise the ideal of scaffolding approaches focused on handover to independence.
