Students' Perceptions of Teaching in Context-based and Traditional Chemistry Classrooms: Comparing content,learning activities,and interpersonal perspectives

Context-based curriculum reforms in chemistry education are thought to bring greater diversity to the ways in which chemistry teachers organize their teaching. First and foremost, students are expected to perceive this diversity. However, empirical research on how students perceive their teacher's teaching in context-based chemistry classrooms, and whether this teaching differs from traditional chemistry lessons, is scarce. This study aims to develop our understanding of what teaching looks like, according to students, in context-based chemistry classrooms compared with traditional chemistry classrooms. As such, it might also provide a better understanding of whether teachers implement and attain the intentions of curriculum developers. To study teacher behaviour we used three theoretical perspectives deemed to be important for student learning: a content perspective, a learning activities perspective, and an interpersonal perspective. Data were collected from 480 students in 24 secondary chemistry classes in the Netherlands. Our findings suggest that, according to the students, the changes in teaching in context-based chemistry classrooms imply a lessening of the emphasis on fundamental chemistry and the use of a teacher-centred approach, compared with traditional chemistry classrooms. However, teachers in context-based chemistry classrooms seem not to display more ‘context-based’ teaching behaviour, such as emphasizing the relation between chemistry, technology, and society and using a student-centred approach. Furthermore, students in context-based chemistry classrooms perceive their teachers as having less interpersonal control and showing less affiliation than teachers in traditional chemistry classrooms. Our findings should be interpreted in the context of former and daily experiences of both teachers and students. As only chemistry is reformed in the schools in which context-based chemistry is implemented, it is challenging for both students and teachers to deal with these reforms.     

The use of video-taped lectures and web-based communications in teaching: A distance-teaching and cross-Atlantic collaboration experiment

We have conducted an experiment to discover how we can co-teach the course 'Engineering Design Problem Formulation' simultaneously at the Delft University of Technology (The Netherlands) and at Carnegie Mellon University (CMU, Pittsburgh, USA). We have formed teams that involved students from both countries, and we have experimented with long distance collaboration. In doing so, students would learn to co-operate with people at another (time zone) location with a different cultural background and, in addition, they would help the teachers of the course to develop insights into long distance collaboration. CMU lectures have been recorded with a digital video camera, and a set of PowerPoint slides accompanied each of these lectures. The movies were used by the Delft teachers by running them in class along with the PowerPoint slides and stopping often to discuss the material as the movie progressed. We also made fourperson international student groups. The entire international group met once at the start of the course using video-conferencing. During the course, the groups communicated through phone calls, e-mails and chatting. In addition, everyone in the course used the web-accessible document management system LIRE' (developed at the Institute for Complex Engineered Systems, CMU) to capture, organize and share all documents anyone produced throughout the course. The tools used in the course and the collaboration experiences were evaluated through a questionnaire distributed among the students. The results are presented in this paper.     

Fostering meaning-oriented learning and deliberate practice in teacher education

Meaning-oriented learning and deliberate practice may be expected to promote student teachers’ continuous professional development. We interviewed twelve expert teacher educators to explore their understanding of these concepts, as well as pedagogies to stimulate them in teacher education. The experts understood deliberate practice in two ways: an enactment conceptualization focusing on pupil learning, and a regulation conceptualization focusing on teacher learning. Pedagogies were operationalized in twelve design principles, which integrated ideas previously scattered in the literature, and added to it with respect to anticipatory reflection, diverse ways of “modeling”, and student teacher agency in creating a powerful learning environment.     

Teacher learning and collaboration in innovative teams

In this study the relationship between teacher learning and collaboration in innovative teams was explored. A comparative case study was conducted in five temporary teams in secondary schools. Several quantitative and qualitative data collection methods were used to examine collaboration, teacher learning, and the context for learning and collaboration. In cross‐site analysis two complementary patterns of teacher learning and collaboration were identified. Collaboration in all teams could be characterized as ‘sharing’. However, sharing was further specified with regard to differences in the content and aims of sharing. Different types of sharing were related to teacher learning. The results give cause to rethink the nature of interdependence in collaboration, and the nature of the relationship between collaboration and learning. A practical result may be that collaboration in innovative, temporary, and voluntary teams could be a promising direction for teacher professional development.     

How do teachers learn in the workplace? An examination of teacher learning activities

In this study, two data collection instruments were used to examine how Dutch secondary school teachers learn in the workplace. Firstly, they completed a questionnaire on their preferences for learning activities on two occasions. Secondly, during the intermediate period, they reported learning experiences in digital logs. Results of both instruments indicate that teachers often learn by critical individual reflection and by involving colleagues in particular challenging or problematic situations. An additional finding concerns the reporting of sequences of learning activities in the digital logs which is clearly different from the focus on single learning activities as found in most literature and as used in the questionnaire. Furthermore, the digital logs provided a fine‐tuning of the concepts of ‘involvement of colleagues’ and ‘experimentation’ in relation to teacher learning. The study concludes with a critical reflection on both data collection instruments. Finally, implications for future research on how teachers learn are discussed.     

Developing and implementing innovative ICT-supported engineering education and educational services: results of a faculty-wide research and implementation programme

This paper describes the results of a department-wide programme called IMAGO, which was aimed at giving information and communication technology (ICT) a more important and effective role in the educational programmes. The underlying assumption was that students are responsible for their own learning process, and that students are considered to be knowledge- and information-intensive workers rather than passive consumers of information, and need to be facilitated as such. In implementing more advanced and innovative ICT applications for supporting the educational processes and for improving the contents of the courses, we have developed and used an implementation approach that was geared towards managing and steering professionals. The approach respects the role of professionals as highly individual and knowledgeable workers, and suggests the use of specific incentives to stimulate those professionals. The approach used has led to successful results and innovations in the areas of educational administrative processes, such as individual and flexible scheduling software, and in the area of the course contents, such as intensive use of ICT to enhance the students' learning process. The results obtained will be distributed to a wider audience in the near future by means of (inter)national collaborations.     

A dialogical approach to conceptualizing teacher identity

In recent attempts to address the notion of teacher identity, scholars have stressed how identity is dynamically evolving, intrinsically related to others, and consists of multiple identities. Though these postmodern characterizations represent radically new perceptions of identity, they are not extensively discussed in relation to previous assumptions on singularity or sameness of teacher identity. The emerging theory of dialogical self in psychology offers a more elaborate approach to teacher identity, conceived of as both unitary and multiple, both continuous and discontinuous, and both individual and social. Based on this approach, teacher identity is re-defined and implications for research are identified.     

Key experiences in student teachers’ development

This study focuses on the question of why student teachers stay in teaching even after a profound ‘practice shock,’ i.e., a shock that in itself seems to characterize the complex and emotionally challenging first year of student teaching. Using a line drawing technique, the study investigates student teachers’ views of their first year of teaching by examining how they picture their development, their key experiences during that development, and the ways in which they coped with these experiences. The results suggest that most student teachers perceive their own development not as a steadily ascending line as is often suggested by research on the development of teachers’ professional identity. Instead, we now surmise that most student teachers view their development as a path with highs and lows that include transformative moments or periods. This relates to the idea of transformative learning and to theories on identity development that suggest people need a crisis for identity development to occur. During such a crisis, we saw that student teachers explicitly reconsidered their connections to teaching and that this reconsideration led to a regained motivation for teaching. It appeared that supervisors or mentor teachers played a significant role in first‐year (student) teachers’ regaining motivation for teaching.     

Textbook Questions in Context-Based and Traditional Chemistry Curricula Analysed from a Content Perspective and a Learning Activities Perspective

In this study, questions in context-based and traditional chemistry textbooks were analysed from two perspectives that are at the heart of chemistry curricula reforms: a content perspective and a learning activities perspective. To analyse these textbook questions, we developed an instrument for each perspective. In total, 971 textbook questions were analysed. Textbook questions in context-based and traditional curricula appeared to differ significantly in their orientation on content and in the activation to engage students in certain learning activities. Although traditional curricula included more questions that stress traditional chemistry content and included more reproductive chemistry questions than context-based curricula, they were not always as traditional as we had expected. Context-based chemistry curricula focused more on chemistry content relating to societal/technological issues and chemistry theory development and also more questions were included that activate students to regulate their own learning. However, context-based chemistry curricula still included a considerable amount of traditional chemistry content and did not focus as much on higher order learning as we had expected. The developed instruments might be helpful in chemistry curricula design to gain insights into the content which is stressed and how students are activated by textbook questions to engage in learning.     

Promoting effective teacher-feedback: from theory to practice through a multiple component trajectory for professional development

This study describes an evaluation of a theory-based trajectory for professional development called FeTiP (Feedback-Theory into Practice) that aims to have an observable effect on teacher classroom behavior. FeTiP is a multicomponent trajectory for professional development and combines several types of interventions. Its goal is to help teachers expand their feedback behavior in the classroom to provide more, and more effective (i.e. learning-enhancing), feedback. We first describe the foundation of FeTiP, with a central focus on how classroom behavior can be influenced by a multicomponent trajectory of professional development, as this is often a major aim in initiatives for the professional development of teachers but is the most difficult to establish. We describe the effects of FeTiP on the feedback behavior of teachers and attempt to explain why these effects occurred.
