Classroom Implementation of Context‐based Chemistry Education by Teachers: The relation between experiences of teachers and the design of materials

Worldwide, a tendency is visible in which upper secondary science curricula are innovated in the direction of context‐based education. Crucial to these innovations is the way teachers interact with newly developed teaching materials and implement them in classroom practice. The focus of our research is to identify characteristics of the interaction between innovative context‐based materials and teachers that hinder or facilitate classroom implementation as intended by the designers. Four cases of classroom implementation by four experienced teachers with different degrees of experiences in context‐based education, all implementing ‘Chemie im Kontext’ (CHiK) teaching materials, were carried out using a previously developed framework for analysis. It was found that a crucial aspect of CHiK, that of taking students' questions and using them as an orientation as the ‘focal event’ for the following lessons, was difficult to implement. The employed contexts are too general and broad to be effectively applicable as a setting in which activities such as students developing their own ideas and exploring them logically take place. Therefore, it is recommended that extensive teacher professionalization is required on this aspect to show teachers its value and to increase their repertoire of necessary teaching activities.     

Mapping context-based learning environments: The construction of an instrument

The current trend in science curricula is to adopt a context-based pedagogical approach to teaching. New study materials for this innovation are often designed by teachers working with university experts. In this article, it is proposed that teachers need to acquire corresponding teaching competences to create a context-based learning environment. These competences comprise an adequate emphasis, context establishment, concept transfer, support of student active learning, (re-)design of context-based materials, and assistance in implementation of the innovation. The implementation of context-based education would benefit from an instrument that maps these competences. The construction and validation of such an instrument (mixed-methods approach) to measure the context-based learning environment is described in this paper. The composite instrument was tested in a pilot study among 8 teachers and 162 students who use context-based materials in their classrooms. The instrument’s reliability was established and correlating data sources in the composite instrument were identified. Various aspects of validity were addressed and found to be supported by the data obtained. As expected, the instrument revealed that context-based teaching competence is more prominently visible in teachers with experience in designing context-based materials, confirming the instrument’s validity.     

Assessors’ approaches to portfolio assessment in Assessment of Prior Learning procedures

In an effort to gain better understanding of the assessment of prior informal and non‐formal learning, this article explores assessors’ approaches to portfolio assessment. Through this portfolio assessment, candidates had requested exemptions from specific courses within an educational programme or admission to the programme based on their prior learning. The assessors judged the portfolios according to set rating criteria, and subsequently discussed their approaches. Their decision‐making processes, perception of portfolio use in the Assessment of Prior Learning (APL), deciding factors in portfolio assessment and use of the rating criteria were key elements in this discussion. The results show that they do use the rating criteria as an indicator in decision‐making, but have mixed perceptions regarding the fairness of APL portfolio assessment. They perceive the portfolio evidence in combination with sound argumentation as the deciding elements in portfolio assessment.     

Measuring teachers' pedagogical content knowledge in primary technology education

Pedagogical content knowledge is found to be a crucial part of the knowledge base for teaching. Studies in the field of primary technology education showed that this domain of teacher knowledge is related to pupils' increased learning, motivation, and interest. The common methods to investigate teachers' pedagogical content knowledge are often complicated, and time and labour consuming. Hence, a challenge in measuring teachers' pedagogical content knowledge is to construct an instrument that is time and labour‐efficient, and makes it possible to investigate large sample sizes. This paper illustrates how a multiple‐choice test to measure teachers' pedagogical content knowledge in primary technology education was designed and validated. The procedure of test construction and the first results are presented. It is concluded that the systematic procedure that was followed is effective for the construction of a valid test. In addition, statistical analyses showed that test/re‐test reliability is moderate. Data collection with larger samples is needed in order to find more statistical support for the psychometric properties of the test.     

English‐medium Content Courses in Non‐English Higher Education: a study of lecturer experiences and teaching behaviours

Abstract

One important factor concerning the internationalization of higher education might be the adoption of a common language as the medium of instruction. For non‐English speaking countries this language tends to be English. Though educational institutions in Europe have already started to conduct (parts of) their curricula in English it is still not clear what effects this change of instructional language will have either on the lecturers involved or on the quality of their instruction. The present article is an attempt to provide an answer to these questions, based on Dutch experiences.     

English proficiency and academic success in international postgraduate education

In the Netherlands internationalization of higher education may lead to an increasing use of a foreign language-for example English-as the medium of instruction. This may raise the issue whether learning in a foreign language affects academic performance, given the language problems international students are faced with when studying abroad. The present article reviews research in this field and presents a study into the academic achievement of 90 Indonesian engineers. These subjects took a one-year English-medium postgraduate course at the International Institute for Hydraulics and Environmental Engineering in Delft. Language proficiency was measured by TOEFL and academic success was defined as the average score on seven written examinations. A most remarkable finding is the observation of a cut-off point in the relationship between English proficiency and academic success. This has led to the hypothesis that there is a range of TOEFL scores within which a better command of English increases the chance of being academically successful. The lower and upper limits of this range may vary according to academic discipline or may even be institution-specific. Additional findings are presented as well as implications and directions for further research.     

Facilitating the learning process in design-based learning practices: an investigation of teachers’ actions in supervising students

Background: In research on design-based learning (DBL), inadequate attention is paid to the role the teacher plays in supervising students in gathering and applying knowledge to design artifacts, systems, and innovative solutions in higher education.

Purpose: In this study, we examine whether teacher actions we previously identified in the DBL literature as important in facilitating learning processes and student supervision are present in current DBL engineering practices.

Sample: The sample (N=16) consisted of teachers and supervisors in two engineering study programs at a university of technology: mechanical and electrical engineering. We selected randomly teachers from freshman and second-year bachelor DBL projects responsible for student supervision and assessment.

Design and method: Interviews with teachers, and interviews and observations of supervisors were used to examine how supervision and facilitation actions are applied according to the DBL framework.

Results: Major findings indicate that formulating questions is the most common practice seen in facilitating learning in open-ended engineering design environments. Furthermore, other DBL actions we expected to see based upon the literature were seldom observed in the coaching practices within these two programs.

Conclusions: Professionalization of teachers in supervising students need to include methods to scaffold learning by supporting students in reflecting and in providing formative feedback.     

Professional development for design-based learning in engineering education: a case study

Design-based learning (DBL) is an educational approach in which students gather and apply theoretical knowledge to solve design problems. In this study, we examined how critical DBL dimensions (project characteristics, design elements, the teacher's role, assessment, and social context) are applied by teachers in the redesign of DBL projects. We conducted an intervention for the professional development of the DBL teachers in the Mechanical Engineering and the Electrical Engineering departments. We used the Experiential Learning Cycle as an educational model for the professionalisation programme. The findings show that the programme encouraged teachers to apply the DBL theoretical framework. However, there are some limitations with regard to specific project characteristics. Further research into supporting teachers to develop open-ended and multidisciplinary activities in the projects that support learning is recommended.     

The effects of a competency‐oriented learning environment and tutor feedback on students’ reflection skills

This study investigates the effects of a competency‐oriented course and the effects of feedback training on students’ reflection skills. Thirty‐one nursing students enrolled in a conventional course with lectures and assignments following a traditional test. Subsequently, they enrolled in a competency‐oriented course, which included more performance‐oriented tasks based on competencies and a performance‐based assessment. In both courses, half of the students received feedback on their assignments from tutors who were trained in feedback skills (experimental group), while the other half of the students received feedback from non‐trained tutors (control group). After each course, all students wrote a reflection report. Results show that students’ reflection reports after the competency‐oriented course were of a higher quality than the reports after the conventional course. Contrary to our expectations, the quality of the reflection reports of the control group (students supervised by non‐trained tutors) was significantly higher than the quality of reflection reports of the experimental group (students supervised by trained tutors). This study shows that a competency‐oriented design of courses enhances students’ reflection skills, but that the training in feedback skills needs to be reconsidered.
