This study examines measurement invariance of student perceptions of teaching quality collected in five countries: Indonesia (n students = 6,331), the Netherlands (n students = 6,738), South Africa (n students = 3,422), South Korea (n students = 6,997) and Spain (n students = 4,676). The administered questionnaire was the My Teacher Questionnaire (...

Increasing informal settlements are characterised by unplanned land management; lack of housing, sanitation, sufficient water and electricity supplies; overpopulation; high health risks; and growing urban poverty. These informal settlements are mostly occupied by citizens and immigrant families who seek job opportunities in urban areas. To sustain...

Effective teaching is a key factor in educational effectiveness and improvement. To facilitate the knowledge exchange regarding effective teaching in secondary education internationally, there has been a growing interest in using classroom observation measures. However, little is known regarding the comparability of observation measures across vari...

The purpose of this study is to examine measurement invariance of scoring of teaching behavior, as perceived by students, across six cultural contexts (Netherlands, Spain, Turkey, South Africa, South Korea, and Indonesia). It also aims to compare perceived teaching behavior across the six countries based on a uniform student measure. Results from m...

Globally, the striving for decolonised education and acknowledgement of a nation's values, skills, beliefs, and acquisition of knowledge is being debated. In science education, the integration of cultural values and beliefs into the science curriculum is often ignored, which contributes to students being unable to express their individual views dur...
Article
Globalization, in the case of science education, leads not only to an increase in homogeneity but also to an increase in cultural encounters. In this study, researchers from 2 distinct cultures, South Africa and Finland, used a qualitative approach to probe student teachers’ perspectives on chemistry education. Participants were 1st-year chemistry...
Article
The need for quality teaching is reflected in the poor performance of students in international tests. Teachers’ practices and contextual factors could contribute to substandard quality of teaching in South Africa. Several studies indicate that successful learning is largely dependent on the teachers’ practices in class. The focus of the present re...
Article
South African teachers encounter numerous challenges in the creation of differentiated activities to include diverse learner needs in effective teaching and learning. These challenges include the inability to identify learning barriers and adapt the curriculum, teaching and assessment methods according to the learning styles and readiness levels of...
Article
Research shows that three-dimensional (3D)-animated lessons can contribute to student teachers’ effective learning and comprehension, regardless of the learning barriers they experience. Student teachers majoring in the subject Life Sciences in General Subject Didactics viewed 3D images of the heart during lectures. The 3D images employed in the le...

Today's children are growing up in an environmentally damaged and technology orientated world. The advent and advances of technology, has resulted in the production of millions of electronic devices, which eventually become waste when they reach their end-of-life. These devices contain toxic components that are not only polluting the environment bu...
Article
Grade 12 Physical Sciences teachers are not always adequately trained to use laboratory equipment to conduct experiments. To address this challenge, this study was based on a combination of traditional methods and technology (a DVD illustrating Physical Sciences experiments) to teach and learn four selected Grade 12 experiments. Student-teachers (n...
Article
Secondary science school teachers (mostly from previously disadvantaged schools where curricula, facilities, and resources do not meet the basic educational needs of learners at these schools) encounter several challenges in developing learners' critical thinking skills. Using critical thinking teaching methods inevitably leads to an increase of th...

Globalization of science education in practice advances a narrow, Euro-American, positivist version of school science. From an educational perspective, culture plays a crucial role in pedagogical values, learning styles, and cognitive processing. One can recognize a strong desire to preserve diversity in response to the threat of loss of cultural i...
Article
The purpose of this study was to ascertain the influence of an extrinsic motivational tool, ‘class-bucks’, on the possibility of improving first year student-teachers’ participation in active learning at Tshwane University of Technology in South Africa. Research participants (n=289) were divided into four classes and engaged in this study during th...

Many first year students enter higher education without the ability to use higher order thinking skills. These students prefer to follow authority, do not question, are not curious and rely on others to think for them. This article reports an action-based study on the implementation and assessment of a structured method to develop critical thinking...

ABSTRACT The ever-increasing population experiences an enormous shortage of skilled scientists that are needed for economic prosperity. Science teachers are important role players to equip students with the skills they need to address the science challenges of the 21st century. The term ‘science process skills’ was propagated by the Science A Proc...

Despite previous research and recommendations in South Africa, secondary-school teachers still encounter economic, social and cultural challenges in implementing differentiated learning activities in the classroom. The diversity of learners with learning barriers inevitably leads to an increase in workload for the teachers. This article draws on da...

Project
With an international perspective and a particular focus on secondary education, we aim to: 1. Investigate and improve the cross-cultural validity of instruments (observations and student questionnaires) measuring teaching practices 2. Enable the possibility of building comparable teaching quality profiles and identifying stages of teacher development worldwide 3. Better understand the precursors of complex teaching pracices (such as differentiated teaching adapted to diverse learners etc.) 4. Document the contexts in which teaching and learning take place in various countries 5. Gain insight into the relationship between teaching practices and student academic engagement (and achievement) in an international context 6. Identify suggestions for effective teacher training and professional development at national at international level.
