How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

Most recently, there has been a noticeable rise in the push for use of technology in the classroom. The advancement in digital science has increased greatly the capacity to explore animations, models, and interesting apps. that should substantially enhance science cognition. At the same time, there is a great need to increase collaboration in the…

We examined the interactions among pedagogical content knowledge (PCK) components of novice and experienced chemistry teachers in teaching reaction rate and chemical equilibrium topics in this qualitative multiple-case design study. For this aim, three chemistry teachers who had different levels of teaching experience in chemistry teaching were…

This research aims at revealing (1) the suitability of physics e-scaffolding teaching media with mathematical and image/diagrammatic representation, as well as (2) the effectiveness of the e-scaffolding teaching media with mathematical and image/diagrammatic representation to improve students' problem solving ability and scientific attitude. It is…

This study investigated the response of students and teachers to the use of ICTs to promote teaching and learning outside of the classroom and regular school hours in a Caribbean secondary school. Following an action research design, Grades 10 and 11 Biology students were given access to subject content and learning support through online…

In this qualitative case study, we examined the nature of integration among pedagogical content knowledge (PCK) components. To attain the goal, two experienced chemistry teachers' teaching redox reactions and electrochemical cells was observed. The data were collected through card-sorting activity, content representation (CoRe) tool, observation,…

The way in which education is taught is forever changing. Therefore, a new method in which content is delivered is a central component in examining areas for improvement. In this paper, participatory action research (PAR) was used to investigate authentic tasks in the inclusive tenth and eleventh grade classroom. The purpose of this study was to…

In this paper we aim to establish a link between two theoretical frames: modelling and its use in the design and analysis of scientific teaching sequences, and the communicative approaches as they alternate in classroom activities. In this case study, we follow the interactions between the teacher and a pair of students during an entire teaching…

Most academic science educators encourage teachers to provide their students with access to more authentic science activities. What can and do teachers say to increase students' interests in participating in opportunities to do real science? What are the discursive "resources" they draw on to introduce authentic science to students? The purpose of…

The state of mathematics and science education in South Africa is a cause for concern. This situation can be attributed, in part, to many mathematics and science teachers' limited content knowledge, ineffective teaching approaches, and unprofessional attitudes. To address these three problem areas simultaneously, a holistic model for the…
