The debate on the use of pesticides is very current in the public media when it comes to topics such as organic farming, bee mortality, and the use of glyphosate. The broad range of pesticide applications and their potential environmental impact makes pesticides an interesting topic for science education in general and for chemistry teaching in…

In chemistry, novices and experts use mental models to simulate and reason about sub-microscopic processes. Animations are thus important tools for learning in chemistry to convey reaction dynamics and molecular motion. While there are many animations available and studies showing the benefit of learning from animations, there are also limitations…

In the course of PISA and TIMSS a lot of out-of-school lab days have been established; as non-formal extracurricular learning environments they shall provide an efficient addition to formal learning at school. The "ELKE" project is a non-formal extracurricular learning lab that aims at linking curricular content and competence-centred…

The aim of the study is to assess the extent to which WhatsApp Instant Messaging is used to teach chemistry and biology to the tenth-grade students. A mixed approach was used, whereby the authors drew on the content analysis model to analyze quantitative data. The sample consisted of 28 Palestinian tenth-grade students and their teachers, who used…

Three projects that use evidence- and research-based practice to engage and support three under-served audiences -- children with special educational needs (Science Hunters -- Lancaster University), young carers (Young Carer Chemistry Workshops at Cotton On -- Science from the Start) and girls and women in engineering (Women Like Me -- UWE…

The purpose of this study is to design an argumentation activity for third-grade students learning about the features defining matter. The research was carried out with seven students who enrolled in a tutoring program in a science and art center in the Eastern Black Sea region of Turkey during the academic year of 2017-2018. The activities were…

The workplace practices of engineers have changed due to the ubiquity of digital technology. So-called techno-mathematical literacies (TmL), seen as a domain specification of 21st-century skills, are essential for future engineers. How these TmL can be fostered in their education, however, is still unclear. To address this issue, we conducted a…

This study aims to identify the obstacles of learning chemistry for ninth grade students in Syrian Arab Republic-Idlib Suburb Refugee camps and suggest solutions to overcome these obstacles. The study followed an analytical descriptive approach using two questionnaires of (58) items of questions for teachers and (18) for students. The population…

This study explored students' perceptions of instructional practices of international teaching assistants (ITAs) who did and did not participate in additional professional development through a Teaching Methods course. The study also sought to understand the components of the Teaching Methods course that supported ITAs in inquiry-based chemistry…

This study aimed to identify the needs of a 10th grade congenitally blind student in an inclusive chemistry classroom and design and develop tactile materials to teach the 'energy in living systems' topic with particular emphasis on covering the symbolic language of the chemistry. A single case study design was used to carry out an in-depth and…

Laboratory experimentation in the context of school science is a widely advocated teaching strategy for the simplification of several abstract scientific concepts. Laboratory-based learning activities have proven to enhance learners' conceptual and procedural understandings of micro chemical phenomena, thus boosting achievement in chemistry…

This paper describes analysis of teaching instances that are part of an in-service preschool teachers programme about chemistry and physics in preschool. The aim is to develop knowledge about the communication established between teacher and children in relation to an object of learning, specifically the role of intersubjective communication in…

We report here a teacher action research project in which a Systems Thinking approach was implemented into a 15 h Depth Study for students in their final year of secondary chemistry. Students were introduced to the concept of Systems Thinking and the use of systems maps, along with the United Nations Global Goals for Sustainable Development…

This study aimed to understand teachers' classroom practices using computer-based simulations (CBS) when teaching electrolysis. The study was framed by the Consensus Model of Pedagogical Content Knowledge. Convenience and purposive sampling were used to select three experienced chemistry teachers from three schools in Eswatini (Swaziland).…

Comprehension of the 3D structure of objects usually represented in 2D is a critical part of understanding molecular geometries. The frequency with which students actually get hands-on with 3D molecular structures is often limited to a singular laboratory session. We sought to develop a set of molecular shapes that were inexpensive enough not only…
