The overhead mechanical stirrer is a versatile and valuable tool for the laboratory. Even a low-end mechanical stirrer is rather expensive and can pose serious safety concerns for use by high school or undergraduate students. The construction and application of a low-cost overhead mechanical stirrer is described in this work. The mechanical…

Inspired by Freire's principle of dialogue, in this article we present a series of dialogues and critical syntheses between a science teacher-researcher with 35 years of experience and an early-career science teacher-researcher. We explore being in-between academic research in science education and high school teaching. Following Anzaldúa's…

Gender inequality is strongly linked with poor performance in science and mathematics for female students in secondary schools owing to socio-economic and cultural issues as well as learning strategies. According to the Certificate of Secondary Education Examination results of 2021 in Tanzania, the failure rate for female students was higher than…

Augmented reality (AR) has the potential to fundamentally transform science education by making learning of abstract science ideas tangible and engaging. However, little is known about how students interacted with AR technologies and how these interactions may affect learning performance in science laboratories. This study examined high school…

Virtual labs provide space for students to iteratively test, observe, and revise their understanding so as to improve their scientific literacy. However, one of the challenges that students face is that they need to think and act like scientists so as to be sensitively alert to methodological flaws and various sources of error. This study thus…

A distinct education has become a heretical right for urban elites despite educational equality is an official agenda. This has not only widened the gaps between urban and rural counterparts but also developed discriminations amongst different classes of student within the urban schools. To validate this tenet, the facilities offered by various…

National governments are concerned about the disconnection of young people from science, which hampers the development of a scientifically literate society promoting sustainable development, wellbeing, equity, and a green economy. Introduced in 2015 alongside Agenda 2030, the "open schooling" approach aims at enhancing students' science…

Measuring the 3D position at any time of a given object in real-time automatically and well documented to understand a physical phenomenon is essential. Exploring a stereo camera in developing 3D images is very intriguing since a 3D image perception generated by a stereo image may be reprojected back to generate a 3D object position at a specific…

There is a wide variety of ways for instructors to seek to improve diversity, equity, inclusion, and respect (DEIR) in chemistry through their instruction. One way is to talk with students explicitly about equity and injustice in science. We propose a curricular framework for teaching about equity as a way to improve DEIR in science classes at the…

This paper presents the design and reports on the use of a simple and inexpensive cloud chamber kit that is compatible with active learning, experiential learning, and project-based learning strategies. The kit was developed for use in a first-year undergraduate nuclear science seminar class at a university in the US. Diffusion cloud chambers are…

Community driven science has emerged as a way to engage participants in learning about science while giving them a deeper understanding of what it means to do science and identify as one who does science. This multi-method case study investigated how secondary science preservice teachers experienced a community driven science project within the…

Culturally Relevant Education (CRE) focuses on the design of curricular materials that strengthen students' cultural identities while teaching classroom content and science practices. While examples of CRE in science continue to grow, the identities and cultures of the designers are often different from those of the students and communities in…

The purpose of this study was to analyze the effectiveness of scripted biology curriculum as a means of providing students with the information required to increase content knowledge, while comparing curriculum developed by the teacher that utilizesthe Understanding by Design (UbD) framework (Wiggins & McTighe, 2005). The study used a mixed…

Inclusion of a diverse group of students, both regular learners and learners with special needs in chemistry classrooms is an important goal of chemistry educators. However, alternative conceptions in chemistry among high-school students can be a barrier for completing the learning process in the classroom, especially in a heterogeneous class.…

Although Machine Learning (ML) is found practically everywhere, few understand the technology behind it. This presents new challenges to extend computing education by including ML concepts in order to help students to understand its potential and limits and empowering them to become creators of intelligent solutions. Therefore, we developed an…
