Augmented reality (AR) technology is increasingly present in chemistry teaching and learning processes. It is seen as an important pedagogical resource that allows enhancing the understanding of complex concepts at most educational levels. However, even though numerous benefits related to AR in education have been reported, no systematic review…

In the context of the current COVID-19 pandemic, we deem of importance the identification of what content is privileged in secondary schools around health and disease. From our point of view, a relevant task is to accompany science teachers in their transit from teaching information to be evoked to teaching knowledge on that content that enables…

The motion equations of a body under gravity and resistance linearly dependent on speed are usually analysed by solving differential equations. In this paper we report a derivation not explicitly involving differential equations but instead based on some elementary mathematical operations. The derivation uses only knowledge covered in a typical…

The typical sound of George Lucas' laser blaster in the "Star Wars" series is well known. What does a laser blaster in "Star Wars" sound like, and why? Here we show a simple way to produce this sound by using low-cost lab material, like a spring or a Slinky. Building on the work of Crawford, who analyzed the sound of a Slinky…

We present a novel method for demonstrating the physical principles of ultrasound imaging at a level suitable for educational programmes up to the university level, using a simple mechanical model that is very inexpensive and accessible to a broad variety of educational institutions. The method revolves around the use of one or two steel springs…

In this paper, we have demonstrated the feasibility of using digital technologies to study the behavior of rubber balloons. The experiment to study the behavior of balloons was presented in a new way using the Vernier measuring system, Logger Pro 3 software, Tracker and Google Sheets. This allowed to significantly optimize the work, reduce…

During the early decades of the 18th century, Newtonian physics was still new. Much effort was expended in testing its validity. One arena in which evidence could be found was the shape of Earth. Was it perfectly spherical? On the observational side there were two hints. In 1671 Jean Richer had measured the rate of ticking of a pendulum clock near…

To a student in introductory physics, using vectors is at best an exercise in bookkeeping. A two-dimensional kinematics problem effectively doubles the number of equations that a student must know, and invites the student to memorize factoids: "The horizontal motion is constant," "Gravity is only in the y-direction," etc. Force…

Students in introductory college physics often have wide ranges of preparation, making it challenging to deliver effective instruction for all. While numerous educational products and strategies have been shown to be broadly effective, there is a need for research-based online materials that support personalized learning and focus specifically on…

For some time, scholars who are guided by critical theories and perspectives have called out how white supremacist ideologies and systemic racism work to (re)produce societal inequities and educational injustices across science learning contexts in the United States. Given the sociopolitical nature of society, schooling, and science education, it…

The purpose of this study is to determine the trend in studies related to Science instruction and ICT. The study has been studied with extensive data, and the data mining method has been used. Some articles entered the ERIC database within the research scope and published in January 2020, starting from 1965. In this context, 1,783,418 articles…

In this study, we aimed to determine metacognition strategies that science teachers use in science lessons and activities they can perform within the scope of these strategies. We used an instrumental qualitative case study design. Research data were collected from science teachers working in public schools during the 2018-2019 academic year. The…

An important facet of inclusive, student-centered science teaching is for college instructors to reveal and respond to student thinking. Professional development (PD) provides formal settings for instructors to develop skills attending and responding to student ideas in their teaching. Using the lens of sociocultural theory, the purpose of this…

Self-regulated learning (SRL) is the metacognitive aspect of learning that goes beyond learning content and skills. With SRL, students are aware of their content understanding and learning progress and use advanced thinking skills to create goals and improve their academic achievement. In this action research, SRL strategies were integrated into…

The sciences are a complex and especially demanding area of study for undergraduate students, particularly in the earlier years, which are a critical period of adaptation to a new educational stage. The use of new teaching models is encouraged to improve their learning, such as flipped classroom (FC), which pursues more meaningful and effective…
