This study aimed at investigating the effectiveness of using Radioactivity Remote Laboratory Activities (RRLAs) in enhancing Form Four (equivalent to Grade 10) students' understanding of radioactivity and motivation to learn science. For this purpose, in this study, a repeated measures one-way ANOVA design was utilized in which 54 Form Four…

Curriculum materials can play a major role in shaping teachers' thinking about instruction and content as well as serve as a support for teachers' learning. With the inclusion of engineering in NGSS, many teachers may be turning to existing curriculum materials to help them infuse engineering into their science classroom, especially when they do…

To examine differences between sequences of secondary science courses on achievement on science high stakes exams, a purposive quantitative research design was utilized in this study. A short survey was sent out to public high schools in the state of Missouri that asked to identify their main science course sequence. In addition, participants were…

A common misconception about dissolving is that heating and/or stirring are required for the dissolving process to occur. In this study, quantitative experimental evidence was collected and analyzed to demonstrate that neither heating nor stirring is required for dissolving. Educators can use the data and results in this study to address this…

In the spring of 2018 the Northern California/Nevada Section of the American Association of Physics Teachers was alerted to a local high school's plans to eliminate physics for the following school year. As part of the campaign to support the school's efforts to sustain physics in the following year, the physics offerings from the surrounding…

Described here is a well established opensource geophysics project to monitor atmospheric infrasound 24/7. It employs a modern digital, I[superscript 2]C enabled differential pressure sensor--unlike the older analog devices more commonly used. Python software automatically uploads plots whilst data is stored in standard ".mseed" format…

The private company SpaceX regularly launches satellites into geostationary orbits. SpaceX posts videos of these flights with telemetry data displaying the time from launch, altitude, and rocket speed in real time. In this paper this telemetry information is used to determine the velocity boost of the rocket as it leaves its circular parking orbit…

In this article, we describe the main phases in the development and validation of a questionnaire measuring secondary students' teleology and essentialism conceptions in the context of genetics. The validation process involved 714 Swiss and French secondary school students from 14 different schools. The process included interviews, several pilot…

Incorporating scientific uncertainty as part of science teaching means acknowledging that there may be incomplete or potentially limited scientific information when scientists draw conclusions. In the geosciences, scientists routinely make inferences about the Earth based on observations of the present, and test those observations against…

Dark matter comprises most of the matter in the universe, yet physicists are unsure of its nature. A significant effort is devoted in contemporary research to attempts to understand dark matter, making it a both captivating and relevant area of astrophysics to discuss in a classroom setting. What is more, the physics behind these experiments is…

The analysis of the Test Instruments' quality is a crucial thing needs to be conducted. The test instruments made by teachers must fulfil the requirements (validity, reliability, and standard error of measurement) until the measurement result obtained can describe the students' actual abilities. This research aims to analyse the content validity…

The study aims to present the development of education in North Macedonia from the country's independence to the present day, as documented in several national reports and other official documents. The focus is on development and changes in chemistry education throughout the years of primary, secondary and higher education. Particular attention is…

The South African Department of Education has attributed the poor pass rates in Grade 12 Physical Sciences to the learners' lack of practical work and the inability of learners to solve problems by integrating their knowledge from different topics in Physical Sciences. A possible reason for this could be a disjointed alignment between the…

Every country's educational policy directs the implementation and success or otherwise of education outcomes. This study analysed some educational policies of the Ministry of Education of Ghana to determine the current state of use of Information and Communication Technologies (ICTs) in science instruction in senior high schools and its…

The main objective of this study is the design and validation of an educational methodological model based on the use of immersive technological resources (Augmented Reality -- AR) to improve learning processes in secondary education science subjects (Biology and Geology). The process was developed based on three main quantitative studies: an…
