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…

This article reports on how increasing understanding of the morphology of science vocabulary, by introducing and using affixes, improved students' ability to recognise key words in examination questions and link these to prior knowledge. As a result, students attempted far more questions and the quality of answers they provided was significantly…

Academic vocabulary networks were examined in 3 elementary grades textbook programs (first through fifth grade) in 3 domains--science, mathematics, and social studies. Within each program, a given network consisted of a focal domain-specific academic word and the collection of words from all grades that overlapped in meaning with the focal word.…

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…

Students struggle with observing scientifically and connecting observations to scientific theory. This study investigates how students actually use observation in rock classification -- a classical practical task in science education. To describe the level of students' use of observation, data was collected by videotaping 19 small student groups…

The main purpose of this study is to explore the epistemological problems underlying pre-service chemistry teachers' aims in using practical work, "i.e.," individual or small group object manipulation or observation, in school science. Twenty-two pre-service chemistry teachers participated in this study. Qualitative data collection tools…

Many teachers struggle to provide equitable opportunities for students with special educational needs (SEN) to learn science concepts in the inclusive classroom. This study examines the experience of teaching in an inclusive classroom using a conceptual change approach, the Thinking Frames Approach (TFA), incorporating the use of discrepant…

Research-based assessment instruments (RBAIs) are ubiquitous throughout both physics instruction and physics education research. The vast majority of analyses involving student responses to RBAI questions have focused on whether or not a student selects correct answers and using correctness to measure growth. This approach often undervalues the…

This study explores the effect of problem-based learning on students' lateral thinking skills in biology subjects, the concept of environmental change. This quantitative research uses a quasi-experimental model with a pre-test post-test control group design. The population in this study were students of class X MIPA Integrated High School Riyadlul…

The ability to separate, identify, and quantify proteins from complex mixtures are key foundational methods across biochemistry teaching and research. In particular, enzyme-linked immunosorbent assay (ELISA) is an important technique that is used to measure antigen concentrations in both industry and academia. There are four categories of ELISA,…

With calls to reassess higher education teaching methods, active learning practices have quickly become a popular alternative to traditional lectures, especially in STEM courses that traditionally rely heavily on large-lecture formats. In this regard, active learning environments stand to better prepare students for life after college; however,…

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…

This study aimed at investigating the issue of domain specificity of motivation across specific science disciplines (chemistry and physics) in combination with influencing factors related with students' academic major and gender. A clustered sampling was used to select 281 participants who were undergraduate students (105 males and 176 females)…

The use of smartphones in experimental physics is by now widely accepted and documented. PASCO scientific's smart cart, in combination with student-owned smartphones and free apps, has opened up a new universe of low-cost experiments that have traditionally required cumbersome and expensive equipment. In this paper we demonstrate the simplicity,…

Attracting more students to the geosciences is imperative. We have an excellent opportunity to model an inclusive community, with hundreds of thousands of students passing through introductory college courses each year. A previous study documented gender and racial bias in physical geology textbooks. Six texts were reexamined to determine any…
