The creation and evaluation of known evolutionary histories and the implementation of student investigatory experiences on evolution are difficult endeavors that have only recently been feasible. The research presented in this dissertation is related in their shared use of digital evolution with Avidians as a model study system, both to conduct…

This design case chronicles the efforts of an interdisciplinary team of researchers as they collaborated with middle grades science teachers and students to build and refine an epidemic disease curriculum module. The initial five-day design was delivered in five science classrooms at three nearby schools where researcher classroom observations and…

Engaging students in scientific argumentation is a hallmark of high-quality science instruction. Despite the importance of this practice, it is not a ubiquitous one within K-12 classrooms since scientific argumentation is complex and difficult to learn how to do well. In this study, we examined similarities and differences in how preservice…

The "Next Generation Science Standards" call for engaging K-12 students in three-dimensional learning, in which students make sense of phenomena or solve problems by simultaneously using science and engineering practices (SEPs), crosscutting concepts (CCCs), and disciplinary core ideas (DCIs). Decades of education research suggest…

Inquiry-based science instruction (IBSI) has the potential to contribute to social justice through widening participation and success in science. However, teachers struggle to implement IBSI because of contextual factors. The purpose of this paper is to explore the use of agency as a framework for understanding teachers' decision-making, by asking…

We investigated to what extent secondary school students have insight in the apparent motion of the Sun and stars (AMoSS). We used the AMoSS test instrument, which focuses on distinctions between different aspects of the apparent motion of the Sun and stars. It consists of 12 multiple-choice questions accompanied by explanations. We administered…

Throughout the country, there are many bodies of fresh water affected by algal blooms. By focusing on a water source near their school, students can become scientists, too. Situating science content in real and meaningful learning experiences encourages students to be invested in their own learning, construct deeper understandings, and apply those…

This exploratory case study aims to determine how preschool teachers' epistemological beliefs influence their pedagogical conceptualizations of science teaching. The research was conducted with a total of 10 teachers that were selected among 61 preschool teachers by their epistemological beliefs. The participants were divided into two sub-groups…

Light spectrum dispersion is an exciting subject in science because of its beautiful atmospheric colour phenomenon which attracts students. However, to see the phenomenon is not easy since it needs a spectrometer, which is commonly expensive. Therefore, the present study aims to describe a low-cost spectrometer for investigating lighting spectrum…

Air pollution is one of our day's significant reasons for human health problems and affects every community throughout the world. Monitoring air pollution is a key aspect of raising awareness and pollution mitigation approaches followed by different nations. This paper targets to develop a low-cost Internet of things-based embedded system to…

The flight of a quadcopter drone, readily available as a toy, is analyzed using simple physics concepts. A smartphone with built-in accelerometer and gyroscope was attached to the drone to register the accelerations and angular velocities along the three spatial axis while the drone is taking off, landing or rotating. The vertical speed, the…

The paper introduces an electronic device named 'Blinker', which is suitable for laboratory work on topics related to electric current and resistance, as it allows the visualization of electric current. The Blinker is well suited for all levels of education if the activities are carefully selected. However, despite other devices used for measuring…

The construction of dynamic multimedia products requires the selection and integration of a range of semiotic resources. As an assessment task for preservice teachers, this construction process is complex but has significant potential for learning. To investigate how weaving together multiple representations in such tasks enables learners to…

Marble, formed by the metamorphism of limestone, is commonly used in the construction industry and sculpting. The mineral in marble is either calcite [CaCO[subscript 3]] or dolomite [CaMg(CO[subscript 3])[subscript 2]] or sometimes both. The pure white Carrara marble from Italy was made a household name by Michelangelo, the famous sculptor of the…

As part of their third-year general chemistry program, students at the University of the Côte d'Azur are taught the basics of radioactivity. The view that third-year university students have of the periodic Table of the Elements is often reduced because it ignores the vast majority of isotopes. As part of this program, a practicum devoted to the…
