Curriculum-based professional learning is not just having teachers read curriculum materials, but rather includes carefully crafted experiences to support their sensemaking, deep understanding of the curriculum and its pedagogy, and ability to transfer that knowledge into practice. This instructional model requires that teachers be responsive to…

In the laboratory, data acquisition systems are important, as they allow us to easily and precisely collect data. In this sense, Arduino emerges as an automatic data acquisition device with great potential, due to its low cost and high versatility. In this work, we describe the development of an experimental apparatus, with automatic data…

The use of large, open-source data sets is ubiquitous in scientific research. Scientists--ranging from meteorologists to chemists to epidemiologists--are researching and investigating critical questions using data that they have not themselves collected. To contribute to the growing effort to bring data science into classrooms, the authors have…

In order to increase students' participation in learning activities, a significant role is played by the use of the computer in Geography lessons. The efficiency of computer-assisted learning involves correlation between several essential factors: the quality of online platforms and educational software, the use of appropriate teaching strategies…

When sound waves are taught at the secondary level, the speed of propagation of sound is one of the most important characteristics to be analyzed. However, it is very common in textbooks that the value of sound speed in air is considered constant regardless of the experimental conditions. The great question is that since sound is a mechanical…

More than 60% of U.S. school children are being educated in states in which Next Generation Science Standards or other framework-derived standards have been adopted. This vision demands a central role for students to engage in science and engineering practices to build and use science ideas, rather than solely learning about the science others…

Although there are over 320,000 health and fitness apps available on major app stores, there is scant evidence that they actually promote a healthier lifestyle, assist users in exercising, or promote weight loss. This article presents a lesson plan using an Arduino for integrating computational thinking and game design with middle school students…

The EdHub Library is an online teacher professional development platform that serves 250 school districts as part of the Network for Educator Effectiveness in Missouri. It has a collection of more than 300 online activities. This design case describes the efforts of re-developing EdHub due to technical and usability issues of the first generation…

In the 21st century, the age of information and technology, there is an increasing importance to statistical literacy for everyday life. In addition, education innovation and globalisation in the past decade in Europe has resulted in a new perceived complexity of reality that affected the curriculum and statistics education, with a shift from…

Children love sculpting clay or building sand castles, creating objects in three dimensions before they have the motor skills to draw in two dimensions. Similar arguments applied to the study of curves and graphs in high school mathematics would suggest that students' work and calculation with shapes should move sequentially from concrete to more…

In this paper, we describe how simple experiments realizable by using easily found and low-cost materials allow students to explore quantitatively the magnetic interaction thanks to the help of an Open Source Physics tool, the Tracker Video Analysis software. The static equilibrium of a "column" of permanents magnets is carefully investigated by…

Less than half of the students in the United States graduate from high school and are ready to take college-level math courses. Many years and varieties of remedial math programs have failed to dramatically improve outcomes, especially at scale. The question we face is whether technology in general, and open educational resources in particular,…
