Novel computational approaches for ratio distributions with an application to Hake's ratio in effect size measurement

Ratio statistics and distributions are fundamental in various disciplines, including linear regression, metrology, nuclear physics, operations research, econometrics, biostatistics, genetics, and engineering. In this work, we introduce two novel computational approaches for evaluating ratio distributions using open data science tools and modern numerical quadratures. The first approach employs 1D double exponential quadrature of the Mellin convolution with/without barycentric interpolation, which is a very fast and efficient quadrature technique. The second approach utilizes 2D vectorized Broda-Khan numerical inversion of characteristic functions. It offers broader applicability by not requiring knowledge of PDFs or the independence of ratio constituents. The pilot numerical study, conducted in the context of Hake's ratio - a widely used measure of effect size and educational effectiveness in physics education - demonstrates the proposed methods' speed, accuracy, and reliability. The analytical and numerical explorations also provide more clarifying insight into the theoretical and empirical properties of Hake's ratio distribution. The proposed methods appear promising in a robust framework for fast and exact ratio distribution computations beyond normal random variables, with potential applications in multidimensional statistics and uncertainty analysis in metrology, where precise and reliable data handling is essential.

Blended learning: A data-literate science teacher is a better teacher

The COVID-19 pandemic has underscored the importance of blended learning in contemporary physics and, more generally, STEM education. In this contribution, we summarize current pedagogical models of blended learning, such as rotational and flexible non-rotational models, and customizable configurations of physical and virtual learning spaces. With the inevitable integration of digital technology as one of the pillars of blended learning, teachers find themselves in an unprecedented position to not only obtain data more frequently but also analyze it and adjust instruction accordingly. Consequently, we discuss a crucial element of blended learning effectiveness: data management and usage. In this context, data literacy for teaching emerges as an essential skill for effective blended learning, encompassing the ability to transform various data types into actionable instructional knowledge and practices. In other words, current research in physics education shows that a data-literate science teacher is a more prosperous and effective teacher.

Innovative approaches to high school physics competitions: Harnessing the power of AI and open science

High school physics competitions serve as a platform for talented students to showcase their skills, engage in challenging problems, and foster a passion for science. This paper explores innovative approaches to enhance these competitions by harnessing the power of open science and artificial intelligence (AI) tools. Particularly we delve into the capabilities of state-of-the-art AI chatbots, i.e. ChatGPT, Bard, Claude, related to problem solving in physics. Together with open science tools like SageMath and Jupyter AI, they have the potential to serve as intelligent, powerful co-pilots, tutors, and assistants in understanding and applying physics, as well as knowledge from connected STEM fields. Furthermore, these innovative approaches can revolutionize high school physics competitions, providing students and their tutors with powerful resources to excel in their scientific pursuits.

Social Reader Perusall -- a Highly Effective Tool and Source of Formative Assessment Data

The contribution provides a detailed exploration of the online platform Perusall as an advanced social annotation technology in teaching and learning STEM disciplines. This exploration is based on the authors' insights and experiences from three years of implementing Perusall at P.J. Šafárik University in Košice, Slovakia. While the concept of social annotation technology and its educational applications are not novel, Perusall's advanced features, including AI and data science reports, enable its use in both synchronous and asynchronous blended and flipped learning environments. In this context, Perusall serves as a digital tool for collecting formative data, monitoring student progress, and identifying areas of difficulty. This assessment data can be effectively utilized in preparing and personalizing subsequent face-to-face group interactions, thereby enhancing and improving the learning experience. From a pedagogical viewpoint, Perusall's role was particularly significant during the Covid-19 pandemic, enabling effective, continuous, and engaging learning amidst social distancing and physical restrictions. Today, Perusall has become a key tool in blended learning, facilitating higher-order cognitive processes during the educational process and, with its multifaceted applications, serves as a modern catalyst in redefining educational experiences and outcomes.

Scientific Computing with Open SageMath not only for Physics Education

Nowadays interactive digital scientific environments have become an integral part of scientific computing in solving various scientific tasks in research, but also STEM education. We introduce SageMath or shortly Sage -- a free open Python-based alternative to the well-known commercial software -- in the frame of our course Methods of Physical Problems Solving for future scientists and science teachers. Particularly, in the 1st illustrative example from the Physics Olympiad, we present Sage as a scientific open data source, symbolic, numerical, and visualization tool. The 2nd example from the Young Physicists' Tournament shows Sage as a multimedia, modeling, and programming tool. By employing SageMath as an open digital environment for scientific computing in the education of all STEM disciplines, teachers and students are empowered not only with a universal educational tool, but a real research tool, enabling them to engage in interactive visualization, modeling, programming, and solving of authentic, complex interdisciplinary problems, thus naturally enhancing their motivation to pursue science in alignment with the core mission of STEM education.
