The design of algorithms is one of the hardest topics of high school computer science. This is mainly due to the universality of algorithms as solution methods that guarantee the calculation of a correct solution for all potentially infinitely many instances of an algorithmic problem. The goal of this paper is to present a comprehensible and…

The introduction of large language models (LLMs) may change future pedagogical practices. Current research mainly focuses on the use of LLMs to tutor students, while the exploration of LLMs' potential to assist teachers is limited. Taking high school mathematics as an example, we propose a method that utilizes LLMs to enhance the quality of…

This study explores and analyzes the specific performance of large language models (LLMs) in instructional design, aiming to unveil their potential strengths and possible weaknesses. Recently, the influence of LLMs has gradually increased in multiple fields, yet exploratory research on their application in education remains relatively scarce. In…

Methods: TwoPSTseachtaughtfour6-lessonfrisbeeunitsacrosstwodifferenthighschools.Feedbackonlessonplans prior to teaching, guided reflection-on-action, and repeated teaching was used to support adaptations to six…

Why do some mathematics lessons captivate high school students and others not? This study explores this question by comparing how the content unfolds in the lessons that students rated highest with respect to their aesthetic affordances (e.g., using terms like "intriguing," "surprising") with those the same students rated…

In this study, I documented, analyzed, and compared the thought processes of six high school science teachers during twenty minutes of planning for NGSS-aligned instruction. Teachers' thoughts were captured using a virtual revisit think-aloud protocol and their thoughts were analyzed and compared using a novel tool called a thinking web. A…

Improvement science is a framework which groups can use to identify problems within their sphere of influence, test agreed-upon solutions to those problems, and measure the degree to which those solutions have addressed the problems they intended to change. The pathway groups use to do this work is called Plan-Do-Study-Act Cycles, or PDSA. Much…

This research focuses on enhancing critical thinking in secondary mathematics education using carefully constructed teaching materials. Utilizing socially open-ended framework, complemented by perspectives from critical mathematics education, the study aims to promote students' critical thinking skills. The developed materials were implemented in…

Teacher evaluation systems have evolved over centuries based on how cultures view the profession. Currently, one of the most used evaluation tools is Danielson's framework for teaching (FFT), which has been in use for over 20 years. In this qualitative study, 12 teachers across different high schools shared their experiences of the framework's…

How can creative teaching in economics education be identified and explored? A construct that assists understanding in this area is pedagogical content knowledge (PCK). It represents the merging of content and pedagogy to understand how particular topics or lessons are organised, represented, and adapted to students' diverse interests and…

Research on preservice teachers' (PST) adaptive competence in physical education is critical to prepare them for effective teaching in an ever-changing pedagogical context. This study examined the adaptive competence of two PSTs (one male, one female) during their twelve-week school placement while teaching two 10th-grade classes. The adaptations…

Developing 21st-century skills among students is crucial for their success in college, future careers, and civic engagement. These skills, commonly referred to as the 4Cs (creativity, critical thinking and problem-solving, communication, and collaboration), require teachers to provide tailored learning experiences. This study investigates the…

This paper describes a Lesson Study in which in-service mathematics secondary-school teachers, collaborating with researchers, involve grade 10 students in tessellation problems. The data are collected by an experiment carried out in the context of the "Liceo Matematico" project, with three volunteer teachers. The experiment goal was to…

Current research indicates that inclusive classrooms with students with disabilities are rising, and schools are challenged with shifting their structures and curriculums towards inclusion. This doctoral dissertation aims to understand pre-service program models and how they prepare teachers for inclusive environments, including their knowledge…

By highlighting the curriculum modifications that lead to maintaining, or enhancing, the mathematical quality of an algebra lesson introducing the substitution method for solving systems of equations from an algebra textbook, we present an analysis of how a teacher and her students impact how the mathematical ideas unfold across the lesson and how…
