This practice-based qualitative case study explored the effective instructional strategies high school teachers use to re-engage the learner in a post-COVID environment. The problem addressed was the lack of effective instructional strategies to re-engage students in the classroom post-pandemic. The theoretical framework used to guide the study…

Science educators are integrating more and more computational thinking (CT) activities into their curricula. Proponents of CT offer two motivations: familiarizing students with a realistic depiction of the computational nature of modern scientific practices and encouraging more students from underrepresented backgrounds to pursue careers in…

This study explores the effectiveness of GeoGebra in enhancing students' understanding of vectors in mathematics education. The research compares traditional teaching methods with the application of GeoGebra to determine its impact on conceptual and procedural knowledge acquisition. Vectors are often challenging for students to grasp due to their…

Traditional rote learning methods often fail to adequately develop reasoning skills in mathematics, particularly among pre-university students. This study addresses challenges in fostering mathematical reasoning abilities, as evidenced by declining TIMSS results and resistance to pedagogical innovations. My online teaching with GeoGebra (MyOT_G+)…

This study examines the impact of integrating GeoGebra software into teaching circle properties at the high school level, comparing it with traditional methods. Conducted over 8 weeks with 112 students aged 15-18, it included an experimental group using GeoGebra (56 students) and a control group with classical teaching methods (56 students). The…

The integration of information and communication tools in education has been a common trend in the last decade which resulted in increased student engagement, motivation, and even achievement and learning. Despite these improvements, science teachers still report challenges with its use in science education. Several abstract topics in chemistry…

The interactive generation of chemical-structure diagrams is an integral activity in the study of chemistry as well as in professional chemistry environments. For educational purposes in particular, the existence of suitable software tools free of charge is of great importance. Although a number of free chemical-drawing applications are currently…

This study investigated how students' and teachers' pedagogical roles in mobile learning moderated the relationship between high school students' perceived usefulness of mobile technology and the actual use frequency, as well as how students' perceived usefulness impacted their physics learning achievement. We examined 803 high school freshmen who…

Blogs are useful interaction tools to promote learners' knowledge construction and interaction in online teaching activities. On the other hand, although many studies show that mindtools facilitate learners' cognitive process, little research focus on their effects on learners' higher order cognitive thinking in blogs. This research developed a…

This paper describes a high school or introductory university course in scientific programming that introduces the computer revolution into the physics curriculum at the beginning. In the first one-hour lecture, Euler's method is presented and used to compute a solution to the analytically unsolvable two-body problem. In the remainder of the…

Digital technologies are essential for almost all human activities, so children should learn to work with them at schools. Some studies of the effect of using computers, tablets or cell phones at schools have been carried out, but in Czechia, where the research was conducted, the number of such studies is very low. We wanted to examine how tablets…

This study investigates designs for developing knowledge building (KB) and higher order competencies among academically low-achieving students. Thirty-seven low-achieving students from a ninth-grade visual arts course in Hong Kong participated. The design involved principle-based KB pedagogy, with students writing on Knowledge Forum® (KF),…

In modern school education, the integration of technology has revolutionized traditional teaching methods and introduced innovative approaches to curriculum design. Class blogs and student blogs have emerged as dynamic web 2.0 tools that hold immense potential to transform the learning experience in schools. This abstract explores the utilization…

In Costa Rica, before 2016 the subject of statistics was not included in the national high school tests in Mathematics. As of 2016, the test, consisting of 60 items, includes 9 statistical items. On the other hand, teachers in their lessons usually use traditional expository methods, mediated by the use of a blackboard and printed materials. In…

The number of computer science (CS) courses has been dramatically expanding in U.S. high schools (HS). In comparison with well-established courses in mathematics and science, little is known about how the decisions made by HS CS teachers regarding how and what to teach impact student performance later in introductory college CS courses. Drawing on…
