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 article presents a 5E environmental science lesson to help students understand the major environmental factors that lead to acid rain. Students are supported to ask scientific questions to solve the mystery of how acid rain might impact historical buildings. This lesson can be used in a variety of settings both in person and online modalities.…

Stem cell therapy, a cutting-edge technology, aims to replace damaged cells with healthy ones. Stem cells possess the remarkable ability to multiply and differentiate into various cell types, making them ideal candidates for regenerative medicine. This therapy holds promise for treating a wide range of conditions and injuries. In this review, I…

Research has shown that the ways in which teachers engage in professional development activities vary widely. identified three levels of teacher appropriation within professional development, with their inquiry stance indicative of teachers engaging in self-sustaining practices. In our project, we modified the demonstration lesson format so that…

Encouraging students' ability to reason can be looked at through the lens of both oral and written representations. In 2022, the author participated in the first intake of the Teacher Excellence Program run by the Victorian Teaching Academy. Being part of an in-depth professional learning program challenged the author's teaching practices to focus…

Access to drinking water is becoming more limited as drought persists across continents. This article highlights a particularly impacted group of students due to increasing drought conditions and upstream river pollution near their reservation. While there are related water and modeling standards across the K-12 Next Generation Science Standards…

Most teachers try to avoid having students experience uncertainty in their schoolwork. But if we want to prepare students to tackle complex problems (and the uncertainty that accompanies such problems), we must give them learning experiences that involve feeling unsure and sometimes even confused. Beghetto presents five strategies that help…

The English classroom is an indispensable site to critically engage the social complexity of the climate crisis and COVID-19. A question comes up, however, about how to plan for such critical engagement when teaching canonical literature that is seemingly removed from the specific concerns of the current moment. The focus of this article is on…

The fields of quantitative and covariational reasoning boast a wide range of powerful theoretical tools, which are described carefully in the literature. Less frequent and explicit attention, however, has been paid to writing down detailed, practical guidance for operationalizing these theoretical constructs. Some guidance is provided by…

Research shows primary teachers report negative dispositions towards teaching mathematics, impacting their confidence and student outcomes. One approach to improve teacher and student enthusiasm is using picturebooks. While research supports the use of picturebooks in mathematics learning, specific guidance for teachers to implement this practice…

Like terms are usually defined for variables with numerical coefficients. While the definition is sufficient to combine polynomial terms, it does not help the students to combine radical, logarithmic, or trigonometric terms. The purpose of this paper is to propose a lesson that introduces a broader definition of like terms and trialed with a group…

Design thinking--understanding the human needs related to a problem, reframing the problem in human-centric ways, creating many ideas in brainstorming sessions, and adopting a hands-on approach to prototyping and testing--offers a complementary approach to the rational problem-solving methods typically emphasized in business schools. Business…

Social studies professionals advocate linking discipline-based content to citizenship learning goals. However, research suggests that students rarely encounter inquiry-based instruction in their geography coursework and have few opportunities to explore how geography impacts civic decision making. In this article, we present a problem-based…

Providing opportunities for elementary students to engage with enduring social issues, such as houselessness, is essential in preparing informed, engaged, and social justice-oriented citizens. This article draws from the following standards: (1) C3 Framework for Social Studies Standards that center inquiry; (2) Learning for Justice's Social…

A Common Core expectation of high school mathematics students is to analyze functions using different representations. One type of function to be analyzed is piecewise-defined functions. The author has found most approaches to the study of piecewise functions to be abstract, disconnected from any context, and difficult for students to understand.…
