The purpose of the current article is to test and revise the hypothetical learning trajectory designed for teaching quadrilaterals by reporting the classroom mathematical practices emerged in a social learning environment developing preservice middle school mathematics teachers' understanding of quadrilaterals. Ten preservice teachers participated…

Background: Inclusive STEM high schools employ a variety of instructional strategies, including PBL (problem and/or project-based learning) experiences, with the goals of building students' 21st century skills, facilitating long-term academic success, and encouraging pursuit of STEM careers. PBL approaches are central to the goals of inclusive…

We designed a professional development (PD) teacher-mentor program that used problem-based learning (PBL) to accomplish two goals. First, teachers explored how PBL could be used effectively in their classrooms to change the way they think about teaching to include literacy development in content areas. Second, PBL was the basis for PD training to…

Taking into account the Science, Technology, Engineering, Mathematics (STEM) integration, it is important to investigate teachers' understandings, perceptions about STEM and how STEM practices should be incorporated into the classroom in order to explore the perceptions of science teachers on this subject and provide important information to…

It has been theorized that contextual tasks support student engagement and sense making. Yet, contradictory ideas exist about the role of these tasks in lessons, and further research is needed to explore how classroom interactions can help achieve their intended purposes. Through video observation of lessons in three eighth-grade classrooms using…

The purpose of this article is to empower those interested in teaching students powerful and engaging social studies. Through the lens of Supreme Court simulations, this article provides educators with a viable, classroom-tested lesson plan to bring Problem-Based Learning into their classrooms. The specific aim of the lesson is to provide students…

This study examines high school students' views of mathematics as a tool for social inquiry in light of their classroom experiences using mathematics to explore social issues. A critical theoretical perspective on mathematics literacy is used to ascertain the ways in which their views challenge or affirm the dominant image of mathematics in…

Studies show that overall seafood consumption in the United States is rising (Agriculture and Agri-Food Canada 2012). Other research estimates that as much as 40% of the seafood caught worldwide is discarded, while countless sharks, whales, dolphins, birds, sea turtles, and other animals are unintentionally killed or injured by fishing gear…

In a regional gathering called the Youth Water Summit, high school students present projects that respond to the driving question behind their science curriculum: "How can you address a significant water resource challenge in your community's watershed?" Students exhibit scientific posters, interactive presentations, films, art projects,…

The purpose of this study was to investigate the impact of a 2-year professional development model in math and science on the self-efficacy of the teacher and its effects on teacher practice and student outcomes. Further, this study sought to incorporate the instructional use of Inquiry-Based Learning methods of Problem-Based Learning, Japanese…

Attempts at integrating mathematics and science have been made previously but no definitive, widely adopted teaching model has been developed to date. Research suggests that hands-on, practical, student-centred tasks should form a central element when designing an effective model for the integration of mathematics and science. Aided by this…

Science and mathematics achievement gaps along racial, ethnic, linguistic, and socioeconomic lines have widened substantially over the past 20 years. Historically marginalized groups having significantly fewer "opportunities to learn" than their more advantaged peers. However, when students from non-mainstream backgrounds receive…

In this paper, we explore some aspects regarding the introduction of an active learning approach to deal with environmental issues in secondary school during natural sciences lessons. Integrated curricular program and PBL (problem-based learning) are comprehensive approaches designed to engage students in investigation of authentic problems. We…

The purpose of the study was to determine the effect of problem-based learning (PBL) on critical thinking ability and content knowledge among selected secondary agriculture students in Missouri. The study employed a quasi-experimental, non-equivalent comparison group design. The treatment consisted of two instructional strategies: problem-based…
