In this paper, Harel and Sowder's proof schemes of taxonomy were applied for identifying eighth grade students' learning of proof and proofing. This study aimed to examine what kind of proof schemes are used in geometry and measurement learning areas and student's skills in giving proof and their opinions about proof. Qualitative methods were…

We focus on students' mathematical reasoning in a technology-enhanced collaborative learning environment. We adopt a dialogical approach to analyze students' mathematical reasoning. The participants of this study include six middle school students. The data consist of participants' written productions, dynamic materials, and the transcriptions of…

We discuss the evolution of an instructional unit for supporting prospective elementary and middle grades' teachers' conceptions of fractions as measures. We first studied prospective teachers' conceptions of fractions using a task-based written assessment with discrete, linear, and circle representations. We designed an instructional unit that…

This paper re-validates middle school students' learning progression of the concept of buoyancy (Gao et al., 2020) by using two-time point data. The previous study developed a four-level learning progression based on data collected at a single time point using cross-sectional design. This single-time-point model of learning progression calls for a…

Middle level school teachers commonly measure and monitor students' academic performance, but such is not the case for students' classroom behavior. This is unfortunate, given the rise in students' classroom behavior problems in middle school, especially for students who experience emotional or behavioral disorders. The Classroom Performance…

Although computational thinking has most often been associated with the science, technology, engineering, and math education fields, our research takes a first step toward documenting student outcomes associated with integrating and assessing computational thinking in the social studies. In this study, we pursued an embedded research design,…

Since the turn of the century, China has shown its determination to change its examination-oriented tradition. It started assessment reforms and raised a series of expectations regarding teacher assessment literacy. At the same time, China experienced rapid internal migration, with urban public schools accepting huge numbers of migrant students in…

Preparing students for informed democratic citizenship by learning about contemporary political and social issues requires the ability to critically evaluate online data visualisations. This study examines 25 social studies teachers' perceptions of online data visualisations as informational resources for teaching, and how these perceptions…

This study examines the effects of plugged and unplugged programming tools used in algorithm teaching at the K-12 level on student computational thinking skills and to determine whether gender is a factor in this process. The study group was designed with a control group pre-test--post-test; quasi-experimental model, that consisted of 109 students…

Recognizing that the power of computation has changed the practice of science, science education standards in a number of countries have included a call for the inclusion of computational thinking (CT) in K-12 science education. As CT is a relatively new construct, preparing inservice science teachers to implement CT-infused learning experiences…

This case describes the dilemma of recently hired assistant principal, Fred Bates, who finds himself in a school with a negative and unsupportive school climate. There are significant trust issues between the teachers and principal. Bates struggles to navigate various obstacles and works to establish positive relationships with both his principal…

Research shows that exposure to the outdoors is beneficial to children and can improve the learning experience for students. The Kids in the Woods program in Gainesville, Florida provides 6th grade students with opportunities to learn science through a series of outdoor activities during their regular science classes. The article reports on an…

This design case chronicles the efforts of an interdisciplinary team of researchers as they collaborated with middle grades science teachers and students to build and refine an epidemic disease curriculum module. The initial five-day design was delivered in five science classrooms at three nearby schools where researcher classroom observations and…

The aim of this longitudinal research is to examine the development process of scientific and consistent knowledge structures of first, second, and third-grade students in middle school within the concepts of melting and dissolution according to conceptual change theories at the end of the education and training processes carried out in…

This case study focused on middle school and high school teachers in an independent school to explore their perceptions of how overparenting influenced them in the classroom. A qualitative case study was conducted within an independent school in the southeast United States. Eleven middle school and high school teachers, which represented 52% of…
