Introduction: Visually impaired students (that is, those who are blind or have low vision) have difficulty accessing curricular material in mathematical textbooks because many mathematics texts have visual images that contain important content information that are not transcribed or described in digital versions of the texts. However, little is…

Chemical equilibrium is one of the most important yet difficult topics to teach. The purpose of this study was to examine how two science teachers experienced the mediation of and how they mediated learning of this topic, chemical equilibrium, to high-achieving students. Data were collected using semi-structured interviews, lesson observations and…

The purpose of this study was, first, to understand the item hierarchy regarding students' understanding of scientific models and modeling (USM). Secondly, this study investigated Taiwanese students' USM progression from 7th to 12th grade, and after participating in a model-based curriculum. The questionnaire items were developed based on 6…

This research investigates the use of student-generated animations in the teaching and learning of chemistry. Previous research has identified the potential for animations to contribute to student learning in science. In particular, animations have the capacity to represent the dynamic process and motions that may be inherent in some chemical…

The purpose of this study was to describe the school climate and school culture in selected public secondary Priority Schools, Focus Schools, and Reward Schools in New Jersey and New York. This study used the United States Department of Education's Elementary and Secondary Education Act (ESEA) Flexibility Waiver definition to identify Priority…

In the spring of 2016 and 2017, a sample of juniors across all Wake County Public School System (WCPSS) high schools was administered a survey of financial literacy concepts as part of the College and Work Readiness Assessment (CWRA). The district administered this survey as education stakeholders have become increasingly interested in--and…

We discuss some aspects of a pilot e-learning technical writing course addressed to 11th grade vocational high school students in Greece. The application of this alternative teaching intervention stemmed from the researcher-instructor's reflections relating to the integration of a problem based e-pedagogy that aims not just to familiarize students…

In this study we present an analysis of how the structure and content of the Greek school textbook approaches the concepts of chemical kinetics, and an investigation of the difficulties that 11th grade Greek students face regarding these concepts. Based on the structure and content of the Greek textbook, a tool was developed and applied to…

Interdisciplinary teaching is a teaching method that is not as easy as other teaching methods to integrate into the everyday school schedule. This paper serves as an example and gives explanations on how this didactic approach can be applied. The lessons described were conducted successfully with a Year 11 class at a secondary school in which the…

This paper is a summary study of team Postgraduate on 11th grade. The objective of this study is to develop a learning model based on problem solving which can construct high-order thinking on the learning mathematics in SMA/MA. The subject of dissemination consists of Students of 11th grade in SMA/MA in 3 kabupaten/kota in North Sumatera, namely:…

In this research paper, I present the reasons why senior secondary students elect not to enrol in a higher mathematics course. All Year 11 and Year 12 mathematics students within Western Australian secondary schools were invited to participate in an online survey comprised chiefly of qualitative items. The key reasons espoused by students include…

This paper focuses on using sociocultural theory to support a context-based approach to teaching mathematics. A goal of the research was to explore the opportunities-to-learn of using a context-based approach to enrich student engagement with mathematics. This paper focuses on the practice of one female secondary school teacher as expressed…

The purpose of this study was to determine if a teacher's Professional Growth and Effectiveness System (PGES) rating is an effective indicator for student achievement. Participants in the study were 9th through 12th grade English 10, Biology, U.S. History and Algebra 2 teachers and students enrolled in their courses. The teacher participants'…

Generalizing is a foundational mathematical practice for the algebra classroom. It entails an act of abstraction and forms the core of algebraic thinking. Kinach (2014) describes two kinds of generalization--by analogy and by extension. This article illustrates how exploration of fractals provides ample opportunity for generalizations of both…

A mysterious conflict of solutions emerged when a group of tenth- and eleventh-grade students were studying a seemingly ordinary problem on combination and probability. By investigating the mysterious "conflicts" caused by multiple randomization procedures, students will gain a deeper understanding of what it means to perform a task…
