The United States has a shortage of qualified workers in the science, technology, engineering, and mathematics (STEM) fields (Zhang & Barnett, 2015). There is a critical shortage of underrepresented students seeking science majors and possible science-based careers. The purpose of the study was to examine the perceptions of underrepresented…

This study revisits the seminal question of the effectiveness of education for sustainable development (ESD) by adopting a novel approach. Little is known about the effects of ESD as a teaching approach to develop students' action competence for sustainability. This study therefore adopts a three-wave longitudinal design, tapping into the…

Learners underperform in stoichiometry as they lack conceptual reasoning of the underlying concepts and the ability to solve stoichiometric problems. Therefore, it was necessary to determine if there is a statistical correlation between problem-solving skills and conceptual reasoning in stoichiometry and if so, whether one can significantly…

This study aims to uncover some key elements of successful home-learning of mathematics, based on students' perceptions, during the COVID-19 pandemic and offer recommendations for mathematics learning beyond the crisis. Throughout our work, we aimed to examine students' reflections on mathematics learning and learning environments that assisted…

There are many important questions teachers and administrators need to ask as they grapple with how to ensure high school graduates are college and career ready. What does it mean to prepare students for a world that is rapidly changing--a world in which science and technology are altering how we live, work, play, and interact? If teachers focus…

This study explored students' perceptions of classroom quality in gifted and non-gifted education settings in Saudi Arabia. The researcher used the Zone of Proximal Development theory and Expectancy Value Theory to frame the study. The research was conducted across three public schools (458 students) and two private schools (353 students) that…

We examine the case of a lesson planning session within the context of professional development for dialogic instruction, and the lesson enacted following this session, which was intended to provide opportunities to 11th and 12th grade algebra students to explore polynomial functions in terms of their roots and linear factors. Our goal was,…

This paper reports on an interview study of 18 Grade 10-12 students' model-based reasoning of a chemical reaction: the reaction of magnesium and oxygen at the submicro level. It has been proposed that chemical reactions can be conceptualised using two models: (i) the "particle model," in which a reaction is regarded as the simple…

Energy is a difficult concept to be understood by students of all levels. Thus, the aim of the study is to determine how high school students at different levels perceive the energy and related concepts. In line with this purpose, 173 students in total of which 57 ones of the 9th grade, 94 ones of the 10th grade and 22 ones of the 11th grade…

The purpose of this study was to introduce a rubric named "Rubric for the Assessment of Modeling Skills" for assessing cognitive modeling skills and explaining the rubric's development process. The dimensions of the rubric are understanding the problem, simplifying, mathematizing, working mathematically, interpreting and validating.…

In this study we designed, implemented, and evaluated an outreach programme for high-school biology students rooted in the 'science as inquiry' approach. Accordingly, students learn about science from experts in the field, as well as through in-class exposure to the history and philosophy of science. Our sample consisted of 11th graders (n = 497),…

This report is based on data from the High School Longitudinal Study of 2009 (HSLS:09), a nationally representative, longitudinal study of more than 23,000 ninth-graders in 2009. The cohort was surveyed again in spring 2012 when most students were in the eleventh grade. The 2012 survey included questions about whether students had left their…

There is extensive research in elementary education on effective practices that support academic success for students with mild to moderate disabilities in general education; however there is a dearth of research on high school inclusion practices. A survey examined the current inclusionary practices at a Central Coast High School. California…

We use a natural experiment to evaluate sample selection correction methods' performance. In 2007, Michigan began requiring that all students take a college entrance exam, increasing the exam-taking rate from 64 to 99%. We apply different selection correction methods, using different sets of predictors, to the pre-policy exam score data. We then…

In the context of an analytical geometry, this study considers the mathematical understanding and activity of seven students analyzed simultaneously through two knowledge frameworks: (1) the Van Hiele levels (Van Hiele, 1986, 1999) and register and domain knowledge (Hibert, 1988); and (2) three action frameworks: the SOLO taxonomy (Biggs, 1999;…
