Little is known about the leadership educators who work in more than 2,000 leadership programs worldwide. This phenomenological study of 13 experienced leadership educators from four states and 11 universities explored the lived experiences of becoming and being a leadership educator in higher education. Four sub themes emerged from participants'…

This article provides an overview of a modeling sequence that culminates in student reinvention of a bifurcation diagram. The sequence is the result of years of classroom-based research and curriculum development grounded in the instructional design theory of Realistic Mathematics Education. The sequence of modeling tasks and examples of student…

This paper was inspired by the work of a previous contributor on the subject of modelling plague epidemiology by comparing it to the physics of series radioactive decay, RC transients, and fluid dynamics. An Arduino-based experiment to illustrate the fluid-dynamical case is described. Attention is drawn to important differences between systems…

As part of their professional competencies, science teachers need an elaborate meta-modelling knowledge as well as modelling skills in order to guide and monitor modelling practices of their students. However, qualitative studies about (pre-service) science teachers' modelling practices are rare. This study provides a category system which is…

The Republic of Korea is well known as a leader of gifted science education due to the significant progress it has made in the past two decades. This paper aims to provide a historical perspective of gifted science education in Korea by interviewing a key figure in the Korean science education community. This paper explores the various…

Understanding the nature and purpose of models, including mathematical models, is critical to enabling undergraduate chemistry students to use models to predict and explain phenomena. However, students often do not have systematic conceptions about different kinds of models. To gain a sense of how students understand different models in the…

This paper describes a faculty development project in which four teacher educators, who were part of a larger Faculty Learning Community, used an innovative model called the Faculty Learning Lab to support each other in critical reflections about their teaching. Within the learning lab, which was guided by Knowles' adult learning theory, each…

Motivation cannot be measured directly but has to be evaluated through other indirect measurements, of which questionnaires are the most common. This chapter presents the results from the development and use of a model to approach motivation in the science classroom from multiple theoretical and methodological perspectives. The model emerged from…

Teaching and learning pronunciation can be challenging for second language (L2) teachers and learners alike. Many people may even adopt that attitude that, 'She'll be right', thinking that L2 learners' pronunciation difficulties will likely sort themselves out in time. Yet many learners consider pronunciation to be the most difficult oral…

Green skills need to be developed in vocational education for sustainable future. However, the vocational high school curriculum of agricultural food processing technology in Indonesia does not explicitly state the development of green skills. Teaching materials, such as module are needed to develop vocational students' green skills. This study…

Assessments built on a theory of learning progressions are promising formative tools to support learning and teaching. The quality and usefulness of those assessments depend, in large part, on the validity of the theory-informed inferences about student learning made from the assessment results. In this study, we introduced an approach to address…

Mathematical modeling has been recognized and highlighted in most standards and reports as an important concept to the teaching and learning of mathematics. The study investigated 208 PK-8 preservice teachers' (PSTs') familiarity and experiences with mathematical modeling. The study adopted a survey-design perspective to collect data from 10…

Pre-service mathematics teacher (PST) education often addresses within Geometry Classes how to utilize Dynamic Geometric Software (DGS). Other classes may also incorporate teaching pre-service teachers about the history of mathematics. Although research has documented the use of Dynamic Geometric Software (DGS) in teaching the history of…

Making public school accommodating of all learners such that the need for special education is obviated, or at least reduced, has long been a desideratum of educators. Various strategies for making general public education more accommodating of students with disabilities have been tried. The most recent efforts to improve the general education of…

In this work, we discuss the importance of underlying theoretical assumptions in research, focusing on the conclusions reached when analyzing data from a misconceptions constructivist (stable, unitary) perspective in contrast to a fine-grained constructivist (resources, knowledge-in-pieces) perspective. Both frameworks are rooted in the idea that…
