This column provides original articles on innovations in case study teaching, assessment of the method, as well as case studies with teaching notes. This month's issue describes a way of building a library of student-produced videos to use in the flipped classroom.

This manuscript's purpose is to introduce Q as a methodology before providing clarification about the preferred factor analytical choices of centroid and theoretical (hand) rotation. Stephenson, the creator of Q, designated that only these choices allowed for scientific exploration of subjectivity while not violating assumptions associated with…

The Bernoulli's principle states that the quantity p+ pgz + pv[superscript 2]/2 must be conserved in a streamtube if some conditions are matched, namely: steady and irrotational flow of an inviscid and incompressible fluid. In most physics textbooks this result is demonstrated invoking the energy conservation of a fluid material volume at two…

Dancers are continuing to dance longer due to changes in technique and increased awareness of the body and safe movement practices. Even after performing careers have ended, it is healthy both physically and emotionally for dancers to continue to take technique class, particularly if they are teaching dance classes. It can be a challenge, however,…

The B-baby Program is a hip-hop dance curriculum designed to prepare dance instructors to teach and lead toddlers in the safe and effective practice of "break dancing" (breakin'). In 2011, my twin sister and I founded a hip-hop organization called Child of This Culture. We have over 32 years of combined experience as competitive break…

Inspired by Heidegger's philosophy, this article calls for revisiting the role of education and offers an educational goal of examining the meaning of being a human being. Through interpreting the ontological difference, awareness of wholes is suggested as a crucial means for discovering new meanings about ourselves, and Heidegger's perception of…

In a course on chemical applications of symmetry and group theory, students learn to use several useful tools (like character tables, projection operators, and correlation tables), but in the process of learning the mathematical details, they often miss the conceptual big picture about "why" and "how" symmetry leads to the…

The central argument of this essay is that critical literacy with a rationalistic bent may not enable us to cope with ethical dilemmas in our responsiveness to human sufferings. I argue that critical literacy education would benefit from turning to the recent scholarship on affect/emotion studies. I draw upon the works of Sara Ahmed--one of the…

This commentary outlines developments regarding Sex and Relationships Education (SRE, akin to Comprehensive Sex Education) in England and Wales over the past 15 years or so. BZgA has been a WHO/Europe collaborating centre for sexual and reproductive health since 2003. In this capacity, BZgA contributes to the development and dissemination of WHO…

Recruiting adults with autism spectrum disorders (ASD) into research poses particular difficulties; longitudinal studies face additional challenges. This paper reports on a mixed methods study to identify factors influencing the participation in longitudinal autism research of adults with ASD, including those with an intellectual disability, and…

In this article, we analyze theoretical as well as methodological challenges in measuring instructional quality in mathematics classrooms by examining standardized observational instruments. At the beginning, we describe the results of a systematic literature review for determining subject-specific aspects measured in recent lesson studies in…

One of the main challenges for teachers during teaching in class is the diagnosis of students' learning and thinking processes. For this purpose, teachers must perceive relevant information, they need to interpret this information and finally, they need to respond and select suitable opportunities to learn. In this paper, diagnostic processes in…

Teaching about nature of science (NOS) is considered as an important goal of science education in various countries. Extensive empirical research about how some aspects of NOS can be effectively taught is also available. The most widely adopted conceptualization of NOS is based on a small number of general aspects of NOS, which fall into two…

This papers comments on the contributions of "ZDM Mathematics Education" dedicated to the theme "Perception, interpretation and decision making: understanding the missing link between competence and performance". The papers within this issue are brought together under the perspective of the stated aims of this issue, and then…

Because financial literacy is an important skill for middle-grades students, this article suggests numerous personal financial literacy tasks for use in the mathematics classroom. Also provided are specifics for implementing one of these tasks to address mathematical content.
