The paper explores one episode from a larger study, where a multilingual student (10-year-old) described her understanding of what makes a shape 2D or 3D. Bakhtin's dialogic theory and Garfinkel's ethnomethodology inform the theoretical framework. Transcribed data of the episode is presented, which is analysed at micro-level and macro-level. The…

A new didactical approach named "Learning by Being" (LBB) is proposed and its correlation with current educational paradigms in science teaching is analysed. The key idea in LBB is the assumption by the students of cognitive goals, and three components are mandatory in LBB: a) student's personal learning effort, b) student-teacher mutual…

Humans have long sought to understand the forces that shape the diversity of living creatures on our planet. This work is primarily concerned with examining one such force--the historical action of natural selection--from practical, philosophical, and pedagogical perspectives. The first half is concerned with a suite of genetic mechanisms in…

The paradigm shift from traditional didactic instruction to technology-enriched teaching and learning environments significantly benefits learners. Educational technology can visualize abstract mathematical concepts contextually and graphically and allow learners to actively construct this knowledge. This study aims to ascertain the efficacy of a…

In this dissertation I will present my work in both the fields of spintronics and physics education research. In the first section, I present a method to account for spin pumping in spin torque ferromagnetic resonance (ST-FMR) measurements. A spin current can be generated via the spin Hall effect (SHE), which is typically transverse to the charge…

The Institute for Education Sciences identifies main idea and summarization instruction as effective practices for improving adolescent students' reading comprehension. Main idea generation is a higher-level comprehension skill that requires students to read the text, connect information across the paragraph or section, determine the most…

This study investigated relations between the distribution of practice problems in textbooks and students' learning of decimal arithmetic. In Study 1, we analyzed the distributions of decimal arithmetic practice problems that appeared in 3 leading math textbook series in the United States. Similar imbalances in the relative frequencies of decimal…

Productive problem solving, concept construction, and sense making occur through the core process of abstraction. Although the capacity for domain-general abstraction is developed at a young age, the role of abstraction in increasingly complex and disciplinary environments, such as those encountered in undergraduate STEM education, is not well…

This design case describes the implementation of the Human-centered Design process, developed by the world leading design firm IDEO and Stanford d. school. The process describes the technology integration onto a teaching credential program course at a university in Central California. It reports the thought process to adopting HCD in the course…

Static electricity is the introductory chapter to electricity in all high school and university Physics textbooks. The interpretations of static electricity phenomena are not obvious, even in higher education. This research was conducted to identify the major difficulties which pre-service primary teachers encounter in explaining static…

We present adaptable activities for models of drug movement in the human body -- pharmacokinetics -- that motivate the learning of ordinary differential equations with an interdisciplinary topic. Specifically, we model aspirin, caffeine, and digoxin. We discuss the pedagogy of guiding students to understand, develop, and analyze models,…

In this article, we describe some of the common misconceptions guests have expressed while visiting a Museum of Natural History and Science, along with ways in which museum educators had reacted to and/or responded to guests' misconceptions. Correcting commonly held misconceptions can be difficult, especially when guests are emotionally invested…

Many authors suggest an explicit reflection on the levels of organisation, based on known difficulties related to understanding biological systems. Yet, there is no scientific consensus on the characteristics of biological levels and the quality of their relationships. This review intends to present the state of the current discussion in order to…

The Three-Square Puzzle shows a remarkable relationship between three angles. What happens when the number of squares increases? This article explores that question and brings in Fibonacci and Lucas sequences.

The calculus concepts of concavity and inflection points are critical for a complete understanding of quantities' behavior, making them important topics of research for those interested in the intersections of STEM disciplines. This study seeks to provide insight into this area by reporting on trends in students' concept projections of these…
