Motion planning is a core problem in robotics concerned with finding feasible paths for a given robot. Motion planning algorithms perform a search in the high-dimensional continuous space of robot configurations and exemplify many of the core algorithmic concepts of search algorithms and associated data structures. Motion planning algorithms can…

Modern robots, like today's smartphones, are complex devices with intricate software systems. Introductory robot programming courses must evolve to reflect this reality, by teaching students to make use of the sophisticated tools their robots provide rather than reimplementing basic algorithms. This paper focuses on teaching with Tekkotsu, an…

Computer science proficiency continues to grow in importance, while the number of students entering computer science-related fields declines. Many rich programming environments have been created to motivate student interest and expertise in computer science. In the current study, we investigated whether a recently created environment, Robot…

We propose an expanded definition of Threshold Concepts (TCs) that requires the successful acquisition and internalisation not only of knowledge, but also its practical elaboration in the domains of applied strategies and mental models. This richer definition allows us to clarify the relationship between TCs and Fundamental Ideas, and to account…

The loss of biodiversity is one of the most urgent global environmental problems of our time. Public education and awareness building is key to successful biodiversity protection. Knowledgeable and skilled student teachers are a key component for the successful implementation of biodiversity education in schools. Yet, little empirical evidence…

This study aimed to examine the written arguments developed by college freshman students using the Science Writing Heuristic approach in inquiry-based general chemistry laboratory classrooms and its relationships with students' achievement in chemistry courses. Fourteen freshman students participated in the first year of the study while 19…

Currently, there are policy debates regarding the efficacy and legality of single sex formal and informal education programs. This issue is particularly poignant in science education due to the historical marginalization of women in these fields. This marginalization has resulted in women being positioned as a stigmatized group within many…

This study is part of a 5-year National Science Foundation-funded project, Transforming Elementary Science Learning Through LEGO™ Engineering Design. In this study, we report on the successes and challenges of implementing an engineering design-based and LEGO™-oriented unit in an urban classroom setting and we focus on the impact of the unit on…

This study was part of a multi-year project on the development of elementary students' modeling approaches to understanding the life sciences. Twenty-three first grade students conducted a series of coordinated observations and investigations on decomposition, a topic that is rarely addressed in the early grades. The instruction included…

Vygotsky (1986) draws attention to the interrelationship between thought and language and other aspects of mind. Although not widely acknowledged, Vygotsky (1999) also drew attention to the search for the relations between cognition and emotions. This paper discusses the findings of a study which examined imaginary scientific situations within the…

In this article, we present the results from a mixed-methods research study aimed to document indoor and outdoor fifth grade science experiences in one school in the USA in the context of accountability and standardized testing. We used quantitative measures to explore students' science knowledge, environmental attitudes, and outdoor comfort…

A concern commonly raised in literature and in media relates to the declining proportions of students who enter and remain in the "science pipeline", and whether many countries, including Australia and New Zealand, have enough budding scientists to fill research and industry positions in the coming years. In addition, there is concern…

In contrast to Thomas Kuhn, the work of Ludwik Fleck, a Polish-born physician, microbiologist, and epistemologist, is conspicuously absent from the science education literature. His originally obscure monograph first published in German in 1935, "Genesis and Development of a Scientific Fact," anticipates a number of views explicated by…

Science communication competence (SCC) is an important educational goal in the school science curricula of several countries. However, there is a lack of research about the structure and the assessment of SCC. This paper specifies the theoretical framework of SCC by a competence model. We developed a qualitative assessment method for SCC that is…

The biological community is currently undertaking one its greatest scientific endeavours, that of constructing the Tree of Life, a phylogeny intended to be an evidenced-based, predictive road map of evolutionary relationships among Earth's biota. Unfortunately, we know very little about how such diagrams are understood, interpreted, or used…
