This paper studies how the concept of "Diversity, Equity & Inclusivity" (DE&I) has been instrumentalised "in lieu" of effective policies to tackle racism and racial inequity in Higher Education and in particular in Library and Information Science (LIS). The author takes stock of the research output devoted to this topic…

The purpose of this study is to describe the conditions under which diffracting noticing becomes both a process and product in dynamic relations to re-imagine preservice science teachers' becoming as ethical mattering, a concept rooted in a relational ontology of change and emergence. Drawing on theories of posthumanism, this study theorized…

Practical work is widely seen as an integral part of school science. Research and teacher guidance have tended to consider practical work in science, rather than in individual science subjects or topics. This study used a questionnaire of selected- and open-response items to probe the views and reasoning of a sample of 43 pre-service teachers in…

The ways in which children and adolescents become interested in science have been well studied. However, little is known from a lifespan perspective about how this process continues from childhood through adulthood. This cross-national study builds an understanding of doctoral students in the sciences in the Chile and the United States and how…

This study determined how chemistry instruction using technology affected student achievement and retention. To achieve the goal of the study, Solomon's four-group quasi-experimental research design was used. The one-way analysis of variance (ANOVA) and independent sample t-test were used to statistically examine the data. A one-way ANOVA analysis…

The three articles in this dissertation explore how curriculum, instruction, and assessments should align with the vision for science learning outlined in the Framework for K-12 Science Education. Together, the papers demonstrate how curriculum, instruction, and assessment, when mutually supportive of each other, can foster a learning environment…

Scholars over the past few years have drawn attention to the enormous potential role historical stories can play in promoting student understanding of issues associated with the nature of science (NOS). Such stories, often referred to as "historical narratives," are thought to do so by providing a rich historical context within which…

The use of red cabbage ("Brassica oleracea var. capitata F. rubra") extract as a pH indicator is a versatile and popular demonstration that is employed by educators in many schools and universities. Previous variations of this demonstration have used red cabbage extracts to prepare paper that changes color when solutions of acid or base…

The basics of organic chemistry nomenclature were introduced in a laboratory organized in a nonformal environment such as a science festival. The laboratory, divided into three distinct but interconnected activities, was aimed not only at secondary school students but also at lay people. The intent was to explain the importance of associating a…

High quality science teaching builds pupils' curiosity and critical thinking, helping them to develop a coherent understanding of the world around them. Primary science teaching plays a crucial role in shaping pupils' attitudes toward the subject, nurturing participation that can support future pathways into science, technology, engineering, and…

Forces and motion are at the heart of physics and children start learning from the moment they are able to interact with the world. Children as young as one year show surprise when a ball does not behave as expected. This is a tremendous bonus to learning physics, but it has hidden dangers: they only learn how things move on the Earth, where we…

The Wilson cloud chamber is an apparatus used for detecting and observing the trails of alpha/beta rays or even cosmic rays in saturated gas conditions. The principle of this device is based upon the powerful ionization of the aforementioned rays within the medium. This article will provide instruction for creating a classic version of the cloud…

There are several 'cool' mechanisms that result in materials luminescing or emitting light. Artificial luminescence has often been created by mimicking nature and there are many examples of applications in society. It is very likely that most of your students will have observed luminescence in one form or another, such as glow sticks,…

It is well known that the needle of a compass in a magnetic field deflects, and that a compass near a conductive wire carrying a stable electric current deflects its needle. The only explanation of this observation is that the current-carrying wire creates a magnetic field around it. The strength of the magnetic field at any point near the wire…

If a ball rolls in a circular path on a horizontal surface at constant speed then its horizontal rotation axis changes direction with time. A simple experiment is presented showing that the torque applied to the ball is equal to the rate of change of its angular momentum, even though the magnitudes of its angular velocity and angular momentum…
