This study aims to develop and evaluate an augmented reality microscope, "MicrosAR", for a middle school Science course, which was aimed for use both in and out of school, and to understand the users' perceptions about it. The study adopted design-based research to iteratively develop and evaluate the MicrosAR. Learning activities and…

The study sought to establish the contribution of infrastructural availability to school growth and sustainable improvement of academic performance in selected secondary schools in Tororo District. The study employed a qualitative approach, and data were collected from school administrators, the management team and teachers using open-ended…

Background: Early childhood leadership leads to positive outcomes for young children, including social competence. Objective: The purpose of the present study was to examine the leadership behavior exhibited by three preschool aged children and to determine if teacher prompting could increase the frequency of leadership behaviors exhibited by…

Since 2018, a language-learning scheme has been specifically designed for first-year students at the University of Lorraine. Its intended objective is to make them aware of the many possibilities, strategies and methodologies to learn languages, other than simply attending classes. Developing learner autonomy and inciting the students to use all…

Background/purpose: The current trend of training Chemistry teachers focuses on innovating pedagogical methods and developing students' holistic competencies, particularly their chemistry experimentation competencies (CEC). The CDIO (Conceive - Design - Implement - Operate) framework effectively combines theoretical knowledge with practice and…

Effective elementary science education is fundamentally dependent on teachers' science content knowledge and self-efficacy in teaching science, areas that have been central to science education reform initiatives. This study examines the development and implementation of a physical science content course curriculum incorporating both hands-on…

Twice exceptional (2e) students are students who are both gifted and have a disability. At the intersection of exceptionality and race, twice exceptional students from racially minoritized communities may experience behavioral difficulties in schools. In this article, we provide information for educators as well as school and district…

Enzymatic activity is at the core of biological reactions. Understanding them and the chemical and environmental factors that affect reaction rates is critical for biology students. The laboratory experiment proposed here investigated these concepts, while requiring students to document, graph data, analyse results using statistics, and…

Apart from the evident tragedy that the COVID-19 outbreak has meant regarding both personal and economic costs, the normal functioning of the academic year has been drastically altered at all educational levels. Regarding Spain, the state of alert implemented by the government from mid-March to June has affected traditional face-to-face sessions…

Due to the unique and advantageous physiochemical properties of nanoparticles, they have been increasingly incorporated into consumer products and emerging technologies. The manufacture, wear and tear of use, and disposal of these nano-enabled products will likely result in the release of nanoparticles into the environment. Unfortunately,…

In the course of PISA and TIMSS a lot of out-of-school lab days have been established; as non-formal extracurricular learning environments they shall provide an efficient addition to formal learning at school. The "ELKE" project is a non-formal extracurricular learning lab that aims at linking curricular content and competence-centred…

This research presents the investigation of physics students' and physics faculty members' professional development and a design methodology via which we could best support them in their professional development. In particular, the first part of this dissertation will focus on undergraduate upper-division physics students' conceptual learning and…

An iridium(III)-mediated C-H functionalization sequence involving a concerted cyclometalation-deprotonation/migratory insertion pathway is reported for the undergraduate chemistry laboratory. The air- and water-stable iridacycle intermediates are readily isolated and characterized by NMR spectroscopy. Both steps of the experiment are performed at…

A high performance liquid chromatography (HPLC) experiment for the upper level analytical chemistry laboratory is described. The students consider the effect of mobile-phase composition and pH on the retention times of ionizable compounds in order to determine the acid dissociation constant, K[subscript a], of a phenolic acid. Results are analyzed…

This is a description of the conceptual foundations used for designing a novel learning environment for mechanics implemented as an "Industrial Educational Laboratory"--called Fisica in Moto (FiM)--at the Ducati Foundation in Bologna. In this paper, we will describe the motivation for and design of the conceptual approach to mechanics…
