It argues that the probable explanation relates to masking: Only one outcome measure was administered by…

Memory plays a key role in learning, and it is therefore important that teachers understand its workings in order to make decisions that benefit learning. However, previous research has shown that memory is an area which is subject to misconceptions. This study used an online survey with a five-item Likert scale to determine teachers' responses to…

The purpose of this study was to explore the effect of Content Representations (CoRes) construction, and reflective peer discussions on pre-service physics teachers' pedagogical content knowledge (PCK).

Engaging non-conventional gatekeepers such as the police presents both promises and perils. Although studies have relied on police data for researching suicide and other sensitive topics in Africa, there is a paucity of literature that explores or reflects on police gatekeeping and its research implications. This paper presents authors'…

Each of us has an implicit leadership theory, a mental model we are largely unaware of, that represents the skills, traits, and qualities that define effective leaders. Curiously, the peer reviewed literature has reported almost exclusively on the ideal attributes of leaders, overlooking the axiomatic and taken-for-granted views people have about…

This article analyses recent World Bank interventions aimed at improving higher education and local research capacity in low-income countries. Our empirical entry point is a critical analysis of the Development and Innovation Grant (DIG) scheme the Bank rolled out in Cambodia (2010-2015), a virtual carbon copy export of its Academic Initiative…

Broad misconceptions about global climate change (GCC) could hinder efforts to address this large-scale problem, and curricular materials can play a substantial role in what students learn about GCC. This study examines how U.S. high school textbooks and supplemental curricular materials published between 2007 and 2012 portray the causes,…

Educational practice does not, for the most part, rely on research findings. Instead, there's a preference for relying on our intuitions about what's best for learning. But relying on intuition may be a bad idea for teachers and learners alike. This accessible guide helps teachers to integrate effective, research-backed strategies for learning…

The purpose of this qualitative study was to examine the perceptions of parents and teachers of elementary school students regarding homework.

In recent decades, open, online learning environments have become progressively more popular and well-funded. An integral aspect of this open learning movement is the transition of a substantial amount of control of the learning process from designers and instructors to the users engaging with the environment. With heavy investments coming from…

This research examines viewpoints held by pre-service science teachers on key concepts of the Nature of Science (NoS) in the Saudi context. Much research in this context emphasises quantitative methods, so this research utilises methodological triangulation to validate the data. Quantitative data was first obtained from 35 pre-service teachers…

Problem-solving is one of the 21st-century skills. However, students still have difficulty solving sequences and series word problems. The purpose of this research is to analyze students' errors in solving sequences and series word problems based on problem-solving steps of Polya. The research method is descriptive qualitative. The research…

This study is empirical research about alternative ideas on the concept of force for five different age groups, primary school students (11), middle school students (15), high school students (17), students of the Department of Primary Education (21), and active teachers in primary education (27-50). We used the same questionnaire for all groups,…
