We used an adapted alternating treatment single-case design to compare the effect of affirmative feedback to affirmative plus suggestive feedback on educators' use of naturalistic instruction. Three early childhood special educators and a focus child within their preschool classrooms participated. Visual analysis of our data suggest that…

When fitting unidimensional item response theory (IRT) models, the population distribution of the latent trait ([theta]) is often assumed to be normally distributed. However, some psychological theories would suggest a nonnormal [theta]. For example, some clinical traits (e.g., alcoholism, depression) are believed to follow a positively skewed…

Longitudinal data analysis has been widely employed to examine between-individual differences in within-individual changes. One challenge of such analyses is that the rate-of-change is only available indirectly when change patterns are nonlinear with respect to time. Latent change score models (LCSMs), which can be employed to investigate the…

Middle level school teachers commonly measure and monitor students' academic performance, but such is not the case for students' classroom behavior. This is unfortunate, given the rise in students' classroom behavior problems in middle school, especially for students who experience emotional or behavioral disorders. The Classroom Performance…

Teachers' beliefs about education influence practice and vice versa. Teacher educators should be particularly attuned to the association between educational beliefs and practice. Teachers' beliefs about education have been widely studied, but investigating how a team of teacher educators put a shared vision on blended learning into practice is…

Impact evaluation and measurement are highly complex and can pose challenges for both social impact providers and funders. Measuring the impact of social interventions requires the continuous exploration and improvement of evaluation approaches and tools. This article explores the available evidence on meta-evaluation--the "evaluation of…

Many countries and regions have reached a consensus to promote science, technology, engineering, and mathematics (STEM) education in the past decade. A body of studies have demonstrated that the design and organization of interdisciplinary teaching activities are important for the effective implementation of STEM education. So far, however, little…

Teacher retention rates continue to plummet at schools across the nation. A principal at Sunnyside Elementary watches firsthand as the revolving door of teachers increases significantly in her brief 3 years of leadership at this school. Once well-known and highly regarded at an award-winning school in the northeast, the principal struggles to…

Formal evaluation of policies, programmes and people has become ubiquitous in contemporary western contexts. This is the case for equity and widening participation (WP) agendas in higher education, for which evaluation is often required to measure 'what works'. Although evaluation has a 'fundamentally social, political, and value-oriented…

Several properties of Earth's magnetic field (field vectors, time dependence) are measured in various locations using a smartphone/tablet magnetic sensor. To enable a proper use of the magnetic sensor as a classroom tool, the exact location of the sensor in the device and its resolution must be identified in a first step. Then, students may…

The planet Mercury transited the face of the Sun in a rare spectacle on 11 November 2019. It was an awe-inspiring moment for 300 students from Kwabenya Community High School and Ghana Atomic Energy Commission Basic School in Ghana to see this wonder of the cosmos. Celestron Power Seeker 60 mm diameter telescopes were used to project the Sun's…

Visual literacy equips learners with the dispositions to critically create, analyse, use, and share visual information. As one component of a discerning, ethical citizenry, visual literacy has become more essential in a rapidly evolving information ecosystem. Against this backdrop, the current Association of College and Research Libraries Visual…

The educational paradigm is constantly evolving; this is largely due to continuous emerging educational tools and technologies. This development has altered the traditional ways of teaching and learning. Present global trends have further increased or forced the adoption of technology in all its ramifications, resulting in a reliance that could…

This action research aims to develop the scientific explanation of grade 10 students using sociobiological case-based learning on the topic "immune system". The target group consisted of 2 1students who are studying in biology course. The research instruments were: plan of instrument using sociobiological case-based learning, scientific…

The early years of teaching are important for science teachers, but little is known about how science teachers develop professionally in their early years. This mixed methods study took a longitudinal view of the early years of teaching. Following 95 secondary science teachers over a 5-year period, this study examined the beliefs, pedagogical…
