Systematic reviews and meta-analyses are essential for drawing conclusions regarding etiologic associations between exposures or interventions and health outcomes. Observational studies comprise a substantive source of the evidence base. One major threat to their validity is residual confounding, which may occur when component studies adjust for…

Teaching can often seem like an independent endeavor, and seeking out ways to engage in dialogue and exchanges surrounding teaching can be beneficial. Opportunities to observe peers' teaching and discuss teaching practices, challenges, and experiences with peers can lead to an increased sense of community, a fruitful exchange of ideas, and…

Classroom observation is an accountability practice which promotes the evaluation of teachers' capacity to meet standards, improve teaching practices, and enhance student learning outcomes. Prior research has revealed that these practices are not without bias: the reliability of observation can be challenged because of classroom or observer…

Even though many physics teachers take their students on a calculation adventure through circular motion and Newton's universal law of gravity to determine Earth's velocity, most of us leave it at that. We present the final result and say, "Look, Earth is moving around the Sun at about 107,000 km/hr (66,000 mph), yet we can't feel the motion…

We report a Delphi Consensus modification and first validation study of the Autism Diagnostic Observation Schedule -- 2 with deaf children and young people (ADOS-2 Deaf adaptation). Validation included 122 deaf participants (aged 2-18 years), 63 with an Autism Spectrum Disorder (ASD). This was compared to a National Institute for Health and…

Describing the relative severity and change in autism symptoms is crucial for the appropriate characterization of clinical and research populations. The calibrated severity score (CSS) of the Autism Diagnostic Observation Schedule-2 (ADOS-2; Lord et al., 2012) was created to better describe autism symptom severity consistently across different…

In an era where teachers are increasingly being asked to demonstrate evidence of their impact, action research is identified as a practical and critically reflective research approach for enhancing explicit teaching and learning. Using a historical perspective, foundations for reflective practice and action research in educational contexts are…

This research aims to develop the product of the life skill education program (LSEP) which is accurate, credible, and effective. This research used the Plomp model. The model covers the input, process, output, outcome and consists of instrument, scoring guidance, and good or bad criteria. The instruments used in the model are the questionnaire,…

Discovering concepts through observation, exploration, and constructing scientific explanations of phenomena is best practice in science education. Instead of following lab procedures to verify a known answer or solution, involve students in the work of science. Begin by presenting a phenomenon to engage students in scientific inquiry and uncover…

Background: Instructional differentiation within classrooms involves educators' adaptations of instructional elements to meet diverse learners' needs. It is usually regarded as a crucial component of high-quality education that promotes equal and inclusive opportunities for all students. However, defining and operationalising this complex…

This study examined the lived experiences of seven beginning secondary mathematics teachers in an upper Midwestern state who had experienced mentoring and remained in teaching. The study sought to identify the mentoring experiences beginning secondary mathematics teachers perceive as most beneficial to their professional growth. Data were…

There is a dearth of methodological guidance on how to conduct participant observation in private spaces such as family homes. Yet, participant observations can provide deep and valuable data about family processes. This article draws on two ethnographic studies of family life in which researchers conduct in-depth interviews, recruit families, and…

Although the effects of professional development programs on teachers' noticing skills have attracted considerable interest among mathematics education researchers, little is known about the developmental process of prospective teachers' noticing skills within initial teacher education. This paper examines the extent to which prospective teachers'…

Fidelity is defined as doing what is intended. The purpose of measuring fidelity is to assist with supporting implementation. Collecting fidelity data provides an opportunity to problem-solve throughout the process versus waiting for outcome data. More often than not, purchased programs and curriculum materials are missing a research-validated…

The purpose of this paper is to propose a new ontology of reasons for inferentialism. The existing inferentialist approach to mathematics education has a methodological challenge in retrospective analysis and a noncollaborative issue stems from a narrow view of learning. The proposed ontology, built on a radical interpretation of the…
