We investigated the effect of expertise on the wisdom of crowds. Participants completed 60 trials of a numerical estimation task, during which they saw 50-100 asterisks and were asked to estimate how many stars they had just seen. Experiment 1 established that both inner- and outer-crowd wisdom extended to our novel task: Single responses alone…

In making validity arguments, a central consideration is whether the instrument fairly and adequately covers intended content, and this is often evaluated by experts. While common procedures exist for quantitatively assessing this, the effect of loss aversion--a cognitive bias that would predict a tendency to retain items--on these procedures has…

Chemical scientists and engineers are interested in controlling chemical processes to attain specific goals, from synthesizing a desired substance to hindering a particular transformation. Nevertheless, students typically have few opportunities to develop the understandings and practices that are required to effectively engage in chemical control.…

For decades, researchers in our field have explored what it means to possess instructional design expertise. This systematic review provides a current synthesis of research related to cultivating expertise in instructional design coursework. A search on instructional design pedagogy and the development of expertise yielded 34 peer-reviewed…

Experts outperform novices on many cognitive and perceptual tasks. Extensive training has tuned experts to the most relevant information in their specific domain, allowing them to make decisions quickly and accurately. We compared a group of fingerprint examiners to a group of novices on their ability to search for information in fingerprints…

In this paper, the authors describe the initial stage of developing a framework designed to support out-of-field, less experienced or isolated mathematics and science teachers to make decisions about the use of resources in their teaching. The process highlighted the complexity and extent of the knowledge on which expert teachers draw in making…

In 2014, Macnamara, Hambrick, and Oswald published a meta-analysis of studies questioning the strength of the association between deliberate practice and performance. In this brief report, the correlation reported by Macnamara et al. (2014) is placed in the context of other well-known associations. Additionally, a re-analysis of the studies…

Scoring mathematics exam papers accurately is vital for fostering students' engagement and interest in the subject. Incorrect scoring practices can erode motivation and lead to the development of false self-confidence. Therefore, the implementation of appropriate scoring methods is essential for the success of mathematics education. This study…

This study aims to explore Web 3.0 technology, a transformative internet evolution that has just begun impacting our lives and is expected to play a pivotal role in shaping the future, alongside the Metaverse and its potential applications in education. Through insights gathered from five field experts via semi-structured interviews, this study…

Structural questions about the undergraduate political science major have spurred debates in the field for more than thirty years. Today, resurgent growth of unusually sharp threats to American democracy fuel familiar curricular questions with new urgency. However, the combined effects of inertia, bureaucratic hurdles, and resource constraints…

Over the last two decades, early childhood education (ECE) has come to the top of the political agenda in New Zealand and internationally. The interest of governments and policy-makers in ECE has been driven by the thinking that an 'investment' in ECE is a key for a country's future social and economic development (OECD 2007, "Policy Brief:…

This collaborative autoethnography explores the shifting power dynamics in a youth-adult research partnership within a participatory design research project focused on a youth-led online writing community. The authors, a former high school teacher/now doctoral student researcher and former high school students/current co-researchers, analyze their…

In the Chinese vocational education context, expert feedback plays an important role in many teacher professional development programs, such as mentoring, lesson observation, teaching evaluation, and expert-teacher workshops. Previous research examined the general setting and effectiveness of these programs and did not go into depth about the…

The increasing focus on STEM education has prompted the introduction of teacher training programs at the state level. However, such programs tend to be poorly adapted to specific contexts. Therefore, conducting diagnostic assessments for ascertain the existing conceptions and competencies of in-service teachers to facilitate the implementation of…

Reform-oriented instruction is advocated in secondary science, encouraging students to engage with the experimental and epistemic practices of science. It is challenging for teachers though, especially for out-of-field teachers. This study focuses on biology and chemistry teachers who are called to teach middle-school physics. These teachers face…
