Pedigree problems are typical tasks in school genetics classes. However, they are perceived as difficult and often are not successfully completed. Therefore, the purpose of this study is to determine relevant factors that might have an impact on success in pedigree analysis. Based on previous research, we investigate the influence of the…

Ongoing evaluation of student progress is a key practice within tiered systems of supports. This study evaluated whether selecting an intervention influenced the number of observations participants requested before determining whether an intervention was working or a change was needed. It was hypothesized that participants who selected the…

Problem-solving frameworks have the potential to promote objective data-based decisions that increase the likelihood students are matched to appropriate evidence-based interventions. Unfortunately, cognitive biases, heuristics, and fallacies can lead to erroneous conclusions within problem-solving frameworks. Some of these effects have been…

During the last two years, the COVID-19 pandemic had a secondary effect of increased media content loaded with mathematical, often probabilistic information (and misinformation). Our exploratory study investigates the probabilistic intuitions, misconceptions, biases, and fallacies in conditional probability reasoning of mathematics teacher…

The purpose of this study was to 1) help novice students scaffold problem-solving and engage safely in the deliberate practice of diagnostic reasoning and medical decision-making in real time; 2) assess how accurately students gather and apply data in medical reasoning and treatment during high-fidelity patient simulations (HFPSs); 3) identify…

We examined the type of errors on multiplication and division computation problems of 326 rising fifth graders enrolled in four elementary schools in Northern Portugal. We further examined whether there was a difference in the number of errors across age and whether there was an association between students' performance on number knowledge and…

In early care and education, a multitiered system of support (MTSS) framework is a way to provide high-quality teaching and responsive caregiving through the delivery of differentiated support for all young children. In an early childhood MTSS framework, the needs of every child, regardless of ability, eligibility status, cultural and linguistic…

Metacognition is central to children's cognitive development. However, there is conflicting evidence about children's ability to accurately monitor their performance and subsequently control their behavior. This is of particular interest for mathematics topics on which children exhibit persistent misconceptions--that is, when children's knowledge…

With the expansion of computer science (CS) education, CS teachers in K-12 schools should be cognizant of student misconceptions and be prepared to help students establish accurate understanding of computer science and programming. This exploratory design-based research (DBR) study implemented a data-driven approach to identify secondary school…

An experiment published in this "Journal" has been revisited and it is found that the curve pattern of the anodic polarization curve for iron repeats itself successively when the potential scan is repeated. It is surprising that this observation has not been reported previously in the literature because it immediately brings into…

Comparing multiple solutions to a single problem is an important mode for developing flexible mathematical thinking, yet instructionally leading this activity is challenging (Stein, Engle, Smith, & Hughes, 2008). We test 1 decision teachers must make after having students solve a problem: whether to only verbally discuss students' solutions or…

This paper makes a case that decision making (DM) is not social problem solving (SPS) and DM is subordinate and subsumed within SPS. Both terms are defined and distinguished. Confusion between SPS and DM is widespread and has occurred for at least four decades. DM, not SPS, has been established as one of the seven National Health Education…

Analyzes three widely-held conceptions of critical thinking: as one or more skills, as mental processes, and as sets of procedures. Considers each a misconception and offers alternative proposals for teaching critical thinking. (CMK)

Social studies educators advocate discussion as an influential instructional method to encourage students to apply knowledge and develop higher-order thinking and understanding. The classroom reality, however, is that teachers only use the discussion method sparingly. Instead, teachers predominantly use a quasi-discussion form called recitation to…

The errors and strategies made by students who consistently use the incorrect-addition strategy on "hard" ratio tasks were investigated. The characteristics of these "adders," such as awareness of noninteger multiples, the use of fractions and decimals, awareness of both within and between ratios, and distinguishing nonratio…
