Mathematics for teaching and deep subject knowledge: voices of Mathematics Enhancement Course students in England

This article reports an investigation into how students of a mathematics course for prospective secondary mathematics teachers in England talk about the notion of ‘understanding mathematics in depth’, which was an explicit goal of the course. We interviewed eighteen students of the course. Through our social practice frame and in the light of a review of the literature on mathematical knowledge for teaching, we describe three themes that weave through the students’ talk: reasoning, connectedness and being mathematical. We argue that these themes illuminate privileged messages in the course, as well as the boundary and relationship between mathematical and pedagogic content knowledge in secondary mathematics teacher education practice.     

The Effectiveness of an Augmented Reality Head-Mounted Display in Learning Skull Anatomy at a Community College

Despite an increase in the use of technology in undergraduate anatomy education, and the rising popularity of online anatomy courses at community colleges in the United States, there have been no reports on the efficacy of augmented reality on anatomy education in this population. The purpose of this study was to test the hypothesis that augmented reality is an effective and engaging tool for learning anatomy in community college students. Participants recruited from Cuyahoga Community College (Cleveland, OH) studied skull anatomy using either traditional tools (i.e., textbook and plastic skull model) or an augmented reality head-mounted display with an interactive virtual skull application. Comparison of knowledge before and following the study period revealed that augmented reality was an effective tool for learning skull anatomy: pre-quiz = 32.7% (± 25.2); mean (± SD), post-quiz = 61.8% (± 19.5); n = 15; t₍₂₈₎ = 3.53; P = 0.001. The traditional tools were equally effective: pre-quiz = 44.9 % (± 18.6), post-quiz = 67.9 % (± 17.3); n = 17; t₍₃₂₎ = 3.73; P = 0.0007. Students rated the augmented reality device as 9.6 (± 1.0); mean (± SD) when asked if it fit the statement “fun to use” on a semantic differential scale from 1 (poor) to 10 (excellent). In conclusion, this study found that augmented reality is an effective and engaging tool for the instruction of skull anatomy at a community college.     

Is remote near-peer anatomy teaching an effective teaching strategy? Lessons learned from the transition to online learning during the Covid-19 pandemic

In response to the Covid-19 pandemic, medical educators have transformed pre-clerkship anatomy curricula into online formats. The purpose of this study was to evaluate the effectiveness and student perceptions of an online near-peer anatomy curriculum. The classes of 2022 and 2023 completed identical foundational anatomy curricula in-person, whereas the class of 2024 completed an adapted curriculum for remote online learning. Quantitative and qualitative responses were used to compare attitudes between instructional methods. Assessment scores and evaluation survey responses were collected from the classes of 2022 (n = 185), 2023 (n = 184), and 2024 (n = 183). Mean assessment scores (±SD) for the classes of 2022, 2023, and 2024 were 93.64% (±5.86), 93.75% (±4.09), and 92.04% (±4.83), respectively. Post hoc group comparisons showed the class of 2024 scored significantly lower than the two previous classes [2022: (H(1) = 18.58, P < 0.001), 2023: (H(1) = 18.65, P < 0.001)]. Mean survey results concerning curriculum quality were 4.06/5.00 for the class of 2023 and 3.57/5.0 for the class of 2024 (t(365) = 2.67, P = 0.008). Considering a small effect size (η² = 0.034), there was no meaningful difference in student assessment scores. A potential drawback of online near-peer anatomy teaching remains in student perceptions of course quality; qualitative feedback suggested technological limitations and perceptions of online course instructors were partly responsible for lower student satisfaction. Following the Covid-19 pandemic, medical educators should incorporate the lessons learned from this unique educational inflection point to improve curricula moving forward.     

Name writing but not environmental print recognition is related to letter-sound knowledge and phonological awareness in pre-readers

This paper reports a study exploring the associations between measures of two levels of phonological representation: recognition (epi-linguistic) and production (meta-linguistic) tasks, and very early reading and writing skills. Thirty-eight pre-reading Ottawa-area children, aged 4–5 years, named environmental print (EP), wrote their own name, identified correct names and EP words amongst foils and detected foil letters within EP and names. Results showed that phonological awareness and letter-sound knowledge were not related to EP recognition. Name writing accuracy and name identification were related to both levels of phonological awareness. Furthermore, name writing showed a unique association with phonological awareness even after letter-sound knowledge was controlled statistically. Pre-readers may first use meta-linguistic phonological awareness in their name writing and identification prior to learning to read.     

Sex differences in the etiology of aggressive and nonaggressive antisocial behavior: results from two twin studies

Recent theory and results from twin and adoption studies of children and adolescents suggest greater genetic influence on aggressive as compared to nonaggressive antisocial behavior. In addition, quantitative or qualitative differences in the etiology of these behaviors in males and females have been indicated in the literature. The Child Behavior Checklist was completed by the parents of 1022 Swedish twin pairs aged 7-9 years and of 501 British twin pairs aged 8-16 years. Genetic factors influenced aggressive antisocial behavior to a far greater extent than nonaggressive antisocial behavior, which was also significantly influenced by the shared environment. There was a significant sex difference in the etiology of nonaggressive antisocial behavior. Bivariate analyses supported the conclusion that the etiologies of aggressive and nonaggressive antisocial behavior differ for males and females.     

Improving the Measurement of Cognitive Skills Through Automated Conversations

Open-ended, short-answer questions, referred to as constructed responses (CR), allow students to express knowledge and skills through their own words. While CRs can reduce the likelihood of guessing correct answers, they also enable students to provide errant responses due to a lack of knowledge or a misunderstanding of the question. Conversation-based assessments (CBAs) require constructing responses to open-ended prompts (similar to CRs), but also leverage natural-language processing to provide adaptive follow-up prompts that target particular information. This work describes an investigation into potential benefits of CBAs as they are compared to a CR approach. Results from 632 middle schoolers indicate that, when compared to CRs, the CBA items allowed 41% of students to provide a more complete response and improve their score.     

Sustaining education for sustainability in turbulent times

A study of two schools in northern Australia demonstrated the impact on Education for Sustainability (EfS) initiatives of a disruptive policy environment set in motion by neoliberal reforms focused on standards, accountability, and international competitiveness. In one of the schools, a culture characterized by trust and an emphasis on cultivating teacher and student strengths and interests contributed to the resilience of these initiatives in the face of outside pressures. In the other, administrators preoccupied with the need to implement state mandates with fidelity failed to nurture and develop a collection of remarkable EfS projects and activities.     

Fostering the Development of Reading Skill through Supplemental Instruction: Results for Hispanic and Non-Hispanic Students

This paper reports the effects of a two-year supplemental reading program for kindergarten through third grade students that focused on the development of decoding skills and reading fluency. Two hundred ninety-nine students were identified for participation and were randomly assigned to the supplemental instruction or to a no-treatment control group. Participants' reading ability was assessed in the fall, before the first year of the intervention, and again in the spring of years 1, 2, 3, and 4. At the end of the two-year intervention, students who received the supplemental instruction performed significantly better than their matched controls on measures of entry level reading skills (i.e., letter-word identification and word attack), oral reading fluency, vocabulary, and comprehension. The benefits of the instruction were still clear two years after instruction had ended with students in the supplemental-instruction condition still showing significantly greater growth on the measure of oral reading fluency. Hispanic students benefited from the supplemental reading instruction in English as much as or more than non-Hispanic students. Results support the value of supplemental instruction focused on the development of word recognition skills for helping students at risk for reading failure.
