‘Powerful knowledge’ curriculum theories and the case of physics

A stream of debate (including a previous special issue of this journal (25(1) 2014)) has made claims not just for ‘bringing knowledge back in’ as the framing underpinning of the school curriculum, but that subjects associated with disciplinary and disciplined knowledge forms have a particular power and that these characteristics are important to preserve in curriculum frameworks. This paper draws on a major Australian research project studying school and university physics in the context of these arguments to revisit the issue of the ‘discipline’ of physics and the curriculum logics for physics. Given that disciplines are social in origin and changing and expanding over time, can school curriculum be logically derived from the discipline to which they relate? Are questions about student engagement only questions about pedagogy and not curriculum? Does a focus on disciplinary knowledge mean that the role of school in forming identities and values is avoidable as a significant feature of what the curriculum does? The findings from the project are used both to illustrate and test these questions, and to challenge some over-simple assumptions about the verticality of this form of knowledge for education purposes.     

Dramatizing the Authentic Research of a Local Scientist to Urban Elementary Students Through Professional Theater

This article focuses on the impact of a professional play that we developed in order to introduce elementary learners of an urban school to the research of a scientist working at a local university. The play was written in a way that might increase student understandings of the nature of science, scientific inquiry, the identity of scientists, and the work that scientists do. We collected pre-and post-play questionnaire responses and drawings of scientists from third and fourth grade students who attended the play. We also interviewed five of the ten teachers whose students attended the play. Findings indicated that most of these teachers felt strongly that their students had learned about scientific inquiry, the identity of scientists, and the work that scientists do as a result of attending the play. However, less than half of the student questionnaires and drawings of scientists indicated such growth as a result of the play. That being said, numerous students were able to tell us what they learned from the play and many questionnaire responses and drawings indicated such learning. Implications for partnerships between schools and university faculty from various disciplines in order to develop potentially impactful plays that portray authentic scientific research are discussed.     

“Why do dogs pant?”: Characteristics of parental explanations about science predict children's knowledge

Using a new method for examining parental explanations in a laboratory setting, the prompted explanation task, this study examines how characteristics of parental explanations about biology relate to children's knowledge. Parents (N = 148; M_age = 38; 84% female, 16% male; 67% having completed college) of children ages 7–10 (M_age = 8.92; 47% female, 53% male; 58% White, 9.5% Black, 9.5% Asian) provided answers to eight how and why questions about biology. Parents used a number of different approaches to address the questions, including providing more mechanistic responses to how questions and more teleological responses to why questions. The characteristics of parental explanations—most notably, how frequently parents provided correct responses—predicted children's performance on measures of verbal intelligence and biological knowledge. Additional exploratory analyses and implications for children's learning are discussed.     

YouTube-based course orientation videos delivered prior to matriculation fail to alleviate medical student anxiety about anatomy

Gross anatomy is a source of anxiety for matriculating medical students due to the large volume of information presented in a truncated timeline, and because it may be their first exposure to human cadavers. This study aimed to assess if video-based resources would affect matriculating medical students' anatomy state anxiety levels. Videos were designed to be short, YouTube-based units that served to provide orientation information about the anatomy course, dissection facilities, and available study resources to dispel anxiety around beginning their anatomy studies. To evaluate the impact of the videos, students in two consecutive matriculating years (2018 and 2019) completed the validated State-Trait Anxiety Inventory and a demographic questionnaire. The 2019 cohort (n = 118) served as the experimental group with access to the videos; while the 2018 cohort (n = 120) without video access served as a historical control. Analyses revealed that the groups were equivalent in terms of trait anxiety (P = 0.854) and anatomy state anxiety even when student video exposure was controlled (P = 0.495). Anatomy state anxiety was only significantly lower in students with prior formal anatomy exposure (P = 0.006). Further inquiry into students' prior anatomy experience identified that individuals with post-secondary dissection experience were significantly less anxious than those without formal anatomical experience (P = 0.023). These results may serve as a cautionary tale to educators; while preference for video-based instructional materials is prevalent in the literature, videos delivered on public social media platforms fail to prepare students for the psychological impact of studying human anatomy.     

Educating the adult brain: How the neuroscience of learning can inform educational policy

The acquisition of new skills in adulthood can positively affect an individual’s quality of life, including their earning potential. In some cases, such as the learning of literacy in developing countries, it can provide an avenue to escape from poverty. In developed countries, job retraining in adulthood contributes to the flexibility of labour markets. For all adults, learning opportunities increase participation in society and family life. However, the popular view is that adults are less able to learn for an intrinsic reason: their brains are less plastic than in childhood. This article reviews what is currently known from neuroscientific research about how brain plasticity changes with age, with a particular focus on the ability to acquire new skills in adulthood. Anchoring their review in the examples of the adult acquisition of literacy and new motor skills, the authors address five specific questions: (1) Are sensitive periods in brain development relevant to learning complex educational skills like literacy? (2) Can adults become proficient in a new skill? (3) Can everyone learn equally effectively in adulthood? (4) What is the role of the learning environment? (5) Does adult education cost too much? They identify areas where further research is needed and conclude with a summary of principles for enhancing adult learning now established on a neuroscience foundation.     

Evidence for a simplicity principle: teaching common complex grapheme‐to‐phonemes improves reading and motivation in at‐risk readers

This study examines the effects of teaching common complex grapheme‐to‐phoneme correspondences (GPCs) on reading and reading motivation for at‐risk readers using a randomised control trial design with taught intervention and control conditions. One reading programme taught children complex GPCs ordered by their frequency of occurrence in children's texts (a ‘simplicity principle’). The other reading programme taught children word usage. Thirty‐eight students participated in the 9‐week programme of 30 supplemental small group sessions. Participants in the complex GPC group performed significantly better at post‐tests with generally large value‐added effect sizes (Cohen's d) at both by‐participant and by‐item for spelling, d = 1.85, d = 1.16; word recognition with words containing taught GPCs, d = 0.96, d = 0.95; word recognition, d = 0.79, d = 0.61, and reading motivation, d = 0.34, d = 0.56. These findings suggest that the simplicity principle aids in structuring maximally effective supplemental phonic interventions.     

What knowledge and conceptions do Irish primary schoolteachers hold on attention deficit hyperactivity disorder?

Attention deficit hyperactivity disorder (ADHD) diagnosis rates have increased significantly in recent times. A teacher's role is crucial in determining if a child will be referred for an ADHD assessment. Teachers' opinions and observations are also required for and play a huge role in the actual assessment process. For this reason, their knowledge of ADHD is also an important part of this process. This research has measured, on a small scale, Irish primary schoolteacher's knowledge and conceptions about ADHD using the Knowledge of Attention Deficit Disorders Scale (KADDS) questionnaire. Ninety teachers participated in the research from 11 primary schools in County Clare. A quantitative method was utilised enabling the research to be comparable with other pieces of research using the same questionnaire. Data in relation to the teachers' professional background were also gathered in order to analyse significant differences based on a variety of factors. The results were analysed as prescribed in KADDS test manual using the statistical software package SPSS. This research shows that Irish primary schoolteachers are more knowledgeable in regards to ADHD symptoms and diagnosis than they are in the areas of associated features or treatments. It also shows that knowledge levels of Irish primary schoolteachers are higher than teachers in earlier research using the same questionnaire.     

Building Conceptual Understanding of Multiplicative Reasoning Content in Third Graders Struggling to Learn Mathematics: A Feasibility Study

This formative study of a multiplicative reasoning (MR) intervention explored the intervention's potential for improving the ability of third-grade struggling students’ ability to reason with multiplicative concepts and procedures. The feasibility of the study was examined in a school setting before a randomized control trial was conducted. Students who scored between the 10th and 35th percentile on a district-administered math screening test received the MR intervention from their teachers. We developed intervention units to build a conceptual foundation in a student-centered approach to Tier 2 instruction that included opportunities for students to engage in critical thinking as they generalized big ideas, participated in classroom discourse, and modeled multiplicative relationships with multiple representations. Preliminary data demonstrate the potential of the intervention to promote students’ MR skills. Instructional implications are discussed in terms of opportunities for these students to engage in grade-level mathematics content.     

The role of design ethics in maintaining students' privacy: A call to action to learning designers in higher education

Maintaining students' privacy in higher education, an integral aspect of learning design and technology integration, is not only a matter of policy and law but also a matter of design ethics. Similar to faculty educators, learning designers in higher education play a vital role in maintaining students' privacy by designing learning experiences that rely on online technology integration. Like other professional designers, they need to care for the humans they design for by not producing designs that infringe on their privacy, thus, not causing harm. Recognizing that widely used instructional design models are silent on the topic and do not address ethical considerations such as privacy, we focus this paper on how design ethics can be leveraged by learning designers in higher education in a practical manner, illustrated through authentic examples. We highlight where the ethical responsibility of learning designers comes into the foreground when maintaining students' privacy and well-being, especially in online settings. We outline an existing ethical decision-making framework and show how learning designers can use it as a call to action to protect the students they design for, strengthening their ethical design capacity.

Practitioner notes

What is already known about this topic

• Existing codes of ethical standards from well-known learning design organizations call upon learning designers to protect students' privacy without clear guidance on how to do so.
• Design ethics within learning design is often discussed in abstract ways with principles that are difficult to apply.
• Most, if not all, design models that learning design professionals have learned are either silent on design ethics and/or do not consider ethics as a valid dimension, thus, making design ethics mostly excluded from learning design graduate programs.
• Practical means for engaging in ethical design practice are scarce in the field.

What this paper adds

• A call for learning designers in higher education to maintain and protect students' privacy and well-being, strengthening their ethical design capacity.
• A demonstration of how to use a practical ethical decision-making framework as a designerly tool in designing for learning to maintain and protect students' privacy and well-being.
• Authentic examples—in the form of vignettes—of ethical dilemmas/issues that learning designers in higher education could face, focused on students' privacy.
• Methods—using a practical ethical decision-making framework—for learning design professionals in higher education, grounded in the philosophy of designers as the guarantors of designs, to be employed to detect situations where students' privacy and best interests are at risk.
• A demonstration of how learning designers could make stellar design decisions in service to the students they design for and not to the priorities of other design stakeholders.

Implications for practice and/or policy

• Higher education programs/institutions that prepare/employ learning designers ought to treat the topics of the designer's responsibility and design ethics more explicitly and practically as one of the means to maintain and protect students' privacy, in addition to law and policies.
• Learning designers in higher education ought to hold a powerful position in their professional practice to maintain and protect students' privacy and well-being, as an important aspect of their ethical design responsibilities.
• Learning designers in higher education ought to adopt a design thinking mindset in order to protect students' privacy by (1) challenging ideas and assumptions regarding technology integration in general and (2) detecting what is known in User Experience (UX) design as “dark patterns” in online course design.
