Concepts associated with the equality symbol

This paper looks at recent research dealing with uses of the equal sign and underlying notions of equivalence or non-equivalence among preschoolers (their intuitive nitions of equality), elementary and secondary school children, and college students. The idea that the equal sign is a do something signal (an operator symbol) persists throughout elementary school and even into junior high school. High schoolers' use of the equal sign in algebraic equations as a symbol for equivalence may be concealing a fairly tenuous grasp of the underlying relationship between the equal sign and the notion of equivalence, as indicated by some of the shortcut errors they make when solving equations.This article is based on a paper presented at Fourth International Conference of the International Group for the Psychology of Mathematics Education, Berkeley, California, August 1980.

The Organization of Reactivated Memory in Infancy

The specificity of memory retrieval by 3-month-old infants was examined in 3 experiments. All infants were trained in the mobile conjugate reinforcement paradigm to kick their feet to produce movement in an overhead crib mobile and were tested 2 weeks later. 24 hours prior to the test, subjects received a 3-min reminder treatment. The results of Experiment 1 demonstrated that only the moving training mobile alleviated forgetting after the 2-week retention interval; forgetting was not alleviated by exposure to the stationary training mobile or to the mobile stands and ribbon alone. The results of Experiments 2 and 3 demonstrated that, once retrieved, the reactivated memory was highly specific to the conditions of original training. Furthermore, the memory attributes that were the last to be forgotten (e.g., the general or global features) were the first to be retrieved following the reminder treatment. Conversely, those memory attributes that were forgotten first (e.g., the specific or local details) were the last to be retrieved. These findings have important implications for infant memory retrieval, reminiscence, and infantile amnesia.     

The cultural interface tension: doing Indigenous work in the academy

This article explores Vanessa Anthony-Stevens and Sammy Matsaw’s paper “The productive uncertainty of Indigenous and decolonizing methodologies in the preparation of interdisciplinary STEM researchers”. That paper reports on a small qualitative study on how STEM students in the field of natural resources management react to the inclusion of Indigenous ways of knowing in their interdisciplinary research methodologies course. The authors are engaging contested intersections of knowledge that are notoriously difficult to negotiate. I argue that the inclusion of Indigenous ‘ways of knowing’ into the water resource management curriculum is based on Morgan’s (in: McKinley, Smith (eds) Handbook of indigenous education, Springer, Singapore, pp 111–128, 2019. https://doi.org/10.1007/978-981-10-3899-0) idea of the ‘guest paradigm’. At the same time, and in contrast, I also argue that the inclusion of Indigenous knowledge in the curriculum cannot just occur in the classroom but needs to be considered at an institutional and individual level as well. The project should be seen as a small step within a wider Indigenous agenda of decolonizing the Eurocentric curriculum.

     

‘Wild’ girls? An exploration of ‘ladette’ cultures in secondary schools

‘Laddish’ attitudes and behaviours are central to current discourses on boys’ ‘underachievement’, as they are seen by many people to impede the progress of some boys in school. Whilst the vast majority of concern about ‘laddishness’ has, to date, focused upon boys, according to media reports there are now good reasons to worry about girls. Anecdotes from teachers and reports in the media suggest that some schoolgirls are now acting ‘laddishly’, that they are ‘ladettes’. This paper explores ‘ladette’ cultures in secondary schools, drawing upon interview data from100 pupils and 30 teachers. It tackles and discusses the following questions: (a) What does the term ‘ladette’ mean to pupils and teachers? (b) Do school‐aged ‘ladettes’ ‘exist’—and if so, what are they like inside and outside of school? (c) In what ways are ‘ladettes’ similar to, and different from, ‘lads’? (d) Are teachers concerned about ‘ladettes’? (e) Are ‘ladette’ behaviours on the increase?     

The relative effects of university success courses and individualized interventions for students with learning disabilities

Little is known about the relative effects of post‐secondary learning services for students with learning disabilities. We compared outcomes for students with learning disabilities who selected to: (1) take an academic learning success course (course‐intervention), (2) have regular individual interventions (high‐intervention) or (3) use services only as needed (low‐intervention). Pre‐ and post‐test comparisons revealed improvements in academic self‐efficacy and academic resourcefulness for students in the course‐ and high‐intervention groups. The course‐intervention group also showed decreases in their failure attributions to bad luck and increases in their general repertoire of learned resourcefulness skills in comparison to the high‐intervention group and had significantly higher year‐end GPAs in comparison to the low‐intervention group. Here we find positive outcomes for students with learning disabilities taking a course that teaches post‐secondary learning and academic skills.     

Empathy Is Associated With Dynamic Change in Prefrontal Brain Electrical Activity During Positive Emotion in Children

Empathy is the combined ability to interpret the emotional states of others and experience resultant, related emotions. The relation between prefrontal electroencephalographic asymmetry and emotion in children is well known. The association between positive emotion (assessed via parent report), empathy (measured via observation), and second-by-second brain electrical activity (recorded during a pleasurable task) was investigated using a sample of one hundred twenty-eight 6- to 10-year-old children. Contentment related to increasing left frontopolar activation ( p  < .05). Empathic concern and positive empathy related to increasing right frontopolar activation ( p s < .05). A second form of positive empathy related to increasing left dorsolateral activation ( p  < .05). This suggests that positive affect and (negative and positive) empathy both relate to changes in prefrontal activity during a pleasurable task.
