An investigation of Grade 5 children's knowledge of the doubling rule in spelling

The goal of this study was to investigate Grade 5 children's knowledge of a common word pattern in English, to double the final consonant of a one‐syllable word when adding –ed. Significant correlations were found between –ed spelling and general spelling ability, as well as correct pronunciation of –ed words in isolated word reading and spelling. The correlation between –ed spelling and –ed word reading (r=0.31) is lower than one would expect to find in general spelling and reading ability. Individual interviews were conducted to assess children's explicit awareness of the doubling rule, followed by a measure of consistency in spelling a selected number of –ed words. Performance on an artificial grammar task indicated a correlation between implicit learning of nonsense letter strings and spelling ability. Overall results point to the unstable nature of children's knowledge of the doubling rule. Implications for instruction are discussed.     

Timing of interfering events in one-trial serial overshadowing of a taste aversion

This set of experiments examined the question of when a stimulus would be most effective in overshadowing the acquisition of long-delay taste aversion learning. In Experiment 1 rats drank sucrose, the target solution, followed by a hydrochloric acid (HCl) solution before lithium injection some time later; HCl was presented either early or late in the interval. The late condition produced greater overshadowing than the early condition. The importance of the HCl-injection interval was confirmed by Experiment 2, in which the sucrose-injection interval was varied. Experiment 3 found that even placement in a different context – an event that normally produces little overshadowing of a CTA – produced one-trial overshadowing of a sucrose aversion as long as the context was novel and exposure to it occurred immediately before lithium injection. No current theoretical account of one-trial overshadowing predicts that a late event produces more overshadowing than an early event. This result can, however, be accommodated within a modified version of the Rescorla-Wagner model.     

Effects of class size on alternative educational outcomes across disciplines

This is the first study to use self-reported ratings of student learning, instructor recommendations, and course recommendations as the outcome measure to estimate class size effects, doing so across 24 disciplines. Fixed-effects models controlling for heterogeneous courses and instructors reveal that increasing enrollment has negative and significant effects on student satisfaction in Sociology, Political Science, Computer Science and Engineering, and Mechanical and Aerospace Engineering. Educational outcomes in Linguistics, Psychology, Biological Sciences, Chemistry, Math, Physics, Cognitive Sciences, Visual Arts, History, and Philosophy are unaffected by class size. Other disciplines, including Economics, have inconclusive findings. No discipline benefits from increasing enrollment.     

A case for a collaborative classroom

Collaboration is an important skill. But what do we do when students just can't (or won't) work together effectively? Dorothy A. Osterholt and Katherine Barratt share their structured, supportive approach.     

Learning to collaborate: Can young children develop better communication strategies through collaboration with a more popular peer

Unpopular children are known to have poor communication skills and experience difficulty in collaborative situations. This study investigated whether pairing unpopular, 5 to 6 year-old, children with a more popular peer would promote more effective collaboration. The study also investigated differences in popular and unpopular children’s verbal and non-verbal communication. Thirty-six girls and 36 boys were placed in one of 12 popular, 12 unpopular or 12 mixed pairs. There were no mixed gender pairs. Children were filmed playing a collaborative game. Collaboration in popular pairs was more successful and less disputational than in unpopular pairs. Boys in unpopular pairs broke the rules of the game more often, argued more and did not monitoring their partners’ facial expressions effectively. With popular partners they argued less, were more likely to elaborate disagreements, looked at their partner for longer, smiled more and were more likely to offer him a small toy. Unpopular girls’ interactions were not markedly disruptive but they clearly benefited from being paired with a child with good communication skills. Popular girls modified their behaviour to take into account an unpopular partner’s need for support. These findings suggest that pairing popular and unpopular children may be a useful classroom organisation strategy.

Addressing violence against teachers: A social-ecological analysis of teachers' perspectives

Much research has been dedicated to supporting school communities in combating the problem of school violence. However, violence directed toward teachers is under-investigated, and knowledge of how to support teachers is limited. This qualitative study used conventional content analysis to assess teachers' recommendations for preventing and improving the response to teacher-directed violence. The sample included 245 prekindergarten through 12th grade teachers, all of whom experienced school violence and participated in a larger national survey study on violence against teachers. Using a social-ecological framework and conventional content analysis, teacher recommendations for addressing teacher victimization were identified and organized at the individual, school, community, and society levels. Themes around conflict resolution strategies; improving policies, resources, and relationships with administrators; increasing parental involvement; and changing culture and laws were highlighted. Implications for research, practice, and policy are discussed.
