Do teacher instructional practices shape children's academic self-concept and interest in mathematics and science? Evidence from TIMSS 2015

Children possess different beliefs regarding their ability to succeed in math and science, as well as different levels of enjoyment and interest in these topics. These motivational processes are important because they often shape learning-related behaviours which in turn predict academic outcomes, over and above previous performance. But, what are the potential sources of influence that could explain individual differences in children's academic self-concept and interest in math and science? In this registered report, we adopted a situated expectancy-value theory framework to examine the potential role of teacher instructional practices that emphasize conceptual understanding in enhancing these motivational processes. We focused on practices emphasizing conceptual understanding given science-driven recommendations to implement them across the United States. Contrary to our hypotheses, a multilevel analysis of grade 4 U.S. data from the 2015 release of the Trends in International Mathematics and Science Study (TIMSS) revealed that the self-reported frequency of instructional practices emphasizing conceptual understanding were unrelated to math or science self-concept and interest. Our null findings prompt greater attention to other factors, such as the quality and implementation of instructional practices, differences between instructional goals and actual practices, and classroom composition, that could enhance ability beliefs and values in math and science.     

Using Insights from Applied Moral Psychology to Promote Ethical Behavior Among Engineering Students and Professional Engineers

In this essay I discuss a novel engineering ethics class that has the potential to significantly decrease the likelihood that students (and professionals) will inadvertently or unintentionally act unethically in the future. This class is different from standard engineering ethics classes in that it focuses on the issue of why people act unethically and how students (and professionals) can avoid a variety of hurdles to ethical behavior. I do not deny that it is important for students to develop cogent moral reasoning and ethical decision-making as taught in traditional college-level ethics classes, but as an educator, I aim to help students apply moral reasoning in specific, real-life situations so they are able to make ethical decisions and act ethically in their academic careers and after they graduate. Research in moral psychology provides evidence that many seemingly irrelevant situational factors affect the moral judgment of most moral agents and frequently lead agents to unintentionally or inadvertently act wrongly. I argue that, in addition to teaching college students moral reasoning and ethical decision-making, it is important to: 1. Teach students about psychological and situational factors that affect people’s ethical judgments/behaviors in the sometimes stressful, emotion-laden environment of the workplace; 2. Guide students to engage in critical reflection about the sorts of situations they personally might find ethically challenging before they encounter those situations; and 3. Provide students with strategies to help them avoid future unethical behavior when they encounter these situations in school and in the workplace.     

Error-related electrocortical responses in 10-year-old children and young adults

Recent anatomical and electrophysiological evidence suggests that the anterior cingulate cortex (ACC) is relatively late to mature. This brain region appears to be critical for monitoring, evaluating, and adjusting ongoing behaviors. This monitoring elicits characteristic ERP components including the error-related negativity (ERN), error positivity (Pe) and correct-related negativity (CRN), with the ERN clearly relating to activation of the ACC; however, little attention has been paid to the examination of these ERP components in children. The present study examined developmental differences in the ERN, Pe, and CRN in normal 10-year-old children and young adults in a standard visual flanker task. We found that children had smaller ERNs than adults, with no between-group differences on the Pe, and some ambiguity concerning the CRN. Results provide electrophysiological support either for late maturation of the ACC or late involvement of the ACC in response monitoring. Results also suggest that there is some functional independence of response-monitoring ERP components. Error-related ERPs may be a useful tool in studying the development of this brain region and its role in behavior in normal and atypical development.     

The Contributions of Oral and Silent Reading Fluency to Reading Comprehension

Silent reading fluency has received limited attention in the school-based literatures across the past decade. We fill this gap by examining both oral and silent reading fluency and their relation to overall abilities in reading comprehension in fourth-grade students. Lower-level reading skills (word reading, rapid automatic naming) and vocabulary were included in structural equation models in order to determine their impact on reading fluency and comprehension. Results suggested that oral and silent reading fluency represent separate constructs, but only oral reading fluency contributed to reading comprehension. Vocabulary was found to contribute uniquely to comprehension even after controlling for reading fluency.     

An Experiment in the Prevention of Delinquency by Edwin Powers and Helen Witmer

A longitudinal clinical outcome study based primarily on a questionnaire method is the purpose of this two part paper. Techniques and approaches honed from fifteen years of para-analytic experience with one continuous Saturday morning group (seventy-five adolescents and young adults) are highlighted in this first part. Attention is focused on such pertinent issues as: lateness, selection, duration, individual sessions, physical setting, outside contacts, decreasing anxiety, parents and the important involvement of a female cotherapist. Catalyzing agents in the form of art therapy and mini-silent groups are described. The psychological position is presented for an age-mixed group (adolescents and young adults—age range twenty to thirty) to facilitate a natural flow of topics in the group dialogue rather than a “topic” format.
