Mentoring interdisciplinary undergraduate students via a team effort

We describe how a team approach that we developed as a mentoring strategy can be used to recruit, advance, and guide students to be more interested in the interdisciplinary field of mathematical biology, and lead to success in undergraduate research in this field. Students are introduced to research in their first semester via lab rotations. Their participation in the research of four faculty members-two from biology and two from mathematics-gives them a first-hand overview of research in quantitative biology and also some initial experience in research itself. However, one of the primary goals of the lab rotation experience is that of developing teams of students and faculty that combine mathematics and statistics with biology and the life sciences, teams that subsequently mentor undergraduate research in genuine interdisciplinary environments. Thus, the team concept serves not only as a means of establishing interdisciplinary research, but also as a means of incorporating new students into existing research efforts that will then track those students into meaningful research of their own. We report how the team concept is used to support undergraduate research in mathematical biology and what types of team-building strategies have worked for us.     

Some possible effects of behaviour management training on teacher confidence and competence: evidence from a study of primary school teachers in Hong Kong

This study aims to explore the relationships between the extent and perceived quality of teachers’ experience of training in behaviour management (BM), and their awareness of the nature and extent of behavioural problems among school students, and their confidence in their own competence to deal with such problems. Teachers (n = 183) from Hong Kong primary schools were surveyed. The results showed that gender, age and whether teachers have received training had no significant influence on teachers’ awareness, conception and confidence regarding BM. A negative correlation was found between teachers’ levels of satisfaction in relation to their training experiences and their perceptions of the level of problematic behaviours among students, and the impact of students’ problematic behaviour on their teaching. A positive correlation was found between teachers’ levels of satisfaction in relation to their training experiences and their confidence in their own competence to deal with students’ problematic behaviour.     

Assessing the Worth of the College Degree on Self-perceived Police Performance

Many formal policies have suggested that officers need a college degree; however, policies forced little change in practices of American police organizations. Six hundred-fifty patrol officers employed in 12 medium-sized police departments in three Midwestern states were surveyed as to their current educational attainment and job performance. The purpose of this study was to determine the relationship between educational level and police performance.     

Design-Based Research Within the Constraints of Practice: AlgebraByExample

Superintendents from districts in the Minority Student Achievement Network (MSAN) challenged the Strategic Education Research Partnership (SERP) to identify an approach to narrowing the minority student achievement gap in Algebra 1 without isolating minority students for intervention. SERP partnered with 8 MSAN districts and researchers from 3 universities to design and rigorously test AlgebraByExample, a set of 42 Algebra 1 assignments with interleaved worked examples that target common misconceptions and errors. In a year-long random-assignment study, students who received AlgebraByExample assignments had an average 7 percentage point boost on a posttest containing released items from state assessments, and students in the bottom half of the performance distribution where minority students are disproportionately concentrated had an average 10 percentage point boost on a researcher-designed assessment of conceptual understanding. AlgebraByExample is easily incorporated into any existing curriculum, and naturally serves as a launch point for mathematically rich discussion.     

Advancing scholarship on anti-racism within developmental science: Reflections on the special section and recommendations for future research

To date, theoretical and conceptual scholarship on anti-racism has been advanced through leading contributions from several disciplines (e.g., sociology, education, psychology). Still, there remain fewer empirical studies on anti-racism constructs, and we know little about the development of anti-racism among diverse youth across key stages of development. In this special section of Child Development, we sought to address this gap by highlighting scholarship in developmental science that attends to the development of anti-racism in children across contexts (e.g., families, schools) and developmental stages (e.g., early childhood through emerging adulthood). In our introduction to the special section, we review the collective contributions of included studies and outline recommendations for future research in the development of anti-racism in youth.     

Field and laboratory measurements of softball player swing speed and bat performance

The swing speed of the bat is one of the most important factors affecting the hit-ball speed. Most field studies tend to focus on measuring ball speed, which is easier to measure and quantify than bat speed. For this reason, relatively little data exist describing bat motion in field conditions. The following describes a relatively large swing speed field study involving bats of the same model with nearly constant weight and varying inertia. The study was conducted using right-handed batters on a regulation outdoor field with a live pitcher. Swing speed was measured by tracking markers on the bat with two high-speed video cameras so that the bat markers could be traced in three-dimensional space. The ball motion was tracked using the same high-speed video cameras and a three-dimensional Doppler radar system. Bat swing speed was observed to be proportional to the batter skill level and the normalised swing speed increased with decreasing bat inertia. The bat centre of rotation during impact was close to the knob of the bat. The bats were tested under controlled laboratory conditions using a standardised performance test. The field and laboratory results showed good agreement including the hit-ball speed and the subtle effect of bat inertia on the maximum performance location. The vibrational response of the bats was considered using modal analysis. The maximum performance location was correlated with the node of the first vibrational mode.     

The impact of current developments in post-compulsory education on young people with learning difficulties and/or disabilities

Deborah Cooper, Economy and Learning Manager with Milton Keynes Council and previously Chief Executive of Skill: National Bureau for Students with Disabilities, considers ways in which opportunities for children with special educational needs in England and Wales are being affected by current developments in post-compulsory education.     

The disguise of self‐disclosure: The relationship ruse of a Soviet Spy

The verbal disclosures of a Soviet spy masquerading as a university student are compared to those of three other group members involved in a semester‐long project. Audio‐tapes of six group meetings provide a unique opportunity to assess the relationship deception of this proficient deceiver. His communication is characterized by strategic disclosures designed to create a false impression and, thereby, to divert attention from his secret role. His conversation reveals more frequent control disclosures, attitude disclosures, personal disclosures, and dramatic disclosures than other group members. The spy also verbalized significantly more knowledge disclosures than all but one other peer. The frequency and content of his disclosures identify, in part, the communicative strategy of his disguise, whereby he drew considerable attention to himself and, thus, appeared transparent. The results underscore the importance of looking beyond the appearance of disclosures when attempting to identify relationship deception.
