Biology Intensive Orientation for Students (BIOS): a biology "boot camp"

The Biology Intensive Orientation for Students (BIOS) Program was designed to assess the impact of a 5-d intensive prefreshman program on success and retention of biological science majors at Louisiana State University. The 2005 pilot program combined content lectures and examinations for BIOL 1201, Introductory Biology for Science Majors, as well as learning styles assessments and informational sessions to provide the students with a preview of the requirements of biology and the pace of college. Students were tracked after their BIOS participation, and their progress was compared with a control group composed of students on the BIOS waiting list and a group of BIOL 1201 students who were identified as the academic matches to the BIOS participants (high school GPA, ACT score, and gender). The BIOS participants performed significantly better on the first and second exams, they had a higher course average, and they had a higher final grade than the control group. These students also had higher success rates (grade of “A,” “B,” or “C”) during both the fall and spring semesters and remained on track through the first semester of their sophomore year to graduate in 4 yr at a significantly higher rate than the control group.     

A mediation meta-analysis of the role of maternal responsivity in the association between socioeconomic risk and children’s language

This meta-analysis tested maternal responsivity as a mediator of the association between socioeconomic risk and children's preschool language abilities. The search included studies up to 2017 and meta-analytic structural equation modeling, allowed us to examine the magnitude of the indirect effect across 17 studies (k = 19). The meta-analysis included 6433 predominantly White, English speaking children (M_age = 36 months; 50% female) from Western, industrialized countries. All paths in the model were statistically significant, notably, the indirect effect was significant (b = −.052), showing that maternal responsivity may be a proximal intervening variable between socioeconomic risk and children's language development. Moderator analyses found that the indirect effect was stronger for sensitive parenting than warmth and when parenting was assessed in the family home.     

Unmasking: on violence, masculinity, and superheroes in science education

Through exploration of public mask/private face, the authors trouble violence and its role in science education through three media: schools, masculinity, and science acknowledging a violence of hate, but dwelling on a violence of caring. In schools, there is the poisonous ??for your own good?? pedagogy that becomes a ??for your own good?? curriculum or a coercive curriculum for science teaching and learning; however, the antithetical curriculum of I??m here entails violence??the shedding of the public mask and the exposing of the private face. Violence, likewise, becomes social and political capital for masculinity that is a pubic mask for private face. Lastly, science, in its self-identified cultural, political and educational form of a superhero, creates permanent harm most often as palatable violence in order to save and to redeem not the private face, but the public mask. The authors conclude that they do not know what violence to say one should not do, but they know the much of the violence has been and is being committed. All for which we can hope is not that we cease all violence or better yet not hate, but that we violently love.     

Minority Students and the Health Professions

Individuals from minority groups are underrepresented in medical school. . . . We must achieve a 12 percent representation of these individuals in the health professions . . . in order to equate the number of students from minority groups in medical school with the percentage of their distribution in the population at large.

Personality and its Relationship to Success in Professional Baseball

Purpose: The relationships among students' self-efficacy, 2 × 2 achievement goals (mastery-approach [MAp], mastery-avoidance [MAv], performance-approach [PAp], and performance-avoidance goals), and achievement performance remain largely unanswered. We tested a model of the mediating role of self-efficacy on the relationship between 2 × 2 achievement goals and cardiorespiratory fitness. Method: A sample of 276 middle school students (115 boys and 161 girls; 91 sixth graders, 87 seventh graders, and 98 eighth graders), aged 12 to 15 years (M _age = 13.34, SD = 0.96), responded to the Achievement Goals Questionnaire (Conroy, Elliot, &; Hofer, 2003) and Self-Efficacy Questionnaire (Gao, Newton, &; Carson, 2008) referenced to the fitness test. Their cardiorespiratory fitness was assessed via the Progressive Aerobic Cardiorespiratory Endurance Run (PACER) 3 days later. Results: Structural equation modeling demonstrated an acceptable model fit to the data, χ ² (2, N = 105) = 1.66. Self-efficacy had a statistically significant direct effect on the PACER after controlling for the effects of the achievement goals (γ _{self-efficacy-PACER}  = .21). MAv and PAp also had direct effects on PACER performance (γ _MAv-PACER  = ? .24, and γ _PAp-PACER  = .24, respectively). MAp failed to exert direct effect on the PACER. However, the indirect effect of MAp on the PACER via self-efficacy was small although it was statistically significant. Additionally, the indirect effects of MAv and PAp on PACER through self-efficacy were not significant. Conclusions: Students' self-efficacy fully mediated the effect of MAp on fitness performance, as well as partially mediated the effects of MAv and PAp on cardiorespiratory fitness performance. Study implications are provided for educators and practitioners.     

Relationship between a 14-Day Recall Measure of Leisure-Time Physical Activity and a Submaximal Test of Physical Work Capacity in a Population Sample of Australian Adults

Abstract

This paper reports on the validity of a 14-day recall measure of leisure time physical activity (LTPA) in a sample of Australian adults (N = 986). Submaximal cycle ergometry was used to assess physical work capacity per kilogram of body mass (pwc75/kg). The self-report energy expenditure estimates were used to categorize respondents as vigorously active, moderately active, and low active/sedentary. Multiple regression analyses showed that pwc75/kg increased significantly across energy expenditure categories for adults aged less than 40 years; that the vigorous and moderate activity categories had greater mean pwc75/kg values than the low/sedentary category for 40 to 59-year-olds; and, that there were no differences in pwc75/kg between activity categories for those aged 60 years or older.     

An Australian Version of the Neighborhood Environment Walkability Scale: Validity Evidence

This study examined validity evidence for the Australian version of the Neighborhood Environment Walkability Scale (NEWS-AU). A stratified two-stage cluster sampling design was used to recruit 2,650 adults from Adelaide (Australia). The sample was drawn from residential addresses within eight high-walkable and eight low-walkable suburbs matched for socio-economic status (SES). Neighborhood walkability was measured using Geographic Information Systems data on dwelling density, intersection density, net retail area, and land-use mix. Participants completed the NEWS-AU and reported weekly minutes of walking for transport and recreation (International Physical Activity Questionnaire [IPAQ]). Multilevel confirmatory factor analysis (MCFA) was used to define the individual- and Census Collection District (CCD)-level measurement model of the NEWS-AU. Seven individual-level and five CCD-level factors were identified. These measurement models were somewhat similar to those of the original Neighborhood Environment Walkability Scale (NEWS). Patterns of associations between the NEWS-AU factors/scales and the walking measures provided some validity evidence for the instrument.     

The role of children's lay theories about the malleability of human attributes in beliefs about and volunteering for disadvantaged groups

Two studies with 9- to 12-year-old children supported the hypothesis that lay theories about the malleability of human traits impact judgments of and behavior toward groups in need of volunteer help. The more children endorsed an incremental view (attributes can change), the more they reported liking, desiring social contact with, and perceiving similarity between themselves and a disadvantaged outgroup (homeless, UNICEF-funded children). Moreover, children endorsing more of a malleable view reported greater past volunteering, active participation in collecting money for a UNICEF event, and intentions to volunteer again. These findings held when controlling for the effects of participants' gender, self-esteem, and perceived social pressure to help others. How a malleable view and intergroup volunteerism may be mutually sustaining is discussed.     

Reading comprehension strategy instruction and attribution retraining for secondary students with learning and other mild disabilities

A pre-post experimental design with 6-week delayed posttest was implemented to investigate the effects of reading comprehension strategy (RCS) instruction with and without attribution retraining (AR) on reading outcomes for seventh, eighth, and ninth graders with learning and other mild disabilities. Students were randomly assigned to one of three treatments: RCS+AR, RCS, or a Read Naturally (Ihnot, 1992) comparison condition. Results indicated that compared to the comparison group, both strategy instruction groups performed better on a summarization measure of comprehension after treatment producing large effect sizes. Both groups also performed better after a 6-week delay; however, only the RCS+AR group maintained a large effect size. In addition, RCS+AR students displayed higher attributions for reading success at post- and delayed posttesting. Implications for practice and future research are discussed.     

Teaching in the borderland: critical practices in foundations courses

Using first-person accounts of classroom experiences, five professors examine the intersection of social foundations and borderland theory and their efforts to move students through resistance to understanding and affirmation of sociocultural diversity. The authors present this paper in two parts, the first providing examples of using a borderland approach within the classroom and the second providing illustrations moving these borderland strategies beyond the classroom. In each case, authors show the interwoven nature of pedagogy, identity, knowledge, and experience as they work to connect theory and practice. All of the institutions represented have majority white populations, and many do not reflect the diversity of the communities in which they are situated. The need for borderland practices in social foundations courses is urgent in these areas. These pedagogical reflections, although not meant to be recipes for success, provide examples of practices that can serve to meet the growing demands from schools and communities for culturally competent, socially aware teacher–leaders, and reaffirm the critical importance of social foundations in teacher education.
