Mathematics and Science Learning Opportunities in Preschool Classrooms

Research Findings: The present study observed and coded instruction in 65 preschool classrooms to examine (a) overall amounts and (b) types of mathematics and science learning opportunities experienced by preschool children as well as (c) the extent to which these opportunities were associated with classroom and program characteristics. Results indicated that children were afforded an average of 24 and 26 min of mathematics and science learning opportunities, respectively, corresponding to spending approximately 25% of total instructional time in each domain. Considerable variability existed, however, in the amounts and types of mathematics and science opportunities provided to children in their classrooms; to some extent, this variability was associated with teachers' years of experience, teachers' levels of education, and the socioeconomic status of children served in the program. Practice or Policy: Although results suggest greater integration of mathematics and science in preschool classrooms than previously established, there was considerable diversity in the amounts and types of learning opportunities provided in the preschool classrooms. Affording mathematics and science experiences to all preschool children as outlined in professional and state standards may require additional professional development aimed at increasing preschool teachers' understanding and implementation of learning opportunities in these 2 domains in their classrooms.     

Revictimization Through Education: Does Learning About Victimization Lead to Anxiety and Identification as a Victim Among College Students?

Researchers generally accept that victims may experience revictimization in the criminal justice system when they relive victimization experiences while recounting the victimization to criminal justice officials. In addition, scholars have drawn attention to the need to be sensitive in victimology courses and other courses focusing on victimization. In this study, the authors examine whether victims experience forms of revictimization when learning about victimization in college courses. Attention is also given to whether learning about victimization promotes self-identification as a victim. Our findings suggest that minor forms of revictimization may occur. A sizeable portion of the students reported learning that they were victimized in the past as a result of the course material. Implications for teaching victimology are provided.     

Multidimensional Perfectionism,Coping, and Depression: Differential Prediction of Depression Symptoms by Perfectionism Type

Perfectionism has consistently been implicated as a significant contributor to negative outcomes, including depression, in college student populations. This study examined the relationship between multidimensional perfectionism, coping, and depression in a sample of 405 undergraduate students. Maladaptive perfectionists, adaptive perfectionists, and nonperfectionist college students differed significantly on levels of depression and exhibited different patterns of coping. Avoidant coping mediated the relationship between both adaptive and maladaptive perfectionism and depression.     

Identification of Core Competencies for an Undergraduate Food Safety Curriculum Using a Modified Delphi Approach

Identification of core competencies for undergraduates in food safety is critical to assure courses and curricula are appropriate in maintaining a well‐qualified food safety workforce. The purpose of this study was to identify and refine core competencies relevant to postsecondary food safety education using a modified Delphi method. Twenty‐nine experts representing food safety professionals in academia, government, and industry were given 2 rounds of questionnaires that specified initial food safety competencies, core domains, and subdomains. Competencies were defined as a set of skills, knowledge, and abilities that correlate to success of a trainee. The framework for which competencies were classified consisted of (1) core domains, defined as broad food safety subjects; and (2) subdomains, or more specific food safety subjects. The expert panel used a 5‐point Likert scale with an acceptance criterion, or consensus, of 75%, with a rating of “4” or greater. After 2 rounds of questionnaires and revisions from the expert panel, 5 core domains were established: (1) Food Production, Manufacturing, Retail, and Consumer; (2) Foodborne Hazards; (3) Public Health; (4) Legislation and Policy; and (5) Communication and Education. Specific responses from the experts highlighted areas in which further curriculum revision would be beneficial. This study provides a framework for the development of a vetted, standardized undergraduate food safety curriculum. The Delphi method, with its inclusion of professionals representing various sectors of food safety, provided relevant perspectives for curriculum design, and also allowed participants the opportunity to contribute to the education of future food safety professionals.     

In a daily time–place learning task,time is only used as a discriminative stimulus if each daily session is associated with a distinct spatial location

It is difficult for rats to acquire daily time–place (TP) learning tasks. One theory suggests that rats do not use time of day as a stimulus signaling a specific response. In the present study, we tested rats’ ability to use time of day as a discriminative stimulus. A fixed-interval procedure was used in which one lever provided reinforcement on a FI-5-s schedule in morning sessions, and the same lever provided reinforcement on a FI-30-s schedule in afternoon sessions. Because only one place was used in this paradigm, the rats could only use time of day to acquire the task. Mean responses during the first 5 s of the first trial in each session indicated that the rats did not discriminate between the two sessions. In Phase II, a different lever location was used for each of the two daily sessions, which meant that both spatial and temporal information could be used to acquire the task. The rats readily acquired the task in this phase, and probe trials indicated that the rats were using a combination of spatial and temporal information to discriminate between the two different trial types. When the spatial cue was removed in Phase III, rats no longer discriminated the two sessions, suggesting that time can only be used as a discriminative stimulus when each daily session is associated with a distinct spatial location.     

INTERACT: building a virtual community of practice to enhance teachers’ intercultural professional development

This project focuses on the design and implementation of an online professional development platform tailored to teachers’ needs to improve and promote their intercultural knowledge. Drawing upon the framework of virtual communities of practice, the project escapes from traditional professional development programmes. Although a total of 103 teachers participated in the project, in the implementation phase we carried out observations and interviews with a sub-sample of 40 teachers. Research findings indicate the generation of new knowledge regarding new pedagogical practices with respect to intercultural education as well as an increased collaboration among all involved stakeholders. Through the active involvement in the INTERACT platform, teachers became reflective practitioners by having opportunities to raise their voice and share views on their intercultural practices.     

Smooth Transition for Advancement to Graduate Education (STAGE) for Underrepresented Groups in the Mathematical Sciences Pilot Project: Broadening Participation through Mentoring

The Smooth Transition for Advancement to Graduate Education (STAGE) project was a three-year pilot project designed to mentor undergraduate students primarily from under-represented groups in the mathematical sciences. The STAGE pilot project focused on mentoring students as they transitioned from undergraduate education to either graduate school or a career in the STEM workforce. We discuss the various mentoring structures, the STAGE pilot utilized, and how those structures affected programmatic outcomes. In addition, we discuss challenges we faced in mentoring undergraduates and special considerations we made when mentoring students from under-represented groups.     

Trial and Error: How Student Affairs Staff in Community Colleges Learn to Supervise

Supervisory skills play an important role in individual staff development and the achievement of organizational objectives. These skills are vital to professionals in community college student affairs, who support a diverse student population and a wide array of programming. This study was conducted to describe the kind of supervisory training experience student affairs professionals received. Through interviews with community college student affairs professionals, we found that many experienced a lack of formal training and acquired supervisory skills over time on the job, through trial and error, and from workshops.     

The relationship between physical activity and self-efficacy in children with disabilities

Abstract

The main purpose of this study is to investigate whether self-efficacy in children with disabilities could be strengthened through targeted and adapted physical activities led by specially educated leaders. Children and Youth Physical Self-Perception Profile (CY-PSPP) scale were used. The study includes 45 children of 8–14 years of age with different types of impairments. The children participated in training sessions twice a week and tried out 13 different physical activities during eight months. The median in this study of total self-efficacy was 104 points, which can be compared to median points varying between 100 and 107 in previous studies based on children without disabilities. Furthermore, there was a statistically significant increase of the means in four out of six different domains of self-efficacy before and after the study was carried out. Key findings indicated that this model is successful in strengthening the children’s self-efficacy and that their perceived self-efficacy was equal to that of children without disabilities.     

Developmental patterns of children's shyness: Relations with physiological,emotional, and regulatory responses to being treated unfairly

The dysregulation of social fear has been widely studied in children's shyness, but we know little about how shy children regulate during unfair treatment. We first characterized developmental patterns of children's shyness (N = 304, n_girls = 153; 74% White, 26% Other) across 2 (M_age = 2.07), 3 (M_age = 3.08), 4 (M_age = 4.08), and 6 (M_age = 6.58) years of age. Data collection occurred from 2007 to 2014. At age 6, the high stable group had higher cardiac vagal withdrawal and lower expressed sadness and approach-related regulatory strategy than the low stable group when being treated unfairly. Although shy children may be more physiologically impacted by being treated unfairly, they may mask their sadness to signal appeasement.
