Perceptions of Reform-Based Teaching and Learning in a College Mathematics Class

This study investigated, from the students',professor's, and researchers' perspectives, the effects of a reform-based introductory undergraduate mathematics course, and the efforts of a mathematics professor to teach such a course. The class had been designed for teacher candidates of middle school mathematics and science (Grades 4 to 8) but was open to all qualified students. We addressed the following research question: What perceptions about learning and teaching mathematics emerged through the participants' experiences in a reform-based mathematics course? Results of the analysis of the data suggested that the teacher candidates and the professor took an important first step toward enculturation into a reform-based vision of mathematics learning and teaching. Implications for mathematics faculty and teacher education faculty interested in promoting reform-based mathematics are presented.     

Using guided notes with academically at‐risk high school students during a remedial summer social studies class

This study evaluated the effects guided notes on the performance of academically at‐risk high school students during a remedial summer American History class. The study compared students' own notetaking strategies with that of short‐ and long‐form guided notes. Three students were selected for data collection due to their low baseline notetaking accuracy and quiz scores and a history of severe learning problems: One was enrolled in special education programs for developmental disabilities and the other two were enrolled in English as a Second Language programs (ESL). A modified ABAB reversal design with an imbedded alternating treatments design during intervention (A. E. Kazdin, 1982) was used to compare the effects of students' notetaking accuracy and daily quiz scores while taking their own notes with the effects of responding under the short‐ and long‐form guided notes. The results indicated that both guided notes procedures were successful at increasing the accuracy of students' notes, improving session quiz scores, and were overwhelmingly preferred when compared with students taking their own notes. Differences were the number of concepts written correctly. Practical considerations and implications for adoption in the classroom were discussed. © 1999 John Wiley & Sons, Inc.     

Development and factor structure of a self-report measure for assessing internalizing symptoms of elementary-age children

The development and factor structure of the Internalizing Symptoms Scale for Children (ISSC), a new self-report measure for assessing internalizing symptomatology in children, is detailed. Development of the ISSC was driven by the lack of a children's self-report instrument designed specifically to assess the broad domain of internalizing symptomatology, as well as research findings showing a high degree of comorbidity among internalizing syndromes (e.g., depression, anxiety, somatic complaints, social withdrawal). Thorough and methodologically rigorous procedures were employed during the development of the ISSC to ensure strong content validity as well as clinical utility. Exploratory and confirmatory factor analytic procedures were utilized on the 54-item ISSC research protocol, resulting in a strong two factor solution for the 48 items retained. Factor 1, Negative Affect/General Distress, includes items that indicate the presence of internalizing symptoms, or in some cases, the absence of optimistic or functional emotional states. Factor 2, Positive Affect, includes items describing positive affect incompatible with internalizing symptoms, or in some cases, items that reflect the absence of internalizing symptoms. Results of the factor analyses are discussed in terms of previous research on affectivity and specific internalizing syndromes or disorders. Potential uses of the ISSC, as well as further research needed, are described. Implications of the present investigation for future assessment and classification studies in the area of child psychopathology are reviewed. © 1997 John Wiley & Sons, Inc.     

Injury rates and characteristics in recreational,elite student and professional dancers: A systematic review

The purpose of this study was to systematically review the literature and synthesise the evidence on injury rates and characteristics in recreational, elite student, and professional dancers. Five online databases were searched from inception to January 2018 and screened by two independent reviewers. Primary research studies were eligible for inclusion if they reported injury rates in recreational, elite student, and/or professional dancers of any genre and measured individual dance exposure at the hour, event, or day level. Sixteen studies were included, with only three studies incorporating recreational dancers. Reported injury incidence rates were less than 5 injuries per 1,000 dance hours, however substantially different definitions and methods for measuring injury and dance exposure were used. Based on the current evidence there is not an identifiable difference in injury rate or characteristics between recreational, elite student, and professional dancers. However, there remains a lack of high quality comprehensive data available across levels and genres of dance participation, and greater focus on consistency and completeness of reporting in dance injury research is still required.     

Is sport good for older adults? A systematic review of psychosocial outcomes of older adults’ sport participation

Although sport is promoted as a vehicle to enhance health and well-being throughout the life course, little is known about the psychosocial benefits and costs associated with sport participation in older adulthood. A mixed studies systematic review of English-language, peer-reviewed, original research articles (from the earliest record until March 2015) was undertaken to identify psychosocial outcomes of sport for adults over age 65 and to determine whether sport provides psychosocial outcomes that are distinct from other forms of physical activity. Results suggest sport involvement later in life was related to ageing, cognitive/perceptual, emotional, social, and motivational outcomes but it remains unclear whether these effects were solely related to participation in sport. Additional work with increased attention to methodological design and participant recruitment is needed to better understand psychosocial outcomes of older adults’ sport participation and to inform potential interventions. Recommendations to enhance the quality of future studies in the area are discussed.     

An objective method of specification for sensitometric curves of photographic papers

A system of numerical specification of the sensitometric curves of photographic papers is described. Comparison of original curves and their reproductions, made by a new curve duplicator from specifications, shows that the system is satisfactory for production control.
