“回收”爸爸

我成长于七十年代初,那时,离婚尚未对核心家庭产生严重的影响。整个小学阶段,我仅遇到过一个来自破裂家庭的小孩,而在我看来,她是让人好奇的异类。同学们似乎都害怕她,好像她会传染似的。我父亲已经去世,所以离婚似乎与我无关。我四岁时,父亲就去世了,虽然我偶尔会密谋想要让亨利·方达成为我的继父,但是我和母亲相依为命,     

Elementary Science Students’ Motivation and Learning Strategy Use: Constructivist Classroom Contextual Factors in a Life Science Laboratory and a Traditional Classroom

The purpose of this study was to describe the influence of constructivist classroom contextual factors in a life science laboratory and a traditional science classroom on elementary students’ motivation and learning strategy use. The Constructivist Teaching Inventory was used to examine classroom contextual factors. The Motivated Strategies for Learning Questionnaire was used to examine student motivation and learning strategies. A Wilcoxon nonparametric test determined that constructivist teaching practices were found to occur more often in the life laboratory than in the regular classroom. Although constructivist teaching practices increased at each observation time in both the regular classroom and in the life laboratory, a Friedman test determined that they were not statistically significant increases. Paired sample t tests determined that student motivation and learning strategies were higher in the life laboratory than in the regular classroom overall as well as at each survey time except for learning strategies at Post 1. A 2 × 4 between 3 within repeated measure ANOVA determined that student MSLQ motivation and learning strategy scores in the regular classroom varied statistically significantly by teacher. Student MSLQ motivation and learning strategy scores in the life laboratory varied statistically significantly by teacher. To triangulate data, individual interviews of students were conducted at the end of the semester and revealed students regard the life laboratory as an asset to their science study; however, students do appreciate and value working in the learning environment that the regular classroom provides.     

Impact of the choice of threshold on physical activity patterns in free living conditions among adolescents measured using a uniaxial accelerometer: The HELENA study

Abstract

The aim of this study was to assess the impact of the choice of threshold on physical activity patterns measured in adolescents under free living conditions (FLC) using a uniaxial accelerometer. The study comprised 2043 adolescents (12.5–17.5 years) participating in the HELENA Study. Participants wore a uniaxial accelerometer for 7 days. The PA patterns were assessed using thresholds determined from six different studies. For each of the thresholds used, the number of adolescents fulfilling the recommendation of 60 min of moderate to vigorous PA (MVPA) per day was also calculated. A significant difference was found between thresholds regardless of the activity level: differences of 38%, 207%, 136%, and 2780% for sedentary, light, moderate, and vigorous intensity PA, respectively (P < 0.001). Time of MVPA varied between methods from 25.3 to 55.2 min · day^–1. The number of adolescents fulfilling the recommendation varied from 5.9% to 37% according to the thresholds used. The kappa coefficient for concordance in the assessment of the number of adolescents achieving the PA recommendations was generally low. The definition of the threshold for PA intensity may considerably affect the PA patterns in FLC when assessed using a uniaxial accelerometer and the number of participants fulfilling the recommendations.     

An Exploratory Analysis of the Attitudinal Impact of Awarding Athletic Scholarships to Women

The impact on women athletes of receiving or not receiving scholarships was investigated in this study. The subjects were 61 women participating in 10 intercollegiate sports. Attitudes were assessed by administering a questionnaire prior to, and after, scholarships had been awarded. The questionnaire items were grouped into three subsets which reflected different attitudes about the “impact” of awarding athletic scholarships. A 4 × 2 × 2 repeated measures design was used to test for significant statistical interaction between the three independent variables: (a) wanting a scholarship, (b) receiving a scholarship, and (c) reacting to the awarding of scholarships.     

Checking In

Despite the growing popularity of women's ice hockey in North America, players continue to face limitations because of the prohibition of body checking. In this paper, we argue from a liberal feminist philosophical perspective that this prohibition reinforces existing traditional stereotypes of female athletes. Because the women's game does not incorporate checking, female ice hockey players are not afforded the same opportunity to flourish as men and experience bodily agency, which results in continued male domination of the game, therefore, indirectly reinforcing a gender hierarchy in hockey and society.     

A Marriage of Friends or Foes? Radio,Newspapers, and the Facsimile in the 1930s

The 1930s represent a contentious period between the radio and newspaper industries. In the middle of the press-radio war, a new technology, the broadcast radio facsimile, emerged with the potential to bring together the warring industries. Although the radio facsimile was short lived, its story, seen through the lens of the press-radio war, provides an interesting look at the forces shaping a new technology.

Envisioned as a technology that would allow subscribers to receive the newspaper via a radio receiver, the facsimile presented an interesting dilemma: Who would control the creation and dissemination of news—the newspaper or radio industry? This article explores this question through an examination of industry narratives about the facsimile. In analyzing the discourses, this study focuses on how the newspaper and radio industries envisioned the future of the facsimile. Was the facsimile viewed as a means for cooperation or as a point of contention?     

The impact of a Framework‐aligned science professional development program on literacy and mathematics achievement of K‐3 students

This study investigates the effect of a Framework‐aligned professional development program at the PreK‐3 level. The NSF funded program integrated science with literacy and mathematics learning and provided teacher professional development, along with materials and programming for parents to encourage science investigations and discourse around science in the home. This quasi‐experimental study used a three‐level hierarchical linear model to compare the Renaissance STAR Early Literacy, Reading, and Mathematics scores from 2015 to 2016 of K‐3 students in treatment and control classrooms in a large Midwestern urban school district. The statistically significant results indicate that, on average, every year that a student has a program teacher adds 8.6 points to a student's spring STAR Early Literacy score, 17.0 points to a student's STAR Mathematics score, and 41.4 points to a student's STAR Reading score compared to control students. Implications for early elementary teacher education and policy are discussed. © 2017 Wiley Periodicals, Inc. J Res Sci Teach 54:1174–1196, 2017
