Learning to play: A review and theoretical investigation of the developmental mechanisms and functions of cetacean play     

Heather M. Hill  Sarah Dietrich  Briana Cappiello 《Learning & behavior》2017,45(4):335-354

Play is a behavioral phenomenon most commonly observed in the young of both solitary and social species. Documentation of play in cetaceans varies across species and settings. Cetacean play behavioral repertoires include a broad range of actions, such as the manipulation of diverse objects, blowing bubbles, chasing conspecifics, and swimming in spirals through the water. As is common in research on animal play, cetacean play has been grouped into categories by its form, including locomotor play, object play, and different variations of social play, such as affiliative games, play fighting, and socio-sexual play. Research has primarily focused on recording the topography of cetacean play and the demographics of the individuals engaging in play. However, these classifications are insufficient to address the possible developmental and societal functions of cetacean play behaviors, or the mechanisms with which play behaviors are spread between conspecifics and acquired by young members of cetacean populations. This article applies several developmental and social learning theories in order to organize current knowledge and guide future research.  相似文献   

The Impact of a Professional Development Program on Teachers' Mathematical Knowledge for Teaching,Instruction, and Student Achievement     

Robin Jacob  Heather Hill  Doug Corey 《Journal of research on educational effectiveness》2017,10(2):379-407

In this paper, we describe findings from a three-year evaluation of a well-developed mathematics professional development program that is commercially available on a wide scale. The professional development is designed to improve teachers' mathematical knowledge for teaching and to enable them to elicit more student thinking and reasoning during mathematics lessons. Specifically, it focused on helping teachers (a) learn more mathematics, (b) understand how children learn math, (c) use formative assessment to develop insight into what specific students know and do not know, and (d) develop effective classroom instructional strategies that enable student problem solving. Participants included 105 fourth- and fifth-grade teachers teaching in 19 low-income schools within a single district. Teachers were randomly assigned within schools either to a “business as usual” control group or to receive the professional development. The training consisted of a week-long summer institute and four to six in-service days during the school year. The training was run by full-time trained associates. We find some limited evidence of positive impacts on teachers' mathematical knowledge for teaching, but no effects on instructional practice or student outcomes.  相似文献   

The effects of syllable instruction on phonemic awareness in preschoolers     

Teresa A. Ukrainetz  Janae J. NusplKimberly Wilkerson  Sarah Rose Beddes 《Early childhood research quarterly》2011,26(1):50

Purpose

Preschooler instruction for speech sound awareness typically teaches a progression of speech units from sentences to phonemes, ending at simple first phoneme activities. This study investigates the effects of teaching advanced tasks of phoneme blending and segmenting with and without the larger speech unit of the syllable.

Method

Thirty-nine 4-5-year-old typically developing children received twice-weekly small-group instruction in three conditions: two weeks of syllable tasks then four weeks of multiple phoneme tasks (SP), four weeks of multiple phoneme tasks only (MP), or an active control condition of first phoneme instruction (FP).

Results

The conditions SP and MP showed large significant gains on blending and segmenting and no significant differences on first phoneme isolating compared to the FP condition. A comparison of SP and MP did not show significant differences on phoneme blending and segmenting, but SP showed significantly more confusion during early sessions of phoneme instruction.

Conclusion

This preliminary evidence suggests that preschoolers can improve understanding of phoneme blending and segmenting, without first being taught syllable blending and segmenting, and with no negative effects on first sound awareness. These findings support a more efficient way of teaching preschoolers awareness of the individual sounds of speech. Replication with a larger sample, including children at-risk for literacy difficulties, is recommended before firm conclusions should be drawn.  相似文献   

Advancing Diversity in STEM     

Paul L. Hill  Rose A. Shaw  Jan R. Taylor  Brittan L. Hallar 《Innovative Higher Education》2011,36(1):19-27

Although progress has been made, greater efforts are needed to promote faculty diversity at the college and university levels, especially in STEM fields. Thus, it is important to elucidate best practices both for increasing awareness of diversity issues pertaining to higher education and for implementing change. This article focuses on the outcomes of a diversity workshop for college and university faculty hosted by the West Virginia Higher Education Policy Commission, Division of Science and Research. More specifically, it elucidates how participation in the workshop translated into practice at the faculty participants’ home institutions.  相似文献

Reporting Mobile Social Media Use: How Survey and Experience Sampling Measures Differ     

Teresa K. Naab  Veronika Karnowski  Daniela Schlütz 《Communication methods and measures》2019,13(2):126-147

Quantifying the ubiquitous, ephemeral, and highly diverse patterns of mobile social media (MSM) use is a challenge for communication research. Most researchers employ retrospective survey measurement, thus depending on the accuracy of users’ memories and generalizations. Alternatively, some researchers rely on in-situ measurement, being less dependent on users’ memories and generalizations, but requiring random situation samples. To assess differences and similarities between these two measurement approaches we analyzed whether characteristics (duration and frequency of a usage episode, habit, elaboration, and gratifications) of MSM use (regarding Facebook, WhatsApp, and YouTube) vary between retrospective survey and mobile experience sampling measurement. We observe a consistent pattern of higher estimates in retrospect as compared to individual averages of in-situ reports. The absolute magnitude of these differences varies considerably between platforms and characteristics studied. Nonetheless, for most constructs and platforms we find low significant positive correlations between retrospective and aggregated in-situ values.  相似文献   

Examining the influence of the parent-initiated and coach-created motivational climates upon athletes' perfectionistic cognitions     

Appleton PR  Hall HK  Hill AP 《Journal of sports sciences》2011,29(7):661-671

The aims of this study are threefold. First, we investigate the influence of the parent-initiated motivational climate upon elite junior athletes' perfectionistic cognitions. Second, we examine whether the coach-created motivational climate predicts additional variance in elite junior athletes' perfectionistic cognitions beyond the effects associated with the parent-initiated motivational climate. Third, we test the moderating role of athletes' gender and age in the relationship between the parent-initiated and coach-created motivational climates and athletes' perfectionistic cognitions. A total of 190 elite junior athletes (mean age 15.2 years, s?=?1.5, range 10-18) completed the Parent-Initiated Motivational Climate Questionnaire-2 (White & Duda, 1993), the Perceived Motivational Climate in Sport Questionnaire-2 (Newton, Duda, & Yin, 2000), and the Perfectionistic Cognitions Inventory (Flett, Hewitt, Blankstein, & Gray, 1998). Regression analyses revealed that mother- and father-initiated worry-conducive climates, the father-initiated success-without-effort climate, and the coach-created performance motivational climate predicted male athletes' perfectionistic cognitions. Female athletes' perfectionistic cognitions were predicted by the mother-initiated worry-conducive climate, father-initiated learning-enjoyment climate, and both dimensions of the coach-created climate. Finally, athletes' gender emerged as a significant moderator of the mother-initiated worry-conducive climate and athletes' perfectionistic cognitions relationship. Findings confirm that the parent-initiated motivational climate is a significant predictor of athletes' perfectionism-related thoughts, and provide initial support for the influence of the coach-created motivation climate over children's perfectionistic cognitions.  相似文献
