Research on understanding the full extent that an authentic science research experience engages students in how scientists think and act is sparse. ‘Learning-science-by-doing-science’ (LSDS) is an emerging self-guided process-learning model in postsecondary science education. It offers authentic science research opportunities that drive students to think and act like scientists. This study investigates the LSDS approach as a potential model for science learning at postsecondary level and aims to answer a main research inquiry – what are the students’ and teaching staff’s perceptions of students’ learning gains and the quality of their learning experiences in an authentic research environment within the LSDS model? To answer this question, data were collected from the students, alumni, instructors, teaching assistants and the program director via questionnaires, focus groups and interviews. Students’ and staff’s lived experiences and their perceptions on their authentic research experiences within the LSDS model were used to articulate the key attributes and stages of the LSDS model. The outcomes of this study can be used to help other science programs implement similar authentic research process learning approaches in their own contexts.  相似文献   

Macrostructure construction and organization in the processing of multiple text passages     

Natasha Lacroix 《Instructional Science》1999,27(3-4):221-233

This paper addresses the issue of macrostructural processing of multiple text passages. Two levels of macrostructural processing, macrostructural construction (extracting important information) and organization (structuring selected information) may be at work during complex text comprehension. Three experiments examined the effects of various textual and situational factors on macrostructural construction and organization. College students were asked to read small sets of documents presented in hypertext format. The students' reading strategies as well as their written reports were analyzed. Experiment 1 showed that headings and presentation format influence macrostructural organization. Experiment 2 showed that task requirements tend to influence macrostructure construction and organization, whereas presentation conditions, such as the marking of important information and the presentation order, can affect both levels of macrostructural processing. Finally, experiment 3 indicated that there is an interaction between global and local headings and the construction and organization of macrostructure. The three experiments also suggested that subjects can be characterized based on how well they deal with macrostructural construction and organization. It is concluded that the comprehension of hypertext involves higher levels of cognitive processing which ensure the structuring of multiple text information.  相似文献   

Cognitive Stimulation at Home and in Child Care and Children’s Preacademic Skills in Two-Parent Families     

Natasha J. Cabrera  Ui Jeong Moon  Jay Fagan  Jerry West  Daniela Aldoney 《Child development》2020,91(5):1709-1717

This paper used the Early Childhood Longitudinal Study-Birth Cohort (N = 1,258) to examine the influence of hilevels of cognitive stimulation from mothers, fathers, and childcare providers at 24 months and children’s pre-academic skills at 48 and 60 months in two parent families. Results from path analysis showed direct positive effects of fathers’ early cognitive stimulation on early reading and math skills at 48 and 60 months. There were also two moderated effects: The effects of high levels of maternal stimulation at 24 months on early math and reading skills at 48 months were largest for children also receiving high levels of cognitive stimulation from their childcare providers. Implications for including fathers in studies of the home cognitive stimulation and strengthening the parent-childcare connection are discussed.  相似文献   

Innovative Practice: Sister‐Friends: A Counseling Group for Black Female Undergraduates     

Natasha A. Mitchell 《Journal of College Counseling》2000,3(1):73-77

Sister‐Friends, a counseling group for Black female undergraduate students, was implemented to help Black female students cope with isolation at a predominantly White university. This group seemed to help members reduce their feelings of isolation and to persist with academic studies during the semester.  相似文献   

The feasibility of fundamental movement skill assessments for pre-school aged children     

Brooke Klingberg  Natasha Schranz  Lisa M. Barnett  Verity Booth  Katia Ferrar 《Journal of sports sciences》2019,37(4):378-386

Fundamental movement skill (FMS) assessment in preschools allows for early intervention; however it is unclear what assessments are feasible. The purpose of this review is to systematically review the feasibility of FMS assessments for pre-school aged children. The search was conducted across four databases, MEDLINE, Scopus, ERIC and SportsDiscus. Search terms included synonyms of “fundamental movement skills” and “pre-school children”. Inclusion criteria were: (i) FMS assessment; (ii) feasibility data; (iii) assessment of children aged three to six years; (iv) assessment of typically developing children; and (v) peer reviewed full text publications in English. Feasibility concepts (administration time, equipment, space, assessment type, item, training, qualification) were each coded as ‘poor = 1?, ‘average = 2? and ‘good = 3?; potential total of 21. A total of 330 full text articles were considered but a quarter (n = 86) were excluded due to no feasibility data. Sixty-five studies using 13 different FMS assessments were included. The Athletic Skills Track and DEMOST-PRE assessments were most feasible (18/21) and the Test of Gross Motor Development and Movement Assessment Battery for Children were common but among the least feasible (12–14/21). This review allows pre-school staff to choose a FMS assessment based on feasibility. Future studies need to present feasibility of assessments.  相似文献   

Physical,physiological, and technical demands of national netball umpires at different competition levels     

Kirsten Spencer  Natasha Paget  Andrew Kilding 《Journal of sports sciences》2020,38(14):1660-1665

ABSTRACT

To compare demands of national netball umpires between levels of competition, 22 Netball New Zealand high-performance umpires participated in this investigation. These included from highest to lowest standard: 9 × semi-professional ANZ Championships (ANZC); 6 × National A Squad (NZA); and 7 × National Development Squad (DEV). Physical (global positioning system tri-axial accelerometry), physiological (heart rate) and technical (video analysis) demands were determined for 48 (16 per group) umpire match performances. Level of competition had no significant effect on physical or mean physiological demands. However, ANZC umpires spent a lower proportion of time at low heart rates compared to DEV, and a greater proportion of time at high, rather than moderate, heart rates compared to NZA. Compared to lower standard umpires, ANZC spent lesser proportions of time standing but greater proportions of time walking backwards and sideways, and turning to change direction. Furthermore, ANZC umpires spent lower proportions of time jogging, but greater proportions of time sprinting compared to DEV. Finally, ANZC umpires spent longer mean durations than DEV on the goal third side line. As such, the difference in demands experienced by national netball umpires between levels of competition is more technical than physical or physiological.  相似文献
