Environmental literacy and nature experience in Chengdu,China

Abstract

This research investigated environmental literacy and nature experience among 1433 children and adults in Chengdu, China. Utilizing a standard measure of environmental literacy modified to be culture- and age-appropriate, we found almost universal agreement that nature should be protected. Although our results showed that older groups were less likely to enjoy experiences in nature compared to the younger ones, this was not reflected in a reduced appreciation for nature, which was high in all age groups. Within each category of student, age was associated with increased knowledge but decreased enjoyment of nature experiences and environmental concern. In contrast, among the adult residents, increasing age was associated with less objective knowledge but with more liking and concern about nature. Based on these results, we provide recommendations for environmental education that incorporates time in nature in order to foster environmental concern and behavior as well as knowledge.     

Information seeking,technology use,and vulnerability among migrants at the United States–Mexico border

Through interviews with migrants and migrant aid-workers at a shelter in the border town of Nogales, Mexico, we examine how undocumented migrants are seeking, acquiring, understanding, and using information prior to, and during, migration across the United States–Mexico border. Our study examines migrants' perceptions of humanitarian service and the use of so-called “border disturbance technologies” by activists to help prevent the death of migrants in the desert, finding that migrants appreciate water-caching efforts but generally distrust technologies they feel could subject them to surveillance by border agents. Exploratory in nature and based on a small sample, our findings are not necessarily representative of the broader population, but provide rich evidence of the prevalence of word-of-mouth information seeking and use of cell phones over other information technologies, and explore the ambivalent nature of information technology use in the vulnerable setting of life at the border. In particular, we find that mobile phones help migrants meet their communication needs, but also increase their exposure to crime and abuse.     

Bringing Science to Life Through Community-Based Watershed Education

Four elements of successful student-scientist partnerships (SSPs) have been identified through experience in a wide variety of educational settings. SSPs should: use an inquiry-based approach to education; be built around authentic, community-based investigations; let students be scientists; and allow scientists to be educators. Each element is discussed and illuminated with examples from case studies of watershed education programs that are based on an interdisciplinary, action-oriented watershed education model developed by the Global Rivers Environmental Education Network (GREEN).     

The influence of hip mobility and quadriceps fatigue on sagittal spinal posture and muscle activation in rugby scrum performance

Rugby Union scrumming puts the spine under a high degree of loading. The aim of the current study was to determine how sagittal hip range of motion and quadriceps fatigue influence force output, spinal posture, and activation of the trunk and quadriceps muscles in rugby scrumming. Measures of sagittal hip flexion/extension range of motion were collected from 16 male varsity and club first XV level participants. Sagittal spine motion (electromagnetic motion capture), trunk and quadriceps activation (electromyography), and applied horizontal compressive force (force plate) were measured during individual machine scrumming. Participants performed a 5-trial scrum block involving 5?s of contact with 1–2?min recovery between each trial. They then performed a fatiguing protocol (wall sit to failure) and immediately returned to the scrum machine to perform another five trials. Though there was no significant influence of fatigue on the horizontal compressive force applied during contact (P?=?.83), there was a 52% increase in cervical flexion (P?P?P?相似文献   

Multidimensional joint coupling: a case study visualisation approach to movement coordination and variability

Abstract

A case study visualisation approach to examining the coordination and variability of multiple interacting segments is presented using a whole-body gymnastic skill as the task example. One elite male gymnast performed 10 trials of 10 longswings whilst three-dimensional locations of joint centres were tracked using a motion analysis system. Segment angles were used to define coupling between the arms and trunk, trunk and thighs and thighs and shanks. Rectified continuous relative phase profiles for each interacting couple for 80 longswings were produced. Graphical representations of coordination couplings are presented that include the traditional single coupling, followed by the relational dynamics of two couplings and finally three couplings simultaneously plotted. This method highlights the power of visualisation of movement dynamics and identifies properties of the global interacting segmental couplings that a more formal analysis may not reveal. Visualisation precedes and informs the appropriate qualitative and quantitative analysis of the dynamics.     

Social‐Cognitive Development,Ethical and Legal Knowledge,and Ethical Decision Making of Counselor Education Students

Counselors are required to have high levels of social‐cognitive development, significant knowledge regarding ethical and legal practice, and sound ethical decision‐making processes to provide effective and ethical services to their clients. This study investigated the effect of two counseling ethics courses on 64 master's‐level counselor education students' levels of social‐cognitive development, ethical and legal knowledge, and ethical decision making. Students' ethical and legal knowledge scores increased significantly, and precourse social‐cognitive maturity predicted postcourse ethical and legal knowledge scores. Implications for counselor education and development are discussed.     

USING ITEM RESPONSE THEORY TO CONDUCT A DISTRACTER ANALYSIS ON CONCEPTUAL INVENTORY OF NATURAL SELECTION

Concept inventories are often used to assess current student understanding although conceptual change models are problematic. Due to controversies with conceptual change models and the realities of student assessment, it is important that concept inventories are evaluated using a variety of theoretical models to improve quality. This study used a modified item response theory model to determine university nonmajor biology students’ levels of understanding of natural selection (n = 1,192). Using Conceptual Inventory of Natural Selection, we have reported how we applied Bock’s modified nominal item response theory model and the distracter test item analysis. We found that the use of this model can define student levels of understanding and identify problematic distracters.     

Dimensions of hope in adolescence: Relations to academic functioning and well-being

Hope—a multidimensional positive motivational state—is particularly salient with adolescents in the school setting. Cognitive hope focuses on goal attainment cognitions whereas behavioral hope focuses on actions required for goal attainment. Studies rarely examine the contribution of each type of hope to adolescents’ academic functioning and well-being. The present study examines the contributions of cognitive and behavioral hope to academic functioning (i.e., achievement and school engagement) and well-being (i.e., stress and anxiousness) across adolescence among 5th- through 12th-grade students (n = 643). When modeled concurrently, cognitive hope significantly predicted achievement, school engagement, anxiousness, and stress (high school only); however, aspects of behavioral hope only predicted school engagement. Findings provide evidence regarding the unique contribution of both types of hope in school settings and possible areas for intervention to foster hope in developmentally appropriate ways, depending on the age of the students and outcomes of interest.
