The authors propose the Interactive Training Model (ITM), a full classroom role play experience, as a method for helping student counselors develop essential interviewing and counseling skills and self‐awareness as required by the 2009 Council for Accreditation of Counseling and Related Educational Programs Standards. This pre‐post, quasiexperimental study involving 45 master's‐level students indicated that those who participated in the ITM made greater gains in supervisee development compared with those who participated in a traditional peer feedback model. Narrative student feedback regarding the use of ITM in an essential skills course is presented, and implications for counselor education are discussed.  相似文献

The development of interest in reading and its relationship to reading ability was examined longitudinally in 117 children in Grades 1–3. Interest in reading was measured by eight items from the Elementary Reading Attitude Survey. Less able readers had lower interest in reading, but their development was parallel to that of more able readers. Interest in reading in Grade 1 was weakly correlated with Grade 3 reading ability, but correlations were lower for interest measured in Grades 2 and 3. Hierarchical regression analyses indicated weak and inconsistent effects of reading interest on reading ability after controlling general cognitive ability, SES, phonological awareness and naming speed. It is concluded that interest in reading has only a weak relationship to reading ability in the early elementary years, and that much of that relationship overlaps with the effects of other more powerful predictors.  相似文献

This paper presents a novel sensor technology to deduce the dynamics of a bowling ball. The sensor, a miniature wireless inertial measurement unit (IMU), incorporates MEMS accelerometers and angular rate gyros, a microcontroller, a low power RF transceiver, and a rechargeable battery. When embedded in a bowling ball, the IMU transmits the acceleration and angular velocity data that define the dynamics of the ball starting with the bowler’s delivery and its motion in the lane. Example results from professional bowlers illustrate how this technology can be used to assess bowler skill and ball performance. For instance, the IMU accurately measures the spin dynamics of the ball which are crucial to develop the ball “hook.” An analysis of ball dynamics in the lane is distilled to a measurable “hook potential” metric for further assessing bowler skill. Finally, the sensor presented herein is believed to be the world’s smallest, wireless IMU. This highly miniaturized and wireless design will enable parallel training systems for many sports, including basketball, baseball, crew, cricket, golf, fly fishing, soccer, softball, tennis, rowing, among others.  相似文献

Incidents become crises through a constant and intense public scrutiny facilitated by the media. Two incidents involving dioxin contamination of food led to crises in Belgium and the Republic of Ireland in 1999 and 2008, respectively. Thought to cause cancer in humans, dioxins reached the food supply in both incidents through the contamination of fat used for animal feed. The food and agricultural industries connected to each incident relied on crisis management activities of federal governments to limit adverse public reaction. Analysis of the management of the two crises by their respective federal governments, and a subsequent review of crisis management literature, led to the development of an effective crisis management model. Such a model, appropriately employed, may insulate industries associated with a crisis against damaged reputations and financial loss.  相似文献

International students continue to grow in number worldwide, prompting researchers to look for ways to make the study abroad experience more fruitful. One avenue of research has focused on friendship formation, the significant role it plays in the study abroad experience, and the unique friendship combinations made possible by the study abroad experience. International students form friendships with individuals from their own country, from other countries, and from the host country. Research has found that international students often have more friends from their home country; however, research has also demonstrated a relationship between having more host country friends and satisfaction, contentment, decreased homesickness, and social connectedness. The current study looks to further explore these relationships through a social network lens by examining friendship network ratios, strength, and variability of the three friendship groups. A friendship network grid was developed to assess where international students’ friends are from and how strong those friendships are. Eighty four international students completed a survey examining the relationship between friendship networks, social connectedness, homesickness, contentment, and satisfaction. Contrary to prior research, international students did not report having a higher ratio of individuals from their home country in their friendship networks. However, international students with a higher ratio of individuals from the host country in their network claimed to be more satisfied, content, and less homesick. Furthermore, participants who reported more friendship variability with host country individuals described themselves as more satisfied, content, and more socially connected. Implications and directions for future research are discussed.  相似文献

The aim of this study was to understand adolescent mothers’ childbirth experiences. Semistructured interviews were conducted with participants recruited from a community-based program for adolescent mothers. Fourteen mothers described their birth experiences. Using a narrative analytic approach, responses were reconstructed into birth stories. Stories, condensed into poetic form, were compared and contrasted. Four unique categories emerged: connected births, surreal births, disconnected births, and disempowered births. Categories differed by agency, support, and emotional tone. Positive support was found in stories that portrayed high agency and positive affect, whereas problematic support was apparent in stories that conveyed passivity, frustration, and disappointment. This study has implications for tailoring childbirth education for adolescent mothers and can inform health-care professionals working with this population.  相似文献

It is argued that online discussion is a useful tool for creating opportunities for learning in teacher education. In a project designed to improve the practicum in rural areas, researchers placed pre-service teachers (PSTs) in two different moderated online discussion forums: an unstructured personal blog space and a structured threaded discussion forum where discussion topics guided them to reflect on their practicum experiences in relation to theoretical components of their studies. Findings indicated a marked difference in the contributions made to each form of online discussion with significantly greater participation in the unstructured blog format. Using Kreber and Cranton’s hierarchy of reflection, analyses of both forums found that PSTs rarely engaged in high-level reflection. Examination of lecturer involvement in the forums suggests that their contributions did not sufficiently encourage PSTs towards optimum critical reflection. These results leave the researchers considering ways in which the practicum experience can better promote reflective practice in this crucial, component of teacher education.  相似文献

The majority of eukaryotic genes produce multiple mRNA isoforms with distinct 3′ ends through a process called mRNA alternative polyadenylation (APA). Recent studies have demonstrated that APA is dynamically regulated during development and in response to environmental stimuli. A number of mechanisms have been described for APA regulation. In this review, we attempt to integrate all the known mechanisms into a unified model. This model not only explains most of previous results, but also provides testable predictions that will improve our understanding of the mechanistic details of APA regulation. Finally, we briefly discuss the known and putative functions of APA regulation.  相似文献

This study was designed to (a) test the psychometric properties of a new observation measure of developmentally appropriate classroom practices in kindergarten through third-grade classrooms, and (b) determine how well classroom and teacher characteristics predict developmentally appropriate classroom practices. Teacher-reported and observational data from 69 classrooms provided support for construct validity, internal consistency, and interrater agreement of the Assessment of Practices in Early Elementary Classrooms (APEEC) measure. Hierarchical multiple regression analyses indicated that classroom characteristics (grade, class size, number of children with disabilities), teacher characteristics (education level, years of experience) and teacher beliefs (developmentally appropriate beliefs and developmentally inappropriate beliefs) accounted for 42% of the variance in observed classroom practices. With all variables in the model, teacher education, grade, and beliefs in developmentally appropriate and inappropriate practice accounted for most of the variance in observed classroom practices.  相似文献
