This article reports the design of a prototype for a teaching portfolio for development and assessment purposes. A portfolio prototype was developed according to theoretical choices based on portfolio literature and Zeichner and Wray's (2001) conceptual framework. We conducted an interview study in which portfolio experts were asked to judge to what extent our theoretical choices were reflected in the prototype developed and which modifications were needed. In general, the experts agreed that our choices were reflected in the prototype developed. However, there were some controversial topics, which are discussed, as well as key issues for further research.  相似文献

Older student reading of informational texts like those found in most high school classrooms continue to be a concern. College entrance exams scores attest to the fact that this age group of readers remain largely unprepared for the rigorous, discipline area reading and comprehension demands of higher education. In response to this issue content area teachers have been encouraged to teach reading skills for their subject matter. Standard reading instruction tools have included reading guides and summative reading assessments. This study sought to compare the effects of standard reading pedagogy with computerized, formative reading assessments given to students as they read. The largest publisher of high school textbooks, Pearson Prentice-Hall, and the publisher of the high school government text used in this study currently does not have in place digital, formative reading assessments tracking section by chapter section. High school seniors in nine sections of American Government under two different instructors participated in this mixed method, quasiexperimental study. Results indicate a significant difference in content comprehension with the formative assessment pedagogy. Survey and questionnaire responses suggest students thought they read better and were more motivated to read responding to computerized formative assessments (CBA’s) that closely tracked their subject matter textbooks.  相似文献

Background: The physical education (PE) context has been emphasised as an ideal environment for developing positive behaviours among students. Under the Positive Youth Development paradigm, various initiatives have been conducted with the aim of promoting personal and social responsibility among adolescents. Self-Determination Theory has been widely used to analyse students’ motivational processes during PE classes.

Purpose: This study aimed to measure the effects of a multidisciplinary intervention with teachers on the development of positive behaviours in PE classes.

Participants: Twenty PE teachers participated in the study (Mage?=?35 years; SD?=?2.32) along with 777 of their students (Mage?=?12.81 years; SD?=?.93). The teachers (male?=?16; female?=?4) were between the ages of 29 and 48 years (M?=?35.2 years; SD?=?2.32). The students who participated in this study (male?=?377; female?=?400) were divided into 52 classes and were between the ages of 12 and 16 years (M?=?12.81; SD?=?.93).

Research design: A quasi-experimental design was used that consisted of a control group and three groups in which an intervention was developed. In the control group, the teachers did not receive any type of intervention; in the second group, the teachers received a training programme to develop strategies for supporting basic psychological needs and promoting positive behaviours; in the third group, the teachers received a didactic unit to promote positive behaviours; and in the last group the teachers received a combination of the two previous interventions.

Data analysis: A repeated-measures ANCOVA (analysis of covariance) was used for every dependent variable included in the study to analyse the effect of Group?×?Time interaction, including Gender and Grade Level as covariates. The fixed effects caused by Intercept, Group, Time, and the Group?×?Time interaction were calculated using compound symmetry as the type of covariance and restricted maximum likelihood as the estimation method.

Findings: By examining the differences between pre-test and post-test, it was determined that in comparison with the students in the control group, the students from the three experimental groups had generally improved scores on the variables related to positive behaviours, such as perceptions of the teacher's support, as well as the development of the targeted behaviours.

Conclusions: These results provide information about the efficacy of an intervention programme with teachers that consists of strategies for developing positive behaviour and support for basic psychological needs to promote the development of positive student behaviour.  相似文献

Abstract

The first Asian Lesbian Film and Video Festival, held in Taipei in August 2005, brought forth media art, social activism and cultural exchange on one occasion. It provided a rare opportunity to showcase the experience of Asian lesbians, which is vastly different from the experience of those in Western countries. While there were great similarities in their love experiences among the 36 Asian lesbian shorts selected, they also reflected the differences among the Asian countries in terms of local development of tongzhi culture and community as well as the visibility of tongzhis. Among the Chinese communities, Taiwan was seen to be at the forefront of the development of tongzhi culture, Mainland China was new to the movement, and Hong Kong was somewhere in‐between. Japanese and Korean videos took a critical and reflective attitude towards social regulations and mainstream thoughts, although witty and farcical at times. While the Filipinos show a more tolerant attitude to the Lesbian Gay Bisexual Transgender (LGBT) community, the major oppressive forces on lesbians were poverty, gender inequality and sexual violence. Only one Israeli documentary was shown at the film festival, which focused on lesbians living in the Jewish Orthodox traditions. The film won international acclaim and attracted much public attention to the issue. Films and videos were found to be an effective means to transcend language barriers and cultural differences for a true cross‐cultural exchange among Asian lesbians. During the few days of festival, a ‘queer nation’, not defined by nationalities or languages, but by the pursuit of love expressions, was constructed around The Taipei House.  相似文献

The aim of this study was to investigate the effectiveness of a caffeine-containing energy drink to enhance physical and match performance in elite badminton players. Sixteen male and elite badminton players (25.4 ± 7.3 year; 71.8 ± 7.9 kg) participated in a double-blind, placebo-controlled and randomised experiment. On two different sessions, badminton players ingested 3 mg of caffeine per kg of body mass in the form of an energy drink or the same drink without caffeine (placebo). After 60 min, participants performed the following tests: handgrip maximal force production, smash jump without and with shuttlecock, squat jump, countermovement jump and the agility T-test. Later, a 45-min simulated badminton match was played. Players’ number of impacts and heart rate was measured during the match. The ingestion of the caffeinated energy drink increased squat jump height (34.5 ± 4.7 vs. 36.4 ± 4.3 cm; < 0.05), squat jump peak power (< 0.05), countermovement jump height (37.7 ± 4.5 vs. 39.5 ± 5.1 cm; < 0.05) and countermovement jump peak power (< 0.05). In addition, an increased number of total impacts was found during the badminton match (7395 ± 1594 vs. 7707 ± 2033 impacts; < 0.05). In conclusion, the results show that the use of caffeine-containing energy drink may be an effective nutritional aid to increase jump performance and activity patterns during game in elite badminton players.  相似文献

We present a control theory analysis of adolescents' attachment strategies in the Adult Attachment Interview (AAI). In Study 1, Q-sort prototypes for secure/anxious and deactivating/hyperactivating strategies were used to differentiate between Main and Goldwyn's AAI classifications. In Study 2, we examined how AAI strategies were associated with emotion regulation during mother-teen problem solving. 4 aspects of mother-teen problem solving (dysfunctional anger, support/validation, avoidance of problem solving, and maternal dominance) were used to predict teens' AAI strategies. Teens with secure strategies engaged in problem-solving discussions characterized by less dysfunctional anger and less avoidance of problem solving. In addition, attachment security showed a curvilinear relation with maternal dominance, indicating that secure teens maintained balanced assertiveness with their mothers. Teens with deactivating strategies engaged in problem-solving interactions characterized by higher levels of maternal dominance and dysfunctional anger. The contribution of attachment strategies to teens' autonomy and to transformations in mother-teen relationships is discussed.  相似文献

Introduction:

Zonulin is a eukaryotic protein structurally similar to Vibrio cholerae’s zonula occludens toxin. It plays an important role in the opening of small intestine tight junctions. The loss of gut wall integrity during sepsis might be pivotal and has been described in various experimental as well as human studies. Increased levels of zonulin could be demonstrated in diseases associated with increased intestinal inflammation, such as celiac disease and type 1 diabetes. We therefore investigated the role of plasma levels of zonulin in patients with sepsis as a non-invasive marker of gut wall integrity.

Materials and methods:

Plasma level of zonulin was measured in 25 patients with sepsis, severe sepsis or septic shock according to ACCP/SCCM criteria at the first day of diagnosed sepsis. 18 non-septic post-surgical ICU-patients and 20 healthy volunteers served as control. Plasma levels were determined by using commercially available ELISA kit. Data are given as median and interquartile range (IQR).

Results:

Significantly higher plasma concentration of zonulin were found in the sepsis group: 6.61 ng/mL (IQR 3.51–9.46), as compared to the to the post-surgical control group: 3.40 ng/mL (IQR 2.14–5.70) (P = 0.025), as well as to the healthy group: 3.55 ng/mL (IQR 3.14–4.14) (P = 0.008).

Conclusion:

We were able demonstrate elevated levels of plasma zonulin, a potential marker of intestinal permeability in septic patients. Increased zonulin may serve as an additional mechanism for the observed increased intestinal permeability during sepsis and SIRS.  相似文献
