Reading skills are an important component of academic success for school-age youth, and are associated with increased academic performance and positive attitudes about school. The presence of an animal appears to reduce stress during reading. Therefore, the goal of this study was to assess the feasibility and effects of a 6-week after-school canine-assisted reading program in a public elementary school setting. Second-grade students were randomized to either an intervention group (n?=?14) in which they read to a registered therapy dog for 30 min once weekly for 6 weeks or a control group (n?=?14) with a standard classroom curriculum. Children’s reading skills were assessed biweekly and attitudes about reading were assessed pre- and post-intervention. The 6-week after-school canine-assisted reading program was feasible. Reading skill scores did not change significantly for either group. Although scores on recreational reading attitudes also did not change significantly for either group, the academic reading attitudes scores increased significantly in the intervention group (p?=?.002), but not in the control group (p?=?.06). These results support the benefits of an animal-assisted intervention for child literacy on children’s attitudes about reading and can inform future programs evaluating reading programs that include dogs.  相似文献

This study examined the efficacy of using different types of mobile media apps to increase the receptive and expressive vocabulary development of 3-, 4-, and 5-year-old preschool children living in economically disadvantaged communities. Children and teachers in four Head Start classrooms participated in the quasi-experimental study, which included an 8-week intervention in which the children interacted with one of two types of apps: one classroom used four scaffolding-like vocabulary apps for an average of 1.8 h per day (n?=?16) and one classroom used four open-ended vocabulary apps for an average of 1.3 h per day (n?=?15). Two classrooms served as comparison groups (n?=?18; n?=?14) which used apps that were chosen by the Head Start program with no specific instructional method for approximately 1 h per day. Children’s vocabulary was assessed pre- and post-intervention using the PPVT-4, the EVT-2, and iPad Receptive and Expressive Vocabulary Assessments. Using a repeated measures analysis of variance with split plot analysis, children who used scaffolding-like vocabulary apps performed statistically significantly higher on the PPVT-4 than children who used open-ended vocabulary apps. There were no significant differences between groups on the EVT-2. The study contributed to the literature on teacher instruction of utilizing scaffolding-like apps to increase preschool vocabulary knowledge.  相似文献

Formative assessment is considered to be a promising teaching practice for promoting teaching and learning processes. The implementation of teaching practices into instruction involves intervening with a learning environment that is characterised by certain features of instructional quality. Our study aims to contribute to the understanding of formative assessment by analysing the interplay between a formative assessment intervention and aspects of general instructional quality. In a quasi-experimental study design, 15 teachers participated in a control group (n = 361 students) and 20 teachers in the intervention classes (n = 498 students) implemented a curriculum-embedded formative assessment tool in their ninth-grade mathematics classes. No effects were found for the intervention on the assessed aspects of general instructional quality (process-oriented instruction, teacher–student relationship, effective use of instructional time). However, multilevel regression analyses revealed an interaction effect between the intervention and process-orientation and the effective use of instruction time. Our findings suggest that implementing formative assessment tools do not seem to suffice regarding changes in general instructional quality, but that an intervention with detailed material and guidelines can counterbalance effects of instructional quality, fostering students’ achievement in classes with lower degrees of process orientation and a less effective use of instructional time.  相似文献

This intervention study examines the different effects that work on video- or text-based teaching cases has on improving feedback-related performance (dependent variable) for trainee PE teachers. Within a teaching-learning arrangement, one group (n?=?24) worked with video-based teaching cases while another group (n?=?9) worked with text-based ones. In addition, both groups completed a school practicum. Additionally, a control group (n?=?23) completed the practicum, without any teaching case intervention. The quality of the feedback-related performance of the trainee PE teachers was recorded using video vignettes both before and after the respective interventions and then evaluated on the basis of an external assessment (expert rating). The results show that the work on video- and text-based teaching cases was effective, but that the videobased procedure had more of an impact, with a high level of practical significance. The control group was unable to improve on the basis of the placement within a school. The results demonstrate their usefulness for future training and competence diagnostics.  相似文献

The current intervention study investigated the sustained effectiveness of phonological awareness training on the reading development of 16 children in French immersion who were identified as at-risk readers based on grade 1 English measures. The intervention program provided children from three cohorts with supplemental reading in small groups on a withdrawal basis. Children in the experimental group (n = 5) received English phonological awareness training in combination with letter-sound correspondence instruction twice per week for 18 consecutive weeks, while those in the control condition (n = 7) engaged in English vocabulary-building activities. Significant gains were made after the training and maintained for 2 years on both French phonological awareness and French word reading skills for the experimental group. Results suggest that a phonologically based intervention in English can effectively address phonological awareness deficits and facilitate reading acquisition for French immersion children who may be at-risk for later reading difficulties.  相似文献

We conducted a meta-analysis to investigate the effectiveness of interventions aimed at reducing teacher burnout. Online and reference list searches yielded 513 unique results, and the final sample contains 23 controlled trials (19 journal articles and 4 unpublished dissertations). More than two thirds of the studies had optimal quality, and the risk of bias was not related to the overall effectiveness of the interventions. The overall effects were small, but statistically significant (d = 0.18, SE = 0.05, Z = 3.26, p < 0.001, k = 23). Separate analyses on each burnout component showed similar intervention effects on emotional exhaustion and personal accomplishment, but almost null effects on depersonalization (d = 0.03, SE = 0.06, Z = 0.53, p > 0.05, k = 11). Additional moderator analyses suggested that mindfulness interventions had significant effects on exhaustion and personal accomplishment. Interventions on primary and middle school teachers reported effect sizes below the average effect. Similar to previous findings, interventions that lasted less than 1 month had the smallest levels of efficacy.  相似文献

A total of 112 Taiwanese junior college freshmen, assigned to an experimental group (N=59) and a control group (N=62), responded to the State-Trait Anxiety Inventory. After they had participated in a career education course the experimental group scores on state anxiety decreased. An analysis of variance of the state anxiety scores yielded two main significant effects (group and trait anxiety) and a two-way interaction was found with trait anxiety and group. There was clear support for the importance of the career education course. The results and implications for continuing research are discussed.  相似文献

Increases in the number of college students seeking mental health services require counseling centers to explore innovative strategies to provide effective and efficient treatments. Group interventions offer an alternative to traditional individual counseling, allowing centers to serve more students with fewer clinical staff (Burlingame et al., 2016). Of current group modalities, mindfulness-based interventions (MBIs) have been growing in popularity as an effective approach for addressing college students’ increasingly complex needs. This study describes the evaluation of a three-session mindfulness-based intervention on students’ mindfulness, symptoms, and stress. Compared to a comparison group of 109 students not seeking counseling center services, 78 students who received the intervention reported increased mindfulness, and decreased symptoms of depression, anxiety, and stress at the end of the group. Furthermore, improvements in mindfulness mediated intervention effects on symptoms of depression and anxiety. These gains were generally maintained 3 weeks later. These findings support the benefits of brief group interventions for college students. Suggestions for modifications to the intervention and for future research are discussed.  相似文献

Studies have shown that children benefit from a spelling pronunciation strategy in remembering the spellings of words. The current study determined whether this strategy also helps adults learn to spell commonly misspelled words. Participants were native English speaking college students (N = 42), mean age 22.5 years (SD = 7.87). An experimental design with random assignment, pretests, training, and posttests assessed effects of the pronunciation strategy on memory for the spellings of 20 hard to spell words. Half of the participants were trained to read the words by assigning spelling pronunciations during learning (n = 21). The comparison group (n = 21) practiced reading the words normally without the strategy. Strategy trained adults recalled significantly more words, total letters, silent letters, and schwa vowel letters correctly than controls. Poor spellers benefited as much if not more from this strategy as good spellers. Results support orthographic mapping theories. Optimizing the match between spelling units and sound units, including graphemes and phonemes, syllables, and morphemes, to create spelling pronunciations when words are read enhances memory for spellings of the words. As a result, higher quality lexical representations are retained in memory. Results suggest the value of teaching college students this strategy to improve their ability to spell words correctly in their written work.  相似文献

As an easy application of the intermediate value theorem, one can show that for any continuous function f: [0, 1] → ? with f (0) = f (1), there are points a, a + 1/2 both in [0, 1] such that f (a) = f (a + 1/2). In this note, we show that this property holds with 1/2 replaced by any number of the form 1/n for a positive integer n. More interestingly, we show that this is false for every number not of the form 1/n.  相似文献

Perception and production of the vowels /I/, /?/, /æ/ in the words pit, pet and pat were investigated in two groups of adolescents who differed significantly on measures of reading and phonological awareness. Perception performance was assessed using slope measurements between vowel categories. Duration measurements and a rating system based on first and second formant (F1 and F2) values were used to analyze production performance. As a group, the students with reading disabilities not only perceived but also produced less well-defined vowel categories than the control group of age-matched good readers. Perception and production performance, however, were not correlated. Results suggest that the speech processing difficulties of the students with reading disabilities include weak phonological coding for vowel sounds with similar phonetic characteristics. The implications of these findings for intervention are addressed.  相似文献

Objective

Being overweight or obese comprises a significant risk factor for atherosclerosis. Fat tissue also generates factors stimulating angiogenesis, the process by which new blood vessels form. The purpose of this paper is to assess concentrations of the vascular endothelial growth factor A (VEGF-A) and its soluble type-1 and type-2 receptors (sVEGFR-1 and sVEGFR-2) in plasma of patients with peripheral arterial disease (PAD) depending on the level of nutrition according to body mass index (BMI).

Methods

The study group included patients suffering from symptomatic PAD (n=46) in Fontaine classes IIa–IV without any history of neoplastic disease and who have a normal BMI (n=15), are overweight (n=21) or are obese (n=10). The control group (n=30) consisted of healthy non-smoking volunteers who were neither overweight nor obese. Venous blood plasma samples were collected from both groups at rest in the morning to determine plasma concentrations of VEGF-A, sVEGFR-1, and sVEGFR-2 using the enzymelinked immunosorbent assay (ELISA) method.

Results

The group of patients with PAD co-existent with being overweight or obese tended to have higher mean concentration levels of VEGF-A and sVEGFR-2 when compared with patients suffering from PAD with normal BMI. A statistically significant positive correlation was obtained between BMI and average plasma concentrations of sVEGFR-2 (R=0.37, P=0.0103). However, no significant correlation was noticed between BMI and VEGF-A or sVEGFR-1 concentrations.

Conclusions

A positive correlation determined between the level of antiangiogenic factor and BMI value may be indicative of the linearly growing prevalence of some antiangiogenic factors in patients with metabolic disorders, which may be one of numerous factors contributing to incomplete efficiency of collateral circulation development in patients with PAD.

In this paper we present findings from a project that documented the development of preservice teachers’ beliefs and practices in delivering science instruction that considers issues of language and culture. Teacher candidates in the intervention group (n = 65) received a science methods course and teaching practicum experience that provided guidance in teaching science in culturally and linguistically responsive ways. Comparisons between a control group of preservice teachers (n = 45) and those involved in the intervention yielded stronger beliefs about the efficacy in promoting collaboration in science teaching than the intervention group. Observations of these preservice teachers during their teaching practicum revealed differences in favor of the intervention group in: (a) implementing science instruction that addressed the language and literacy involved in science; (b) using questions that elicited higher order thinking and; (c) providing scaffolds (e.g., purposeful feedback, probing student background knowledge) when confronting abstract scientific concepts. Implications for preservice teacher education are addressed.  相似文献

This study was designed to investigate the therapeutic approaches and prognosis for cervical cancer associated with pregnancy. Clinical information, therapeutic strategies, and follow-up results of 20 patients with cervical cancer associated with pregnancy from Jan. 2000 to June 2009 in the Zhejiang Cancer Hospital were retrospectively analyzed. The International Federation of Gynecology and Obstetrics (FIGO) stages were: in situn=1), stage IA1 n=1), stage IB1 n=5), stage IB2 n=1), stage IIA n=8), stage IIB n=3), and stage IIIB n=1). Eight patients were in the first trimester of pregnancy, four in the second, two in the third, and six at postpartum when diagnosed. The therapeutic strategies were either single or combined modalities, including surgery, radiotherapy, and chemotherapy. Fourteen patients survived, five patients died (four of remote metastasis and one of uremia), and one patient was lost to follow-up. One newborn from a patient at stage IIA carcinoma in the third trimester with postponed therapy six weeks after diagnosis survived. Retarded fetal growth was observed in one patient receiving neoadjuvant chemotherapy and cesarean section. Out of the six postpartum patients, three underwent cesarean section and survived, whereas only one out of the three who underwent vaginal delivery survived. The remaining two died of remote metastasis. Therefore, personalized treatment is necessary for cervical cancer associated with pregnancy. Cervical cancer patients in the third trimester of pregnancy can continue the pregnancy for a short period of time. There may be potential risk for the fetus by chemotherapy during pregnancy. Cesarean section is the preferred mode of delivery for pregnant cervical cancer patients.  相似文献

Evidence suggests that in the professional education of teachers the moral goals are currently a neglected topic in favor of the subject matter and knowledge. The constructivist instructional approach VaKE (Values and Knowledge Education) addresses this problem by combining the moral and epistemic goals through the discussion of moral dilemmas. The main research question of this practice-based study was whether teacher educators can improve their instructional practice by using VaKE. We describe an empirical study of a teacher educator who used VaKE in order to (i) facilitate pre-service teachers to solve moral conflicts which they are faced with in their workplace learning and to (ii) increase the moral climate in his course. 58 pre-service teachers who formed two classes participated in the study. The study consisted of three research phases: In the first research phase the types of the pre-service teachers’ moral conflicts were examined. In the second research phase the most frequent types of moral conflicts were used as a basis for an explorative quasi-experimental pre-posttest study. This study investigated the effects of VaKE compared to a traditional case-analysis approach with regard to the pre-service teachers’ application of discourse-oriented actions for conflict resolution. In the third phase, a case study method was used comprising a random sample of seven pre-service teachers chosen from each class to investigate the perceived learning climate during the intervention. The results indicate that VaKE provides the possibility to combine the moral and epistemic goals of the professional education of teachers.  相似文献

This project developed and studied The Source, an alternate reality game (ARG) designed to foster interest and knowledge related to science, technology, engineering, and math (STEM) among youth from populations underrepresented in STEM fields. ARGs are multiplayer games that engage participants across several media such as shared websites, social media, personal communications, and real-world settings to complete activities and collaborate with team members. The Source was a five-week summer program with 144 participants from Chicago aged 13 to 18 years. The Source incorporated six socio-contextual factors derived from three frameworks: Chang’s (ERIC Digest, 2002) recommendations for engaging underrepresented populations in STEM careers, Lave and Wenger’s (Cambridge University Press, 1991) situated learning model, and Barron’s (Human Development, 49(4); 193-224, 2006) learning ecology perspective. These factors aligned with the program’s aims of promoting (1) social community and peer support, (2) collaboration and teamwork, (3) real-world relevance and investigative learning, (4) mentoring and exposure to STEM professionals, (5) hands-on activities to foster transferable skill building, and (6) interface with technology. This paper presents results from 10 focus groups and 10 individual interviews conducted with a subset of the 144 youth participants who completed the game. It describes how these six factors were realized through The Source and uses them as a lens for considering how The Source functioned pedagogically. Qualitative findings describe youth’s perception of The Source’s potential influence on STEM interest, engagement, and identity formation. Despite limitations, study results indicate that underrepresented youth can engage in an immersive, narrative, and game-based experience as a potential mechanism for piquing and developing STEM interest and skills, particularly among underrepresented youth.  相似文献

This study sought to understand predictors of faculty satisfaction with promotion and tenure processes and reasonableness of expectations in the context of a striving institution. The factors we investigated included discipline (high-consensus [science and math] vs. low-consensus [humanities and social sciences]); demographic variables; and institutional support including mentoring, collegiality, work-life integration, and college commitment to faculty members’ fields. High-consensus faculty members were less satisfied with promotion and tenure processes than were low-consensus faculty members (p?<?.01). Faculty members who were more satisfied with collegiality (p?<?.001) and with college commitment to their fields (p?<?.05) were more satisfied with promotion and tenure processes. Faculty members who were more satisfied with work-life integration and mentoring were more satisfied with reasonableness of expectations (p?<?.05).  相似文献

Chemistry knowledge can be represented at macro-, micro- and symbolic levels, and learning a chemistry topic requires students to engage in multiple representational activities. This study focused on scaffolding for inter-level connection-making in learning chemistry knowledge with graphical simulations. We also tested whether different sequences of representational activities produced different student learning outcomes in learning a chemistry topic. A sample of 129 seventh graders participated in this study. In a simulation-based environment, participants completed three representational activities to learn several ideal gas law concepts. We conducted a 2 × 3 factorial design experiment. We compared two scaffolding conditions: (1) the inter-level scaffolding condition in which participants received inter-level questions and experienced the dynamic link function in the simulation-based environment and (2) the intra-level scaffolding condition in which participants received intra-level questions and did not experience the dynamic link function. We also compared three different sequences of representational activities: macro-symbolic-micro, micro-symbolic-macro and symbolic-micro-macro. For the scaffolding variable, we found that the inter-level scaffolding condition produced significantly better performance in both knowledge comprehension and application, compared to the intra-level scaffolding condition. For the sequence variable, we found that the macro-symbolic-micro sequence produced significantly better knowledge comprehension performance than the other two sequences; however, it did not benefit knowledge application performance. There was a trend that the treatment group who experienced inter-level scaffolding and the micro-symbolic-macro sequence achieved the best knowledge application performance.  相似文献
