Pre-service Teachers: Reflections on Observed Practice

Reflective practice serves as a powerful pedagogical strategy for teachers—especially those in low-resource, rural areas. This qualitative case study looked at secondary education pre-service teachers in their first education course. Analysis of focus observation essays data indicated that pre-service teachers were incorporating reflective practice in their field observations, but were not addressing issues of diversity – specifically race and socio-economic status. This study is significant for understanding how pre-service teachers engage in reflective practices with respect to diversity

Community Engagement through Interactive Field-Based Activities

This qualitative case study consisted of social justice interactive field-based experiential learning activities designed to understand community partnerships between a university and local public school. The research question was: How can interactive field-based activities build closer community ties? The theoretical foundation incorporated Ken Zeichner’s “hybrid spaces” with the premise of field-based interactive experiences. The findings indicated the need for further activities that create partnerships between teacher education programs and neighboring public schools

Preservice Teachers’ Reflective Practices, Self- efficacy, and Professional Growth

This qualitative research study looks at how reflective practices support preservice teachers’ professional growth and development and its impacts on their self-efficacy. This study takes place in a regionally recognized south-western Hispanic Serving Institution that serves a high needs school district. Preservice teachers were asked to reflect on their field experiences to integrate theory and practice. The common themes that emerge contend that preservice teachers with a high sense of self efficacy maintain a better understand of classroom management with its connection to building relationships. Another significant finding indicates that preservice teacher’s reflective practices lead to self-efficacy and professional growth. These finding are significant to improving teacher preparation programs

Community Partnerships

An egalitarian model of university-school partnerships starts with a theoretical frame of equity and social justice. This qualitative research study sought to understand high school students’ perception of community service through an intergenerational university-high school-elementary school partnership. Data analysis consisted of detailed notes collected from university faculty who oversaw the focus group discussions and two graduate assistants who took observational notes.  These notes were analyzed and thematically organized.  The findings indicate that the students enjoyed the experience and were highly motivated to complete and read their community themed book for the younger children in their community.  This research contributes new knowledge to the field of community engagement and to the field of informal and formal education through its analysis of discussions on meaningful community service pertaining to university-school collaborative partnerships.

Occupational exposures to solar ultraviolet radiation of vineyard workers in Tuscany (Italy)

A study to quantify the UV exposure of vineyard workers was carried out using polysulphone dosimetry. The study took place in Tuscany (Italy) involving 32 vineyard workers, covering three different stages of the vine's growth. The level of personal exposure expressed as a function on the available ambient UV radiation was determined. We also assessed skin reflectance parameters, pre and post exposure. It was found that during spring backs received between 53% and 87% of ambient exposure and arms between 30% and 60%. During summer, the workers received on the back between 36% and 77% of ambient exposure and between 19% and 43% of ambient exposure on the arm. The comparison with the occupational UV exposure limit showed that all subjects received UV exposures in excess of the limit. The exposure of back of neck exceeded 10 SED (assumed as a threshold level of sun-adapted skin for Mediterranean subjects) in spring, which means that in the case of non sun-adapted skin and without sun protection, erythema can be induced in this targeted population. The cumulative exposure was also estimated under specific assumptions of UV exposure giving values in some cases higher than previous studies.

Personal UV exposure in high albedo alpine sites

Mountain sites experience enhanced UV radiation levels due to the concurrent effects of shorter radiation pathlength, low aerosol load and high reflectivity of the snow surfaces. This study was encouraged by the possibility to collect original data of personal dose on a specific anatomical site (erythemally effective UV dose on the forehead) of two groups of volunteers (ski instructors and skiers) in the mountainous areas of Italy (the Alpine site of La Thuile-Les Suches in Valle d’Aosta region). Personal doses were assessed using polysulphone dosimetry. Exposure Ratio (ER), defined as the ratio between the personal dose and the corresponding ambient dose (i.e. erythemally weighted dose received by a horizontal surface) during the same exposure period was taken into account. In addition measuring skin colours as biological markers of individual response to UV exposure, was also carried out on the forearm and cheek of each volunteer before and after exposure. The median ER, taking into account the whole sample, is 0.60 in winter, with a range of 0.29 to 1.46, and 1.02 in spring, ranging from 0.46 to 1.72. No differences in ERs were found between skiers and instructors in spring while in winter skiers experienced lower values. Regarding skin colorimetric parameters the main result was that both skiers and instructors had on average significantly lower values of luminance after exposure i.e. they became darker. It was found that the use of sunscreen and individual skin photo-type did not produce significant variations in ER across instructor/skier group by day and by seasons (p>0.05). It seems that sunscreen use only at the beginning of the exposure or in a few cases a couple of times during exposure (at difference with the specific instructions sheets), was not sufficient to change significantly skin colorimetric parameters across participants. In conclusion UV personal doses on the ski-fields are often significantly higher than those on horizontal surfaces and consistently more intense respect to personal doses received by sunbathers on the beach in central Italy (ER range: 0.09– 0.42). Given the high levels of exposure observed in the present study, specific public health warnings with regards to the efficacy of sun-protection behaviours (proper application and re-application of sunscreen and protective measures such as hats and sun glasses) should be adopted

Personal uv exposure on a ski-field at an alpine site

International audienceMountain sites experience enhanced ambient UV radiation levels due to the concurrent effects of shorter radiation path-length, low aerosol load and high reflectivity of the snow surfaces. <br><br> This study was encouraged by the possibility to collect data of personal UV exposure in the mountainous areas of Italy, for the first time. Personal UV exposure (expressed in terms of Exposure Ratio, ER) of two groups of volunteers (ski instructors and skiers) at the Alpine site of La Thuile (Valle d'Aosta region, Italy) was assessed using polysulphone dosimetry which was tested in a mountainous snow-covered environment. In addition measurements of biological markers of individual response to UV exposure such as skin colorimetric parameters were carried out. <br><br> It was found that snow and altitude of study site affect calibration curves of polysulphone dosimeters in comparison to a situation without snow. <br><br> The median ER, taking into account the whole sample, is 0.60 in winter, with a range of 0.29 to 1.46, and 1.02 in spring, ranging from 0.46 to 1.72. There are no differences in exposures across skiers and instructors in spring while in winter skiers experience lower values. UV exposures are not sensitive to the use of sunscreen across instructor/skier group by day or by seasons or by photo-type. With regard to colorimetric parameters, the main result was that both skiers and instructors had on average significantly lower values of L* and b* after exposure i.e. becoming darker but the inappropriate sunscreen use did not reveal any changes in skin colorimetric parameters except in one spring day. <br><br> In conclusions UV intensities on the ski-fields are often significantly higher than those on horizontal surfaces. Given the high levels of exposure observed in the present study, dedicated public heath messages on the correct sunscreen use should be adopted
