单摆测重力加速度的比较研究

用单摆测重力加速是中学物理较重要的实验,本文应用传统方法、计时器、传感器三种测量方式对重力加速度进行测量。三种测量方法均在误差范围内,结果发现利用传感器测量结果误差最小。     

武术套路是技击的艺术化

探讨套路与技击的关系及套路的艺术特征，主要结论：套路与技击是同属于武术范畴，具有交叉关系的两个概念，攻防含义是它们的共同内容，但这两之间有着根本区别，技击以克敌制胜为主要目的，而套路以表现美为其最高追求，套路在素材的选择，动作创编，动作表现等方面都力求高度的艺术性，同时，套路动作也反映出其创编对攻防的感悟，不同时代，不同地区的武术套路有不同的风格。     

Assessment by project work in snow engineering

Assessment in the form of a large project and field- and laboratory work was shown to be successful when applied to a course in snow engineering for university students with various backgrounds. The course was interdisciplinary, with teachers representing three different engineering disciplines. The project work was assessed by a report, a short oral presentation and an optional presentation such as a home page, a poster or a physical model. The students experienced that they had learned more with this assessment strategy than from courses with a final written exam. Peer evaluation of the relative contributions to the project work was applied and was appreciated by the students. The experiences of practical engineering tasks during the project work were also appreciated.

Ground level ozone exposure and distribution over the historical Peninsula of Istanbul

In this study, passive samplers were used to measure ozone exposure distribution maps over the historical peninsula of Istanbul, Turkey. The study area is partially important due to the presence of cultural and historical buildings and structures distributed all over the peninsula. Unesco's World Heritage list covers four zones located in this historical peninsula in Istanbul. It is necessary to evaluate the pollution distribution in high resolution to construct effective risk management strategies. For this purpose, 50 sampling stations were installed within the study area. Three sampling campaigns within different seasons (summer, winter and fall) showing different ozone distribution characteristics were carried out. Seasonal measurements of ozone exposure values were used to obtain a yearly exposure level, which is an important part of risk characterization. Seasonal ozone exposure maps over the historical peninsula were obtained using Geographical Information Systems (GIS) based interpolation models with high resolution. Risk maps including five regions, based on ozone exposure levels were created. Structures and historical regions located within these risk zones were identified. Based on the defined exposure regions, we found that the Archaeological Park, one of the items on UNESCO's list, is located within the most risky region.     

Schooling sexualities and gendered bodies. Experiences of LGBT students in Icelandic upper secondary schools

In this paper, we study how Lesbian, Gay, Bisexual and Transgender people (LGBT) students in Icelandic upper secondary schools interpret their experience of heteronormative environment and how they respond to it. The aim is to explore how sexualities and gendered bodies are constructed through ‘schooling’. The article draws on interview data with seven LGBT students who attended five different upper secondary schools. We also use visual data collected during fieldwork at one upper secondary school and exemplify the results with a poster and a digitalised short-film, produced by the students, to substantiate what participants told us in the interviews. All of the students experienced heteronormative discourse and lack of respect and indicated that they did not feel fully accepted in school. Upon entering the classroom, the visibility of LGBTs and discussion about different performances of gender and sexuality seem to disappear, whether in terms of textbooks, course content, teaching practices and school environment. Furthermore, LGBTs and those who do not conform to the hegemonic performances of gender are often constructed as deviations from the norm, strange, and even depicted as the abjected other. This applies in particular to the informal school, which embraces the traditions, culture and social interactions among students and teachers. This othering occurs, despite relatively positive attitudes towards LGBT people in Icelandic society in general. The results signify a gap between policy and practice as regards the positioning of LBGT students, which affects their schooling and well-being.     

The Effect of Computer-Assisted Learning Integrated with Metacognitive Prompts on Students’ Affective Skills

The purpose of this study is to investigate the effect of computer-assisted learning integrated with metacognitive prompts on elementary students’ affective skills on the subject of electricity. The researchers developed educational software to enable students to easily and comprehensively learn the concepts in the subject of electricity. A case study method was used. Eighteen students from the seventh grade (12–13 years) participated in the study. Students’ views on their performances while using educational software and the impact of the software on their affective skills towards the subject of electricity were examined. Data were collected by open-ended questions in the educational software. According to the research results, there were students who had negative attitudes and perceptions before starting to learn about the subject of electricity. Interactive activities, animations, and visual experiments in the educational software were effective in overcoming the students’ negative attitudes and perceptions about the subject. Besides, students who assessed their own performances during the learning process believed themselves to be more successful over time. In the light of the research results, some suggestions are made for future studies.     

The Effects of the Preschool Inclusion Program on Teacher Outcomes in Turkey

The aim of this study was to evaluate the effects of a teacher training program on teacher outcomes. The teachers’ knowledge and attitudes regarding inclusion, classroom management strategies, and their relationships with children both with and without disabilities were evaluated using self-report instruments. In addition, their classroom behaviors were evaluated by independent observers. The teacher education program included a variety of topics related to inclusion and effective strategies for inclusive classrooms. The data were collected prior to the education, after the completion of the program, and 6 months afterwards. The results indicated that the teacher program seemed to have moderate-to-large effects on all teacher outcomes, but the changes in their classroom behaviors were minimal.     

Visual autocorrelation of prices

Paintings are in essence about visual features of varying significance from which differences in their market prices originate. Studies normally investigate derivative sources of painting price determinants, which is reasonably understandable because the appreciation of an image is quite subjective. This paper provides an operational solution to the quantification of paintings based on a new concept termed as “visual autocorrelation” of prices (VAP). Considering the current empirical framework of spatial and temporal autocorrelation of prices, and using data on the paintings of two abstract expressionist artists, empirical results support the coherence of the VAP concept.
