全美教育协会教育专业伦理规范的制定及启示

我国历来有重视师德建设的传统,但通过制定规范推进师德建设的做法却一直效果不佳。全美教育协会教育专业伦理规范于1975年定稿以来,已沿用三十五年有余,并为许多国家、地区制定规范时所效仿。本文从制定主体、形成过程、执行制度及规范内容等方面,对比该规范与其他师德规范,展现其所体现出的教育专业自主、专业人员本位、专业自律、专业自由等特点,以期为我国师德规范建设提供一定参考。     

HSK口部动词研究及启示

口部动词是动词的特殊小类,也是对外汉语集合式词汇教学的一个重要集合。通过对《汉语水平考试词汇与汉字等级大纲》中口部动词的研究发现：口部动词可分为四类,且义项丰富,多义口部动词义项泛化的基本形式为：＂口部动作义→一般口部动作义→引申义或比喻义＂;口部动词的使用频度与大纲的设计基本一致。根据这一研究结果,对外汉语口部动词的教学可以遵循区分频度原则、分别释义原则和汉外对比原则以提高教学效果,并可以针对不同级别的学生确定不同的教学设计思路。

Characteristics of electricity consumption of different industry types considering atmospheric condition

Reducing greenhouse gases (RHG) is going on actively in the international movement. In the field of architecture, RHG is an inevitable work. To establish a plan for RHG, firstly we need to reduce energy consumption. Greenhouse gas generated by energy consumption is the main cause of global warming. For this we should know that how much electricity consumption we use. The research targets of this study are commercial buildings with various businesses. Their electricity consumption was analyzed by business units rather than buildings. Each business was divided into 13 sectors according to industrial classification and electricity consumption was analyzed for each industry. For commercial buildings, the electricity consumption is done by the private sector and construction management is an autonomy system in private instead of an integrated management system. In this study, we classified and analyzed the electricity consumption characteristics according to collected data, analyzed the relationship between the electricity consumption with atmospheric temperature through SPSS, and developed an electricity prediction model.

Learning Acetabular Fracture Classification using a Three-Dimensional Interactive Software: A Randomized Controlled Trial

Acetabular fractures are a real challenge for junior doctors as well as experienced orthopedic surgeons. Correct fracture classification is crucial for appreciating the fracture type, surgical planning, and predicting prognosis. Although three-dimensional (3D) tutorial is believed to improve the understanding of the complex anatomy structure, there have been few applications and randomized controlled trials to confirm it in orthopedics. This study aims to develop a 3D interactive software system for teaching acetabular fracture classification and evaluate its efficacy. Participants were randomly but evenly allocated into either the experimental group (who learned the acetabular fracture classification using a 3D software) or the control group (who used a traditional two-dimensional [2D] tutorial). Both groups were then tasked to classify 10 acetabular fractures and complete a five-point Likert scale on their satisfaction of each learning modality. To calculate significance (P < 0.05), independent t-test was used for normally distributed data whereas Mann-Whitney U test for non-normally distributed data. The experimental group significantly outperformed the control group (t (28) = 2.526, P = 0.017) with identifying correct acetabular fracture classification. Moreover, Likert scale score in the experimental group was also significantly higher than in the control group (Z = 2.477, P = 0.013). This 3D classification software has objectively and subjectively showed an advantage over the traditional 2D tutorial, resulting in an improved classification accuracy and higher Likert scale score. The 3D software has the potential to improve both clinical knowledge as well as identifying correct patient management in orthopedics.
