“More meaningful to do it than just reading it:” rehearsing praxis among Mexican-American/Latinx pre-service teachers

ABSTRACT

This paper explores the potential use of drama-based pedagogical tools to prepare future bilingual teachers to respond to the need for advocacy inside and outside the classroom. Using their lived experiences and class material, 20 Mexican-American/Latinx bilingual pre-service teachers performed real-life narratives of conflict experienced by local seasoned bilingual teachers during a foundational class in a preparation program in the Southwest. Using Boal’s Forum Theater, these reenactments provided bilingual pre-service teachers with a context to develop assertiveness and positionality as a means to co-construct emergent bilingual advocate-teacher identities. This paper uses critical ethnography and critical discourse analysis of video-recorded reenactments of bilingual pre-service teachers, as well as interviews and reflections.     

Enhancement of Quality in Chemical Inquiry by Pre-University Students

Our pre-university chemistry students face problems achieving sufficient quality in chemical inquiry. To try to enhance the quality of student performance in chemical inquiry, Dutch pre-university chemistry students (age 17) carried out an authentic research project on Diffusion of ions in distilled water. The learning materials for this student inquiry project, the teaching scenario and the website were designed in cooperation with five chemistry teachers. Three teachers from this network and two other teachers also implemented the project with 80 students to find out whether the emphasis on relevant concepts of evidence (CoE) improves the quality of student inquiry outcomes. This part – with its emphasis on the CoE – in the student inquiry task is based on four key features: the students feel motivated to explore, focus their attention on, give meaning to and reflect upon CoE. In teams students conducted a guide experiment, analysed a scientific article, did an inquiry and wrote a report, discussed CoE with peers on the Internet and rewrote their reports. All lessons were observed, field notes were made and analysed on whether the intended student activities had been realised. The Internet discussion was recorded in a database and analysed. The first and final reports of all teams were coded and analysed. Also the students appreciation of the activities was assessed. The teaching and learning activities were realized to a very large extent as planned in the design. The emphasis on CoE resulted in 65% of the students achieving a sufficient level of quality in their final reports.     

雷氏大疣蛛毒素-V的分离纯化与初步活性鉴定

雷氏大疣蛛(Macrothele raveni)是最近发现的异仿蛛科大疣蛛属的蜘蛛新种.雷氏大疣蛛毒素-V就是以该蜘蛛粗毒为原料,利用阴、阳离子交换层析和反相高效液相色谱分离纯化得到并命名的一种新型蜘蛛毒素.利用基质辅助激光解析电离飞行时间质谱仪分析得知它的相对分子质量为3133.48;通过初步活性研究证明雷氏大疣蛛毒素-V是一种昆虫专一性神经毒素.     

The Q theory of investment, the capital asset pricing model,and asset valuation:a synthesis

The paper combines Tobin's Q theory of real investment with the capital asset pricing model to produce a new and relatively simple procedure for the valuation of real assets using the income approach. Applications of the new method are provided.     

高校学生党建工作绩效评价体系的构建

将学生评价的理念方法引入高校党建评价中并衍生出新型绩效评价体系,其从学生党建工作质量评价和高校基层党建负责人绩效评价两个方面出发并结合受访者人口学特征,构建了13项二级指标和39项三级指标。通过建立二元Logistic回归模型进行指标贡献度评估,于实证中阐明该体系的运用机制并客观评价具体研究案例,经验分析证实了该体系于实践层面中的可推广性与可检验性,希望对科学评价与完善高校学生党建工作有一定的借鉴价值。
