Science and technology are connected to each other and are mutually inspiring. The science-technology curriculum for junior-high school in Israel suggests that teachers integrate these subjects. In addition, this curriculum calls for infusing thinking competencies into the learning subjects and for implementing alternatives in assessment methods in the classes. The current research included three stages: field research, pilot research and expanded research. In the field research, an intervention program was planned and implemented. The intervention program included a three-year inservice training workshop consisting of 224 hours each year. Quantitative and qualitative tools were used to assess teachers implementation of the intervention program. The findings revealed the characteristics of the science-technology learning environment and various learning outcomes. The pilot research enabled the development and validation of a questionnaire called the Science-Technology Learning Environment Questionnaire (STLEQ). The STLEQ was aimed at assessing teachers and pupils perceptions of learning environment. The conclusions from the pilot research showed differences between teachers and pupils perceptions towards the impact of learning environment characteristics on learning outcomes.In the expanded research, two cohorts of pupils participated, namely, the 2002 cohort (N = 207) and the 2003 cohort (N = 159). These cohorts had studied science-technology in junior-high school. The findings of the expanded research partly match the findings from the pilot research, leading to insight into the pupils perspective of the science-technology learning environment. No gender differences were found in pupils scoring of learning outcomes. On the other hand, boys scored higher than girls on Computer Usage. This research enables researchers and teachers to use the questionnaire in order to investigate pupils perceptions of their learning environment. 相似文献

ABSTRACTChanges in information communication technology across the Asian region have altered our field substantively and methodologically. The rapid growth of digitized communications allows us to find new purchase in examining questions fundamental to our understanding of communication theories, norms, and practices across Asia. While methods such as text mining and user analytics are increasingly popular among computational scholars, here, we focus on online field experiments, an approach to studying communication that has the potential to overcome many existing obstacles to social scientific inquiry but one that has been used relatively rarely in Asia. In this paper, we discuss what online field experiments are and how they differ from traditional experiments as well as online lab and survey experiments. We show how researchers can go about designing and implementing online field experiments, focusing on issues where online field experiments differ from their traditional counterparts – legal and ethical considerations, construct validity, randomization and spillover, and statistical analyses. Finally we discuss how online field experiments can advance our understanding of communication in Asia by helping researchers to gain insight and make causal inferences on attitudes, behaviors, and interactions that were previously unobservable ?. 相似文献

只有将多元化教学模式应用到动物生理学实验教学中,才能更好地发挥出实验教学的作用,才能让学生积极主动地参与到学习活动中,这对于提高学生对实验教学的兴趣,培养学生创新意识,增强学生自主学习意识,提升教师教学能力也有非常深远的意义。为充分发挥多元化教学模式对动物生理学实验教学的价值作用,从而促进动物生理学实验教学质量的提升。作者以《动物生理学实验教学中多元化教学模式探索》为课题,从在动物生理学实验教学中采用多元化教学模式的必要性入手,对其进行了全面而深入的分析,并在此基础上探析了实验教学方式的多元化,同时也探究了考核形式的多元化。 相似文献

The aim of this explorative study was to develop and test a pedagogy aimed at promoting students’ ability to perform historical contextualization. Teaching historical contextualization was conceptualized in terms of four pedagogical design principles: (1) making students aware of the consequences of a present-oriented perspective when examining the past, (2) enhancing the reconstruction of a historical context, (3) enhancing the use of the historical context to explain historical phenomena and (4) enhancing historical empathy. The effectiveness of these principles was explored in a lesson unit focusing on the seventeenth and eighteenth centuries. In a quasi-experimental pre-test–post-test design with experimental and control conditions, the effects of the pedagogy on 15- and 16-year-old students’ ability to perform historical contextualization were examined (n = 131). The results indicated that students in the experimental condition significantly improved their ability to perform historical contextualization compared to students in the control condition. These findings could be used to help teachers and other educational professionals design and implement historical contextualization tasks and instructions. 相似文献

通过对《壮语通用词与方言代表点词汇对照汇编》一书中139个动物名词音义关系的考察表明:壮语通用词汇中的动物名词有相当一部分是有音义联系的,除了有一部分是摹仿动物之声而形成的词外,还有从外形(包括体型和动态)特征、内在性质等命名的,同样具有联想比附的思维模式。尤其在对汉语早期词汇的借用和改造(转换)过程中表现出壮民族面对强势语言从容应对的机敏。 相似文献
