Conversation as a key to the understanding of human nature∗

Using the transactionist perspective in our communication with others involves constructing those others with whom we communicate. An exercise called “Reflections” focuses on the inferences, assumptions, and guesses we make as we select from the cues others give off — cues necessary for the process of determining our definition of them. Useful in secondary, community college and college classrooms, “Reflections” can serve as a valuable, interesting, and unique classroom experience. This essay discusses the implementation and the outcome of the exercise as well as some of the reactions students have to it.     

Report on the CSEET '99 Workshop: “Establishing a Distance Education Program”

The objectives of the workshop were to examine five particular aspects relevant to software engineering distance education: how to turn existing courses into distance mode, the implications of cultural issues in establishing the program and in the delivery of material, how to ensure the quality of courses, how to ensure comparability of experience for students, and the range of delivery mechanisms which have been tried and assessed. The two-staged operation and results of the workshop are reported. Initial position statements are detailed and the analysis from five separate subgroups that addressed a case study as stage one of the process is presented. The second stage, of different subgroups addressing the four operational scenarios, is described and the feedback obtained from these groups is then presented. Finally a summary of the major work-shop findings is given, along with some overall conclusions.     

Bridging the Gap? A Comparative,Retrospective Analysis of Science Literacy and Interest in Science for Indigenous and Non‐Indigenous Australian Students

Previous research has shown that indigenous students in Australia do not enjoy equal educational outcomes with other Australians. This secondary analysis of PISA 2006 confirmed that this continues to be the case in science literacy for secondary students. However, the analysis also revealed that indigenous Australian students held interest in science equal to that of their non‐indigenous peers, and that observed variations in science literacy performance were most strongly explained by variations in reading literacy. These findings hold important implications for teachers, teacher educators, policy‐makers, and researchers. Firstly, acknowledging and publicly valuing indigenous Australian science knowledge through rethinking school science curriculum seems an important approach to engaging indigenous students and improving their literacy in science. Secondly, appropriate professional learning for practising teachers and the incorporation of indigenous knowing in science methods training in teacher preparation seems warranted. Additionally, we offer a number of questions for further reflection and research that would benefit our understanding of ways forward in closing the science literacy gap for indigenous students. Whilst this research remains firmly situated within the Australian educational context, we at the same time believe that the findings and implications offered here hold value for science education practitioners and researchers in other countries with similar populations striving to achieve science literacy for all.     

Developing a Managed Learning Environment Using 'Roundtables': An Activity Theoretic Perspective

To support and continue the motivation of participants in virtual learning environments it is important to achieve a successful learning atmosphere. Therefore, it is necessary to reach the participants on a personal level and to perceive their personal needs and emotions when conversing with them. These factors of learning motivation depend on the individual perception of virtual, text-based communication. The coding and encoding of purely, text-based language requires an enormous amount of compensation with regard to the absence of all verbal means of communication. For this reason it is important to determine the existence of any gender differences in the compensation for non-verbal communication or in the perception of text-based communication. In this study the gender gap in the perception of text-based communication was evaluated. The individual production and perception of text-based communication could be one reason for the decrease in the number of female participants in the majority of virtual learning environments. The objective of this survey was to define the characteristics of text-based communication, which then gives an indication of the condition of male and female participants of virtual learning environments. The results of this study provide information in relation to individual gender interpretation and production of written messages, as well as the implementation of measures which support the motivation to learn.     

Enhancing the Student Experiment Experience: Visible Scientific Inquiry Through a Virtual Chemistry Laboratory

Practical work is often noted as a core reason many students take on science in secondary schools (high schools). However, there are inherent difficulties associated with classroom practical work that militate against scientific inquiry, an approach espoused by many science educators. The use of interactive simulations to facilitate student inquiry has emerged as a complement to practical work. This study presents case studies of four science teachers using a virtual chemistry laboratory (VCL) with their students in an explicitly guided inquiry manner. Research tools included the use of the Inquiry Science Implementation Scale in a ‘talk-aloud’ manner, Reformed Teaching Observation Protocol for video observations, and teacher interviews. The findings suggest key aspects of practical work that hinder teachers in adequately supporting inquiry and highlight where a VCL can overcome many of these difficulties. The findings also indicate considerations in using the VCL in its own right.     

未来气候变化对鄱阳湖区土地利用变化的影响评估

为了评估未来气候变化可能对鄱阳湖区土地利用变化产生的影响,本文根据IPCC的建议,利用新近建立的基于主体的土地利用变化模拟模型,详细分析了4种气候变化情景下鄱阳湖区1985-2035年的土地利用变化过程。这4种气候变化情景分别为A1B(经济高速增长模式)、A2(区域经济多样化增长模式)、B1(引进更多清洁能源的经济增长模式)和情景4(无气候变化模式)。在这些气候变化情景中,由于耕地的农业生产潜力差异显著,农户主体的收入和他们对土地利用方式的决策也发生了相应的改变。通过对这一过程的模拟和结果分析,发现气候变化可能有利于鄱阳湖区土地利用变化向着环境友好的方向自我调整。与A1B和A2两种气候变化情景相比,B1情景对土地利用变化的影响更具环境友好性。     

Value of Family and Group Counseling Models Where Grandparents Function as Parents to their Grandchildren

Those involved in circumstances in which children are raised by their grandparents often encounter serious problems that require assistance from counselors. Research suggests that grandparents and parents in these families typically experience heightened stress and psychosocial distress. Additionally, the children often encounter behavioral, emotional, and academic difficulties. These difficulties usually occur partly as a result of the factors that lead to grandparents having to assume responsibility for the children. This paper provides a report of the phenomenon, particularly as it relates to the various members’ psychosocial well-being. In addition, family and group counseling are advanced as valuable relational psychotherapeutic models to enhance the well-being of the children, grandparents and parents involved.     

The female fish is more responsive: gender moderates the BFLPE in the domain of science

Academic self-concept is positively related to individual achievement but negatively related to class- or school-average achievement: the big-fish–little-pond effect (BFLPE). This contrast effect results from social comparison processes. The BFLPE is known to be long-lasting, universal and robust. However, there is little evidence regarding its generalisability across genders. Females, as opposed to males, feel more attached to their peers and compare themselves more often. Thus, it was hypothesised that the BFLPE is larger for females. This was investigated with a focus on science self-concept in a German sample from an extension of the Programme for International Student Assessment 2006 study (N?=?35,015) using recent advances in multilevel modelling. Replicating previous findings, females reported lower self-concepts while controlling for achievement. Additionally, the BFLPE was replicated. However, its effect size was substantially larger for females (?.41) compared to males (?.30). The implications of the results are discussed in light of women’s persisting underrepresentation in science, technology, engineering and mathematics fields.     

How do teachers perceive cheating students? Beliefs about cues to deception and detection accuracy in the educational field

The present study explores how well teacher trainees can detect liars. Moreover, a new method was applied to investigate beliefs that teacher trainees hold about liars. The results indicate that, overall, teacher trainees were not better than chance in detecting true and invented stories. Generally, participants reported to have used only a few cues for their credibility judgment, where most of these self-reported cues are stereotypical and invalid deception cues (e.g., gaze aversion). Further analyses with a Brunswikian lens model showed that the self-reported cues were good predictors of their credibility judgment but only poorly predictive for the objective truth/lie status of the statement. Practical implications of the results are discussed.
