Echoslamming: how incivility interacts with cyberbalkanization on the social media in Hong Kong

Cyberbalkanization has growingly become common on the Internet and can lead to public’s opinion polarization. This study investigates a specific process of cyberbalkanization through which incivility is circulated within online communities. From a dataset of Hong Kong-based Facebook Pages collected during a social movement, a set of politically-organized communities was identified and their connectivity generated a post-sharing network. A random sample of contents shared between and within these communities was then manually classified based on the level of incivility. The targets of offence through the use of uncivil language were also coded. Contents shared within ideologically compatible communities were found to be more likely to be uncivil. The association was significantly more positive in a populistic community, of which members had unique political nature and cultural norms. The targets were usually political opponents and incivility was adopted to petition detractors from within-community discussions. We therefore suggest ‘echoslamming’ is an online phenomenon through which uncivil contents catalyse anger toward political opponents among ideologically congruent information sources and consequently reinforce the audience’s predilection. Such a mechanism can be one underlying explanation for a vicious circle of cyberbalkanization-induced polarization on political opinions.     

A Call for Action (Research): Applying Science Education Research to Computer Science Instruction

In educational research, investigators in one field are often ignorant of similar research in other fields. Physics education in particular has undergone dramatic reforms in recent years, all based on insights gained from conducting educational research. Often, pedagogical methods resulting from research in one field can be revised and transferred to another. This paper demonstrates that many methods used in physics and other science programmes<fnr rid="b"> <fn id="b">Throughout this paper, programme will refer to the curricular concept and program will refer to computer programs.</fn> can be adapted to teaching computer science. The author has pursued action research in computer science and implemented ideas from science education, especially from physics education, in teaching computer science classes at a small religious secondary school in the southwestern United States. This paper presents ideas and teaching strategies with the hope of building bridges between computer science education research and other science education research.     

Not all preconceptions are misconceptions: finding ‘anchoring conceptions’ for grounding instruction on students’ intuitions

This study begins the task of mapping out the domain of valid, potentially helpful beliefs of students and raises the possibility of drawing on these intuitions in teaching conceptual material. Some issues are explored surrounding the identification of such intuitions, referred to as anchoring conceptions or anchors. We attempt to: (1) propose some organizing theoretical and observational definitions of the anchor construct; (2) present some initial findings from a diagnostic test designed to uncover anchors for physics instruction; and (3) provoke an initial discussion of the new methodological issues that arise in this domain.

The results of the diagnostic test indicate that a number of group anchors exist. In addition, some unexpected non‐anchors were identified. Furthermore, evidence was found indicating that some anchoring examples may be ‘brittle’, i.e., evidence that the anchor could not be extended analogically to help a student make sense of a target situation.

Finally, it is suggested that further research is needed to construct a theory of anchoring conceptions that would, for example, specify what characteristics would indicate that an anchoring conception can provide the basis for conceptual change via analogical extension.     

Values education as holistic development for all sectors: researching for effective pedagogy

The paper argues that values education has moved from being associated most heavily with the religious agenda of faith schools to being central to updated research insights into effective pedagogy. As such, it represents a vital approach to education in any school setting. The paper draws on an array of values education research and practice in making the case but centres especially on findings from a number of recent publicly funded projects in Australia with which the authors have been associated. Of special importance is evidence from the Values Education Good Practice Schools Project and the Project to Test and Measure the Impact of Values Education on Student Effects and School Ambience that provide both anecdotal and empirical evidence that high quality values education contributes to holistic educational development, including academic advancement, of students across all school sectors.     

Determinants of value transfer and contrast in simultaneous discriminations by pigeons

In a simultaneous discrimination involving a positive (S+) and a negative (S₋) stimulus, positive value appears to transfer from the S+ to the S₋. However, negative value does not appear to transfer from the S₋ to the S+. Instead, when sufficient experience with the contingencies associated with responding to the S₋ is provided, it appears that the presence of the S₋ enhances the value of the S+ (i.e., a contrast effect is found). The purpose of the present experiments was to further examine the influence of the S+ on the S₋ in a simultaneous discrimination (between subjects in Experiment 1 and within subjects in Experiment 2). In both experiments, we found that under typical training conditions, given little direct experience with the value of the S₋, value transfers from the S+ to the S₋. If sufficient experience with the value of the S₋ is provided, however, contrast between the S+ and the S₋ can be demonstrated. Thus, in a simultaneous discrimination, value transfer from the S+ to the S₋ depends on the animal’s having responded relatively little to the S₋.     

New Visuality in Art/Science: A Pedagogy of Connection for Cognitive Growth and Creativity

New visuality in art/science pedagogies challenges teachers to rethink their curriculum and the role of digital new media in facilitating conceptual thinking and the role of the creative representation of knowledge. Recent neuroscientific research on cognition, perception, memory, and emotion inform and provoke implications for 21st-century learning. Analysis of student artwork uncovers pedagogical challenges for teachers. Teachers use visual learning and its forms of higher process thinking to allow students to make cognitive connections with images, giving them the capacity to integrate concepts for the communication of art/science learning. Examples of student learning from years 3–5 and 15–17 illustrate these ideas.
