The COVID-19 pandemic triggered the first global “Infodemic” in the era of social media. Understanding how governments deal with the negative impacts of the infodemic has become a priority. This paper uses the theoretical framework of the Elaboration Likelihood Model to explore mechanisms for alleviating panic associated with the infodemic. It considers, in particular, the quality of information circulated on Government Social Media as the central route and local government trust as the peripheral route. An empirical study was conducted using (...) data from a focus group interview and a questionnaire survey collected within the first three weeks following the citywide lockdown of Wuhan, China. The results show that as: Quality of GSM information does not significantly reduce public panic, but local government trust significantly increases people’s pandemic prevention knowledge; Pandemic prevention knowledge is a critical mediator between information quality of GSM and public panic, as well as local government trust and public panic; and Information quality of GSM significantly increases people’s trust in local governments. This paper contributes to the literature on infodemic and government social media and provides implications for practice. (shrink)

The representation of physics problems in relation to the organization of physics knowledge is investigated in experts and novices. Four experiments examine the existence of problem categories as a basis for representation; differences in the categories used by experts and novices; differences in the knowledge associated with the categories; and features in the problems that contribute to problem categorization and representation. Results from sorting tasks and protocols reveal that experts and novices begin their problem representations with specifiably different problem categories, (...) and completion of the representations depends on the knowledge associated with the categories. For, the experts initially abstract physics principles to approach and solve a problem representation, whereas novices base their representation and approaches on the problem's literal features.

The present paper analyzes the self‐generated explanations (from talk‐aloud protocols) that “Good” and “Poor” students produce while studying worked‐out examples of mechanics problems, and their subsequent reliance on examples during problem solving. We find that “Good” students learn with understanding: They generate many explanations which refine and expand the conditions for the action parts of the example solutions, and relate these actions to principles in the text. These self‐explanations are guided by accurate monitoring of their own understanding and misunderstanding. Such (...) learning results in example‐independent knowledge and in a better understanding of the principles presented in the text. “Poor” students do not generate sufficient self‐explanations, monitor their learning inaccurately, and subsequently rely heavily on examples. We then discuss the role of self‐explanations in facilitating problem solving, as well as the adequacy of current AI models of explanation‐based learning to account for these psychological findings.

In 2011 the Journal of Moral Education (JME) celebrated its 40th anniversary of publication. It seemed appropriate to examine and reflect on the JME?s achievements by reviewing its evolution and contribution to the emerging field of moral education and development. Moral education trends, as reflected in the 945 articles published in JME from 1971 to 2011, were investigated by content analysis. The research objectives were: to discover the trends in moral education as represented by published articles and special issues (by (...) analysis of disciplinary approaches, key topics, research methodologies and age-related educational levels) and to examine the international and gender-related development of the journal and the influence of its contributors (by analysis of first authors and editorial board members). The findings identify important concerns, key research topics and neglected areas in moral education and development. Analysis offers an insight into the contribution of JME as the main international interdisciplinary journal in this field, to the history of moral education, to theory and practice and in the changing socio-cultural contexts of the past 40 years. Discussion of the findings is offered, limitations are acknowledged and implications for future directions for the journal considered. (shrink)

Studies exploring how students learn and understand science processes such as diffusion and natural selection typically find that students provide misconceived explanations of how the patterns of such processes arise (such as why giraffes’ necks get longer over generations, or how ink dropped into water appears to “flow”). Instead of explaining the patterns of these processes as emerging from the collective interactions of all the agents (e.g., both the water and the ink molecules), students often explain the pattern as being (...) caused by controlling agents with intentional goals, as well as express a variety of many other misconceived notions. In this article, we provide a hypothesis for what constitutes a misconceived explanation; why misconceived explanations are so prevalent, robust, and resistant to instruction; and offer one approach of how they may be overcome. In particular, we hypothesize that students misunderstand many science processes because they rely on a generalized version of narrative schemas and scripts (referred to here as a Direct-causal Schema) to interpret them. For science processes that are sequential and stage-like, such as cycles of moon, circulation of blood, stages of mitosis, and photosynthesis, a Direct-causal Schema is adequate for correct understanding. However, for science processes that are non-sequential (or emergent), such as diffusion, natural selection, osmosis, and heat flow, using a Direct Schema to understand these processes will lead to robust misconceptions. Instead, a different type of general schema may be required to interpret non-sequential processes, which we refer to as an Emergent-causal Schema. We propose that students lack this Emergent Schema and teaching it to them may help them learn and understand emergent kinds of science processes such as diffusion. Our study found that directly teaching students this Emergent Schema led to increased learning of the process of diffusion. This article presents a fine-grained characterization of each type of Schema, our instructional intervention, the successes we have achieved, and the lessons we have learned. (shrink)

Active, constructive, and interactive are terms that are commonly used in the cognitive and learning sciences. They describe activities that can be undertaken by learners. However, the literature is actually not explicit about how these terms can be defined; whether they are distinct; and whether they refer to overt manifestations, learning processes, or learning outcomes. Thus, a framework is provided here that offers a way to differentiate active, constructive, and interactive in terms of observable overt activities and underlying learning processes. (...) The framework generates a testable hypothesis for learning: that interactive activities are most likely to be better than constructive activities, which in turn might be better than active activities, which are better than being passive. Studies from the literature are cited to provide evidence in support of this hypothesis. Moreover, postulating underlying learning processes allows us to interpret evidence in the literature more accurately. Specifying distinct overt activities for active, constructive, and interactive also offers suggestions for how learning activities can be coded and how each kind of activity might be elicited.

Human one‐to‐one tutoring has been shown to be a very effective form of instruction. Three contrasting hypotheses, a tutor‐centered one, a student‐centered one, and an interactive one could all potentially explain the effectiveness of tutoring. To test these hypotheses, analyses focused not only on the effectiveness of the tutors' moves, but also on the effectiveness of the students' construction on learning, as well as their interaction. The interaction hypothesis is further tested in the second study by manipulating the kind of (...) tutoring tactics tutors were permitted to use. In order to promote a more interactive style of dialogue, rather than a didactic style, tutors were suppressed from giving explanations and feedback. Instead, tutors were encouraged to prompt the students. Surprisingly, students learned just as effectively even when tutors were suppressed from giving explanations and feedback. Their learning in the interactive style of tutoring is attributed to construction from deeper and a greater amount of scaffolding episodes, as well as their greater effort to take control of their own learning by reading more. What they learned from reading was limited, however, by their reading abilities. (shrink)

This paper aims to bridge the relationship between metalinguistic if you like as a non-propositional discourse marker and its conditional counterparts. This paper claims that metalinguistic if you like is polysemous between a hedge that denotes the speaker’s reduced commitment to some aspect of the main clause, and an optional yet potential conditional reading that interlocutors can legitimately draw on in interaction which is brought about due to the ‘if p, q’ sentence form. That is, although the metalinguistic reading is (...) most likely obtained automatically by default, it also carries an available conditional reading that is akin to other metalinguistic conditional clauses such as if you see what I mean. Next, a semantic representation of metalinguistic if you like is developed that takes on board a characterization of conditionality that departs from lexico-grammatical conventions, such that conditionals of the form ‘if p, q’ no longer bear a one-to-one correspondence with “conditional” truth conditions. Employing a radical contextualist semantic framework in which the unit of truth-conditional analysis is not constrained to the sentence form, utterances employing metalinguistic if you like are given a semantic representation such that the if-clause does not contribute propositional content, yet they also maintain their status as conditionals as the sentence form gives rise to a potential conditional secondary meaning.

Based on a rather simple thesis that we can learn from our mistakes, Karl Popper developed a falsificationist epistemology in which knowledge grows through falsifying, or criticizing, our theories. According to him, knowledge, especially scientific knowledge, progresses through conjectures that are controlled by criticism, or attempted refutations . As he puts it, ‘Criticism of our conjectures is of decisive importance: by bringing out our mistakes it makes us understand the difficulties of the problem which we are trying to solve. This (...) is how we become better acquainted with our problem, and able to propose more mature solutions: the very refutation of a theory ... is always a step forward that takes us nearer to the truth. And this is how we can learn from our mistakes’ . Since criticism plays such a crucial role in Popper's falsificationist methodology, it seems natural to envisage his heuristic as a helpful resource for developing critical thinking. However, there is much controversy in the psychological literature over the feasibility and utility of his falsificationism as a heuristic. In this paper, I first consider Popper's falsificationism within the framework of his critical rationalism, elucidating three core and interrelated concepts, viz. fallibilism, criticism, and verisimilitude. Then I argue that the implementation of Popper's falsificationism means exposing to criticism various philosophical presuppositions that work against criticism, such as essentialism, instrumentalism, and conventionalism; it also means combating what seems a common tendency of humans to be biased towards confirmation. I examine the confirmation bias, to which Popper did not give much attention: its pervasiveness and various guises, some theoretical explanations for it, and the role of teachers in undermining its strength and spread. Finally, I consider the question whether students can and should be taught to use disconfirmatory strategies for solving problems. (shrink)

The goals of this study are to evaluate a relatively novel learning environment, as well as to seek greater understanding of why human tutoring is so effective. This alternative learning environment consists of pairs of students collaboratively observing a videotape of another student being tutored. Comparing this collaboratively observing environment to four other instructional methods—one‐on‐one human tutoring, observing tutoring individually, collaborating without observing, and studying alone—the results showed that students learned to solve physics problems just as effectively from observing tutoring (...) collaboratively as the tutees who were being tutored individually. We explain the effectiveness of this learning environment by postulating that such a situation encourages learners to become active and constructive observers through interactions with a peer. In essence, collaboratively observing combines the benefit of tutoring with the benefit of collaborating. The learning outcomes of the tutees and the collaborative observers, along with the tutoring dialogues, were used to further evaluate three hypotheses explaining why human tutoring is an effective learning method. Detailed analyses of the protocols at several grain sizes suggest that tutoring is effective when tutees are independently or jointly constructing knowledge: with the tutor, but not when the tutor independently conveys knowledge.

ICAP is a theory of active learning that differentiates students’ engagement based on their behaviors. ICAP postulates that Interactive engagement, demonstrated by co‐generative collaborative behaviors, is superior for learning to Constructive engagement, indicated by generative behaviors. Both kinds of engagement exceed the benefits of Active or Passive engagement, marked by manipulative and attentive behaviors, respectively. This paper discusses a 5‐year project that attempted to translate ICAP into a theory of instruction using five successive measures: (a) teachers’ understanding of ICAP after (...) completing an online module, (b) their success at designing lesson plans using different ICAP modes, (c) fidelity of teachers’ classroom implementation, (d) modes of students’ enacted behaviors, and (e) students’ learning outcomes. Although teachers had minimal success in designing Constructive and Interactive activities, students nevertheless learned significantly more in the context of Constructive than Active activities. We discuss reasons for teachers’ overall difficulty in designing and eliciting Interactive engagement. (shrink)

In this paper, we formulate and investigate a two-microorganism and single nutrient chemostat model with Monod-Haldane response function and random perturbation. First, for the corresponding deterministic system, we introduce the conditions of the stability of the equilibrium points. Then, using Lyapunov function and Itô’s formula, we investigate the existence and uniqueness of the global positive solution of the stochastic chemostat model. Furthermore, we explore and obtain the criterions of the extinction and the permanence for the stochastic model. Finally, numerical simulations (...) are carried out to illustrate our main results.

Sociologue et philosophe, Georg Simmel (1858-1918) fut sans aucun doute une des grandes figures de la transition socioculturelle de cette fin de siècle, face au désenchantement de cette époque où le développement technique a pris une telle ampleur que l'homme s'est senti écrasé par ses propres créations. Simmel s'est proclamé pour un renouveau dans la culture, "une spiritualité de la vie matérielle et une matérialisation de la vie spirituelle". Cette nouvelle orientation permet à l'homme de donner un sens et un (...) but à sa vie tout en gardant une unité entre l'objectivité et la subjectivité. L'objectif de cet ouvrage est de montrer l'actualité et la fécondité des analyses simmeliennes qui nous engagent à explorer la complexité des relations individu/société. Cette nouvelle thématique socio-philosophique concerne tous les domaines, aussi bien philosophiques, qu'artistiques et religieux. Simmel ne prétendait pas fonder une école, ni former des disciples, son but ultime fut d'élever la réalité sociale du présent vers un processus culturel allant du sujet vers l'objet et réciproquement. Dans son journal posthume, Simmel compare son oeuvre à de l'argent dont chacun peut s'approprier une partie qui lui servira pour ses propres recherches. La pensée simmelienne est une mine de richesse pour l'exploration de la société et de la culture et porte en elle les germes de la modernité. (shrink)

In this article, the researchers explore the following question. Can corporate social responsibility (CSR) and the corporate reputation of a firm lead to its brand equity in business-to-business (B2B) markets? This study discusses CSR from customers' viewpoints by taking the sample of industrial purchasers from Taiwan small-medium enterprises. The aims of this study are to investigate: first, the effects of CSR and corporate reputation on industrial brand equity; second, the effects of CSR, corporate reputation, and brand equity on brand performance; (...) and third, the mediating effects of corporate reputation and industrial brand equity on the relationship between CSR and brand performance. Empirical results support the study's hypotheses and indicate that CSR and corporate reputation have positive effects on industrial brand equity and brand performance. In addition, corporate reputation and industrial brand equity partially mediate the relationship between CSR and brand performance. (shrink)

In post-Gricean pragmatics, communication is said to be successful when a hearer recovers a speaker’s intended message. On this assumption, proposals for ‘what is said’ – the semantic, propositional meaning of a speaker’s utterance – are typically centred around the content the speaker aimed to communicate. However, these proposals tend not to account for the fact that speakers can be deliberately vague, leaving no clear proposition to be recovered, or that a speaker can accept a hearer’s misconstrual even though the (...) speaker didn’t intend it. In such cases, identifying ‘what is said’ is more contentious, even though communication is arguably no less successful. Building on recent interactionist approaches to meaning, this chapter offers a proposal for ‘what is said’ that can account for cases of ‘imperfect’ communication in which the recovery of a speaker’s intention goes awry. This involves taking ‘what is said’ as the co-constructed meaning that the speaker and hearer jointly agree on, giving ‘grounded meanings’ – those mutually and manifestly accepted into the discourse by speaker and hearer – higher precedence in a theory of communication than simply the speaker’s intended meaning. In such cases, rather than speaker and hearer converging at the level of explicit utterance content, communication is expected to be successful as long as the hearer recovers a proposition which is compatible with the speaker’s higher-order discursive goal. The hearer’s uptake is then allowed to override the content of the speaker’s intended meaning in the process of negotiating ‘what is said’. (shrink)
