The aim of this paper is to question the way one conceives the use of a specific theoretical approach (i.e., theories associated with the concept of complexity) in order to promote changes in educational practices and theories. The position I am adopting translates the conviction that any reform of thought has to be conceived in conjunction with a reflection about the idea of reform itself (Morin, 1999). It is therefore assumed that the use of the notion of complexity, to be critical and to bring significant changes, supposes not only to use a specific theoretical vocabulary, but also and above all to change the way scientific activity itself is conceived in order to bring about such a transformation. Following Edgar Morin’s constructivist and non-dualistic contribution, this paper discusses concepts such as program, strategy, prescription, interpretation, monoreferentiality and multireferentiality, in order to discuss researchers’ implication and the way they manage the relationships between the conditions of production of scientific discourses and the ″realities″ to which they are referring.

This chapter situates the conception of language (and communication) in enaction in the context of the research program of the cognitive sciences. It focuses on the formulation of the synthesis of hermeneutics and speech acts and the vision of language according to the metaphor of structural coupling. The exclusion of expressive speech acts in this design is problematized. An examination is offered of the critical steps to the theory of language as a reflection and the linguistic correspondence of cognitivism. We examine the foundations of the proposal in the line of language and social enaction as emergent phenomena which are not reducible to autopoiesis but which constitute a new neurophenomenological position in the pragmatic language dimension. A proposal is made for the integration of hermeneutic phenomenology with genetic and generative phenomenology in social semiotics. The inclusion of expressive speech acts based on the functions of language in the Habermas–Bühler line is also addressed. An opening is proposed of enaction to the expressive dimension of language and meaning holism with the referential use of language.

Key words: enaction, neurophenomenology, performative speech acts, expressive speech acts, background, meaning holism.

Upshot: For communicating second-order science, von Foerster’s ethical imperative provides a viable starting point. Proceeding from this, we plead in favour of emphasising the common grounds of diverging scientific opinions and of various approaches in second-order science instead of focussing on the differences. This will provide a basis for communication and stimulate scientific self-reflection.

The course on nature coincides with the re-working of Merleau-Ponty’s breakthrough towards an ontology and therefore plays a primordial role. The appearance of an interrogation of nature is inscribed in the movement of thought that comes after the Phenomenology of Perception. What is at issue is to show that the ontological mode of the perceived object – not the unity of a positive sense but the unity of a style that shows through in filigree in the sensible aspects has a universal meaning, that the description of the perceived world can give way to a philosophy of perception and therefore to a theory of truth. The analysis of linguistic expression to which the philosophy of perception leads opens out onto a definition of meaning as institution, understood as what inaugurates an open series of expressive appropriations. It is this theory of institution that turns the analysis of the perceived in the direction of a reflection on nature: the perceived is no longer the originary in its difference from the derived but the natural in its difference from the instituted. Nature is the “non-constructed, non-instituted,” and thereby, the source of expression: “nature is what has a sense without this sense having been posited by thought.”\\The first part of the course, which consists in a historical overview, must not be considered as a mere introduction. In fact, the problem of nature is brought out into the open by means of the history of Western metaphysics, in which Descartes is the emblematic figure. The problem consists in the duality at once unsatisfactory and unsurpassable – between two approaches to nature: the one which accentuates its determinability and therefore its transparency to the understanding; the other which emphasizes the irreducible facticity of nature and tends therefore to valorize the viewpoint of the senses. To conceive nature is to constitute a concept of it that allows us to “take possession” of this duality, that is, to found the duality. The second part of the course attempts to develop this concept of nature by drawing upon the results of contemporary science. Thus a philosophy of nature is sketched that can be summarized in four propositions: 1) the totality is no less real than the parts; 2) there is a reality of the negative and therefore no alternative between being and nothingmess; 3) a natural event is not assigned to a unique spatio-temporal localization; and 4) there is generality only as generativity.

This special issue invites a reflection on and reformulation of options for social construction as a theoretical and practical approach to studying communication as continuously emergent in relationships, constitutive of social reality, consequential to communicators, experienced through the bodily senses, and afforded by their material circumstances. Authors are encouraged to take stock of our predicted and actual accomplishments, consider the tensions between the promised and actualized changes brought about by social construction work in communication, and project the impact of social construction on the discipline in the next five to ten years. The focus is not only critical, but reflexive: How do we wish to reconstruct social construction? Relevance: The articles in the journal critically address social construction, taking on issues of its possibilities, shortcomings, and practical applications in psychotherapy, communication, and medicine.

Excerpt: The main thesis of this chapter is that the culture of teacher education must share the core characteristics of the desired mathematics classroom culture. In particular, this relationship must hold if teacher education is to exercise a reforming influence on in-service teachers and create a break in the circle of reproduction by which the weaknesses of the existing school system are perpetuated. It follows that more attention should be devoted to the relation between alternative classroom experiences and theoretical instruction, to the fundamental role of everyday language for the understanding of mathematics, the balance of self-directed work and the negotiation of meanings in seminars and tutorials, and to the development of reflection and self-monitoring.

Constructivism is an important theory of learning that is used to guide the development of new teaching methods, particularly in science education. However, because it is a theory of learning and not of teaching, constructivism is often either misused or misunderstood. Here we describe the four essential features of constructivism: eliciting prior knowledge, creating cognitive dissonance, application of new knowledge with feedback, and reflection on learning. We then use the criteria we developed to evaluate five representative published articles that claim to describe and test constructivist teaching methods. Of these five articles, we demonstrate that three do not adhere to the constructivist criteria, whereas two provide strong examples of how constructivism can be employed as a teaching method. We suggest that application of the four essential criteria will be a useful tool for all professional educators who plan to implement or evaluate constructivist teaching methods.

We characterize Rolando García’s view on science, as outlined on his writings on science and university policy, and then we trace this view on his constructivist epistemology. Through this lens, we analyze his review and reformulation of Jean Piaget’s constructivist theory, his subsequent reflection on interdisciplinary research of complex systems. Based on this analysis, we outline the current challenges for a constructivist epistemology.

After its infant stage, a new science usually starts reflexing on its identity and theoretical roots. Sustainability science is not an exception, and the needs of self-reflection are even more pressing because of its inter- and trans-disciplinary characters, which involve a plenty of different approaches, theories and practices. In fact, such a variety does not provide a consistent ground for its future development. Without a solid grounding on a reliable base, the plethora of different theories that currently crowds its arena could in the near future produce a rejection from disciplinary specialized researchers, thus confining sustainability science to a scientific fad. Convincing theoretical roots can be found in systems science and cybernetics, and in particular second-order cybernetics, once amended from autopoiesis theory and radical constructivism, which raise serious doubts of validity and applicability. If sustainability science acknowledged its systemic and cybernetic nature and adopted second-order cybernetics in its amended version, it would gain a powerful reference paradigm and a theoretical common denominator and language to support its researchers and facilitate their knowledge exchange. From their part, systems science and cybernetics would be better understood and embraced as powerful sources of knowledge for understanding modern challenging problems, and second-order cybernetics, after decades of scarce relevance for other scientific disciplines, would be revitalized and would finally evolve adequately in a promising science and social practice.

Key words: complexity, cybernetics, first-person account, recursivity, second-order, self-organization, sustainability, systems science.
