EDINETE MARIA ROSA Federal University of Esp´ırito Santo, Brazil ∗ JONATHAN TUDGE University of North Carolina, Greensboro Urie Bronfenbrenner’s Theory of Human Development: Its Evolution From Ecology to Bioecology We describe the evolution, over three phases, of the time it was first proposed in the 1970s until Bronfenbrenner’s theory from an ecological to Bronfenbrenner’s death in 2005. It is therefore a bioecological theory.

Unfortunately, the individual (and those with whom he or she as Tudge et al. (2009) pointed out, this fact has typically interacts), both development over time been ignored by many scholars. Tudge et al. and the historical time in which these individuals analyzed 25 studies published between 2001 live, and the mechanisms that drive development and 2008 (i.e., well after the beginning of the (proximal processes). final stage in the theory’s development), whose From a methodological point of view, authors stated that their research was based on bioecological theory privileges the study of Bronfenbrenner’s theory. Of those, only four proximal processes that are likely to lead to were based on the most recent form of the healthy development, with the developing theory, and most described the theory simply individuals of interest being distinguished in as one of contextual influences on development, at least one relevant individual characteristic completely ignoring the centerpiece of the theory and studied in more than a single context in its final incarnation: proximal processes. As (almost always the typical settings in which Tudge et al. argued, there is nothing wrong with the individuals are to be found). The theory deliberately basing one’s research on an earlier was formulated, as Bronfenbrenner expressed version of the theory or even on a subset of its it, to examine not ‘‘the forces that have shaped key concepts; however, for theoretical confusion human development in the past, but . those to be avoided, one should be explicit about the that may already be operating today to influence specific theoretical basis for the study.

Bronfenbrenner and Evans (2000) noted them, or expanding on them. But this can occur that the first theory-related publications were only if scholars base their work on an accurate published from 1970 to 1979, marking the first reading of the theory as it currently exists or if phase in the theory’s evolution.

Supporting or attacking a reduced, theory concentrated primarily on a description old, or simply incorrect version of the theory The Evolution of Urie Bronfenbrenner’s Theory 245 is neither helpful nor appropriate. Therefore, (e.g., home, school, neighborhood) and with our goal here is to describe the three phases people with whom those children either live or in the development of Bronfenbrenner’s theory are familiar (1973, 1977c, 1979b). Lab-based as it matured into its final form, analyzing the research, by contrast, is typically conducted in principle characteristics and reformulations of an unfamiliar setting by a researcher unknown each phase. To attain this goal, we first identified to the child (1973, 1977a), something that all the published papers by Bronfenbrenner or Bronfenbrenner argued calls into question the with Bronfenbrenner as a first author that were validity of the results (1973, 1979b). Even related to the construction of his theory of human when research was conducted in the settings development. We were considerably aided in in which children are situated, Bronfenbrenner this task by the bibliographic chapter published noted that the researchers’ focus was far more by Luscher¨ and Jones (1995), which provides on the organism (the person) than on the setting a fairly complete and accurate listing of all (1975, 1977a, 1979b), the latter being described his scholarly work published until 1994.
