This paper argues that research into the pedagogical value and potential of new technologies is limited by the implicit philosophical perspectives on technology that such research adopts. These perspectives either imbue technologies with inalienable qualities (essentialism) or posit technology as a neutral means for realizing goals defined by…

People worldwide are faced with making decisions daily. While many decisions are quick (e.g., what clothes to wear), others, such as those about environmental issues (e.g., overfishing), require more thought and have less immediate outcomes. How one makes such decisions depends on how one interprets, evaluates, and uses evidence. The central…

One of my principal goals at the University of Minnesota is to transform the university's entry-level geoscience program into an effective ''concluding'' geoscience course that provides students with a clear understanding of the many interactions between Earth processes and human society. Although place-based learning appeared to be a promising…

This quasi-experimental study uses a pre-/post-intervention approach to investigate the quality of undergraduate students' arguments in the context of socioscientific issues (SSI) based on experiencing a semester of traditional "cookbook" instruction (N?=?79) or a semester of argument-based instruction (N?=?73) in the context of an…

The purpose of this investigation was to explore how aspects of identity, perceived levels of controversy, and the strength of a student's attachment to their controversial identity relate to conceptual understanding and knowledge acquisition during socioscientific issues (SSI) based instruction in a biology classroom. The knowledge gained from…

"Culture," a set of principles that trace and familiarize human beings within their existential realities, may provide an invisible lens through which reality could be discerned. Critically explored in this study is how culture- and language-sensitive curriculum materials in physics improve Pangasinan learners' attitude toward science.…

Electrochemical water oxidation is a major focus of solar energy conversion efforts. A new laboratory experiment has been developed that utilizes real-time, hands-on research to discover catalysts for solar energy conversion. The HARPOON, or Heterogeneous Anodes Rapidly Perused for Oxygen Overpotential Neutralization, experiment allows an array of…

Constructing and critiquing scientific arguments has become an increasingly important goal for science education. Yet, the differences in the ways students construct collaborative oral and individual written socioscientific arguments are not well established. Our research with one middle school class in an urban New England school district…

Forest ecosystems provide a suite of goods and services, including wood products as well as an array of ecosystem services and other non-timber goods and services. Despite an increasing emphasis on managing forests as holistic systems providing a portfolio of goods and services, silvicultural research has focused on maximizing production of…

Letting students deliberate on socio-scientific issues is a tricky affair. It is yet unclear how to assess whether, or even support that, students weave science facts into value-laden socio-scientific deliberations without committing the naturalistic fallacy of deducing "ought" from "is". As a preliminary step, this study…

Grand challenges stress the importance of multi-disciplinary research, a multi-actor approach in examining the current state of affairs and exploring possible solutions, multi-level governance and policy coordination across geographical boundaries and policy areas, and a policy environment for enabling change both in science and technology and in…

This study investigated the relationship between pre-service science teachers' written argumentation levels about socio-scientific issues and epistemic belief levels in an online discussion environment. A mixed-methods approach was used: 30 Turkish pre-service science teachers contributed with their written argumentations to four socio-scientific…

The reasoning belief of "argumentum ad nauseam" assumes that when someone repeats something often enough, he or she becomes more convincing. The present paper analyses the use of this strategy by seventh-grade students in an argumentation task. Sixty-five students (mean age: 12.2, SD?=?0.4) from a public school in a mid-sized urban…

The purpose of this study was to examine whether Socioscientific Issues (SSI) based learning environments affect university students' epistemological understanding of scientific inquiry differently from traditional science educational contexts. We identify and compare conceptions of scientific inquiry of students participating in an…

In this paper we analyze the influence of positivism in Argentina astronomical culture in the nineteenth century. We did the analysis from two dimensions, scientific knowledge development and science teaching. Because Argentina was a very young country at that time, it was of singular importance, not only the development of scientific knowledge…
