Scientific Inquiry in Educational Multi-user Virtual Environments

In this paper, we present a review of research into the problems of implementing authentic scientific inquiry curricula in schools and the emerging use of educational Multi-User Virtual Environments (MUVEs) to support interactive scientific inquiry practices. Our analysis of existing literature in this growing area of study reveals three recurrent themes: (1) with careful design and inclusion of virtual inquiry tools, MUVE-based curricula can successfully support real-world inquiry practices based on authentic interactivity with simulated worlds and tools, (2) Educational MUVEs can support inquiry that is equally compelling for girls and boys, and (3) research on student engagement in MUVE-based curricula is uneven. Based on these themes, we suggest that future large-scale research should investigate (1) the extent to which MUVE-based inquiry learning can be a viable substitute for the activities involved in real-world inquiry; (2) the impact of MUVEs on learning and engagement for currently underserved students, and (3) the impact on engagement and learning of individual aspects of MUVE environments, particularly virtual experimentation tools designed to scaffold student inquiry processes and maintain engagement. Additionally, we note that two identified issues with integrating scientific inquiry into the classroom are currently not addressed by MUVE research. We urge researchers to investigate whether (1) MUVE-based curriculum can help teachers meet state and national standards with inquiry curricula; and (2) scientific inquiry curricula embedded in MUVE environments can help teachers learn how to integrate interactive scientific inquiry into their classroom.

Operation ARA: A computerized learning game that teaches critical thinking and scientific reasoning

Operation ARA (Acquiring Research Acumen) is a computerized learning game that teaches critical thinking and scientific reasoning. It is a valuable learning tool that utilizes principles from the science of learning and serious computer games. Students learn the skills of scientific reasoning by engaging in interactive dialogs with avatars. They are tutored by avatars with tutoring sessions that vary depending on how well students have responded to questions about the material they are learning. Students also play a jeopardy-like game against a feisty avatar to identify flaws in research and then generate their own questions to determine the quality of different types of research. The research examples are taken from psychology, biology, and chemistry to help students transfer the thinking skills across domains of knowledge. Early results show encouraging learning gains.     

DEVELOPMENTALLY APPROPRIATE PRACTICES IN TEACHER EDUCATION: LESSONS FROM ONE SEMESTER

Abstract

A major challenge for teacher preparation programs and future teachers is learning to work skillfully with the diversity of children in American classrooms. This paper describes a tool developed to address this challenge: the Learning and Teaching Assessment System (LTAS). The LTAS is a performance‐based, curriculum‐embedded assessment tool designed to uncover young children's strengths in different curricular areas as well as their approaches to learning. Developed for use with children 3–8 years of age, the LTAS helps teachers understand what children know in relation to key concepts in the different disciplines as well as how they learn in order to further their learning in subsequent days and weeks of teaching. The development of the LTAS is based primarily on two theoretical frameworks: Leont'ev's activity theory and Gardner's theory of multiple intelligences. To examine the efficacy of the LTAS in its proposed objectives, a pilot study was conducted; results point to the potential of the LTAS for helping student teachers uncover new information about children to guide future instruction.     

Playful Postmodernism: Building with Diversity in the Postmodern Classroom

The authors surveyed program directors at all bachelor of social work and master of social work programs accredited by the Council on Social Work Education using an online tool that assessed whether and how their respective social work programs are covering content related to HIV/AIDS. Of the 650 program directors, 153 (24%) participated in the survey. Programs reported coverage of HIV/AIDS content in various foundation content areas, including human behavior in the social environment, populations at risk, and social work practice. The authors also surveyed use of various pedagogical methods, and respondents reported the most use of guest speakers, lectures, and readings in delivering HIV/AIDS content. More than 70% of bachelor and master of social work programs reported having at least 1 field placement specific to HIV/AIDS. In addition, the authors evaluated social work textbooks for specific content on social work with HIV/AIDS, and recommendations are made for inclusion of more HIV/AIDS specific content.     

Changing Roles and Professional Challenges for Human Performance Technology

From its roots in behavioral science and instructional systems design, the field of human performance technology has broadened significantly during the past three decades in terms of its interventions and the backgrounds and skills areas of its practitioners. This development brings with it many questions as to the field's definition, theoretical underpinnings, and future developments in research and practice. A brief review of the history of HPT, a survey of some of its leaders, and a model of the roots and branches of the field are presented.     

Key Strategies for Building Research Capacity of University Faculty Members

Universities are under pressure to increase external research funding, and some federal agencies offer programs to expand research capacity in certain kinds of institutions. However, conflicts within faculty roles and other aspects of university operations influence the effectiveness of particular strategies for increasing research activity. We review conventional approaches to increasing research, focusing on outcomes for individual faculty members and use one federally-funded effort to build cancer-related research capacity at a public university as an example to explore the impact of various strategies on research outcomes. We close with hypotheses that should be tested in future formal studies.     

Untangling the Threads: Networks,community and teacher learning in the National Writing Project

From 1998 to 2000, we studied two sites of the National Writing Project to find out whether network learning ever finds its way into teachers' classrooms. In the process of observing the 5-week invitational institute (purported to be the key to understanding the National Writing Project), we found that teacher learning and becoming engaged in a professional community revealed a set of social practices. These practices provide the core of this important professional development program-- a core that is recreated in sites all over the country, organized in a network-like organizational form. This complex, layered national network, at its best, provides a model for teacher development involving teachers in a professional community situated in teachers' practice.     

Phonological awareness: one key to the reading proficiency of deaf children

A case is made for the importance of children's development of phonological awareness--whether they are hearing or deaf--if they are to reach their potential as readers. Relevant terms are defined (i.e., phonological awareness, phonological processes, and phonics) to assist the reader with the research review, which covers (a) the typical stages in the acquisition of phonological awareness and (b) phonological awareness and deafness. Suggestions for phonological awareness assessment are offered, along with the recommendation that the use of recently developed formal and informal measures of phonological awareness might facilitate the setting of goals and objectives when deaf educators or speech-language pathologists are evaluating the skills of deaf students and planning instruction for these students. Such tools yield information about skills that have been shown to correlate with literacy attainment and that are not commonly addressed by deaf educators or speech-language pathologists serving deaf students. Finally, research concerning the facilitation of phonological awareness and its application is explained.     

Interactivity Between Protégés and Scientists in an Electronic Mentoring Program

Interactivity is defined by Henri (1992) as a three-step process involving communication of information, a response to this information, and a reply to that first response. It is a key dimension of computer-mediated communication, particularly in the one-on-one communication involved in an electronic mentoring program. This report analyzes the interactivity between pairs of corporate research scientists (mentors) and university biology students (protégés) during two consecutive implementations of an electronic mentoring program. The frequency and structure of the interactions within each pair were examined to provide context: 542 messages were posted among the 20 mentors and 20 protégés. These messages were formed into 5–10 threads per pair, with 3–4 messages per thread, indicating a high level of interactivity (there were more responses posted than independent messages). Mentor–protégé pairs rated as effective by both mentors and protégés posted more messages overall, had well-structured threads, had protégé and mentor postings that were similar in topic coverage and message length, and had little overt “management” behavior by mentors. However, there appears to be no clear recipe for successful interaction. Not only are there a variety of factors at play in developing an online relationship in this context, but mentor–protégé pairs can falter at various stages in the process and in various ways.
