Learning oceanography from a computer simulation compared with direct experience at sea

Considerable research has compared how students learn science from computer simulations with how they learn from “traditional” classes. Little research has compared how students learn science from computer simulations with how they learn from direct experience in the real environment on which the simulations are based. This study compared two college classes studying introductory oceanography. One class learned using an interactive computer simulation based on a dynamic, three‐dimensional model of physical oceanography. The other class learned by spending a day on a research ship using scientific tools and instruments to measure physical properties of the ocean directly. In classes preceding and following the simulation or field experience, students performed the same exercises regarding currents and salinity, had the same instructor presentations, and did the same homework. The study found that the field experience helped contextualize learning for students with little prior experience of the ocean while the simulation made it easier for students to connect what they learned from it to other content they learned in class. These and other findings shed light on what computer simulations can and cannot help students learn, and what concepts are best learned in the real environment. © 2005 Wiley Periodicals, Inc.

Co-teaching in the college classroom

This paper serves as a phenomenological reflection about the meaning of a co-teaching experience at the college level for two graduate teaching assistants. When two teachers combine planning and teaching efforts it is called co-teaching. As a pedagogical method for both instructors and students, co-teaching was beneficial because it modeled a collaborative teaching style required of the students in their curricular work. Utilizing the interpretivist discourse of phenomenology, the authors dialog about the meaning each makes of the coursework, the pedagogy, the students, and the teacher effectiveness through a co-teaching model. The dialog and reflection on the phenomenon of co-teaching contributes to more productive co-teaching instruction for pre-service teacher instructors.     

Preservice preparation of teachers of the deaf in the twenty-first century: a case study of Griffith University, Australia

The provision of educational services to students who are deaf or hard of hearing in the compulsory school years in Australia has seen a shift from exclusive, isolated settings in the 1970s to an inclusive approach personalized to cater to the diversity of those students requiring educational support. Universities that undertake specific programs to train teachers of the deaf need to respond proactively to ensure that graduates are able to provide services in all types of school environments. The present study concerns the evaluation of preservice teachers of the deaf by their university, by their teacher mentors, and through their own assessment of the skills required to be a teacher of the deaf. The study's overall conclusion is that programs for preservice teachers of the deaf can produce high-quality graduates and that graduates undertake postgraduate study after some years of teaching.     

Employment outcomes for people in Australia who are congenitally deaf: has anything changed?

The employment of deaf school leavers is considered by means of data from a recent study conducted in South Australia (Winn, 2005). Its findings are compared with those of three other Australian studies conducted over the past several decades (Australian Federation of Adult Deaf Societies, 1973; Deaf Society of New South Wales, 1998; Hyde, 1988). Compared to the rest of the community, deaf adults have had and continue to have higher unemployment rates, are underemployed in terms of the range of occupations, and typically earn less than the general population in similar occupations. The most recent study (Winn, 2005) provides evidence that Australian deaf adults have poor employment outcomes despite access to higher education and legislation prohibiting discrimination. That employment outcomes have not altered dramatically since earlier studies suggests that positive programs are required to address the general community's attitude about deafness as a disability.     

How do pre-kindergarteners spend their time? Gender,ethnicity, and income as predictors of experiences in pre-kindergarten classrooms

The current paper considers how children spend their time in state-funded pre-kindergarten programs and how time use relates to ethnicity, gender, and family income, based on the assumption that how time is spent in pre-kindergarten is relevant for the programs’ success in narrowing achievement gaps. Classroom observations of 2061 children in 652 pre-k programs in 11 states were analyzed. Findings indicated that the pre-kindergarten day was roughly equally divided among free choice, teacher-assigned activities, and meals/routines. Children spent much of their time in language/literacy, social studies, and art, and less time in math and gross motor activities. Much of the pre-k day was spent in ‘no coded learning activity.’ Children in classes with lower proportions of Latino and African American children and higher average income-to-need ratios were generally engaged in richer and more stimulating experiences. The child-level variables of ethnicity and income were generally unrelated to how children spent their time, above and beyond the effects of classroom-level ethnicity and income. There were generally small, but significant gender differences – always in the gender-stereotyped direction – in how time was spent, especially during free choice time.     

Research Methods and Types of Evidence for Research in Educational Technology

Recent concern about lack of scientific rigor in educational research has led to a reexamination of educational research methods. Methodology requires particular attention when researchers study learning in complex learning environments such as classrooms or computer-driven environments that simulate complex processes. This article reaffirms the importance of experimental research for answering some research questions. It argues that nonexperimental methods, such as design experiments and methods applied to the study of large-scale educational programs, such as randomized field trials, are useful for answering other kinds of research questions about learning in complex settings. This article discusses the validity of evidence gathered using these nonexperimental methods. Finally, it suggests that the study of the dynamics of learning can help integrate data from experiments that reveal details about learning and data from nonexperimental research that reveal how learning occurs in complex settings.     

Preschool to kindergarten transition patterns for African American boys

This study focused on the transition patterns of African American boys from preschool to kindergarten using the Early Childhood Longitudinal Study – Birth Cohort (ECLS-B) dataset. Analyses were conducted to examine whether socioeconomic status, parenting (i.e., emotional support, intrusiveness), and attendance in a center-based program predicted likelihood of being in a particular transition pattern. Four patterns emerged from the data: (1) Increasing Academically, (2) Early Achiever: Declining Academically & Socially, (3) Low Achiever: Declining Academically, and (4) Consistent Early Achiever. There was heterogeneity in the school transition patterns of African American boys, with many showing stability from preschool to kindergarten. Family income and parenting practices and interactions were associated with an increased probability of being in the group that showed a significant increase in academics, suggesting the importance of parents’ provision of enriching opportunities and experiences for African American boys as they transition from preschool to kindergarten.
