Differences in electronic exchanges in synchronous and asynchronous computer-mediated communication: the effect of culture as a mediating variable

Two hundred and eighty undergraduates from universities in two countries were asked to read didactic material, and then think and write about potential solutions to an ill-defined problem. The writing was conducted within a synchronous or asynchronous computer-mediated communication (CMC) environment. Asynchronous CMC took the form of email exchanges between American learners only, Southern European learners only, and American and Southern European learners together. Synchronous CMC was restricted to dyads consisting of American–American, Southern European–Southern European, and American–Southern European students dialoguing. Additionally, a number of Americans and Southern Europeans were each paired with a content-“mirroring” computer-generated partner to account of the effect of thinking with an unresponsive partner in synchronous CMC. Results revealed that dyadic learners in asynchronous CMC used significantly more reasoning skills to think about solutions to the problem, while dyadic learners in synchronous CMC exchanged significantly more personal knowledge and features of emotion. However, the tendency among dyadic learners to include emotional features in their dialogues was mediated by their cultural background.     

Polemics and synthesis: Ernst Mayr and evolutionary biology

Mayr has justifiably earned for himself the title “Darwin of the 20th century”. He declared himself Darwin's champion, and was particularly wont to point out that a most important consequence of the Darwinian revolution was the destruction of typological thinking. Mayr also repeatedly stressed that there were important differences between Darwinism and contemporary theories of evolution. Evolution as conceived by Darwin was not goal-directed, while contemporary theories were orthogenetic or aristogenetic in the sense that they believed in a predetermined progression of lower to higher forms. Furthermore, by focusing on individuals, Darwin destroyed the tyranny of typological thinking, which was a left over from the essentialism of Plato, who believed that groups of organisms were constructed according to certain homogeneities. By attacking the concept of essentialism, Darwin provided a mechanism by which individuals became both a focus and an essential ingredient in the evolutionary process. This was a paradigm shift and according to Mayr, a conceptual leap that constituted a true scientific revolution. Mayr's zeal in defending Darwin and in protecting organismal biology and evolution from the “non-believers” has formed the subject of this entire article, but it can also be seen in the titles of some of his recent books, e.g.One Long Argument. Charles Darwin and the Genesis of Modern Evolutionary Thought (1991),This is Biology—the Science of the Living World (1997), andWhat Evolution Is (2002).     

Understanding Children's Comprehension of Visual Displays of Complex Information

Developing students' ability to interpret the vast amount of quantitative data they encounter on a daily basis has become a major task for today's educators. However, very little attention has been given to students' strategies of analyzing multivariate data. This study investigated how students interpret and analyze multivariate data organized in tables and the nature of external visual displays that they tend to create and use for this purpose. Ten middle school students were asked to think aloud while solving five problems demanding an analysis of data organized in tables. The students were then interviewed. Results indicated that (1) students based their conclusions on only part of the data; (2) students did not use either efficient or sufficient visual representations; (3) students did not apply mathematical operations efficiently; and (4) students referred to or built a context to the problem. The results of the current research may assist educators to design efficient curricula while being aware of and taking into account (1) students' difficulties in employing previously learned mathematical devices to analyze data, (2) students' skills in choosing appropriate and efficient visual representations to present and interpret the data, and (3) strategies employed by students in analyzing multivariate data.     

Integrating pharmacology topics in high school biology and chemistry classes improves performance

Although numerous programs have been developed for Grade Kindergarten through 12 science education, evaluation has been difficult owing to the inherent problems conducting controlled experiments in the typical classroom. Using a rigorous experimental design, we developed and tested a novel program containing a series of pharmacology modules (e.g., drug abuse) to help high school students learn basic principles in biology and chemistry. High school biology and chemistry teachers were recruited for the study and they attended a 1‐week workshop to learn how to integrate pharmacology into their teaching. Working with university pharmacology faculty, they also developed classroom activities. The following year, teachers field‐tested the pharmacology modules in their classrooms. Students in classrooms using the pharmacology topics scored significantly higher on a multiple choice test of basic biology and chemistry concepts compared with controls. Very large effect sizes (up to 1.27 standard deviations) were obtained when teachers used as many as four modules. In addition, biology students increased performance on chemistry questions and chemistry students increased performance on biology questions. Substantial gains in achievement may be made when high school students are taught science using topics that are interesting and relevant to their own lives. © 2003 Wiley Periodicals, Inc.

Perspectives on the transition from preschool to kindergarten for children with disabilities and their families.

This article addresses the transition of young children from preschool programs that provide special education services to kindergarten or alternative elementary school placements. The roles of the child, family, and service providers in transition preparation, planning, implementation, and evaluation are described. Successful transitions include assessments of children's skills in meeting the demands of kindergarten programs, teaching these skills to children, and actively encouraging parent participation in plans and programs. Barriers to successful transitions include lack of time and funding to coordinate both parent activities and between-school arrangements. A critical area for future research is the long-term evaluation of the procedures described as "best practice," as well as the definition of what constitutes a successful transition.     

A preliminary investigation of the concurrent validity of reading comprehension rate: A direct,dynamic measure of reading comprehension

Reading comprehension rate (RCR) is a direct measure of reading skills that may be useful in formatively evaluating students reading beyond the fourth‐grade level. To investigate the concurrent validity of RCR, we correlated RCR, reading comprehension level (RCL), and words correct per minute (WC/M) with the Broad Reading Cluster Scores of the Woodcock‐Johnson III Tests of Achievement (WJ‐III ACH) across 88 students in 4th, 5th, and 10th grades. Results showed that aloud‐RCR was significantly correlated with the WJ‐III ACH scores for 4th‐grade (r = .90; n = 22), 5th‐grade (r = .87; n = 29), and 10th‐grade (r = .65; n = 37) students. Regression analysis specified a one‐predictor model for 4th‐grade students (aloud‐RCR), a two‐predictor model for 5th‐grade students (WC/M and aloud‐RCR), and a one‐predictor model for 10th‐grade students (WC/M). Discussion focuses on directions for future research and applied issues related to RCR probe passage development. © 2007 Wiley Periodicals, Inc. Psychol Schs 44: 373–388, 2007.     

Examining Educational Climate Change Technology: How Group Inquiry Work with Realistic Scientific Technology Alters Classroom Learning

This study with 79 students in Montreal, Quebec, compared the educational use of a National Aeronautics and Space Administration (NASA) global climate model (GCM) to climate education technologies developed for classroom use that included simpler interfaces and processes. The goal was to show how differing climate education technologies succeed and fail at getting students to evolve in their understanding of anthropogenic global climate change (AGCC). Many available climate education technologies aim to convey key AGCC concepts or Earth systems processes; the educational GCM used here aims to teach students the methods and processes of global climate modeling. We hypothesized that challenges to learning about AGCC make authentic technology-enabled inquiry important in developing accurate understandings of not just the issue but how scientists research it. The goal was to determine if student learning trajectories differed between the comparison and treatment groups based on whether each climate education technology allowed authentic scientific research. We trace learning trajectories using pre/post exams, practice quizzes, and written student reflections. To examine the reasons for differing learning trajectories, we discuss student pre/post questionnaires, student exit interviews, and 535 min of recorded classroom video. Students who worked with a GCM demonstrated learning trajectories with larger gains, higher levels of engagement, and a better idea of how climate scientists conduct research. Students who worked with simpler climate education technologies scored lower in the course because of lower levels of engagement with inquiry processes that were perceived to not actually resemble the work of climate scientists.     

The Influence of Afrocentric Spirituality on Counselling Stigma and Help-Seeking Perceptions among Nigerian Americans

This empirical study examined the relations between Afrocentric spirituality and psychological help-seeking attitudes, intentions, and stigma among Nigerian adults living in the United States of America (N = 122). Participants completed a demographic questionnaire, the Spirituality Scale (Jagers and Smith in Journal of Black Psychology, 22, 429–442, 1996), the Perception of Stigmatization by Others for Seeking Psychological Help Scale (Vogel et al. in Journal of Counseling Psychiatry, 56, 301–308, 2009), the Self-Stigma of Seeking Help Scale (Vogel et al. in Journal of Counseling Psychology, 53, 325–337, 2006), the Intention to Seek Counselling Inventory (Cash et al. in Journal of Counseling Psychology, 6, 111–112, 1975), and the Attitudes Toward Seeking Professional Psychological Help Scale-Short Form (Fischer and Turner in Journal of Consulting and Clinical Psychology, 1, 79–90, 1970). Results from multiple regression analyses indicated that there was no relation between Afrocentric spirituality and help-seeking attitudes or self-stigma about seeking counselling. However, there was a positive correlation between Afrocentric spirituality and other-perceived stigma, demonstrating that increased Afrocentric spirituality predicted increased perceived stigma from others about seeking counselling services. Contrary to expectations, there was a positive correlation between Afrocentric spirituality and intentions to seek counselling. Implications for counselling practice and theory are presented.
