Differences in Brain Activation Between Novices and Experts in Science During a Task Involving a Common Misconception in Electricity

Science education studies have revealed that students often have misconceptions about how nature works, but what happens to misconceptions after a conceptual change remains poorly understood. Are misconceptions rejected and replaced by scientific conceptions, or are they still present in students' minds, coexisting with newly acquired scientific conceptions? In this study, we use functional magnetic resonance imaging (fMRI) to compare brain activation between novices and experts in science when they evaluate the correctness of simple electric circuits. Results show that experts, more than novices, activate brain areas involved in inhibition when they evaluate electric circuits in which a bulb lights up, even though there is only one wire connecting it to the battery. These findings suggest that experts may still have a misconception encoded in the neural networks of their brains that must be inhibited in order to answer scientifically.     

Correlates of kindergarten adjustment: Temperament and communicative competence

The kindergarten adjustment of 217 Causasian children (mean AGE=70 months) was examined in relation to their temperament and communicative competence. Both communicative competence and various dimensions of temperament accounted for a significant proportion of the variance in kindergarten adjustment. Children who were evaluated as normal-to-advanced in their level of competence were found to be significantly more adjusted to kindergarten than were those assessed as delayed. Along with age and gender, the temperament dimensions of attention span-distractibility, rhythmicity, general activity level, and mood were significantly predictive of children's adjustment. An understanding of these factors can help parents and professionals promote a successful initial experience within the educational system.     

Notes from California: an anthropological approach to urban science education for language minority families

This article describes a unique and ongoing collaboration involving a team of bilingual/multicultural teacher‐educators, preservice teachers, teachers, students, and community members in an urban California elementary school. According to the model this team employed, children, teachers, and student teachers gather community “funds of knowledge” about the science to be studied in a classroom, then incorporate this knowledge by using parents as experts and by creating community books. In this model community‐generated materials parallel and complement standards‐based curricula, although science topics that have natural significance in particular communities are used as a starting point. Using critical ethnography as a framework, the article focuses on a particular experience—the building of a Mien–American garden house—to show how, by drawing on participants' funds of knowledge, a new kind of multiscience can emerge, one accessible to all collaborating members and responsive to school standards. © 2001 John Wiley & Sons, Inc.

International teachers negotiating 21st century science classrooms: a question of hybridized identities and pedagogical imaginaries

International high school science teachers are crossing international and cultural borders to teach, raising important issues in education. In this article, we describe the cross-cultural assessment challenges that four international science teachers encountered when they migrated to teach in the United States. These included differences in grade expectations for a given quality of work, the weight given to final examinations, the assessment process, and cutoff scores for letter grades. To become proficient in their new teaching contexts, the participating teachers had to modify (or hybridize) their assessment philosophies and practices in order to conform to the expectations of their new schools. This hybridization process ushered them into what is proposed as the Pedagogical imaginary; a transitional space between the ``purity' of their native educational conventions and that of their American schools. The implications of these findings are discussed in hopes of improving high school science teaching experiences for international science teachers. Deborah J. Tippins is a Professor in the Department of Mathematics and Science Education at the University of Georgia. She served as a Fulbright Scholar in the Philippines where she continues to explore notions of community-based science education. Her research interests include culturally relevant pedagogy, case-based science teaching and learning and post-structuralist feminist pedagogy and research. She is intensively involved in professional development of PreK-8 science teachers. In her spare time she likes to play tennis, travel and take her dog for long walks. Lorie Hammond is an Associate Professor in the Department of Teacher Education at California State University at Sacramento. Her work centers on community-based multicultural science education. For the past 10 years she has been leading action research projects centered in school-community gardens in diverse urban schools which serve as food security, oral history, science education, and service learning sites involving children, parents, teachers, and pre-service teachers. Lorie just co-edited a book, Innovations in educational ethnography: Theory, methods and results (2006), with George Spindler, and is finishing a book on how teachers can teach and learn with immigrant communities. She has recently been engaged in ethnographic and international research with immigrant women, developing relational and equalizing models of teaching and learning in immigrant communities.

He is the author of the book, Teaching in America: A cross-cultural guide for international teachers and their employers, and the upcoming book, Teaching diverse and urban learners: Research, best practices, and lesson planning. He is the recipient of Recognition and Key to the City of Boston, and has appeared on, or been featured by local and international news media. He was recently invited to participate in the Oxford Round Table at Oxford University, England. He teaches and provides professional development in science education, cross-cultural and urban education, and instructional strategies for diverse learners.     

Education makes a difference: Results of a survey of writing on the job

A survey of 182 employees participating in writing workshops reveals some differences in writing practices, based on the educational level of the employee, and suggests that employees with advanced degrees (e.g., master's or doctoral) vary most noticeably from the other groups. In particular, it seems that a large percentage of workers with graduate training write long reports, write to other experts in their field, and spend time revising. Additional research needs to be done on the impact of educational level on writing practices.     

Effects of locus of a brief stimulus in a second-order schedule with pigeons

On the completion by pigeons of four equal fixed intervals on one key, a light on a second key signaled that one peck on that key would be followed by food. In condition A, a brief stimulus of a further color was produced on the first key by the pecks that ended the first three (but not the fourth) fixed intervals. In condition B, no brief stimuli occurred at the end of the first three fixed intervals (tandem schedule). In condition C, the unpaired brief stimulus was presented on the second key after the pecks on the first key that ended the first three fixed intervals. An ABACA reversal design was used. Postreinforcement pauses were longer in condition B (tandem) than in condition A, an effect similar to that reported in similar conventional one-key second-order schedules. Postreinforcement pauses in condition C, with the brief stimulus on the second key, were also longer than in condition A, with the brief stimulus on the first key, although similar pauses were observed after the brief stimuli in both conditions. The locus of the brief stimulus appears to affect the control it exerts over behavior in a second-order schedule.
