Korean 4‐ to 11‐year‐old student conceptions of heat and temperature

The aim of the present study is to shed light on the conceptions that young students have of heat and temperature, concepts that are both important in school science curricula and closely related to daily life. The subjects of the study were students from a rural district in South Korea and they ranged in age from 4 to 11 years. Interviews were conducted with each student on the basis of questions on temperature, thermal insulation, and heat equilibrium. After calculating the frequency and percentage of student responses and analyzing the rationale for their answers, it was found that younger students tended to view temperature as “size” or a “summation of numbers.” This tendency gradually diminished in older students. Most students had alternative conceptions of thermal insulation regardless of age; however, reasoning differed according to age. Younger students displayed a greater tendency to view insulation as a material property, whereas older students showed a greater tendency toward rational heat and temperature conceptions. Most students did not have clear concepts of heat equilibrium regardless of age, but possessed numerous alternative conceptions. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 44: 284–302, 2007     

Visual Short‐Term Memory for Complex Objects in 6‐ and 8‐Month‐Old Infants

Infants' visual short‐term memory (VSTM) for simple objects undergoes dramatic development: Six‐month‐old infants can store in VSTM information about only a simple object presented in isolation, whereas 8‐month‐old infants can store information about simple objects presented in multiple‐item arrays. This study extended this work to examine the development of infants' VSTM for complex objects during this same period (N = 105). Using the simultaneous streams change detection paradigm, Experiment 1 confirmed the previous developmental trajectory between 6 and 8 months. Experiment 2 showed that doubling the exposure time did not enhance 6‐month‐old infants' change detection, demonstrating that the developmental change is not due to encoding speed. Thus, VSTM for simple and complex objects appears to follow the same developmental trajectory.

This ten chapter volume intends to approach a number of current issues “from well‐established web‐based learning environments to mobile learning, through current web 2.0 applications such as blogs, which foster intercultural contexts and/or diverse means of computer‐mediated interaction”. In this sense, the valuable book aims to enable readers to gain a deep understanding of the field and to provide research procedures and processes to facilitate the learning of foreign languages through the use of information technology. If you expect the content of this book to be relevant to you, I recommend that you buy a copy for your own use. Jesús García Laborda
