A method of comparing one-step M-estimates of location for heavy tailed distributions is proposed and investigated. Simulations indicate that the new procedure provides good control over Type I errors and has more power than do some other methods for dealing with heavy tailed distributions. (SLD)

In an effort to improve their achievement and confidence, girls at a London elementary school were segregated and taught subjects designed to counter traditional role limitations. Boys, meanwhile, felt their status was being undermined, and teachers were uncertain about the rightness of countering societal norms. (DM)

Explores issues in evaluating exemplary programs, including the measurement of the degree to which the program is exemplary or promising. Suggests that comparison (control) group analysis can mislead researchers about the effectiveness of a program and suggests the use of gain scores to identify exemplary programs. (SLD)

This study investigated which plants and animals Swiss children found most attractive and evaluated the effect of an educational programme on children's preferences for species. More than 4000 pupils (8-16 years old) from 248 classes participated in the study. Possible effects of the programme were studied with the help of questionnaires using a…

Previous research in alphabetic languages had shown that children learning to write are sensitive to morphological information, and that it serves as a resource that they draw upon as they acquire writing skills. In Chinese as well, sensitivity to morphological and orthographic information had been found to predict children's ability to read…

This research was designed to examine the effects of the use of individualized, learning-style based homework prescriptions on the achievement and attitudes of middle level students. Sixth-, seventh-, and eighth-grade students from an urban, parochial school in New York City were provided either learning-style-based homework prescriptions or…

In this article I discuss the factors that led me to implement study groups in the teaching of mathematics. An important influence in this decision began with an experimental study conducted with two College Algebra classes in which students were randomly assigned to treatment groups. While there was no statistical difference between the study…

Studies done in L1/L2 English settings have revealed the negative effects of writing anxiety on both learner motivation and academic achievement and teachers' attitudes towards writing and the practices they use in their own classes. The present study aims to find out the effects of peer feedback on the writing anxiety of Turkish prospective…

The main purpose of this study has been to compare the concept mapping with the traditional instruction method in consideration of student's achievements in English course. The students who took "English" class in 9th grade at Balakgazi High School in 2005-2006 attended this study. An experimental group and a control group consisting of 23 members…

In psychotherapy, effectiveness of an experimental treatment often is compared to care as usual. However, little if any attention has been paid to the heterogeneity of care as usual. The authors examined the effectiveness of manualized behavior therapy on school-aged disruptive behavior disordered (DBD) children in everyday clinical practice. A…

Ten-year-old students in an experimental group and a control group were tested for metacognitive abilities in reading comprehension before and after implementation of treatment in the experimental group. The teachers of the students in the experimental group were trained in metacognitive strategy instruction and in optimizing instruction time for…

This study investigated acquisition and transfer of the modeling ability of fifth graders in various domains. Teaching interventions concentrated on the topic of marine ecosystems either through a modeling-based approach or a worksheet-based approach. A quasi-experimental (pre-post comparison study) design was used. The control group (n = 17)…

The present study investigated the efficacy of using response cost paired with Differential Reinforcement of Incompatible Behavior (DRI) to manage the inattentive behavior of 30 students attending third and fourth grade in Jordan. A pretest-posttest control group design was employed to evaluate the efficacy of response cost and DRI. Results showed…

The purpose of this study was twofold: (a) to examine the effects of remedial reading instruction on the basic reading skills of elementary and middle school students with high-incidence disabilities (n = 45) and their comparison condition counterparts (n = 23); and (b) to examine the relative responsiveness of participating students with…

A new computerized environment introducing a variety of metacognitive support mechanisms (MSMs) in different phases of the problem-solving process was designed to influence students' transfer from solving structured problems (near transfer) to solving open-ended problems (far transfer). Two hundred and thirty one students (aged 13-14 years) were…
