Use of Computers as a Tool in Fine Art

A treatment group of three sections of a college art design class was given instruction that included the use of computers to complete design projects. The art design course covers the basic concepts of design and two-dimensional materials and the use of line, colour, illusion of space or mass, texture, value, shape, and size in composition. A control group of three sections completed the same assignments as the treatment group without computers. Both groups of students were then surveyed about their attitudes toward using computers in the course. Both the treatment group and the control group perceived the use of computers in a basic art design class as worthwhile. Both groups perceived the use of computers in a basic art design class as enhancing instruction. The treatment group had a more positive response to the computer as a design tool than did the control group. Survey responses by the treatment group documented that design projects used in the study needed improvement. Further studies should focus on best practices in the use of computers in art education.     

Anorexia athletica in pre-professional ballet dancers

Competitive sport has been under increasing discussion as a possible favourable factor in the development of eating disorders among children and adolescents. The aim of this study was to determine the frequency of sport-specific eating disorders, in line with the concept of anorexia athletica. This prospective field study included one experimental group and two control groups (disease and healthy). Fifty-two pre-professional ballet dancers aged 13-20 years were tested for clinical eating disorders, anorexia athletica criteria, eating disorder related psychopathology and self-concept, and were compared with 52 patients with anorexia nervosa and 44 non-athletic controls of the same age. The study was conducted using semi-structured interviews as well as self-report questionnaires. A clinical eating disorder diagnosis was made in 1.9% of the ballet dancers versus 0% of the high school students; anorexia athletica was diagnosed in 5.8% of the dancers versus 2.3% of the students. Ballet dancers scored lower than patients with anorexia nervosa with regard to eating disorder related psychopathology and higher than the patients with regard to self-concept. We conclude that more sensitive tools to differentiate between sport-specific (eating) patterns, anorexia athletica and clinically relevant eating disorders are needed, especially for aesthetic sports such as ballet. It remains an important goal to identify athletes with symptoms of anorexia athletica irrespective of their physique and/or sport.     

Infantile Amnesia: Through a Glass Darkly

Memory for former preschool classmates was examined in 9-and 10-year-old children using measures of both explicit and implicit memory. Yes-no recognition of faces was at low levels but was significantly above chance. Skin conductance data showed similarly low but above-chance differentiation between classmates and controls. A median split of children based on their recognition memory scores showed that children with little evidence of explicit memory for classmates were as likely to show differential skin conductance responding to faces of former classmates as were children with higher recognition scores. Infantile amnesia, like the clinical syndrome for which it is named, may not always involve complete loss of encoded information.     

What Satisfies Students? Mining Student-Opinion Data with Regression and Decision Tree Analysis

To investigate how students' characteristics and experiences affect satisfaction, this study uses regression and decision tree analysis with the CHAID algorithm to analyze student-opinion data. A data mining approach identifies the specific aspects of students' university experience that most influence three measures of general satisfaction. The three measures have different predictors and cannot be used interchangeably. Academic experiences are influential. In particular, faculty preparedness, which has a well-known relationship to student achievement, emerges as a principal determinant of satisfaction. Social integration and pre-enrollment opinions are also important. Campus services and facilities have limited effects, and students' demographic characteristics are not significant predictors. Decision tree analysis reveals that social integration has more effect on the satisfaction of students who are less academically engaged.     

The Development of Hierarchical Representation of Two-Dimensional Space

Adults represent the location of a point in a 2-dimensional space using 2 independent dimensions. They encode location along these dimensions both at a fine-grained level and categorically. In reporting location, they combine and weight the fine-grained and categorical information. In Experiment 1, we found that children as young as 5 years use the same 2 independent dimensions in fine-grained spatial coding of location in a circle as are used by adults—radius and angle. However, categorical coding and hierarchical combination are seen only for radius, at both 5 and 7 years. The adult pattern, where angle as well as radius is coded hierarchically, emerges by 9 years. Experiment 2 shows that there is nothing intrinsically difficult about the categorical coding of angular information; when angle is the only dimension to be encoded, younger children use hierarchical coding. Changes in 2-dimensional hierarchical coding may be due to cognitive load factors and to changes in ability to assign frames of reference.     

Differential impacts of academic and social experiences on college-related behavioral outcomes across different ethnic and gender groups at four-year institutions

The results of the study indicated that institutional experiences, academic achievement, and environmental pull factors contributed the most to persistence decisions. Furthermore, analyses revealed that differences in the effects of these factors for different ethnic and gender groups were important in explaining persistence decisions. No precollege factors (educational aspirations, prior academic achievement, attitudes toward learning, and support and encouragement to attend college) were found to improve the overall fit of the models for any of the groups in the study. For minorities, the biggest detrimental effects on dropout behavior were derived from pull factors in the form of family responsibilities and working off-campus. No significant positive effects from informal and formal interactions with faculty, close personal relationships with peers, and academic experiences during their first year in college were found to negate the large negative influences from the pull factors. For females, the most significant positive effect on college persistence came from mentoring experiences in the form of nonclassroom interactions with faculty.     

Investigating cognitive change as a dynamic process / Investigar el cambio cognitivo como proceso dinámico

Abstract

In this introduction to the special issue ‘Dynamic aspects of cognitive development and learning’ we emphasize the current need for studies that address, in depth, the dynamic aspects of cognitive development and learning. We integrate cognitive development and learning into the concept of cognitive change. We then reflect on the scope and limitations of certain procedures that are implemented to turn these processes of cognitive change into limited objects of empirical research. This reflection will allow us to ask ourselves about the potential and validity of studies resulting from these procedures to inform educational and health-related practices. After presenting some methodological alternatives to explain cognitive change in a more productive way, we present the six studies that make up this special issue. The selection seeks to offer a rich repertoire of ideas; data collection, analysis and visualization methods; and evidence and explanations of situated processes of change in an evolutionary-educational arc extending from the first months of life in the context of familiar interactions, to adult learning.     

觅情

Amber swam with the rushing evening tide, coasting on the high-rising waves that continued to clap onto the California beach late into the evening. She had to hurry; tonight was the last night and she needed to make good use of her time. She could feel her hunger and need growing stronger with each passing moment,     

Is differential exposure to college linked to the development of critical thinking?

This study investigated the influence on critical thinking of differential exposure to postsecondary education. The sample was 2,076 first-year students attending 13 four-year and 4 two-year institutions from around the country. First-year students attending college full-time developed a higher level of critical thinking skills than those attending part-time. In the presence of controls for precollege critical thinking and academic motivation, the average critical thinking of first-year students at the institution attended, gender, race, age, and kinds of courses taken, the number of semester hours for which the student was enrolled had modest but significant positive effects on end-of-first-year critical thinking for both the two- and four-year college samples. In the two-year, but not the four-year, sample the relationship between semester hours and critical thinking deviated significantly from linearity. Students attending a two-year college full-time still derived the largest critical thinking benefits. However, the lowest levels of critical thinking accrued to those enrolled between 7 and 20 semester hours. Students enrolled for 6 or less hours actually had somewhat higher end-of-first-year critical thinking.
