Cognitive process development as measured by an adapted version of Wechsler's Similarities test

This paper studies the development of taxonomic processing as measured by an adapted version of the Wechsler Similarities subtest, which distinguishes between categorization of concrete and abstract words. Two factors — age and concreteness — are also tested by a recall task. The results show an age-related increase in taxonomic categorization, especially for abstract words; this change is more pronounced for the categorization task than for the recall task. The concreteness effect is also shown to be greater for categorization. A weak correlation between the recall of concrete and abstract words suggests that different processes are linked to dual coding of concrete words. However, the strong correlation between the categorization of concrete and abstract words testifies to a general factor in this task. Finally, age- and concreteness-related effects increase as the task gains in complexity. In conclusion, we discuss the role of immediate memory in cognitive functioning.     

The role of social support in well-being and coping with self-reported stressful events in adolescents

OBJECTIVE: This study investigated the role that social support plays in well-being and in coping after a stressful event in a group of non-clinical adolescents. Furthermore, this study aimed at replicating the finding that adolescents who reported sexual abuse reported more symptoms and less adequate coping strategies than adolescents who reported another type of stressful event or no stressful episode. METHOD: Eight hundred and twenty adolescents between 12 and 18 years of age filled out questionnaires assessing social support (Social Support Questionnaire, Sarason, Shearin, Pierce, & Sarason, 1987), trauma-related symptoms (Trauma Symptom Checklist for Children, Briere, 1996), behavior problems (Youth Self-Report, Achenbach, 1991), and coping (How I Cope Under Pressure Scale, Ayers, Sandler, West, & Roosa, 1996). RESULTS: 42% of the adolescents reported a stressful experience, and 4.4% reported sexual abuse. Sexually abused adolescents reported more stress-related symptoms and used more avoidance and fewer support-seeking coping strategies than the other adolescents. The main-effect hypothesis of social support was sustained, but social support did not moderate the relation between a stressful event and coping. Yet, a trend was found suggesting that high support from the family was associated with less avoidance coping and more support-seeking in adolescents who reported a non-sexually abusive, stressful event. CONCLUSIONS: Our findings show that a highly perceived availability of social support is directly associated with fewer trauma-related symptoms, especially in adolescents who are non-sexually abused. For adolescents who reported a sexual or another type of stressful event, social support did not play a different role in coping.     

Metacognitive factors in scientific problem-solving strategies

The aim of this study on 42 seventh graders (ages 12–13) was to determine whether and to what extent students’ metacognitive level is linked to their conceptualization and performance in problem solving at school, especially science problems. This hypothesis is supported by a number of studies showing that metacognition is a factor in learning. Two indexes were devised for the study: an index of metaknowledge about classroom learning, and an index of metacognitive monitoring in relation to task difficulty on a non-academic problem. These two indexes were related to the students’ intelligence test scores and solving strategies on electricity problems. The results showed that (1) the metaknowledge level was more closely tied to crystallized intelligence (Gc), and (2) metacognitive monitoring was more closely associated with fluid intelligence (Gf). Moreover, both metacognitive indexes were strongly linked to scientific problem-solving strategies (correlations around .50).     

Prevention of fatherhood disorders — Accompanying early father-child interaction in day-care centers

Over the last fifteen years, increasing numbers of fathers have been attending medical or day-care centers for young children, traditionally “reserved” for mothers and babies. Thus the professionals who work there are able to take an active part in the “co-construction of the fathers” by accompanying their emerging fatherhood. The Research-Action-Training approach used in partnership with the public health service (“Mother and Child Protection” in Paris) has proven to be a particularly interesting tool for modifying the routine found in day-care centers. Through the transfer of knowledge on fatherhood processes and new triadic models, it has led to improvements in the manner fathers are welcome but also babies and the whole family.     

Introductory Biology Courses: A Framework To Support Active Learning in Large Enrollment Introductory Science Courses

Active learning and research-oriented activities have been increasingly used in smaller, specialized science courses. Application of this type of scientific teaching to large enrollment introductory courses has been, however, a major challenge. The general microbiology lecture/laboratory course described has been designed to incorporate published active-learning methods. Three major case studies are used as platforms for active learning. Themes from case studies are integrated into lectures and laboratory experiments, and in class and online discussions and assignments. Students are stimulated to apply facts to problem-solving and to learn research skills such as data analysis, writing, and working in teams. This course is feasible only because of its organizational framework that makes use of teaching teams (made up of faculty, graduate assistants, and undergraduate assistants) and Web-based technology. Technology is a mode of communication, but also a system of course management. The relevance of this model to other biology courses led to assessment and evaluation, including an analysis of student responses to the new course, class performance, a university course evaluation, and retention of course learning. The results are indicative of an increase in student engagement in research-oriented activities and an appreciation of real-world context by students.     

Investigating learning from informal sources: Listening to conversations and observing play in science museums

The knowledge that pupils bring to science lessons can come from many sources, including some that are deliberately educative and some that contain scientific information, although education is not necessarily their primary purpose. Museums provide a useful setting to investigate the process of learning from informal sources; samples of data obtained from listening to groups of people as they interact with different types of exhibit in the British Museum (Natural History), and from systematic observation of pupils investigating phenomena in the Discovery Room at the Parc de la Villette, illustrate the information that can be obtained.

     

Effect of goal setting on the strategies used to solve a block design task

In this experiment we studied the effect of goal setting on the strategies used to perform a block design task called SAMUEL. SAMUEL can measure many indicators, which are then combined to determine the strategies used by participants when solving SAMUEL problems. Two experimental groups were created: one group was given an explicit, difficult goal and the other was not given a goal. The two groups were comparable in their average visual–spatial ability. The results indicated no goal effect on the strategies, defined in terms of the combined indicators. However, the goal did have an effect on some of the indicators taken alone (total problem-solving time, total viewing time, and model-viewing frequency) but this was true only for subjects with a low cognitive ability. These findings demonstrate that setting a goal can have an effect on some strategy indexes used to assess performance on a visual-intelligence design task. This research has implications for defining intelligence-test instructions and educational requirements in school.
