Essential Conditions for Technology-Supported,Student-Centered Learning: An Analysis of Student Experiences With Math Out Loud Using the ISTE Standards for Students

This article explores links between student experiences with technology-rich mathematics instruction and the ISTE Standards for Students. Research methods applied constructivist grounded theory to analyze data from student interviews against the ISTE Standards for Students to identify which elements of the design of this learning environment seemed to support the attainment of both mathematics content objectives and the ISTE Standards for Students. Researchers then identify guiding principles for the effective design of technology-supported, student-centered learning environments based on analysis of the results.

Scaffolding critical reasoning about history and social issues in multimedia-supported learning environments

This article advances a continuing line of research that investigates the potential of hypermedia resources and scaffolding for supporting problem-based social studies and developing critical reasoning. Our line of inquiry consists of a series of generative design experiments that informs problem-based curriculum development. Our findings suggest that expert guidance may be embedded into the learning environment to give students conceptual and strategic road maps that assist them in understanding the process of disciplined inquiry. However, our results also emphasize the difficulties in managing the cognitive challenges posed by ill-structured social problems and suggest limits to the embedded support that can be provided for complex thinking. Complex conceptual tasks may require spontaneous support that can only be provided by a skilled teacher. We suggest that embedded scaffolds may be used to support teachers by reducing the amount of spontaneous scaffolding they must do in an ill-structured environment and discuss other steps that might be taken to encourage problem-based inquiry. Support for this research has been provided by the Corporation for Public Broadcasting, Auburn University College of Education, and Auburn City Schools.     

Neonatal Stress Reactivity: Predictions to Later Emotional Temperament

To investigate the relations among popular measures of neonatal stress and their link to subsequent temperament, 50 full-term newborns from a normal care nursery were examined responding to a heelstick blood draw. Baseline and heelstick measures of behavioral state, heart period, vagal tone, and salivary cortisol were obtained. Recovery measures of behavioral and cardiac activity were also analyzed. Mothers completed Rothbart's Infant Behavior Questionnaire when their infants reached 6 months of age. Baseline vagal tone predicted cortisol in response to the heelstick, suggesting that baseline vagal tone reflects the infants' ability to react to stressors. Greater reactivity to the heelstick (more crying, shorter heart periods, lower vagal tone, and higher cortisol) was associated with lower scores on "Distress-to-Limitations" temperament at 6 months. This finding was consistent with the expectation that the capacity to react strongly to an aversive stimulus would reflect better neurobehavioral organization in the newborn. Recovery measures of cardiac activity approximated and were correlated with baseline measures indicating the strong self-righting properties of the healthy newborn. Finally, vagal tone and salivary cortisol measures were not significantly related, suggesting the importance of assessing both systems in studies of the ontogeny of stress-temperament relations.     

Developmentally appropriate parent training for families with young children

In an effort to explore the value and feasibility of teaching the principles behind developmentally appropriate practices to parents, 53 families with young children were studied. Parents were randomly assigned to participate or not participate in a three month-long, weekly, parent training program. Following completion of the program members of participating families were less likely to engage in conflict during a puzzle solving task than were members of nonparticipating families. Parents who participated were more likely to take a supportive leadership role and have age-appropriate expectations during a puzzle solving task than were nonparticipating parents. Children in participating families showed better social skills than children in nonparticipating families. Portions of the increase in social skills were related to reductions in family conflict and to the development of a task orientation that was more appropriately focused on process than outcome. Lower family conflict was also related to better gross motor skills in children.

Comparison of three instructional strategies in food and nutrition education: developing a diet plan for a diabetic case

This study examines the performance of dietitians-in-training on developing a diet plan for a diabetic patient either independently or after peer discussion. Participants (n?=?58) from an undergraduate program in food and nutrition were divided into two groups based on their prior knowledge before being randomly assigned into three conditions: (1) peer discussion with just-in-time information (JIT information), (2) peer discussion without JIT information), and (3) independent performers. The learners’ performance in the three conditions was analyzed. The results presented here describe the role of prior knowledge and JIT information across the conditions and the interaction of the two factors as well as the instructional implications of the findings.     

Statistical models for college admission and enrollment: A case study for a selective liberal arts college

In making admission decisions, selective colleges make choices that allow them to improve the quality of the college. Desired student attributes include leadership, noteworthy achievements and talents, and cultural and geographical diversity, as well as high academic performance. Since few applicants dominate in all these attributes, a delicate balancing act must be forged.In this study we construct probability models for college admissions and student enrollment. We have chosen a selective liberal arts college as a case study over a four-year period. In the first stage we estimate the probability of acceptance to the college for individual applicants. The logit model includes a number of academic factors as well as nonacademic components. In the second stage we estimate the probability of enrollment for an accepted student.The first stage results show that the actual outcome of the admissions decision does match the broader institutional goals of the college. However, in the second stage, the discrepancy between the acceptance and enrollment decisions frustrates the efforts of the institution to achieve its diversity goals and highlights the difficulty that admission officers have in targeting their efforts toward special groups of applicants.     

A scheme for assessing unmet educational needs: The American Samoa example

From 1960 onwards the U.S. Government set out to improve the schools in American Samoa. During the period 1971–75 educational leaders there carried out a series of studies of the islanders' educational needs in order to assess the suitability of existing learning goals and the degree to which they were being achieved. Approaches used were a community-opinion survey, a classroom-problems survey, an evaluation of the school system's specific instructional objectives, a program of standarized testing, a bi-lingual testing of academic achievement, a physical performance testing programme and a system of teacher-parent conferences and ratings of pupils progress. Ten critical unmet needs were identified: better command of English; greater mastery of Samoan language and culture; better opportunities to learn according to the pupil's individual abilities and background; better command of mathematics; increased vocational-education opportunities; improved physical-education skills; better command of social sciences; better command of health and science knowledge; more consistent school attendance, and better social skills. These needs were investigated in detail so that specific steps might be planned to fulfil them. The teacher/parent conferencing program, based on a Californian model, was a failure.

Zusammenfassung Seit 1960 ist die Regierung der USA bestrebt, das Schulwesen in Amerikanisch Samoa zu verbessern. In den Jahren 1971–75 haben führende Pädagogen eine Reihe von Untersuchungen über die Bildungsbedürfnisse der Inselbewohner durchgeführt, um festzustellen, ob die bestehenden Lernziele angemessen sind und inwieweit sie erreicht werden. Als Erhebungsinstrumente wurden benutzt: eine Meinungsumfrage in der Gemeinschaft, eine Erhebung über Unterrichtsprobleme, eine Bewertung der spezifischen Unterrichtsziele des Schulsystems, ein standardisiertes Testprogramm, ein Lehrer/Eltern-Konferenzsystem und Beurteilungswerte für Schülerleistungen. Es ergaben sich zehn kritische Erfordernisse: bessere Beherrschung der englischen Sprache; vertieftere Kenntnisse der Sprache und Kultur von Samoa; erweiterte Lernmöglichkeiten entsprechend den individuellen Fähigkeiten und der Herkunft der Schüler; bessere Mathematikbeherrschung; mehr Möglichkeiten zur Berufsausbildung; bessere Leibeserziehung; bessere Beherrschung der Sozialwissenschaften; mehr Kenntnisse über Gesundheitspflege und Naturwissenschaften; regelmässiger Schulbesuch; und besseres Sozialverhalten. Diese Erfordernisse wurden eingehend untersucht, damit spezifische Massnahmen zu ihrer Erfüllung geplant werden können. Das auf einem kalifornischen Modell basierende Lehrer/Eltern-Konferenzprogramm erwies sich als Misserfolg.

Résumé A partir de 1960 le Gouvernement des Etats-Unis commença à améliorer les écoles dans les Samoa Américaines. De 1971 à 1975, des dirigeants pédagogiques menèrent dans ce pays une série d'études sur les besoins en éducation des insulaires, de sorte à estimer si les buts d'apprentissage existants étaient en accord avec les besoins et et jusqu'à quel point ces buts étaient atteints. On aborda ceci par une étude de l'opinion de la communauté, une étude sur les problèmes de la salle de classe, une évaluation des objectifs spécifiques d'instruction du système scolaire, un programme de l'épreuve standardisé, une épreuve bilingue de performance académique, un programme d'épreuve de performance physique et un système de conférences entre parents et maîtres et d'évaluations du progrès des élèves. Dix besoins critiques non satisfaits furent identifiés: meilleurs maîtrise de l'anglais, maîtrise plus grande de la langue et de la culture des Samoa; meilleurs possibilités d'apprendre conformément aux capacités individuelles et au passé de l'élève; meilleure maîtrise des mathématiques, possibilités accrues d'éducation professionnelle; aptitudes améliorées pour l'éducation physique; meilleure maîtrise des sciences sociales; meilleure maîtrise des connaissances sur la santé et la science; fréquentation plus régulière de l'école et meilleures aptitudes sociales. Ces besoins ont été étudiés en détail, de sorte que des mesures spécifiques puissent être projetées pour résoudre ces besoins. Le programme de conférence entre parents et maîtres, basé sur un modèle californien, s'est avéré être une erreur.

     

Sleepy and hostile: The effects of REM sleep deprivation on shock-elicited aggression

Two studies were conducted to assess the effects of rapid eye movement (REM) sleep deprivation on shock-elicited aggression. REM deprivation periods of 0, 24, 48, and 72 h were used in the first study, while 48-, 72-, 96-, and 120-h periods were used in the second study. Both studies indicated that increases in REM deprivation (up to 96 h) resulted in increases in the number of aggressive responses. A decrease was shown by the 120-h group. A drive-energization or motivational-effects model is suggested.     

A program for excellence in physics and physical science teaching

Conclusion It seems reasonable to conclude that the impact of these projects has been extensive and that we have met our basic objectives regarding the improvement of science education for the target teachers and students. The long-term goal of improved scientific literacy of at least a part of the citizens of this country and world can only be assessed by some form of longitudinal study that is beyond the scope and funding for these projects. But our assessment of what has been accomplished in the short term efforts seems to indicate very positive gains in those areas of knowledge, confidence, and pedagogical capability that we believe will enable the participants to make contributions to the improvement of scientific literacy for the students with whom they work. In short, we believe we have had two successful and worthwhile programs that have been useful and effective.
