Exploring strategies for online teaching and learning

This paper explores various strategies for creating engaging online learning environments. It describes a framework which identifies and distinguishes between the critical elements needed in the design of online learning: the content of the course, the learning activities and the learning supports. It demonstrates through practical examples how each of these elements can be manipulated in deliberate ways to influence learning processes and outcomes. The paper supports the notion that online courses are best when they arc engineered to take advantage of the learning opportunities afforded by the online technologies, rather than being used as supplements to conventional teaching programs.     

Teaching Statistics in US — An Alien's s-eye View

This article discusses the author's initial experience of teaching statistics in an American university, and the sort of way he thinks the subject should be taught. (Specifically, he looks at the assumption of normality, and indicates how conventional treatment in the area of hypothesis testing might be modified.) His comments primarily apply to elementary service courses, and particularly to those provided for business students.     

Three studies of factors affecting the attitudes of blacks and females toward the pursuit of science and science-related careers

This study involved the development of an instrument, the Science Career Predictor Scale (SCPS), which assesses seven factors thought to be involved with science career choices: teacher/counselor encouragement, participation in science-related hobbies and activities, academic self-image, science-related career interest, parental encouragement and support, the perceived relevance of mathematics and science, and mathematics and science ability. This instrument was administered to a sample of 522 middle and high school students, and a sample of 185 students from an historically black university, and the effects of such factors as sex, race, personal acquaintance with a scientist, and type of community (rural or urban) on the above-mentioned variables were ascertained using a multivariate analysis of covariance with age as the covariate. A separate study on a sample of 81 high school students looked at race and gender differences in critical thinking abilities as measured by the Watson-Glaser Critical Thinking appraisal, and how these abilities correlated with scores on the Science Career Predictor Scale. These studies produced several significant findings. Female subjects did produce significantly lower scores on the career interest factor. Black students actually had significantly higher science-career preference scores than their white counterparts. However, blacks scored significantly lower on the measure of critical thinking ability. Across both races and both sexes, however, the major factor affecting science-related career decisions appears to be personal contact with a scientist. The implications of these findings are discussed, along with possible strategies for increasing the participation of these groups in science.     

Safe Schools/Healthy Students initiative: Pinellas County,Florida

The Safe Schools/Healthy Students (SS/HS) Initiative in Pinellas County, FL, emerged as a part of a broader local effort to implement creative educational and mental health programs to support children and families. This initiative focused on capacity building, prevention, and intervention efforts and comprehensive evaluation to address the barriers to learning and enhance healthy development. This article describes Pinellas County's plan, and highlights the instrumental roles played by school psychologists, which included grant writing, program and resource coordination, clinical services, program evaluation, staff training, parent advocacy, and steering committee membership. Promising outcomes and generalization of these findings to other communities is also discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 489–501, 2003.     

Exploring Spanish pre-service teachers’ talk in relation to ICT: balancing different expectations between the university and practicum school

Information and communications technology (ICT) now plays a prominent role in pre-service teacher education programmes across the globe. Despite this emphasis, research indicates that pre-service teachers’ use of ICT is often less than expected, even though they express positive opinions of its benefits. This study aimed to explore pre-service teachers’ views of ICT and consider the function of their expressed opinions. This longitudinal study, using one-to-one semi-structured interviews, was conducted with pre-service teachers on entry and on completion of a one-year Masters programme in Spain. The pre-service teachers held quite traditional views of teaching and learning, presenting teaching in an either–or manner – either ICT supported or non-ICT supported. They also spoke positively about ICT while simultaneously expressing reservations about it. The article argues that these contradictory positions may be a result of the need to navigate two competing environments, the higher education institution and the practicum school, where expectations of ICT use may differ. The article explores this performative function of their talk.     

Long-term inhibition of Na+/H+ exchange attenuates cardiac remodeling after myocardial infarction in rats

Objective: In addition to pH regulation, Na⁺/H⁺ exchange (NHE) has been shown to facilitate cell growth and proliferation. However, the effects of long-term inhibition of Na⁺/H⁺ exchange on cardiac structural and functional remodeling post myocardial infarction (MI) are still controversial. The present study was therefore carried out to further investigate the effects of long-term treatment with cariporide, a specific inhibitor of NHE-1, on cardiac remodeling after MI in rats; Methods: Male Wistar rats that underwent coronary ligation were randomly selected for cariporide treatment starting 6 h after induction of MI or no treatment. Treatment was continued up to 6 weeks post MI, after which, the arterial, venous and left ventricular catheters were chronically implanted. Twenty-four h later, after hemodynamic signals were recorded in conscious rats, they were sacrificed and hearts were taken out for morphological examinations; Results: Cariporide treatment decreased the heart weight and heart weight to body weight ratio (bothP<0.05), decreased left ventricular end-diastolic pressure (P<0.001), improved myocardial contractility (dP/dt _max) (P<0.05) and tended to increase the survival of treated rats compared to that of untreated infarct rats; Conclusion: The results of the present study indicate that the long-term inhibition of NHE with cariporide can attenuate cardiac structural remodeling and improve left ventricular dysfunction in infarcted rats, and suggest that Na⁺/H⁺ exchange inhibition could be an effective therapeutic strategy for myocardial infarction-induced heart failure.     

Schulformen als differenzielle Lernmilieus Institutionelle und kompositionelle Effekte auf die Leistungsentwicklung im Fach Franz?sisch

Auf der Basis von zwei repr?sentativen Schülerstichproben der Schweizer Kantone Wallis (N = 926) und Fribourg (N = 778), die w?hrend der 8. Jahrgangsstufe im Fach Franz?sisch als Fremdsprache unterrichtet wurden, geht der vorliegende Beitrag der Frage nach, ob Schülerinnen und Schüler je nach besuchtem Bildungsgang unterschiedliche Fortschritte in der Entwicklung ihrer Fachleistungen machen. Von besonderem Interesse ist dabei, ob und in welchem Ausma? die Zusammensetzung der Schülerschaft (Kompositions-effekte) und m?glicherweise auch institutionell differierende didaktische und curriculare Angebote zwischen den Bildungsg?ngen (Institutionseffekte) als lernmilieupr?gende Faktoren von Bedeutung für die Entwicklung der Fachleistungen sind. In Mehrebenenanalysen zeigten sich auch nach Kontrolle der individuellen Eingangsvoraussetzungen (einschlie?lich des Vorwissens) bedeutsame Unterschiede in den Lernzuw?chsen an den verschiedenen Bildungsg?ngen. Die weiteren Analysen lassen darauf schlie?en, dass sowohl von kompositionellen als auch institutionellen Effekten auf die Leistungsentwicklung auszugehen ist.     

Embedding CETLs in a performance‐oriented culture in higher education: Reflections on finding creative space

This article offers insight into the realization of the Higher Education Funding Council for England's vision for Centres for Excellence in Teaching and Learning (CETLs) as catalysts for change. Two CETLs, the Centre for Interprofessional e‐Learning (CIPeL) and the Surrey Centre for Excellence in Professional Training and Education (SCEPTrE), provide illustrative cases of two similar but different change initiatives. CETLs might be expected to embody and inspire creativity in teaching and learning yet they are embedded in institutions where activities are increasingly shaped by the discourse of performativity. Findings from the two case studies, which focus on similar schemes designed to promote staff involvement in creative projects, challenge the suggestion that creativity is stifled in a performative context.     

eVALUate: an evaluation instrument for measuring students’ perceptions of their engagement and learning outcomes

In the current climate in Australian higher education, quality assurance in university teaching is a priority. In particular, the introduction of the Learning and Teaching Performance Fund (LTPF) has refocused attention on universities’ internal student evaluation survey instruments. This paper reports the development, validation and implementation of a new unit survey instrument which prompts students to reflect on what helps their achievement of unit learning outcomes, and to report their levels of motivation, engagement and overall satisfaction with a semester‐long course or unit of study. The instrument (eVALUate) was created from precepts reported in the research literature, current practices in evaluating teaching, and sound quality assurance practices appropriate to a university outcomes‐focused education paradigm.     

Prosocial and Aggressive Behavior: A Longitudinal Study

Developmental theorists have made strong claims about the fundamental prosocial or aggressive nature of the human infant. However, only rarely have prosocial behavior and aggression been studied together in the same sample. We charted the parallel development of both behaviors from infancy to childhood in a British community sample, using a two-construct, multimethod longitudinal design. Data were drawn from the Cardiff Child Development Study (CCDS), a prospective longitudinal study of a volunteer sample of parents and their firstborn children. A sample of 332 mothers was recruited from National Health Service (NHS) prenatal clinics and general practice clinics in Wales, UK, between Fall of 2005 and Summer of 2007. Potential participants represented the full range of sociodemographic classifications of neighborhoods. Participating families were divided about equally between middle- and working-class families, were somewhat more likely to have sons than daughters, and the majority (90%) were in a stable partnership. In response to standard categories recommended for use in Wales at the time, the majority (93%) of mothers reported themselves as Welsh, Scottish, English, or Irish; most others named a European or South Asian nationality. Of the 332 families agreeing to participate, 321 mothers (M_age = 28 years) and 285 partners (M_age = 31 years) were interviewed during the pregnancy and 321 of the families contributed data at least once after the child's birth. After an initial home visit at 6 months, data collection occurred in four additional waves of testing when children's mean ages were approximately 1, 1.5, 2.5, and 7 years. Data collection alternated between family homes and Cardiff University. Of those families seen after the child's birth, 89% were assessed at the final wave of testing. Data collection ended in 2015. Methods included direct observation, experimental tasks, and collection of reports from mothers, fathers, other relatives or family friends, and classroom teachers. Interactions with a familiar peer were observed at 1.5 years. Interactions with unfamiliar peers took place during experimental birthday parties at 1 and 2.5 years. At 7 years, parents were interviewed, parents and teachers completed questionnaires, and the children engaged in cognitive and social decision-making tasks. Based on reports from parents and other informants who knew the children well, individual differences in both prosocial behavior and aggression were evident in children. Both types of behavior showed stability across the second and third years. The association between prosocial behavior and aggression changed over time: at 1.5 years, they were not significantly related (the association approached zero), but they became negatively correlated by 3 years. Different patterns were seen when children played with familiar versus unfamiliar peers. At 1.5 years, when children were observed at home with a familiar peer, prosocial behavior and aggression were unrelated, thus showing a pattern of results like that seen in the analysis of informants' reports. However, a different pattern emerged during the experimental birthday parties with unfamiliar peers: prosocial behavior and aggression were positively correlated at both 1 and 2.5 years, contributing to a general sociability factor at both ages. Gender differences in prosocial behavior were evident in informants' reports and were also evident at the 1-year (though not the 2.5-year) birthday parties. In contrast, gender differences in both prosocial behavior and aggression were evident by 7 years, both in children's aggressive decision-making and in their parents' and teachers' reports of children's aggressive behavior at home and school. By age 7, children's aggressive decision-making and behavior were inversely associated with their verbal skills, working memory, and emotional understanding. Some children had developed aggressive behavioral problems and callous-unemotional traits. A few (12%) met diagnostic criteria for conduct disorder or oppositional-defiant disorders, which had been predicted by early angry aggressiveness and lack of empathy for other people. Taken together, the findings revealed a gradual disaggregation of two ways in which children interact with other people. Individual differences in both prosocial behavior and aggression revealed continuity over time, with gender differences emerging first in prosocial behavior, then in aggression. Restrictions in the participant sample and the catchment area (e.g., all were first-time parents; all were drawn from a single region in the United Kingdom) mean that it is not possible to generalize findings broadly. It will be important to expand the study of prosocial behavior and aggression in other family and environmental contexts in future work. Learning more about early appearing individual differences in children's approaches to the social world may be useful for both educational and clinical practice.
