How Framing Climate Change Influences Citizen Scientists’ Intentions to Do Something About It

How we communicate the dangers of climate change may influence attitudes, intentions, and behaviors. Here we test two pairs of positive and negative framing statements with North American citizen scientists interested in gardening and birdwatching. Mentioning dangers for humans did not increase participants’ interest in taking personal action on climate change, but mentioning dangers for birds was highly effective. Highlighting the positive collective impacts of small behavioral changes also increased participants’ interest in taking personal action. These results suggest that while some dire messages are ineffective, those evoking concern for target species of significance to the learners may be as successful as positive messages.     

Mapping Changes in Science Teachers’ Content Knowledge: Concept Maps and Authentic Professional Development

Two studies were conducted to examine content knowledge changes following 2 weeks of professional development that included scientific research with university scientists. Engaging teachers in scientific research is considered to be an effective way of encouraging knowledge of both inquiry pedagogy and content knowledge. We used concept maps with two cohorts of teachers to assess changes in science teacher knowledge. In study 1, 34 teachers developed pre- and post-concept maps in one of the nine different content areas. A repeated measures analysis of six quantitative scores showed statistically significant increases in knowledge representation. Quantitative and qualitative scoring methods indicate that concept maps are effective for assessing teacher knowledge gains from professional development. Study 2 replicated the results with 24 teachers and provided further information about how knowledge changes.     

Toward Measuring Instructional Interactions “At-Scale”

This study explores two approaches to directly measuring the quality of instruction: teachers' assignments with student work and focused lesson observations. The technical quality and potential feasibility of these approaches for measuring instruction in large numbers of classrooms are compared within two different content areas (reading comprehension and mathematics). Generalizability and decision studies determined the optimal number of observations and assignments needed to obtain a reliable measure of a teacher's practice, and the association of these direct measures of instructional quality with student achievement was estimated. For both content areas, four assignments assessed by two raters yielded a reliable estimate of quality and as few as two observations yielded a reliable estimate of quality when teachers complied with the requirements of the research. The quality of observed instruction and teachers' assignments differentially predicted gains in students' achievement on the Stanford Achievement Test within each content area. The implications for measuring instruction “at-scale” in different content areas are discussed.     

Researcher Study Thyself: AERA Participants' Speaking Times and Turns by Gender

This research compares speaking times and turns of female and male presenters and audience members at the 2000 Annual Meeting of the American Educational Research Association (AERA). In their presentations, males spoke longer than females, but the differences were not statistically significant. They spoke significantly longer than females, however, when posing questions or comments during open discussions, and they made a significantly greater number of responses to these questions and comments. Some chairs were inconsistent in monitoring allotted speaking times. Females' participation was lower in less-structured situations, such as open discussions and co-presented papers, than in settings with greater structure.     

Influence of body composition on physiological responses to post-exercise hydrotherapy

This study examined the influence of body composition on temperature and blood flow responses to post-exercise cold water immersion (CWI), hot water immersion (HWI) and control (CON). Twenty-seven male participants were stratified into three groups: 1) low mass and low fat (LM-LF); 2) high mass and low fat (HM-LF); or 3) high mass and high fat (HM-HF). Experimental trials involved a standardised bout of cycling, maintained until core temperature reached 38.5°C. Participants subsequently completed one of three 15-min recovery interventions (CWI, HWI, or CON). Core, skin and muscle temperatures, and limb blood flow were recorded at baseline, post-exercise, and every 30 min following recovery for 240 min. During CON and HWI there were no differences in core or muscle temperature between body composition groups. The rate of fall in core temperature following CWI was greater in the LM-LF (0.03 ± 0.01°C/min) group compared to the HM-HF (0.01 ± 0.001°C/min) group (P = 0.002). Muscle temperature decreased to a greater extent during CWI in the LM-LF and HM-LF groups (8.6 ± 3.0°C) compared with HM-HF (5.1 ± 2.0°C, P < 0.05). Blood flow responses did not differ between groups. Differences in body composition alter the thermal response to post-exercise CWI, which may explain some of the variance in the responses to CWI recovery.     

Bridging Education and Practice With a Competency-Based Learning Contract

ABSTRACT

Field work programs have a substantial responsibility for providing support and gatekeeping functions while ensuring an educational experience that allows students to master the nine holistic, multidimensional social work accreditation competencies. With additional emphasis on field as a “signature pedagogy,” field directors are tasked with finding placements that can support these explicit competencies. Through the utilization of a learning contract that combines the Council on Social Work Education Educational Policy and Accreditation Standards competencies (including component behaviors) students and supervisors can begin to discuss their joint progress on meeting each of these prior to the final evaluation. This process will ensure that students have demonstrated the necessary outcomes to become a generalist social work practitioner.     

Staff Development Programmes in Universities: A Curriculum Proposal

This paper suggests the basis for a successful staff development programme in universities using a “concerns‐based” model. It argues for a deliberative approach to staff development where the concerns of academic staff determine the strategies adopted. Such an approach is multi‐dimensional and dynamic. By incorporating a continuous arid deliberate reflective process it can accommodate a wide range of strategies and adaptations as needs change and develop. In these terms the traditional staff development programme based on a narrow “objectives” model is rejected because it fails to take contextual factors adequately into account and is unable to adapt continuously to changing circumstances. The argument is illustrated by reference to a programme based on this model at Massey University, Palmerston North, New Zealand.     

Two- to eight-month-old infants' perception of dynamic auditory-visual spatial colocation

From birth, infants detect associations between the locations of static visual objects and sounds they emit, but there is limited evidence regarding their sensitivity to the dynamic equivalent when a sound-emitting object moves. In 4 experiments involving thirty-six 2-month-olds, forty-eight 5-month-olds, and forty-eight 8-month-olds, we investigated infants' ability to process this form of spatial colocation. Whereas there was no evidence of spontaneous sensitivity, all age groups detected a dynamic colocation during habituation and looked longer at test trials in which sound and sight were dislocated. Only 2-month-olds showed clear sensitivity to the dislocation relation, although 8-month-olds did so following additional habituation. These results are discussed relative to the intersensory redundancy hypothesis and work suggesting increasing specificity in processing with age.     

ENACTED TYPES OF ALGEBRAIC ACTIVITY IN DIFFERENT CLASSES TAUGHT BY THE SAME TEACHER

The aim of this study was to examine how teachers enact the same written algebra curriculum materials in different classes. The study addresses this issue by comparing the types of algebraic activity (Kieran, 2004) enacted in two 7th grade classes taught by the same teacher, using the same textbook. Data sources include lesson observations and an interview with the teacher. The findings show that students in the two classes were offered somewhat different algebraic experiences. At one school, more emphasis was placed on global/meta-level activities (activities that are not exclusive to algebra and suggest general mathematical processes), whereas at the other school, more emphasis was placed on transformational activities (“rule-based” algebraic activities). Analysis of the sources of the differences related to the ways in which the teacher used and enacted the curriculum materials in the two classes revealed that these were linked to the teacher’s attempts to be attentive to the students in the class and to the nature of the students’ work.
