Narrative accounts of US teachers' collaborative curriculum making in a physical education department

Through the use of narrative inquiry, this research study explores the collaborative curriculum making experiences of six teachers (three males; three females) in one physical education (PE) department in an urban middle school in the U.S. Collaboration; as defined in this work, this has to do with teachers’ voluntary interactions and their shared decision making in support of common goals. Where curriculum making is concerned, it refers to interactions between and among the four commonplaces of curriculum (teacher, learner, subject matter, milieu). The paper features the perspectives of the department head (female), experienced teachers (male and female) and teachers new to the profession (male and female). The narrative accounts of the individual teachers are set against the backdrop of the PE department with which they identify and within the storied history of the school in which they work. The story constellations representational form conveys the interrelatedness of the narratives and instantiates the teachers’ experiences of collaborative curriculum making. In the final analysis, this research enterprise makes a major contribution to the study of PE as well as to education generally. To date, no inquiries have focused on the collaborative curriculum making of teachers lodged in a PE department in one school context, despite collaborative curriculum making most closely reflecting how PE teachers typically approach the teaching task due to shared classrooms/gymnasiums/fields and the communal use of equipment.     

Thermally multiplexed polymerase chain reaction

Amplification of multiple unique genetic targets using the polymerase chain reaction (PCR) is commonly required in molecular biology laboratories. Such reactions are typically performed either serially or by multiplex PCR. Serial reactions are time consuming, and multiplex PCR, while powerful and widely used, can be prone to amplification bias, PCR drift, and primer-primer interactions. We present a new thermocycling method, termed thermal multiplexing, in which a single heat source is uniformly distributed and selectively modulated for independent temperature control of an array of PCR reactions. Thermal multiplexing allows amplification of multiple targets simultaneously—each reaction segregated and performed at optimal conditions. We demonstrate the method using a microfluidic system consisting of an infrared laser thermocycler, a polymer microchip featuring 1 μl, oil-encapsulated reactions, and closed-loop pulse-width modulation control. Heat transfer modeling is used to characterize thermal performance limitations of the system. We validate the model and perform two reactions simultaneously with widely varying annealing temperatures (48 °C and 68 °C), demonstrating excellent amplification. In addition, to demonstrate microfluidic infrared PCR using clinical specimens, we successfully amplified and detected both influenza A and B from human nasopharyngeal swabs. Thermal multiplexing is scalable and applicable to challenges such as pathogen detection where patients presenting non-specific symptoms need to be efficiently screened across a viral or bacterial panel.     

Mindfulness‐Based Awareness and Compassion: Predictors of Counselor Empathy and Anxiety

Mindfulness‐based awareness and compassion were examined as predictors of empathy and anxiety among 152 master's‐level counseling interns. Results of hierarchical multiple regression analysis supported that awareness and compassion differentially contributed to explaining the variance in counselor empathy and anxiety. Implications for counselor education are discussed.     

When worlds collide: identity,culture and the lived experiences of research when ‘teaching-led’

This article presents detailed findings from the qualitative or interpretive phase of a mixed-methods case study focusing on the professional identities and lived experiences of research among six lecturers working in different capacities across the field of education in a ‘teaching-led’ higher education institution. Building upon the quantitative phase published earlier in this journal, factors both facilitating (e.g. research infrastructure, support for doctoral study) and constraining (e.g. time, space, workload, critical mass, ‘practitioner bond professionalism’, ‘organisational socialisation’, networks, roles and responsibilities, power relationships) research activity are identified. These are considered in the context of an institution often recruiting staff with ‘non-traditional’ backgrounds from within ‘the professions’ (e.g. from schools and colleges without doctorates) looking to become more ‘research-informed’ and establish a more vibrant and sustainable research culture. Recommendations for further development focus on ‘identity transitions’ and ‘cultural transformation’, emphasising the importance of research leadership and its distribution throughout the organisation. With current trends towards the apparent intensification and prioritisation of research activity over teaching, findings are considered particularly important for institutions of a similar nature to the one described here, for education departments in larger institutions also on similar journeys, and in light of an anticipated increase in demand for research activity arising from the expansion of higher education provision in further education and the private sector, where recruitment from within ‘the professions’ to teach across ‘vocational’ programmes is common.     

Improved Appreciation of Mathematics Through an IBL Liberal Arts Mathematics Course

Abstract

The author has taught an inquiry-based liberal arts mathematics class using the text “The Heart of Mathematics: An Invitation to Effective Thinking” by Edward B. Burger and Michael Starbird a total of 20 times since Spring 2001. The students in this class have almost all been in non-technical majors and many started the semester with negative or ambivalent attitudes toward mathematics based on their prior experiences. The author has gathered responses from students in this class that illustrate significant changes in their attitudes towards mathematics during the course. In particular, the responses gathered at the end of the semester are often eloquent about understanding the great ideas of mathematics that students confronted in this course and about seeing many more and varied connections between mathematics and the “real world” than they had previously realized existed.     

Re-Entering the Sporting World: China's Sponsorship of the 1963 Games of the New Emerging Forces (GANEFO)

Prior to the 2008 Olympics, China's most sustained support of an international multi-sport event came in 1963 when it contributed significantly to the financing of and then dominated the medals table at the inaugural Games of the New Emerging Forces (GANEFO), held in Jakarta. GANEFO is a singular moment through which to understand politics and sport in the 1960s. This article is a consideration of China's role in GANEFO, and the West's response to China's involvement. It explores the ways in which China used the event to navigate issues of international and regional geopolitics, and considers the diplomatic and sporting corridors within which GANEFO resonated. GANEFO was a platform through which geopolitical tensions were revealed, and China engaged in propaganda campaigns directed at the West and positioned itself to win allies among the decolonising countries of Asia and Africa – astride the artificial boundary that separated the Second and Third Worlds. China's interest in and the West's response to GANEFO reflected the ways in which anti-communist Cold War politics were conflated with racialised, post-colonial discourses and tension between Second World powers.     

Preschoolers modulate contrastive inferences during online language comprehension

This study examined 4- and 5-year-olds' incremental interpretation of size adjectives, focusing on whether contrastive inferences are modulated by speaker behavior. Children (N = 120, 59 females, mostly White, tested between July, 2018 and August, 2019) encountered either a conventional or unconventional speaker who labeled objects in a correspondingly typical or atypical way. Critical utterances contained size adjectives (e.g., “Look at the big duck”). With conventional speakers, gaze measures indicated that children rapidly used the adjective to differentiate members of a contrasting pair, indicating that even 4-year-olds derive contrastive inferences. With unconventional speakers, contrastive inferences were delayed in processing. The findings demonstrate that preschoolers adjust their use of pragmatic cues when presented with evidence disconfirming their default assumptions about a speaker.     

Four requirements for digital case study libraries

In education, case studies have been employed as a major pedagogical means to engage students with realistic materials and practical problems. The usefulness and success of case studies have been documented in literature. In this paper, we move the case study and its technical affordance a step further toward more authentic or realistic learning and toward communities of practice. Drawing on current intellectual achievement in education, developmental psychology and computer-supported collaborative learning, this paper proposes four requirements for interactive case study libraries, focusing on authentic learning, social interaction, resource accumulation, and communities of practice. With a usability engineering case study library as an example, we discuss design concerns derived from these requirements as well as its use in practice.
