Investigating the Influence of a Mixed Face-to-Face and Website Professional Development Course on the Inquiry-Based Conceptions of High School Science and Mathematics Teachers

The purposes of this study are to report the influences of a mixed delivery professional development [PD] course involving face-to-face classes and the mentoring assisted inquiry-based teaching [MAIT] website that addressed the conceptual change and self-efficacy of high school mathematics and science teachers’ conceptions of inquiry-based teaching. Twenty-five in-service high school science and mathematics teachers participated in a 9 weeks, 4 h per week PD course. Data collection included the pre-post Inquiry Teaching Efficacy Questionnaire [ITEQ], teachers’ reflective journals posted on the MAIT website, teachers’ assignments requested by the course instructor, and follow-up teachers’ interviews. Findings revealed that both mathematics and science teachers’ conceptions of inquiry teaching show significant improvements after the course. The mixed delivery PD course had the same influence on science and mathematics teachers. The authentic video clips and lesson plans provided on the MAIT website and the specific feedback toward teachers’ performance are the main factors that shaped teachers’ inquiry-based teaching conceptions.     

Museum Experience — a Resource for Science Teacher Education

In this study, the researcher included an extensive science museum experience for the pre-service secondary science teachers within a teaching methods course to enhance their learning to teach science. The extensive museum experience covered four aspects: the visit, discussion with museum educators, the development of lesson plans, and practising teaching in the science museum. Twenty-one pre-service science teachers attended this course. Qualitative methods were used for data collection and analysis. The data sources included field notes, reports, diaries, and interviews. The findings show that this course connecting museum resources and context had created a novel situation for pre-service science teachers to learn how to teach science. The discourses with the museum educators also provided them with innovations in education beyond the gains from traditional teacher education. Through developing and practising teaching activities, they improved their understanding of the meanings and effective ways to use museum resources in science teaching. Pre-service science teachers reported that getting feedback from peers and observing modeling teaching was helpful. This course provided an alternative way to view how scientific activities were developed for junior high students. In general, the use of museum settings provides a new profile of learning and teaching course for pre-service science teachers in Taiwan. Based on the findings, this study makes suggestions for those science teacher educators who would like to use science museum resources and contexts to nurture prospective science teachers.     

An Outreach Support Group for International Students

International students often face challenges in adjusting to their new environment without the use of local supports such as counseling. This article suggests how universities can form an outreach support group that encourages the participation of international students by minimizing the stigma associated with using mental health services and by addressing relevant practical and emotional issues that international students face.

Health benefits of Kung Fu: A systematic review

Abstract

The Chinese martial arts (Kung Fu) have existed for centuries and are generally accepted as being beneficial for health without much empirical data. The aim of this systematic review was to assess the health effects of “hard” Kung Fu styles by performing electronic and manual searches of the literature. The aspects of health and the Kung Fu style examined varied between most studies; in some cases, the martial art group consisted of practitioners of other martial art styles also. Of 2103 references identified, only nine papers were eligible and reviewed. All were observational studies, observing a range of health aspects possibly related to Kung Fu training or performance. Our findings suggest that there is no evidence that Kung Fu practice is associated with the prevention or treatment of any health condition. However, as a moderate- to high-intensity form of aerobic exercise, it may confer benefits similar to those attributed to other aerobic training modalities. However, this hypothesis remains to be tested in clinical trials. Physiological benefits (e.g., aerobic capacity and bone density) may be associated with long-term Kung Fu practice. Future research in this area should adopt experimental designs, clearly identifying eligibility criteria, testing and training protocols, and include health-related outcomes and documentation of adverse events, to advance knowledge in this field.
