Improving science teachers' conceptions of nature of science: a critical review of the literature

This paper aimed to review, and assess the 'effectiveness' of the attempts undertaken to improve prospective and practising science teachers' conceptions of nature of science (NOS). The reviewed attempts could be categorized into two general approches: implicit and explicit. Implicit attempts utilized science process-skills instruction or engagement in science-based inquiry activities to improve science teachers' conceptions of NOS. To achieve the same goal, explicit attempts used instruction geared towards various aspects of NOS and/or instruction that utilized elements from history and philosophy of science. To the extent that teachers' NOS conceptions were faithfully assessed by the instruments used in the reviewed studies, the explicit approach was relatively more effective in enhancing teachers' views. The relative ineffectiveness of the implicit approach could be attributed to two inherent assumptions. The first is that developing an understanding of NOS is an 'affective', as compared to a 'cognitive', learning outcome. The second ensuing assumption is that learners would necessarily develop understandings of NOS as a by-product of engaging in science-realated activities. However, despite the relative 'effectiveness' of the explicit approach, much is still required in terms of fostering among science teachers 'desired' understandings of NOS. The paper emphasizes that explicitness and reflectivness should be given prominence in any future attempts aimed at improving teachers' concepts of NOS.     

Family Fun Nights: Collaborative Parent Education Accessible for Diverse Learning Abilities

Quality early childhood education programs have a responsibility to provide enriched educational services to preschool students paired with parent support, education, and outreach. Pearl Buck Preschool, a non-profit organization devoted to the delivery of preschool services for children of parents with intellectual disabilities or learning difficulties, created a unique parent program titled Family Fun Night. This six-session series was developed with a strengths-based, collaborative framework and was connected to the Program-wide Positive Behavioral Interventions and Supports implementation in the preschool. The following paper discusses the development, facilitation, implementation, logistics, and assessment of the Family Fun Night series. Barriers to implementation are also discussed.     

Perspectives on Conceptualizing Developmentally Appropriate Sexuality Education

Despite recognition of the importance of a developmentally appropriate approach to sexuality education, there is little direct guidance on how to do this. This study employed in-depth interviews with experienced sexuality educators and developers of sexuality education materials to identify how this concept is understood and applied in the field. Developmentally appropriate sexuality education was conceptualized consistently across interviews to include (a) addressing developmentally relevant topics, (b) adapting content to cognitive development, (c) accommodating developmental diversity, and (d) facilitating the internalization of sexual health messages. However, these views fell short of incorporating the breadth of knowledge offered by adolescent development research.     

Design,implementation, and evaluation of an innovative anatomy course

Starting in 2004, a medical school gross anatomy course faced with a 30% cut in hours went through an extensive redesign, which transformed a traditional dissection course into a course with a clinical focus, learning societies, and extensive on‐line learning support. Built into the redesign process was an extensive and ongoing assessment process, which included student focus groups, faculty development, surveys, and examinations. These assessments were used formatively, to enhance the course from year to year, and summatively, to determine how well the course was meeting the new learning objectives. The assessments from focus groups and faculty development prompted changes in support structures provided to students and the training and preparation of faculty. Survey results showed that, after student satisfaction declined the first year, satisfaction increased steadily through the fourth iteration as the course gained acceptance by students and faculty alike. There was a corresponding increase in the performance of students on course examinations. An additional examination given to students one and a half and three years after their anatomy course ended demonstrated the redesigned course's long‐term effectiveness for retaining anatomical knowledge and applying it to clinical cases. Compared to students who took the original course, students who took the shorter, more clinical course performed as well, or better, on each section of the examination. We attribute these positive results to the innovative course design and to the changes made based on our formative assessment program. Anat Sci Educ, 2010. © 2010 American Association of Anatomists.
