Just do it? impact of a science apprenticeship program on high school students' understandings of the nature of science and scientific inquiry

The purpose of this study was to explicate the impact of an 8‐week science apprenticeship program on a group of high‐ability secondary students' understandings of the nature of science and scientific inquiry. Ten volunteers (Grades 10–11) completed a modified version of the Views of Nature of Science, Form B both before and after their apprenticeship to assess their conceptions of key aspects of the nature of science and scientific inquiry. Semistructured exit interviews provided an opportunity for students to describe the nature of their apprenticeship experiences and elaborate on their written questionnaire responses. Semistructured exit interviews were also conducted with the scientists who served as mentors for each of the science apprentices. For the most part, students held conceptions about the nature of science and scientific inquiry that were inconsistent with those described in current reforms. Participating science mentors held strong convictions that their apprentices had learned much about the scientific enterprise in the course of doing the science in their apprenticeship. Although most students did appear to gain knowledge about the processes of scientific inquiry, their conceptions about key aspects of the nature of science remained virtually unchanged. Epistemic demand and reflection appeared to be crucial components in the single case where a participant experienced substantial gains in her understandings of the nature of science and inquiry. © 2003 Wiley Periodicals, Inc.

Perception,communication and educational research: A transactional view

Summary We have not presented a transactional theory, since, so far as we know, there is no one such theory to present. Instead, we have outlined some transactional viewpoints which we consider potentially useful in audiovisual communication, learning resources development, and research in these areas. We have suggested some implications and advantages of transactional assumptions.     

Acupuncture for treating polycystic ovary syndrome: guidance for future randomized controlled trials

Objective

To provide guidance for future randomized controlled trials (RCTs) based on a review concerning acupuncture for treating polycystic ovary syndrome (PCOS).

Methods

A comprehensive literature search was conducted in October 2015 using MEDLINE, EMBASE, SCISEARCH, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Menstrual Disorders and Subfertility Group trials register, Allied and Complementary Medicine (AMED), China National Knowledge Infrastructure (CNKI), and the Wanfang databases. RCTs comparing either acupuncture with no/sham/pharmacological intervention or a combination of acupuncture and conventional therapy with conventional therapy in the treatment of PCOS were included in this review. A quality evaluation was performed for each of the included studies.

Results

Thirty-one RCTs were included in the review and were divided into four categories according to the type of intervention used in the comparator or control group. Menstrual frequency, hormones, anthropometrics, insulin sensitivity, blood lipids, and fertility were used as the main measurements to assess the effects of acupuncture on the patients with PCOS. Thirty trials, except for one, showed an improvement in at least one of the indicators of PCOS after acupuncture treatment. However, normalizing the methodological and reporting format remains an issue.

Conclusions

Based upon this review of current clinical trials concerning acupuncture for treating PCOS, we provide guidelines for better clinical trial design in the future.

     

Confronting prospective teachers' ideas of evolution and scientific inquiry using technology and inquiry‐based tasks

This study addresses the need for research in three areas: (1) teachers' understandings of scientific inquiry; (2) conceptual understandings of evolutionary processes; and (3) technology‐enhanced instruction using an inquiry approach. The purpose of this study was to determine in what ways The Galapagos Finches software–based materials created a context for learning and teaching about the nature of scientific knowledge and evolutionary concepts. The research used a design experiment in which researchers significantly modified a secondary science methods course. The multiple data sources included: audiotaped conversations of two focus pairs of participants as they interacted with the software; written pre‐ and posttests on concepts of natural selection of the 21 prospective teachers; written pre‐ and posttests on views of the nature of science; three e‐mail journal questions; and videotaped class discussions. Findings indicate that prospective teachers initially demonstrated alternative understandings of evolutionary concepts; there were uninformed understandings of the nature of scientific inquiry; there was little correlation between understandings and disciplines; and even the prospective teachers with research experience failed to understand the diverse methods used by scientists. Following the module there was evidence of enhanced understandings through metacognition, and the potential for interactive software to provide promising context for enhancing content understandings. © 2005 Wiley Periodicals, Inc.     

Functional Assessment to Predict Capacity for Work in a Population of School‐leavers with Disabilities

This study reports on an assessment system for school‐leavers with disabilities to identify their capacity for work and the type of transition‐to‐work programme best suited to each person. Participants were 1,556 high school students in four cohorts who left school between 1999 and 2002. Each school‐leaver was assessed by rehabilitation counsellors for functional ability and capacity for work. In a supplementary study, the 2002 cohort was assessed by special transition teachers using a short screening tool. The results demonstrate that there is a predictable hierarchy of functional acquisition among school‐leavers with disabilities and that the single best predictor of future capacity for work and need for transition‐to‐work programmes among this group of young people is the capacity to manage activities of daily living. The results also demonstrate that a short screen used by teachers, together with a behavioural assessment, is sufficient to stream school‐leavers with a disability into a range of transition‐to‐work programmes.     

Conceptions of mathematics and how it is learned: The perspectives of students entering university

This paper reports results from an investigation to identify the conceptions of mathematics held by beginning university students and their approaches to the study of mathematics. Phenomenographic techniques were used to analyze responses to a questionnaire administered to approximately 300 students. An analysis of the results identified a structural relationship between students' conceptions of mathematics and their approaches to learning it, with the majority of students viewing mathematics as a necessary set of rules and procedures to be learned by rote. The results of this research have implications for the ways in which teaching and learning are constituted within universities.
