A sample of 22 registered nurses participated in an educational program to learn comprehensive physical assessment skills. This study investigated the effects of that program on their nursing practice. Administration of tests and questionnaires provided a measure of the: (a) use of physical assessment skills; (b) knowledge of physical assessment; (c) changes in nursing practice since learning the skills; (d) barriers to the use of the skills. The model used for the program's curriculum development was adult learning theory. The curriculum focused on this theory's key aspects. Namely, adult students build new skills on their past knowledge and already developed skills. Additionally, they must see the relevance of learning the skills and be able to apply them in their current life situation. The findings suggest this model was appropriate. The nurses in the study used the majority of learned skills after they completed the program. Their knowledge concerning these skills also showed dramatic improvement. The major findings regarding the increase in knowledge and use of physical assessment skills, positive changes in nursing practice and lack of barriers to the use of skills indicate that an educational program in physical assessment can be very beneficial to nurses. The results support those of previous studies in that nurses will use the physical assessment skills they have learned in continuing education programs. The implications for nursing practice and education were discussed. Suggestions were then made for future research in this area.

Initial teacher education is an area of weakness within the Chilean education system. Yet it is highlighted as a crucial aspect of educational success. Success in educational improvement depends mainly on the teachers (because they enact a reform by putting it into practice), and teacher thinking is likely to influence teacher decision-making. How teacher conceptions and practice change, and how to facilitate this change, was the focus of this study. It explored to what extent peer assessment could facilitate change in pre-service science teachers’ conceptions and practices regarding conceptual explanations in science teaching.In a quasi-experimental design, a ten-session peer assessment intervention was carried out with thirty seven pre-service science teachers in three Chilean universities, each with an experimental and control group. The intervention sought to develop changes in teachers’ conceptions about the quality of explanations and in their skill of explaining scientific concepts. Teachers' thoughts were obtained through a peer assessment questionnaire, feedback sessions, focus groups and interviews. The quality of their explanations was measured at pre, post and follow-up in their eventual first job via video-recorded microteaching episodes using observational analysis. Inter-rater reliability was calculated on 5% of all qualitative data and all the videos were rated by two researchers in a blind process. Qualitative analysis indicated how teachers transformed their conceptions about the quality of explanations from general pedagogical knowledge into pedagogical content knowledge. A quantitative instrument was created to evaluate student teachers’ explanations in practice. Its reliability enables the assessment the skill of explaining based on ten elements (Cronbach’s alpha=.77). Results showed pre-service teachers significantly improved their explanations of scientific concepts in some practical aspects, although not all of them were transferred into real teaching contexts. The changes in student teachers’ conceptions and practice were analysed to indicate how the process occurred, to what extent peer assessment had a role on it, and which elements facilitated or made difficult the transference of the skill of explaining into real teaching. These results indicated that peer assessment can play a noteworthy role in teacher education to develop skills. There are implications for policy and practice in this study, not only for teacher education but also for in-service teacher professional development, not only for Chile but also for other countries.
