Abstract.ASSESSMENT OF PROSPECTIVE TEACHERS ABOUT AFFECTIVE DOMAIN IN NATURE FIELD TRIPS AS TEACHING AND LEARNING ACTIVITIESScience field trips of students have a positive impact about learning-teaching of Biology and Geology area. Nevertheless, few teachers carry out such activities in the right way. One reason could be the lack of studies concerning to activities focusing in the cognitive and affective teacher domains, especially in the first step of teacher education. Preliminary studies of our research group have shown that future teachers have wrong pedagogical concepts about these activities, sometimes related to their own experience as students. We study the assessment of prospective teachers about affective domain in nature field trips as teaching and learning activities. We analyzed 130 prospective teachers, 81 primary prospective teachers and 49 secondary prospective teachers. We use a single reflection on the merits of the science field trips with respect to the classroom. These prospective teachers were very much in agreement with the importance of these activities in enhancing their pupils’ affective domain. The 49.22% reported that science field trips generated improvements in the affective domain. Although this percentage is higher in secondary prospective teachers than primary prospective teachers (55.10% vs. 49.68%), the differences were not significant. No significant differences were found regarding gender of prospective teachers. Currently when it dominates a negative view of science among students is an important role for these activities. Therefore it is necessary to work these science field trip in-prospective teachers as they play a key role in the teaching and learning of these subjectsKeywords: Science field trip; affective domain; Teaching and learning activities; teacher training.Resumen.Las salidas al medio natural son de gran importancia en la enseñanza-aprendizaje de la Biología y Geología. Sin embargo, todavía son pocos los profesores que integran estas actividades en su docencia y en muchos casos lo hacen de forma poco provechosa. Además, apenas hay estudios centrados en el dominio cognitivo y afectivo de los profesores en este campo, y en particular durante las primeras etapas de su formación. Existe, por tanto, una carencia de información sobre la realización de estas actividades. Estudios preliminares de nuestro grupo de investigación han mostrado que los futuros docentes presentan concepciones pedagógicas erróneas e irreflexivas sobre estas actividades, a veces relacionadas con su propia experiencia como alumnos. Estudiamos la valoración por los profesores en formación del dominio afectivo en las salidas al medio natural como actividades de enseñanza-aprendizaje. Analizamos 130 profesores en formación, 81 profesores en formación de educación primaria y 49 de secundaría. Utilizamos una reflexión individual sobre las ventajas de las salidas al medio real con respecto a las aulas. El 49,22% señalaron que las salidas al medio natural generaban mejoras en el plano afectivo. Aunque este porcentaje es más alto en los profesores de secundaria que los de primaria (55,10% vs. 49,68%), las diferencias no fueron significativas. Tampoco se detectaron diferencias significativas en cuanto al género de los profesores. Actualmente cuando domina una visión negativa de las ciencias entre el alumnado es importante el papel de estas actividades. Por tanto es necesario trabajar estas salidas al medio natural en profesores en formación pues juegan un papel fundamental en la enseñanza-aprendizaje de estas asignaturasPalabras clave: salidas al medio natural, emociones, formación del profesorado, enseñanza aprendizaje del medio natural

A school principal enlisted state park interpreters to organize a series of science field trips to provide a natural environment for instruction, encourage interest in science, and improve exam scores. Students participated in activities one day a month for six months and took exams. Benchmark scores increased compared with the previous year's fifth graders in science. A non-experimental case study examined the emotional and intellectual impressions resulting from students’ experiences of field trip activities. Qualitative data included interviews with school faculty, park interpreters, and 93 students riding to and from the park. Students were asked: what was your favorite activity and why? The study found the elements of novelty, outdoors, touching animals, learning, exploring, (seeing) animals, and personalization to be linked to the factors of play, flow (optimal experience), and free-choice learning. Findings suggest that intrinsic motivation is an important aspect of student enjoyment of field trips.

The introduction of scanning electron microscopy and energy dispersive x-ray analysis to forensic science has provided additional methods by which investigative evidence can be analyzed. The importance of evidence from the scene of a crime or from the personal belongings of a victim and suspect has resulted in the development and evaluation of SEM/x-ray analysis applications to various types of forensic evidence. The intent of this paper is to describe some of these applications and to relate their importance to the investigation of criminal cases.The depth of field and high resolution of the SEM are an asset to the evaluation of evidence with respect to surface phenomena and physical matches (1). Fig. 1 shows a Phillips screw which has been reconstructed after the head and shank were separated during a hit-and-run accident.

Recently, in the materials science field, the ultrahigh resolution analytical electron microscope (UHRAEM) has become a very important instrument to study extremely fine areas of the specimen. The requirements related to the performance of the UHRAEM are becoming gradually severer. Some basic characteristic features required of an objective lens are as follows, and the practical performance of the UHRAEM should be judged by totally evaluating them.1) Ultrahigh resolution to resolve ultrafine structure by atomic-level observation.2) Nanometer probe analysis to analyse the constituent elements in nm-areas of the specimen.3) Better performance of x-ray detection for EDS analysis, that is, higher take-off angle and larger detection solid angle.4) Higher specimen tilting angle to adjust the specimen orientation.To attain these requirements simultaneously, the objective lens polepiece must have smaller spherical and chromatic aberration coefficients and must keep enough open space around the specimen holder in it.
