The development of the ability to sing or play in tune is one of the most critical tasks in music training. In music education, melodic patterns are usually learned by imitative processes (modelling). Once modelled, pitch sounds are then associated to a representation according to a syllabic system such as the Guidonian system-or an arbitrary single syllable-or western graphic notation system symbols. From a didactic standpoint, few advances have been made in this area besides the use of audio-supported guides and existing software, which use a microphone to analyse the input and estimate the pitch or fundamental frequency of the given tone. However, these programmes lack the necessary analytical algorithm to provide the student with precise feedback on their execution; and also they do not provide adequate noise-robust solutions to minimize the student assessment
Este trabajo expone el diseño, desarrollo y evaluación de un software como apoyo docente en una materia de formación musical básica para futuros maestros generalistas. La evaluación del programa fue realizada por estudiantes de primer año del Grado de Maestro en Educación Primaria. Cumplimentaron un cuestionario que recogió sus opiniones (versatilidad, eficacia, facilidad de uso, calidad del entorno gráfico, adecuación, interés, facilitación del aprendizaje, feedback, funcionalidad) y percepciones sobre aspectos más generales (control, orientación, afectividad, consulta, verificación, seguimiento). Los resultados sugieren que el alumnado percibe EMOLab como herramienta de gran ayuda en el desarrollo de sus habilidades musicales.Palabras clave: Tecnología musical, enseñanza asistida por ordenador, formación de maestros no especialistas.This article shows the design, development and evaluation of a software for teaching support in a music training course for pre-service non music teachers. The aim of EMOLab has been addressing to both production and perception musical activities. The assessment of software was done by freshmen enrolled in Elementary Education Teacher Training degree. They completed a questionnaire that collected their opinions (versatility, efficiency, ease of use, quality of graphical environment, adequacy, interest, facilitating learning, feedback, functionality) and perceptions on more general aspects (control, guidance, affection, consultation, verification, tracing). The data suggest that students perceive EMOLab as a helpful tool in developing their musical skills.Keywords: Music technology, computer assisted instruction, non-music teacher training. INTRODUCCIÓNEn los planes de estudio de las dos últimas reformas, los alumnos universitarios de nuevo ingreso elegían su itinerario de especialidad y cursaban materias específicas desde el primer curso de los estudios. Sin embargo y desde la sustitución de los títulos de diplomatura por los títulos de grado, los dos primeros cursos de la carrera de Maestro son comunes a todos los estudiantes, sea cual sea el itinerario formativo elegido. Estos dos primeros cursos de grado incluyen materias generales de formación disciplinar básica. En tercero y cuarto cursos, se incluyen las materias específicas de didáctica de las especialidades, por ejemplo, las propias de las menciones de Lengua Extranjera, Educación Física y Educación Musical. La materia Didáctica de la Expresión Musical es una materia troncal de primer curso del grado de Maestro de Ed. Primaria, destinada a la formación básica musical y didáctica de todos los futuros maestros. Un pequeño porcentaje de los alumnos que cursan esta materia deciden estudiar la especialización de Educación Musical en tercer y cuarto cursos (Mención en Educación Musical), bien porque tienen suficientes experiencias musicales previas, bien porque tienen una titulación musical. En el primer caso, deben realizar una prueba de nivel y en el segundo caso cursan directamente la mención. El resto de alumnos harán otra...
Abdominal and vaginal sonographic monitoring were compared in 45 patients undergoing follicular development for the purposes of artificial insemination (N = 22) and in vitro fertilization (IVF; N = 23). Transvaginal sonography recorded a significantly (p less than 0.05) higher number of follicles from cycle day 10 on, compared to the abdominal (sector and linear) approach. Starting on day 8, the size of the dominant follicle was also significantly (p less than 0.05) higher when transvaginal endosonography was used. The number of follicles greater than 15 mm on the day of human chorionic gonadotropin (hCG) administration was correlated with the number of oocytes retrieved in patients undergoing IVF. There was a significant linear correlation when transvaginal (r = 0.86, p less than 0.001) and sector (r = 0.57, p less than 0.05) scans were used.
The internal and external interorbital diameters are measured during pregnancy. A case of holoprosencephaly was diagnosed via ultrasound on the basis of the reduction of both diameters.
