Effect of Synthetic and Natural Specimen Use on Process Skills and Applications in Secondary School Biology Practical in Ekiti State, Nigeria.

Effective teaching of Biology practical entails the use of specimens. However, in Nigeria, some natural specimens are difficult to obtain when needed, hindering the learning and application of science process skills. Consequently, teachers resort to pictorial representation of specimen and to online prints for Biology practical instructions. Another possible alternative less discussed is the use of synthetic or artificial specimens. The goal of this study, therefore, was to examine the effect of using synthetic and natural specimen on practical skills- process skills acquisition and application in Biology practical in secondary schools. It sought to determine the efficacy of using synthetic specimens to complement or substitute for natural specimens in teaching Biology practical. The study employed the pre-test, post-test, control group, quasi- experimental design. A total of 212 senior secondary school (SS II) Biology students in six selected government-owned high schools in Moba and Ijero Local Government Area of Ekiti state, Nigeria, were randomly selected for the study. The schools were paired and assigned to two experimental groups (using synthetic and natural specimens) and a control group (using conventional drawings). Eight instruments were employed for the study and used at treatment stage. Data collected were analyzed using Analysis of Variance (ANOVA), Analysis of Covariance (ANCOVA) and Multiple Classification Analysis (MCA). The results showed that there was a significant effect of synthetic specimens and natural specimens on the proficiency of the students in basic science process skills acquisition (F = 60.470, P<0.05). However, the mean gain of 3.884 which existed between the two groups showed that natural specimens were slightly more effective than synthetic specimens. The results also showed a significant effect for the use of synthetic specimens on process skills acquisition and applications of Biology concept among the students (F = 74.773, P<0.05). The study concluded that synthetic specimens are equally effective as natural specimens in improving the acquisition and application of basic science process skills of students in Biology.

Measuring design innovation for project-based design assessment: considerations of robustness and efficiency

Los enfoques instructivos para la adquisición de habilidades en procesos de diseño innovativo para ingenieros y diseñadores son fundamentales para desarrollar competencias de diseño. Se necesitan recursos que permitan una evaluación eficiente y válida de los resultados del diseño, sin embargo, los métodos de evaluación actuales no son adecuados para los proyectos heterogéneos de las clases de diseño basadas en proyectos auténticos como diseño final. Por ello, nosotros desarrollamos una medida robusta y eficiente, y la validamos con un conjunto grande y diverso de resultados de diseño de una clase de diseño basada en proyectos. La medida se basa en juicios expertos sobre el valor y la funcionalidad de los conceptos de diseño derivados de una serie de requisitos de diseño ponderados por su importancia.Las nuevas medidas de evaluación de los resultados en el contexto de entornos de diseño auténticos basados en proyectos, como el desarrollado en el presente estudio, deben interactuar con las métricas basadas en procesos para crear una entrada de mayor calidad en la evaluación general de rendimiento del equipo de diseño.

An Audit of Goal Planning in Rehabilitation

Objective: The study had the following objectives: (1) To audit current practice within a system of client-centered goal planning, and (2) Identify areas of staff training need and ways in which these training needs could be addressed. Design: Data were collected using qualitative methods comprising documentation analysis, observations of meetings, training needs focus groups, and interviews. Setting: The project was carried out at a center that specializes in neurological rehabilitation and uses a system of client-centered goal planning. Results: The documentation analysis showed that goal planning succeeded in achieving its targets at levels ranging from 32% to 96%. Observations showed a reluctance to chair goal-planning meetings and that key staff were absent and/or important information was unavailable in some cases. Training needs assessments showed that some aspects of the philosophy and process were poorly understood. Conclusion: A structured interdisciplinary training package that focuses on knowledge about goal planning and the acquisition of necessary process skills is needed. The structure and content of such a package are briefly outlined.

Process skills acquisition, cognitive growth, and attitude change of ninth grade students in a scientific literacy course

AbstractThis is a report of the effects of a scientific literacy course on the skills, cognitive ability, and attitude of students in the first year of high school. Specifically, the research examines (1) whether it is possible to teach scientific skills, (2) whether a literacy curriculum affects attitude and cognitive ability, and (3) whether incoming student characteristics affect the development of attitude and cognitive abilities. Two hundred and fifty (126 male and 124 female) ninth grade students were enrolled in a specially designed literacy course which met for 3 hours and 20 minutes each week for 39 weeks. Students were pretested for logical, spatial, verbal, and mathematical ability, as well as for attitude toward self and science, and psychological type. The course was successful in teaching skills. In addition, there were significant increases in spatial, verbal, and quantitative ability. Increases in cognitive ability were predicted by logical ability, measurement skills, and academic self‐concept. Attitudes declined as a result of participation in the course. Self concept and mastery were related to cognitive variables and motivation, mastery, and control were related to psychological type.
