In the present study high-school pupils’, and adult students’ opinions were evaluated through a modern structured MOODLE interactive course, designed for the needs of the laboratory course “Automotive Systems”. The study concerns Greek secondary vocational education pupils aged 18 and vocational training adult students aged 20 to 50 years. The multistage, equal size simple random cluster sample was used as a sampling method. Pupils and adult students of each cluster completed structured 10-question questionnaires both before and after attending the course. A total of 120 questionnaires were collected. In general, our findings disclosed that the majority of pupils and adult students had significantly improved their knowledge and skills from using MOODLE. They reported strengthening conventional teaching, using the new MOODLE technology. The satisfaction indices improved quite, with the differences in their mean values being statistically significant.展开更多

Its versatility allows being adapted to the Clinical and Educational Psychology. The objective to give access to all people a friendly-user tool with a touch screen that stimulates and catches the attention, enabling to teach knowledge, skills and values. It is divided in 2 complementary and interdependent parts. On one hand, the mixed contents are found in the Digital Boards (interactive and dynamic) structured in sessions that are combined into an entire psycho-educational program. This program facilitates the comprehension, acquisition and practice of the learning object. On the other hand, the process and the instructions of the material are described by a script which contributes to a better attitude that attracts the participants and stimulates to keep on learning. The efficiency and value of the methodology is evaluated at the beginning and at the end of the learning process, showing quantitative features in graphs and a weekly field study gathering the qualitative data. The Average improves significantly in every group, apart from the program that was used (Emotional Skills, Self-esteem, attention, Sexuality, Self-control, Problem-solving) and also in every individual according to the specific target of every subject. The application of this tool enables to diversify the knowledge to every area of the Psychology. In this sense, experts and participants enjoy the Education interactively in a recreational way reinforcing the Emotional and Social Intelligence.展开更多
