أثر وحدة مقترحة بمقرر الأحياء لطلاب المرحلة الثانوية لتنمية الوعي بالمخاطر البيئية الناتجة عن استخدام تكنولوجيا النانو

الملخص EN

The study aims to identify the effect of a proposed unit in the biology course for high school students to develop awareness of environmental risks resulting from the use of nanotechnology.

The researcher used the experimental approach with an experimental design for one group.

The secondary school at Tamiya Educational Administration, and the researcher prepared a proposed unit in nanotechnology dealing with the definition of nanoscience and its most important environmental applications, environmental risks resulting from the use of nanomaterials, and a guide for the teacher, and to verify the effectiveness of the unit content on developing awareness of the environmental risks resulting from the use of nanotechnology.

The researcher measures the awareness of the environmental risks of nanotechnology, and the research tool was applied to an exploratory sample consisting of 90 male and female students of the first grade of secondary school at Al-Azizia Secondary School of the Tamiya Educational Administration, in order to assess the validity and reliability of the two scales by calculating the validity of the internal consistency and the stability coefficient of Alpha Crownbach for the two scales.

The results revealed the impact of the proposed unit on awareness development Concerning the environmental risks of nanotechnology, the results also showed that there are statistically significant differences at a level of significance (0.01) between the mean scores of students in the pre and post application of the scale of awareness of nanotechnology environmental risks.
