Abstract EN

This research aimed to investigate the effectiveness of a proposed program in nanotechnology to develop nano-knowledge and decision-making ability among agricultural science student teachers.

For this purpose, a cohort of 33 of 4th agricultural science student teachers in the Faculty of Education, Tanta Universty was randomly selected.

The sequential explanatory mixed method research design was followed.

Nano-knowledge and dicision making posttests were used to collect the quantitative data.

These data were presented descriptively and analysed statistically using one group t-test.

Which yielded statistically significant diffrences between the posttest means scores of the research sample and the hypothetical mean of (65% ).

As for the qualitative data, the semi-structure interview was administered to nine students (used as a stratified sample for the case study).

These data were analysed using thematic analysis, which revealed the reasons for the different levels of growth of nano-knowledge among the sample students in the six levels of Bloom taxonomy, and in the ability to make decisions.

Besides, there was a positive correlation between students^, scores on nano-nowledge and decision making posttests.

The study concluded that the proposed program was effective in developing science student Teachers^, nano-knowledge and dicition making ability.

The research also recommended the necessity of digitizing the teaching and learning processes, developing higher-order thinking skills, and of including nanotechnology within the programs of preparing agricultural sciences student teachers.
