Abstract EN

The objectives of this study were to identify the practical laboratory skills required for biology teachers in secondary schools, and the most important practical lab skills needed to be trained from the biology teacher's points of view.

It also aimed to measure the impact of a developed training program in those skills.

Then the researcher prepared a questionnaire and a check list, of six basic practical lab skills.

(1-Dry taxidermy of the fish.

2-Preparation of formalin (5%).

3-Wet taxidermy of the fish.

4-Investigation of the pool and lade water to determination of the protozoa.

5-Blood hemoglobin examination.

6.Manual microtome uses for preparing plant parts sections (In a young Geranium shoot)).

Based on that, the training program was developed to help Biology Teachers to improve their scientific skills.

Training was performed in ten days.

The most important findings of this study were summarized as follows: - Determination of a list of the practical Lab skills required for secondary school Biology teachers consists of (44) basic practical Lab skills organized in 6 categories.

- The impact of the program in developing the laboratory practical skills of Biology Teachers showed significant differences at the level (0.05) to the mean of checklists between the pre- test and post - test scores in favor the post best.

The ratio of the modified acquiring for Black is high (1.71) and this confirms the effectiveness of the training program.
