The Effect of Collective Games in Developing the Social Behavior for the Kindergartens Children

College Of Basic Education Researches Journal, Volume 15, Issue 1, Pages 1-24

Abstract: The current research have aimed to identify "the effect of collective games in developing the social behavior of the kindergarten children". The researchers have used the experimental design with two equivalent groups, experimental and control, by pre and posttests. The research sample consisted of (50) children as 25 ones for each group, applying the collective games on the experimental group, then the researcher has conducted equivalence process between the two groups about several variables as age calculated with months, gender, and academic achievement of father and mother. Then the researcher has prepared the scale of social behavior which has been verified of its validity by introducing it to several experts, the reliability coefficient was identified by re test method amounted (0,82), as well as the researcher has prepared a program for collective games which has been verified of its validity by introducing it to several experts to decide the validity of each game for its specialized purpose and aim , then their opinions were re formulating some of these games in terms of linguistic items. The experiment continued 12 weeks by applying the tool on the two research groups to identify the effect of collective games in developing the social behavior for the kindergarten children, after data has been treated statistically by using t test for two independent samples and t test for two correlated samples, so the results have shown the following: " There is no statistical difference at significance level (0,05) in the mean of experimental group degrees in the pre and posttest to the scale of social behavior which has been prepared by the researchers. In the light of these results, the researchers have recommended researchers have the importance of preparing sessions for the teachers of kindergartens to enable them in giving assistance to select and put the programs of collective games, as well as the researcher has suggested conducting a study about the effect of collective games in reducing the aggressive behavior for the children of kindergarten .

This research was conducted to study the effect of alfalfa Medicago sativa residues (shoot) on germination and growth of two legumes species Vigna unguiculata and Cicer arientinum . Laboratory results showed that the aqueous extract of the residues at the concentrations5,10,15,20,25% w:v caused significant reduction in seed germination and seedling growth of the two legumes as compared with distilled water ,the less germination was recrded 32% at the concentration 25%in Cicer arientinum seeds also the less plumule and radical length recorded as 0.23,0.10cm in Cicer arientinum at same concentration.
The results of green house experiment showed inhibition in seed germination and growth of the two legumes growing in the soil containing alfalfa residues added at the ratio 10%w:w and incubated for (0,1,2) weeks as compared with control (without residues) ,the less germination recorded as 65% in Cicer growing in the soil containing resdues zero incubation.

The current research aimed to discover the Effectiveness of Chemistry Teaching according to learning dimensions model in the development of chemical concepts and the meta-cognitive skills for first grade secondary students.
The Population of research consists of students of first grade secondary in Libya, also the research was applied on a sample that selected intentionally from students of first grade secondary in Libya, the sample has been divided into two groups, the first was an experimental and consisted of (33) students, where the second was the control and consisted of (31) students.
Tools of this research are the following:
1. Teacher Manual.
2. Student Handbook.
3. The achievement test of chemical concepts.
4. Measurement of meta-cognitive skills.
By using T-test for independent groups to compare between the control and experimental group, we got the following results:
1. The Effect of Chemistry Teaching according to learning dimensions model on the development of chemical concepts and the meta-cognitive skills for first grade secondary students.
2. There are statistically significant differences at (α ≤ 0.001) between the mean-degrees of the students of both the experimental, and the control groups in the achievement test of the chemical concepts.
3. There are statistically significant differences at (α ≤ 0.001) between the means-degrees of the students of both the experimental group, and the degrees of the students of the control group on the full skills measurement of the meta-cognitive skills and its sub-dimensions (self-regulation skills, academic tasks skills, ,procedural control skills).
In the light of the research results, the researchers provided a number of recommendations including:
1. The necessity of a development of style of chemistry teaching in secondary school.
2. The recognition of the content of high school chemistry textbook in the light of the learning dimensions model.
3. Conduct training programs for teachers of chemistry based on the use of the learning dimensions in the teaching of chemistry.
The researchers also provided a number of suggestions to conduct future studies one of them is “The Effect of learning dimensions model on the development of concepts and the meta-cognitive skills in the teaching of other subjects".

Alternative Effect Between Cucurbita pepo and Cucumis sativus On germination and some growth characteristic

College Of Basic Education Researches Journal, Volume 12, Issue 4, Pages 881-898

The present study was designed to determine the alternative effect between Cucurbita and Cucumis, the research involved two experiments in laboratory also in green house and the results showed that:-
1-The effect of aqueous extract of Cucurbita and Cucumis at concentrations (0,3,5)%w:v in germination and seedling growth of Cucurbita. The results showed a variation that there is response in germination and growth when compared with the control, the highest percent of increasing was (33.3,23,7.3) % in the Cucurbita extract at (3%).On the other hand, the highest percent of reduction was ( 13.3,9,6) by effect of Cucumis extracts .
2-The effect of aqueous extract of Cucurbita and Cucumis at concentrations (0,3,5)%w:v in germination and seedling growth of Cucumis they caused reduction, the highest percent of reduction was (51.8,61.1,53.5)%, respectively at (3%) of Cucurbita extracts.
3-The effect of addition of Cucurbita & Cucumis residues in germination and growth of Cucurbita, the results revealed a different response, the highest percent which was ( 10,21.7,13.9,129.4,91)% were shown by Cucurbita residues that incubated for one week, while the highest percent of reduction was (20,40.2,28.4,24.5)% at the soil contain Cucumis residues without incubation.
4-The effect of aqueous extract of Cucurbita and Cucumis at concentrations (0,3,5) % w:v in germination and seedling growth of Cucumis the highest increasing(10.6%) in germination and (11.6,4,8.8,1.3) % in growth for Cucumis residues that incubated, where is the highest reduction was (28.2,22.6,7.3, 27.2, 21.5) % respectively in the soil contain Cucurbita residues incubated.
Also the results showed that Cucurbita and Cucumis residues (not incubated) and Cucumis residues incubated caused increasing content of carbohydrate in Cucurbita and Cucumis ,the highest value (31.82%) in Cucurbita affected by (Cucurbita residues not incubated),but the Cucurbita residues incubated caused reduction in content of carbohydrate in Cucurbita and Cucumis, the highest reduction (30.45%) in Cucurbita.
