The study aimed to explore the effectiveness of using rational judgment strategy in teaching science to develop scientific thinking for second-grade students. The researcher utilized the quasi-experimental approach based on (the pre/post designing) of two groups: experimental and control. As for tools: a test of scientific thinking prepared by the researcher that proved its verification of their validity and reliability. The test applied on a random sample of (66) students, divided into two groups: (34) experimental, and (32) control. The results showed that the experimental group outperformed the control group in the post-application of the scientific thinking test, In each skill separately, and in the total skills. The study recommended including a book in decision science teacher of middle school rational judgment and the steps of teaching it, training teachers to use the rational judgment strategy to develop the scientific thinking of their students.
New Schiff base ligand 2-((4-amino-5-(3, 4, 5-trimethoxybenzyl) pyrimidin- 2-ylimino) (phenyl)methyl)benzoic acid] = [HL] was synthesized using microwave irradiation trimethoprim and 2-benzoyl benzoic acid. Mixed ligand complexes of Mn((ІІ), Co(ІІ), Ni(ІІ), Cu(ІІ), Zn(ІІ) and Cd(ІІ) are reacted in ethanol with Schiff base ligand [HL] and 8-hydroxyquinoline [HQ] then reacted with metal salts in ethanol as a solvent in (1:1:1) ratio. The ligand [HL] is characterized by FTIR, UV-Vis, melting point, elemental microanalysis (C.H.N), 1H-NMR, 13C-NMR, and mass spectra. The mixed ligand complexes are characterized by infrared spectra, electronic spectra, (C.H.N), melting point, atomic absorption, molar conductance and magnetic moment me
... Show MoreThe research includes the synthesis and identification of the mixed ligands complexes of M(II) Ions in general composition [M(Lyn)2(phen)] Where L- lysine (C6H14N2O2) commonly abbreviated (LynH) as a primary ligand and 1,10-phenanthroline(C12H8N2) commonly abbreviated as "phen," as a secondary ligand . The ligands and the metal chlorides were brought in to reaction at room temperature in ethanol as solvent. The reaction required the following molar ratio [(1:1:2) (metal): phen:2 Lyn -] with M(II) ions, were M = Mn(II),Cu(II), Ni(II), Co(II), Fe(II) and Cd(II). Our research also includes studying the bio–activity of the some complexes prepared against pathogenic bacteria Escherichia coli(-),Staphylococcus(-) , Pseudomonas (-), Bacillus (-)

After analyzing the results, it has been Shown that the Following are the most important problems :-
1. limitedness of the period of application.
2. Insufficiency of the hours specified for the Computer.
3. Insuff
From the above we conclude that the Peronist represents one of the distinguished scientists who had a prominent role in supplying the Arab and Islamic Heritage Library scientific achievements that have had their impact on the Arab-Islamic civilization at a high level of knowledge has given us
Characterized the study of Islamic movements in Lebanon, as other studies in the Arab world by being the study of the subject in a different and distinct field on more than one level, environment in which they were composed of components very sectarian and confessional diversity

In recent decades, the world has faced some rapid technical developments, affected on many fields of life, which had the best chance in the information and communication technology, such that it created an entirely new situation, summed up the life and development of business enterprises. This is while these developments have changed a lot the reputation of management institutions and civil society organizations in return. In addition, they have linked the citizen and those institutions in their different specialties within a distinct electronic format called e-management in the contemporary literature.
This study attempted to highlight the importance of investment in building e-management by linking citiz
