Abstract |
This study aimed at investigating the instructional methods used by lower elementary stage teachers (1 – 3) in teaching reading to third grade students at UNRWA schools in Jordan. The study sample consisted of (8) male and female teachers purposefully selected. To answer the research questions both quantitative and qualitative methods were used. The study instruments included an Observation Checklist of teaching reading lessons, and interviews with lower elementary stage teachers, two Arabic language curriculum designers, and third grade students. For the purpose of conducting the study, both the “General Guidelines and Objectives of the Third Grade Arabic Language Curriculum”, “Our Arabic Language Textbook” and the “Teacher’s Book” were carefully studied and analyzed. Results of the study showed that (58%) of lower elementary stage teachers tend to employ mono teacher-oriented instructional methods, while (33%) tend to employ multi instructional strategies. The study also highlighted the importance of the “General Guidelines and Objectives of the Third Grade Arabic Language Curriculum” in helping teachers employ various effective instructional techniques capable of achieving the desired outcomes when teaching reading lessons to third grade students. Keywords: instructional strategies, lower elementary stage teachers (1 – 3), reading लेस्सोंस http://www.najah.edu/index.php?page=2150&l=en&extra=%26id%3D599. |

Abstract |
The kinetics of the complexation reaction of palladium with 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP) has been studied in the stability time at the optimum pH of 3.53 in presence of 50% ethanol. The effect of ionic strength and temperature on the reaction rate were reported. A mechanism has been postulated and the stability constants of the individual steps were determined. The Arrhenius and thermodynamic parameters were evaluated and discussed. |

Abstract |
Calibration graphs have been obtained for mercury, zinc and copper ions using buffered (pH 7।4) stream water and centrifuged stream water samples. Two hypothesis explaining the shape of the obtained calibration graphs have been suggested; one refers the shape to the adsorption of-trace elements on the suspended particles and on the container surfaces, the other hypotheses refers the shape of calibration graphs to the presence of chemical interference. The strength of the two hypotheses has been compared. The effect of time on the shape of the calibration graphs has also been investigated. http://www.najah.edu/index.php?page=2149&l=en&extra=%26id%3D490 |

Abstract |
The effect of solvents on ? values of the Hammett equation which characterizes the hydrolysis of Benzylidene Benzoylhydrazone (BBH) and its derivatives (m—NO2 m—CH3, m—OCH3 and m—Cl), have been studied with four solvents (MeOH, Et0H (1), n—BuOH, and DMSO) by U।V. — spectrophotometry. The effects of solvents on ? values, one of the Hammett equation parameters, have been reported and discussed. http://www.najah.edu/index.php?page=2149&l=en&extra=%26id%3D501 |

Abstract |
Azaallenium salt 7 was isolated at low temperature by the addition of bis (methylthio) acetylene to nitrilium salts। The isolated azaallenium salt 7 was rearranged to afford the 1:1 heterocyclic adduct 8. A detailed mechanism is discussed. http://www.najah.edu/index.php?page=2149&l=en&extra=%26id%3D500 |

Abstract |
In a submerged rigid oil storage tank it is possible to evaluate the internal and external hydrodynamic forces separately। Internally the forces are due to internal waves generated at the oil-water interface. Externally, they are due to radiated waves. When such a tank is made of steel, at it is usually the case, the internal and external forces get coupled through the flexibility of the shell, hence their solutions become inseparable. The following is an analytical treatment for the case of a flexible tank it expands the solution of the rigid tank to include the shell flexibility effect. The submerged tank is assumed to be subject to a harmonic lateral ground excitation. http://www.najah.edu/index.php?page=2149&l=en&extra=%26id%3D519 |

Abstract |
Isomerization and hydrosilylation reactions of terminal olefins have been reported under thermal and photochemical conditions using Ru3 (C0) 12, 1, and HRu3 (CO)!!, 2,11 '0 In a very recent work, we reported E LI that 1 catalyses both Isomerization and hydrosilylation reactions of 1-octene (eq। 1). It has been found that the isomerization reaction occurs via lower nuclearity catalytic species that result from fragmentation of the mother cluster 1. Evidence in favour of concurrent cluster catalysis was also reported. On the other hand, the hydrosilylation reaction occurred via cluster catalysis at first and after some-time fragment catalysis occurred. http://www.najah.edu/index.php?page=2149&l=en&extra=%26id%3D520 |
