In the Pakistani context, teachers and students often find it difficult to teach and learn geometry, particularly proofs using deductive reasoning skills. Dynamic Geometry Software (DGS) is a widely recognised tool that mediates students’ reasoning skills. However, its efficacy in developing the reasoning skills has not yet been explored in the Pakistani school contexts. Before spending the time and resources in integrating the software in geometry instruction, it is necessary to investigate the effectiveness of DGS in the Pakistani context. This study, therefore, aimed at determining the effect of DGS (Geogebra) on reasoning skills of students of Grade 7 in one of the private schools in Karachi, Pakistan. The study used quasi-experimental pre-test and post-test design. Sample of 40 and 36 students comprised Experiment Group (EG) and Control Group (CG), respectively. In the pre-test CG performed significantly better than EG (U=468, z=-2.659, pr=0.31). However, in the post-test, score of EG (Mdn=6.50) was higher, as compared to score of CG (Mdn=6.00), although the difference was not significant which is represented by small sized effect (U =615.50, z=-1.098, p>0.05, r=0.125). Specifically, DGS-based instructions resulted in significant improvement at visualisation level as compared to the instructions without DGS. However, both instructions (with and without DGS) were equally helpful at the analysis and deduction level. Nevertheless, no improvement was reported at the informal deduction level. The findings of this study encourage the practitioners to use DGS for the development of students’ geometrical reasoning, especially while designing the instructions at visualisation level.
منکھ تے سماج دا آپسی تعلق ڈھیڑ گوہڑا تے پرانا اے ۔منکھ سماج وچ اپنی ہو ند تے پہچان نوں سب توں وکھرا برقرار رکھن لئی کئی کم کر دا ہے ۔کدے ایہہ کم سماج لئی لائحے وند ہوندے نیں تے دوجے منکھ ایہناں توں لابھ چکدے نیں ۔منکھ کئی واری حیاتی گزار دے ہوئے اجیہے کم وی کر جا ندا اے جو اوس دی اپنی ذات تے سماج لئی لائحے وند نہیں ہوندے ۔ ایس دے سٹے اوس دی اپنی ذات تے سماج اتے بھیڑے پیندے نیں ،سٹے وجھوں سماج اندر کئی اوکڑاں تے برائیاں دا جنم ہو ندا اے ۔فیر ہو لی ہو لی سارا سماج اوکڑاں دا شکار ہو برائیاں دے کلاوے وچ آ جاندا اے ایہناں اوکڑاں تے برائیاں دا سدھے یا ان سدھے طور اتے منکھی وطیرے تے وی اثر پیندا اے ۔ شاعر کیوں جے سماج دا حساس ترین منکھ ہوندااے ایس لئی اوہ ایہناں دا اثرات نوں اپنی شاعری راہیں بیان کرن دا جتن کر دا اے ۔
سلطان کھاروی وی ایہناں کویاں وچوں اک کوی ہے جو سماجک گھٹناواں نوں اکھوں اوہلے نہیں کر دا۔ سگوں ان جھک ہو کے شعراں راہیں بیان کر کے نہ صرف لو کائی نوں ایہناںبارے جانکاری دیندا اے سگوں ایہناں خلاف لوکائی وچ نفرت پیدا کر ن دا جتن وی کر دا اے۔ آپ نے سماجک ،دھارمک ، راج نیتک توں وکھ جنہاں اوکڑاں تے برائیاں دا ذکر اپنی کوتا وچ کیتا اے ۔ اوس دا جائز ہ انج اے ۔
کسے وی دیس دی ترقی لئی اوتھے دی رج نیتک حالت دا چنگا ہونا بہوں چنگا جانیا جاندا اے۔ امن و امن دی صورت چنگی ہوون کارن سماج اندر ہر قسم دی ترقی ہووے گی ۔عدل و انصاف...
It is well fact that before the advent ofthe Prophet Mu hammad (PBUH) the whole world was in totally darkness. Oppression was the order of the day. Womenfolkwas the most depressed segment ofthe society but when Islam cameit notonlyenjoined it followers to strive for theestablishmentofa just society in all walks of life. The issues of oppression of women folk was particularly addressed. Many verses ofthe Holy Quran and Sunnah clearly elaborated the duties as well rights of women. Islam considers woman as equal to man in respect ofduties and rights keeping her physical difference in view. In this article six points have been chosen for discussion which are as under equality of woman with man in humanity, equality in rights and obligation, equality in ownership and employment, equality in responsibility and equality in punishments Equality in liaan process.
Carbonic anhydrase is metal-containing enzyme that contains Zn and involves the carboxylation of water into carbonic acid, which normally converts into bicarbonate and protons
Carbonic anhydrase inhibitors (CAIs) are utilized to lower the intraocular pressure (IOP) in glaucoma condition and also decrease the inflammation associated with increasing ocular hemodynamics, and ocular apoptosis.
During the course of research period, a number of synthesized compounds were analyzed by bovine carbonic anhydrase-II (bCA-II) for development of new inhibitors. For this purpose high throughput biochemical mechanism based assay was employed for the identification of new inhibitors of CA-II enzyme. Spectra max-340 and M2 spectrophotometer from Molecular Devices (USA) were used to measure the inhibition potential through absorbance.
Out of numerous classes of compound only schiff bases of triazole, tosylhydrazone (sulfonohydrazone), benzylidene and thiourea derivatives, were found to be good inhibitors of CA-II. The identified inhibitors were subjected to IC50 determination by serial dilution. The Ez-fit enzyme kinetics soft were employed to calculate the IC50 values from the % inhibition. The benzylidene derivatives exhibited. IC50 values in the range of 52.68 ? 0.47 to 348.57 ? 3.32 ?M. Schiff Bases of triazole derivatives have shown IC50 values between 98.23 ? 1.60 to 285.87 ? 2.67 ?M. While thiourea derivative exhibit excellent inhibition potential which illustrated IC50 values in the range of 1.90 ? 1.30 to 25.90 ? 2.05 ?M when compared with the standard inhibitor acetazolamide IC50 = 0.13 ? 0.05. Among all the compounds thiourea derivatives can serve as lead compounds for the identification of new inhibitors of CA-II.
