چاند مدھم ہے روشنی کم ہے

چاند مدھم ہے، روشنی کم ہے
خواب دھندلے ہیں، آنکھ بھی نم ہے

عمر حاضر جواں دلوں کا کھیل
عمرِ رفتہ عجیب سا غم ہے

زندگانی نثار تم پہ کروں
وار دوں تم پہ سب مگر کم ہے

زندگی! تیرے آستانے پر
موت آنے سے ایک ماتم ہے

دل بھی چاہے کہ زخم تازہ رہیں
وقت کی راگنی بھی مدھم ہے

جس قدر خواہشیں ہیں سینے میں
خضر کی عمر بھی ہمیں کم ہے

آئو ہم بھی گزار لیں لمحے
سانس رکتی ہے آخری دم ہے

تم فضاؔ ہو جہاں پہ چھا جائو
ہم دھواں ہیں ہمیں یہی غم ہے

سید محمد محسن اور ان کا منظوم ترجمۂ قرآن: ایک تنقیدی مطالعہ

Sayyid Muḥammad Moḥsin was Lucknow based poet. The biographers, though, seem unaware of his life and poetic profile. He did interpretative translation of the Holy Qurʼān in Urdu in Mathnavī form with the title of ‘Manẓūm Urdu Tarjama’. This translation was published from Lucknow in 1986. The translation in poetic form asks for technicalities which this work lacked perhaps. This article surfaces errors which were identified in areas of poetic exposition, concept formation and stylistic coherence in the translation work.

Exploring Grade Ten Students’ Conceptual Understanding and Alternative Conceptions About Photosynthesis: Comparisons Across School System and Gender

Photosynthesis is an important yet a complex concept of school biology. Literature has identified numerous alternative conceptions of students about this aspect of Biology. Keeping in mind the importance of this aspect of life sciences this study aimed to examine grade 10 students’ conceptual understanding and alternative conceptions about photosynthesis with a view to compare it across school system and gender in the city of Gilgit. The study employed cross sectional survey design. A 20-item Conceptual Understanding about Photosynthesis (CUP) test was adopted for the study. The test encompassed six major aspects of photosynthesis (i.e. physiology, energy, biochemical, autotrophy, photosynthesis and respiration, ecology). CUP test was directly administered to randomly selected 204 grade 10 students from public (n =101) and private (n =103) schools of Gilgit. The selected sample represented male (n =102) and female (n = 102) students. Results of the study revealed that students’ overall conceptual understanding about photosynthesis was 53% of the total score (20). However, students’ performance in three aspects of photosynthesis (i.e. ecology, autotrophy, biochemical reaction) was higher than the overall score. Conversely, the students found rest of the three aspects (i.e. energy, photosynthesis and respiration, and physiology) relatively difficult. Furthermore, students from private schools outperformed their counterparts in public schools in overall conceptual understanding about photosynthesis (p<0.001) as well as in the aspects of biochemical (p<0.001), photosynthesis and respiration (p<0.001), and ecology (p<0.001). Moreover, score favored male students in the two aspects including energy (p<0.05) as well as photosynthesis and respiration (p<0.01). Results of the study would have implications for practice, policy and further research.
