The importance of constructivist approach to teaching and learning science is growing significantly. Much of the efforts have been put to develop pedagogies that take into account constructivist views to improve students' learning outcomes. In this regard, concept cartoon is widely recognized as an innovative strategy rooted in constructivism; however, its efficacy in enhancing conceptual understanding in science needs to be investigated in the Pakistani science classrooms. Thus, this study focused on exploring the efficacy of concept cartoons in enhancing students' conceptual understanding in selected science concepts on Science Achievement Test for Heat (SAT-H). For this study, quasi-experimental design (pre-and post-test control group) was used as a research methodology. A total of 65 students from grade VII participated in the study including comparison group (n=35) and intervention group (n=30). The Science Achievement Test for Heat (SAT-H) was developed and validated which was administered to both groups as pre-test (before intervention) and post-test (after intervention). During intervention, intervention group (lG) was taught with concept cartoons and comparison group (CO) was taught with standard teaching practices. The two groups were compared on overall performance on SAT-H, performance on SAT-H content domains (i.e. heat and temperature, methods of heat transfer) and performance on SAT-H cognitive domains (i.e. knowledge, application and reasoning) in both pre-test and post-test. Results of the study revealed that on pre-test, both groups were evenly matched on their overall performance (p>0.05). Similarly, no differences were found between two groups in all content domains (p>0.05). However, among three cognitive domains, performance of the two groups was found to be different on two cognitive domains favoring 10 for application (p<0.05) and CO for knowledge (p<0.05). Conversely, on post-test, both groups showed improvement, however, IG performed considerably better than CG with significant difference (p

خاتمہ کلام

حدود و قصاص سے متعلق شرعی قوانین موجود ہیں اور دنیا ان کے ثمرات سے مستفید ہو تی رہی ہے کیونکہ یہی قوانین صدرِ اسلام میں نافذ ہوئے ۔ بنو امیہ ، بنوعباس ، دولتِ فاطمیہ سے لے کر خلافت عثمانیہ تک اور ہندوستان میں بھی مغلوں نے انہیں قوانین کے ذریعے دنیا کو امن و امان فراہم کیا۔
مصنف اس بات کا اعتراف کرتا ہے کہ حدودوقصاص اور دیگر اسلامی قوانین کی تنفیذ کے لیے ریاست کا ڈھانچہ اسلامی و فلاحی ہو ۔ مسلمانوں کے اجتماعی نظام کی اصل اساس امرھم شورٰ ی بینھم ہی ہے اس لیے ان کے امراء و حکام کا انتخاب اور حکومت و امارت کا انعقاد مشورے سے ہی ہو۔ ریاست کے عاملین اور ججوں کا تقرر اسلامی طریقے کے مطابق ہو ۔ عاملین و ججوں میں یہ تمام خصوصیات پائی جاتی ہوں کہ وہ مسلمان ، آزاد ، عادل ، پاکدامن، بردبار ، ماقبل کے حالات سے باخبر ، عقل مند حضرات سے مشاورت کرنےوالے اور اللہ تعالیٰ کی راہ میں کسی ملامت کرنےوالے کی ملامت سے نہ ڈرنے والے ہوں ۔عدلیہ کے سامنے مقدمات پیش کر نے والے پولیس افسران ایماندار ہوں،تاکہ معاشرے میں نظم وضبط قائم کرسکیں ، قانون کو لاگو کر سکیں ، مظلوم کو انصاف دلوا سکیں اور مقدمات کے اندراج سے عدالت مجاز میں مقد مہ کے فیصلے تک وہ قانون اور مظلوم کا ساتھ دیں۔ وکلاءآزاد اور صحیح فیصلہ کرنے میں عدلیہ کی معاونت کریں۔ ریاست کے انتظام کو چلانے کےلیے چاہے وہ امیر المسلمین ہو ، جج ہو ، پولیس افسر ، وکیل ، سرحد کی حفاظت کرنے والا فوجی ان سب کی صحیح معنوں میں تربیت کےلیے اسلامی نظام تعلیم کا بندوبست ہونا ضروری ہے اور نظام تعلیم کے مقاصد خالصتاً اسلامی فلسفہ حیات سے اخذ کیے گئے ہوں ، پڑھنے...

Tillage and Stubble Management in Cereal Based Cropping System

Continuous cereal based crop rotation; inappropriate cultivation, burning and removing crop residues deteriorate soil physico-chemical characteristics and crop production in western plain of Pakistan. The objective of this study was to evaluate the effects of different tillage systems (TS) and corn stubble or residues management on soil physico-chemical properties, N dynamics and crop productivity. The study was conducted for two years at Cereal Crops Research Institute Pirsabak (34oN latitude, 72oE longitude and 288m altitude) Nowshera, Khyber Pakhtunkhwa, Pakistan. The treatments were laid out in a randomized complete block design with split plot arrangement having four replications in each year. The treatments of the experiment were three tillage systems (TS) i.e. reduced (10 cm); conventional (20 cm) and deep (30 cm) allotted to main plots, whereas the subplots were maize stubble management (SM) such as physical removal, burning and incorporation with and without N (120 kg ha-1) fertilizer application. Minimum tillage system had improved soil moisture retention (20.02 %), soil bulk density, soil mineral N (13.23 mg kg-1 soil) and total nitrogen (0.75 g kg-1 soil), and soil organic carbon (14.67 g kg-1 soil) compared to conventional and deep tillage system. Greater straw N (5.26 g kg-1 dry matter) and grain N (19.08 g kg-1 grain) content, straw N uptake (43.67 kg ha-1), grain N uptake (60.06 kg ha-1) and total N uptake (103.74 kg ha-1) was recorded in minimum tilled than conventional and deep tilled plots. Nitrogen indices like N use, N uptake and N utilization efficiencies, N harvest index and grain protein content were not affected by TS during both single years however, NHI (57.34%) and protein content (11.92 %) in grain was found higher over the years in minimum tillage compared to other tillage systems. Wheat phenology except days to emergence was not affected by different tillage systems however; early emergence was observed in minimum tillage rather conventional and deep tillage. Minimum tillage improved yield, yield components, wheat biomass and harvest index. Similarly enhanced emergence and greater tillers were observed in minimally tilled plots. Application of fertilizer N (120 kg ha-1) did not affect soil moisture content and bulk density however, soil organic carbon (14.91 g kg-1 soil), mineral N (13.31 mg kg-1 soil) and soil total N (0.77 g kg-1 soil) was xvii observed greater over the years while lower soil pH (7.56) and C/N ratio (19.33) was observed in fertilized plots compared to control plots. N uptake efficiency and N utilization efficiency was not affected by N application. Stubble incorporated (SI) plots had improved physico-chemical properties of soil compared to stubble removed and burnt plots. Incorporated stubble plots had resulted statistically higher results for N uptake efficiency (37.16 kg plant N ha-1/ kg soil available N ha-1) compared to stubble removed plots however, non-significant results were observed for N utilization efficiency among different stubble management practices. Nitrogen content in plant components (leaves, stem, spike) at pre and post anthesis stages, straw N, grain N at maturity, N uptake by straw and grain, and total plant N uptake was significantly improved in fertilized stubble incorporated plots compared to unfertilized and stubble burnt or removed plots. While significantly higher N use efficiency of wheat crop was observed in unfertilized and stubble removed plots compared to fertilized and stubble incorporated plots. N harvest index and grain protein of wheat was significantly affected by addition of 120 kg N ha-1 while incorporation of stubble had affected the later one only. Fertilization had enhanced phenological observations while no significant variations in days to phenological observations were recorded among SM practices. Greater average leaf area and leaf area index as well as pre and post anthesis dry matter (DM) production in various plant parts was observed in N mixed SI plots as compared to the rest of managed plots. N fertilization at the rate of 120 kg ha-1 and corn stubble incorporation prior to wheat sowing had also improved tillers m-2, plant height, grain yield, yield components, biomass, straw yield and harvest index over the years against unfertilized and stubble removed as well as burnt plots. Greater emergence m-2 was observed in fertilized plots only while similar lodging score was recorded in fertilizer urea mix stubble incorporated plots. It was concluded from the economic analysis that corn stubble incorporation with recommended dose of fertilizer N (120 kg ha-1) prior to wheat sowing had resulted higher value cost ratio (VCR;7.51) and net income (Rs. 157946 ha-1) compared to VCR (6.27) and net income (Rs.128622) obtained from control plots. Similarly SI plots had resulted greater net income (Rs. 154748 ha-1) compared to stubble removed plots (Rs. 132504 ha-1). Besides economic benefits stubble incorporation along with fertilizer N had also improved yield, nitrogen dynamics, dry matter production and soil quality parameters under reduced tillage in a continuous cereal based cropping system instead of stubble burning and removal.
