The assessment of planting dates and nitrogen fertilization is a vital and practical approach for predicting crop performance in terms of seed development, yield and yield components and quality improvement in all cropping system. A field experiment was conducted to evaluate the effects of four planting dates and four nitrogen levels on agronomical, physiological and qualitative parameters of two wheat varieties during 2008-9 and 2009-10. Wheat varieties Pirsabaq-2005 and Khyber-87 were planted on four different dates with 20 days interval from October 24th to December 24th with four nitrogen levels of 0,100,130 and 160 kg/ha at New Developmental Farm, University of Agriculture, Peshawar. The experiment was carried out in Randomized Complete Block Design (RCBD) having split plot arrangement. Planting dates individually or in interaction with nitrogen significantly affected the seed developmental profile, yield and yield components and seed quality parameters of both varieties. Early planting dates of October, 24th and November 15th performed better in all agronomical, physiological and qualitative parameters in both varieties. A steady decrease was observed in yield and yield components, physiological attributes and qualitative traits (germination and vigor) with delayed planting. Nitrogen application at the rate of 100 and 130 kg/ha gave maximum yield components, whereas further increase in nitrogen dose had an adverse effect on all yield, physiological and quality parameters. Split application has a profound effect over single application and improved the yield and quality (germination and vigor) of both varieties. Variety Khyber-87 performed better in early plant date of October,24th with the lowest dose of nitrogen (100 kg/ha), whereas the performance of variety Pirsabaq-85 was better in early and as well as in normal planting date along with the application of (100 kg N). Therefore, it is concluded from this study that farmer’s should practice/prefer early planting for obtaining maximum grain and biological yield at 100 kg N/ha as compared to late November and December sowing. Delayed planted crop treated with 160 kg N/ha had detrimental effects on crop performance in all yield and quality parameters (germination, seedling dry weight, electrical conductivity and field emergence).

STANDAR PENILAIAN ASPEK PSIKOMOTORIK PENDIDIKAN AGAMA ISLAM

Psychomotor assessment is characterized by the presence of physical activity and performance skills by students. Unlike the students 'cognitive assessment, psychomotor assessment is based on the actualization and implementation of students' understanding of the various subject matter that has been obtained in the classroom. In some of the subject matter, psychomotor assessment determines the success of a lesson. This article is a literature research. This article aims to find students' psychomotor assessment format in Islamic Religious Education subject matter. The results of this study conclude that the assessment of the success of learners is not only determined from the cognitive aspects, but also from the affective and psychomotor aspects. Standard psychomotor assessment is made different from the cognitive assessment, that is by way of describing the test scores. Psychomotor assessment should be held by direct observation of learners, can not only practiced by written tests.  

Mathematics Teaching and Learning Practices at Secondary Level in Public and Private Schools of Pakistan

The aim of the study was to investigate the mathematics teaching and learning practices of secondary school teachers and to identify the gap between current mathematics teaching practices in Pakistan and best teaching practices suggested by the literature. In order to attain this aim, the researcher selected a sample of 1000 secondary school students at secondary level and 100 teachers teaching. The sample was taken in two stages. In first stage 25 public male schools and 25 public female schools were selected. Similarly 25 private male schools and 25 female private schools were also selected. Ten students from each of the sample schools were selected by using systematic random sampling technique. The study was mixed-method in nature and followed a concurrent research design in which both qualitative and quantitative data collection and analysis went parallel and the findings complement each other. The data for qualitative part were collected through semi-structured interviews of teachers and video-recorded classroom observation of students while the quantitative data were collected with the help of two survey instruments one for students and the other for teachers. The qualitative part was analyzed with the help of content analysis technique and the quantitative part with descriptive and inferential statistics. The reliability coefficient derived in a pilot study indicated that surveys were reliable enough to be used in the detailed study for data collection. The findings indicated serious gap between the current and perceived teaching and learning practices. It was discovered that teachers do talk about best practices but were not willing to apply those as they have their own many reasons for not doing so such as overworking, limited material resources and overcrowded classrooms. It was also found that the teachers did not even know what classroom practices have been recommended in educational policy documents and national curriculum of mathematics. It was pointed in survey that discussion and demonstration method are highly being used by the teachers whereas the classroom observations revealed that teachers used drill and practice method often. Further the teachers also claimed during the interview that drill and practice method is the best method for teaching and learning mathematics at secondary level. The teachers give guide books to students for memorizing various concept and subsequent drill. Although many teachers preached for conceptual understanding of mathematic yet it is lacked in classrooms. Problem solving technique of teaching is claimed to be a best and effective practice cum standard specified in National Curriculum Mathematics (2006) the data has shown that this practice is rarely used in the mathematics classrooms. It is concluded that the Pakistani mathematic secondary school teachers do not use many of the best mathematic teaching practices suggested by the literature. It was also observed in study that some of the best mathematic teaching practices are being used in private schools which are illustrated in teacher survey. But in students’ survey public school students have better perception of teaching and learning practices then private school students which is also observed in qualitative data. It has been recommended that the teachers may be oriented to use best mathematic teaching practices in their secondary school classrooms in order to develop deeper conceptual understanding among the students. Further the teachers may also be provided opportunities to develop their own knowledge and understanding of the recommended mathematics teaching practices as suggested by the national education policy and curriculum documents. It is further recommended that the future research may be conducted in order to explore how pre- and in-service training prepare secondary school mathematics teacher for the use of best mathematics teaching practices.
