Teaching computer programming is recognized to be difficult and a real challenge. The biggest problem faced by novice programmers is their lack of understanding of basic programming concepts. A visualized learning tool was developed and used by volunteered first-year students for two semesters. The purposes of this paper are: Firstly, to emphasize factors which directly affect the performance of our students negatively. Secondly, to examine whether the proposed tool would improve their performance and learning progression or not. This tool provides many features and enhancement which were presented to students as pre-lecture material. The results of adopting this tool were conducted using a pre-survey and post-survey questionnaire. As a result, students who used the learning tool showed better performance in their programming subject. arabic 9 English 74

تناقش الورقة دراسة قبول موظفي الحكومة وتصوراتهم لإدخال انظمة المصادقة الحيوية Biometric” “Systems Authentication في مكان العمل. وتقترح دراسة العوامل التي تؤثر على قبول الموظفين للتقنية الجديدة حتى تسهل تبني واعتماد إستخدام التقنية الحيوية “Biometrics “في تطبيقات الحكومة الإلكترونية المختلفة. للتحقق من قبول الموظفين و استخدامهم لانظمة القياسات الحيوية “Systems Biometrics.“ الدراسات تشير إلى وجود فجوة رقمية وثقافية كبيرة بين الوعي باستخدام الموظفين للتقنية والحلول المفضلة التي تروج لها الإدارة لاستخدامها في المصادقة“Authentication “علي معاملات الحكومة الالكترونية وانعدام الثقة في التقنية واحتمالات سوء الاستخدام. دوافع الإدارة تعكس حاجة المديرين للنظر في هذه المسؤوليات لتضييق هذه الفجوات. يبدو واضحا أن التغلب على مقاومة الموظفين للتغيير, من استخدام الطرق التقليدية الي توظيف تقنيات جديدة هي قضية أساسية تواجه تنفيذ الانظمة الحيوية للمصادقة. استنادا إلى البحوث نوصي بأنه يجب ان تتم عملية التوعية والتوجيه حول الانظمة الحيوية قبل إدخال هذه التقنية وتقديمها في اي منظمة.

Biometrics technologies have been around for quite some time and many have been deployed for different applications all around the world, ranging from small companies' time and attendance systems to access control systems for nuclear facilities. Biometrics offer a reliable solution for the establishment of the distinctiveness of identity based on "who an individual is", rather than what he or she knows or carries. Biometric Systems automatically verify a person's identity based on his/her anatomical and behavioral characteristics. Biometric traits represent a strong and undeviating link between a person and his/her identity, these traits cannot be easily lost or forgotten or faked, since biometric systems require the user to be present at the time of authentication. Some biometric systems are more reliable than others, yet they are neither secure nor accurate, all biometrics have their strengths and weaknesses. Although some of these systems have shown reliability and solidarity, work still has to be done to improve the quality of service they provide. Presented is the available standing biometric systems showing their strengths and weaknesses and also emerging technologies which may have great benefits for security applications in the near future.
