Alternative conceptions are the ideas which children and adults use to explain various scientific concepts which do not match with the generally accepted scientific explanation of those concepts. The focus of this qualitative research study was to explore the alternative conceptions of science teachers and their origins about basic concepts of current electricity. The concepts were taken from the science curricula of classes VI and VII and mainly include the concepts about the nature and flow of electric current, conductors and insulators, electric current in a simple circuit and electric current in a series and a parallel circuit. The sample included six middle school science teachers from three private schools in Karachi. Three different tools were used to explore teachers' conceptions and their origins about the selected concepts. The tools were (a) observation of classroom teaching while current electricity was being taught, (b) two questionnaires namely Learning Experience Sheet' and Task Sheet', (c ) an in-depth interview session. Learning Experience Sheet helped me to investigate how teachers had learnt about current electricity. Classroom observations and the Task Sheet explored the teachers' existing conceptions about electricity. The interview sessions provided me with an opportunity to discuss with the teachers their ideas in detail about electric current and the origins of these ideas. Open ended questions and probes were mainly used in the interview. The data obtained from all these sources was analysed and it was found that middle school science teachers of my sample hold several alternative conceptions about the basic concepts of current electricity. Many of their alternative conceptions are similar to those of children. For example, the teachers believe that a battery is a store of electrons which gives a fixed amount of electric current to any circuit in which it is placed, charge is used up by electrical devices, and electric current constitutes of the electrons which are produced in the battery. This study also explored that teachers' own rote learning of science as students, textbooks, daily life experiences, and lack of hands on experiences in current electricity are the main sources of teachers' alternative conceptions.

ڈاکٹر میر ولی الدین

ڈاکٹر میرولی الدین
افسوس ہے کہ یکم دسمبر ۱۹۷۵؁ء کو نامور فلسفی و صوفی اور مشہور مصنف و معلم ڈاکٹر میرولی الدین صاحب نے اپنے وطن حیدرآباد میں انتقال کیا، وہ اسی (۸۰) کے پیٹے میں تھے، ایک سال سے ان کی علالت کا سلسلہ جاری تھا، مرحوم کی تعلیم جامعہ عثمانیہ حیدرآباد میں ہوئی، یہاں سے فلسفہ میں ایم۔اے کرنے کے بعد لندن تشریف لے گئے، بیرسٹری کی تعلیم کے ساتھ کیمبرج یونیورسٹی سے فلسفہ کی اعلیٰ ڈگری حاصل کی، ۱۹۳۳؁ء میں جامعہ عثمانیہ میں فلسفہ کے استاذ مقرر ہوئے اور پھر اسی شعبہ کے صدر ہوکر ۱۹۶۰؁ء میں ریٹائر ہوئے اور کئی سال سے خانہ نشین ہوگئے تھے، تاہم تصنیف و تالیف کا مشغلہ جاری تھا۔
ڈاکٹر صاحب نے اردو اور انگریزی میں بہت سی کتابیں یادگار چھوڑی ہیں، انگریزی اور عربی کی بعض کتابوں کے ترجمے بھی کئے ان کو دارالمصنفین سے بھی بڑا تعلق تھا، ایک زمانہ میں ان کے مضامین معارف میں برابر شائع ہوتے رہے، ان کی پہلی کتاب ’’فلسفہ کی پہلی کتاب‘‘ یہیں سے چھپی تھی۔ یہ ریپوپارٹ کی پرائمر آف فلاسفی کا اردو ترجمہ ہے جس کو انھوں نے جامعہ عثمانیہ کے سلسلہ نصاب تعلیم کے لئے تیار کیا تھا، ’’رسالہ اخلاقیات‘‘ کے نام سے بھی ایک کتاب میڑک کے نصاب کے لئے لکھی تھی، ’’مراقبات‘‘ ان کی اہم کتاب ہے، یہ بظاہر تو حزب و اور ادکی کتاب معلوم ہوتی ہے مگر نفسیات کے اس مسلمہ اصول کے مطابق کہ انسان پر جس قسم کے خیالات کا غلبہ ہوتا ہے، اسی قسم کے اثرات اس کے خارجی اور باطنی وجود میں بھی لازماً ظاہر ہوتے ہیں، انھوں نے یہ ثابت کیا ہے کہ دینی تعلیمات اور ایمانیات و عقائد پر پختہ یقین و ایمان نہ صرف مذہبی عقیدت کے لحاظ سے بلکہ نفسیاتی اصول سے بھی انسان کی...

Digital Marketing Dalam Menghadapi Volatility, Uncertainty, Complexity, dan Ambiguity (VUCA)

Penelitian ini bertujuan untuk mengetahui strategi digital marketing industri halal pada Business Center (BC) Halal Network International Herba Penawar Alwahida Indonesia (HNI-HPAI) Pekanbaru 4 dalam menghadapi Volatility, Uncertainty, Complexity dan Ambiguity (VUCA) di era society 5.0 dan untuk mengetahui tantangan yang ada di era si society 5.0 pada BC HNI-HPAI Pekanbaru 4. Penelitian ini merupakan penelitian lapangan dengan menggunakan pendekatan kualitatif. Informan penelitian berjumlah 3 orang. Sumber penelitian yang digunakan adalah sumber primer dan sumber sekunder. Hasil penelitian menemukan bahwa strategi pemasaran digital yang dilakukan adalah menggunakan media whatsapp dan juga memanfaatkan beberapa media website dan aplikasi digital yang telah disediakan oleh HNI pusat dan unofficial, dan juga BC HNI Pekanbaru 4 mengandalkan para mitra-mitranya dalam pemasaran di media digital. Pada kondisi uncertainty, dalam mengumpulkan informasi BC menggunakan sosial media, dan melakukan edukasi. Pada kondisi kompleksitas, kesulitan yang di alami yaitu masih kekurangan pengelola khusus dibagian sosial media seperti facebook (fb), dan Instagram (ig). Sedangkan pada kondisi ambiguity, sasaran HNI adalah para generasi milenial yang sudah mahir menggunakan media digital. Adapun tantangan yang ada di era society 5.0 ini adalah harus siap dengan kehadiran teknologi, aktif dan mampu mengelola sosial media, inovasi produk, dan terus mengupgrade skill di era society 5.0.

Enhancing Qos in 5G Networks Using Self Optimization of Radio Resource Management Parameters

Enhancing QoS in 5G networks using Self Optimization of Radio Resource Management Parameters The demand for high data rate mobile traffic is increasing tremendously as the world transcends into High Definition (HD) quality applications, video calling, streaming traffic, social media etc. To match these sky-rocketing user demands, increasing traffic and volatile radio environment, mobile networks are continually evolving and becoming more and more sophisticated. While, the trend of mobile networks has been towards an all IP flat network, the network Quality of Service (QoS) metric has shifted from simple voice services to providing high volume data services. The increased network complexity puts a high burden on operation and maintenance costs making the traditional methods obsolete. In this backdrop, the concept of Self Organizing Networks (SONs) was introduced in the 4G mobile network standard by the 3rd Generation Partnership Project (3GPP) to enhance network performance and reduce operational costs. SON is also a significant component in the upcoming 5G mobile standard and thus has received much interest by the research community. SONs behave like an intelligent living organism and adapt to changing environment, resources and traffic loads. Two areas that have a notable impact on network performance are, interference mitigation and coverage adaptation for load balancing and these are the main focus of this PhD research work. We have worked on finding and comparing different self-optimisation techniques based on network Key Performance Indicators (KPIs), to reduce network interference and balance traffic load in the context of SON. In particular, we have applied simple machine learning techniques of Stochastic Cellular Learning Automata (SCLA), simple Q-Learning and Artificial Neural Networks (ANN) QLearning in a fully distributed SON 5G environment with a unique information sharing model among cells, its neighbours and the network. This model is unique in the sense that it depends on a simple distance separation criteria instead of Radio Frequency (RF) environment to identify and define neighbours for information sharing. Interference reduction was done for femtocells, and coverage adaptation for load balancing was done using active antenna tilt model. Test results from network-based simulators based on 3GPP guidelines show that simple SON technique like SCLA adapt quickly, as compared to advance techniques like Q-Learning but are limited in capturing complex network scenarios. The reason being, simple Q-Learning techniques fail to swiftly adjust to changing environment conditions as the number of state variables grow. This is due to increased training time required to build a meaningful Q matrix. ANN showed promising results concerning agility and adaptability to complex changing environments. ANN has the inherent capacity to accept a large number of inputs, reduce the input dimension and adapt to changes as time grows. It is thus concluded, that simple machine learning techniques like SCLA are best suited for enhancing QoS in 5G networks where optimisation input variables are unavailable or unknown like in standalone Femtocell case. However, in scenarios where the numbers of input variable are known and readily available from the network, i.e. cooperative distributed environment, ANN gives better results.
