Indian Ocean in World History
Conditions of Use:
Read the Fine Print
Rating

The Indian Ocean Basin is becoming an important topic in middle and high school world history and geography courses, but one for which there are few instructional resources. This web-based resource helps teachers incorporate the Indian Ocean into world history studies by illustrating a variety of interactions that took place in the Indian Ocean during each era. The material is assembled into an integrated and user-friendly teaching tool for students in upper elementary, middle and high school. It offers students the chance to investigate primary sources that illustrate historical interactions, helping them to become more adept at the analytical historical thinking skills that are required by virtually all state history standards today.

Length Scales in the Solar System
Conditions of Use:
Remix and Share
Rating

A dynamically simplified solar system is constructed from online data to explore the real solar system on many different scales.

The realistically scaled solar system is surprising because nothing is visible due to the presence of many different scales. That is why it is usually rescaled in animations or illustrations. This is nice but gives us a wrong sense of distances and sizes. This Demonstration is intended to show the solar system's different scales in their full glory.

Since it is hardly possible to see anything when the real scales are used, controls have been added to modify the sizes of the celestial bodies.

Maths and Islamic art & design
Conditions of Use:
Read the Fine Print
Rating

This resource provides a variety of information and activities that teachers may like to use with their students to explore the Islamic Middle East collections at the V&A. It can be used to support learning in Maths and Art. Included in this resource are sections on:

Principles of Islamic art and design
Pre-visit activities
Activities to do in the museum
Activities to do back at school
Islamic art explores the geometric systems that depend upon the regular division of the circle and the study of Islamic art increases appreciation and understanding of geometry. The use of these geometric systems creates a harmony among Islamic decorative arts and architecture, which is consistent with the Islamic belief that all creation is harmoniously interrelated.

Approaching an abstract subject in a concrete way provides a means of extending maths into other curriculum areas. The context of the Museum expands and enriches students' appreciation of the application of geometry in a cultural context and develops the sense of different cultural identities. Students have the opportunity to become familiar with the relationship between geometry and design and this can give confidence to students who have never seen themselves as 'good at art'.

Algebra students need practice determining equations of lines given a pair of points, or the line parallel or perpendicular to a given line through a given point. This Demonstration, along with guiding worksheets or a teacher presentation, gives students a chance to see the relationships between these lines and points.

فهم العلوم: كيف تعمل العلوم فعلاً
Rating

إن رسالة "فهم العلوم" هو أن يقدم مورد ممتع وسهل الوصول ومجاني يعمل على التعريف الدقيق بماهية العلوم وكيفية عملها فعلاً. إن المنهج العلمي شيق، إلا أن الشروحات القياسية غالباً ما تغفل عن الطبيعة الديناميكية للعلوم. وتؤثر العلوم فينا جميعاً كل يوم، لكن كثيراً ما يشعر الناس بأنهم منعزلون عن العلوم. إن العلوم هي مسعى إنساني مكثف، إلا أن العديد من التصويرات تخفي جوانب الشغف والفضول، بل وحتى المنافسات والمكائد، التي تميز كل المشروعات الإنسانية. يقدم "فهم العلوم" للمستخدمين نظرة من الداخل على المبادئ العامة والمناهج والمحفزات التي تندرج في كل العلوم. يتضمن هذا المشروع في رحمه محاولة لإعادة الاندماج مع العلوم، والتي تبدأ بإعداد المعلم وتنتهي بالفهم العام الأوسع للعلوم. وتضم الأهداف العاجلة للمشروع: (1) تحسين فهم المعلم لطبيعة العمل العلمي، (2) توفير الموارد والاستراتيجيات التي تشجع معلمي الصفوف من الحضانة وحتى السادس عشر على تدعيم طبيعة العلوم طوال ممارستهم لتدريس العلوم، (3) توفير مرجع واضح وغزير للطلاب وعموم الناس، والذي يصور المسعى العلمي بدقة. لقد جرى إنشاء موقع "فهم العلوم" بواسطة متحف متحجرات جامعة كاليفورنيا بمدينة بيركلي، وذلك بالتعاون مع مجموعة متنوعة من العلماء والمعلمين، وتم تمويله بواسطة المؤسسة الوطنية للعلوم1. علماً بأن "فهم العلوم" كان قد استلهم واستوحى فكرته في البداية من عملنا المتعلق بمشروع "فهم التطور" الذي أبرز حقيقة أن العديد من المفاهيم المغلوطة حول التطور تنبع من سوء فهم طبيعة العلوم. فضلاً عن ذلك، يشير البحث إلى أن الطلاب والمعلمين في كل المستويات الدراسية لديهم فهم منقوص لطبيعة ومنهج العلوم، الأمر الذي يمكن أن نعزوه إلى الفصول المدرسية حيث يتم فيها تدريس العلوم بوصفها عملية بسيطة وخطية ولا تتولد عنها أشياء. وهذا التصوير الكاذب والمُقفِر يجعل الطلاب ينفصلون عن العلوم، ويثبط الدعم العام لها، وربما يساعد على تفسير المؤشرات الحالية بأن الولايات المتحدة تفقد ثقلها العالمي في مجال العلوم. فحتى وأبعد من الاهتمام بصحة الاقتصاد الأميركي، فإن عامة الناس بداخلهم احتياج أصيل للتقييم النقدي للطروحات المتضاربة للدليل العلمي في وسائل الإعلام. ولكي يفعلوا هذا، عليهم فهم مواطن القوة والقيود والمناهج الأساسية للمشروع الذي أنتج تلك الادعاءات العلمية. يقوم "فهم العلوم" بخطوة هامة نحو الوفاء بهذه الاحتياجات.
