فن التقريب في العلوم والهندسة: كيف تخرج بالإجابات سريعاً؟
Conditions of Use:

Rating

الغرض من هذا الفيديو التعليمي هو أن يرى الطلاب كيفية التفكير بتحرر أكبر حول مسائل الرياضيات والعلوم. فأحياناً يكون الحصول على إجابة تقريبية في مدة زمنية أقصر بكثير هو أمر يستحق الوقت الذي تم ادخاره. ويستكشف هذا الفيديو آليات لعمل حسابات تقريبية سريعة وارتجالية، وليست فقط دقيقة على نحو مدهش وإنما أيضاً منيرة لبناء الحدس والبديهة في فهم العلوم. ويتطرق هذا الفيديو إلى الجبر 1 الخاص بالصف العاشر وكذلك إلى فيزياء أولى ثانوي، إلا أن المفاهيم التي يغطيها (السرعة، المسافة، الكتلة، إلخ) أساسية بشكل كافي ليفهمها الطلاب الأصغر سناً الذين لديهم معرفة بالعلوم. وفي حالة الرغبة، يمكن للمعلمين أن يحضروا بندولات ذات أطوال مختلفة، وأثقال للتعليق، وساعة مؤقت لقياس المدة الزمنية. ومن الأمثلة على أنواع التمارين داخل الفصل المدرسي خلال الفترات الفاصلة بين مقاطع الفيديو، أن: تطلب من الطلاب تقدير حاصل ضرب 29 x 31 دون آلة حاسبة أو ورقة وقلم؛ وكذلك تسأل الطلاب عن المقدار الذي يستطيعون فيه الاقتراب من الثقب الأسود دون أن يبتلعهم.

ان الغرض من هذا الفيديو التعليمي هو إظهار الطلاب لكيفية التفكير بحرية أكبر حول مشاكل الرياضيات والعلوم. ان الحصول في بعض الأحيان على إجابة تقريبية في فترة أقصرهو أمر يستحق الوقت الموفر. يستكشف هذا الفيديو تقنيات لصنع خلفيات تقريبية سريعة للمغلف الذي ليس فقط مستغرب من جهة الدقة، ولكنه أيضا منيرا لبناء الحدس في فهم العلم. يقترب هذا الفيديو من مستوى الصف العاشرالخاص بالجبر 1 ومن مستوى الفيزياء للعام الأول الثانوي، ولكن المفاهيم المتضمنة به (السرعة، المسافة، الكتلة، إلخ) هي أساسية بما يكفي لأن يستوعبها طلاب العلوم الأصغر سنا. إذا رغبت، بامكان المدرسين جلب بندول الساعة من مختلف الأطوال , الأوزان لتعليقه, و ساعة وقت لقياس الفترة. تتضمن الأمثلة على التمارين التي تمارس في الفصل فيما بين مقاطع الفيديو: سؤال الطلاب لتقدير 29 × 31 دون آلة حاسبة أو ورقة وقلم رصاص؛ وسؤال الطلاب عن ما مدى امكانية وصولهم الى الثقب الأسود بدون الانزلاق بداخله.

The Mission to Mars curricular unit introduces students to Mars the Red Planet. Students discover why scientists are so interested in studying this mysterious planet. Many interesting facts about Mars are revealed, and the history of Martian exploration is reviewed. Students will learn about the development of robotics and how robots are beneficial to science, society and the exploration of space. Details on engineers' involvement in space exploration are presented. Furthermore, students will learn how orbits allow astronauts to move from planet to planet and what type of equipment is used by scientists and engineers to safely explore space. Lastly, the specific details on and human risks for a possible future manned mission to Mars (and back to Earth again!) are discussed.
