DT & Engineering Blog: DJI Zenmuse X7

Standard

The DJI Zenmuse X7 offers revolutionary features that redefine professional aerial cinematography. A Super 35 mm effective sensor size for video recording can shoot 6K CinemaDNG and 5.2K Apple ProRes at up to 30 FPS, as well as 3.9K CinemaDNG and 2.7K ProRes at up to 59.94 FPS (narrow FOV).

 

The X7 also introduces the DL-Mount, the world’s first aerial lens mount system to quickly switch among four available prime lenses (16, 24, 35, 50 mm), creating a completely integrated system with professional gimbals and drones such as the Inspire 2. For seamless editing, a new DJI Cinema Color System preserves accurate colors for easier post-processing. Reach new heights and capture scenes as you imagine them with the DJI Zenmuse X7.

Class Teaching

This week’s teaching forum was led by our geography Curriculum Leader, Ben Crockett.  Ben was getting frustrated with the lack of commercially produced revision resources available for his students, particularly ones that would support them with remembering the case studies.  He wanted to be able to provide high level instruction for his students beyond the classroom, that went beyond the bog standard BBC Bitesize videos and was of the same high standard that students have come to expect from their geography teachers.

To address this, he created a departmental ‘YouTube’ channel.  Ben and his team then created short videos of themselves creating and explaining case study diagrams, and started publishing them on the channel.  The videos also contain exam questions and model answers, narrated by a subject expert (their teacher).  During the videos, the teachers support metacognition by explaining their own thought process in the creation of the case study…

A common lesson format. A structure, not a straitjacket…

teacherhead

In my previous school we devised a common format for lessons through staff discussion. The aim was to support the process of embedding certain behaviour routines and expectations and, perhaps more crucially, some pedagogical practices.  This week a Headteacher told me they had borrowed the idea so I thought I would share it again.  This time I have updated it with reference to retrieval practice and made it generic for any school.

It’s not a straitjacket – you could teach in all kinds of ways within the structure. There is almost nothing you couldn’t do.  But a common format, agreed by staff,  does help to generate a common language and common routines across a department and school.  I recommend it.

Here’s the image:

DT & Engineering Blog: Omron Ping-Pong Robot

Standard

Soon after the development of the ping-pong robot began, Omron engineers were able to make the robot move the paddle based on the calculations of the sensor and controller.

But no matter how many times it tried, the robot kept missing the ball. It couldn’t even return the ball to the opponent. If a human player is playing with another human player, it is rather easy to maintain a ping-pong rally. However, an extremely high level of technology is required if a rally is to be maintained between a human player and a machine.

The ball a player hits is first detected by the sensor, which then calculates how it should be returned. The controller then controls the robot so as to hit the ball according to the calculated data. This control is extremely precise, with a resolution of 1/1,000 of a second.

DT & Engineering Blog: Axon Flex 2 HD Body Camera

Standard

Axon Flex 2 from Axon on Vimeo.

The Axon Flex 2 is a camera system incorporating an audio and video recording device. This camera is designed for use in tough environmental conditions encountered in law enforcement, corrections, military, and security activities. The Axon Flex 2 camera is designed to record events for secure storage,
retrieval, and analysis via Evidence.com services. The recorded events are transferred to your storage solution via the Axon Dock, or by using Evidence Sync software installed on a Windows computer.

The Axon Flex 2 camera has 2 operating modes designed to accommodate the needs of law enforcement, corrections, security, and the military. The default mode, or BUFFERING mode, provides pre-event buffering to capture activities that occur prior to the user activating the EVENT mode. In addition, the Axon View application enables playback of footage on a smart device for review prior to storing the data.

More questions = fewer pointless PowerPoints

Class Teaching

The focus of this week’s Teaching Forum is questioning, an essential element of the craft of teaching. I sat down with Alex Mohammed, assistant leader in science, to learn a bit more about how to do it successfully.

*

For Alex, questioning is the most crucial part of being a science teacher. It enables him to understand where his pupils are so that he can extend them even further. Alex has spent the last four years honing and improving two types of question: those he asks while he is modelling and explaining a concept, and those he asks to check understanding.

Let’s start with the modelling. Unlike many teachers, Alex usually introduces new concepts from a blank screen – he rarely relies on pre-designed slide-shows. While he models and explains these concepts with simple drawings and diagrams, he repeatedly questions the class, helping them to link and extend their knowledge.
