Overcoming the obstacles, reflecting on the teaching plan of the large classThe following is an example of a reflection on a large class lesson plan:
* * 1. Teaching objectives **
1. * * Target Achievement Status **
- In terms of promoting children to develop upper and lower limb strength and movement coordination through run-ups, vertical jumps, and obstacle jumps, most children could master the basic movement essentials after many practices, such as jumping after run-ups, supporting with both hands, lifting feet, and other movements, indicating that the goal was achieved to a certain extent. However, there were still a small number of children who had difficulty in coordinating their movements. It might be due to individual differences that led to their slow acceptance and mastery of motor skills.
- With regards to the goal of allowing children to overcome difficulties, constantly challenge themselves, and experience success and happiness, by setting obstacles of different difficulty and encouraging children to try many times, most children showed excitement and satisfaction after successfully overcoming obstacles. However, some children hesitated to challenge the higher difficulty obstacles due to fear, which reflected that there was still room for improvement in stimulating the challenging spirit of these children.
- In terms of cultivating children's willingness to participate in challenges and collective sense of honor, the team challenge segment could stimulate children's sense of competition, but the overall team cooperation and interaction could be further strengthened, such as encouraging each other and sharing experiences.
2. * * The rationality of the target setting **
- The overall goal setting was in line with the age characteristics and physical development needs of the children in the first class. Children in the first year of school were at the stage of rapid development of physical coordination and motor ability. Such goals could help improve their motor skills. However, the refinement of the goal could be more precise. For example, tiered goals could be set for children of different ability levels to better meet the development needs of all children.
* * 2. Teaching content **
1. * * Adaptability of content **
- The content of the course revolved around obstacle climbing, including the exploration of obstacles, the setting of obstacles of different difficulty, and the learning of movement essentials, which were closely related to the teaching objectives. Running, jumping, and crossing were challenging for the children in the first class, but at the same time, they could stimulate their interest. However, the variety of content could be increased appropriately. For example, some obstacle simulations related to life scenes could be included to make children feel more immersive.
2. * * Consecutive content **
- The teaching content was coherent. From the simple method of playing with the mat to exploring the climbing method, to the multiple challenges that gradually increased the difficulty, to the captain's challenge and finally the challenge that increased the difficulty, it followed the principle of going from easy to difficult and step by step. This arrangement helped the child gradually master the skills to overcome obstacles, but the transition between each step could be more natural and smooth. For example, when increasing the difficulty, more interesting situations could be used instead of simply telling the child.
* * 3. Teaching methods **
1. * * Method effectiveness **
- It adopted many teaching methods such as practice method, exploration method and demonstration method. The exploration method could stimulate the initiative and creativity of the children in the process of exploring the method of crossing the mat by themselves, so that they could find a suitable way to cross the mat in practice. The demonstration method was to demonstrate the essentials of the movements after the teacher summarized the child's climbing method. It could intuitively let the child understand the correct movements. However, in the application of the practice method, the teacher's individual guidance was not timely and in-depth enough for the children whose movements were not standardized. As a result, the movement problems of these children were not corrected in time.
2. * * Method is innovative **
- The overall teaching method lacked a certain degree of innovation. Although traditional teaching methods could achieve the basic teaching purpose, some new elements could be introduced, such as the use of multi-media equipment to display exciting videos of athletes crossing obstacles to stimulate children's enthusiasm for learning; or the use of gamification methods, such as dividing children into groups to carry out relay competitions over obstacles, to enhance the fun of teaching.
* * 4. Teaching process **
1. * * Teaching segment settings **
- The teaching segment was complete, including the warm-up, the basics, and the end. The warm-up part could prepare the child's body for exercise and avoid injury; the basic part could gradually improve the child's athletic ability through multiple challenging segments; and the relaxation activity at the end could help the child relieve physical fatigue. However, in the setting of the basic parts, the time allocation for each challenge segment could be adjusted according to the actual situation of the child. For example, if the child was slow to master a certain difficulty obstacle, the time of the segment could be extended appropriately.
2. * * Grasp the teaching rhythm **
- The teaching rhythm was relatively tight, but when the children were challenged, there would sometimes be temporary confusion due to sudden situations such as falling or emotional fluctuations. Teachers needed to better anticipate these situations and take countermeasures in advance to maintain a stable teaching rhythm.
* * 5. Child's performance **
1. * * Child participation **
- Most of the children showed a high degree of participation in the activities. They were full of interest in the activities of climbing over obstacles and actively participated in various challenges. However, there were some children who needed more attention and guidance from teachers because of their weak athletic ability or poor adaptability to new environments and challenges.
2. * * Children's reactions and gains **
- Judging from the children's reactions, after successfully crossing the obstacles, the children showed obvious joy and a sense of accomplishment, which indicated that they had gained a positive emotional experience in the activity. In terms of motor skills, most children could master the basic obstacle crossing movements, but the standard and proficiency of the movements still needed to be improved. At the same time, the children also experienced the importance of teamwork in the team challenge segment, but this sense of teamwork still needed to be further cultivated in future activities.
* * 6. Teaching improvement measures **
1. To develop a personal teaching plan for individual children, and to give more individual guidance during the practice process to help them overcome difficulties and improve their athletic ability.
2. In terms of teaching content, add more elements related to real life to increase the variety and interest of the content.
3. The new teaching methods introduced the use of multi-media resources and game-based teaching to stimulate children's interest and initiative in learning.
4. During the teaching process, the time allocated to each link was more reasonable, and preparations were made in advance to deal with unexpected situations to ensure the stability of the teaching rhythm.
5. To strengthen team building activities, in the activities to focus on the development of children's sense of teamwork and collective honor.

Radiating back clip for a Sonny cameraWhen a Sony-grade camera was used continuously with high intensity (such as continuous video shooting and long exposure photo shooting), it might have a heat problem. Because the micro-camera was compact, the LCD was always working, and most of them were equipped with five-axis anti-shake, the heat was theoretically greater than that of a single-lens reflex camera. The heat of the machine would affect the quality of the video file recording and long exposure.
As for the heat dissipation problem, there was a "back clip fan" that could be used as a cooling device to assist the cooling of the Sony camera without affecting its normal operation. In addition, there was also a semiconductor cooling camera cooler that was also suitable for many brands such as the Sony-branded camera. This cooler cooled down in seconds, controlled the temperature, and the fan was close to mute without affecting the sound effect. It was recommended to use it with the camera power bank. For example, the Xperia 1 IV Gaming Version released by Sony in September had an Xperia Stream back clip accessory. Although it was larger and had more functions than other back clips, it had some cooling and other functions.
