The primary school mathematics curriculum design included many aspects: * * 1. Problems ** 1. * * Teaching objectives ** - Under the influence of traditional concepts, teaching goals were often too singular. Most teachers focused on imparting mathematics knowledge, ignoring the students 'pursuit of personality and initiative to learn. The new curriculum standards emphasized the teaching process and methods, focusing on cultivating students 'ability to discover and solve problems from real life, communication and cooperation skills, and stimulating their enthusiasm for learning mathematics. 2. * * Teaching format ** - There was a lack of innovation. The new curriculum requires teachers to abandon the old model and enhance students 'learning autonomy and teachers' teaching innovation. Teachers should have the courage to break the convention when designing the curriculum, setting up ladder problems and combining examples to inspire students to solve mathematical problems. 3. * * Interesting aspects of the class ** - Some teachers did not understand the new curriculum concept well and blindly pursued the fun of the classroom. In the past, the primary school mathematics curriculum was relatively boring. After the new curriculum reform proposed interesting classes, some teachers spent too much classroom time setting up games, resulting in the students 'grades not improving, causing some teachers to think that classroom games were a waste of time. * * II. Steps to improve the efficiency of the curriculum ** 1. * * Creating a teaching atmosphere ** - The interest was the potential motivation to stimulate the enthusiasm of the students. Teachers should create a good mathematics teaching atmosphere when designing the curriculum, such as using multi-mode cross-cooperation such as situation teaching and question-guided teaching, and combining the characteristics of primary school students to teach. For example, when you know numbers, you can ask questions based on the number of popular animated characters. Students will be rewarded for answering correctly to stimulate interest. At the same time, teachers should strengthen emotional communication with students, pay attention to personality differences, encourage students to integrate into the teaching process, and play the main function. 2. * * Diverse teaching methods ** - Students were the center, and teachers played a guiding role. Teachers should fully explore the mathematical ideas in the teaching materials. On the basis of understanding the teaching materials, they should adopt various teaching methods, such as group discussion and inquiry learning, and permeate mathematical ideas. In addition, they should make full use of multi-media teaching and use the Internet to display boring and difficult content to improve teaching efficiency. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is an example of a biofilter course design manual: * * 1. Design background and goal ** Biological filter was an effective sewage treatment technology, which aimed to remove the impurities in the sewage through the action of microorganisms. The goal of this course is to design a biofilter system that meets specific water quality requirements and treatment volume. * * 2. Design basis and basic data ** 1. * * Waste Water Flow and Quality ** - It is necessary to clearly design the sewage flow rate (for example, Q = 12000 m3/d) and the water quality of the incoming water, including the concentration range of various indicators such as chemical oxygen demand (Biochemical oxygen demand (BOD5), total nitrogen (TN), total Kjeldahl nitrogen (KN), nitrogen dioxide, nitrogen dioxide, nitrogen nitrogen, and organic nitrogen (for example, COD5 <60 </strong>, BOD5 </strong></strong></strong>, etc.). 2. * * Craftsmanship Requirement ** - For example, when using the biological nitrogen removal process such as sublimation and dehydration, the technical requirements such as BOD5: TN> 4 must be met, and when the carbon source is insufficient, additional carbon sources (such as methanoi, acetic-acid, etc.) must be considered. * * 3. Selection of biofilter type ** 1. * * Comparisons between ordinary biofilter (low-load biofilter), high-load biofilter and tower biofilter ** - Ordinary biological filter had low hydraulic load and organic load, good purification effect, but occupied a large area and was easy to block. - The high-load biofilter could improve the hydraulic load by means of water return treatment and other measures to solve the blockage problem. The high load referred to the hydraulic load rather than the organic load. The treated water return had many functions such as thinning the concentration of the incoming water and preventing the blockage of the filter material. When the hydraulic load was less than the specified value, the concentration of the organic matter in the raw water was higher than 200g/L, or the treated water could not meet the water quality discharge standard, it needed to return. - The tower biofilter could make the sewage, the biological film and the air fully contact, the water flow turbulence was fierce, and the ventilation conditions were improved. - According to the sewage flow, water quality, treatment requirements and other factors, select the appropriate type of biological filter (for example, if the treatment water volume is large and the organic load is high in this design, the high-load biological filter can be considered). * * 4.
