"It is better to die ten steps forward than to live half a step backward." On July 20, Chen Ruihui, deputy director of the people's Armed Forces Department of Chengguan District, Lanzhou City, told the story of the heroic battle of Chen Hongjun, a Gansu "hero defending the country and the border", before his death in the teaching competition for post training of political instructors organized by the Gansu military region, which aroused strong resonance among the officers and soldiers on the scene. In order to deepen the theme education focusing on "maintaining loyalty to the core and striving to build a strong army", the Political Work Bureau of the Gansu military region launched a teaching competition for political teachers' on-the-job training around "cultivating excellent teachers, strengthening teaching ability and creating excellent classes". In order to ensure the teaching quality, they organized personnel to plan as soon as possible, repeatedly study the teaching theme, carry out demonstration teaching, teaching evaluation and lecture, push the door to listen to the class for many times, and after primary selection, 15 political teachers were selected to participate in the teaching competition. "The ideological and political education courses participating in the teaching competition are well selected, well prepared, thoroughly explained, grounded, steaming and inspiring." According to the leaders of the Political Work Bureau of the Gansu military region, the themes of the 15 education courses cover strengthening ideals and beliefs, pursuing heroic footprints, strictly observing political discipline, strengthening war awareness, etc., which are rich in content and diverse in forms, forming a complete education system. The author observed and found that the teachers who participated in the teaching competition included both old political workers and new faces; There are not only commanders of military sub districts, cadres of the Ministry of people's armed forces, but also civilian personnel who have just joined the post. Teachers' different identities, positions and their own experiences enrich the content of education, enhance the pertinence of education, and narrow the distance between them and officers and soldiers. When teaching, teachers make full use of the innovative achievements of Ideological and political education, and the teaching methods are flexible and diverse. Some use the resident red resources to adopt the immersive teaching method, some adopt the situational teaching method based on their own experience, and others adopt the dialogue and exchange teaching method with paying tribute to the hero as the starting point, which is refreshing. Corporal Li Qiang said, "such an education class has thoughts, stories and connotations. It is closely related to the thoughts of officers and soldiers and the reality of work, and listening quenches thirst." "To promote learning by comparison and construction by learning, political teachers are forced to innovate teaching methods, create high-quality courses with temperature and grounding, and activate the spring water of Ideological and political education." Liu Dongfeng, political commissar of jinchangjun District, who participated in the competition, said. (outlook new era)
