1000-word essay model essay 1 research background: teacher evaluation is widely used in schools in China, and teachers give it to students unilaterally. Unilateral evaluation of teachers has the advantages of objectivity, fairness and efficiency, but it inevitably has the disadvantages of lack of communication with students, which can not fully mobilize students' enthusiasm and participation in running schools. This experiment aims to compare the advantages and disadvantages of self-evaluation and teacher evaluation, and then study the desirability of students' self-evaluation.
Research content: 1. Is there a difference between students' self-evaluation of oral English and teachers' evaluation? 2. If there are differences, what are the reasons? 3. What are the advantages of self-evaluation over teacher evaluation? 4. Is the second round of student evaluation close to the teacher evaluation?
Research methods:
1. Summary: After two weeks of training and ten weeks of two rounds of assessment, the assessment is completed by the cooperation of teachers and students. The assessment criteria include four parts, and each part is divided into five points. Through the comparison of two rounds of students' self-evaluation and teachers' evaluation, as well as the questionnaire survey of related experiments, the experimental results are reflected according to the difference between the survey results and the evaluation results.
2. Participants: Teachers and students from the School of Foreign Languages of Guangdong University, including girls 18, boys 10, 22 English majors and 6 non-English majors, all studied English for 6- 12 years before the experimental study.
3. Specific experimental process: A, ensure students know the evaluation methods and standards through evaluation training; B, illustrate the old through examples.
Teachers' timely feedback helps students adjust the evaluation criteria in time. C. Teachers' participation and timely guidance enable students to understand the correct and objective evaluation. D, in order to ensure the reliability of the experimental results, students have received evaluation training before evaluation. The correlation between the two evaluations was investigated by chi-square test table.
4. Auxiliary tools: scoring standard table, questionnaire survey and student feedback table.
Data collection: 1, the difference between the first round of teacher evaluation and students' self-evaluation reached 5.3 points, while the second round of evaluation was reduced to 1.4 2, and the correlation between the results of the first round and the second round of students' self-evaluation and the examination was 0.552 1 and 0.7938, respectively.
3, the p value is less than 0.05, which shows that the two evaluation results are different.
4. Students' feedback on the self-assessment questionnaire survey, 93% students think that students should participate in the assessment, and 765,438+0% students say that their assessment is based on the scoring standard.
Research results:
1. The scores of students in the first round of assessment are quite different from those of teachers, and students tend to give themselves lower scores. After the teacher's timely feedback and guidance, the self-evaluation in the second round of assessment is more objective and closer to the teacher's assessment score.
2. The feedback from the questionnaire survey can be withdrawn. Students tend to give themselves low marks because of the learning process, students are less inclined to give themselves high marks, and China's traditional thought of self-modesty.
3. Students' positive attitude towards self-evaluation can be obtained from the feedback of questionnaire survey.
Research conclusion: 1, students not only learned the scoring method in the process of self-evaluation experiment, but also saw their own improvements in the process of scoring classmates.
2. The experimental results show that students should be trained in self-evaluation and teachers should give students considerable feedback to help them improve. Students' personality will affect their grading results. For example, students with good grades will give themselves relatively low scores, while students with poor grades will give themselves higher scores.
4. A longer experimental process will produce more credible results.
1000-word composition model essay ii music under the rapid development of science and technology
Pop music originated in the west and was the product of19th century. It developed rapidly in the early decades of 20th century. Western pop music, especially that of developed countries in Europe and America, occupies an important position in the world. America is the most developed country of pop music in the world, and it is also the main birthplace of pop music. Nowadays, pop music forms all over the world are basically developed on the basis of American pop music.
In the development of more than one hundred years, realistic pop music has gradually developed into a music system different from traditional music and modern music. This is not popular music as understood by the public. It is also very academic, based on jazz harmony, Latin music rhythm, African music rhythm and modern arrangement technology. It is characterized by diverse styles, relatively complex rhythms and diverse timbres. Including all kinds of folk music, the development style is not limited.
With the rapid development of economy, science and technology, the perfection and popularization of network, communication and media, people's lifestyles and concepts have also undergone profound changes with the changes of society. The concept of "pop music" originated in the west. Pop music refers to pop music, including both pop songs and instrumental music such as jazz and rock music. The genre of pop music is not fixed. The popularity and spread of music are divided into time and space. First of all, in terms of time, the pop music styles in different historical periods are obviously different.
It's just Rainbow Leehom's "heartbeat", a pop music I like, and I love the MV and creation of this song. Heartbeat is a very special song among Leehom's songs. He abandoned the academic creation technique and started from his inner thoughts, not from the music theory. Melody and lyrics are natural, and his attitude towards feelings is expressed in just one sentence. It is a good song that people want to calm down and listen to in the noise. Every instrument of this song, including guitar, piano, bass and drums, was composed and played by Leehom. In the process of playing, Leehom often practices and plays again and again, hoping that this song can show the truest inner feelings through the purest manual performance. The songs on the new album are very powerful and macro, so they are very visual. Leehom specially invited his good friend photographer seamus from new york to Taiwan Province to take charge of all mv shooting. Seamus has made six films and other short films this year. He is a promising new photographer in Hollywood at present. Leehom hopes to help each MV create a different photography style and give it a more vital visual expression through seamus's natural light style photography.
Without the rapid development of modern science and technology and the perfect combination with music creation, how can many fans be fascinated? If there is no combination of MV and song, just enjoying this song is also a kind of enjoyment for girls, but it is not as direct as the way of presenting MV. That will touch our hearts even more. Maybe in my opinion, this is a more direct way to listen to songs. With the rapid development of science and technology, more and more high technologies are integrated into our side, just like the music around us. Music is a medium to accompany us to grow up, and now this medium will gradually become scientific and technological.
The development space of pop music is infinite, and the development of science and technology is endless, as long as science and technology are perfectly combined with music creation. Even ordinary original songs, if skillfully added with scientific and technological elements, are another kind of enjoyment. Therefore, the long-winged take-off of science and technology paved the way for the improvement of our living standards.
