Unlike formative assessments, which aim to improve learning during the process, summative assessments provide an overall measure of students' mastery of specific content or skills.Key Features of Summative AssessmentThere are several key features of summative assessment:1. Endpoint evaluation: Summative assessment is conducted at the end of a specified period, such as a unit or course. It provides a final evaluation of students' performance and determines their level of achievement.2. Outcome-focused: Summative assessments assess students' ability to apply acquired knowledge and skills. They measure the extent to which students have met specific learning outcomes or standards.3. High-stakes: Summative assessments often carry significant weight in students' final grades or certifications. They provide aquantitative measure of students' performance and act as a determinant of their academic success.4. Standardized formats: Summative assessments often utilize standardized tests, exams, or projects to evaluate students. This ensures consistency in evaluation and allows for comparisons across students, schools, or districts.Benefits of Summative AssessmentSummative assessment offers several benefits in the education system:1. Accountability: Summative assessments provide a measure of accountability for students, teachers, and educational institutions. They promote transparency and fairness in evaluating students' knowledge and skills.2. External benchmarking: Summative assessments allow for external benchmarking by comparing students' performance against predetermined standards or national averages. This helps identify areas for improvement and inform educational policy.3. Certification and selection: Summative assessments serve as an important criterion for certification, grade promotion, and college admissions. They provide a standardized measure to select and differentiate students based on their achievements.4. Long-term retention: Summative assessments require students to consolidate their knowledge and apply it to new situations. Thisfosters long-term retention and deep understanding of the learned content.Drawbacks of Summative AssessmentHowever, summative assessment also has some drawbacks:1. Limited feedback: Unlike formative assessment, summative assessment often provides limited feedback or opportunities for students to improve their learning. The focus on final evaluation may neglect individual learning needs and hinder a growth mindset.2. Test anxiety: High-stakes summative assessments can create test anxiety among students. The pressure to perform well may negatively impact students' motivation, well-being, and actual performance.3. Reduced focus on skills: Summative assessments often focus on evaluating content knowledge rather than real-world skills. This may result in a narrow assessment that does not adequately prepare students for future challenges.ConclusionIn conclusion, formative and summative assessments are two essential components of the education system, each serving distinct purposes. Formative assessment promotes ongoing feedback, personalized instruction, and active engagement, enhancing students' learning in the process. On the other hand, summative assessment provides a comprehensive evaluation of students'learning outcomes, ensuring accountability, benchmarking, and certification.

They are seen as an objective and efficient way to measure a student's knowledge and understanding of a subject. However, some argue that examinations are not the most effective method of evaluating students. This essay will explore both sides of the argument and provide a balanced analysis on whether examinations are indeed the best method of evaluation.Arguments in favor of examinationsOne of the main reasons why examinations are considered an effective method of evaluation is that they provide a standardized measure of students' performance. By testing students on the same material in the same format, examinations allow for a fair comparison of students' abilities. This helps educators identify students who are excelling in a subject as well as those who may need additional support.Examinations also encourage students to study and revise the material covered in class. The pressure of an upcoming exam motivates students to review their notes, complete assignments, and seek help from teachers or peers. This process not only reinforces learning but also helps students develop important study skills such as time management and organization.Furthermore, examinations are a practical way to assess a large number of students at once. In a school setting, where there may be hundreds or thousands of students, examinations provide a systematic and efficient way to evaluate students' progress. They also serve as a benchmark to measure the effectiveness of the curriculum and teaching methods.Arguments against examinationsDespite their advantages, examinations have received criticism for being too focused on memorization and rote learning. Critics argue that examinations often test students' ability to recall facts and information rather than their critical thinking or analytical skills. This can lead to a shallow understanding of the subject matter and discourage creativity and independent thinking.Moreover, examinations can create unnecessary stress and anxiety among students. The pressure to perform well on examscan have negative effects on students' mental health and overall well-being. In extreme cases, this can lead to burnout, depression, or other mental health issues.Another drawback of examinations is that they may not accurately reflect a student's true abilities. Some students may perform poorly in exam conditions due to factors such as test anxiety, illness, or personal issues. This can result in an inaccurate assessment of their knowledge and skills, leading to unfair outcomes.ConclusionIn conclusion, while examinations have their advantages as a method of evaluating students, they also have limitations that need to be considered. It is important for educators to use a variety of assessment methods, including assignments, projects, presentations, and discussions, to provide a more comprehensive evaluation of students' learning. Ultimately, the goal of assessment should be to support students' growth and development, rather than simply ranking them based on exam scores. By taking a holistic approach to evaluation, educators can better understand and support the diverse needs and abilities of all students.。

评价,鉴定英语Assessment and Evaluation in EnglishEvaluation and assessment are integral components of any learning process, particularly in the realm of English language education. They serve as vital tools for gauging student progress, identifying areas of improvement, and adjusting teaching strategies accordingly. This essay delves into the nuances of evaluation and assessment in English, exploring their significance, methodologies, and challenges.First and foremost, it is essential to understand the distinction between evaluation and assessment. While the terms are often used interchangeably, they have distinct meanings. Assessment typically refers to the process of collecting and analyzing data to measure student performance, often through tests, quizzes, or other formal means. On the other hand, evaluation involves a more comprehensive and often qualitative analysis of student learning, focusing on areas such as critical thinking, creativity, and communication skills.In the context of English language education, evaluation and assessment play a pivotal role. They help teachers identify students' strengths and weaknesses in areas such as reading, writing, speaking, and listening. This information is crucial for tailoring teaching strategies to meet individual needs and promote optimal learning outcomes.One of the key methodologies used in English language assessment is standardized testing. These tests, such as the TOEFL or IELTS, are designed to measure students' proficiency in English across a range of skills. While standardized tests provide a reliable and objective measure of student performance, they also have limitations. For instance, they often focus on discrete skills rather than the integration of language skills in real-world contexts. An alternative approach to assessment is the use of authentic materials and tasks. This method involves assessing students' ability to use English in real-world scenarios, such as reading comprehension of complex texts or writing essays on timely topics. Authentic assessment provides a more comprehensive picture of studentproficiency and encourages the development of languageskills that are relevant and applicable in real-life situations.Evaluation, on the other hand, often involves a more qualitative analysis of student work. Teachers may evaluate students' written assignments, presentations, or discussions, focusing on areas such as creativity, critical thinking, and the ability to communicate effectively in English. Evaluation also involves providing feedback to students, which is crucial for guiding their learning and encouraging further development.However, both evaluation and assessment in English face several challenges. One significant challenge is the diversity of student backgrounds and abilities. Teachers must be mindful of the varying levels of Englishproficiency among their students and adapt their assessment and evaluation strategies accordingly. Another challenge is the need to balance the demands of standardized testing with the promotion of authentic language use and higher-order thinking skills.To overcome these challenges, teachers can adopt a range of strategies. For instance, they can use a combination of formal and informal assessments to capture a more comprehensive picture of student progress. They can also incorporate a variety of tasks and activities into their classrooms to encourage authentic language use and foster a love of learning English.In conclusion, evaluation and assessment are essential components of English language education. They provide teachers with valuable insights into student progress and learning needs, enabling them to tailor their teaching strategies effectively. While challenges exist, teachers can overcome them by adopting innovative assessment and evaluation practices that promote authentic language use and the development of critical thinking skills.。

I. I NTRODUCTION Class imbalance is a phenomenon in which the class distribution1 is far from the uniform distribution. It appears in many machine learning applications such as fraud detection, intrusion detection, and so on [2], [3]. Most classifiers are designed to maximize the accuracy of their models. Thus, when learning from imbalanced data, they are usually overwhelmed by the majority class examples. This is the main cause for the performance degradation of such classifiers, and is also considered as one of ten challenging problems in data mining research [4]. For example, in fraud credit card detection, suppose that the data set has 999 legitimate transactions (majority class) and only 1 fraudulent transaction (minority class – the one we would like to detect). To maximize the accuracy, in this case, classifiers optimized for accuracy will classify all transactions as belonging to the majority class to get 99.9% accuracy. However, this result has no meaning because the fraudulent transaction is misclassified. Obviously, to evaluate the classifiers in this case, the accuracy metric becomes useless, and the area under the ROC curve (AUC) is commonly used instead [5], [6]. The AUC has been widely used to evaluate the performance of classifiers. Recently, [1] has shown that using the AUC is equivalent to averaging the misclassification loss over a cost

Abstract— Recently, researchers have shown that the Area Under the ROC Curve (AUC) has a serious deficiency since it implicitly uses different misclassification cost distributions for different classifiers. Thus, using the AUC can be compared to using different metrics to evaluate different classifiers [1]. To overcome this incoherence, the H measure was proposed, which uses a symmetric Beta distribution to replace the implicit cost weight distribution in the AUC. When learning from imbalanced data, misclassifying a minority class example is much more serious than misclassifying a majority class example. To take different misclassification costs into account, we propose using an asymmetric Beta distribution (B42) instead of a symmetric one. Experimental results on 36 imbalanced data sets using SVMs and logistic regression show that B42 is a good choice for evaluating on imbalanced data sets because it puts more weight on the minority class. We also show that balanced random undersampling does not work for large and highly imbalanced data sets, although it has been reported to be effective for small data sets.
ratio distribution which depends on the score distributions. Since the score distributions depend on the classifier itself, employing the AUC as an evaluation measure actually means measuring different classifiers using different metrics. To overcome this incoherence, the “H measure” was proposed, which uses a symmetric Beta distribution to replace the implicit cost weight distribution in the AUC. When learning from imbalanced data, misclassifying a minority class example (e.g, a fraud credit card transaction) is much more serious than misclassifying a majority example. Thus, we propose using an asymmetric Beta distribution such as beta(x; 4, 2) (called B42) instead of the symmetric one as in the H measure. Moreover, many papers have been published about the class imbalance problem, but there is still little insight on how skew class distributions affect the classifiers when learning from large and imbalanced data sets. Furthermore, as investigated in [3], there are two open problems for the future research in this area: The need for a standardized evaluation protocol and the need for uniform benchmarks as well as large data sets [7]. The contributions of this work are (1) to propose an evaluation metric for learning from ioduce large benchmark data sets for systematic studies on imbalanced data, and (3) to investigate the influence of class imbalance on the behavior of classifiers when learning from large data sets. The rest of the paper is organized as follows. Section II introduces the H metric followed by the proposed B42 metric; in session III, we summarize some common techniques that are usually used to tackle the class imbalance problem; section IV first presents the evaluation protocol and the data sets. Then, we analyze and compare the results of three metrics (B42, AUC, and H) followed by analyzing the behaviors of classifiers when learning from large and imbalanced data; and finally, section V concludes the article.
