How to implement the sharing and analysis functions of answering questions in online answering

How to implement the sharing and analysis function of answer results in online answering requires specific code examples

In modern society, education has increasingly focused on cultivating students' comprehensive abilities ability, and answering questions is one of the important ways to evaluate students' learning outcomes. With the development of information technology, more and more educational scenarios are beginning to use online question answering for teaching evaluation. This method can not only improve the efficiency of answering questions, but also obtain more valuable information through data analysis.

During the online answering process, in addition to real-time assessment of students’ answering performance, another important function is the sharing and analysis of answering results. This function allows teachers and students to participate in the evaluation and discussion of answer results, thereby better deepening their understanding of the learning content.

Specifically, to realize the sharing and analysis of answer results in online answering, the following steps can be taken:

  1. Log in to the system
    Users first need to log in to the system with their username and password in the answering system. Each user can have different identities, such as students, teachers, or administrators, and the functions and permissions that different identities can access may also be different.
  2. Create Answer Questions
    Teachers can create questions in the system and set answer rules and time limits. Questions can include different types such as single-choice questions, multiple-choice questions, fill-in-the-blank questions, etc. Teachers can set them according to needs.
  3. Student Answers
    Students log in to the system within the specified time, select the corresponding answer questions, and then fill in the answers according to the requirements of the questions. The student's answer process will be recorded by the system and automatically saved after the answer is completed.
  4. Sharing of answer results
    After the answer is completed, teachers can view the students’ answer results and choose to share the results with students or other teachers. The method of sharing can be through a link, QR code, or directly sent to designated students or teachers.
  5. Answer Result Analysis
    Teachers can analyze and make statistics on students’ answer results. You can count information such as the correct rate, error rate, and answer time for each question, and you can also rank and compare students' answer scores. These analysis results can help teachers better evaluate students' learning status, identify students' weak points, and provide targeted teaching guidance.

Code sample:

The following is a simple sample code that shows how to use Python language to implement the sharing and analysis functions of answering results in online answering.

# 导入必要的模块
import pandas as pd

# 定义一个答题结果类
class AnswerResult:
    def __init__(self, question, answer):
        self.question = question
        self.answer = answer

# 定义一个学生类
class Student:
    def __init__(self, name):
        self.name = name
        self.answer_results = []

    def add_answer_result(self, answer_result):
        self.answer_results.append(answer_result)

# 创建题目和学生
questions = ["1 + 1 =", "2 * 3 =", "5 - 3 ="]
students = [Student("张三"), Student("李四"), Student("王五")]

# 假设学生的答题结果为
answers = {
    "张三": [AnswerResult(questions[0], "2"),
           AnswerResult(questions[1], "5"),
           AnswerResult(questions[2], "2")],
    "李四": [AnswerResult(questions[0], "3"),
           AnswerResult(questions[1], "6"),
           AnswerResult(questions[2], "2")],
    "王五": [AnswerResult(questions[0], "2"),
           AnswerResult(questions[1], "6"),
           AnswerResult(questions[2], "2")]
}

# 学生答题结果保存
for student in students:
    student.add_answer_result(answers[student.name])

# 答题结果分享
for student in students:
    print(f"{student.name}的答题结果:")
    for answer_result in student.answer_results:
        print(answer_result.question, answer_result.answer)

# 答题结果分析
df = pd.DataFrame(columns=["问题", "正确答案", "学生", "答案"])
for student in students:
    for answer_result in student.answer_results:
        df = df.append({"问题": answer_result.question,
                        "正确答案": "2" if "2" in answer_result.question else "其他",
                        "学生": student.name,
                        "答案": answer_result.answer}, ignore_index=True)

# 统计每道题的正确率
correct_rate = {}
for question in questions:
    count = df[df["问题"] == question]["答案"].count()
    correct_count = df[(df["问题"] == question) & (df["答案"] == df["正确答案"])]["答案"].count()
    correct_rate[question] = correct_count / count

print("每道题的正确率:")
for question, rate in correct_rate.items():
    print(question, rate)

The above code example demonstrates how to implement the sharing and analysis function of answering results in online answering. Through this function, teachers can more conveniently share answer results with students, and discuss and interact with students through result analysis to better promote students' learning progress.
