课程组织与结构设计

合理的课程结构能够提高学习效率和学生参与度。本文探讨最佳的课程组织方法。

课程层级结构

数据模型

const courseStructure = {
  courseId: 'CRS_001',
  title: 'Web 开发完全指南',
  description: '从基础到高级的完整 Web 开发课程',
  level: 'beginner', // beginner, intermediate, advanced
  duration: 120, // 小时
  modules: [
    {
      id: 'MOD_001',
      title: 'HTML 基础',
      order: 1,
      duration: 10,
      units: [
        {
          id: 'UNIT_001',
          title: 'HTML 简介',
          order: 1,
          lessons: [
            {
              id: 'LES_001',
              title: '什么是 HTML？',
              duration: 15, // 分钟
              type: 'video', // video, text, interactive, quiz
              content: {
                videoUrl: 'https://...',
                transcript: '...',
              },
            },
          ],
        },
      ],
    },
  ],
  prerequisites: ['基础计算机操作'],
  targetAudience: '想要学习 Web 开发的初学者',
};

模块设计

创建模块的最佳实践

function ModuleDesigner() {
  const [modules, setModules] = useState([]);
  const [currentModule, setCurrentModule] = useState(null);
  
  const createModule = (moduleData) => {
    const module = {
      id: `MOD_${Date.now()}`,
      title: moduleData.title,
      description: moduleData.description,
      order: modules.length + 1,
      duration: moduleData.duration,
      objectives: moduleData.objectives || [],
      units: [],
      assessments: [],
      resources: [],
    };
    
    setModules([...modules, module]);
  };
  
  // 计算模块完成度
  const calculateModuleProgress = (module) => {
    const totalLessons = module.units.reduce((sum, unit) => sum + unit.lessons.length, 0);
    
    // 从后端获取学生进度
    return {
      totalLessons,
      completedLessons: 0,
      progress: 0,
    };
  };
  
  return (
    <div className="module-designer">
      <div className="modules-list">
        {modules.map((module, index) => (
          <div key={module.id} className="module-item">
            <span className="module-order">{index + 1}</span>
            <h3>{module.title}</h3>
            <p>{module.description}</p>
            <div className="module-meta">
              <span>{module.duration} 小时</span>
              <span>{module.objectives.length} 个目标</span>
            </div>
          </div>
        ))}
      </div>
      
      <div className="module-editor">
        {currentModule && <ModuleForm module={currentModule} />}
      </div>
    </div>
  );
}

单元设计

单元内容组织

class Unit {
  constructor(title, description) {
    this.id = `UNIT_${Date.now()}`;
    this.title = title;
    this.description = description;
    this.lessons = [];
    this.duration = 0;
    this.resources = [];
    this.quiz = null;
  }
  
  addLesson(lesson) {
    lesson.order = this.lessons.length + 1;
    this.lessons.push(lesson);
    this.duration += lesson.duration;
  }
  
  addResource(resource) {
    this.resources.push({
      id: `RES_${Date.now()}`,
      type: resource.type, // pdf, article, link, code
      title: resource.title,
      url: resource.url,
    });
  }
  
  addQuiz(quiz) {
    this.quiz = {
      id: `QZ_${Date.now()}`,
      title: quiz.title,
      questions: quiz.questions || [],
      passingScore: quiz.passingScore || 70,
    };
  }
}

// 使用示例
const htmlUnit = new Unit(
  'HTML 基础',
  '学习 HTML 的基础知识和标签'
);

htmlUnit.addLesson({
  title: 'HTML 文档结构',
  duration: 15,
  videoUrl: 'https://...',
});

htmlUnit.addResource({
  type: 'code',
  title: 'HTML 代码示例',
  url: 'https://github.com/...',
});

htmlUnit.addQuiz({
  title: 'HTML 基础测试',
  questions: [
    {
      id: 'Q1',
      question: '什么是 HTML？',
      options: ['...', '...'],
      correctAnswer: 0,
    },
  ],
});

学习路径设计

个性化学习路径

function LearningPathBuilder() {
  const [pathOptions, setPathOptions] = useState([
    {
      id: 'path_1',
      name: '快速入门',
      description: '2 周快速掌握基础',
      duration: 14,
      modules: ['MOD_001', 'MOD_002'],
      intensity: 'high',
    },
    {
      id: 'path_2',
      name: '标准路径',
      description: '8 周详细学习',
      duration: 56,
      modules: ['MOD_001', 'MOD_002', 'MOD_003', 'MOD_004'],
      intensity: 'medium',
    },
    {
      id: 'path_3',
      name: '深入学习',
      description: '12 周深度掌握',
      duration: 84,
      modules: ['MOD_001', 'MOD_002', 'MOD_003', 'MOD_004', 'MOD_005', 'MOD_006'],
      intensity: 'low',
    },
  ]);
  
  const [selectedPath, setSelectedPath] = useState(null);
  
  return (
    <div className="learning-paths">
      <h2>选择你的学习路径</h2>
      
      <div className="paths-grid">
        {pathOptions.map(path => (
          <div key={path.id} className="path-card">
            <h3>{path.name}</h3>
            <p>{path.description}</p>
            
            <div className="path-info">
              <span>⏱️ {path.duration} 天</span>
              <span>📊 {path.intensity === 'high' ? '高强度' : path.intensity === 'medium' ? '中等' : '轻松'}</span>
            </div>
            
            <button onClick={() => setSelectedPath(path.id)}>
              选择此路径
            </button>
          </div>
        ))}
      </div>
      
      {selectedPath && (
        <PathDetail pathId={selectedPath} />
      )}
    </div>
  );
}

先决条件与推荐

课程关联

const courseGraph = {
  // 课程依赖关系
  dependencies: {
    'WEB_201': ['WEB_101'], // Web 201 需要完成 Web 101
    'WEB_202': ['WEB_101', 'WEB_201'],
    'REACT_301': ['WEB_202', 'JS_301'],
  },
  
  // 推荐课程序列
  sequences: [
    {
      name: '完整 Web 开发路线',
      courses: ['WEB_101', 'WEB_201', 'WEB_202', 'REACT_301', 'BACKEND_401'],
      totalDuration: 300,
    },
    {
      name: '前端开发专家',
      courses: ['WEB_101', 'CSS_201', 'JS_301', 'REACT_301', 'VUE_301'],
      totalDuration: 250,
    },
  ],
};

// 验证先决条件
function checkPrerequisites(student, courseId) {
  const required = courseGraph.dependencies[courseId] || [];
  
  return required.every(prereq => 
    student.completedCourses.includes(prereq)
  );
}

评估系统集成

模块评估

function ModuleAssessment() {
  const [assessments, setAssessments] = useState([
    {
      id: 'ASS_001',
      type: 'quiz', // quiz, project, presentation
      title: '模块 1 知识测试',
      weight: 0.3, // 占总成绩 30%
      passingScore: 70,
      retryLimit: 3,
    },
    {
      id: 'ASS_002',
      type: 'project',
      title: '完成项目',
      weight: 0.5,
      dueDate: '2025-12-20',
      rubric: [
        { criteria: '功能完整性', points: 40 },
        { criteria: '代码质量', points: 30 },
        { criteria: '文档', points: 30 },
      ],
    },
    {
      id: 'ASS_003',
      type: 'presentation',
      title: '项目展示',
      weight: 0.2,
      scheduledDate: '2025-12-22',
    },
  ]);
  
  // 计算最终成绩
  const calculateFinalScore = (scores) => {
    return assessments.reduce((total, assessment) => {
      const score = scores[assessment.id] || 0;
      return total + (score * assessment.weight);
    }, 0);
  };
  
  return (
    <div className="assessments">
      <h2>模块评估</h2>
      
      <div className="assessment-list">
        {assessments.map(assessment => (
          <div key={assessment.id} className="assessment-item">
            <h3>{assessment.title}</h3>
            <p>类型: {assessment.type}</p>
            <p>权重: {assessment.weight * 100}%</p>
            
            {assessment.type === 'quiz' && (
              <p>及格分: {assessment.passingScore} 分</p>
            )}
            
            {assessment.rubric && (
              <div className="rubric">
                {assessment.rubric.map((item, idx) => (
                  <div key={idx}>
                    {item.criteria}: {item.points} 分
                  </div>
                ))}
              </div>
            )}
          </div>
        ))}
      </div>
    </div>
  );
}
