随机方法(请说明由何人用什么方法产生随机序列):

由独立统计师(不参与教学及评估)使用计算机生成区组随机序列,区组长度设为4。按学生轮转批次(每批14人)进行整群随机分配,将批次整群随机分至两种教学顺序组(组1:肺炎-LBL→腹泻-PBL;组2:腹泻-PBL→肺炎-LBL)。随机序列密封保存,直至分组完成。

Randomization Procedure (please state who generates the random number sequence and by what method):

The random sequence was generated by an independent statistician (not involved in teaching or assessment) using a computer-generated block randomization method, with a block length of 4. Clusters (each rotation batch of 14 students) were randomly assigned to two teaching sequence groups (Group 1: Pneumonia-LBL → Diarrhea-PBL; Group 2: Diarrhea-PBL → Pneumonia-LBL). The allocation sequence was sealed and kept confidential until group assignment was completed.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

是,采用部分盲法: 1. 评估者盲(是):出科考核由未参与教学且不知晓分组信息的第三方教师评分。 2. 受试者盲(是):仅告知学生教学安排,不透露研究假设(即不告知两种教学方法分别属于试验组还是对照组)。 3. 研究者/教学实施者盲(不涉及):由于教学方法(LBL与PBL)在操作上差异明显,负责授课的教师无法对其所实施的教学方法设盲。 4. 数据分析者盲(是):统计分析阶段,数据库中的分组变量将使用代码(A/B)替代,分析者在完成主要分析前不知晓代码对应的教学方法。

Blinding:

Yes, partial blinding is used: 1. Assessor blinding (Yes): Exit assessments are scored by third-party teachers not involved in the teaching and unaware of the group allocation. 2. Participant blinding (Yes): Students are only informed of the teaching schedule, not the study hypotheses (i.e., they are not told which teaching method is experimental vs. control). 3. Investigator/teaching implementer blinding (Not applicable): Due to the obvious operational differences between LBL and PBL, the instructors cannot be blinded to the teaching method they deliver. 4. Data analyst blinding (Yes): During the statistical analysis phase, the group variable in the database is coded as A/B, and the analyst is not informed of the corresponding teaching method until the primary analyses are completed.

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

1. Time of public data availability: This is a retrospective registration study, and on-site implementation was completed in August 2025. According to the mandatory requirements for retrospective registration of ChiCTR, applicants must establish a project on www.medresman.org, upload the raw data, and complete public disclosure and review before retrospective registration can be granted. The raw data will be uploaded to the ResMan platform prior to the submission of the retrospective registration application and will be publicly disclosed after review. After data disclosure, the public can browse the data summary through the ResMan IPD sharing platform. For data download, interested parties must contact the researcher and provide a data use plan; access will be granted only upon approval. 2. Method for sharing IPD: The data will be uploaded and shared via the IPD sharing platform of the ChiCTR’s Clinical Trial Public Management Platform ResMan (www.medresman.org). This study adopts the "non-public but shareable" mode of the ResMan platform, meaning that after the researcher uploads the data and sets it as "non-public," the public cannot freely query the data. Interested parties may contact the researcher through the ResMan platform. Upon approval by the researcher and the Ethics Committee, a de-identified limited dataset will be provided. The scope of shared raw data includes: de-identified data on theoretical knowledge test scores, clinical case analysis scores, Big Five Personality Inventory scores, DASS-21 psychological stress scores, attendance rates, and teaching engagement data. No information that could directly identify individual students (such as names or original student ID values) will be included.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

一、病例报告表: 本研究的病例报告表采用电子CRF为主、纸质备份为辅的双轨模式: 1. 电子CRF: 通过医院教学管理系统(加密平台)在线填写。CRF包含以下模块:  - 基线数据:人口学信息、基线测试得分、中文版大五人格量表评分;  - 教学阶段数据:出勤记录、讨论发言频次、教案版本号;  - 结局数据:后测理论得分、案例分析得分、DASS-21心理测评结果。 系统设置逻辑校验功能,自动检测异常值(如得分超出设定范围、必填项缺失),确保数据录入的完整性和准确性。 2. 纸质CRF备份: 仅用于紧急情况(如系统故障),记录在统一印制的纸质CRF表上,填写后24小时内扫描上传至电子系统。纸质表格存档于带锁档案柜,保存期限3年,到期后碎纸机销毁。 二、电子采集和管理系统: 1. EDC系统: 本研究采用REDCap平台构建关系型数据库作为电子数据采集和管理系统。系统支持多中心数据收集、逻辑校验、双录入比对、数据导出等功能。 2. 数据采集方式:  - 自动化采集:测试成绩、出勤记录通过医院教学管理系统自动抓取;  - 人工录入:人格测评量表、案例分析评分由两名研究者独立双人录入,双人数据一致率需达到≥95%;  - PBL讨论录音:全程录音(经学生知情同意),转录文字后关联匿名ID存档。 3. 数据库管理与质控:  - 存储:加密服务器(等保三级认证),分三级权限管理(研究者可编辑、监察员仅查看、学生仅查看个人报告);  - 数据清洗:剔除缺失>20%的记录,对连续变量进行离群值修正(±3SD截断);  - 数据核查:每周随机抽查10%数据核对纸质与电子记录,100%关键字段(如测试得分)由独立数据监察员进行源数据验证(SDV);  - 数据备份:每日增量备份至异地灾备中心(广州与深圳双节点);  - 锁库条件:所有数据通过质控(缺失率<5%、双录入一致率≥95%)后,由数据管理员与统计师共同签署《数据库锁定声明》,锁定后禁止任何修改。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

I. Case Record Form (CRF): This study adopts a dual-track model: electronic CRF as the primary method with paper CRF as backup. 1. Electronic CRF: Completed online through the hospital's teaching management system (encrypted platform). The CRF includes the following modules:  - Baseline data: demographics, baseline test scores, Chinese version of Big Five Personality Inventory (BFI-44) scores;  - Teaching phase data: attendance records, frequency of discussion contributions, teaching plan version number;  - Outcome data: post-test theory scores, case analysis scores, DASS-21 psychological assessment results. The system has logic validation to automatically detect anomalies (e.g., scores out of range, missing required fields), ensuring data completeness and accuracy. 2. Paper CRF backup: Used only in emergencies (e.g., system failure). Data is recorded on printed paper CRFs, scanned and uploaded to the electronic system within 24 hours. Paper records are stored in locked filing cabinets for 3 years, then destroyed using a shredder. II. Electronic Data Capture (EDC) System: 1. EDC system: This study uses the REDCap platform to build a relational database as the EDC system. The system supports multi-center data collection, logic validation, double data entry comparison, and data export. 2. Data collection methods:  - Automated collection: test scores and attendance records are automatically retrieved from the hospital teaching management system;  - Manual entry: personality assessment scores and case analysis scores are entered independently by two researchers (double data entry), with an agreement rate ≥95%;  - PBL discussion recordings: fully recorded (with informed consent from students), transcribed into text and linked to anonymized IDs. 3. Database management and quality control:  - Storage: encrypted server (classified as Level III security protection), with three-level permission management (editable by researchers, viewable by monitors, personal reports viewable by students);  - Data cleaning: records with >20% missing data are excluded, outliers for continuous variables are corrected (±3SD truncation);  - Data verification: random 10% of data is checked weekly for consistency between paper and electronic records, 100% of key fields (e.g., test scores) undergo Source Data Verification (SDV) by an independent data monitor;  - Data backup: daily incremental backup to a remote disaster recovery center (dual nodes in Guangzhou and Shenzhen);  - Database lock: after all data pass quality control (missing rate <5%, double-entry agreement rate ≥95%), the data manager and statistician jointly sign the Database Lock Statement, after which no modifications are permitted.
