Chương 3: Những kết quả bước đầu
Qua kì 1 năm học 2019 -2020 bằng việc ôn tập kỹ phần thì (Tenses), cho HS học thuộc lòng các câu ví dụ, kiểm tra và hướng dẫn các em làm bài tập trên lớp. Đa số HS ở các lớp do tôi phụ trách có thể làm các dạng bài tập các loại câu điều kiện một cách nhuần nhuyễn. Dưới đây là bản thống kê chất lượng bài kiểm tra 15 phút và 1 tiết lớp 10 và lớp 11 trong năm học 2019-2020

8. Các điều kiện cần thiết để áp dụng sáng kiến:
- Về phía giáo viên: Chuẩn bị giáo án chu đáo, trong khi giảng dạy cần vận dụng linh hoạt kĩ thuật dạy học, tùy vào đối tượng học sinh mà áp dụng ở mức độ khác nhau.
 - Về phía học sinh: Cần ôn lại các kiến thức về câu điều kiện đã học ở cấp 2. HS cần phải tích cực làm bài tập theo yêu cầu của giáo viên. 
9. Đánh giá lợi ích thu được hoặc dự kiến có thể thu được do áp dụng sáng kiến 
9.1.Để việc dạy phần mệnh đề điều kiện cho HS trung học phổ thông đạt hiệu quả cao trước hết chúng ta phải ôn tập, làm sao cho HS nắm được các thì tiếng Anh cơ bản – Việc làm này được tiến hành xuyên suốt quá trình dạy học. Tôi đã soạn và phát cho HS bản tóm tắt các thì . Cho HS học thuộc lòng các loại câu và giải thích được vì sao phải dùng thì đó. Đưa ra các tình huống để đặt câu. Mệnh đề chính phải khớp với mệnh đề phụ theo từng loại. Tôi khuyến khích và kiểm tra các em. Phát huy khả năng chia sẻ trong hoạt động nhóm vào 15 phút đầu giờ. Các học sinh yếu, kém được giao cho một HS khác giỏi hơn kềm cặp giúp đỡ.
9.2. Đánh giá lợi ích thu được hoặc dự kiến có thể thu được do áp dụng sáng kiến theo ý kiến của tổ chức, cá nhân: Hầu hết học sinh đều hào hứng với các hoạt động của giờ học. Đa số tích cực tham gia. Việc tìm hiểu bài học trở nên tự giác hơn. Giờ học sôi nổi và hiệu quả hơn.
