Description

Technical Field

[0001] This utility model relates to the field of educational equipment technology, specifically to a teacher-side device for on-site examinations and on-site examination components. Background Technology

[0002] In current educational practices, particularly in fields such as horticulture and agriculture, plant field assessments face a series of challenges. Traditional field assessment methods rely on paper materials or simple image recognition, which not only fails to comprehensively test students' knowledge of real plants but also easily leads students to overlook the importance of field observation and identification. Specifically, existing technologies have the following shortcomings: During large-scale field assessments, teachers find it difficult to effectively monitor the location and behavior of all students, especially in open natural environments, where management becomes significantly more challenging; field exams lack unified assessment standards and precise positioning mechanisms, potentially leading to incorrect plant sample identification due to inaccurate positioning, failing to accurately reflect students' understanding of various plants; existing field assessments often rely on manual organization and supervision, requiring significant manpower and time investment at every step, from exam room setup and question allocation to post-exam scoring; during field assessments, the collection, transmission, and recording of plant information mainly rely on paper and pen or non-professional electronic devices, which hinders timely information sharing and makes it difficult to guarantee data integrity and accuracy; due to the limitations of the assessment methods, students may rely solely on memory rather than actual observation skills to complete the exam, reducing the practical significance of the assessment and students' learning motivation.

[0003] To address the aforementioned issues, there is an urgent need to develop a complete solution based on positioning and information technology to optimize the on-site assessment device, improve the efficiency and fairness of on-site examinations, and at the same time promote the cultivation of students' on-site observation and identification abilities.

Subsequently, the teacher selects multiple target information in the background information database, creates an examination route, and stores it. At the start of the examination, students randomly select an examination route through on-site examination student-end devices. The navigation module on the on-site examination student-end devices guides students to each plant location based on the latitude and longitude information uploaded by the teacher. After arriving, students answer questions by checking the numbered labels on the plants and the uploaded photos, and entering the plant names. The answers are stored in the student-end storage module through the student-end control module or uploaded to the background information data device in real time. The timing module ensures that the examination is completed within the time limit, and automatically submits the current answers after the time limit is reached. Finally, the backend data processing equipment automatically scores the answers based on the content, or transmits the answers to the teacher's device at the testing site. The teacher then judges the correctness of the answers and sends them back to the backend data processing equipment to generate the exam results. The backend data processing equipment then sends the exam results to the corresponding teacher and student. Simultaneously, the score data is stored in the backend data storage module for teachers to summarize and analyze the scores.
