Computerized Assessment System for Ortho-phonemic Deficiency Profiling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current assessments for identifying ortho-phonemic difficulties in middle school students are not precise enough, failing to differentiate specific subskills and often require individual administration, which is time-consuming and unreliable, limiting the effectiveness of targeted interventions.
Innovation Solution
A computerized system that administers multiple tasks to assess students' knowledge and skills related to Grapheme-Phoneme-Correspondence (GPC) regularities, providing a detailed profile of strengths and weaknesses through an internet-enabled platform, allowing for efficient and reliable identification of specific deficiencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional assessments are administered individually by teachers based on observation, then some level of student evaluation is achieved, but the assessment is time-consuming and unreliable
Solution Approach 1:
The patent replaces the mechanical system of individual teacher observation and administration with a computerized automated assessment system. The computer administers multiple tasks, records responses, and automatically scores them, eliminating the time-consuming manual process while maintaining or improving assessment precision through consistent, objective scoring algorithms.
Solution Approach 2:
The assessment system enables self-service by allowing students to complete multiple assessment tasks independently on computers without requiring continuous teacher involvement. The system automatically scores responses and generates detailed profiles, freeing teachers from the burden of individual administration while providing precise, standardized assessments.
2Measurement precision
If conventional assessments are used, then general student competencies are measured, but specific ortho-phonemic deficiencies cannot be differentiated
Solution Approach 1:
The patent segments the assessment into multiple distinct tasks, each targeting specific ortho-phonemic skills such as grapheme-phoneme correspondence, phoneme blending, and phoneme segmentation. This segmentation allows the system to differentiate specific deficiencies by analyzing performance on individual tasks rather than providing only a general competency measure.
Solution Approach 2:
The patent adds dimensionality to the assessment by implementing a multi-task structure with various response types (multiple choice, open-ended, audio recordings). This dimensional expansion enables the system to capture specific skill deficiencies across multiple domains, transforming a single-dimension general assessment into a multi-dimensional diagnostic tool.
3Loss of information
If multiple tasks are administered to assess specific skills, then detailed student profiles can be generated, but the assessment system becomes more complex
Solution Approach 1:
The patent implements a universal computerized platform that can administer multiple different assessment tasks through a single integrated system. The computer serves multiple functions: presenting visual and auditory stimuli, recording various response types, scoring responses using standardized algorithms, and generating comprehensive profiles. This multi-functionality reduces overall system complexity compared to having separate systems for each task type.
Solution Approach 2:
The patent merges multiple assessment tasks and scoring procedures into a single integrated computerized system. By combining task administration, response recording, scoring, and profile generation into one unified platform, the system captures comprehensive student information without the complexity of managing separate assessment tools for each skill area.

AI summary
A method and tool to give a multi-dimensional profile of a student's individual difficulties regarding a rules-based system such as reading or literacy. A sub-set of rules of the rules-based system are selected. Tasks related to the rules are presented to the student via, for example, the internet. The tasks are varied according to at least a plurality of classifications of type of rule and a plurality of different task types. The sub-set of rules and number of classification and task types are limited to allow exposure of all tasks within a manageable assessment period. Data from student responses to the tasks, both accuracy and other attributes (e.g. word vs. non-word, speeded vs. non-speeded, and others) of responses, can be evaluated across tasks and classifications to give a quite specific picture or profile of the student's knowledge and skills regarding the rules-based system. This assists better and targeted intervention steps.
