Identifying Student Learning Styles

Date : June 2022

Everyone learns and understands concepts in different ways. Whereas one student may prefer to read about a concept and engage in solving practice questions on the concept, another student may prefer to watch a video and jump into taking a test on it. At Embibe, we have over 10+ years of data on students interacting with content and questions on the platform. We are constantly mining this data to discover surprising insights into student behaviour. Student learning style identification is….

Extracting Semantic and Context Information from Images and Equations

Date : June 2022

A vast majority of academic content includes information that is locked in images, equations, and symbols. The challenging problem of extracting semantic and contextual information from images and equations is very closely related to the problem of automated ingestion of content from unstructured data sources. Extracting semantic information from images is still a domain-dependent hard task requiring large datasets, complex machine vision, and deep learning approaches. Extracting meaningful information from images and equations is a domain-dependent task requiring a comprehensive understanding….

Automated Evaluation of Free Text Answer based Questions

Date : November 2021

A vast majority of competitive exams require the participants to solve objective-type questions, like questions that require one or more correct answers to be selected from a given set of answer choices or questions for which participants have to enter a numerical value. Evaluation of tests that are based on objective-type questions is quite straightforward. However, there are many exams, for example, board exams, which include questions with free-text answers. Evaluation of free-text answers is still an open research problem….

Smart Tagging – Towards Intelligent Content

Date : November 2021

The online evaluation used to assess a student’s understanding of concepts requires the questions used in the evaluation system to be tagged with concepts and other metadata like difficulty level, the time needed to solve, skills etc., that can be used to identify concepts the student is weak at or the level of her understanding with respect to that content. Typically, metadata tagging is performed manually by expert faculty. However, this is prohibitively expensive when a large dataset of questions….

Effects of Student Behaviour on Learning Outcomes

Date : November 2021

Academic Success is an established term in education and assessment that has undergone many changes. While some define ‘academic success’ in terms of standard measures like grades in a series of exams, others are inclined to use the term broadly. There has been a rapid expansion of studies to identify measures that show academic success is not just the marks obtained in an exam but also the learning and holistic development of a student, including improvement in a student’s attitude….

Embibe Score Quotient: Machine Learning for Outcomes Improvement

Date : November 2021

We believe measurability lies at the heart of improvement — what can be measured can be improved. Embibe Score Quotient is a numeric parameter that captures a student’s ability to score in an exam. The Embibe Sqore Quotient has the following characteristics: Reflective: Embibe Score Quotient should reflect a student’s potential based on latent attributes of the student’s performance. Predictive: It should be predictive based on the current trend of a student’s performance. Robust: A bad or good test should….

When we say students can solve unlimited questions on Embibe’s platform, we mean it. Embibe has a large dataset of questions available for students to practice on or to take assessment tests. However, ingesting these questions into the system is tedious and time-consuming. Historically, this dataset of questions was prepared by human data entry operators who would source questions from various freely available question sets on the internet or via tie-ups with our partner institutions. They would manually type out….

Building the Learning Outcomes AI Stack

Date : November 2021

Embibe has been a data-driven, data-focused, data-hungry company right from its inception, having understood very early that data was the key ingredient in being able to personalise education for every student at scale. And yet, data alone completes only half the picture. The personalisation of education using technology is a challenging problem that requires the interplay of advanced algorithms that can leverage enormous amounts of data across multiple sub-domains. At Embibe, we believe leaders are not born; they are crafted….

Intelligent Test Generation

Date : November 2021

When it comes to assessing students, test paper-based evaluation remains the most popular method across the world. A test paper aims to evaluate a large population, judge them on their academic ability and classify them into different ability bands. Hence, the test paper must incorporate questions with various discrimination factors, syllabus coverage, and difficulty variations. In the absence of any commercial application to generate high-quality tests automatically that match the level of the exam being tested for, test generation has….

Intelligent Search for Personalized Education

Date : November 2021

When it comes to delivering information that users are seeking, there are broadly two user experience paradigms. The first one involves a well-crafted, menu-based navigation system. The second is Search which serves content based on user queries. Search is a far superior method by which we seek online information today. While the menu-based system iteratively leads the users to the exact information they are looking for, the limited number of menu options makes it a less feasible option, especially when….

At Embibe, we help students improve their scores in standardized examinations by incorporating insights and models from learning theory and education research through item response theory models. One widely used model named Item Response Theory[1, 2] predicts a student’s likelihood of answering a question correctly by estimating the student’s skill or ability level and the difficulty level of the question being attempted. It was first proposed in the 1960s, and many variants of this exist today, such as the 1PL….

Tests are learners’ most preferred assessment techniques to measure performance against the targeted learning outcomes through deep learning-based methods. So, tests must be fair and effective to identify students’ learning gaps and boost students’ learning. The ability of a test to meet these goals is an aggregation of how relevant each question of the test is. Thus, the reliability of a test can be increased by item analysis, where students’ responses for each question or item are utilized to evaluate….

Introduction Embibe’s Knowledge Graph (KG) is a curriculum-agnostic multi-dimensional graph that consists of 75,000+ nodes. Each node represents a discrete unit of academic knowledge, also called concepts. The Knowledge Graph also has hundreds of thousands of interconnections (relations) between the nodes showing how concepts are not independent but are instead related to other concepts. The interconnections between nodes are assigned a type based on the kind of relationship that exists between them. Incomplete knowledge graphs and missing relationships have been….
