Intelligent Tutoring System of Linear Programming

There is a growing technological development in intelligent teaching systems. This field has become interesting to many researchers. In this paper, we present an intelligent tutoring system for teaching mathematics that helps students understand the basics of linear programming using Linear Program Solver and Service for Solving Linear Programming Problems, through which students will be able to solve economic problems. It comes down to determining the minimum or maximum value of a linear function, which is called the objective function, according to pre-set limiting conditions expressed by linear equations and inequalities. The goal function and the limiting conditions represent a mathematical model of the observed problem. Working as a professor of mathematics in high school, I felt the need for one such work and dealing with the study of linear programming as an integral part of mathematics. There are a number of papers in this regard, but exclusively related to traditional ways of working, as stated in the introductory part of the paper. The center of work as well as the final part deals with the study of linear programming using programs that deal with this topic.

A Fuzzy Expert System Architecture for Intelligent Tutoring Systems:A Cognitive Mapping Approach

An Intelligent Tutoring System (ITS) is a computer based instruction tool that attempts to provide individualized instructions based on learner’s educational status. Advances in development of these systems have rose and fell since their emergence. Perhaps the main reason for this is the absence of appropriate framework for ITS development. This paper proposes a framework for designing two main parts of ITSs. Besides development framework, the second main reason for lack of significant advances in ITS development is its development cost. In general, this cost for instructional material is quite high and it becomes more in ITS development. The proposed method can significantly reduce the development cost. The cost reduction mainly is because of characteristics of applied mapping techniques. These maps are human readable and easily understandable by people who are not aware of knowledge representation techniques. The proposed framework is implemented for a graduate course at a technical university in Asia. This experiment provides an individualized instruction which is the main designing purpose of the ITSs.

A Study on Human-Computer Interaction Mechanism in an Intelligent Tutoring System

Discussion is a common and important learning process.Involvement of a virtual agent can provide adaptive support for the discussion process.Argumen-tative knowledge construction is beneficial to learners’acquisition of knowledge,but the effectiveness of argumentative scaffolding in existing studies is not consistent.Based on an intelligent discussion system,a total of 47 undergraduate students took part in the experiment and they were assigned to three different conditions:content-related plus content-independent scaffolding condition,content-related scaffolding condition,and the control condition.Under the content-related and content-independent scaffolding condition,the computer agent provided an idea from semantically different categories(content-related scaffolding)according to the automatic categorization of the current contributions,and further inquired the participants about their attitudes and reasons(content-independent scaffolding).Under the condition of content-related scaffolding condition,the virtual agent only provided semantically different viewpoints.Under the control condition,the subjects expressed their opinion independently without the participation of the virtual agent.Findings revealed that compared with the control group,when the virtual agent provided semantically different ideas(content-related scaffolding),the discussion breadth(number of categories)was improved and the subjects felt that they had a more comprehensive understanding of the problem.Compared with the content-related scaffolding condition,when the virtual agent provided semantically different ideas and further asked about the attitudes and reasons,the subjects expressed more agreement with these views,but mentioned fewer categories during the discussion.This study suggests that the content-related scaffolding can facilitate the cognitive processing effect relevant to the topic of discussion.When the content independent scaffolding is added,it can promote the argumentative processing,but may have a negative effect on the cognitive processing related to the topic discussed.

Variegated Roles of and Relationships Between Private Tutoring and Schooling: Insights From the State of Maharashtra, India

Purpose:The relationship between private tutoring(PT)and mainstream education is among the complex themes characterizing PT discourses in the literature.This study examined the complications of practices and processes in tutoring and schooling to elucidate different roles played by PT and its relationship with mainstream education.Design/Approach/Methods:This study used qualitative data from a diverse set of 37 PT providers from the State of Maharashtra,India,to delineate their roles and explore their relationship with schooling in this context.Findings:The classification of PT providers roles into complementary,accommodating,competing,and substitutive ones demonstrated a diverse range of relationships between PT and mainstream education.Further analysis showed that these relationships are dynamic in nature,and the boundaries between them are blurred.Originality/Value:Research in the field of PT has been consistently pointing toward a perplexing mixture of positive and negative outcomes resulting from its relationship with mainstream education.This study transcended the positive vis-a-vis negative binary approach by contributing to the deeper understanding of PT relationships.Furthermore,it exemplified how future studies can disentangle the complexities of such relationships by deploying flexible,context-specific theoretical approaches.

Complexity of the Contexts:Features of Private Tutoring and Units for Comparison in the GCC Countries of the Middle East

Purpose:Private supplementary tutoringwidely known as shadow education because of the ways in which it mimics regular schooling-is increasingly visible across the globe.The Middle East is no exception,though the phenomenon has received relatively little attention in the English-language literature.This article maps some key features of shadow education,identifying ways in which contextual forces have shaped it.Design/Approach/Methods:The article focuses on patterns across and within the six members of the Gulf Cooperation Council(GCC),namely Bahrain,Kuwait,Oman,Qatar,Saudi Arabia,and the United Arab Emirates.It draws on literature in both Arabic and English and shows the value of multipleunits of comparison.Findings:Private tutoring has a long history as a significant phenomenon in some GCC countries,but in others developed more recently.Some governments have had active policies to dampen the phenomenon,but with little success.Factors in the complex dynamics include social,economic andcultural forces.OriginalityValue:The article assembles literature from around the region,noting both commonalities and diversities among GCC members.It contributes to the global literature by providing the regional mapping from this specific part of the world and by showing comparisons with other world regions.

Researching Forms of Shadow Education:Methodological Challenges and Complexities of Private Supplementary Tutoring in Myanmar

Purpose:The growing literature on private supplementary tutoring,widely known as shadow education,addresses multiple dimensions and roles.However,many studies inadequately capture the diversity and implications of different forms of tutoring.This paper examines these matters in Myanmar,highlighting complexities and ambiguities in descriptors and in the nature of provision.Design/Approach/Methods:Using a mixed-methods design,this study was conducted in Mandalay Region and Chin State.The data were obtained from interviews with I10 Grade II students,34 high school teachers,30 parents,29 private tutoring providers,and two private school owners.Findings:The article categorizes tutoring forms based on their styles and orientations,particularly lecture-type teaching and homework supervision by guides,class sizes,durations of fee-charging(e.g,annually),the number of subjects taught per tutor,and tutoring locations.The study brings the topic out of the shadows for clearer analysis of the phenomenon and thus for assessment of its implications.OriginalityNalue:The study makes a methodological contribution to the wider picture by demonstrating the need for greater clarity and precision in the national and international comparative literatures.It also underscores shortcomings of predetermined categories in questionnaires and the value of qualitative interviews.

The Cause of Institutionalized Private Tutoring in Korea:Defective Public Schooling or a Universal Desire for Family Reproduction?

Purpose:In Korea,private tutoring is considered a social evil that damages the capacity of public schooling and undermines social justice.Although the government has implemented various policies to reduce private tutoring,ranging from improving the quality of education to providing"quasi-private tutoring"programs and regulating the shadow education market,total spending on private tutoring has continued to increase.This study examines a little noticed but important cause of institutionalized private tutoring in Korea.Design/Approach/Methods:The study employed a socio-ecological perspective to analyze both education and socio-structural factors.An extensive review of the government's private tutoring reduction policies and related literature was conducted.Findings:Private tutoring functions as a means by which parents can help their children compete for admission to prestigious universities and pass on wealth and social status to their children.Participation in private tutoring has become a social norm that is taken for granted.The root causes of institutionalized private tutoring lie in both educational and socio-structural factors.Originality/Nalue:The study suggests that government policies,when ignoring the long-established"grammar"of parents about children's education,may either end in failure or produce unintended consequences.

Level of Implementation of Seasonal Malaria Chemoprevention in Children Aged between 3 to 59 Months in Koza, Far North Region of Cameroon

Background: Seasonal Malaria Chemoprevention (SMC) is a strategy put in place by World Health Organisation (WHO) to fight against malaria in zones of high seasonal malaria transmission since the year 2012. This strategy has been implemented in the Far North and North regions of Cameroon since the year 2016. Despite the implementation of this program the number of cases and deaths from seasonal malaria among the under 5 seems to be rising in Koza health area. Objective: To determine the level of implementation of the SMC Program and its impact on the mortality of children aged 03 to 59 months during the season of high transmission. Methods: This was a community-based cross-sectional and 7-years retrospective study. Data was surveyed for 3 months in 3 health areas of Koza health area. Data were collected and typed in Kobo collect, cleaned in MS Excel and analyzed in SPSS version 25 to come out with descriptive statistics. Results: Among the 172 households, female children were mostly represented 99 (57%) The age group mostly represented was 2 years. The population knowledge on SMC’s overall score was above average. The overall coverage rate (4 cycles) was 84% from interviewed parents and 67.5% from SMC cards. More than 23% of children experienced at least one side effect with the most common being vomiting (72%). The population’s overall impression of the program was good at 85%. The trends SMC coverage showed a sinusoidal fluctuation from 2015 to 2021, 2016 to 2019 and 2020 to 2021. Conclusion: The coverage rate of SMC was high thus the program is well implemented.

Does Primary and Secondary School Students'On-Campus Out-of-School-Hours Tutoring Reduce Private Tutoring Participation?—Based on China Family Panel Studies

This study analyzed the effect of primary and secondary school students'on-campus out-of-school-hours(OSH)tutoring participation on private tutoring participation using the two-level Bernoulli model based on the China Family Panel Studies(CFPS)data in 2018.The results revealed that students'on-campus OSH tutoring participation did not decrease the likelihood of their private tutoring participation,while low-achieving students or students from disadvantaged family socioeconomic status(SES)were more likely to continue to participate in private tutoring after receiving OSH tutoring.This may be due to the following:Firstly,on-campus OSH tutoring was less targeted and personalized before the implementation of the"double reduction"policy;secondly,private tutoring institutions conducted misleading marketing and offered private tutoring in the time for on-campus OSH tutoring;and thirdly,students with disadvantaged family SES had fewer opportunities to receive high-quality OSH tutoring.Therefore,it is suggested that concerted efforts be made to provide more targeted and personalized on-campus OSH tutoring and prohibit academic private tutoring institutions from entering campuses.Additionally,it is necessary to enrich the supply of OsH service resources for interest and quality development,optimize the allocation of on-campus OsH tutoring resources,and facilitate the balanced,quality-oriented development of OSH tutoring among different schoolsandregions.

Can Private Tutoring Improve Academic Performance?A Meta-Analysis Based on 21 Empirical Studies

The"double reduction"policy has shown initial success over the past three years.However,parents and off-campus training institutions continue to influence the policy implementation significantly.Aiming to investigate the correlation between private tutoring and academic performance,as well as identify key moderating variables,this study conducted a meta-analysis on 21 primary studies,encompassing 54 independent samples,79 effect sizes,and 242,601 participants.The findings revealed a low correlation between private tutoring and the academic performance of students.The impact of private tutoring on academic performance was insignificant after the application of the trim-and-fill method.Among the nine moderating variables analyzed,student gender,educational stage,family socioeconomic status(SES),region,tutoring subject,tutoring duration,and type of tutoring class did not significantly influence the effectiveness of private tutoring.The conclusions clarify the common one-sided perceptions people have about the role of private tutoring,offering new insights for education policymakers,researchers,teachers,parents,and students.
