Learning Scenario to Promote Comprehension of the Meaning of Subtraction

The integration of virtual manipulatives in classroom practices facilitates student learning processes. For this, the teacher must understand how to support students in establishing mathematical connections between the manipulation and their interpretations of the representations. We present a learning scenario that integrates the use of virtual manipulatives in mathematical modelling tasks. It was designed and implemented during initial teacher training, with the aim of helping a group of first-year elementary school students to overcome difficulties identified in their comprehension of the meaning of subtraction. The research, following the principles of design-based research, included three distinct moments: an individual written pre-test, an intervention phase with six micro-cycles, and an individual written post-test. The analysis of the collected data—audio, screen recordings, and written productions—allowed us to identify the most influential structural characteristics of the learning scenario: mathematical communication, collaborative learning, self-regulation, and co-regulation of learning. Our results suggest that differentiated instruction, minimal guidance, and scaffolding played an important role in the support provided by the pre-service teacher to students in the mathematical modelling activities that integrated virtual manipulatives.
Histogram Based Optimized Reversible Steganographic Scheme

A novel prediction-based Reversible Steganographic scheme based on image inpainting can be optimized by choosing the reference pixels using optimization technique. Partial differential equations based on image inpainting are introduced to generate a prediction image, from the reference image that has similar structural and geometric information as the cover image. Then the histogram of the prediction error is shifted to embed the secret bits reversibly using two selected sets of peak points and zero points. From the stego image, the cover image can be restored losslessly after extracting the embedded bits correctly. Since the same reference pixels can be exploited in the extraction procedure, the embedded secret bits can be extracted. Through optimization of reference pixels selection and the inpainting predictor, the prediction accuracy is high, and more embeddable pixels are acquired with greater embedding rate and better visual quality, and reduced time required for the stego00 image generation.
Analysis on Productivity, Performance and Upward Mobility of Faculty Members

This research's main objective was to decide if the mobility of faculty indeed increases the efficiency and productivity of faculty in terms of teaching, research, and extension. A descriptive research design was implemented in the analysis. Faculty members with a professorial rank based on the National Budget Circular Period assessment were regarded as the study respondents. In terms of main outcome areas, the table of indicators per dimension was used in State Universities and Colleges' leveling instrument. There is a very strong inter-rater agreement with the collected data using Cohen's Kappa Index for face validity. Using Lawshe's method and an internal consistency measure of 0.84 using Cronbach Alpha Coefficient, a content validity ratio is calculated for each object. The Pearson product-moment correlation coefficient was used to calculate the strength of a linear relationship between two variables, following the assumptions underlying its use. The researcher uses a significance level denoted by alpha set at 0.05 statistically relevant to assess the level of significance. To determine the shift in faculty efficiency and productivity over time, the rate of change was used. As the rank of the faculty increases, the corresponding salary rise was also observed. Regarding upward mobility over time, faculty members' success level is increasingly growing in instructional study and extension services. In terms of instructional research and extension resources about upward mobility over time, faculty members' degree of productivity is lower than the faculty's performance.

Privacy Requirements Specification in Agile Software Development : RE’2021 Tutorial

Privacy has become a concern in Agile Software Development (ASD), either to satisfy users' needs or to comply with privacy laws. However, recent studies have shown that ASD approaches still neglect non-functional requirements (NFRs), as is the privacy case. This concern and new data protection laws that came into force recently led companies to face the challenges to understand the laws and to comply with them. In addition, research has shown that many developers do not have sufficient knowledge about how to develop privacy-sensitive software. Motivated by this scenario, this tutorial aims to draw attention to the need to understand privacy from the beginning of the software development lifecycle. Initially, we will present an overview of privacy, as well as several privacy principles. Later, we will show the main data protection laws (In-depth detailing of the General Data Protection Regulation - GDPR). Then, we will discuss how to read and evaluate privacy policies. Finally, we will present an approach for specifying privacy requirements in ASD called Privacy Criteria Method (PCM). At the end of the tutorial, participants will be able to have a critical and technical view of privacy when performing the requirements specification activity.

A COMPARISON OF M-ESTIMATION AND S-ESTIMATION ON THE FACTORS AFFECTING IR DHF IN EAST JAVA IN 2017

ABSTRACTRobust regression on M estimation and S estimation is the Ordinary Least Square (OLS) regression on the data outlier. East Java is one of the provinces in Indonesia with a high case fatalitiy rate (1.34%). The raising of Dengue Haemoragic Fever (DHF) in East Java has been influenced by climate, population density, human behavior, and environmental sanitation. This study aimed to compare robust regression research by using M estimation and S estimation on the factors that affect IR DHF. This was done to get the best model regression on the data outlier based on the biggest R2 adjusted and the smallest MSE. This study utitlized observational research with a non-reactive research design using secondary data. The independent variable consisted of population density, healthy behavior, healthy living environment house, and precipitation in East Java in 2017. The dependent variable was incident rate of DHF in 2017. The population included 38 regencies in East Java, while the sample was 35 regencies/cities selected using simple random sampling. The analysis used robust regression on M estimation and S estimation weighting by Tukey’s Bisquare. Robust regression on S estimation was found to be the best robust regression on data outlier with R2 adjusted (0.996) and MSE (0.229). Robust regression on S estimation was = 54.826 + 0.011 (population density) – 0.136 (% healthy behavior) - 0,404 (% healthy house ) - 0,005 (precipitation).Some factors that affect IR DHF can be the main focus for the prevention and control of DHF for the government and society.

A Learning Objective Controllable Sphere-Based Method for Balanced and Imbalanced Data Classification

Imbalanced data classification is one of the most important tasks in the field of machine learning because abnormality, which is usually of our interest, appears less frequently than normality in real-world systems. Learning classifiers from imbalanced data can be troublesome due to no absolute standard as to how much imbalance can be said to be imbalanced or balanced. To address this issue, this research proposes a new sphere-based classification method named LOCS (learning objective controllable sphere-based classifier), which is designed to maximize AUC (area under ROC curve). The AUC learning objective was adopted from the fact that it approximates the accuracy as class distribution becomes balanced. Therefore, the proposed method properly performs a classification task for both imbalanced and balanced data. It constructs a classification model by a single training, whereas existing cost-sensitive learning and resampling methods usually attempt different parameter settings. In addition, the learning objective can be easily modified within LOCS for each of application domains by setting different importance levels for positive and negative classes, respectively. Numerical experiments based on 25 real datasets with several investigational settings showed the effectiveness and the intended strengths of the proposed method.

Warrant Generation through Deep Learning

The warrant element of the Toulmin model is critical for fact-checking and assessing the strength of an argument. As implicit information, warrants justify the arguments and explain why the evidence supports the claim. Despite the critical role warrants play in facilitating argument comprehension, the fact that most works aim to select the best warrant from existing structured data and labelled data is scarce presents a fact-checking challenge, particularly when the evidence is insufficient, or the conclusion is not inferred or generated well based on the evidence. Additionally, deep learning methods for false information detection face a significant bottleneck due to their training requirement of a large amount of labelled data. Manually annotating data, on the other hand, is a time-consuming and laborious process. Thus, we examine the extent to which warrants can be retrieved or reconfigured using unstructured data obtained from their premises.
REFLECTION AS THE BASIS OF THE PRIMARY PUPILS’ LEARNING ACTIVITY

The article deals with the problems of reflection in the organization of primary schoolchildren’s educational process, characterizes the functions of reflection, describes the classification of reflection types. The authors argue that a teacher should be able to apply various methods and techniques of reflection when planning a lesson and include it in the pedagogical process at different stages: when updating knowledge and strengthening learning, repeating and summing up educational material. The ability of pupils to reflect and to assess their educational activities adequately will depend on a competent pedagogical approach, the correct choice of pedagogical methods, techniques and means.
Summarization of Hindi News Editorial with Sentiment Determination

Text summarization is a natural language processing application that is being researched extensively and applied further to reduce the processing time for various long-winded text-based activities. However, as NLP is still in its budding phase, the work is relatively limited to the English language, leaving regional languages rather untouched despite having an incredible following of speakers. Such is also the case with the Hindi language. In this paper, we propose to come up with an effective method of summarisation news articles in the Hindi language. Like the English variant of this application, we wish to emphasize on the important sections of a Hindi news report and summarize it within 60 to 80 words. The summarization technique will try to identify the theme of the news, named entities and numbers, title terms, etc., for constructing a keyword table. This will be further compared against a knowledge base with weighted keywords for ranking the important sentences in the relevant order and finally picking out the sentence most needed for the summary. Our goal for summarizing the Hindi news articles specifically roots from the dilemma that despite these articles being a rich source of opinionated information about various topics, they are often ignored by the readers because of their long-winded nature that makes the useful information lost in the sea of words decorated by winded introductions and linguistic ornaments like idioms. Hence, this system should enable in an effective means of summary for finding useful information along with pruning all such irrelevant details.
