School calendar: where time is gained and where it is lost

Listing structuring themes and anticipating small interventions throughout the months allows for flexible and consistent work

In the weeks leading up to the start of classes, the calendar usually reaches the teaching teams through information-dense institutional meetings. In many districts, especially in the state of São Paulo, these moments are led by professionals with different nomenclatures — CGP, CGPG, PC, PCA, COE — responsible for the pedagogical and organizational articulation of the school. In other regions of the country, the designations vary, but the scope of the function remains similar: interpreting guidelines, organizing collective planning, and mediating pedagogical work.

The environment usually reveals a careful attempt at hospitality. On a side table, freshly brewed coffee and small snacks announce scheduled breaks that promise to ease the morning or afternoon pace. Between presentations, professors take notes, record images of projections for later consultation, and talk in low voices as the meeting time progresses.

They are more or less predictable meetings where known content returns, many with new nomenclatures and renewed expectations. There is a collective effort to make the meeting lighter, even though the volume of guidelines anticipates future demands and responsibilities that do not always find, in the school structure, the necessary conditions for their full realization. In this scenario, the calendar appears as a formal guideline — still far from its potential as a living pedagogical instrument.

First of all, it is worth remembering that the calendar does not belong only to the school. It accompanies anyone who needs to organize goals over time. Those who intend to take a course, take care of their health, maintain a job, reserve time for family, or complete a project know that it is not enough to wish: it is necessary to look at the calendar of the month, mark commitments, divide priorities, and calculate possible intervals. This seemingly simple movement requires time and attention. Failing to plan the calendar means living at the mercy of improvisation.

In school, something similar happens. It is not enough to know that the student will remain for a few hours in the school environment — whether in partial, extended, or full-time education models. The question is not just how many hours are spent at the institution, but what is done with each minute of this time shared among students, teachers, and educational staff.

In her book “Policies of Full-Time Education in Brazil and Expansion of the School Day in the International Context”, published in 2024 by Editora Acadêmica, Professor Cláudia da Mota Darós Parente, from the Graduate Program in Education at Unesp, cites the importance of differentiating the expansion of time spent at school from what is understood as full education.

In the work, the author presents remarkable experiences that sought to reorganize the school and its times — and also its spaces. From the Children’s Parks project conceived by Mário de Andrade to the Escolas Parque in Salvador and Brasília by Anísio Teixeira, through the Experimental Classes, the Vocational Gymnasiums, the CIEPs, the Single Day for the Basic Cycle, and the Integral Attention Centers for Children (CAIC), a fertile seedbed of political and pedagogical initiatives aimed at expanding the school’s formative possibilities is revealed throughout the 20th century. Each temporal choice reveals, in this context, a conception of education and defines whether the lived time will be merely filled or truly formative.

Perhaps the calendar only truly comes into existence when it leaves the wall or the app and moves to the desk. The calendar, open before you, clearly exposing the commitments of the week, month, quarter, semester, and year, takes on another dimension when analyzed critically and in depth. A date marking an event immediately points to the preceding period, when the appropriate provisions will have to be taken, one by one, according to the methodology used by the professor, which will define the process and formative actions of the course. Four movements can help in the process of time organization:

1. Establish annual structuring axes

Instead of reacting to each campaign in isolation, the school can define two to four major axes aligned with its pedagogical project. Example: citizenship, cultural diversity, health, sustainability.

Campaigns and demands are now analyzed based on a simple question: do they dialogue with our priority axes? If yes, they are integrated into the path. If not, they assume a complementary character. The calendar ceases to react to demands and begins to guide the path.

2. Plan culminations in advance

Events do not need to interrupt the flow of pedagogical work. They should be a result of it. If there will be an action on indigenous culture in August, small interventions can occur since the first semester. The same can happen with black consciousness, inclusion, or traffic education. When the culmination arrives, it is a consequence of a process — not a rushed mobilization. Dates cease to be isolated peaks and become syntheses.

3. Create collective priority criteria

Not all external demands need to be central. By establishing clear criteria — alignment with the pedagogical project, formative impact, operational feasibility — management organizes decisions and reduces circumstantial pressures. Collective decision-making does not eliminate tensions, but avoids dispersion.

4. Integrate themes in cross-cutting projects

Fragmentation consumes time. Integration saves energy. An annual citizenship project can incorporate discussions on traffic, emotional health, and cultural diversity without multiplying disconnected events. The calendar then functions as a line of development, not a sequence of interruptions.

This meticulous examination distinguishes priorities, flexibilities, and inevitabilities. Although it may seem like extra work, it is precisely this that avoids a large part of future work. After all, the contemporary school calendar is not composed solely of teaching days dedicated to the distribution of curricular content, breaks, and holidays.

It carries a succession of relevant campaigns and social themes that span the entire year: White January, Blue April, Yellow May, Yellow September, Pink October, Blue November, among many other initiatives that broaden the discussion on health, inclusion, and citizenship.

Alongside these campaigns, civic dates and legal requirements persist, which call for the constant presence of cultural and historical themes in the curriculum, such as law 13.006/2014, which deals with the mandatory screening of national films in basic education, and law 14.988/2024, which establishes the realization of the Inter-school Cultural Week.

Listing structuring themes and anticipating small interventions throughout the months allows for flexible and consistent work, supported by a truly detailed calendar — not restricted to final dates, but attentive to processes that need to be gradually cultivated.

School management is responsible for guiding these initial organizational efforts, and the teacher for making them effective in the classroom. It is worth reinforcing: an initial effort that reduces frustrations and avoids extra work in the future.

Before demanding innovation, it may be necessary to go back to the simple calendar and ask: where is the time that is here? Where do our ideas really fit? Between meetings, campaigns, laws, and goals, the calendar continues to be the place where education gains substance or becomes mere formality. Reading the time carefully can be the first step for the school year to cease being a sequence of urgencies and truly become a formative journey.

At the end of the initial pedagogical orientation meeting, when the coffee cools and the notebooks close, the same silent question that opened the encounter remains: how to transform lived time into experience that makes sense? One possible answer is to remember that no training is complete if it leaves aside what truly matters — the integral human being who needs to emerge from it.

Determinants of supermarket location in São Paulo

A study investigated the determining factors for supermarket location in the state of São Paulo, with the objective of investigating the factors that explain the presence and expansion of these establishments, considering socioeconomic, demographic, and market dimensions. Data from the 2010 and 2022 Demographic Censuses of IBGE and information from the National Registry of Legal Entities of the Federal Revenue of Brazil were used to build a georeferenced database. A Random Forest classification model was applied, adjusted by grid search with cross-validation, prioritizing the recall-macro metric due to the imbalance of the dependent variable, which represented the presence or absence of supermarkets within a 50-meter buffer. The results indicated that supermarket location is strongly associated with demographic, income, and population characteristics in the surrounding area. The analysis of variable importance showed that sociodemographic factors, such as elderly literacy, household income, and the presence of other food establishments, exerted significant influence, especially in the immediate vicinity. The findings reinforced the hypothesis that the spatial distribution of supermarkets is not random, being conditioned by socioeconomic characteristics and the commercial structure of the territory, offering subsidies for business decisions and urban planning.

Anti-Racist Education: Inclusive Educational Practices and Social Development

Antiracist education, understood as a structuring axis of inclusive education and social development, was investigated in the Brazilian context. The study aimed to identify and analyze, based on legal documents and teachers’ perceptions, educational practices capable of promoting antiracism in school and society, and how the implementation of Laws nº 10.639/03 and nº 11.645/08 contributed to social justice. A qualitative and documentary approach was adopted, with analysis of educational legislation, curricular guidelines, institutional reports, and academic literature. Complementarily, a semi-structured questionnaire was applied to 295 Basic Education teachers. The data were evaluated quantitatively and qualitatively, through thematic content analysis, and validated with bibliographic studies. The results revealed a paradox: despite a robust legal framework, the implementation of antiracist policies proved fragile and sporadic, with a lack of teacher training, adequate teaching materials, and monitoring. Significant educational inequalities between white and black students were found to persist, and most teachers acknowledged the occurrence of racism in schools, but without clear institutional protocols. Neuroscientific analysis showed that racism negatively impacts students’ cognitive and emotional development. It was concluded that antiracist education is central to quality education, requiring political commitment, public investment, and intersectoral articulation. The integration of Neuroscience in teacher training and the production of qualified materials are crucial to strengthen the school’s role in building a more just and inclusive society.

Paths of Inclusion: Perceptions of Parents and Teachers on the Schooling of Students with Dual Exceptionality in the Brazilian Context

Dual Exceptionality, characterized by the coexistence of High Abilities/Giftedness and neurodevelopmental disorders, represents a complex phenomenon that challenges traditional identification and schooling models. The study aimed to understand the perceptions of parents or guardians, teachers, and other education professionals regarding the schooling of students with Dual Exceptionality in the Brazilian context, investigating challenges, pedagogical strategies, and possibilities for inclusion based on equity. The research adopted a qualitative, exploratory, and descriptive approach, and collected data through an online, voluntary, and anonymous questionnaire answered by 25 participants. Discursive data were analyzed using thematic content analysis. The results indicated that knowledge about the topic is often built from personal and professional experiences, revealing gaps in systematic training. Difficulties were identified in identifying these students, in teacher training, and in implementing individualized educational plans, pedagogical flexibility, and curriculum enrichment. Socio-emotional repercussions, such as frustration and low self-esteem, were reported. However, some schools demonstrated inclusive practices based on equity, articulating specific needs and potentialities. Although the results do not allow for generalizations, they highlighted the need to strengthen professional training and the articulation between school, family, and specialized services. It was concluded that the inclusion of students with Dual Exceptionality requires practices that simultaneously recognize their difficulties and potentialities, ensuring equitable conditions for participation, learning, and development.

Data Transformation into Strategy: Applied Research for Ecotourism Operation Optimization

The growing demand in ecotourism in Minas Gerais has driven the search for business intelligence to transform customer data into strategic information. The study aimed to structure a data science pipeline to collect, segment, and classify the customer base of an ecotourism operation, in order to optimize marketing actions and anticipate market movements. An exploratory, quali-quantitative research was conducted through a case study. 2,777 transactional records from an ecotourism company, referring to January 2024 to December 2025, were used. The methodological process involved automated data collection (Google Sheets API), processing and enrichment (ETL), validation, and creation of RFM (Recency, Frequency, and Monetary Value) attributes. Dimensionality reduction via PCA and K-Means clustering was applied, with the number of clusters defined by the Elbow method and Silhouette Score. The results were validated with DBSCAN and K-Medoids. The results revealed the identification of three behavioral customer segments: “Loyal”, “Low Value”, and “Potential”. The “Loyal” segment represented the highest accumulated economic value, while the “Potential” segment stood out for its high average ticket and potential for conversion into recurrence. The integration of data analysis techniques proved to be a robust and replicable method for generating intelligence in ecotourism. It was concluded that the structured data science pipeline enabled the behavioral segmentation of the customer base, the statistical validation of the groups, and the creation of a predictive system for new buyers, providing subsidies for data-driven strategic decisions and future analyses.

Classification of defaulting customers using supervised machine learning techniques

The risk of default in credit operations demanded analytical approaches to anticipate losses. This study comparatively evaluated the performance of supervised machine learning models in classifying defaulting customers in credit card operations. The public dataset “Default of Credit Card Clients” from the University of California Irvine was used, with 30,000 observations and class imbalance. The algorithms Logistic Regression, Random Forest, and Extreme Gradient Boosting were employed. The imbalance was addressed by assigning weights to the classes, and model optimization occurred with the RandomizedSearchCV method, prioritizing sensitivity. Cross-validation results indicated that the Extreme Gradient Boosting model showed a higher capacity for identifying the defaulting class and better discriminatory performance, followed by Random Forest and Logistic Regression, with a sensitivity of 0.8250 and an AUC-ROC of 0.7844 for XGBoost. Interpretability analysis, conducted by the Shapley Additive Explanations (SHAP) technique, highlighted the predominance of variables associated with payment behavior, especially the history of delays. It was concluded that tree-based models, particularly boosting techniques, proved to be more suitable for capturing complex patterns in the data, configuring themselves as consistent alternatives for credit risk management.

Sentiment Analysis on Brazilian Banks on Twitter/X: Comparison between Traditional and Digital Institutions

A study analyzed public perception of Brazilian financial institutions on the Twitter/X platform, highlighting the importance of sentiment monitoring on social networks for understanding reputation and customer experience in the banking sector. The objective was to compare user perception of the image and reputation of traditional and digital banks, based on the sentiment patterns identified in the analyzed manifestations, seeking to identify structural differences between these groups. The methodology was based on the analysis of 1,096 tweets collected between November 2022 and June 2023. Two complementary sentiment analysis approaches were used, the sum and the average of labels, to capture the majority sentiment and nuances of perception. Additionally, the Market Profile Model, with indicators of emotional reputation, reputational risk, neutrality, and polarization, and the Banking Clustering Model, which allowed grouping institutions according to perception patterns, were developed. The results indicated a predominance of neutral and negative sentiments, a higher volume of interactions in digital banks, and structural differences in the emotional intensity of perceptions, with greater stability in digital banks and greater polarization in traditional ones. It was concluded that the combination of analytical and statistical techniques contributed to an in-depth understanding of institutional image in the digital environment, demonstrating the importance of data-driven reputation management strategies.

Optimization of annual budget planning through project management methodologies

The Annual Budget Planning (POA) is a crucial process for translating organizational strategy into operational and financial goals, but it frequently faces deadline pressures, interdepartmental dependencies, and the repetition of habitual expenses. The study aimed to analyze how the combined application of project management practices and Zero-Based Budgeting (OBZ) can optimize the POA. To this end, a case study was developed in the Brazilian operation of a publicly traded company in the beverage sector, using documentary research of its 2023 results report and an anonymous questionnaire applied to 47 respondents. Documentary analysis indicated growth in net revenue, expansion of gross profit and adjusted EBITDA, and contained advancement of selling, general, and administrative expenses, suggesting cost discipline and operational leverage. The complementary survey revealed a high perception of cascading effect on the schedule, strong support for defining cost package owners, and a preference for technical justification of expenses, in addition to demand for controlled flexibility after the baseline definition. It was concluded that structuring the POA as a project, associated with the rigor of OBZ, increased the process predictability, reinforced accountability for expenses, and broadened the coherence between budgetary execution and economic-financial performance.
