Exploring university mathematics professors’ perceptions and use of GenAI: a conceptual fields approach

2025-10-21T21:11:13+00:00

Generative Artificial Intelligence (GenAI) is rapidly transforming higher education, challenging traditional pedagogical norms, and prompting a re-evaluation of teaching and learning practices. This study analyzes the operational invariants guiding university mathematics professors' action schemes when interacting with GenAI, using the Theory of Conceptual Fields (TCF) as a theoretical framework. Semi-structured interviews were conducted with ten active university mathematics professors, focusing on the eight dimensions of Technological Pedagogical Content Knowledge (TPACK). Transcriptions were analyzed to infer enacted theorems (ETs), classified into eight thematic categories: general functionality, prompt construction, knowledge validation, academic applications, ethics and regulation, relationship with teaching and learning, teacher knowledge and use, and limitations and risks. Results revealed a predominantly pragmatic usage scheme, with GenAI perceived as a search engine, process optimizer, and code generator. However, contradictory ETs indicate that the conceptual field is still under construction. Teachers primarily use GenAI for text editing, content generation, and idea organization, but its direct classroom use remains limited. Epistemological ambivalence exists regarding Gen's authority, with concerns about errors. Ethical and regulatory issues are not yet central. Findings highlight the need for critical, reflective, and context-sensitive appropriation of GenAI in university mathematics education, supported by professional development and institutional policy.

Analysis of Professional Training Actions and Performance of Public Servants in Mozambique, Zambezi University Case (2018-2022)

2025-10-21T20:28:21+00:00

The research aims to analyze the professional training actions and performance of Public Servants in Mozambique, such as the Zambeze University (UniZambeze), following the Global Public Sector Reform Strategy, launched by the Government in June 2001. This is guidance for all public institutions to improve the quality of services and the State's responses to society. The research question seeks to assess how professional training actions for employees of UniZambeze's Administrative Technical Body (CTA) contribute to improving their professional performance. Regarding technical procedures, it is exploratory research, of an applied nature and a qualitative approach, as it aims to provide an overview of the impact of professional training actions on the performance of public servants and the subjects of the investigation are the CTA of UniZambeze. It was found that employees annually undergo professional training courses and courses leading to a degree, to respond to new demands, challenges, globalization, behavioral changes, reinforcement of working conditions, improvement of employee qualifications and performance. Therefore, the data indicated that the professional training of CTA employees contributes to their professional development and improved performance.

Epiisopiloturin–Hydroxypropyl-β-Cyclodextrin inclusion complexes: preparation, characterization, and application in neglected diseases

2025-10-07T21:34:03+00:00

Context: Pilocarpus microphyllus (Jaborandi) is widely used for extracting pilocarpine, generating biomass rich in secondary metabolites. Among these, epiisopiloturin (EPI) exhibits potential against neglected diseases, in addition to anti-inflammatory and antinociceptive effects. However, its poor aqueous solubility limits its pharmaceutical application. Objective: To enhance the solubility of EPI by forming an inclusion complex with hydroxypropyl-β-cyclodextrin (HPβCD) using the freeze-drying technique. Methods: A phase solubility study was conducted to determine the stability constant and stoichiometry. The inclusion complex was prepared via lyophilization and characterized by Differential Scanning Calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and in vitro dissolution testing. Results: Characterization confirmed the formation of the EPI:HPβCD complex, indicating strong interactions between components. The DSC thermogram showed the disappearance of the EPI melting peak, supported by FTIR results, suggesting successful complexation. XRD patterns revealed an amorphous structure. In vitro dissolution demonstrated a marked increase in solubility: 100% of the complexed EPI dissolved within 5 minutes, compared to only 19% of the free compound. Conclusion: Complexation with HPβCD significantly improved the solubility of EPI, reinforcing its potential for development into an innovative pharmaceutical formulation for the treatment of neglected diseases.

“The mil aulas tool in moodle for meaningful learning in entrepreneurship and management: A case study in ecuadorian high schools”

2025-10-03T21:45:43+00:00

The rapid and progressive advancement of computerized technology has compelled educational processes to migrate toward learning environments that require the use of digital platforms and tools. These environments foster the exploration and experimentation of contextualized didactic designs, with implications for the development of skills that transcend purely theoretical knowledge. This article aims to analyze the applicability of pedagogical methodologies for implementing collaborative practices among third-year students of the Unified General Baccalaureate (BGU) in Ecuador, specifically within the curricular unit of Entrepreneurship and Management, mediated by the Mil Aulas tool in Moodle. The theoretical framework is grounded in the approaches of Ausubel, 1983 and Siemens, 2004, from a socioconstructivist perspective. Methodologically, a non-experimental, cross-sectional design was adopted within a projective research approach, using a census sample of 90 students from the Tonchigüe High School in Atacames, Ecuador. Based on the average performance across the four groups, the findings indicate that mean scores increased by 90%, rising from 4.88 in the pre-test to 9.28 in the post-test. This result demonstrates a significant improvement in students’ academic performance, strengthening their knowledge of markets and advertising, and contributing to meaningful learning.

Sustainability analysis of the tourism system in El Capulín community, Monarch Butterfly Biosphere Reserve

2025-08-19T14:57:56+00:00

The construction of indicators allows us to detect critical points of the analyzed system, to detect causes and provide solutions. In the tourism area, the indicators are limited, although their application helps to quantify the functioning of the destination and generate strategies that benefit those involved. The objective of this research was to carry out an analysis of the sustainability of producers in El Capulín community using indicators in dimensions; economic, social and environmental with the purpose of generating a baseline in the sustainable area, which serves for rural development, supported under the Framework for the Evaluation of Natural Resource Management Systems incorporating Sustainability Indicators. A structured survey was designed, referring to tourist activity, applied with intentional sampling to 63 ejidatarios. The statistical analysis generated six indicators in the economic dimension, six environmental and ten social, the evaluation of the system allowed us to know that the PSTP group has 65.03% sustainability, while the PSTM group has 85.25%, the interaction in the system showed that Tourism is not an economic activity that provides a good quality of life to those interested, therefore, increase your knowledge as a strategy to improve your performance and skills.
