- Tesis Título Profesional Acceso EmbargadoResolución de problemas matemáticos en estudiantes de segundo grado de secundaria en instituciones educativas del distrito de San Juan Bautista 2024(Universidad Nacional de la Amazonía Peruana, 2026) Dosantos Huansi, Emil; Rengifo Ruiz, Roger ErnestoThe main objective of this research was to examine the achievement levels of reasoning skills applied to mathematical problem-solving. The study involved second-grade secondary school students from educational institutions in the San Juan Bautista district during the 2024 academic year. Methodologically, the work followed a quantitative approach, utilizing a descriptive, univariate, and cross sectional design. From a total population of 1,709 students, a representative sample of 314 participants was selected through a stratified random sampling technique. Data collection was carried out using a performance test consisting of 31 items, organized into the dimensions of understanding, planning, execution, and verification. This instrument was validated by expert judgment and demonstrated a high internal consistency (α = 0.811). The findings revealed that a majority of the students (66.56%) were at the "Beginning" level, while 29.30% were "In progress." Only a minimal fraction (4.14%) reached the "Expected achievement" level, with no students recorded at the "Outstanding achievement" level. This trend of low performance was consistent across all evaluated dimensions, reflecting significant limitations in mathematical reasoning capabilities. Consequently, it is concluded that the observed achievement levels are insufficient, highlighting the urgent need to strengthen pedagogical strategies focused on developing reasoning and reading comprehension within the educational context of the San Juan Bautista district.
- Tesis Título Profesional Acceso EmbargadoEstrategias de lectura y el pensamiento creativo en niños de la Institución Educativa Inicial N°728, Caballococha 2024(Universidad Nacional de la Amazonía Peruana, 2026) Maricahua Garcia, Marivel; Oyarse Sangama, Lady DianeThe main objective of this research was to determine the degree of relationship between reading strategies and creative thinking in children at Initial Education Institution No. 728 in Caballococha, 2024. The study was conducted using a quantitative, basic approach with a non-experimental, correlational, and cross sectional design. The population consisted of 118 preschool children, who were assessed using a validated and reliable observation guide to evaluate both variables. The results obtained using Spearman's rank correlation coefficient showed a significant and positive relationship between reading strategies and creative thinking in the students of the aforementioned institution. The calculated coefficient was Rho = 0.676, indicating a moderate-to-high and directly proportional correlation. Furthermore, the two-tailed significance value (Sig. = 0.05) was within the accepted critical threshold, allowing the null hypothesis to be rejected and the general hypothesis to be accepted. Therefore, it is concluded that a significant relationship exists between both variables, as demonstrated by the statistical analysis.
- Tesis Título Profesional Acceso EmbargadoInteligencia emocional y autorregulación del aprendizaje en estudiantes de educación primaria de la Institución Educativa Religiosa Buen Retiro N° 60565 Alfredo Vargas Guerra, Nauta 2025(Universidad Nacional de la Amazonía Peruana, 2026) Guevara Pinedo, Rubi del Rocio; Panduro Urrelo, Harvey EnriqueThis study determined the relationship between emotional intelligence and self regulated learning in primary school students at the Religious Educational Institution Buen Retiro N° 60565 Alfredo Vargas Guerra in Nauta. A basic, non-experimental, cross-sectional, quantitative-correlational investigation was conducted. The population consisted of 130 students, with a sample of 98 participants selected through proportional stratified sampling. Two Likert-type questionnaires were applied. Statistical analysis revealed a positive and very strong correlation between both variables (Rho=0.957; p<0.001). By dimensions, the coefficients were: intrapersonal (Rho=0.876), interpersonal (Rho=0.825), adaptability (Rho=0.943), stress management (Rho=0.889), and general mood (Rho=0.920), all with statistical significance (p<0.001). It was concluded that there is a direct and very strong relationship between emotional intelligence and self-regulated learning in the studied context.
- Tesis Título Profesional Acceso EmbargadoMateriales educativos y rendimiento escolar en niños de cinco años de la Institución Educativa Inicial N° 162 Los Honguitos, Iquitos 2025(Universidad Nacional de la Amazonía Peruana, 2026) Ahuanari Sanchez, Ericka Briggit; Vásquez Pinedo, Gladys MarleneThe present research analyzed the relationship between the use of educational materials and academic performance in 5-year-old children from the Initial Educational Institution No. 162 “Los Honguitos,” Iquitos. Using a quantitative approach and a non-experimental design, a sample of 147 students was evaluated. The descriptive results revealed that 92.5% rated the use of materials as “good,” and 98.6% showed “satisfactory” academic performance. The results of the Spearman correlation analysis showed that there is no statistically significant relationship between the use of educational materials and academic performance among the evaluated students (Rho = 0.033, p = 0.688 > 0.05). The obtained coefficient reflects a very weak negative correlation, indicating that both variables behave independently in the studied sample. Therefore, it is concluded that the level of use of educational materials is not significantly associated with the academic performance of the evaluated students.
- Tesis Título Profesional Acceso EmbargadoObtención de bioetanol por hidrólisis ácida de la cáscara de cacao (Theobroma cacao L.) Iquitos 2025(Universidad Nacional de la Amazonía Peruana, 2025) Silva Rondón, Benjamin Alexander; Velasquez Parco, Jheraldin Milagros; Suárez Rumiche, Jorge Antonio; Gómez Tuesta, Luis; Chang Gomez, Mario AndrewThis research evaluated the feasibility of obtaining bioethanol from cocoa pod husks (Theobroma cacao L.) through acid hydrolysis and alcoholic fermentation as a renewable energy alternative for the Iquitos region, Peru. A 3² factorial experimental design was employed with three levels of sulfuric acid concentration (2%, 4%, and 6%) and three hydrolysis times (30, 60, and 90 minutes) at a constant temperature of 120°C, with three replicates per treatment. Acid hydrolysis produced reducing sugar concentrations ranging from 18.5 g/L to 42.3 g/L, with the treatment using 6% sulfuric acid for 90 minutes generating the highest concentration. Alcoholic fermentation with Saccharomyces cerevisiae was performed at 30°C for 120 hours, achieving bioethanol concentrations between 3.2% and 8.7% v/v. The maximum bioethanol yield was 8.7% v/v (68.4 g/L) with the treatment of 6% acid and 90 minutes of hydrolysis, equivalent to 0.087 g of ethanol per gram of dry husk. Statistical analysis through ANOVA showed significant differences (p <0.05) between treatments, confirming that both acid concentration and hydrolysis time significantly influence bioethanol yield. It is concluded that cocoa pod husks are a viable raw material for second generation bioethanol production, contributing to the utilization of agroindustrial waste and the development of renewable energy in the Peruvian Amazon region.
