  • Back to the Face-to-Face classroom: instructors' perceptions on students' performance

    Dreifuss-Serrano, Cristina; Schreier-Barreto, Christopher (Institute of Electrical and Electronics Engineers Inc., 2022-01-01)
    After almost two years of exclusive online formats for higher education, students recently returned to campus and face-to-face activities. Even though this was much awaited, the perceived results from the instructors' point of view seem to show that students are not as prepared as they were in face-to-face environments before the pandemic. Using a survey, we obtain information on the perceptions of studio instructors, in several universities in Lima, Peru. Asking questions about students' performances in the specific parts of the process, and about the instructors' perceptions of their own attitudes and methods, we established which specific aspects seemed to have been most affected by the changes in education format. Most instructors agree that students' performance has worsened after going back to face-to-face classrooms, when compared to their teaching before the pandemic. We take this opportunity to reflect on the transitions from physical to virtual and back to physical environments, and the opportunities they present for reflection and evaluation on our teaching approaches.

  • SDGs for the assessment of voluntourism learning experiences

    Dreifuss-Serrano, Cristina; Herrera, Pablo C. (Institute of Electrical and Electronics Engineers Inc., 2022-01-01)
    Problem Based Learning (PBL) strategies aim to close the gap between theoretical knowledge and real-world situations, especially in higher education. Studying six experiences of voluntourism (volunteer tourism) carried out in Lima, Peru, and the previously established tasks and stages of such projects, we propose a way of approaching Sustainable Development Goals to real-life pedagogical experiences. SDGs are used not only as objectives, but also as assessment tools for both projects and teaching opportunities, while becoming real part of the curricula.

  • Wood wide web design. A computational model to adapt the cities design with mycorrhizal networks

    Reategui, Jose L. (Institute of Electrical and Electronics Engineers Inc., 2022-01-01)
    The design and construction of architectural objects and cities design seeks to relate to their environment through local data collection systems that understand the environment as a static system related with bio dynamics where trees represent a community with low interaction. It was demonstrated that almost all forests in the world are communities with trees in constant communication through mycorrhiza fungi, forming an essential part of the forest's livelihood, its resilience, and ability to adapt to human intervention events. This research proposes a computational model designed to incorporate vectors into a parametric design system with the aim of showing nutrient flows based in the link between trees and mycorrhiza fungi in project intervention areas and existing construction, connecting the cities design proposals and building and cities performance analysis with the objectives of contribute to conserving, protecting, and restoring life on earth in a post-carbon era from architecture, urban design, and landscaping. These vectors are the result of the analysis of orchid health and the use satellite images in different bands, all this process is supported by machine learning, Internet of Things, edge and cloud computing technologies.

  • Promoting early childhood development through built environment transformations: lessons from the safe route project in Lima, Peru

    Cepero-Saravia, Jose; Dreifuss-Serrano, Cristina; Ortigoza, Ana (Routledge, 2023-01-01)
    Early childhood development is crucial for children’s growth and long-term outcomes. In Peru, the government has made investments in education and health, aiming to support child development programs. However, more work is needed in other areas to ensure all children can thrive. This paper explores the potential of interventions in the built environment as a relatively unexplored area that could benefit child’s development. We present the implementation of the ‘Safe Route to the “Mercedarias” daycare’ project as a successful experience for promoting child-friendly cities. The project involved collaboration among mid-level officers and frontline workers within a large municipality’s organizational structure. The strategies we used allowed us to build a working group willing to collaborate on further projects. The process was successful without requiring additional expenses beyond regular costs. Officers that had never been involved before felt engaged with the initiative while testimonies from caregivers indicated positive outputs. The case study could serve as an example to other cities of a successful model for promoting early childhood development in cities by engaging stakeholders at all levels in the identification of challenges faced by young children and caregivers while underscoring the importance of investing in urban environment interventions for improving children’s growth.

  • Visual Programming for Teaching Geometry in Architectural Education

    Herrera, Pablo C.; Hurtado, Michael; Arteaga-Juárez, Pedro (Springer Science and Business Media Deutschland GmbH, 2023-01-01)
    Mathematicians and computational designers from a School of Architecture, explore visual programming in the environment of a design software with exercises of a basic mathematics course to overcome the limitations of hand drawing and computerized representation of geometry. We link the learning of geometry, which was associated with abstract aspects of mathematics, with the possibilities of solving design problems in the same environment that students use to design with technologies. Visual programming allowed to create and reuse formulas that modeled variations of different exercises, preparing the model for visualization and digital fabrication with 3D printing and laser cutting. This research promotes a learning experience using algorithms and personalized computer graphics throughout design learning and to value the use of mathematics to explore geometric possibilities in design problems.

  • Transformation by appropriation of the free planned spaces in the Neighborhood Unit No 3

    Campos-García Calderón, Inés Magdalena; Olivera Mendoza, Doraliza (Universidad de Chile, Instituto de la Vivienda, 2022-05-01)
    The Neighborhood Unit No 3 (UV3) was an approach to social housing based on the theory of the Neighborhood-Unit and the Satellite City, where Planned Open Spaces (POS) were relevant for the health and community development of the population. These were occupied and their physical-architectural characteristics were transformed. The objective of this research was to identify the transformation by appropriation of POS in UV3. Using a qualitative approach, a graphical comparative analysis of the original approach versus the current situation, documentary analysis and field observation were carried out. Changes were found identified based on the placement of material elements to delimit and subdivide spaces, and the incorporation of these to the residential space, changes in the use from collective green area to the individual space of the adjoining house, and the placement of symbolic elements of recognition. All of which result in different types of appropriation: according to the agent, the nature, and the consequences. It is concluded that the transformation of the POS from the original approach has been possible due to the disproportionate size of their areas, and is the result of different forms of appropriation that have generated an informal urban profile.

  • Fab Lab-based learning: an environment to promote Women and Leadership in Engineering Education

    Herrera, Pablo C.; Dreifuss-Serrano, Cristina; Valenzuela-Zubiaur, MacArena; Caycho, Vaneza (IEEE Computer Society, 2022-01-01)
    The gender gap remains one of the outstanding problems in engineering education. However, there are global learning communities with more than a decade that show sustainable statistics for learning and leadership in STEM environments. This research analyzes the participation of women in the Fab Lab-based learning environment of the Fab Academy in the geography of IEEE Region 8 and the 28 countries that graduated 721 students between 2009 and 2021. We analyze the 31.21% of women graduated and the specificity of its scope in each sub region, from the context of the learning environment to those who management a Fab Lab. Demonstrating a line that takes up learned knowledge, orienting them to learning and leadership.

  • Going out for a walk: Empathizing with streets through their façades in Lima

    Ramírez, Miguel Córdova (Universidad de Chile, Instituto de la Vivienda, 2022-01-01)
    Walking down a street is not the same as going out for a walk. One of the differences is that by going out for a walk it is possible to empathize with the city façades. Through a qualitative and comparative analysis of the perceptions and urban imaginaries of young adults, we propose to analyze how they understand walking through the different streets of the Lima neighborhoods of Lince, Jesús María, and Santa Beatriz, which are experiencing physical changes in their streets due to the expansion of the real estate market. It was revealed that the disposition to empathize with façades was related to an idea of life that was used as a differentiating factor, and which included attributes of location, visibility, variety, sense of community, and historicization. Therefore, when there was greater disposition to empathize with the streets, walking acquired a new character and people did go out for a walk.

  • Effects of waste glass powder as pozzolanic cement supplementary material for structural elements

    Del Pino, Sebastian; Milachay, Daniela; Rodriguez, José; Eyzaguirre, Carlos (Trans Tech Publications Ltd, 2022-01-01)
    The ever-growing global production of glass generates high waste percentages, the vast majority of which does not get recycled hence increasing the concern on its environmental impact. Studies on the pozzolanic properties of glass powder emerged as a solution to the abundance of waste glass powder available and its insufficient recycling. The aim of this study is to investigate the influence 10%,15% and 20% of waste soda-lime glass powder as partial cement replacement; fresh concrete tests were carried out, as well as compression strength tests at 28 days on grade 280 kg/cm2 concrete produced with pozzolanic cement. Tests results show an insignificant reduction of slump on the concrete mixes, an increase of air content and a decrease in density and compressive strength resistance with increasing glass powder substitution.

  • LA CIUDAD DESDE LA CASA: Ciudades espontáneas en Lima

    Sáez Giraldez, Elia; García Calderon, José; Roch Peña, Fernando; [email protected] (Instituto de la Vivienda de la Facultad de Arquitectura y Urbanismo de la Universidad de Chile, 2014-10-16)
    In Lima, informal settlements emerge from the construction of straw houses in the desert under poverty and precarious conditions. However, after seven decades of existence, they have transformed into relatively integrated neighborhoods in the city, with considerable level of development. This article describes how an urban fabric emerges within inverted planning processes, from large to small scales, from the city to the house (urbanization-division-consruction), being this inversion the engine of its development. Straw houses, the only material that enables communities to settle in the territory, apart from offering shelter, have become a strategy for city making. Housing is either a workshop or a store, a contribution to the urban fabric; it also changes its functions according to the needs of dwellers; housing expands as the neighborhood densifi es, transforming its typology (from house to group home) or nature (rural to urban) when the settlement changes from village to neighborhood. The house expands as the city grows; both elements transform each other, giving dynamism to urban fabric, as well as ability to evolve.
