- PublicationDevelopment and Validation of an E-Learning Education Model in the COVID-19 Pandemic: A Case Study in Secondary Education(MDPI AG, 2022-10) Martínez Gómez, Mónica; Bustamante García, Eliseo; Berna Escriche, César; Facultad de Administración y Dirección de Empresas; Dpto. de Estadística e Investigación Operativa Aplicadas y Calidad; Instituto Universitario de Investigación de Ingeniería Energética; Escuela Técnica Superior de Ingeniería Industrial; Centro de Gestión de la Calidad y del Cambio[EN] E-learning was crucial during the global lockdown. In this way, this article aims to propose and validate a holistic framework in which all the E-learning services are needed to ensure their effective implementation and use. To this end, an original 3S-T model, to measure E-learning success based on self-student assessment, was developed. This innovative model, which reinforces the existing theoretical framework of models, identifies a wide array of success predictors and relates them to various measures that help to reach success, including learning and academic achievements. The validation of the 3S-T model was carried out using the partial least squares structural regression equations modeling technique (PLS-SEM). In this analysis, four major constructors were identified as determinants of E-learning service performance, namely, the surrounding conditions, system characteristics, tutor's development and student's own performance. Although each of them is composed of several subcategories, finally, 15 indicators that estimate the fulfillment of these factors were defined and evaluated. The present study is strongly connected to the fourth goal of the Agenda established by the United Nations, which seeks Quality Education to ensure the sustainable development of countries.
- PublicationThe measurement invariance of job diagnostic survey (JDS) across three university student groups(OmniaScience, 2016) Martínez Gómez, Mónica; Marín García, Juan Antonio; Girado O'Meara, Martha; Dpto. de Organización de Empresas; Facultad de Administración y Dirección de Empresas; Dpto. de Estadística e Investigación Operativa Aplicadas y Calidad; Escuela Técnica Superior de Ingeniería Industrial; Centro de Gestión de la Calidad y del Cambio; Grupo de Investigación en Reingeniería, Organización, trabajo en Grupo y Logística Empresarial - ROGLE[EN] Purpose: The main purpose of this study is to apply a multigroup confirmatory analysis to examine the measurement invariance (MI) of the adapted version of the Job Diagnosis Survey (JDS) as a measurement tool that analyses the relationship between the features of teaching methodologies with university students’ motivation and satisfaction across data collected on different degrees and academic years. Design/methodology/approach: Confirmatory factor analysis was carried out using a multigroup structural equation model, using the program EQS 6.1 to test the invariance of the adapted version of JDS in a sample constituted by 535 student of a Spanish public university. The assessment of invariance included the levels of configural, metric, scalar, covariance and latent variables invariance. Several goodness-of-fit measures were assessed. Findings: The results show that measurements are equivalent at the configural, metric, covariance and latent factors invariance. Although the hypotheses of scalar invariance is rejected, results suggest that JDS is partial strict invariant and has satisfactory psychometric properties on all samples. Research limitations/implications: The sample is framed in university students aged between 18 and 30 and for a questionnaire on teaching methodology and students' satisfaction in the context of a Spanish university and the generalization to other questionnaire, or population, should be proved with specific data. Furthermore, the sample size is rather small. Originality/value: In the current process of change that is taking place in universities according to the plan developed by the European Space of Higher Education, focused on increasing the student skills, validate instruments as the satisfaction scale of JDS, are necessary to evaluate students’ satisfaction with new active methodologies. These findings are useful for researchers since they add the first sample in which the MI of a student’s satisfaction survey is tested.

- PublicationAssessing the Efficiency of Public Universities through DEA. A Case Study(MDPI AG, 2017-08-11) Visbal-Cadavid, Delimiro; Martínez Gómez, Mónica; Guijarro Martínez, Francisco; Facultad de Administración y Dirección de Empresas; Dpto. de Estadística e Investigación Operativa Aplicadas y Calidad; Dpto. de Economía y Ciencias Sociales; Instituto Universitario de Matemática Pura y Aplicada; Centro de Gestión de la Calidad y del Cambio; Generalitat Valenciana[EN] This paper presents the results of an efficiency study of Colombian public universities in 2012, conducted using the methodology of Data Envelopment Analysis (DEA) and the models CCR, BCC and SBM under output orientation. The main objective is to determine technical, pure technical, scale and mix efficiencies using data acquired from the Ministry of National Education. An analysis of the results shows the extent to which outputs of inefficient Higher Education Institutions (HEIs) could be improved and the possible cause of this inefficiency. The universities were also ranked using a Pareto efficient cross-efficiency model and a study was made of changes to overall productivity between 2011 and 2012. The results showed Tolima, Caldas and UNAD to be the best-performing universities, with Universidad del Pacífico as the worst performer. Malmquist index was applied to analyze the change in productivity from 2011 to 2012. The Universidad de La Guajira showed great improvement in technical efficiency between 2011 and 2012.

- PublicationRedesigning work in university classrooms: factors related to satisfaction in engineering and business administration students(OmniaScience, 2014) Marín García, Juan Antonio; Martínez Gómez, Mónica; Giraldo O’Meara, Martha; Dpto. de Organización de Empresas; Facultad de Administración y Dirección de Empresas; Dpto. de Estadística e Investigación Operativa Aplicadas y Calidad; Escuela Técnica Superior de Ingeniería Industrial; Centro de Gestión de la Calidad y del Cambio; Grupo de Investigación en Reingeniería, Organización, trabajo en Grupo y Logística Empresarial - ROGLEPurpose: We analyze how it affects the teaching model to motivational potential of the course and student satisfaction. Design/methodology: Using structural equation modeling (SEM) has analyzed data from a cross-section (2008, 2009 and 2010) of 535 students of industrial engineering and business administration, a Spanish public university. Findings: The results, using a validated instrument adapted to the teaching world, demonstrate the association between the characteristics of the type of student work, the motivating potential of the subject and satisfaction. Research limitations/implications: The Identity scale does not have good fit and the results should be considered tentative. The sample is limited and does not allow to generalize the findings, it should be extended in the future to include other universities and graduate students. Originality/value: This work confirm that the JDS model adapted to teaching is met. We found that the variety, identity, significance, autonomy, job feedback and social feedback are elements of a second-order construct representing the motivating potential of the subject and that the values of this construct are positively related, significantly and substantially to the overall satisfaction perceived by the student. We have also found that these relationships are maintained on samples of students from different years or rather different degrees. As a result, education professionals can use the model for analysis and redesign of jobs to help foster motivation and student satisfaction.
