Peer Support and Outcome Expectations in STEM: Development and Validation of an Instrument

Identifying the factors that influence young Mexicans’ choice of career is essential to generate strategies able to attract new students to science, technology, engineering, and mathematics (STEM). The objective of this study was to develop and verify the psychometric properties (realibility and con...

description Identifying the factors that influence young Mexicans’ choice of career is essential to generate strategies able to attract new students to science, technology, engineering, and mathematics (STEM). The objective of this study was to develop and verify the psychometric properties (realibility and construct validity) of the scales “Student peer support” (APE-STEM) and “Outcome expectations” (EXREC-STEM) in high school students’ choice of STEM college degrees by generating a structural equation model. Likert scales were administered to 167 students from rural and urban schools in southeastern Mexico. The results of the exploratory and confirmatory factor analyses show adequate fit and an internal consistency of α = .82 and .84, confirming the empirical soundness of the model and leading to the conclusion that these scales are highly reliable for use in this context.

Identificar los factores que influyen en la elección de carrera de los jóvenes mexicanos resulta fundamental para generar estrategias que permitan atraer nuevos estudiantes al área de ciencia, tecnología, ingeniería y matemáticas (STEM, por sus siglas en inglés). El objetivo del estudio fue desarrollar y verificar las propiedades psicométricas (fiabilidad y validez de constructo) para las escalas Apoyo de pares estudiantiles (APE-STEM) y Expectativas de resultado (EXREC-STEM) en la elección de carreras universitarias STEM en estudiantes de nivel medio superior, generando un modelo de ecuaciones estructurales. Las escalas (tipo Likert) se aplicaron a 167 estudiantes de instituciones rurales y urbanas del sureste mexicano: los resultados de los análisis factoriales, exploratorio y confirmatorio muestran un adecuado ajuste, además de una consistencia interna de α = .82 y .84, confirmándose la solidez empírica del modelo, por lo que se concluye que las escalas son altamente confiables para su utilización en este contexto. Identificar os fatores que influenciam na escolha de carreira profissional dos jovens mexicanos é essencial para gerar estratégias que permitam atrair novos alunos para a área de ciência, tecnologia, engenharia e matemática (STEM, por sua sigla em inglês). O objetivo do estudo foi desenvolver e verificar as propriedades psicométricas (confiabilidade e validade de construto) das escalas Apoio de pares estudantis (APE-STEM) e Expectativas de resultado (EXREC-STEM) na escolha de cursos universitários STEM em estudantes do Ensino Médio, gerando um modelo de equações estruturais. As escalas (tipo Likert) foram aplicadas a 167 alunos de instituições rurais e urbanas do sudeste mexicano: os resultados das análises fatorial, exploratória e confirmatória mostram um adequado ajuste, bem como uma consistência interna de α = 0,82 e 0,84, confirmando-se a solidez empírica do modelo, pelo que se conclui que as escalas são altamente confiáveis ​​para a sua utilização neste contexto.
