Validation of Student Peer Assessment of Effective Oral Communication in Engineering Degrees

Abstract

Peer assessment is a form of collaborative learning in which students evaluate learning products prepared by other students. We present the results of an analysis of the assessment of oral presentations by students. A group of students solves a problem, writes a document with the solution, and makes an oral presentation in class to other students. Another group assesses the written document and oral presentation. To help students perform the assessments two rubrics are provided along with other guidance documents that help in writing scientific documents and performing oral presentations. The rubric evaluates five factors of oral communication. The results of the student evaluations are compared with the simultaneous evaluations produced by two lecturers. When making a comparison of the global assessment between lecturers and students we find significant differences. However, when the factor 'use of auxiliary resources' is removed these differences disappear as the factor introduces a difficult to justify dispersion. In addition, the assessment performed by students with and without the help of a rubric is compared and no significant differences are found.

Assessment of transferable skills of engineering students

“…A maior parte dos estudos foi realizada em países da Europa (12 artigos), com destaque para a Espanha, onde foram realizados sete dos 25 trabalhos incluídos nesta revisão (Balderas et al, 2018;Meseguer-Dueñas et al, 2018;Sánchez Carracedo et al, 2018;Olmedo-Torre;Vidal, 2017;Balderas et al, 2015;Diez;Zárraga-Rodríguez;García, 2013;Pérez-Martínez et al, 2010). Em segundo lugar, aparecem os Estados Unidos com quatro pesquisas (Canelas;Hill;Novicki, 2017;Gill;Ritzhaupt, 2013;Zhang, 2012;Steiner et al, 2011).…”

“…Outros autores reforçam as limitações no que diz respeito à homogeneidade e ao pequeno tamanho das amostras consideradas (MESEGUER-DUEÑAS et al, 2018;Canelas et al, 2017;Abdullah et al, 2013;Gill;Ritzhaupt, 2013;Pérez-Martínez et al, 2010;Vidic, 2010). Observa-se nos estudos mais recentes (últimos três anos), o uso de amostras maiores, o que pode contribuir para a validação dos métodos propostos e permitir um uso mais abrangente dos instrumentos.…”

Case Study on Peer Assessment Performed by Engineering First Year Students

“…In a previous work [7], the task object of students peer assessment was some resolved problems, written submitted and oral presented in groups. Students were provided by an evaluation rubric in advance.…”
