Moodle and Socrative quizzes as formative aids on theory teaching in a chemical engineering subject

There is a majority opinion on the positive influence of using technologies in teaching. However, few studies account for their effect on students’ final grades. Traditional theory teaching often shows a lack of students’ motivation, engagement and self-efficacy. A way to improve these is to include quizzes, which may allow students to gain in skills acquisition feedback and self-regulation, and to control their own way to construct knowledge. The suggested methodology embeds quizzes and tests through two ICT, each one with a different strategy. One is the use of quick and real-time quizzes with Socrative, focused in promoting motivation and engagement in the classroom. The second is the use of tests with Moodle for a longer time scale (blocks of lessons). Both tests and quizzes were designed as formative activities: the students are able to gain feed-back, weaknesses identification and better programming of their work. Three ‘tools’ (one Moodle test; three Socrative quizzes; no tool/only traditional teaching) were rotated among three different cohorts and blocks in a Chemical Engineering subject (n=49 students). Effects on the students’ learning outcomes (grades) at the final theory exam were evaluated by blocks. A paired-data one-factor ANOVA test showed no significant statistical differences in using Moodle tests or Socrative quizzes or not. Some possible negative influences over data were identified and improvements for further study have been suggested. An intensification of quizzes and tests could be relevant. Although no significant improvement over grades was obtained, the use of both tools was positively valued for students and instructors. Surveys’ results showed that the proposed methodology may create a more attractive and self-regulated educational environment. However, this study supports that students’ previous perceptions about the tools may condition their final perceptions over the ICTs real aid for learning and their future academic outcomes.

The flip side of teaching process design and process control to chemical engineering undergraduates – And completely online to boot

Two core courses have been given for several years to senior chemical engineering undergraduate students in flipped format, combining pre-class online preparation by the students, “class meetings” with the lecturer, and “active tutorials,” in which groups of students solve exercises. In 2020/21, the COVID-19 lockdown imposed online teaching of these courses to the 54 enrolled students. The objective of work presented in this paper is to explore the impact of the remote flipped classroom design on students' learning experience and achievements, in comparison to the regular flipped class in which only the first preparation phase was online. Because the course was taught completely online, a plethora of data was for the first time made available to support a thorough study of the course teaching protocol, including data from Panopto Analytics®, Zoom and Moodle logs, extensive self-report surveys, as well as actual learning outcomes (exam results). Statistical analyses including multivariate regression were performed to determine which factors most affect learning outcomes. The student surveys indicate that of the three class steps, the “active tutorial” gives students the most confidence in their mastery. Furthermore, analysis indicates that active students think that they benefit more than do passive students, as reflected by both self-reporting and final exam performances. The importance of underlying ability, as indicated by the GPA is a principal conclusion from the regression model, which also identifies attendance of “active tutorials” as a dominant positive effect on exam grades. Two important conclusions of our work are that the online and face-to-face versions of our flipped approach achieve indistinguishable learning outcomes and that students’ perceived confidence in their mastery is highest after the active tutorial.
