Digital badges are emerging as an
approach to offer microaccreditation
for student achievements obtained in ongoing course work. They act
to offer a formal recognition and framework for multiple small components
which together make a significant contribution to student learning.
Badges are promoted as a way of highlighting these particular components.
The process of awarding a badge relies on evidence, typically in digital
form, such as video. In this article, we report on the implementation
of digital badges in high school chemistry for the teaching and accrediting
of achievement in laboratory skills. Pupils watched videos prior to
the classroom to assist them in preparation for a demonstration activity.
In the classroom, students demonstrated the laboratory technique to
a peer while the peer videoed the demonstration on a mobile phone.
This video was then used to review the demonstration by both peers
and teacher, and once the technique was considered satisfactorily
demonstrated, a badge was awarded. As well as development of laboratory
technique, the badging process facilitated the formal incorporation
of oracy into the classroom. Demonstration required narration, and
review required discussion between peers as well as discussions arising
out of the demonstration with the teachers. We report here how the
activities were organized, along with perceptions from students and
teachers regarding the value of this approach in the classroom.
The present paper reports upon the design and implementation of a novel practical work pedagogy that is shown to increase students’ retention of practical procedures. The chemistry exams, for 15 to 16-year olds in England, will be assessed entirely through terminal examination questions from 2018. Longer term retention of learning is critical if these students are to minimise any discrepancy in attainment that may arise from following curricula with a coursework component. The novel design, underpinned by Cognitive Load Theory and Social Constructivism, involves pre-laboratory preparation and employs oracy to promote thinking during practical work. Three equivalent chemistry groups within the same school undertook neutralisation and crystallisation practical tasks and their practical work exam question attainment data is analysed. The novel pedagogy is trialled as a neutralisation task with one group and affective outcomes are determined through Likert scale activity feedback questionnaire. Attainment data shows a statistically significant higher mark in practical exam question attainment for the intervention compared to the control group when tested ten weeks after the teaching episode.
