Exploring the impact of formative feedback and drafts on final marks in a diploma level science report assessment

The ability to communicate experimental findings in scientific report format is considered an essential skill for scientists but many undergraduate students struggle with mastering this skill. Many tertiary educators now provide science literacy resources and draft report feedback to support student success. Despite these efforts, it is often reported that students resist engaging with draft feedback. We investigated the impact of various formative draft feedback approaches to evaluate their outcomes on (i) student engagement and (ii) final report mark. It was hypothesised that embedding mandatory drafts and feedback interaction should lead to improved final report quality because students would be more engaged with a reflective feedback process. Draft and final report grades were analysed using R Studio. Data exploration and statistical testing were completed using ggplot2 and base R functions. The results did not consistently support the hypothesis that draft submission increased final report score. The combined mean report score for students who submitted or did not submit a draft was found to be similar overall (n = 640, t = 0.43, df = 639, p-value = 0.67). These results suggest that draft feedback does not of itself lead to improved student engagement with supplementary help resources or final report grade

Driving students towards their best- an integrated approach to science reports

Background The ability to accurately and logically write up experimental findings in scientific report form is a skill that all tertiary science students need to master. However, many students strongly dislike report writing and resist engaging with supplementary help resources. Consequently, many students often aim for ‘satisfactory’ rather than ‘excellent’ in such written assignments – a position that is usually in directly opposition to that of their instructors. Aims Here we report on an integrated approach that aimed to: (i) better engage Diploma level tertiary science students in the scientific report writing process, and (ii) encourage students to write reports of a high (rather than a satisfactory) standard. Design and methods Short written activities were embedded before, during and after a practical laboratory exercise that later formed the basis of a longer, more formal scientific report. Students were required to conduct preliminary research prior to attending a practical laboratory class at James Cook University, Queensland. Students collected experimental data in a laboratory, and reported their methods, discussions and conclusions in short answer form. Students received formative feedback on their laboratory work from peers and lecturers and the revised work was then directly incorporated into a formal report framework. The students then expanded on this work and submitted it as a formal, 1500 word scientific report, worth 25% of their overall grade. To encourage students to aim for a high level of work, a minimum grade of Distinction (75%) was necessary in order for them to receive a grade for the assignment. Students who received less than 75% were not given a grade but were permitted to resubmit their reports on the proviso that they: (i) attended a 15-minute consultation to discuss their report submission, and (ii) submitted a written paragraph outlining how they had responded to feedback on their original report. Results The quality of work submitted was greatly improved on previous semesters where students were required to submit a draft for grading and feedback prior to submitting their final scientific report. Student engagement with online help resources was also much higher. Whilst marking time was substantially increased for the first report submission in comparison with drafts marked in previous semesters, marking time for the final report was greatly reduced. Conclusions Setting a high initial grading standard for students, withholding less than excellent ‘draft’ grades and integrating a stepwise writing approach to science report writing resulted in significantly higher student grades and resource interaction than previous, more traditional approaches
