The importance of developing and assessing student critical thinking at university can be seen through its inclusion as a graduate attribute for universities and from research highlighting the value employers, educators and students place on demonstrating critical thinking skills. Critical thinking skills are seldom explicitly assessed at universities. Commercial critical thinking assessments, which are often generic in context, are available. However, literature suggests that assessments that use a context relevant to the students more accurately reflect their critical thinking skills. This paper describes the development and evaluation of a chemistry critical thinking test (the Danczak–Overton–Thompson Chemistry Critical Thinking Test or DOT test), set in a chemistry context, and designed to be administered to undergraduate chemistry students at any level of study. Development and evaluation occurred over three versions of the DOT test through a variety of quantitative and qualitative reliability and validity testing phases. The studies suggest that the final version of the DOT test has good internal reliability, strong test–retest reliability, moderate convergent validity relative to a commercially available test and is independent of previous academic achievement and university of study. Criterion validity testing revealed that third year students performed statistically significantly better on the DOT test relative to first year students, and postgraduates and academics performed statistically significantly better than third year students. The statistical and qualitative analysis indicates that the DOT test is a suitable instrument for the chemistry education community to use to measure the development of undergraduate chemistry students’ critical thinking skills.

Education Outcomes

Purpose – The purpose of this paper is to assess the effectiveness of a new general education program at Qatar University (QU) in achieving English writing and critical thinking outcomes. Design/methodology/approach – Collegiate Assessment of Academic Proficiency (CAAP) test was used as direct assessment tool to identify the extent to which QU students are making progress with respect to general education outcomes, and how well QU students perform compared to US students on general education outcomes that are measured by the CAAP test. Findings – Findings show evidence that students make progress in English and critical thinking during their QU educational careers. However, QU students lag well behind their US counterparts in writing skills, but they performed relatively better in critical thinking and essay writing. Research limitations/implications – The sample of students tested was limited to students who met certain criteria. Therefore, the sample was neither representative nor random and does not reflect the performance of the entire student body. English is a second language for most QU students, and cultural differences as well as students’ high school preparation and quality of faculty at QU add to the complexity of the study. Practical implications – Research finding may have implication on the general education program curriculum plan, assessment process, assessment plan and tools. It may also trigger comprehensive review of courses addressing writing and critical thinking skills. Moreover, the findings will have impact on institutional total approach and support to retain and enhance some of the cornerstone skills that general education program promise to achieve. The pilot study, results and findings can have implications on similar GCC general educations programs that focus on English writing and critical thinking skills. Originality/value – This original pilot study indicates a need for improvement of internal assessment processes and reconsideration of general education program courses contributing to skills examined. It also provides evidence on students’ performance on two important generic skills, both are important for QU and its stakeholders. The study’s findings are of broad interest to assess the efficacy of internal assessment at international institutions using an internationally available standardized test.
