World economic forum reported that creativity is one of the most sought after skills by employers globally. Preliminary research lead to multiple initiatives on enhancing creativity and innovation. To contribute in this field, we investigated the effect of two interventions on the creativity of undergraduate engineering students, particularly on engineering design concept generation. The primary focus of this investigation was on assessing the effect of two interventions, combining and classifying concepts, on the originality and quantity of the concepts produced. In this research, we used the Decision Tree for Originality Assessment in Design (DTOAD) as a measure of concept originality. Statistical analysis showed that both the combine and the classify interventions lead to concept generation with higher originality. We also found that students produced higher number of the radically different concept, i.e. concepts with originality score 7.5 and above, however this effect was observed in all the test groups. These interventions made improvements and thus can be encouraged as a part of an ideation or an engineering problem solving task in the undergraduate engineering education to help the students develop creative skills.

Creativity is the essential driving force, and creative engineers are the drivers entrusted to propel the technology-driven industry to the pinnacle of innovations in all engineering sectors. Accordingly, creativity is being integrated into engineering education in different ways, from a single lecture to more extensive curriculum level approaches. In this paper, we measured the effect of a multidisciplinary project course, a joint effort between the School of Arts, Design and Architecture, and the School of Engineering, on students’ creativity. In particular, we assessed the Originality, Novelty, and Quantity of solutions produced by participants in two tasks, an Alternate uses test and the ShapeStorm exercise. An alternate uses test assessed the written form of divergent thinking, and the ShapeStorm exercise assessed the visual form of divergent thinking. Statistical analysis of the data indicated that solutions for the written divergent thinking task produced by students post-course were more novel than pre-course. We did not find a statistically significant improvement in the Quantity. Similarly, for the visual divergent thinking task, we see no statistically significant increase.

Ideation methods have been extensively studied, and several ideation methods can be beneficial in different contexts, but it is not understood what makes a specific method work. Previous work has shown that all the ideation methods comprise of 25 fundamental ideation mechanisms in two categories: idea implementation and idea promoting mechanisms. In this study, we try to understand how individual mechanisms affect idea generation outcomes. We chose four idea promoting mechanisms: two from the process category (Classification & Combination) and two from the idea sources category (Building on Others and Stimulation). These mechanisms were selected as they are examples of comparable mechanisms that could easily be integrated into any other ideation method. We conducted four experiments and assessed idea quantity, novelty, and originality. Our study showed that the chosen mechanism increased ideation performance. For the most part, the mechanisms are statistically equivalent, but we found evidence that classification outperforms combination in a simple ideation exercise. We also found the building on others can be more useful than the type of stimulation used in engineering concept generation, but the difference was not found in a simple ideation exercise. Overall, we find evidence that all mechanisms improve ideation effectiveness and could be incorporated into any ideation method, but further studies are needed to build more comprehensive understanding
