“…The total normalized gain at 0.40 ± 0.21 is satisfactory and comparable to similar research projects (cf. 0.35 ± 0.21 in [34] (p. 156) or 0.37 ± 0.18 in [33] (p. 68)). The smallest learning gain was approximately 6% as indicated by the boxplot of g total in Figure 3, thus a non-negative impact can be recorded for all participants.…”

Exploring Learning Difficulties in Abstract Algebra: The Case of Group Theory

In an earlier contribution to Education Sciences we presented a new concept inventory to assess students’ conceptual understanding of introductory group theory—the CI2GT. This concept inventory is now leveraged in a pretest-post-test design with N=143 pre-service teachers to enrich this body of work with quantitative results. On the one hand, our findings indicate three recurring learning difficulties which will be discussed in detail. On the other hand, we provide a summative evaluation of the Hildesheim Teaching Concept and discuss students’ learning gain in different sub-domains of group theory. Together, the results allow for an empirical perspective on educational aspects of group theory and thus bridge the gap between qualitative and quantitative research in this field which constitutes a desideratum to date.

“…Lastly, in this article, we understand adequate conceptual understanding to be achieved by students who scored at least 50% of the total post-test score as has been achieved in prior research (cf. [34]). In this regard, it is important to note that for the clarification of the first part of RQ1 the pretest score is not relevant.…”

“…An exploratory interview study identifying N = 25 students' difficulties regarding different quantum optics content domains is reported in Ref. [55]. In [55], it was shown that (a) students are predominantly unprejudiced towards the experimental and technical foundations of quantum optics experiments, e.g., with regard to the preparation of single-photon states in experiments with heralded photons via coincident events on binary detectors, and that (b) most of the students can cope with the underlying principles [55].…”

“…• a part of the learners interpret single-photon interference via photons that divide and then overlap with themselves [55] (p. 216); • a part of the respondents equate photons with waves and conclude from this the necessity of observing interference phenomena [55] (p. 221); • some learners claim that the photons' localization would fail due to the small size of the photons [55] (p. 227); • furthermore, a part of the participants believe that quantum anticorrelation at a beam splitter cube would be caused by photons behaving like haptical particles, being either reflected or transmitted [55] (p. 232).…”

Quantum technologies have outgrown mere fundamental research in laboratories over recent years, and will facilitate more and more potentially disruptive applications in a wide range of fields in the future. In foresight, qualification opportunities need to be implemented in order to train qualified specialists, referred to as the future quantum workforce, in various fields. Universities world-wide have launched qualification programmes for engineers focusing on quantum optics and photonics. In many of these programmes, students attend courses on quantum physics contextualized via quantum optics experiments with heralded photons, because: (1) their experimental and physical foundations may be directly leveraged to teaching a number of quantum technology applications, and (2) physics education research has provided empirical evidence, according to which such quantum optics-based approaches are conducive to learning about quantum concepts. While many teachers are confident about the effectiveness of their concepts, there is little empirical evidence due to the lack of content-area-specific research tools. We present a 16-item concept inventory to assess students’ conceptual understanding of quantum optics concepts in the context of experiments with heralded photons adopted from a test instrument published in the literature. We have administered this Quantum Optics Concept Inventory as a post-test to N=216 students after instruction on quantum optics as part of an undergraduate engineering course. We evaluated the instruments’ psychometric quality, both in terms of classical test theory, and using a Rasch scaling approach. The Quantum Optics Concept Inventory enables a reliable measure (α=0.74), and the data gathered show a good fit to the Rasch model. The students’ scores suggest that fundamental quantum effects pose striking learning hurdles to the engineering students. In contrast, most of the students are able to cope with the experimental and technical foundations of quantum optics experiments with heralded photons and their underlying principles, such as the coincidence technique used for the preparation of single-photon states. These findings are in accordance with prior research, and hence, the Quantum Optics Concept Inventory may serve as a fruitful starting point for future empirical research with regard to the education of the future quantum workforce.
