The COVID-19 pandemic kick-started a new paradigm shift in the way and manner teaching and learning takes place on the global scale due to the lockdown that succeeded in shutting down school activities. As a result, most institutions turned to technology supported e-learning as against the traditional face-to-face teaching and learning in order to…

Experimental designs in the social sciences have received increasing attention due to their power to produce causal inferences. Nevertheless, experimental research faces limitations, including limited external validity and unrealistic treatments. We propose combining qualitative fieldwork and experimental design iteratively--moving back-and-forth…

The field of geometrical optics features a broad knowledge base concerning conceptual learning difficulties and student conceptions. However, in contrast to other areas of physics, no widely used standard test instrument exists to assess middle school students' conceptual knowledge of geometrical optics. This is even more true for other areas of…

The researcher, who pretests a questionnaire conventionally, is confident that a small number of interviews reveals numerous problems afflict the questionnaire. The standardized interviewer is asked to observe respondent's verbal behaviors in order to realize whether respondent misunderstands question. But this strategy fails when respondent does…

Behavior coding is used to detect issues in questionnaires by flagging interactions between survey respondents and interviewers when their interactions deviate from standardized interviewing. It has become a popular method for evaluating survey questionnaire quality and has been used mostly in Western countries, with little research being done in…

The feedback between vocational education and training (VET) and the labour market can provide important input for the review and renewal of qualifications. A feedback loop that is based on learning outcomes helps provide deeper insights into what is required on the labour market, what is offered in training provisions and assessed at the end of a…

The development of questionnaires, surveys and psychometric scales is an iterative research process that includes a number of carefully planned stages. Pretesting is a method of checking that questions work as intended and are understood by those individuals who are likely to respond to them. However, detailed reports of appropriate methods to…

Learning objectives (LOs) are statements that typically precede a study session and describe the knowledge students should obtain by the end of the session. Despite their widespread use, limited research has investigated the effect of LOs on learning. In three laboratory experiments, we examined the extent to which LOs improve retention of…

Cognitive interviewing is a method to develop culturally appropriate survey questions and scale items. We conducted two rounds of cognitive interviews with 24 pregnant women in Ethiopia and Kenya to assess the appropriateness, acceptability, and comprehension of general and micronutrient supplement adherence-specific social support scales. We…

The development of computational thinking is a major topic in K-12 education. Many of these experiences focus on teaching programming using block-based languages. As part of these activities, it is important for students to receive feedback on their assignments. Yet, in practice it may be difficult to provide personalized, objective and consistent…

Relating mathematical concepts to graphical representations is a challenging task for students. In this paper, we introduce two visual strategies to qualitatively interpret the divergence of graphical vector field representations. One strategy is based on the graphical interpretation of partial derivatives, while the other is based on the flux…

The composite face paradigm (Young, Hellawell, & Hay, 1987) is widely used to demonstrate holistic perception of faces (Rossion, 2013). In the paradigm, parts from different faces (usually the top and bottom halves) are recombined. The principal criterion for holistic perception is that responses involving the component parts of composites in…

In this paper we present a system aimed at demonstrating the photoacoustic (PA) effect for educational purposes. PA imaging is a hybrid imaging modality that requires no contrast agent and has a great potential for spine and brain lesion characterisation, breast cancer and blood flow monitoring notably in the context of fetal surgery. It relies on…

It is now well accepted that working in research teams that span universities, jurisdictions and countries can be rewarding and economically prudent. To this end, investigators collaborate in the pursuit of knowledge to address human and societal problems and translate results into local and global contexts. This implies that investigators need to…

In this study, we investigated whether incorporating eye tracking into cognitive interviewing is effective when pretesting survey questions. In the control condition, a cognitive interview was conducted using a standardized interview protocol that included pre-defined probing questions for about one-quarter of the questions in a 52-item…
