This quasi-experimental study examines the effect of short instruction videos on students’ business statistics learning. Two hundred and thirty-one Dutch students attended 6-week online seminars on Business Statistics. One hundred and nineteen students were in an experimental group, and 112 in a control group. Students in the experimental group watched short instructional videos and studied online quizzes at their own pace. In the control group, students followed teachers’ instructions throughout the seminars. It was found students watching short videos significantly outperformed those following teachers’ virtual instruction. Short videos were especially useful for those who were good at math. The research sheds light on the design of hybrid learning, particularly for business statistics education at the university level.
Videos can enrich the learning environment in a variety of ways, adding value to the learning process. Using videos brings benefits to the students and to you as the lecturer, as long as you give proper thought to how you use them. The Research Group Teaching, Learning & Technology is conducting research into the effective use of videos in teaching.
BackgroundSeveral conditions and diseases can result in speech problems that can have a negative impact on everyday functioning, referred to as communicative participation. Subjective problems with acquired speech problems are often assessed with the speech handicap index (SHI). To assess generic participation problems, the Utrecht Scale for Evaluation of Rehabilitation–Participation (USER-P) questionnaire is frequently used. The English questionnaire Communicative Participation Item Bank—short form (CPIB short form) is a 10-item valid, reliable instrument that assesses communicative participation. In the absence of a Dutch equivalent, translation and validation of the CPIB short form was required.AimsTo translate the CPIB short form into Dutch, and to determine its psychometric properties for the group of adults with speech problems resulting from a neurological aetiology or head and neck cancer.Methods & ProceduresTranslation of the CPIB short form was performed following the instructions of the European Organisation for Research and Treatment for Cancer (EORTC). In a cross-sectional multi-centre study, participants completed the Dutch CPIB short form together with the SHI and USER-P, and the CPIB a second time after 2 weeks. We assessed internal consistency and test–retest reliability of the CPIB. Construct validity was assessed based on correlations with SHI, USER-P and speech assessments.Outcomes & ResultsIn the validation study, 122 participants were included: 51 with dysarthria due to different neurological disorders, 48 with speech problems due to head and neck cancer treatment and 23 healthy controls. Internal consistency of the items was high (Cronbach's alpha = 0.962), the intraclass correlation coefficient (ICC) for test–retest reliability was high 0.908 (95% CI = 0.870–0.935). Construct validity was supported by a strong correlation between the Dutch CPIB short form and the SHI total score (SHI total rs = 0.887) and a moderate correlation between the Dutch CPIB-10 and the USER-P subscales (USER-P Frequency rs = 0.365; USER-P restrictions and USER-P satisfaction rs = 0.546). A moderate correlation was found between the Dutch CPIB-10 and the speech performance assessments (degree of distortedness r = −0.0557; p ≤ 0.001; degree of intelligibility r = 0.0562).Conclusions & ImplicationsThe Dutch CPIB short form provides a valid and reliable tool for clinical practice and research purposes. It allows clinicians to start using this PROM in clinical and research practice to systematically investigate the impact of the speech problems on communicative participation in a Dutch-speaking population.What this paper addsWhat is already known on the subjectCommunicative participation allows people to take part in life situations, but can be affected by acquired speech problems. The CPIB is a patient-reported outcome measure for the assessment of this concept. For the English language the 46-item bank and a 10-item short form is available.What this paper adds to existing knowledgeThis paper describes the process of translation of the CPIB short form into Dutch, and confirms its reproducibility and validity.What are the potential or actual clinical implications of this work?With this validated Dutch version of the CPIB short form available, professionals can implement this tool in clinical and research practice to systematically evaluate communicative participation.
