Teachers and students need good learning environments to perform well. In this study, it is pre-supposed that the spatial properties of classrooms are important facilitators of the educational process. Ideally, school buildings in general and classrooms in particular should influence the educational process positively by providing a healthy and comfortable built environment. A healthy and comfortable indoor environment is provided by optimal conditions for IAQ, thermal comfort, acoustic comfort and visual comfort. A pleasant temperature, fresh air, good soundscape and lighting conditions will support the in-class tasks of lecturers and students. But do schools provide optimal environmental learning conditions? Maintaining adequate ventilation and thermal comfort in classrooms could significantly improve academic achievement of students. A first orientating literature study reveals that that classroom conditions are far from optimal and in some cases even unhealthy and affect the performance of teachers and students negatively. Overall, evidence suggests that poor indoor environment quality in schools is common and adversely influences the performance and attendance of students, primarily through health effects from indoor pollutants. Based on this evidence, it is highly recommended to improve environmental conditions in classrooms in higher education in The Netherlands by offering a better indoor air quality and thermal conditions and by improving the acoustic and lighting conditions.

Teachers and students need good learning environments to perform well. In this study it is pre-supposed that the spatial properties of classrooms can contribute to the quality of the educational process. Thermal, acoustic and visual conditions and indoor air quality (IAQ) may be extremely powerful in order to support the in-class tasks of teachers and students. But what are the optimal conditions? And do schools provide optimal indoor 2019 ISES ISIAQ Joint Annual Meeting – Abstracts | 362 environmental conditions? Research shows that adequate ventilation and thermal comfort in classrooms could improve academic performance of students. However, different studies also suggest that poor indoor environmental quality in classrooms are common and, in some cases, even unhealthy. This study investigates the relationship between indoor air quality (IAQ), perceived indoor air quality (PIAQ) and building-related symptomsof students in university classrooms via subjective assessment and objective measurement. This study was carried out in 59 classrooms of a university of applied sciences in the northern part of the Netherlands during heatingseason. Responses from 366 students were obtained through a questionnaire. Results shows that carbon dioxide concentrations (CO2) exceed minimum Dutch guidelines in 36% of the observed classrooms. Moreover, after a 40 minute class this raised to 45% of the observed classes. Poor IAQ can affect teachers and students level of attention, cause arousal and increase the prevalence of building-related symptoms. A significant correlation was found between CO2 concentrations and PIAQ and between PIAQ and the ability to concentrate, tiredness and dry skin. The research findings imply that increased CO2 concentrations will affect the PIAQ of students and may cause inability to concentrate, increased tiredness and dry skin. These building-related symptoms can cause distraction and affect the academic performance of students negatively. It is highly recommended to improve IAQ in classrooms by offering better indoor environmental conditions through reducing CO2 concentrations.

The indoor air quality (IAQ) in classrooms in higher education can influence in-class activities positively. In this context, the actual IAQ and students' perceived IAQ (PIAQ), perceived cognitive performance (PCP), and short-term academic performance (SAP) were examined in two identical classrooms during regular academic courses. During the lecture, key performance indicators (KPI) for the IAQ, i.e. carbon dioxide concentration, particulate matter 2.5, and total volatile organic compounds, were measured. After the lecture, responses of 163 students were collected with a validated self-composed questionnaire and a cognitive test, which covered topics discussed during the lecture. A significant association between the IAQ KPI and the PIAQ was found (p < .000). The PIAQ significantly predicted the PCP (p < .05) and the PCP significantly predicted the SAP score (p < .01). These results indicate that the IAQ in classrooms is associated with the PIAQ and PCP, and therefore is associated with students' SAP.

This study explores if multiple alterations of the classrooms' indoor environmental conditions, which lead to environmental conditions meeting quality class A of Dutch guidelines, result in a positive effect on students' perceptions and performance. A field study, with a between-group experimental design, was conducted during the academic course in 2020–2021. First, the reverberation time (RT) was lowered in the intervention condition to 0.4 s (control condition 0.6 s). Next, the horizontal illuminance (HI) level was raised in the intervention condition to 750 lx (control condition 500 lx). Finally, the indoor air quality (IAQ) in both conditions was improved by increasing the ventilation rate, resulting in a reduction of carbon dioxide concentrations, as a proxy for IAQ, from ~1100 to <800 ppm. During seven campaigns, students' perceptions of indoor environmental quality, health, emotional status, cognitive performance, and quality of learning were measured at the end of each lecture using questionnaires. Furthermore, students' objective cognitive responses were measured with psychometric tests of neurobehavioural functions. Students' short-term academic performance was evaluated with a content-related test. From 201 students, 527 responses were collected. The results showed that the reduction of the RT positively influenced students' perceived cognitive performance. A reduced RT in combination with raised HI improved students' perceptions of the lighting environment, internal responses, and quality of learning. However, this experimental condition negatively influenced students' ability to solve problems, while students' content-related test scores were not influenced. This shows that although quality class A conditions for RT and HI improved students' perceptions, it did not influence their short-term academic performance. Furthermore, the benefits of reduced RT in combination with raised HI were not observed in improved IAQ conditions. Whether the sequential order of the experimental conditions is relevant in inducing these effects and/or whether improving two parameters is already beneficial, is unknown.

Abstract This research presents a descriptive study regarding collaborative learning in a multicultural classroom at a vocational education school in The Netherlands. The study bridges two domains of research: research on culturally diverse learning environments - which has mostly concerned primary and general secondary education - and studies on collaborative learning. It analyzes current practices and perceptions of both teachers and students applying collaborative learning in a culturally diverse, competence-based learning environment. The results suggest that in a multicultural classroom, students, on the one hand, are mostly focused on their individual performance, resulting in poor collaboration among classmates. On the other hand, teachers seem unaware of their own role in affecting students' behavior and the influence of the cultural backgrounds of students on collaborative learning processes.

BackgroundWhile the indoor environmental quality of classrooms is a potential issue because it may affect the wellbeing of school children, the relations are still poorly studied. This study aimed to investigate the relations between classroom characteristics and health and comfort of school children.Material and methodsA questionnaire was distributed among 1311 school children (8–12 years old, average 10) of 54 classrooms at 21 schools in The Netherlands. Additionally, the survey included an inspection of the school and its installations and an inspection of the classrooms surveyed using checklists, and monitoring of some environmental parameters (temperature, relative humidity and CO2 concentration) in the classrooms.ResultsAmong the children studied, 87% was bothered by noise, 63% by smells, 42% by sunlight when shining, 35% didn't like the temperature in the classroom (too cold or too warm) and 34% experienced temperature changes. Main diseases reported comprised of allergies (26%), rhinitis (17%), hay fever (16%) and eczema (16%). Health and comfort in non-traditional schools was better than in the traditional schools studied (A non-traditional school is a school in which the way of educating children is different from the traditional way of education, according to a different educational theory). Physical building characteristics of the classrooms studied in the traditional schools were associated with the Classroom Symptom Index (location of school building, heating system, solar devices hampering opening windows or ventilation) and the Classroom Comfort Index (ventilation type, window frame colour, floor material and vacuum cleaning frequency).ConclusionsMeasures to improve acoustical, air, and thermal conditions of children in classrooms are needed. More research is required on the use of different lighting systems and use of different colours in classrooms.

This research presents a descriptive study on regarding the use of a research-based approach by teachers to clarify problems they encountered in multicultural classrooms. It analyses the outcomes of a training in which seven teachers from a Dutch Senior Secondary Vocational Education school participated conducting a research-based approach to explore the current practice of their multicultural classrooms. To determine the learning outcomes semi-structured interviews were conducted with the teachers with questions matching the domains of change in Clarke and Hollingsworth(2002) Interconnected Model of Teachers Professional Growth. Our main question was to what extent a research-based approach can help teachers to clarify the problems they encountered in their multicultural classrooms. According to the external domain of Clarke and Hollingsworth they become encouraged by sources of information from experts and literature. The teachers did not always have a positive attitude towards all research activities.

Collaborative learning in a culturally diverse secondary vocational education. By K. Tielman (Fontys), P. den Brok (ESoE), S. Bolhuis (Fontys) and R. van de Sande (Fontys) This contribution discusses a descriptive study on the experiences of students and teachers in secondary vocational education regarding collaborative learning (CL) in a culturally diverse context. The study bridges two domains of research: research on culturally diverse learning environments - which has mostly concerned primary and general secondary education (e.g. de Haan (2005), Hajer (1996), Radstake (2007) and studies on CL. The present study adds to the existing literature not only by integrating these two domains, but also by its specific focus on Dutch secondary vocational education and by focusing on multiple sources of evidence (both cognitions and actions; both student and teacher perspectives). The study analyzes current practices and perceptions of teachers and students with CL in a culturally diverse, competence-based learning environment. The sample consisted of 27 students (with 12 different cultural backgrounds) and two of their teachers (a mentor and a coach/tutor). Teachers and students were followed while working on a project-based series of lessons. Data collection consisted of two steps. In the first step, small groups of students and their teachers were observed and videotaped (allowing for simultaneous analysis of both verbal and non-verbal behaviors) during collaborative learning tasks. Based on these observations, semi-structured interviews were conducted with 9 groups of 3 students and the two teachers, focusing on topics of collaboration, communication, participation, coaching and conflicts, all of which derived from CL characteristics mentioned by Johnson & Johnson (1994). In the second step, video-stimulated (recall) interviews were conducted with both teachers. The interviews were based on a-priori defined moments selected by the teachers themselves and/or the researcher. The data was qualitatively analyzed in an interactive process between theory and data using the computer program Atlas-Ti. Codes were partially based on CL characteristics from the literature (Johnson & Johnson, 1994) and partially on focal points emerging from the observations/interviews. To establish reliability of the coding process, parts of the data were coded by a second researcher, leading to an inter-rater reliability (Cohen's kappa) of 0.87, and a percentage of agreement between both researchers of 81.5 on 54 valid fragments. The findings suggest three major themes behind the data: 1) individual accountability of the students; 2) the importance of the teacher/coach role; and 3) the aspect of (absence of) cultural consciousness. The results of the study suggest that on the one hand students are mostly focused on their individual performance and that there is poor collaboration among classmates while working on collaborative learning tasks, while on the other hand teachers seem unaware of their own role in affecting students' behavior and the influence of cultural backgrounds of students in the CL process. Despite the limitations of this study (a small number of participants, one single school and only one sector of secondary vocational education), the results of the study suggests that teachers of culturally diverse classrooms of the secondary vocational education must become more aware of their own roles as adaptive coaches and models and of the influence of multiculturality on CL. The full paper discusses the results and suggestions in detail.
