Annoyance and health symptoms and their influencing factors: A population-based air pollution intervention study

OBJECTIVES Interventions for reducing air pollution are important means for improving public health. The role of psychological factors in understanding annoyance and health symptoms due to air pollution is limited and further investigation is required. This study aimed to investigate the effects of an intervention to reduce air pollution (predominantly dust and soot) with respect to perceived pollution, risk perception, annoyance and health symptoms. Another objective was to test a model that describes inter-relations between air pollution, perceived pollution, health risk perception, annoyance and health symptoms. STUDY DESIGN An interventional, population-based questionnaire study. METHODS Surveys were performed before (pre-test) and after (post-test) closure of a sinter plant. Instead, pellets were shipped to the communitys harbour for steel production. Individuals in the community aged 18-75 years were selected at random for participation in the pre-test (n=738; 74% of the sample participated) and post-test (n=684; 68% of the sample participated). The two samples were representative of the populations at the two points in time, and thus not identical. RESULTS After the sinter plant was closed, the environment was perceived as being less dusty, the residents were more positive in their risk perception, and they reported less annoyance due to dust, soot and odorous substances. No difference was found for health symptoms between the pre-test and the post-test. Based on path analyses, a model is proposed of inter-relations between air pollution, perceived pollution, health risk perception, annoyance and health symptoms. CONCLUSION The intervention was successful with respect to perceived dust and soot pollution; to annoyance attributed to dust, soot and odorous substances; and to risk perception. The path analyses suggest that perceived pollution and health risk perception play important roles in understanding and predicting environmentally induced annoyance and health symptoms.

Assessment of prior learning in higher education: a review from a validity perspective

The process of giving official acknowledgment to formal, informal and non‐formal prior learning is commonly labelled as assessment, accreditation or recognition of prior learning (APL), representing a practice that is expanding in higher education in many countries. This paper focuses specifically on the assessment part of APL, which undoubtedly is central to the whole process, through a review of research in this area and an analysis of the reviewed studies from a validity perspective. The research reviewed (published 1990–2007) is categorised into empirical as well as more theoretically oriented publications, with a quantitative dominance of the latter. According to the validity analysis, a majority of the studies conducted in this area relate to the evidential basis of test interpretation and use, primarily providing theoretical rationales and theories for a variety of practices. The consequential basis of test interpretation and use has not been studied to any larger extent, resulting in a lack of both theoretical and empirical studies dealing with this aspect of validity.

Validity of admission decisions based on assessment of prior learning in higher education

Assessment of prior learning (APL) refers to the process of validating individuals’ learning in a variety of contexts, representing a relatively new practice in many countries. In higher education, APL is used to receive access and credits based on skills and knowledge acquired mainly outside of formal academic settings. This paper focuses on validity of admission decisions based on this type of assessment in higher education. The study examines decisions made by higher education institutions for approximately 600 applicants who have used APL in order to receive admission to, and credits in the vocational teacher education programme in Sweden. The results are analysed and presented in relation to a validity discussion. A conclusion is that the existing practice of APL needs improvements in order to obtain validity and trustworthiness in the decisions made in relation to APL.

Effects of Repeated Testing on Short- and Long-Term Memory Performance across Different Test Formats.

This study examined whether practice testing with short-answer (SA) items benefits learning over time compared to practice testing with multiple-choice (MC) items, and rereading the material. More specifically, the aim was to test the hypotheses of retrieval effort and transfer appropriate processing by comparing retention tests with respect to practice testing format. To adequately compare SA and MC items, the MC items were corrected for random guessing. With a within-group design, 54 students (mean age = 16 years) first read a short text, and took four practice tests containing all three formats (SA, MC and statements to read) with feedback provided after each part. The results showed that both MC and SA formats improved short- and long-term memory compared to rereading. More importantly, practice testing with SA items is more beneficial for learning and long-term retention, providing support for retrieval effort hypothesis. Using corrections for guessing and educational implications are discussed.

Group discussions and test-enhanced learning: individual learning outcomes and personality characteristics

ABSTRACT This paper focuses on the factors that are likely to play a role in individual learning outcomes from group discussions, and it includes a comparison featuring test-enhanced learning. A between-groups design (N = 98) was used to examine the learning effects of feedback if provided to discussion groups, and to examine whether group discussions benefit learning when compared to test-enhanced learning over time. The results showed that feedback does not seem to have any effect if provided to a discussion group, and that test-enhanced learning leads to better learning than the discussion groups, independent of retention interval. Moreover, we examined whether memory and learning might be influenced by the participants’ need for cognition (NFC). The results showed that those scoring high on NFC remembered more than those who scored low. To conclude, testing trumps discussion groups from a learning perspective, and the discussion groups were also the least beneficial learning context for those scoring low on NFC.

Agreement in assessment of prior learning related to higher education: an examination of interrater and intrarater reliability

This article focuses on reliability in assessment of prior learning (APL) related to higher education. APL refers to a process where adults’ prior learning, formal as well as informal, is assessed and acknowledged. In higher education, APL is used for the purpose of gaining admission, advanced standing or credits. In this article, studies investigating reliability in APL are presented. The studies provide data of inter- and intrarater reliability among assessors in a specific APL scheme used in higher education. Percentage of agreement and Cohen’s kappa were used to estimate reliability, and the results show that the agreement between assessors, i.e. interrater reliability, is poorer compared to the agreement on repeated assessment by the same assessor, i.e. intrarater reliability. Further, the results reveal that there are differences in agreement between different aspects of prior learning. A conclusion is that reliability in this type of assessment ought to be further investigated.

Group Differences in Test-Taking Behaviour: An Example from a High-Stakes Testing Program.

Abstract This study investigated whether different groups of test-takers vary in their reported test-taking behaviour in a high-stakes test situation. A between-group design (N = 1129) was used to examine whether high and low achievers, as well as females and males, differ in their use of test-taking strategies, and in level of reported test anxiety and motivation. The results showed differences between high and low achievers on a number of test-taking strategies, where high achievers reported using successful strategies to a higher extent. There were also gender differences: females, for example, reported using random guessing to a higher extent than males. Further, low achievers, especially females, reported significantly higher levels of test anxiety than high achievers, and high achievers reported slightly higher levels of motivation when compared to low achievers. To conclude, test-taking behaviour might bring additional variance to test scores, whether or not this is irrelevant variance is discussed.

Threats to the valid use of Assessment of Prior Learning in higher education: claimants’ experiences of the assessment process

Assessment of Prior Learning (APL) refers to a process where adults’ prior learning, formal as well as informal, is assessed and acknowledged. In the first section of this paper, APL and current conceptions of validity in assessments and its evaluation are presented. It is argued that participants in the assessment are an important source of information for the validation of the assessment. In the following section participants’ experiences from a particular APL scheme are evaluated using a questionnaire developed for that purpose. The questionnaire provides data on individuals’ perceptions of the procedure and result of the APL scheme. The results are described, analysed and discussed from a validity perspective. Conclusions drawn from the results are that possible threats to validity can exist in the administration of APL procedures, as well as in consequences of APL.

The Testing Effect and Its Relation to Working Memory Capacity and Personality Characteristics

Retrieval practice is known to lead to better retention of a to-be-learned material than restudy (i.e., the testing effect). However, few studies have investigated retrieval practice in relation to working memory capacity (WMC) and personality characteristics such as grittiness (Grit) and need for cognition (NFC). In two experiments, we examined retrieval practice and restudy of Swahili–Swedish word pairs in relation to individual differences in Grit and NFC. In Experiment 1, using a between-subjects design, a significant main effect of retention interval was qualified by a Group × Retention Interval interaction. However, there were no effects of Grit or NFC. In Experiment 2, a within-subjects design was used, and a measure of WMC was included. The analyses revealed a testing effect; but again, WMC, Grit, and NFC were not significantly associated with performance. These results indicate that retrieval practice levels out the playing field regarding WMC, NFC, and Grit.

Assessing the Willingness to Elaborate among Young Students : Psychometric Evaluation of a Swedish Need for Cognition Scale

The personality trait Need for Cognition (NFC) has been studied for many years, and found to be important for individuals’ educational achievement. The original NFC-scale was developed in the eighties, and during the following decade the scale was translated and adapted into a number of other languages. A renewed interest for the personality trait of NFC has made these scales interesting to use. It is though vital that instruments used for studies of individual differences in the area of educational research, or in any other area, can portray valid results today. The aim of the present paper was to evaluate validity and reliability of the short version of the Mental Effort Tolerance Questionnaire, a Swedish adaption of the NFC-scale made in 1991, which has not been previously evaluated. This study involved 420 young students, and the evaluation of reliability includes a study of temporal stability (test-retest), as well as internal stability. Further, the evaluation of validity includes construct and criterion validity. Regarding reliability, the results showed a test-retest reliability coefficient of .88 (n = 108), and an internal stability (Cronbach’s alpha) of .88 (n = 420). Evaluation of construct validity found evidence for a five factor dimensional structure (n = 420), discriminant validity to measures of general intelligence (r = .25; n = 122), working memory (r = .22; n =164), and the personality trait Grit (r = .26; n = 169). Finally, criterion validity was found for grades (r =.35; n =125). Overall, the results of the evaluation show that the inferences made from the results of the short version of the Swedish NFC-scale exhibits satisfactory reliability and validity, suggesting that the questionnaire can be used in educational contexts. The questionnaire might, however, benefit from being even more shortened.
