Learning Economics at a distance: Quality and impact of expertise. A study with Open University students.

The research reported in this article is, considering the hypotheses, a replication of an earlier investigation with a different experimental population and in a different experimental setting. Where, in the earlier study, regular university students were involved, in the present study we focus on students studying in a distance education and open learning setting. One of the methodological difficulties with this research population is to reach a large and representative sample. As a consequence, the experimental group in the present study is limited in number, thus denying access to statistically significantly results in relation to all hypotheses tested.

Notwithstanding these methodological difficulties, the results are helpful to draw conclusions in relation to the quality and impact of expertise. As in the earlier study, attention was paid to the construction of a set of tests to grasp the complex nature of prior knowledge at the content level. The instruments used during the earlier study were improved in relation to their psychometric qualities.

Concerning the hypotheses about the quality of expertise, the results of this investigation revealed that students with different educational backgrounds and studying different diploma‐types, possess a complex of different expertise components.

In relation to the impact of prior knowledge on the acquisition of subject‐oriented knowledge, regression analysis reveals that expertise accounts for 37‐42% of the variance in post‐test scores. The optimization of the instruments used was helpful to differentiate to a better extent the impact of the three different expertise tests.

Since the results of the present study are consistent with the findings of the earlier study in relation to the quality and impact of expertise, more weight can be given to the arguments that can be put forward to support students, in the initial stage of their studies, to cope with the demands of specific domains to be studied.     

Students’ assessment preferences and approaches to learning: can formative assessment make a difference?

The purpose of this paper is to gain insight into the relationships between hands‐on experiences with formative assessment, students’ assessment preferences and their approaches to learning. The sample consisted of 108 university first‐year Bachelor’s students studying criminology. Data were obtained using the Revised two‐factor study process questionnaire (R‐SPQ‐2F) and the Assessment preferences inventory (API). The study shows that differences in assessment preferences are correlated with differences in approach to learning. Students’ preferences for assessment methods with higher‐order thinking tasks are significantly lower after actual experience with a formative assessment. Moreover, students also changed their approaches to learning after hands‐on experience with a formative mode of assessment. Surprisingly, this change evinced a more ‘surface approach’ to learning. Nevertheless, this is in line with other recent research findings. The paper ends with some possible explanations, and new directions for research are proposed.     

The Learning Intention of Low-Qualified Employees: A Key for Participation in Lifelong Learning and Continuous Training

In our continuously changing society, a need for updating one’s skills and knowledge puts pressure on safeguarding the labour market position of low-qualified employees. However, prior research and official statistics show that employees with a lower level of education tend to participate less in training than highly-educated individuals. This limited participation is associated with employers offering fewer opportunities to low-qualified employees, but also with the fact that low-qualified employees themselves might be less willing to participate. In other words, their learning intentions are assumed to be weaker and more restricted than the learning intentions of highly-educated employees. The article reports on a quantitative survey research on the learning intentions of 406 low-qualified employees. The results showed that employees who participated in formal job-related learning activities during the last 5 years had a stronger learning intention than those who did not. Next, the results of the stepwise regression showed that self-directedness, financial benefits, self-efficacy, and autonomy were significant positive predictors of the learning intentions of low-qualified employees. Also, the limited number of possibilities or opportunities to learn was not significant. The results indicated that a learning intention can lead towards the participation in learning activities, but participation is not merely initiated by offering opportunities for learning. Organisational aspects such as job autonomy and financial benefits can stimulate the learning intention of an employee. Finally, regarding the socio-demographic variables, only limited differences were found. In short, employees with no educational qualifications and a full-time contract had the lowest intention to learn.     

An inventory of peer assessment diversity

Since Topping published his literature review on peer assessment in 1998 Topping, K. 1998. Peer assessment between students in colleges and universities. Review of Educational Research, 68: 249–76. [Crossref], [Web of Science ®] [Google Scholar], the number of studies on this subject has doubled, if not tripled. However, along with this expansion, the diversity of peer assessment applications increased equally fast. Based on recent literature, this contribution focuses specifically on the diversity that has come to exist in order to update Topping's typology, adding eight variables, extending eight others with extra sub‐dimensions, and including the implementation factors. Five original variables were absorbed into larger entities, leaving 20 variables which were finally grouped into five clusters. For teachers or advisors, this inventory may be of interest as a source of inspiration or as a checklist of important decisions to make when working with peer evaluation. For researchers, it may be a guide towards covering the full scope of particularities when introducing their peer assessment design. Moreover, the framework developed in this paper might relieve the possible confusion originating from the use of a single term to cover a multitude of sometimes incompatible practices.     

Validation of the SenseWear Armband in different ambient temperatures

This study examines the validity of the SenseWear Armband in different temperatures using the old (SenseWear v2.2) and newest version of the algorithm (SenseWear v5.2) against indirect calorimetry (IC). Thirty-nine male and female students (21.1 ± 1.41 years) completed an exercise trial in 19°C, 26°C and 33°C consisting of 5 min standing followed by alternating walking/running at 35% and 65% of their maximal oxygen uptake. The accuracy of the algorithms was evaluated by comparing estimated energy expenditure (EE) to IC using a mixed-model design. No difference was reported in EE between the different temperatures for IC. Both algorithms estimated EE significantly higher when exercising at high intensity in 33°C compared to 19°C. Compared to IC, SenseWear v2.2 accurately estimated EE during standing and light intensity exercise but underestimated EE when exercising in a hot environment and at high intensity. SenseWear v5.2 showed a difference when exercising at high intensity in thermoneutral and warm conditions. The new algorithm improved EE estimation in hot environments and at high intensity compared to the old version. However, given the inherent inaccuracy of the EE estimates of SenseWear, greater weight should be given to direct monitor outputs rather than the ability of a monitor to estimate EE precisely.     

Identifying configurations of perceived teacher autonomy support and structure: Associations with self-regulated learning,motivation and problem behavior

Grounded in self-determination theory, the aim of this study was (a) to examine naturally occurring configurations of perceived teacher autonomy support and clear expectations (i.e., a central aspect of teacher structure), and (b) to investigate associations with academic motivation, self-regulated learning, and problem behavior. Based on person-centered analyses in a sample of high school students (N = 1036), four different perceived teaching configurations emerged: high autonomy support – clear expectations, low autonomy support – vague expectations, high autonomy support, and clear expectations. The teaching configuration characterized by perceived autonomy support and clear expectations was related to the most positive pattern of outcomes, whereas the opposing teaching configuration related to the most negative pattern of outcomes. The two remaining groups fell in between. The discussion focuses on the compatibility of teacher autonomy support and teacher structure.     

Die Körperzusammensetzung von Hobbygamern im Vergleich zu deutschlandweit erhobenen Referenzdaten

About two thirds of adults in Germany are overweight or obese. While an increase in the consumption of high-calorie food is considered the main cause, the influence of various forms of sedentary activities is still controversially discussed. The aim of the present study is to compare the body composition of hobby gamers with reference data collected throughout Germany and to examine the effects of intensive use of computer games (gaming) on body composition. A total of 68 male participants of a computer game event aged 18–46 years (27.9 years; 180.1?cm; 83.5?kg; BMI 25.7) were examined for fat mass, body cell mass, extracellular mass, body water and phase angle using bioelectrical impedance analysis (BIA, Nutriguard MS type, data input). Ten test persons were retested by means of segmental 8?electrode BIA after a 24?h interval during their visit to the event. As a reference sample, data from 278 male adults of the same age (27.9 years, 179.4?cm; 78.8?kg; BMI 24.5) were collected in 168 locations throughout Germany. The hobby gamers reported on average 37.1?h screen media usage per week. Compared to the reference sample, they showed a slightly higher body cell mass index (p?<?0.01, T?=?4.07), but no differences in fat mass index (p?=?0.96, T?=?0.05) and phase angle (p?=?0.90, T?=?0.12). A significant increase in body water (T₀: 48.2?l, T₀₊₂₄?_h: 49.3?l; p?=?0.04, T?=?2.39) and decrease in the phase angle of the lower extremities (T₀:?7.40, T₀₊₂₄?_h: ?6.85; p?<?0.01, T?=?5.40) was observed in the 24?h retest. Compared to the reference data collected throughout Germany, hobby gamers show no differences in health-relevant parameters of body composition. Nevertheless, after intensive gaming, a short-term increase in the amount of extracellular water in the lower extremities was found. Due to these disturbances in the water balance, the consequent execution of movement breaks during gaming is important.     

Students’ experiences with contrasting learning environments: The added value of students’ perceptions

This study investigated the effects of two contrasting learning environments on students’ course experiences: a lecture-based setting to a student-activating teaching environment. In addition, the evaluative treatment involved five research conditions that went together with one of four assessment modes, namely, portfolio, case-based, peer assessment, and multiple-choice testing. Data (N = 608) were collected using the Course Experience Questionnaire. Results showed that the instructional intervention (i.e. lectures versus student-activating treatment) influenced students’ course experiences, but in the opposite direction to that expected. In declining order, the following scales (5 out of 7) revealed statistically significant differences: Clear Goals and Standards; the General scale; Appropriate Workload; Good Teaching; and Independence. Moreover, when the assessment mode was considered, also the Appropriate Assessment scale demonstrated significant differences between the five research conditions. Moreover, the same teaching/learning environments led to diverse students’ perceptions. While the perceptions of lecture-taught students were focused and concordantly positive, students’ course experiences with student-activating methods were widely varied and both extremely positive and negative opinions were present. Students’ arguments in favour of the activating setting were the variety of teaching methods, the challenging and active nature of the assignments and the joys of collaborative work in teams, whereas students expressed dissatisfaction with the perceived lack of learning gains, the associated time pressure and workloads, and the (exclusive) use of collaborative assignments and related group difficulties.     

Quality standards for new modes modes of assessment. An exploratory study of the consequential validity of the OverAll Test

During the past decade, due to societal developments, methods of instruction as well as the assessment of students’ performances have changed to an important considerable extent. Two of the elements of this change are the accents on cognitive competencies such as problem solving and on learning in an authentic context. In conjunction with the development of such learning methods, new modes of assessment were implemented. It was expected that this change would have positive feedback effects on learning and teaching. These feedback effects are the central issue of this article. They are discussed in terms of the experiences of the Maastricht School of Economics and Business Administration. This school places the analysis of authentic problems at the core of the curriculum, including the learning process as well as the assessment system. The OverAll Test, a case-based assessment instrument aiming to assess problem solving skills, was implemented as part of this. Different quality issues related to the OverAll Test have been evaluated. This article presents the results of one of the four validity studies conducted; an exploratory study of the consequential validity of the OverAll Test. It starts with the an outline of the main features of the new modes of assessment and the OverAll test as an example. There is then a discussed discussion of effectively the OverAll test fits these features as well as the goals and characteristics of problem-based learning. The study of the consequential validity of the OverAll Test is then described in depth. The results of the survey, as well as the results of the semi-structured interviews with staff and students, indicate a friction between the intended characteristics of the learning and assessment environment and the practice of instruction and assessment.
