A comparative study on student perceptions of their learning outcomes in undergraduate science degree programmes with differing curriculum models

ABSTRACT

This study investigated students’ perceptions of their graduate learning outcomes including content knowledge, communication, writing, teamwork, quantitative skills, and ethical thinking in two Australian universities. One university has a traditional discipline-orientated curriculum and the other, an interdisciplinary curriculum in the entry semester of first year. The Science Students Skills Inventory asked students (n?=?613) in first and final years to rate their perceptions of the importance of developing graduate learning outcomes within the programme; how much they improved their graduate learning outcomes throughout their undergraduate science programme; how much they saw learning outcomes included in the programme; and how confident they were about their learning outcomes. A framework of progressive curriculum development was adopted to interpret results. Students in the discipline-oriented degree programme reported higher perceptions of scientific content knowledge and ethical thinking while students from the interdisciplinary curriculum indicated higher perceptions of oral communication and teamwork. Implications for curriculum development include ensuring progressive development from first to third years, a need for enhanced focus on scientific ethics, and career opportunities from first year onwards.     

Informal Learning with Technology: The Effects of Self-Constructing Externalizations

ABSTRACT

Especially in the context of technology-enhanced informal learning, it is crucial to understand how to design information sources in such a way that learners are not overwhelmed by the demands of the learning process, but at the same time are engaged in higher order thinking processes. Guidance aids learners in dealing with the demands of a learning process. The authors examined the effects of different levels of guidance provided by an information source. To this end, the effects of a preconstructed externalization are compared to a self-constructed externalization. Thirty-eight students participated in the study. The results revealed no significant differences between the groups with respect to posttest retention. However, performance in application tasks was promoted by the condition associated with a lower level of guidance. This suggests that having learners self-construct an externalization might be a suitable means to elicit learners’ higher order thinking processes in technology-enhanced informal learning.     

The use of heuristics during route planning by expert and novice orienteers

Expert orienteers have reported using two heuristics when planning routes to points in the environment that must be located, known as 'controls'. These heuristics constitute attending to the start first and subsequently planning forward to a given control, and attending to the control first and planning backwards to the start. The aim of this study was to establish which heuristic experts use predominantly and whether novices' use of these heuristics differs from that of experts. Two methods for tracing attention were used while 20 expert and 20 novice orienteers planned routes in the laboratory. The results were used to infer the use of heuristics. The orienteers were also interviewed about planning. We found that, when planning, experts generally attend to the control first and novices to the start first. There was also some evidence that novices work forwards from the start to the control and that experts work backwards from the control to the start. From the interviews, it would appear that experts regard the location of the control as the crux of the problem and prioritize this area during planning. These results have implications for an understanding of expertise and problem-solving in sport.     

Physical activity, nutrition, screen time and sleep associated with body weight and physical condition in young children

The aim of this cross-sectional study was to explore the possible relationship between (un)healthy behaviour and (over)weight and physical condition in families with young children (4–7 years), in a village (30,000 inhabitants) in the eastern part of the Netherlands, close to Germany. It is one of two pilot studies as a precursor of a cross-border project including six Dutch and six German villages, to counteract physical inactivity and possible future metabolic problems. In total, 459 children of five elementary schools and their parents were included. Parents were requested to fill in a questionnaire on the nutritional, physical, sedentary, and sleeping behaviour of their child. Relevant background characteristics were obtained and lifestyle classifications were made. At school, the children's height and weight (body mass index (BMI)) were measured, as well as their physical condition (two tests) and basic motor abilities (four physical exercise tests). The relationship between the standardized BMI z-scores and physical condition test scores, and nutritional, physical, sedentary and sleeping habits was analysed using independent sample t-test, bivariate correlation analysis and multiple regression analysis. Latent class analysis was used to identify clusters of people based on their nutritional, physical and sleep habits. Of the parents, 376 (82?%) were willing to fill out the questionnaire. High birth weight and a high BMI of the mother and/or father correlated with a higher BMI of the child (ρ?=?0.28, p?<?0.001; ρ?=?0.13, p?=?0.016; and ρ?=?0.23, p?<?0.001, respectively). Daily playing outside, eating small cookies (compared with large cookies) and no sleeping problems (no waking up during the night) were related to low BMI levels (no overweight) [ρ?=???0.14, p?=?0.005; ρ?=???0.12, p?=?.020; t(364)?=?1.81, p?=?0.072 (trend), respectively]. Daily playing outside (frequency and duration) and being a member of a sports club were related to positive scores on the physical condition tests [ρ?=?0.20, p?<?0.001; t(365)?=???2.99, p?=?0.003, respectively]. High levels of television (TV) watching and general sleeping problems were related to a less optimal physical condition [ρ?=???0.09, p?=?0.076 (trend); and ρ?=???0.10, p?=?0.059 (trend), respectively]. A latent class analysis revealed three clusters: 46?% of the sample belonged to the ‘healthy group’ concerning nutrition, sedentary lifestyle and TV/personal computer (PC) use; 17?% to the ‘less healthy’ group and 37?% to a group with nutrition and physical activity habits close to the healthy group, but with low conditional probabilities for the sleeping items. Conducting a pilot study before the start of a binational intervention study gives a blueprint for the final questionnaire, and clues for tailored interventions in the schools, as proposed in the approach of ‘Gesunde Kinder in gesunden Kommunen’ (GKGK). The results of a latent class analysis underscore that interventions should exist of a multi-component strategy, focusing on promoting physical activity, healthy nutrition habits and appropriate sleep.     

Organ economy: organ trafficking in Moldova and Israel

Organ trafficking is an illegal means of meeting the shortage of transplants. The activity flourishes for several interacting reasons, such as medical needs, poverty and criminality. Other factors are fundamental conceptual structures such as the dream of the regenerative body as well as the view of the body as an object of utility and an object of value. The article aims to go behind the normative discussions that usually surround organ trafficking. Why this is happening, and what the societal consequences are, is examined through ethnographic fieldwork. The focus is on the shadow economies that govern existence and in which people, goods, weapons, money, bodies, etc. constitute components of the global market.     

Productivity effects of basic research in low-tech and high-tech industries

R&D encompasses plenty of activities which are usually summarized under the terms of basic research, applied research and development. Although basic research is often associated with low appropriability it provides the fundamental basis for subsequent applied research and development. Especially in the high-tech sector basic research capabilities are an essential component for a firm's success. We use firm-level panel data stemming from Belgian R&D surveys and apply a production function approach which shows that basic research exhibits a premium on a firm's output when compared to applied research and development. When we split the sample into high-tech and low-tech companies, we find a large premium of basic research for firms in high-tech industries, but no premium in low-tech sectors.     

Word length and word frequency affect eye movements in dyslexic children reading in a regular (German) orthography

We combined independently the word length and word frequency to examine if the difficulty of reading material affects eye movements in readers of German, which has high orthographic regularity, comparing the outcome with previous findings available in other languages. Sixteen carefully selected German-speaking dyslexic children (mean age, 9.5 years) and 16 age-matched controls read aloud four lists, each comprising ten unrelated words. The lists varied orthogonally in word length and word frequency: high-frequency, short; high-frequency, long; low-frequency, short; low-frequency, long. Eye movements were measured using a scanning laser ophthalmoscope (SLO). In dyslexic children, fixation durations and the number of saccades increased both with word length and word frequency. The percentage of regressions was only increased for low-frequency words. Most of these effects were qualitatively similar in the two groups, but stronger in dyslexic children, pointing to a deficient higher-level word processing, especially phonological deficit. The results indicate that reading eye movements in German children are modulated by the degree of difficulty, and orthographic regularity of the language can determine the nature of modulation. The findings suggest that, similar to Italian but unlike English readers, German children prefer indirect sub-lexical strategy of grapheme-phoneme conversion.     

The Loss of Biodiversity as a Challenge for Sustainable Development: How Do Pupils in Chile and Germany Perceive Resource Dilemmas?

The topic of biodiversity is of high value for education for sustainable development as it reflects the interaction of ecological, economic and social issues particularly well. Especially in so-called biodiversity hotspots, among them Chile, natural resources are often depleted for economic interest which, in many cases, is required income. Therefore, economic and social aspects must be considered in order to fully understand biodiversity loss. Being such an important issue, it is surprising that little is known thus far about learning prerequisites concerning biodiversity. This paper presents a qualitative interview study that investigated 16 to 18-year-old Chilean and German learners’ perception of biodiversity and its loss (n?=?24). Firstly, the pupils’ cognitive frameworks were analysed. Secondly, subjective theories about biodiversity loss due to resource dilemmas were explored. Three subjective theories that emerged from the data reflected the notion that most pupils focused on either ecological or economic aspects of biodiversity loss. Pupils who concentrated on ecological aspects often referred to incorrect ecological facts. Moreover, these pupils showed difficulties in developing empathy and solidarity with impoverished people, who depend economically on plants in a resource dilemma. A smaller group of pupils succeeded in integrating the ecological, economic, and social aspects. Regarding the two samples, Chilean pupils seemed to have greater difficulties in recognising the social aspects of biodiversity loss, while German pupils were largely unaware of biodiversity loss on a local level. Implications for biodiversity education and future research will be outlined and discussed.     

Brauchen mehrsprachige Jugendliche eine andere fach- und sprachintegrierte Förderung als einsprachige?

Which kinds of content- and language-integrated interventions can better support mathematical learning, depending on students’ language background, as measured by communication on the discourse level or additional lexical training on the word level? A control trial compared interventions with two different materials (discursive versus lexical-discursive, each 5 × 90?min.) with respect to the dependent variable of conceptual and procedural knowledge for fractions. The effects are investigated differentially for four language groups: monolinguals versus bilinguals, each with higher versus lower German language proficiency (n = 343). For both interventions, the ANOVA shows an increase of mathematical knowledge for the experimental group, which is significantly higher than for the control group, but no significant difference between the interventions. The intervention with lexical-discursive materials led to a slightly higher increase of knowledge in the post test, but the discursive intervention was superior in the follow up test. Monolingual and multilingual students had similar patterns of growth without differential pattern. However, the proficient monolingual students tend to profit more from the interventions, especially from the lexical-discursive intervention.
