Learning to teach STEM disciplines in higher education: a critical review of the literature

ABSTRACT

Enrolments in STEM disciplines at universities are increasing globally, attributed to the greater life opportunities open to students as a result of a STEM education. But while institutional access to STEM programmes is widening, the retention and success of STEM undergraduate students remains a challenge. Pedagogies that support student success are well known; what we know less about is how university teachers acquire pedagogical competence. This is the focus of this critical review of the literature that offers a theorised critique of educational development in STEM contexts. We studied the research literature with a view to uncovering the principles that inform professional development in STEM disciplines and fields. The key finding of this critical review is how little focus there is on the STEM disciplines. The majority of studies reviewed did not address the key issue of what makes the STEM disciplines difficult to learn and challenging to teach.     

Effect of Intermittent Kangaroo Mother Care on Weight Gain of Low Birth Weight Neonates With Delayed Weight Gain

Objective: To evaluate intermittent Kangaroo Mother Care (KMC) with additional opportunities to breastfeed on weight gain of low birth weight (LBW) neonates with delayed weight gain. Methods: 40 LBW neonates were followed to see whether KMC with additional opportunities to breastfeed improved weight gain. Results: In the KMC group, the mean age of regaining birth weight was significantly less (15.68 vs. 24.56 days) and the average daily weight gain was significantly higher (22.09 vs. 10.39 g, p < .001) than controls. Conclusion: KMC with additional opportunities to breastfeed was found to be an effective intervention for LBWs with delayed weight gain and should be considered to be an effective strategy.     

Letters to the Editor as a Forum for public deliberation: modes of publicity and democratic debate

–This paper traces, through in-depth interviews with San Francisco Bay letters editors, the criteria editors use to select letters, and examines how these criteria contribute to constructing the public by privileging certain forms of expression, and suppressing others. In constructing a theoretical framework, the paper draws on political philosophy to distinguish between three prevalent modes of publicity: Exhibitionist publicity, focused on the display of individual greatness; dialogist publicity, emphasizing democratic dialogue between groups and individuals; and activist publicity, which entails the confrontation between groups that seek to advance political goals. With this framework in mind, it is argued that editors' policies on letters selection bring about two orientations toward public debate: First, editors privilege individual expression over the expression of activist groups. Secondly, editors prefer the emotionally charged stories of individuals. These orientations challenge the ideals of rationality and deliberation that underlie the practice of dialogist publicity, as well as the contestatory nature of activist publicity. Instead, editors' principles favor an exhibitionist publicity. The paper explores the political philosophical implications of this orientation, arguing that while it does not square with democratic ideals, we must be cognizant of how such display can bring about social solidarity.     

Political distrust in Hong Kong: News media use and political beliefs regarding the 1997 transition

As Hong Kong prepares for a political transition in 1997, neither the existing colonial British government nor the impending People's Republic of China (PRC) has established a strong historical foundation for political trust within the territory. In this study, we examine the level of distrust towards the existing and future political regimes, as well as attitudes towards Hong Kong's future. Based on a representative telephone survey of Hong Kong residents (N = 512), we find a high degree of political distrust among respondents, particularly towards the PRC administration. Although initial bivariate analyses establish some association between distrust and media exposure, channel preference, and demographic variables, further multivariate analyses suggest that many of these factors are highly interrelated. One central finding is that among men and those with middle to high socio‐economic status, television news exposure is associated with trust in the PRC. Conversely, women and younger people tend to distrust the PRC, regardless of their news exposure.     

Language and Mathematical Performance: a Comparison of Lower Secondary School Students with Different Level of Mathematical Skills

This study investigated the connection between language (i.e., word comprehension, reading comprehension and spelling skills) and mathematical performance. The sample consisted of grade nine students (N?=?810) in 14 lower secondary schools in the Swedish speaking areas of Finland. Standardized tests for reading and writing skills, and mathematical performance were used. Based on the mathematics test the students were categorized into eight performance groups. Many students had problems in both mathematics and language performance. On the whole data level reading skills were a powerful predictor for math performance, the reading factor explained 52% of the variance in the model. Hence, the reading skills focusing on understanding of the text are important in solving mathematical tasks at the end of compulsory school.     

Influences of family based prerequisites,reading attitude,and self-regulation on reading ability

This study investigated the effect of self-regulated learning, as indicated by academic self-concept, motivation and learning strategies, reading attitude and family based prerequisites on reading ability. Students (n = 4018) in the eighth grade answered the IEA reading literacy test, the self-regulated learning questionnaire and a student questionnaire about their background. The exploratory factor analysis (EFA) revealed that the self-regulated learning questionnaire did not measure the intended three dimensions, but only two: Verbal/General academic self-concept and a new dimension called Goal oriented strategies. Structural Equation Modelling (SEM) with a cross-validation sample was conducted to determine the effects in the final model. The strongest effect on reading ability was from Verbal/General academic self-concept (β = .43 for final and β = .56 for cross-validation model). Gender differences revealed that girls read better on narrative and expository texts, had a more positive reading attitude, and more positive verbal self-concept, whereas boys had a higher academic self-concept (not domain-specific), self-efficacy, control expectation, reported more memorising, elaboration, and instrumental motivation (all differences p < .001).     

Perceived self-efficacy and social anxiety changes in high school students with learning disabilities (LD) during first year of secondary vocational education

This empirical study focused on high school students with a learning disability (LD), particularly adolescents undergoing training in secondary vocational study programmes. A total of 417 1st-year high school students were included in the survey, 105 of whom were LD students. Data on social anxiety and perceived social self-efficacy were collected at the beginning and end of the school year using the Social Self-Efficacy Scale and the LSAA Social Anxiety Scale. The results mostly relate to male students because the sample included 359 boys and 58 girls. In both the initial and final measurements, a significantly lower level of perceived social self-efficacy and a higher level of social anxiety were found in students with special needs compared to their peers. Perceived self-efficacy in LD students decreased significantly during the school year, while changes in social anxiety were not statistically significant. Results could indicate some difficulties in social integration of LD youths in vocational school classes. Thus, it would be desirable for schools to provide a more supportive and efficient learning environment for strengthening social integration of LD students in secondary vocational education.     

Voices from South and North in dialogue: on diversity and education for the future

In this article texts by scholars from South Africa, Sweden and Great Britain are analysed. They contributed as invited speakers to a conference in Sweden in 2009 on changing societies, values, religions and education. Here a South–North dialogue on diversity and the future of education is constructed through the way their conference contributions are presented and analysed. Democracy and gender also appear as crucial themes. Out of the original 12 keynote contributions to the conference a selection is made, meaning that seven of them are focused on. What can be observed is (a) that the contributors from South Africa connect diversity and social justice; (b) that the gender researchers critically discuss the risks of the North imposing its theoretical framework on the South and search for ways out of that and (c) a preoccupation with a renewal of education recognising diversity but also looking for what could come beyond such an emphasis and form a common ground. The article constitutes an example of shared knowledge production where South and North meet. Conditions for that are critically reflected upon methodologically.
