The influence of college students' epistemological style on selected problem-solving processes

Given the paucity of data supporting college students' epistemological style as an educationally relevant construct, we examined the degree to which individual differences in this style were predictive of various cognitive processing activities adopted to several problem-solving tasks. Twenty-two college subjects from each of three different epistemological groups—dualistic, multiplistic, and relativistic—were randomly selected to complete both a syllogism and Ink Blot problem-solving task. The results showed that the three epistemological groups reliably differed in how they mentally organized the ink blot stimuli, but not the syllogism problems. The findings are discussed as supporting the notion that the epistemology construct is an educationally salient source of individual differences, especially when performance tasks are ambiguous and ill-defined.     

Race and Color: Two Sides of One Story? Development of Biases in Categorical Perception

Categorical perception is a phenomenon that leads people to group stimuli into categories instead of perceiving their natural continua. This article reviews the literature of two biases connected with categorical perception: categorical color perception and the other‐race effect. Although these two phenomena concern distant targets (colors and faces) and imply different biases (one attentional, one mnemonic), they share at least three commonalities. First, they both involve the chunking of continuous dimensions into categories. Second, adult categories are shaped by cultural processes. Third, infants' discrimination performance seems universal and guided by perception. In this article, it is proposed to look for a common developmental mechanism that clarifies the shift from a perceptual to a sociocognitive knowledge of the environment. New perspectives are discussed.     

School motivation: A comparison between Kenya and Italy

The authors compare school motivation in Kenya and Italy, two countries that differ in terms of socioeconomic conditions, structure of the school system, and access to education. Free primary education is indeed a recent attainment for Kenyan students. The participants, 449 Kenyan and 480 Italian students, 9–14 years old and attending Grades 4–8, were asked to complete a questionnaire about learning motivation. A factor analysis revealed that school motivation can be described by five dimensions in both contexts: intrinsic motivation, extrinsic motivation, academic self-concept, causal attribution, and amotivation. Differences between countries and lower (Grades 4–5) and higher (Grades 6–8) grades emerged: intrinsic motivation, extrinsic motivation, and academic self-concept were found to be higher in Kenyan than in Italian students, whereas amotivation was lower. Moreover, only Italian students showed less intrinsic motivation and more amotivation in higher grades than in the lower ones.     

How does innovative continuous professional development (CPD) operate in the ECEC sector? Insights from a cross-analysis of cases in Denmark,Italy and Poland

This article offers insights into what characterises innovative continuous professional development (CPD) in the field of early childhood education and care (ECEC) by analysing similarities and differences from case studies of exemplary approaches to innovative CPD in Denmark, Italy and Poland. The comparative analysis focuses on four features that are particularly relevant for innovation in CPD in the field of ECEC: the social dimension of innovation as a strengthening component; the benefit of dynamic learning processes aimed at integrating theory and practice; the role of key figures in the quality of CPD; and measurements of CPD impact, outcomes and sustainability. This analysis sheds light on the effects of dynamic factors (e.g., regular team-based reflection sessions based on documentation and observation), the importance of work conditions (e.g., contractual obligations to provide time for reflection), the critical role of pedagogical leaders (coordinators, principals and head teachers, supervisors), the importance of inter-organisational networking at a local level and the facilitating role of collaboration with research institutes.     

The missing base molecules in atmospheric acid–base nucleation

Transformation of low-volatility gaseous precursors to new particles affects aerosol number concentration, cloud formation and hence the climate. The clustering of acid and base molecules is a major mechanism driving fast nucleation and initial growth of new particles in the atmosphere. However, the acid–base cluster composition, measured using state-of-the-art mass spectrometers, cannot explain the measured high formation rate of new particles. Here we present strong evidence for the existence of base molecules such as amines in the smallest atmospheric sulfuric acid clusters prior to their detection by mass spectrometers. We demonstrate that forming (H₂SO₄)₁(amine)₁ is the rate-limiting step in atmospheric H₂SO₄-amine nucleation and the uptake of (H₂SO₄)₁(amine)₁ is a major pathway for the initial growth of H₂SO₄ clusters. The proposed mechanism is very consistent with measured new particle formation in urban Beijing, in which dimethylamine is the key base for H₂SO₄ nucleation while other bases such as ammonia may contribute to the growth of larger clusters. Our findings further underline the fact that strong amines, even at low concentrations and when undetected in the smallest clusters, can be crucial to particle formation in the planetary boundary layer.     

Engaging in science practices in classrooms predicts increases in undergraduates' STEM motivation,identity, and achievement: A short-term longitudinal study

Our short-term longitudinal study explored undergraduate students' experiences with performing authentic science practices in the classroom in relation to their science achievement and course grades. In addition, classroom experiences (felt recognition as a scientist and perceived classroom climate) and changes over a 10-week academic term in STEM (science, technology, engineering, and mathematics) identity and motivation were tested as mediators. The sample comprised 1,079 undergraduate students from introductory biology classrooms (65.4% women, 37.6% Asian, 30.2% White, 25.1% Latinx). Using structural equation modeling (SEM), our hypothesized model was confirmed while controlling for class size and GPA. Performing science practices (e.g., hypothesizing or explaining results) positively predicted students' felt recognition as a scientist; and felt recognition positively predicted perceived classroom climate. In turn, felt recognition and classroom climate predicted increases over time in students' STEM motivation (expectancy-value beliefs), STEM identity, and STEM career aspirations. Finally, these factors predicted students' course grade. Both recognition as a scientist and positive classroom climate were more strongly related to outcomes among underrepresented minority (URM) students. Findings have implications for why large-format courses that emphasize opportunities for students to learn science practices are related to positive STEM outcomes, as well as why they may prove especially helpful for URM students. Practical implications include the importance of recognition as a scientist from professors, teaching assistants, and classmates in addition to curriculum that engages students in the authentic practices of science.     

Balancing academic and professional pedagogies: a comparative study of two accounting departments in South Africa and the UK

The paper adds to extant professional education literature by reflecting on apparent differences in pedagogy of similar professional programmes of study, allowing deeper insight into the unique strand of higher education influenced by the professions. A comparative international case study approach is adopted of an interpretive qualitative nature regarding curricular, teaching and learning and assessment strategies of an accounting department in South Africa (SA) and one in the UK. Findings point to significant differences in curriculum and assessment but less so in teaching and learning approaches. One department endeavoured to find a balance between vocational and academic activities, whilst the other favoured the former being inconsistent with both its governmental and institutional governing bodies. Explanations offered include differing strengths of coercive, competitive, mimetic and normative influence     

Seeking resilience and sustainability: outdoor education in Singapore

Outdoor education is not a universal value. Rather, outdoor education's contributions need to be grounded in time, place and culture. In this paper we describe the historical and cultural milieu that has enabled the emergence of outdoor education in Singapore and report on exploratory survey research into Singaporean teachers' conceptions of outdoor education. We compare the reported outcomes of outdoor education in Singapore to similar studies from Australia and New Zealand. Further focus group research is then used to develop a vision for outdoor education in Singapore. In so doing we aim to illustrate, and celebrate, how culturally-specific circumstances must be considered in both interpreting and conceptualizing outdoor education. We conclude that while personal development outcomes are important for Singaporean outdoor educators, these are developed more for the benefits of society and the State. The future role of outdoor education in Singapore will most probably continue to be linked to ongoing and emerging social and cultural imperatives such as harmony among diverse religious groups and environmental consequences of climate change.
