Enhancing the Student Experiment Experience: Visible Scientific Inquiry Through a Virtual Chemistry Laboratory

Practical work is often noted as a core reason many students take on science in secondary schools (high schools). However, there are inherent difficulties associated with classroom practical work that militate against scientific inquiry, an approach espoused by many science educators. The use of interactive simulations to facilitate student inquiry has emerged as a complement to practical work. This study presents case studies of four science teachers using a virtual chemistry laboratory (VCL) with their students in an explicitly guided inquiry manner. Research tools included the use of the Inquiry Science Implementation Scale in a ‘talk-aloud’ manner, Reformed Teaching Observation Protocol for video observations, and teacher interviews. The findings suggest key aspects of practical work that hinder teachers in adequately supporting inquiry and highlight where a VCL can overcome many of these difficulties. The findings also indicate considerations in using the VCL in its own right.     

A longitudinal investigation of direct and indirect links between reading skills in kindergarten and reading comprehension in tenth grade

In this study, researchers examined the extent to which several fundamental measures of reading proficiency from kindergarten students (N = 3180) were linked to reading comprehension in tenth grade while controlling for third grade vocabulary and oral reading fluency. Analyses tested the direct and indirect relations between and among kindergarten, third grade, and tenth grade measures. Results showed significant direct effects from kindergarten nonsense word fluency and letter naming fluency to tenth grade reading comprehension, along with significant indirect effects of kindergarten nonsense word fluency and vocabulary to tenth grade reading comprehension. Findings suggest that fundamental precursors maintain strong impact upon reading comprehension into the secondary school years. These findings are discussed along with implications for interventions and ideas for future research.     

Development of oral reading fluency in children with speech or language impairments: a growth curve analysis

This longitudinal study used piece-wise growth curve analyses to examine growth patterns in oral reading fluency for 1,991 students with speech impairments (SI) or language impairments (LI) from first through third grade. The main finding of this study was that a diagnosis of SI or LI can have a detrimental and persistent effect on early reading skills. Results indicated differences between subgroups in growth trajectories that were evident in first grade. A large proportion of students with SI or LI did not meet grade-level reading fluency benchmarks. Overall students with SI showed better performance than students with LI. Reading fluency performance was negatively related to the persistence of the SI or LI; the lowest performing students were those originally identified with SI or LI whose diagnosis changed to a learning disability. The results underscore the need to identify, monitor, and address reading fluency difficulties early among students with SI or LI.     

Measuring in-service teacher self-efficacy for teaching computational thinking: development and validation of the T-STEM CT

Education and Information Technologies - Despite a growing recognition that K-12 teachers should be prepared to teach students computational thinking (CT) skills across disciplines, there is a lack...     

Using matrix norms to estimate the direction of arrival of planar waves on an ULA

SEAD method estimates the direction-of-arrival angles on an uniform linear array based on the difference between the two largest singular values, what is called differential spectrum. Although it presented an outstanding performance, the ability to indicate the source positions was not elucidated yet. Inspired by the differential spectrum formulation we derived a total differential spectrum and found out that the matrix norm induced by the vector 2-norm of a modified spatial covariance matrix can be used to estimate the direction-of-arrival of multiple plane waves. Indeed we show that matrix norms are estimators and we propose their use instead of the singular value decomposition in SEAD-based methods. We present a general mathematical expression in order to explicit the operating principles of the proposed methods. Consequently, we were able to explain how the relation between the arriving and the search angles produces the larger peaks on the differential spectrum. To evaluate the important role played by matrix norms, a thousand experiments were carried out. They showed that the proposed approach proved to be as accurate as the previous SEAD-based methods, while providing a significant reduction on runtime. It also outperformed well-established methods like MODEX regarding the estimation error.     

How do teachers perceive cheating students? Beliefs about cues to deception and detection accuracy in the educational field

The present study explores how well teacher trainees can detect liars. Moreover, a new method was applied to investigate beliefs that teacher trainees hold about liars. The results indicate that, overall, teacher trainees were not better than chance in detecting true and invented stories. Generally, participants reported to have used only a few cues for their credibility judgment, where most of these self-reported cues are stereotypical and invalid deception cues (e.g., gaze aversion). Further analyses with a Brunswikian lens model showed that the self-reported cues were good predictors of their credibility judgment but only poorly predictive for the objective truth/lie status of the statement. Practical implications of the results are discussed.     

Phonological recoding as a universal process?

A phonological confusion task was employed to explore whether or not beginning readers of Chinese activate phonological codes while reading Chinese characters. Twenty first graders and twenty third graders read phonologically similar and dissimilar character strings. Following the presentation of each string, they were required to identify the characters from among a set of recognition items. Three major findings indicated that subjects used phonological codes while reading Chinese characters: (1) Subjects recognized fewer phonologically similar characters than phonologically dissimilar ones; (2) The phonological confusion effect varied with degree of phonological similarity among the characters read. Characters having the same rhyme and same tone (SRST) were recognized less accurately than characters of the same rhyme but different tones (SRDT), which in turn were recognized less accurately than characters of different rhymes and different tones (DRDT); (3) Silent reading and oral reading resulted in similar patterns of phonological confusion, indicating that similar codes were activated during the two reading conditions.     

The female fish is more responsive: gender moderates the BFLPE in the domain of science

Academic self-concept is positively related to individual achievement but negatively related to class- or school-average achievement: the big-fish–little-pond effect (BFLPE). This contrast effect results from social comparison processes. The BFLPE is known to be long-lasting, universal and robust. However, there is little evidence regarding its generalisability across genders. Females, as opposed to males, feel more attached to their peers and compare themselves more often. Thus, it was hypothesised that the BFLPE is larger for females. This was investigated with a focus on science self-concept in a German sample from an extension of the Programme for International Student Assessment 2006 study (N?=?35,015) using recent advances in multilevel modelling. Replicating previous findings, females reported lower self-concepts while controlling for achievement. Additionally, the BFLPE was replicated. However, its effect size was substantially larger for females (?.41) compared to males (?.30). The implications of the results are discussed in light of women’s persisting underrepresentation in science, technology, engineering and mathematics fields.     

Migration,disability and education: reflections from a special school in the east of England

Studies of migrant pupils in schools have paid little attention to people with special educational needs and/or disabilities, reflecting a broader normative ableism of existing scholarship. This article, based on a case study of a special school in the east of England, explores the perspectives of staff and new migrants on their experiences. The article exposes how migrant families’ interactions with schools were shaped both by their previous migration histories and current broader processes of ‘integration’. Teachers were empathetic and supportive, but it was the extended remit of the work of migrant and minority staff (including translation and wider caring roles) that proved particularly vital for families. We employ an intersectional approach to interpret these encounters, exposing the tensions and dilemmas arising. Further research is needed to develop understanding and critical engagement with the challenges facing these families, arising from the specific intersections of disability, migration, social class and gender.     

Determinants of Impact: Towards a Better Understanding of Encounters with the Arts

The article argues that current methods for assessing the impact of the arts are largely based on a fragmented and incomplete understanding of the cognitive, psychological and socio-cultural dynamics that govern the aesthetic experience. It postulates that a better grasp of the interaction between the individual and the work of art is the necessary foundation for a genuine understanding of how the arts can affect people. Through a critique of philosophical and empirical attempts to capture the main features of the aesthetic encounter, the article draws attention to the gaps in our current understanding of the responses to art. It proposes a classification and exploration of the factors—social, cultural and psychological—that contribute to shaping the aesthetic experience, thus determining the possibility of impact. The ‘determinants of impact’ identified are distinguished into three groups: those that are inherent to the individual who interacts with the artwork; those that are inherent to the artwork; and ‘environmental factors’, which are extrinsic to both the individual and the artwork. The article concludes that any meaningful attempt to assess the impact of the arts would need to take these ‘determinants of impact’ into account, in order to capture the multidimensional and subjective nature of the aesthetic experience.
