Secondary School Students’ Errors in the Translation of Algebraic Statements

In this article, we present the results of a research study that explores secondary students’ capacity to perform translations of algebraic statements between the verbal and symbolic representation systems through the lens of errors. We classify and compare the errors made by 2 groups of students: 1 at the beginning of their studies in school algebra and another 1 completing their studies on algebra in compulsory education. This comparison allows us to detect errors which require specific attention in instruction due to its persistence and to identify errors that disappear as students advance in their study of algebra. The results and conclusions have a pedagogic value to inform instruction and also lead to backed conjectures and research questions to push forward research on student’s translation capacity and students’ knowledge of algebraic symbolism.     

Some Learning Problems Concerning the Use of Symbolic Language in Physics

This paper aims to draw the attention of teachers of basic university physics courses towards students' problems concerning the interpretation of the symbolic language used in the discipline. Specific difficulties found in the first course of physics, related to different kinds of statements expressed in mathematical language, are pointed out and analysed, and some suggestions are made to cope with them during instruction. It could be concluded that teachers may need only to reflect and comment on the virtues of making explicit the semantic and syntactic aspects of formal languages as they teach physics.     

Reading prosody development in Spanish children

Reading prosody is considered one of the essential markers of reading fluency, alongside accuracy and speed. The aim of our study was to investigate how development of reading prosody in Spanish children varies with sentence type and length. We compared primary school children from the third and fifth grades with an adult sample. Participants were recorded reading aloud a narrative text including short and long declarative, exclamatory and interrogative sentences. Recordings were analysed using Praat software to measure several prosodic features (i.e., pauses, duration, pitch and intensity). We found that third-grade children had not yet developed an adult-like prosody: they made more pauses, had a flatter melodic contour and had difficulty anticipating sentence structure. Fifth-graders displayed some features of adult prosody. Both length and type of sentence influenced the expressiveness of reading in the three groups. We conclude that reading expressiveness is closely related to reading experience and develops in a similar way to decoding and reading speed.     

The Spanish Version of the Empathy Questionnaire (EmQue): Evidence for Longitudinal Measurement Invariance and Relationship With Emotional Regulation

Research Findings: Empathy, or the ability to understand what others are thinking or feeling, can be observed in early developmental stages. The purpose of this study was to validate the Spanish version of the Empathy Questionnaire (EmQue) and examine its longitudinal measurement invariance (LMI) at 2 time points. Parents of 103 children completed the EmQue when their children were 3 (M = 41.76) and 4 (M = 51.65) years old. Confirmatory factor analyses revealed that Grazzani, Ornaghi, Pepe, Brazzelli and Rieffe’s (2016) 3-factor model of emotional contagion (EC), attention to others’ feelings, and prosocial actions (PA) presented the best fit indices at both time points (Time 1: CFI = .931, TLI = .914, and RMSEA = .070; Time 2: CFI = .941, TLI = .935, and RMSEA = .064). Moreover, preliminary evidence was obtained for the LMI of this model. PA scores increased over time. Score reliability ranged from .60 (EC) to .83 (PA). Positive correlations were found between PA and emotional regulation at each time point and across time.Practice or Policy: The great relevance of empathy and prosocial behavior in academic achievement and psychological adjustment justifies the development of reliable instruments to evaluate these constructs from early ages.     

Electromyographic analysis of lower limb muscles during the golf swing performed with three different clubs

The aim of this study was to describe and compare the EMG patterns of select lower limb muscles throughout the golf swing, performed with three different clubs, in non-elite middle-aged players. Fourteen golfers performed eight swings each using, in random order, a pitching wedge, 7-iron and 4-iron. Surface electromyography (EMG) was recorded bilaterally from lower limb muscles: tibialis anterior, peroneus longus, gastrocnemius medialis, gastrocnemius lateralis, biceps femoris, semitendinosus, gluteus maximus, vastus medialis, rectus femoris and vastus lateralis. Three-dimensional high-speed video analysis was used to determine the golf swing phases. Results showed that, in average handicap golfers, the highest muscle activation levels occurred during the Forward Swing Phase, with the right semitendinosus and the right biceps femoris muscles producing the highest mean activation levels relative to maximal electromyography (70–76% and 68–73% EMG_MAX, respectively). Significant differences between the pitching wedge and the 4-iron club were found in the activation level of the left semitendinosus, right tibialis anterior, right peroneus longus, right vastus medialis, right rectus femuris and right gastrocnemius muscles. The lower limb muscles showed, in most cases and phases, higher mean values of activation on electromyography when golfers performed shots with a 4-iron club.     

Understanding inclusion support systems: three inspiring experiences / Comprendiendo los sistemas de apoyo para la inclusión: tres experiencias inspiradoras

This article presents the findings of an empirical study that aimed to gain an in-depth understanding of how inclusive support systems are configured. A qualitative case study approach was used to explore the trajectories, shared beliefs and daily practices that shape the dynamics of three educational centres recognized by external assessors for their inclusive policies and attention to diversity. The analysis carried out enabled the identification of patterns of worldviews and practices that underpin the development of sustainable inclusive school proposals, as well as an understanding of the complex interrelationship between context, resources, opportunities, threats and teaching approaches that define particular dynamics. The findings obtained help to illustrate and provide inspiration for other schools committed to defending the basic rights of all children and young people, as well as designers of educational policies and programmes.
