A negative correlation between mathematics performance and mathematics anxiety (MA) has been identified in students of varying ages. However, little is known as to whether this correlation diminishes when environmental factors are incorporated as moderator variables. Specifically, the effect of home numeracy activities (HNA) and parental MA on students’ performance-MA relationship has received little attention. Furthermore, there have been no studies that consider HNA frequency as reported by the children themselves. A sample of 311 Chilean second graders and their parents participated in the present study. We examined whether HNA frequency moderates the performance-MA relationship and whether this moderation is in turn moderated by parent MA. Results showed that the frequency of HNA strengthened or diminished the negative correlation between performance and MA as a function of parent MA. In the case of parents with low MA, regardless of HNA frequency, child mathematics performance was negatively associated with child MA. However, in the case of math-anxious parents that interacted frequently with their children, there was no association between child MA and math achievement. More broadly, the present study suggests that mathematics-related family dynamics and parents’ emotions are key to understanding the relationship between performance and MA in early development.

En esta investigación se indagó acerca de las actitudes hacia la química de 444 estudian-tes de secundaria chilenos, empleando un método mixto de diseño secuencial explicativo. Los resul-tados descriptivos revelaron actitudes relativamente bajas en las dos dimensiones analizadas, cognitiva y afectiva, aunque levemente superiores en la última. Los resultados inferenciales mostraron que el nivel escolar y el rendimiento académico afectan a las actitudes de manera negativa y positiva, respec-tivamente. Los resultados de tres grupos focales permitieron profundizar en las explicaciones sobre los hallazgos cuantitativos y revelaron que otros factores, como los cálculos matemáticos, el lenguaje de la química y la metodología del profesor, también son relevantes en el desarrollo de las actitudes hacia la química. Se discuten estos hallazgos y sus implicaciones para la enseñanza de la química en Chile y Latinoamérica

Mathematics anxiety (MA) has primarily been studied in adults and children over 8 years of age in English-speaking countries. Few studies have examined MA in younger children and in Spanish-speaking contexts due to the lack of suitable instruments. In the present study we examine the psychometric properties of the Child Mathematics Anxiety Questionnaire (CMAQ-R), an instrument widely used in English-speaking primary school children. A total of 810 Chilean second-grade students (50% boys) from different school types (26% public, 11% private, 63% private-subsidised) completed a Spanish version of CMAQ-R. The results showed adequate internal consistency in line with the original instrument. Confirmatory factor analyses showed that scores from the CMAQ-R version best fit a two correlated-factor structure, which was invariant across gender and school type. This study offers evidence regarding the usefulness of the CMAQ-R in contexts culturally different to the original and supports the multidimensionality of MA.

The central purpose of the present study is to assess the early numeracy skills of Chilean kindergarten students, taking into consideration the socioeconomic status (SES) of the schools they attend. A sample of 19 urban schools and 498 students were used for the study. Research Findings: The data analysis showed statistical differences in the results of students from low SES schools compared with medium and high SES schools in four symbolic number tasks: counting fluency, oral number identification, oral number comparison, and non-oral number comparison. Hierarchical regression analyses revealed a direct contribution of school vulnerability index, non-symbolic number tasks, and symbolic number tasks in number comparison performance. These analyses also revealed that school vulnerability index made a loose predictive contribution when symbolic number tasks were introduced into the model. Practice or Policy: The achievement gap detected in the early stages of formal education will most likely increase with time. Early detection of mathematics learning difficulties, effective intervention, and training of teaching staff may be means of equalizing the performance of students from different socioeconomic backgrounds.

It is well-known that teacher expectations tend to be biased by factors such as student socio-economic status (SES) and gender. However, much less research has been devoted to understanding how teacher characteristics may impact their own expectations of the students. The present study investigated teacher expectations for 343 Chilean teachers (240 in-service and 103 pre-service). We first designed and validated an instrument to measure expectations; then we assessed the effect of teacher gender and experience, and student gender and school-SES in the formation of teacher expectations. The data were analysed using hypothesis and data-driven analyses. The results showed that SES had an effect on teacher expectations (2= .03 to .12); there was a higher probability that teachers from high-SES schools would have positive expectations of their students. However, negative expectations were equally distributed across teachers working in high and low-SES schools. There was also no evidence of the effect of teacher or student gender on teacher expectations. With respect to teacher experience, the findings were clear cut; both pre-service and in-service teachers shared identical expectations of their students. These findings have important implications regarding teacher training programmes since the expectation bias is observed very early during training.

Research into attitudes towards chemistry in Latin America and indeed towards science in general is very limited. The present study aimed to adapt and validate a shortened version of Bauer's Attitude toward the Subject of Chemistry Inventory version 2 (ASCIv2) for use in a Latin American context. It also explored attitudes towards chemistry of Chilean secondary school students, and assessed the effect of school type, year group, gender, and chemistry achievement on both cognitive and affective dimensions. The participants were 523 secondary school students from public, private subsidised, and private schools in Chile. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were first carried out to validate ASCIv2. The results of CFA showed that ASCIv2 retained the two-factor structure and showed optimal model fit, but three items had to be removed from the original instrument. The research also showed that attitudes towards science were neither positive nor negative, a reality similar to that of other countries. The results of multivariate and univariate analyses of variance showed significant effects of year group and chemistry achievement on attitudes towards chemistry. No effects of school type, gender or interactions between factors were found. Follow-up analyses revealed that as students advance through school their attitudes decline, but that the higher their chemistry marks, the more positive their attitudes become. These findings are partially in line with previous data from other countries and are a starting point for more research into attitudes towards chemistry in Latin America.

The present study compares the patterns of growth of beginning reading skills (i.e., phonemic awareness, phonics, fluency, vocabulary and comprehension) of Spanish speaking monolingual students who received a Tier 2 reading intervention with students who did not receive the intervention. All the students in grades K-2 were screened at the beginning of the year to confirm their risk status. A quasi-experimental longitudinal design was used: the treatment group received a supplemental program in small groups of 3 to 5 students, for 30 minutes daily from November to June. The control group did not receive it. All students were assessed three times during the academic year. A hierarchical linear growth modeling was conducted and differences on growth rate were found in vocabulary in kindergarten (p < .001; variance explained = 77.0%), phonemic awareness in kindergarten (p < .001; variance explained = 43.7%) and first grade (p < .01; variance explained = 15.2%), and finally we also find significant growth differences for second grade in oral reading fluency (p < .05; variance explained = 15.1%) and retell task (p < .05; variance explained = 14.5%). Children at risk for reading disabilities in Spanish can improve their skills when they receive explicit instruction in the context of Response to Intervention (RtI). Findings are discussed for each skill in the context of implementing a Tier 2 small group intervention within an RtI approach. Implications for practice in the Spanish educational context are also discussed for children who are struggling with reading.
