The combined use of IRT and LDV for the investigation of historical thin vaults

Correct interventions on cultural heritage should have as their starting point an accurate diagnosis of its health, in order to design a compatible care. NDTs seem to offer a promising way in this sense. This paper deals with the combined use of IRT and LDV for the investigation of historical thin vaults made by timber arches, reeds, and plaster and it demonstrates that they can effectively support a deeper knowledge of these vaults as it concerns the presence of detached areas among the different mortar layers of the plaster and of detached areas among the mat of reeds and the nailed connection with the wooden bearing elements. This is a very important goal because these ND methodologies can be employed only on the lower surface of these vaults and sufficiently far from it, and they do not have any mechanical interaction with the historical, eventually frescoed or stuccoed, plaster, thus saving money and time.     

“Spanish as a foreign language” teachers’ profiles: inclusive beliefs, teachers’ perceptions of student outcomes in the TCLA program, burnout, and experience

The present study focuses on the Temporary Classroom of Linguistic Adaptation program (TCLA program) in which specialist teachers (Spanish as a foreign language teachers—SFL teachers) teach Spanish to immigrants who are not proficient in the language. We suggest that support for immigrant students in Spanish schools should adopt a new inclusive educational approach. The present investigation is a preliminary attempt at characterizing the profiles of SFL teachers by assessing, simultaneously, five relevant variables (through cluster analysis): inclusive beliefs, teachers’ perceptions of student outcomes in TCLA program, general burnout, diversity-related teacher burnout, and years of teaching experience. Eighty-one SFL teachers from 132 schools in Spain (EU) were asked to complete a self-report questionnaire. Cluster analysis found two clearly differentiated groups: the larger one, Innovative SFL Teachers and the smaller, Traditional SFL Teachers. The Traditional SFL Teachers are characterized by more years of experience, lower inclusive beliefs scores, lower teachers’ perception of student outcomes in the TCLA program scores, and higher burnout scores as compared with the Innovative SFL Teachers. Moreover, Traditional SFL Teachers conceptualize their teaching role as a "teacher of Spanish" whereas Innovative SFL Teachers see themselves much more as playing a supportive role.     

La integración de la representación audiovisual en la Reforma Educativa

La palabra y la imagen son los grandes medios para la comunicación pedagógica. En este artículo se analizan la perspectiva y posibilidades que la LOGSE (cuyos presupuestos, se afirma, apuestan casi al cien por cien por el medio verbal) ofrece para contar con la comunicación audiovisual en la educación.     

Identificación y análisis de valores y construcción conceptual

En este artículo se presentan las diferentes fases de aplicación de la estrategia de análisis y comprensión conceptual, insistiendo en la metodología y papel del profesor en el uso de dicha técnica. Se propone una actividad para el primer ciclo de la Educación Primaria y otra para el segundo ciclo de la Educación Secundaria.     

Interacción entre iguales,medio social y desarrollo cognitivo

Resumen

En este trabajo se estudia la utilidad de la interacción entre iguales para el desarrollo cognitivo; 874 sujetos de 11–14 años de edad, de dos medios sociales diferentes, resuelven individualmente dos tests de inteligencia (el TIG-1, y los tests de factor g, de Cattell). El tratamiento consiste en el estudio de una de las dos pruebas en grupos formados según medio social y agrupación para la tarea (díadas, individual). Los resultados de la evaluación de los rendimientos diferenciales, pre-postests en ambas pruebas según el MS y el agrupamiento (Anovas 2 X 2), indican una clara incidencia de ambas variables, en especial en las pruebas de «generalización». Los mayores progresos corresponden a los sujetos de medio social desfavorecido, a las agrupaciones diádicas y al tratamiento con el test Cattell. Se discute, a la luz de las teorías del conflicto sociocognitivo, el interés de este tipo de intervención, particularmente en sujetos de medios socioculturales deprivados.     

Building personalised homework from a learning analytics based formative assessment: Effect on fifth-grade students' understanding of fractions

This study analyses the potential of a learning analytics (LA) based formative assessment to construct personalised teaching sequences in Mathematics for 5th-grade primary school students. A total of 127 students from Spanish public schools participated in the study. The quasi-experimental study was conducted over the course of six sessions, in which both control and experimental groups participated in a teaching sequence based on mathematical problems. In each session, both groups used audience response systems to record their responses to mathematical tasks about fractions. After each session, students from the control group were given generic homework on fractions—the same activities for all the participants—while students from the experimental group were given a personalised set of activities. The provision of personalised homework was based on the students' errors detected from the use of the LA-based formative assessment. After the intervention, the results indicate a higher student level of understanding of the concept of fractions in the experimental group compared to the control group. Related to motivational dimensions, results indicated that instruction using audience response systems has a positive effect compared to regular mathematics classes.

Practitioner notes

What is already known about this topic

• Developing an understanding of fractions is one of the most challenging concepts in elementary mathematics and a solid predictor of future achievements in mathematics.
• Learning analytics (LA) has the potential to provide quality, functional data for assessing and supporting learners' difficulties.
• Audience response systems (ARS) are one of the most practical ways to collect data for LA in classroom environments.
• There is a scarcity of field research implementations on LA mediated by ARS in real contexts of elementary school classrooms.

What this paper adds

• Empirical evidence about how LA-based formative assessments can enable personalised homework to support student understanding of fractions.
• Personalised homework based on an LA-based formative assessment improves the students' comprehension of fractions.
• Using ARS for the teaching of fractions has a positive effect in terms of student motivation.

Implications for practice and/or policy

• Teachers should be given LA/ARS tools that allow them to quickly provide students with personalised mathematical instruction.
• Researchers should continue exploring these potentially beneficial educational implementations in other areas.
