At the end of every semester, some students will boldly email me asking for their grade to be bumped. These requests and their motives seem closely tied to academic entitlement, which has mostly been studied quantitatively. Creating a dialogue with this published literature, this research seeks to uncover the lived meanings of a grade perceived as unjust. Using a Heideggerian life-world approach, I analyzed an email archive to explore how students are projecting lived understandings of themselves that are at odds with their grades. In their plaintive plea to change their grades, the students are seeking affirmation of their self-understanding, demanding to be seen and valued as they see themselves. These results are discussed in light of the literature reviewed and directions for future research are proffered.

The aim of the research is to relate the middle school students’ literacy skills to their basic language skills. The study was designed as an action research. The participants of the study are middle school students. The data collection tool consists of semi-structured interview form, semi-structured observation form, log form and activity files. The research process was carried out in three stages: cultural awareness, cultural diversity and cultural literacy. It was observed that participants cultural literacy skills developed at each stage. In addition, while performing basic language skills, they were found to be more effective at every stage. Based on the results of the study, it is concluded that the mother language education lesson can be associated with the learning outcome of cultural literacy skills and basic language skills.

This study aimed at exploring novice researchers’ experiences of and perspectives on the qualitative research journey and determining the difficulties tackled and strategies developed while conducting qualitative research. The study was an interview-based qualitative case study involving nine graduate students in education as the participants. The data were collected between 2017 and 2019 at a state university located in Southeastern Turkey. The content-analyzed data revealed several findings about the research topic, indicating that the novice researchers considered the qualitative research journey as daunting and overwhelming, but pleasurable and satisfying. Despite scholarly development and lessons learned in the process, the researchers confronted with several difficulties concerning data collection, analysis and interpretation, recruitment and developing rapport, representation of findings, and the research process as a whole. They developed personal and external support strategies during the research journey. The metaphorical perceptions portrayed the elusive and distinctive nature of qualitative research.

Las interfaces cerebro-computadora (BCI) son sistemas que interpretan patrones de actividad cerebral para facilitar a personas con discapacidad motora o del habla, la comunicación o el control de dispositivos. Una forma de comunicación exitosa han sido los deletreadores basados en potenciales evocados de estado estable (SSVEP por sus siglas en inglés) que parten de la generación de estímulos visuales para provocar determinada actividad cerebral, registrarla e interpretarla mediante algoritmos de clasificación. Dentro de estos sistemas falta realizar un análisis para determinar un clasificador que tenga una relación tiempo de procesamiento y desempeño eficientes para aplicaciones en entornos controlados. En este trabajo se parte de la generación y registro de señales SSVEP, para realizar un análisis de desempeño de los clasificadores de árbol simple ST, y de máquinas de vectores de soporte SVM, los cuales son algoritmos de baja complejidad computacional encontrados en los métodos de análisis de SSVEP. De acuerdo a los resultados obtenidos, el porcentaje promedio de acierto del ST para una señal de 10 s fue de 84.58% para el canal O1 y un 78.75% para el O2; mientras que el del SVM fue 78.33%.
