Effects of segmenting,signalling, and weeding on learning from educational video

Informed by the cognitive theory of multimedia learning, this study examined the effects of three multimedia design principles on undergraduate students' learning outcomes and perceived learning difficulty in the context of learning entomology from an educational video. These principles included segmenting the video into smaller units, signalling to direct students' attention to relevant information, and weeding to remove any non-essential content (SSW). It was hypothesized that the SSW treatment would decrease perceived learning difficulty and facilitate the transfer of knowledge and the structural knowledge acquisition. Results of the study demonstrate that participants in the SSW group outperformed the non-SSW group on the tests of knowledge transfer and structural knowledge acquisition and reported lower levels of learning difficulty. These findings support the use of SSW to help novice learners organize and integrate knowledge from complex, dynamic audio-visual media like video.     

Students’ conception of infinite series

This is a report of a study of students’ understanding of infinite series. It has a three-fold purpose: to show that students may construct two essentially different notions of infinite series, to show that one of the constructions is particularly difficult for students, and to examine the way in which these two different constructions may be built so that we may uncover ways to help students improve their understanding. The theoretical framework consists of action–process–object–schema theory and the specific model of conceptions in Balacheff’s theory of conception, knowing, and concept. Approaching the problem from these two different theoretical perspectives allows us to provide different and at the same time complementary explanations of observed phenomena. The two different infinite series constructions are, briefly stated, series as an infinite unending process of addition and series as a sequence of partial sums. Students are found to have difficulty building an understanding of series as a sequence of partial sums and thus tend to have difficulty in problem situations that require this interpretation. The study uses semi-structured interviews with 10 graduate students. The interviews explore situations that might give insight into students’ notion of the sequence of partial sums.     

Does TV Viewing Cultivate Meritocratic Beliefs? Implications for Life Satisfaction

The purpose of this article was to explore the cultivation effects of television viewing on meritocratic belief systems (particularly, system justification) and ultimately on perceived life satisfaction. Results of a cross-sectional survey (N = 276) reveal that genre-specific TV viewing cultivates system-justifying beliefs. More specifically, findings suggest that heavy viewing of competition-based reality TV viewing shapes viewers' economic system-justifying beliefs (i.e., the belief that the economic system is fair and legitimate, rewarding those who put in the effort and hard work). Economic system justifying beliefs, in turn, were shown to enhance viewers' perceived life satisfaction.     

Procesos cognitivos en el aprendizaje de la multiplicación

Resumen

En este trabajo se aborda el estudio de los procedimientos y estrategias desarrollados por los niños para solucionar situaciones problemáticas relacionadas con la multiplicación aritmética. El análisis de dichos procedimientos nos muestra cómo dicha noción comporta un nivel de mayor complejidad que la adición, lo que es necesario tener en cuenta en el momento de enseñarla.     

Resisting Erasure and Developing Networks of Solidarity: Testimonios of Two Puerto Rican Scholars in the Academy

In this article, we share findings from a critical qualitative study aimed at better understanding the ways that language, history, and geography mediate our work and identities as educational researchers. As scholars whose particular sociocultural and political histories are often absent in scholarly discussions about language and education, we use the intergenerational sharing of testimonios as both methodology and narrative development to gain a deeper understanding of experiences involving the learning and use of English that influence our academic careers. We theorize our experiences as resisting erasure and contribute to Latina epistemology scholarship and critical educational research about Puerto Ricans in the United States. Moreover, we forward the concept of funds of knowledge as a professional practice. Telling our stories and developing mentoring networks is necessary for our individual and collective functioning and well-being as scholars; it cultivates solidarity as a means of thriving in the academy.     

Validating a model of effective teaching behaviour and student engagement: perspectives from Spanish students

Research consistently shows that teaching behaviour is a highly-important indicator of learning environments. Based on a teacher effectiveness model with six observable teaching behaviour domains (safe learning climate, efficient classroom management, clarity of instruction, activating teaching, teaching–learning strategies, and differentiation), the present paper examines the psychometric quality of the My Teacher questionnaire for capturing student perceptions of teaching behaviour in the Spanish secondary-education context. Additionally, this study validated the model of teaching behaviour and student engagement and its relevance in Spain. 7114 students of 410 teachers attending 56 public and private Spanish schools constituted the sample. The six teaching behavioural dimensions model were confirmed in the Spanish context. Regarding student academic engagement, the presence of two domains (behavioural and emotional engagement) were confirmed. Furthermore, results of a multiple-group structural equation modeling path analysis, examining the relationship between teaching behaviour and student engagement across different teaching experiences, revealed differential effects of teaching behaviour influences on students’ engagement. The percentage of explained variance was larger for emotional engagement than for behavioural engagement. Furthermore, teachers’ teaching experience explained differences in the relationship between perceived teaching behaviour and engagement. Two domains (learning climate and activating teaching) appeared to be the two most-important teaching domains for students’ behavioural engagement while, for emotional engagement, the most important domains for student engagement were learning climate and teaching learning strategies.
