Distinguishing technologies for social interaction: The perceived social affordances of communication channels scale

The concept of affordances in communication technology research has proven to be heuristically provocative, yet perceived affordances are rarely measured. After extracting commonly cited social affordances from the literature, we developed a measure to assess participants’ perceptions of these affordances. The scale was tested across eight communication channels in two studies (face-to-face; texting; phone; email; posts on social networking sites, specifically Facebook; instant messaging; Skype videoconferencing; and mobile app Snapchat). A factor structure was developed in Study 1 and confirmed in Study 2. The resultant Perceived Social Affordances of Communication Channels Scale includes 41 items measuring 10 communicative affordances: accessibility, bandwidth, social presence, privacy, network association, personalization, persistence, editability, conversation control, and anonymity. Potential methodological and theoretical applications are discussed.     

Evaluating multigrade school reform in Latin America

This paper describes three multigrade school reforms in Latin America: (1) Colombia’s Escuela Nueva, (2) Guatemala’s Nueva Escuela Unitaria, and (3) Chile’s MECE‐Rural. Each reform endowed primary teachers and students with special training and instructional materials, and encouraged new kinds of instruction in rural classrooms, with the goal of improving student learning. The paper discusses the challenges to evaluating school reforms in a rural context. It then reviews the international literature on each reform, assessing whether reforms were effectively implemented and whether they caused improvement in student outcomes. Even in the best cases, multigrade schools were not fully implemented. There is consistent evidence of positive effects on student achievement. Yet, the causal interpretation of evaluation findings is severely limited, especially in Guatemala and Chile. It concludes with suggestions for improving multigrade evaluations.     

Giving Till it Helps? Alumnae Giving and Children’s College Options

This paper examines whether donations to colleges and universities are partly motivated by the desire of alumni to increase their children’s admissions probabilities. The paper uses data from a single-sex college, so that only alums with a daughter would evince this motive. We find that alums with a teenage daughter, as opposed to a teenage son, are more likely to make donations of at least $5,000. The same relationship is not evident for smaller donations, or when children are older than 18. Further, we find evidence that this difference in the probability of a donation by alums with teenage daughters and teenage sons does not exist when acceptance rates are higher in an earlier period.     

The achievement of indigenous students in Guatemalan primary schools

This paper analyses the difference in academic achievement between indigenous and nonindigenous children that attend rural primary schools in Guatemala. The gap ranges between 0.8 and 1 standard deviation in Spanish, and approximately half that in Mathematics. A decomposition procedure suggests that a relatively small portion of the achievement gap is explained by differences in the socioeconomic status of indigenous and nonindigenous families. Other results are consistent with the notion that school attributes play an important role in explaining the achievement gap. The paper discusses several explanations—such as the lack of bilingual education—that are consistent with the empirical findings.     

Constraints to Implementing Educational Innovations: The Case of Multigrade Schools

Studies suggest that multigrade schools, i.e. those with classes that are mixed in age and ability, can be a cost-effective means of raising student achievement and expanding access to education in poor countries. Development institutions often recommend them for countries struggling to raise educational quality and coverage in rural areas. However, the literature advocating the adoption of multigrade schools avoids discussing the potential difficulties in implementing the system. This paper analyses the conditons under which implementation might be successful, focusing on the oft-cited case of the Colombian Escuela Nuela programme. The authors conclude that capacity-building through in-service training is an important determinant of the way teachers approach their task. However, a great deal of variance in teacher practices is left unexplained. The article suggests that teacher will (that is, motivation and commitment) might explain much of the remaining variation in the adoption of the new pedagogies. The authors explore several conditions under which teacher will could be lacking.
