The Long Road to Developing Native Herbaceous Summer Forage Legume Ecotypes

Only a handful of well-adapted herbaceous summer forage legumes are currently marketed for drier regions of North America and even fewer are true natives. There is a growing demand for native germplasm in the region as a new generation of landowner attempts to return grasslands to a semblance of their original species and diversity. The objective of this paper is to describe preliminary research results of a grasslands team collecting, studying and promulgating native leguminous germplasm in Texas

Becoming Better Versed: Towards Design of Popular Music-based Rhyming Game for Disadvantaged Youths

This study examines patterns of rhyme identification among English Language Learners (ELLs) towards the development of an educational game, JOLLY, intended to improve phonemic awareness among school-aged children in the Philippines. Leveraging on students’ intrinsic interest in Western popular music, we ask students to identify rhyming words from among the song lyrics. We find that the extent to which an English phoneme is similar to a Tagalog phoneme determines how likely it is to be identified. From these findings, we draw implications on how JOLLY’s underlying domain model can be structured with each song as a learning object and each learning object consisting of an inventory of phonemes to be mastered. We also recommend the use of open, possibly social, student models to help learners track their progress and that of their peers

Predicting Math Success in an Online Tutoring System Using Language Data and Click-Stream Variables: A Longitudinal Analysis

Previous studies have demonstrated strong links between students\u27 linguistic knowledge, their affective language patterns and their success in math. Other studies have shown that demographic and click-stream variables in online learning environments are important predictors of math success. This study builds on this research in two ways. First, it combines linguistics and click-stream variables along with demographic information to increase prediction rates for math success. Second, it examines how random variance, as found in repeated participant data, can explain math success beyond linguistic, demographic, and click-stream variables. The findings indicate that linguistic, demographic, and click-stream factors explained about 14% of the variance in math scores. These variables mixed with random factors explained about 44% of the variance

Capim-elefante anão sob pastejo. II. Valor nutritivo.

O valor nutritivo do capim-elefante anão (Pennisetum purpureum Schum.) foi estudado num ensaio de pastejo. Pressão de pastejo (PP) e ciclo de pastejo (CP) foram aplicados em cinco níveis cada: PP-500, 1.000, 1.500, 2.000 e 2.500 kg de MS de folha residual ha-1 após o pastejo e CP-0 (pastejo contínuo), 14, 28, 42 e 56 dias. Cada CP incluiu dois dias de pastejo e um período de descanso específico para cada nível. O desenho experimental foi um composto central, não-rotável, com treze combinações em duas repetições. O modelo usado foi o polinômio completo do segundo grau. A proteína bruta das folhas e dos colmos aumentou com a elevação da PP e diminuição do CP. A digestibilidade in vitro das folhas, colmos e "forragem consumida" pareceu responder quadraticamente ao CP. As PPs mais altas tenderam a favorecer a digestibilidade dos colmos. A proteína da "forragem consumida" foi estimulada por CPs curtos. O ponto ótimo para digestibilidade da "forragem consumida" ficou em torno da combinação de 1.500 kg de MS de folha residual ha-1 de PP com 14 dias de CP. O valor nutritivo das folhas foi bem maior que o dos colmos, e a excelente qualidade da "forragem consumida" revelou o grande potencial desse capim sob pastejo

Ibigkas!: The Iterative Development of a Mobile Collaborative Game for Building Phonemic Awareness and Vocabular

Filipino learners’ lack of English language proficiency is a major barrier to higher education opportunities and participation in high-value industries. Computer-based learning systems have the potential to increase educational quality, equity, and efficacy in the Global South. However, a key challenge is to design systems that are developmentally and socioculturally appropriate and engaging for the target learners. In this paper, we describe the design, development, and preliminary testing of Ibigkas!, a collaborative, mobile phone-based game designed to provide phonemic awareness and vocabulary building support to Filipino learners aged 10-12

Understanding interactions in face-to-face and remote undergraduate science laboratories

This paper reviews the ways in which interactions have been studied, and the findings of such studies, in science education in both face-to-face and remote laboratories. Guided by a systematic selection process, 27 directly relevant articles were analysed based on three categories: the instruments used for measuring interactions, the research findings on student interactions, and the theoretical frameworks used in the studies of student interactions. In face-to-face laboratories, instruments for measuring interactions and the characterisation of the nature of interactions were prominent. For remote laboratories, the analysis of direct interactions was found to be lacking. Instead, studies of remote laboratories were mainly concerned with their practical scope. In addition, it is found that only a limited number of theoretical frameworks have been developed and applied in the research design. Existent theories are summarised and possible theoretical frameworks that may be implemented in studies of interactions in undergraduate laboratories are proposed. Finally, future directions for research on the interrelationship between student interactions and laboratory learning are suggested
