Learning molecular behaviour may improve student explanatory models of the greenhouse effect

We assessed undergraduates’ representations of the greenhouse effect, based on student-generated concept sketches, before and after a 30-min constructivist lesson. Principal component analysis of features in student sketches revealed seven distinct and coherent explanatory models including a new Molecular Details model. After the lesson, which described the invisible molecular behaviour of gases, this group (n = 164) produced significantly more expert-like representations of the greenhouse effect, and included fewer novice ideas. The key behaviour that greenhouse gases emit radiation in random directions is new to most students and directly counters common explanations involving reflection and ‘trapping’ of radiation in the atmosphere. Thus, learning molecular behaviour of greenhouse gases may help students replace non-expert explanatory models. This Molecular Details model has not been previously identified, and is unlikely to have emerged from human evaluation of student sketches alone. When teaching the greenhouse effect, we propose that interventions explicitly incorporate greenhouse gas behaviour.     

Children’s attitudes toward small computers: a preliminary study

While it has been established that children have positive attitudes toward the use of computers when used in computer-assisted instruction, little is known about children’s attitudes toward small“home” or“personal” computers. Results of this study indicate that children have multidimensional attitudes toward small computers, their interaction with these computers, and ease of use.     

Collaborating with colleagues for the sake of academic and professional development in higher education

Abstract

This research examines how faculty members in higher education collaborate with colleagues, their collaborative professional work, the nature of these collaborations, and the benefits they get from it. Research findings show that collaborations are perceived as one of the important components of academic and professional development. The findings indicate issues about the characteristics and nature of collaborations as well as about colleagues with whom faculty members prefer to collaborate, the ways in which they collaborate, the advantages of collaborations, and the important role that academic leaders and institutions play in encouraging collaborations.     

Is peer review an appropriate form of assessment in a MOOC? Student participation and performance in formative peer review

Many aspects of higher education must be reconceptualised for massive open online courses (MOOCs). Formative and summative assessment of qualitative work in particular requires novel approaches to cope with the numbers involved. Peer review has been proposed as one solution, and has been widely adopted by major MOOC providers, but there is currently little evidence about whether it is appropriate or under what conditions. Here, we examine student participation, performance and opinions of a peer review task in a biomedical science MOOC. We evaluate data from approximately 200 student topic summaries and 300 qualitative peer reviews of those summaries, and compare these to student demographic data (gender, age, employment status, education, national language) and to performance in multiple choice tests. We show that higher performance in the written topic summary correlated with both higher participation in the peer review task and with writing higher quality peer reviews. Qualitative analysis of student comments revealed that student opinion on the usefulness of the peer review task was mixed: some strongly believed it benefitted their learning, while others did not find it useful or did not participate. We suggest instructional design strategies to improve student participation and increase learning gain from peer review in the MOOC context.     

Teaching Practices that Promote Motor Skills in Early Childhood Settings

Early childhood educators, especially those in preschool centers, are often expected to design and implement movement programs. However, these individuals may not have been taught these skills during their education. The purpose of this study was to determine if early childhood majors could successfully be taught to implement a mastery climate instructional approach to promote motor skill development to preschool-age children. Twenty undergraduate Early Childhood Education majors, who completed a Motor Development Across the School Years course, designed and implemented a movement program to develop preschoolers’ locomotor and object control skills. Fourteen preschoolers participated in an 11-week movement program. Preschoolers’ motor performance was assessed with the Test of Gross Motor Development—2nd Edition prior to and following the intervention. Results indicate significant improvements in total performance (p < .05) and locomotor skills (p = .037). Findings indicate that with guidance and training, early childhood majors can effectively design and implement a mastery-based movement program that enhances motor skill competence. The findings also demonstrate the need and value for early childhood majors to receive training in the design and implementation of movement programs. This paper provides a conceptual framework and practical recommendations to assist teachers and educators with implementing a mastery climate movement programs.     

Children’s morphological awareness and reading ability

We investigated the effects of morphological awareness on five measures of reading in 103 children from Grades 1 to 3. Morphological awareness was assessed with a word analogy task that included a wide range of morphological transformations. Results indicated that the new measure had satisfactory reliability, and that morphological awareness was a significant predictor of word reading accuracy and speed, pseudoword reading accuracy, text reading speed, and reading comprehension, after controlling the effects of verbal and nonverbal ability and phonological awareness. Morphological awareness also explained variance in reading comprehension after further controlling word reading. We conclude that morphological awareness has important roles in word reading and reading comprehension, and we suggest that it should be included more frequently in assessments and instruction.     

Bien Educado: Measuring the social behaviors of Mexican American children

Young children's expected social behaviors develop within particular cultural contexts and contribute to their academic experience in large part through their relationships with their teachers. Commonly used measures focus on children's problem behaviors, developed from psychopathology traditions, and rarely situate normative and positive behaviors in context. Building from the literature on parenting goals and socialization expectations in Latino families and a preliminary ethnographic study (Proyecto Educando Niños), we constructed a survey in English and Spanish that measures the expected social behaviors of Mexican-heritage children, ages 3–6 years, using parent and teacher reports. Use of the BEAR Assessment System facilitated the refinement of this instrument to assess the socialization of young, Mexican American children. We report on the psychometric properties of the Mexican American Socialization (MAS) Scale, utilizing item-response theory. Analyses indicate the MAS Scale is reliable and an ecologically valid indicator of multiple constructs of the expected social behaviors of young Mexican American children. In particular, the 41-item Bien Educado subscale showed good reliability and is consistent with socialization constructs described in the literature. Implications for research and practice are discussed.
