Optimal release conditions for the free throw in men's basketball

Abstract

The purpose of this study was to determine the optimum release conditions for the free throw in men's basketball. The study used hundreds of thousands of three-dimensional simulations of basketball trajectories. Five release variables were studied: release height, release speed, launch angle, side angle, and back spin. The free throw shooter was assumed to shoot at 70% and to release the ball 2.134 m (7 ft) above the ground. We found that the shooter should place up to 3 Hz of back spin on the ball, should aim the ball towards the back of the ring, and should launch the ball at 52° to the horizontal. We also found that it is desirable to release the ball as high above the ground as possible, as long as this does not adversely affect the player's launch consistency.     

A revised model of e-brand equity and its application to high technology products

Given the growing importance of online social media platforms (OSM) in brand management, the authors attempt to extend the relationship between e-brand equity and repurchase intention with two mediator variables, namely visual appeal and e-preference in which willingness to pay a price premium (WPPP) serves as a moderator. Drawing on the perspective of digitalized engagement (PDE), the authors confirm the mediating effects on the e-brand equity-repurchase intention link while evidencing both positive and negative effects of WPPP on the linkage of e-brand equity and mediators. Contributions to theory, practice, and future studies are also provided.     

Examining IEPs of English Learners with Learning Disabilities for Cultural and Linguistic Responsiveness

Effective education of English learners (ELs) with learning disabilities requires special educators to deliver culturally/linguistically responsive instruction within the context of special services, embracing the interaction between exceptionality and diversity. A critical concept is the notion that cultural and linguistic features are mandated by law to remain integral to teaching and learning once ELs are appropriately placed for special services. We examined a sampling of IEPs for ELs receiving special education for learning disabilities for cultural/linguistic responsive features to inform instruction. We found from our pilot study that the IEPs contain little to no reference to ELs' diverse linguistic and cultural qualities to (1) meet legislative mandates, and (2) guide delivery of appropriate special education. Practitioner implications for developing culturally and linguistically responsive IEPs are provided to support educators who teach ELs with learning disabilities.     

Teasing apart the child care conundrum: A factorial survey analysis of perceptions of child care quality, fair market price and willingness to pay by low-income, African American parents

Child care quality plays a crucial role in children's social and cognitive development. While child care quality is a critical issue for all children, it matters more for low-income children. Policy makers have increased the emphasis on allowing parents, not government, to make decisions about the type of care they want for their children. Yet most research on child care quality has focused on how child care professionals, not parents define high quality care. This study investigates how low-income families evaluate child care quality by examining the child care preferences of a sample of low-income African American parents. We employ the factorial survey method, a method used in sociological research to assess people's perceptions and rankings of individual attributes associated with complex multidimensional phenomena. The factorial survey method permits a simultaneous assessment of how respondents evaluate and make tradeoffs among multiple child care characteristics. We assess the impact of child care characteristics on respondents’ perceptions of child care desirability, fair market value, and willingness to pay. Findings indicate that parents’ definition of quality focused squarely on the care giving environment, specifically the qualifications, experience, training and behavior associated with the child care provider. The type of care facility—family, center, relative or neighbor care was largely irrelevant to this sample of parents. Parents believed that the characteristics they defined as desirable child care situations were worth more, and parents were willing to pay more for these characteristics. These parents also defined quality in terms of race and class, and they wanted racial and economic diversity. This research suggests parents may choose lower quality care, not because they do not know what quality is or because they define quality care differently, but because such care may be neither available nor affordable in their communities.     

Professional Development for Teachers Working with International Students

The commercialisation of education and the massive recruitment of international students across different vocational education and training (VET) systems including the US, UK, Canada and Australia have led to significant changes in the VET teaching and learning landscape. This situation compels the VET sector to design and develop new professional development programs to support the immediate and changing needs of teachers working with the diverse international student cohort. However, to date, teacher professional development in response to the growing population of international students has not been an explicit focus of empirical study and theoretical conceptualisation in VET research. This study responds to this paucity. It draws on a broader three-year research project funded by the Australian Research Council (2014–2017) that involves fieldwork, participation in and observation of staff professional development activities and interviews with 102 VET staff in Australia. It uses positioning theory as a conceptual framework to examine how VET teachers position themselves and their professional development needs in response to international students. The results call for a critical need to re-examine the focus of the current professional development programs offered for VET teachers. The current context requires teacher professional development in international VET to focus on developing teachers’ capabilities to re-examine their pedagogical beliefs and practices and to understand international students’ various needs and cultural backgrounds. The study also stresses the importance of ongoing professional learning to equip teachers with the skills and knowledge to appropriate their pedagogical practices in response to the critical need to prepare all students for the intercultural labour market and to use students’ diversity as a resource for teaching and learning.     

Preparing Teachers to Use GIS: The Impact of a Hybrid Professional Development Program on Teachers’ Use of GIS

This article reports the findings of a 3-year study of a hybrid professional development program designed to prepare science and mathematics teachers to implement GIS in their classrooms. The study was conducted as part of the CoastLines Innovative Technology Experiences for Students and Teachers project funded by the National Science Foundation. Three cohorts of teachers participated in the program, with each participant receiving 40 h of synchronous online instruction and 80 h of in-person instruction and support over an 8-month period. Data from surveys of participants both before and after the program were analyzed using correlation, ordinary least squares, and ordered logit regression analyses. The analyses revealed increases in the self-reported frequency of GIS use and enhanced feelings of preparation, competence, community, and comfort with respect to using GIS for instruction. A composite index of all impact variables was positively influenced as well. The statistical analyses found a strong relationship between self-reported feelings of preparation and use of GIS. Some support was found for the idea that feelings of competence, community, and comfort were related to the teachers’ sense of preparation. The findings suggest that a robust hybrid model of teacher professional development can prepare teachers to use GIS in their classrooms. More research is needed to understand how hybrid models influence the sociopsychological and other dimensions that support teachers’ feelings of preparation to implement GIS.

     

Evaluating the Benefits and Values of Textbooks: Perceptions of Vietnamese Business Students

This study aims to examine students’ perceived benefits and values of textbooks, with a specific focus on emerging markets. A paper-based survey was used to collect data from 459 Vietnamese students in three business disciplines including accounting, international business and marketing. The findings reveal that Vietnamese business students view textbooks as having greater short-term benefits than long-term ones. They also believe that textbooks have relatively low economic value. Interestingly, marketing students perceive that textbooks provide primarily benefits of improving class performance, while accounting students tend to view textbooks to have benefits of clearer understanding of relevant concepts. Implications for key stakeholders in the higher education book publishing industry are discussed and future research directions presented.

Is the learning approach of students from the Confucian heritage culture problematic?

This article is concerned with the learning style adopted by Asian students who come from a Confucian heritage culture (CHC) such countries as China, Vietnam, Singapore, Korea and Japan are considered countries with Confucian heritage culture (Phuong-Mai et al. 2005). These students are generally viewed as typically passive, unwilling to ask questions or speak up in class and often based on memorising rather than understanding knowledge delivered by teachers. This learning style is claimed to be shaped by the CHC in Asian countries and receives massive criticism in the literature. This article aims to challenge this criticism of the passive learning style adopted by Asian students who come from the CHC. By conducting in-depth interviews with 10 Asian students from the CHC currently studying tertiary education in Australia, this article addresses the confusion between passive learning style and CHC, between memorising and understanding and between quietness and passiveness. Finally, if passiveness of Asian students is indeed observed in both Asian CHC countries and English-speaking countries, it is more because of situation-specific factors of teaching methodologies, learning requirements, learning habits and language proficiency rather than cultural factors.
