This paper will examine the interaction hypothesis (IH) in second language acquisition (SLA). To begin with a short discussion of the confusing terms in SLA such as theory, model, hypothesis, and construct will be done so as to help readers easily understand theories in the field of SLA and related concepts. Next, what the IH is, and who proposed…

An item banking method that does not use Item Response Theory (IRT) is described. This method provides a comparable grading system across schools that would be suitable for low-stakes testing. It uses the Angoff standard-setting method to obtain item ratings that are stored with each item. An example of such a grading system is given, showing how…

Can infants, in the very first stages of word learning, use their perceptual sensitivity to the phonetics of speech while learning words? Research to date suggests that infants of 14 months cannot learn two similar-sounding words unless there is substantial contextual support. The current experiment advances our understanding of this failure by…

An experimental project aimed at identifying stable reaction intermediates is described. Initially, the studied reaction appears to involve the simple hydrolysis, by aqueous sodium hydroxide, of methyl 3,5-dinitrobenzoate dissolved in dimethyl sulfoxide. On mixing the substrates, however, the reaction mixture unexpectedly turns an intense red in…

The voices of parents are not often heard in the literature and, when they are, it tends to be a litany of battles with the schooling system to achieve or not achieve some sort of acceleration for their gifted children (Gross, 2004). This retrospective study is unusual, as it is not based on a history of conflict. It is a positive account of…

This study examined the relationship between a middle school initiative to develop student voice, interpersonal relationships, and intrapersonal relationships and students' sense of belonging. The literature indicated a strong connection between students' sense of belonging in school and positive outcomes in and out of the classroom (Deci &…

Under the umbrella of ubiquitous technologies, many computational artifacts have been designed to enhance the learning experience in physical settings such as classrooms or playgrounds, but few of them focus on aiding orchestration. This paper presents a systematic evaluation of the signal orchestration system (SOS) used by students for a jigsaw…

This study investigates the benefits of no-stakes educational testing during students' summer vacation as a strategy to mitigate summer learning loss. Fifty-one students in Grades 3-8 from the Every Child Valued (ECV) and Lawrence Community Center (LCC) summer programs in Lawrenceville, NJ, took short, online assessments throughout the summer,…

One fundamental way to determine the validity of standardized English-language test scores is to investigate the extent to which they reflect anticipated learning effects in different English-language programs. In this study, we investigated the extent to which the "TOEFL iBT"® practice test reflects the learning effects of students at…

The introductory computer programming (CP) course has been taught for three decades in the faculty. Besides pursuing CP technology, one major goal has been enhancing learners' problem-solving (PS) skills. However, the current situation has implied that this might not be the case. Therefore, a research was conducted to investigate the effects of a…

The main purpose of this study was to examine the effects of Problem-Solving Strategy Steps (PSSS) on students' achievement, skill, and confidence. The study was conducted in a two-year college classroom with 70 students from two different groups enrolled in a physics course. One of them was randomly selected as an experimental group (EG) and the…

Peer victimization is a known risk factor for various forms of maladjustment; however, the specific type of maladjustment may depend on individual differences in youth. This 2-wave longitudinal study examined the hypothesis that social approach-avoidance motivation, together with sex, would moderate the contribution of 3rd-grade victimization to…

Creative Commons (CC) mechanism has been suggested as a potential means to foster a reliable environment for online knowledge sharing activity. This study investigates the role of the CC mechanism in supporting knowledge sharing among a group of university students studying programming from the perspectives of social cognitive and social capital…

This study is based on our belief that mathematics should be challenging in any classroom and that mathematical challenge is among the central factors that determine the quality of mathematics lessons. Choosing challenging mathematical problem for the students is central in teachers' work while their conception of mathematical challenge can…

This paper describes an innovative Principles of Marketing course design and delivery which matches learning and teaching styles, while reducing multi-section variation. Value co-creation is encouraged by instructors and students collaborating in the creation of customized learning experiences which facilitates both teaching style and learning…
