Development of disjunctive reasoning and the use of MAYBE in fifth through eighth graders

Approximately one-half of the fifth through eighth graders in a school district (n = 164) were randomly selected to be administered a group test of disjunctive reasoning containing 48 inclusive and exclusive items varying in content of the premises (symbolic, object, and human), and affirmation or negation of the conclusion. Using an analysis of variance for repeated measures it was found that performance improved until seventh grade. Eighth graders scored similar to sixth graders. There was a main effect for negative, with negative conclusions producing more correct answers. Further, there were significant first order interactions for Disjunctive by Negation, Content by Grade, and Negation by Content. Since either “YES” or “NO” were the only correct answers, and “MAYBE” was always wrong, contrast of the MAYBE responses to other wrong answers revealed an increasing tendency to use MAYBE among older subjects. Implications were discussed in relation to cognitive developmental theory and educational practices.     

Acquisition of computer literacy skills through self-organizing systems of learning among children in Bhutan and India

This article describes a study under the Reaching the Unreached component of the Chiphen Rigpel project between the governments of Bhutan and India. This initiative is an attempt to provide computer literacy to children of Bhutan through setting up “hole in the wall” (HiWEL) Playground Learning Station(s) (PLSs). The study described here involves 14 sites (the experimental group), where PLSs are installed, and another 8 sites (the control group) without PLSs, but having similar demographic and socioeconomic profiling as the experimental group. This article compares the acquisition of computer literacy of school-going children in India with those in Bhutan. Results indicate that Bhutanese children have acquired computer literacy on their own and that their level of computer skills acquisition is similar to that of Indian children when the scores are normalized. This study was done over a one-year period, with results reported for eight months. In addition to verifying the earlier Indian results, this article hints at the fact that, irrespective of ethnicity, culture, and country, an identical—and possibly universal—self-organized learning mechanism seems to work with children vis-à-vis the Internet.

Tutor learning: the role of explaining and responding to questions

Previous research on peer tutoring has found that students sometimes benefit academically from tutoring other students. In this study we combined quantitative and qualitative analyses to explore how untrained peer tutors learned via explaining and responding to tutee questions in a non-reciprocal tutoring setting. In support of our hypotheses, we found that tutors learned most effectively when their instructional activities incorporated reflective knowledge-building in which they monitored their own understanding, generated inferences to repair misunderstandings, and elaborated upon the source materials. However, tutors seemed to adopt a knowledge-telling bias in which they primarily summarized the source materials with little elaboration. Tutors’ reflective knowledge-building activities, when they occurred, were more frequently elicited by interactions with their tutee. In particular, when tutees asked questions that contained an inference or required an inferential answer, tutors’ responses were more likely to be elaborative and metacognitive. Directions for future research are also discussed.     

Exploring the effects of gender and learning styles on computer programming performance: implications for programming pedagogy

Computer programming has been taught in secondary schools for more than two decades. However, little is known about how students learn to program. From the curriculum implementation perspectives, learning style helps address the issue of learner differences, resulting in a shift from a teacher-centred approach to a learner-focused approach. This study aims to investigate the effects of gender and learning styles on computer programming performance. The Gregorc Style Delineator (GSD) was employed to measure learning styles. A test was administered to assess students' programming performance. Two hundred and seventeen secondary school students of age from 14 to 19 participated in this study. Results indicated that no gender differences in programming performance were found after controlling for the effect of student ability. Academic ability had a differential effect on programming knowledge. Sequential learners in general performed better than random learners. These results suggest the importance of the ordering dimension of the GSD in influencing programming performance. Implications of the findings in relation to programming pedagogy are discussed in this paper.

Exploring the fluctuation of motivation and use of self-regulatory processes during learning with hypermedia

We collected think-aloud, pre-test, post-test, and motivation data from 43 undergraduates to examine the impact of conceptual scaffolds on the fluctuation of certain motivation constructs and use of self-regulatory processes during learning with hypermedia. Participants were randomly assigned to either the No Scaffolding (NS) or Conceptual Scaffolding (CS) condition. During the experimental session, each participant individually completed a pre-test on the circulatory system, a pre-task motivation questionnaire, one 30-min hypermedia learning task during which they learned about the circulatory system, a motivation questionnaire at three regular intervals during this learning task, a post-test on the circulatory system, and a post-task motivation questionnaire. Results indicated that while participants in both conditions gained declarative knowledge, participants who received conceptual scaffolds during learning demonstrated deeper understanding of the circulatory system on the post-test. In terms of self-regulatory processes, the results indicated that participants in the CS condition used significantly more planning processes during learning than participants in the NS condition. Additionally, participants in both conditions significantly decreased their use of strategies as they progressed through the learning task. Regarding motivation while learning with hypermedia, results indicated that participants in both conditions reported significantly increased levels of interest as they progressed through the learning task. Furthermore, participants in the CS condition reported the task as being easier and putting forth less effort than participants in the NS condition.

The effects of computer use in science and mathematics education upon the computer literacy of preservice elementary teachers

This study investigated the effects of computer use upon the computer literacy of preservice elementary teachers using two methods of instruction: computer assisted instruction in an earth science course and computer programming in a mathematics education course. Computer literacy was measured by the Minnesota Computer Literacy and Awareness Assessment (MCLAA). For each component of computer literacy, differences in group posttest scores were compared using an analysis of covariance with pretest scores used as the covariate. Pre- to posttest increases in scores for each group were also examined. The results indicated that the treatment given to the computer programming group had little or no effect upon the students' computer literacy, while the treatment given to the computer assisted instruction group had a significant effect upon the affective subscale of the MCLAA. A positive effect was also indicated on the cognitive subscale of the MCLAA. Thus, it appears that an effective method for improving preservice elementary teachers' computer literacy is to involve them in computer assisted instruction, possibly through a science course.

Pathways to literacy: a study of invented spelling and its role in learning to read

This intervention study tested whether invented spelling plays a causal role in learning to read. Three groups of kindergarten children (mean age = 5 years 7 months) participated in a 4-week intervention. Children in the invented-spelling group spelled words as best they could and received developmentally appropriate feedback. Children in the 2 comparison groups were trained in phonological awareness or drew pictures. Invented-spelling training benefited phonological and orthographic awareness and reading of words used in the intervention. Importantly, the invented-spelling group learned to read more words in a learn-to-read task than the other groups. The finding are in accord with the view that invented spelling coupled with feedback encourages an analytical approach and facilitates the integration of phonological and orthographic knowledge, hence facilitating the acquisition of reading.     

The effect of individual differences in the inner and outer states of ICT on engagement in online reading activities and PISA 2009 reading literacy: Exploring the relationship between the old and new reading literacy

With the prevalence of ICT, the concept of reading literacy has evolved to encompass both online reading and printed texts. This study clarifies the relationship between reading printed texts and online electronic texts from the perspective of individual differences in the inner and outer phases of ICT in a partial mediation model. We used the PISA 2009 data with 297,295 fifteen-year-old students (49.6% males) across 42 regions. The inner state of ICT represents students' attitude toward computers and confidence in high-level ICT tasks, whereas the outer state of ICT represents students' access to ICT facilities at home or school. The indirect results showed students' reading literacy improved with better attitude toward computers, confidence, and ICT availability at home, as long as the effect was mediated through engagement in online reading activities, even though availability of ICT at home had a direct and negative impact on PISA 2009 reading literacy.     

Professors' and students' conceptualizations of the learning task in introductory physics courses

What are students expected to learn in physics courses? Eight expert physics teachers and researchers, two from the University of Western Ontario in Canada, Cambridge University in the United Kingdom, Stanford University in the United States of America, and Monash University in Australia, described their perceptions of learning in their courses. Students from the courses were then interviewed for their perceptions of learning in physics courses. In their courses, professors focused on the development of intellectual skills, assuming that students had a specific physics vocabulary. Students, however, were aware of their own limitations and suggested that professors should take nothing for granted. Students considered that to be a good teacher, a professor should know the perspective of the students and should start at the students' level. The results suggested that the intellectual challenge of learning physics merits early explanation.     

Alternative approaches to the definition and identification of learning disabilities: Some questions and answers

Recent consensus reports concur in suggesting major changes in the federal regulatory approach to the identification of learning disabilities (LD). These reports recommend abandoning the IQ-discrepancy model and the use of IQ tests for identification, and also recommend incorporation of response to instruction (RTI) as one of the identification criteria. These changes are also recommended to states in the current reauthorization of the U.S. Individuals with Disabilities in Education Act (IDEA). While not mandatory, states that follow these recommendations will experience major changes in identification and treatment of students served under the LD category. This paper reviews the basis for these recommendations, summarizing four recent consensus group reports on special education that concur in suggesting these changes. Seventeen commonly asked questions about these changes are presented, with responses. In order to ensure adequate instruction for students with LD, it is essential that identification practices focus on assessments that are directly related to instruction, that any services for students who are struggling prioritize intervention over eligibility, and that special education be permitted to focus more on results and outcomes and less on eligibility and process. Identification models that incorporate RTI represent a shift in special education toward the goals of better achievement and behavioral outcomes for students identified with LD, as well as those students at risk for LD.

The feature-positive effect and sign-tracking behavior during discrimination learning in the rat

Feature-positive (FP) and feature-negative (FN) successive discrimination learning was investigated in the rat. When a discrete, visual element serving to differentiate the discriminanda belonged to S+ (FP), rats acquired the discrimination more rapidly than when it formed a part of S? (FN). During the course of training, FP rats developed a tendency to direct their responding toward the differentiating feature in S+ while FN rats shifted their responding away from this element in S?. These findings were discussed in terms of the conceptions of stimulus-reinforcer relations and “sign-tracking” behavior.     

Exploring the variety of parental talk during shared book reading and its contributions to preschool language and literacy: evidence from the Early Childhood Longitudinal Study-Birth Cohort

Although many studies have explored shared book reading between preschoolers and their families, very few have examined this practice within a large, nationally representative sample. Using the ECLS-B dataset, this study investigated shared reading among nearly 700 families of diverse ethnic, linguistic, and socioeconomic backgrounds. Coding of families’ book-related discussion focused on the variety of types of talk that parents used during reading. Results showed that parents focused primarily on the meaning of the story, with little attention to the code of the text. The range of talk techniques that parents used was largely independent of background factors such as child gender, ethnicity, or age, as well as family home language. A wider variety of meaning-related remarks by parents was linked to more advanced language skills among preschoolers. Findings provide a portrait of the nature of shared book reading discussion among American families, a profile of the background factors that are linked to this talk, and a precise account of the unique contributions of this talk to key emergent language and literacy competencies.     

Difficulties with consonants in the spelling and segmentation of CCVCC pseudowords: Differences among Dutch first graders

The goal of the present study was to explore the errors made by Dutch first graders in spelling syllable-initial and syllable-final consonants clusters in CCVCC pseudowords, to look for error types that discriminate poorer spellers from better spellers, and to relate these error types to the errors made when segmenting the same words. Such a correspondence across tasks would point to problems with the phonemic conceptualization of the spoken word as a source of spelling difficulty. The most prominent spelling error among poor spellers was omission of the consonant immediately following the vowel. This error seemed to be reflected in segmentation by omission of that consonant, but even more by the consonant being left unsegmented from the preceding vowel. The spelling and segmentation errors that we observed in Dutch are similar to those previously observed in English. The finding that such errors are made with a disproportionate frequency by poor spellers is new and suggests a basic problem in developing a phonemic conceptualization of spoken words (and of postvocalic consonant clusters in particular) that is adequate for spelling.     

Exploring the effects of online learning behaviors on short-term and long-term learning outcomes in flipped classrooms

ABSTRACT

The flipped classroom pedagogy has been widely used recently. Despite many researches have paid attention with the learning outcome of flipped classroom, there has been limited attention in regard to investigate the relationship between learning behavior and learning outcomes in a flipped classroom. In this paper, we proposed to investigate the influence of online learning behaviors on short-term and long-term learning outcomes in a flipped classroom. This study used Calculus and grade point average (GPA) scores to represent short-term and long-term learning outcomes, respectively. Multiple linear regression indicated that students’ online learning behavior does not have a significant effect on short-term learning outcomes, but has a significant effect on long-term learning outcomes. For applying multiple correspondence analysis, students were divided into groups according to five grade levels based on their scores. According to GPA grade level, students’ online learning behaviors had a significant effect on long-term learning outcomes for the five groups (GPAa, GPAb, GPAc, GPAd, GPAe). According to their Calculus grade level, students’ online learning behaviors had a significant effect on short-term learning outcomes for three groups (CALa, CALd, and CALe), but two groups (CALb and CALc) did not demonstrate this trend. For exploring the effects of online learning behaviors on future learning outcomes, GPA can be considered representative because the GPA was calculated for the entire academic year 2015. Students in the CALa group exhibited the highest frequency of online learning behaviors and obtained the highest GPA grade levels (GPAa and GPAb). For the CALb, CALc, CALd, and CALe groups, students with a higher frequency of online learning behaviors obtained a higher GPA grade level. These results indicate that students’ online learning behaviors have a positive effect on future learning outcomes.     

Instability in students' use of intuitive and Newtonian models to predict motion: the critical effect of the parameters involved

This study reports how children switch from intuitive to scientific models of explanation of motion when the numerical conditions in the presented problem are changed. Previous studies have suggested that student knowledge of mechanics may be compartmentalized: their everyday intuition serves in everyday contexts and their scientific model is activated, if ever, in academic contexts. In this study we investigate a case where significant numbers of students appear to draw on different models of motion in what is essentially the same, academic context, i.e. the prediction of the motion of a block on a smooth surface under the action of horizontal forces. Many students exhibit combinations of Aristotelian-like intuitions and Newtonian conceptions depending on the magnitudes of the quantities involved. The students' experience of being taught Newtonian theory in mathematics and physics has small but significant effects on the explanations they offer. The notion of anchoring and bridging is re-examined as a teaching strategy in such situtions.
