Levels of students’ “conception” of fractions

In this paper, we examine sixth grade students’ degree of conceptualization of fractions. A specially developed test aimed to measure students’ understanding of fractions along the three stages proposed by Sfard (1991) was administered to 321 sixth grade students. The Rasch model was applied to specify the reliability of the test across the sample and cluster analysis to locate groups by facility level. The analysis revealed six such levels. The characteristics of each level were specified according to Sfard’s framework and the results of the fraction test. Based on our findings, we draw implications for the learning and teaching of fractions and provide suggestions for future research.     

The influence of multiperspectivity in history texts on students’ representations of a historical event

School history textbook narratives of a nation’s past often present limited perspectives, which may impede the aim of teaching history from multiple perspectives. Less is known about the influence of including multiple perspectives on students’ representations of the past. This study examines the extent to which students include multiple perspectives when processing a schoolbook text that includes multiple perspectives compared to a schoolbook history text containing fewer perspectives. Tenth grade students (N = 104) in four schools were randomly assigned to read one of two texts on the Dutch Revolt and asked to make a summary. Multiperspectivity was analysed through the representation of actors, aspects of scale, dimensions and historiography. The students working with the text having high multiperspectivity showed more perspectives in their representations. In the summaries, these students included significantly more perspectives than did the students using the text with fewer perspectives. Moreover, these students’ representations of the main actors were more nuanced. The students using the text with high multiperspectivity situated the conflict in a broader international context and integrated more historiographical dimensions. The insights generated by these outcomes emphasize the important role of textbooks when aiming to teach history from multiple perspectives.

     

Holding the severed finger: Korean students’ understanding of historical significance

This study investigated students’ ideas about historical significance in Korea. Using qualitative, task-based interviews, I interviewed 28 secondary students who had taken Korean and world history courses. In response to various historical contexts, these Korean students relied primarily on a schematic narrative template consisting of ‘tragedy,’ ‘struggle,’ and ‘freedom and equality’ to judge historical significance. This schematic narrative template reflected the national identity which Korea established in the postcolonial context after independence in 1945. By applying this template to world history, moreover, students showed strong sympathy towards the oppressed, and this reflected their resistance to colonial and class hegemony. However, imposing this template resulted in significant omissions and distortions that might hinder the development of critical historical thinking. These findings suggest that a variety of cultural tools are necessary for Korean students to develop more complete and nuanced historical understanding.     

In the eyes of the beholder: students’ and teachers’ judgments of students’ motivation

This study was designed to examine the nature and accuracy of teachers’ judgments about students’ motivation related to mathematics. Seventeen fourth- through sixth-grade teachers and 100 of their students participated in this study. Teachers were asked to rate six target students’ motivation four times during the school year. At each of these times students also rated their own motivation. Teachers’ ratings were more stable over time and across mathematics topics and were less differentiated across motivation dimensions than were students’ ratings. The findings suggest that teachers need to pay careful attention to evidence related to children's motivation that might contradict their perceptions and therefore support more effective interventions.

Peer feedback on college students’ writing: exploring the relation between students’ ability match,feedback quality and essay performance

There does not appear to be consensus on how to optimally match students during the peer feedback process: with same-ability peers (homogeneously) or different-ability peers (heterogeneously). In fact, there appears to be no empirical evidence that either homogeneous or heterogeneous student matching has any direct effect on writing performance. The current study addressed this issue in the context of an academic writing task. Adopting a quasi-experimental design, 94 undergraduate students were matched in 47 homogeneous or heterogeneous reciprocal dyads, and provided anonymous, formative peer feedback on each other’s draft essays. The relations between students’ individual ability or dyad composition, feedback quality and writing performance were investigated. Neither individual ability nor dyad composition directly related to writing performance. Also, feedback quality did not depend on students’ individual ability or dyad composition, although trends in the data suggest that high-ability reviewers provided more content-related feedback. Finally, peer feedback quality was not related to writing performance, and authors of varying ability levels benefited to a similar extent from peer feedback on different aspects of the text. The results are discussed in relation to their implications for the instructional design of academic writing assignments that incorporate peer feedback.     

The effects of browse time on the Internet on students’ essay scores

This study examined how 30 minutes of search time on the Web affected students’ essay scores in response to a writing prompt. Expository essays were obtained from 49 fourth- and fifthgrade students enrolled in an elementary school in Virginia, in the United States. Students were placed by random assignment into three groups with the same writing prompt for all three groups. Data analyses using ANOVA indicate that there was statistical significance in two components of writing. The group that received instruction on using the Internet to conduct research in the prewriting phase outperformed the control group in two areas: the total essay score (p=.053) and usage/mechanics (p=.028). The study also produced effect sizes ranging from small to large when the Internet users were compared to the control group. Implications for the future of Internet use in the school system are discussed.     

The relation between students’ motivational beliefs and their use of motivational regulation strategies

The goal of this study was to investigate the relation between a set of pre-decisional beliefs including students’ task value, self-efficacy, and learning and performance goal orientations and five post-decisional, implementation strategies students use to regulate their effort and persistence for the academic tasks assigned for a specific class. A group of eighth grade students (N=114) completed a self-report survey that assessed these four motivational beliefs and the frequency that they used five motivational regulation strategies including self-consequating, environmental control, interest enhancement, and mastery and performance self-talk. Results from a series of multiple regressions indicated that the motivational beliefs, as a group, could be used to explain students’ reported use of each of the regulatory strategies examined. Further, results indicated that task value, learning goal orientation, and performance goal orientation individually explained three or more of the regulatory strategies, whereas self-efficacy was not related significantly to any of the five regulatory strategies studied. Findings are presented and interpreted in light of their significance for models specifying both motivational and volitional aspects of self-regulation.     

The structure of students’ beliefs about the use of representations and their performance on the learning of fractions

Cognitive development of any concept is related with affective development. The present study investigates students’ beliefs about the use of different types of representation in understanding the concept of fractions and their self‐efficacy beliefs about their ability to transfer information between different types of representation, in relation to their performance on understanding the concept. Data were collected from 1701 students in Grade Five to Grade Eight. Results revealed that multiple‐representation flexibility, ability on solving problems with various modes of representation, beliefs about the use of representations and self‐efficacy beliefs about using them constructed an integrated model with strong interrelations in the different educational levels. Confirmatory factor analysis affirmed the existence of differential effects of multiple‐representation flexibility and problem‐solving ability in respect to cognitive performance and the existence of general beliefs and self‐efficacy beliefs about the use and the role of representations. Results suggested the invariance of this structure across primary (Grades Five and Six) and secondary education (Grades Seven and Eight). However, there are interesting differences concerning the interrelations among those cognitive and affective factors between primary and secondary education.     

The effect of prior education on students’ competency in digital logic: the case of ultraorthodox Jewish students

In line with the growing interest in extending the diversity of CS students, we examined the performance of a unique group of students studying an introductory course in Digital logic: ultraorthodox Jewish men, whose previous education was based mostly on studying Talmud and who lacked a conventional high-school education. We used questions from the Digital Logic Concept Inventory . We compared the results to those of religious Jewish men with a conventional high-school education, and to the results reported in the literature. The ultraorthodox group performed better than the other groups in tasks that concerned number representation. No other statistically significant differences were found. Talk-aloud protocols revealed that the ultraorthodox students utilized a viable conceptual understanding in their performance. We can conclude that students’ unique, alternative prior education should not be merely viewed as an obstacle to their academic studies, but also as a potential source for strengths.     

The effect of culture and belief systems on students’ academic buoyancy

Increasingly, learner motivation is implicated in student failure at universities. This has led to intense research into internal or external variables that might buoy resilience to failure. This research investigates the impact of strong cultural connectedness and strong belief systems on the academic buoyancy of international students studying at an Australian University. For this purpose, we surveyed 102 tertiary students at a Sydney university. Results demonstrate that, in the event of academic failure, students’ academic buoyancy remains high if they have support through strong cultural connections and from their belief systems. We further endeavored to identify if academic buoyancy was fed by intrinsic or extrinsic motivation. This research contributes to the understanding of the sources of strengths available to international students from primarily collective cultures studying overseas. There are implications for educational practice in terms of identifying students ‘at high risk’ if they are unable to draw strengths from cultural connections and belief systems.     

The influence of parents on undergraduate and graduate students’ entering the STEM disciplines and STEM careers

This research examines the influence of parents on students’ studying the STEM disciplines and entering STEM careers. Cases of two graduate students (one female, one male) and one undergraduate student (male) are featured. The first two students in the convenience sample are biology and physics majors in a STEM teacher education programme; the third is enrolled in computer science. The narrative inquiry research method is used to elucidate the students’ academic trajectories. Incidents of circumstantial and planned parent curriculum making surfaced when the data was serially interpreted. Other themes included: (1) relationships between (student) learners and (teacher) parents, (2) invitations to inquiry, (3) modes of inquiry, (4) the improbability of certainty, and (5) changed narratives?=?changed lives. While policy briefs provide sweeping statements about parents’ positive effects on their children, narrative inquiries such as this one illuminate parents’ inquiry moves within home environments. These actions became retrospectively revealed in their adult children’s lived narratives. Nurtured by their mothers and/or fathers, students enter STEM disciplines and STEM-related careers through multiple pathways in addition to the anticipated pipeline.     

Does students’ heritage matter in their performance on and perceptions of historical reasoning tasks?

This mixed methods study explores how high school students (N = 35) enrolled in a US charter school with a high Latino/a population perform on and perceive (in terms of interest and relevance) document-based type historical reasoning tasks: one about the Dust Bowl in the 1930s and the other about the experiences of Mexicans and Mexican Americans in the 1920s. Students wrote essay responses and completed perception inventories about the tasks. We also interviewed 10 focal students to delve more deeply into students’ thinking regarding the tasks and their interest levels in the two topics. We scored students’ responses along the criteria of historical claims, substantiation of claims, use of evidence from documents, sourcing of documents and contextualization. Our hypotheses were that students would perform better on, and be more interested in, tasks that were culturally relevant to them. We found that although students did not perform differently on the two tasks overall, students’ perceptions of the tasks differed, with a significantly greater interest in the task about Mexicans and Mexican Americans. We address the complexity of these findings and discuss implications for curriculum and practise.     

The influence of students’ interest,ability and personal situation on students’ perception of a problem-based learning environment

The twofold purpose of this study is to identify engineering students’ perceptions of a problem-based learning environment and to analyse the influence of their personal situation, general interest in engineering and ability to succeed on their perception, after they were exposed to PBL for the first time. Based on an adjusted version of the problem-based learning environment inventory [Senocak, E. 2009. “Development of an Instrument for Assessing Undergraduate Science Students’ Perceptions: The Problem-based Learning Environment Inventory.” Journal of Science Education Technology 18 (6): 560–569], data regarding students’ perception were collected through a questionnaire survey and analysed by applying exploratory factor analysis and structural equation modelling. The analysis revealed a three-factorial PBL environment consisting of learning facilitator support, student responsibility and project quality, with strong influences of students’ personal situation on project quality, interest on the learning facilitator support and ability to succeed on students’ responsibility. Supporting students’ general interest in engineering seems to improve their perception of the learning facilitator support and ensuring students’ ability to succeed in a PBL environment seems to increase students’ awareness of their own responsibility.     

The effect of the planet’s number on dynamic characteristics of planetary gear systems

Considering the effect of planet’s number on the dynamic characteristics of the planetary gear system, a translation-torsion lumped-parameter model of 2K-H spur planetary gear system was established. Through the analysis of numerical solution, the results show that 1) When the planet’s number is more than 3, the order of the natural frequency will become the same; 2) When the planet’s number increases, the natural frequencies of planet mode remain invariant, but when it comes to rotational mode and translational mode, the higher order natural frequencies increase and the lower order natural frequencies decrease; 3) The planet’s number has a great impact on the higher order natural frequencies and a little impact on the lower order natural frequencies; and 4) To avoid the resonance, we can appropriately increase or decrease the number of the planet.

The influence of school type and perceived teaching style on students’ creativity

School is an excellent place to foster young learners’ creative thinking skills. However, the emphasis on creativity varies among schools. In two studies the putative influence of school education on the development of students’ creativity was examined by means of a retrospective approach. We investigated whether two influential factors within school education (1) school type (i.e., traditional vs. alternative vs. religious) and (2) perceived teaching style (i.e., independence, judgment, flexibility, integration) associate with students’ creativity at university entrance level. The difference was examined at the primary and secondary school level, respectively. Study 1a found that students who attended alternative schools at the secondary school level performed better on divergent thinking tasks as compared to students who attended traditional or religious schools. Relationship between students’ creative performance and the perceived teaching styles were inconclusive. Finally, teaching styles in alternative schools during secondary education were perceived as high in independence and flexibility. Study 1b replicated the finding that university students who attended alternative schools during secondary education have an advantage in divergent thinking. Taken together, our results highlight the positive influence of alternative school education on students’ creative performance at the university entrance level.
