The performance of college students on piaget-type tasks dealing with distance,time, and speed

Research was done to probe and extend Piaget's theory of the conception of speed. Specifically tested was the hypothesis that there is no hierarchical relationship in performance on the following Piaget-type tasks: conservation of distance, asymmetric series of speeds, one-to-many (circular) speeds, symmetric speeds, time, and proportional reasoning. The research also tested the gender-related performance on these six tasks. One hundred freshman and sophomore college students were shown demonstrations of equipment individually for each of the six tasks. A set of open-ended questions based on the demonstrations was administered to each subject in a 45-minute interview. Subjects were scored as “pass” on a given task if they manipulated objects in certain ways and gave specific types of explanations. A scalogram analysis of the data yielded a z-score of — 3.7 which indicated that subjects passed the task in a certain sequence. The tasks were found to form a unidimensional scale and to be increasingly difficult in the order listed above. A chi-square test for two independent samples showed a significant difference (alpha = 0.05) in performance between males and females on all speed tasks. No significant differences in performance between males and females were found for the distance and time tasks.     

Sustaining affective resonance: Co-constructing care in a school-based digital design studio

Based on two years of ethnographic engagement in a school-based digital design studio in a high school on the West Side of Chicago, Illinois, this paper conceptualizes the development and maintenance of an ethos of care in teaching and learning through sustaining affective resonance. Adopting musical metaphors as a vocabulary for affective movements, we operationalize practical and practiced methods for sustaining (actively extending) affective (care-giving and care-taking intensities) resonance (shared meaning making and cultural production). Sharing examples across years, we show the specific ways that mentors and students in the digital design studio built and nurtured care-full practices. The purpose of the paper is to explicate the development and enactment of mentoring practices that we observed in the design studio and then to consider how these practices might be shared, spread, and adapted across contexts of teaching and learning.     

Decolonising the reading of Aboriginal and Torres Strait Islander writing: reflection as transformative practice

ABSTRACT

First Nations writing within English literary studies risks contemporary colonisation if encountered as a literary object for close reading without context or reflection on the role of the reader. This article will explore the processes involved in constructing an innovative reading practice amongst tertiary students to counter the potential for intentional or unintentional colonial readings. Dr Sandra Phillips, First Nations academic and researcher, initiated and applied the reading practice (which overtly incorporates student/reader standpoint and then reflection on the impact of that standpoint among other considerations) from her PhD scholarship then applied it to her curriculum design of ‘Reading Aboriginal and Torres Strait Islander Writing’, which forms the basis of this research. Dr Clare Archer-Lean continued the coordination and teaching of the curriculum at the University of the Sunshine Coast in Queensland after Sandra moved tertiary institutions. The two academics continue to collaborate on the curriculum review and reflect on the processes of teaching and crafting this form of reading practice and assessment. Their aim has been to create a reading practice that accounts for the position and influence of the reader in the cross-cultural, or co-cultural, reading process. This is primarily achieved by acknowledging the role and influence of standpoint in the reading process as well as deepening reading through an understanding of the cultural, social and political discourses affecting the production, distribution and reception of First Nations writing in the Australian context.     

Teaching the business of instructional technology:A collaborative corporate/academic partnership

Conclusion The partnership that Bloomsburg University’s Institute for Interactive Technologies and Department of Instructional Technology have created with its CAC members provides current students with a rich and rewarding experience. The students are provided opportunities to hear from professionals in the field and are given the experience of preparing a realistic proposal, prototype and presentation. Their experience, in turn, prepares them to become contributing members in corporations as soon as they are hired. In fact, Nancy and her team from Workforce Interactive did an excellent job with their presentation. Nancy received many job many offers with various CAC member companies. She eventually took a position and has started a career as an instructional technologist. Almost immediately, she was made project manger of a major web-based training initiative. Now that her experience presenting to the CAC is finally over and she is gainfully employed, she can’t wait to return to Bloomsburg. Only this time, Nancy will be sitting on the other side of the table and armed with questions she has already been asked by clients.     

Aligning goals, assessments, and activities: an approach to teaching PCR and gel electrophoresis

Polymerase chain reaction (PCR) and gel electrophoresis have become common techniques used in undergraduate molecular and cell biology labs. Although students enjoy learning these techniques, they often cannot fully comprehend and analyze the outcomes of their experiments because of a disconnect between concepts taught in lecture and experiments done in lab. Here we report the development and implementation of novel exercises that integrate the biological concepts of DNA structure and replication with the techniques of PCR and gel electrophoresis. Learning goals were defined based on concepts taught throughout the cell biology lab course and learning objectives specific to the PCR and gel electrophoresis lab. Exercises developed to promote critical thinking and target the underlying concepts of PCR, primer design, gel analysis, and troubleshooting were incorporated into an existing lab unit based on the detection of genetically modified organisms. Evaluative assessments for each exercise were aligned with the learning goals and used to measure student learning achievements. Our analysis found that the exercises were effective in enhancing student understanding of these concepts as shown by student performance across all learning goals. The new materials were particularly helpful in acquiring relevant knowledge, fostering critical-thinking skills, and uncovering prevalent misconceptions.     

A self-advocacy plan for high school students with learning disabilities: a comparative case study analysis of students', teachers', and parents' perceptions of program effects

This qualitative study examined immediate perceived effects of a self-advocacy plan for students with learning disabilities (LD) in a 4-year comprehensive high school. The study's design was based on information-processing theory and qualitative research techniques, such as participant/observation and interviews. Subjects were 15 ninth- and tenth-grade students with LD, their parents, and their resource teachers. Participants responded to standardized open-ended interview questions upon completing the first step of the Self-Advocacy Plan. The study suggests that the Self-Advocacy Plan is an effective program increasing students' awareness of the vocational and academic services they qualify for, clarifying their perceptions of their roles as learners and individuals with LD, increasing their understanding of LD as a condition that has certain general characteristics, and developing their awareness of career and educational opportunities. The study provides suggestions for future self-advocacy research and for special educators who wish to design programs for students with LD incorporating the concepts of psychosocial development of the individual, information-processing theory, and self-advocacy.     

An investigation of the relationship between logical thinking structures and the ability to construct and interpret line graphs

This study investigates the relationship between logical thinking structures and the ability to construct and interpret line graphs. Seventy-two subjects in 7th, 9th, and 11th grades were administered individual Piagetian tasks to assess five specific mental structures: (Euclidean spatial structures) (a) Placement and Displacement of Objects (maintaining horizontal and vertical reference frames) and (b) One–One Multiplication of Placement and Displacement Relations (coordinate systems); (c) Multiplicative Measurement; (d) Multiplicative Seriation; and (e) Proportional Reasoning. Graphing abilities were assessed by having the subjects construct and interpret numerous graphs of varying content and difficulty. To minimize the researcher's guesses about interpretation, each subject's answers and reasons were subsequently explored during a clinical interview. The results indicate significant relationships of logical thinking to graphing ability. Multiplicative seriation, multiplicative measurement, and Euclidean spatial structures positively influenced graphing abilities. Subjects who showed evidence of proportional reasoning did significantly better on many graphing situations including choosing the part of the graph with the greatest “rate of change.” Locating points on a graph without a grid was significantly related to horizontal/vertical frames of reference. Students who did not possess the logical thinking structures were more likely to be dependent upon, and influenced by, perceptual cues and less able to interpret or construct graphs correctly.     

Student and recent graduate perspectives on radiological imaging instruction during basic anatomy courses

Recently, faculty at Pritzker School of Medicine, The University of Chicago, have made efforts to improve the depth of radiological anatomy knowledge that students have, but no insights exist as to student and resident opinions of how clinically helpful deep anatomical understanding is. A single‐institution survey of second‐ and fourth‐year medical students and postgraduate year 1–4 residents from 11 specialties, composed of five‐point Likert questions, sample examination questions, and narrative response questions, was distributed in 2015. One hundred seventy‐seven of the 466 potential respondents replied (71 residents and 106 students), response rate 38.0%. No nonresponse bias was present in two separate analyses. Respondents generally favored a superficial “identification” question as more relevant to clinical practice, which was positively associated with increasing clinical experience ρ = 0.357, P < 0.001 by point‐biserial correlation. Students and residents most commonly used self‐directed methods to learn medical imaging during their medical anatomy courses (72.6 and 57.7%, respectively). Small group education was least commonly used by students and residents (45.3 and 39.4%, respectively), but most commonly recommended (62.3 and 69%, respectively). A total of 56.6 and 64.8% of students and residents, respectively, reported that having multiple learning methods was “quite” or “extremely” important. Respondents with more clinical experience were more likely to report that a superficial identification question was more clinically relevant than a question testing deeper radiological anatomy knowledge. Small group learning was preferred among students and residents but was the least commonly employed method of instruction. Both findings contrast starkly with current radiological anatomy instructional understanding and practices. Anat Sci Educ 11: 25–31. © 2017 American Association of Anatomists.     

Re-contextualising TPACK: exploring teachers’ (non-)use of digital technologies

Technological, pedagogical and content knowledge (TPACK) has been used by hundreds of studies as a theoretical framework to explore teachers’ technology use in classroom settings. While these studies have contributed to understandings of the interplay between these different knowledge domains and the differences between pre- and in-service teachers’ knowledge, little work has been done to examine the influence of teachers’ socially mediated workplace settings on TPACK enactment. This article begins to address this issue reporting findings from an eight-month case study involving 10 teachers in an Australian secondary school. Results reported in this article indicate that TPACK enactment is influenced by processes of identity development and practice. These findings challenge the established position of knowledge as an epistemological possession inherent in the TPACK framework rather than also considering knowing as an epistemology of practice. Implications for in-service teachers and school authorities are discussed and suggestions for future research considered.
