Assessing Students’ Deep Conceptual Understanding in Physical Sciences: an Example on Sinking and Floating

This paper presents a transformative modeling framework that guides the development of assessment to measure students’ deep understanding in physical sciences. The framework emphasizes 3 types of connections that students need to make when learning physical sciences: (1) linking physical states, processes, and explanatory models, (2) integrating multiple explanatory models, and (3) connecting scientific models to concrete experiences. We carried out a 2-phase exploratory study that helped further develop and refine the framework. In the first phase, we developed 3 items on sinking and floating and pilot tested them with 18 undergraduate students. Analysis of student responses revealed various student misconceptions and the different connections students made among science ideas. Based on the findings, we revised the assessment, modified the instruction, and collected data from another cohort of 26 students. The second cohort of students showed significant improvement of understanding of sinking and floating after instruction. Implications and limitations of how our assessment framework can be used to improve students’ conceptual understanding in science are discussed.     

Using the theory of planned behaviour framework to understand Tasmanian dairy farmer engagement with extension activities to inform future delivery

Purpose: To identify and understand factors influencing farmers’ decisions to engage with extension activities. To understand farmer segments and how these factors vary in order to develop recommendations for future extension delivery.

Methodology: Qualitative data was obtained through semi-structured interviews with 30 Tasmanian dairy farmers. The Theory of Planned Behaviour (TPB) framework was used to identify and explore factors influencing farmer engagement intentions and behaviour.

Findings: There was a negative effect of social influence on experienced farmers’ intention to re-engage with extension, due to the belief extension activities were targeted to less experienced, younger farmers. Perceived control factors limiting engagement included lack of confidence about existing knowledge, resulting in farmers perceiving extension activities as confronting.

Practical implications: Key factors influencing intention to engage and continued engagement with extension were identified. These findings will inform future design and targeting of extension activities to improve initial and continued engagement. Subsequent recommendations are presented.

Theoretical implications: Previous TPB studies on adoption as an outcome of extension have typically focused on quantifying adoption predictions, rather than exploring how social factors interact and influence intentions and behaviours. This paper demonstrates how the TPB can be qualitatively applied to better understand farmer decision making, in this instance with respect to their initial and continued engagement with extension.

Originality/value: This paper demonstrates how the TPB can provide an evidence-based framework to qualitatively explore farmer intentions and behaviour. This approach has led to new insights into farmer decision making that will inform improvements in future extension development.

Automated Scoring of Constructed‐Response Science Items: Prospects and Obstacles

Content‐based automated scoring has been applied in a variety of science domains. However, many prior applications involved simplified scoring rubrics without considering rubrics representing multiple levels of understanding. This study tested a concept‐based scoring tool for content‐based scoring, c‐rater?, for four science items with rubrics aiming to differentiate among multiple levels of understanding. The items showed moderate to good agreement with human scores. The findings suggest that automated scoring has the potential to score constructed‐response items with complex scoring rubrics, but in its current design cannot replace human raters. This article discusses sources of disagreement and factors that could potentially improve the accuracy of concept‐based automated scoring.     

Neural Correlates of Performance Monitoring During the Transition to Young Adulthood

Cognitive challenges during transition to adulthood are generally high and require particular skills, such as self‐control, performance evaluation, and behavioral adjustment for success in everyday living. However, age and sex differences in timing and efficiency of brain maturational processes in the early twenties are not well known. We used a go/no‐go paradigm and fMRI to focus on the neural processes underlying response inhibition and performance monitoring during the transition from late adolescence (aged 18–19) to young adulthood (aged 23–25). During performance monitoring, late adolescents showed more activation in right inferior frontal gyrus than young adults, while males showed more activation in left inferior parietal lobe than females. No effects of age and sex were found for response inhibition. Our findings suggest that age and sex‐related differences in neural basis of performance monitoring continue to change between late adolescence and young adulthood.     

Faculty and Technology: Implications for Faculty Training and Technology Leadership

The purpose of this study was to explore the factors affecting ICT adoption process and the implications for faculty training and technology leadership. Respondents represented a wide range of academic and professional positions. They identified themselves as Assistant, Associate, and Professor as well as Instructional Designer, Director of Technology, Information Manager, eLearning Manager, Assistant Department Chair, Associate Vice President of Academic Affairs and Consultant. The respondents identified Organizational Support, Leadership, Training and Development, and Resources as the predominate themes affecting Information and Communication Technology (ICT) adoption process in higher education. Evidence from this study offers insights on how higher education administrators and technology leaders could help their faculty and staff to implement appropriate ICT tools and practices to improve student learning.     

An investigation of teacher impact on student inquiry science performance using a hierarchical linear model

Teachers play a central role in inquiry science classrooms. In this study, we investigate how seven teacher variables (i.e., gender, experience, perceived importance of inquiry and traditional teaching, workshop attendance, partner teacher, use of technology) affect student knowledge integration understanding of science topics drawing on previous research. Using a two‐level hierarchical linear model, we analyze year‐end knowledge integration performance of 4,513 students taught by 40 teachers across five states. Results indicate that students of teachers who value inquiry teaching strategies have significantly higher levels of knowledge integration understanding than those of teachers who believe in traditional teaching methods. In addition, workshop attendance and having a partner teacher teaching the same unit in the same school also have a positive impact on students' knowledge integration levels. The results underscore the importance of professional development and collegial support in enhancing student success in inquiry science. © 2009 Wiley Periodicals, Inc.

‘Madam,are you one of them?’ ‘Reflexivities of discomfort’ in researching an ‘illicit’ subject

Informed largely by Affect theory (2004), this paper takes up ‘reflexivities of discomfort’ to reflexively engage with my affective struggles as a Christian, heterosexual, mother, educator, undertaking a study on homosexuality, which is a thorny issue in Uganda. It a methodological prologue, reflecting my thoughts and struggles before I undertake the study. My purpose is not to find solutions, but to lay bare some anxieties and ambivalences, also suggesting the limits of reflexivity. The paper begins with an autobiographical narrative about school in relation to (homo)sexuality. This is followed by an exposition of Uganda’s Anti-homosexuality Bill; my use of reflexivity and affect to inform my affective struggles; my background as it relates to sexuality, providing insights into my researcher positionality. I then engage with moments imbued with high affective/emotive intensity in my preparation to undertake the study.     

Student Evaluation of Instruction: In the New Paradigm of Distance Education

Distance education has experienced soaring development over the last decade. With millions of students in higher education enrolling in distance education, it becomes critically important to understand student learning and experiences with online education. Based on a large sample of 11,351 students taught by 1,522 instructors from 29 colleges and universities, this study investigates the factors that impact student evaluation of instruction in distance education, using a two-level hierarchical model. Key findings reveal that in a distance education setting, gender and class size are no longer significant predictors of quality of instruction. However, factors such as reasons for taking the course, student class status and instructor’s academic rank have a significant impact on student evaluation of learning and instruction. Findings from this study offer important implications for institutional administrators on utilizing the evaluation results and on developing strategies to help faculty become effective online instructors.     

Literacy Teachers Engage in Service-Learning via Community Organization Involvement

Service-learning provides community service as well as authentic, curriculum-driven learning experiences (Furco &; Root, 2010 Furco, A. and Root, S. 2010. Research demonstrates the value of service-learning. Kappan, 91(5): 16–23. [Web of Science ®] , [Google Scholar]) and has been an effective component of teacher education courses (García, Arias, Murri, &; Surna, 2010 García, E., Arias, M. B., Murri, N. J.
