Using Technology-Enhanced Inquiry-Based Instruction to Foster the Development of Elementary Students’ Views on the Nature of Science

The Next Generation Science Standards support understanding of the nature of science as it is practiced and experienced in the real world through interconnected concepts to be imbedded within scientific practices and crosscutting concepts. This study explored how fourth and fifth grade elementary students’ views of nature of science change when they engage in a technology-enhanced, scientific inquiry-oriented curriculum that takes place across formal and informal settings. Results suggest that student engagement in technology-enhanced inquiry activities that occur in informal and formal settings when supported through explicit instruction focused on metacognitive and social knowledge construction can improve elementary students’ understanding of nature of science.

     

If they can speak,why can't they read? And spell? They may now!

For the dyslexic and others with similar problems, it is suggested that the sequence of modalities known as VAKT be revised to achieve more effective and more rapid remediation. The new sequence is designated as TAK/v. The subordination of the visual modality is based on the recent identification of a visual processing deficiency in dyslexics, as well as on previous hypotheses, suggesting the desirability of substituting the tactile modality for the visual modality in the initial stages of remediation. The use of one hand is suggested for this tactile scanning of three-dimensional letters to access the right hemisphere, and experimental data are reported.     

Challenges of Implementing Contract Policies for University Academics in Malawi: A Case of Mzuzu University

Utilising critical theory, we explored the causes of the conflict that arose between academic staff on fixed-term renewable contracts and university administrators at Mzuzu University in Malawi in order to draw lessons. We collected data using semi-structured, in-depth interviews and document analysis. Ten university employees were purposively selected for interviews. The results showed that the causes of the conflict were, in the view of the respondents a mixture of: 1) a mutually antagonistic relationship between academics and university administrators; 2) less-than-effective administration of contracts by the university leadership; 3) dispute with respect to the university council’s views over the age of staff on contract; and 4) the university leadership’s negative response to a group of academics who criticised the administration. We argue that these results suggest leadership skills were less-than-satisfactory on the part of university senior management. We offer suggestions that could improve such leadership skills.     

Flowery math: a case for heterodiscoursia in mathematics problems solving in recognition of students’ authorial agency

In an innovative, progressive school, students were asked to solve a fairly routine mathematical problem using real money in a “real-world” scenario. Even though the school values students’ ideas, the reaction of the teacher to one student’s alternative modelling of the problem suggests that he was expecting a particular answer to be provided using routine mathematical models and thinking while not being interested in exploring the student’s unexpected alternative. We place his reasoning for doing so within broad pedagogical discourses that we think define the “allowable” responses of teachers and students in ways that inhibit meaning-making for both. These broad discourses are defined as the progressive constructivist approach, the scaffolding discursive approach, the situation modelling approach and the dialogic approach. We consider the advantages and the potential consequences each might bring to the case. We suggest that extensive consideration of pedagogical discourses in mathematics classes must be reconsidered both for how we understand students’ mathematical meaning-making and how we construct student agency in relationship to culture, whether as apprentices or authors.     

Encouraging E‐Textbook Adoption: Merging Two Models

This research builds a new model by drawing upon e‐textbook adoption models developed in two recent publications, which share similarities but have different findings. Although they both achieve positive results, these two prior e‐textbook studies employ different methods and background theories. This research bridges these earlier models and develops a third, parsimonious, blended model for e‐textbook adoption. Using a survey of undergraduate students, the authors first assess each model independently. Broadening the diversity of the sample population yields results that are similar, yet slightly different from those found in the prior two studies. Next, this study develops a single blended, parsimonious model that explains a higher proportion of the variance than the prior studies with just three constructs: perceived usefulness, hedonic motivation, and habit. In addition to developing and testing a new parsimonious model, this research provides theoretical and practical guidance for e‐textbook usage.
