Assumptions and practices in using digital technologies to teach writing in middle‐level classrooms across Canada

Interviews with 216 Grades 4–8 teachers and observations in 21 classrooms show that computers are widely used to teach writing across Canada. Restricted access to computers plays a role in the frequency and types of interactions that students and teachers have with computers in writing classes. Equally influential are assumptions about writing development and effective teaching practice. Many participating teachers believe that spell checkers hamper students’ spelling development. They view computers as tools to extend and support their teaching of mini‐lessons.     

An Examination of How a Teacher's Use of Digital Tools Empowers and Constrains Language Arts Instruction

The Common Core State Standards produce a need to understand how digital tools can support literacy instruction. The purpose of this case study was to explore how a language arts teacher's integration of computers and iPads empowered and constrained her and the resulting classroom instruction. Constraining factors included (a) inadequate technological knowledge, (b) expectations of students’ comfort with technology, (c) inappropriate expectations for assignments, and (d) limited conceptions of the purposes of technology. Subthemes related to enhancement included: enhancement of classroom environment, simplicity and sophistication equal innovation and empowerment, combining tools, and digital tools support multimodal communication.     

Students' Choice for Computers

Nowadays,computers are widely used as useful tools for our daily life.So you can see students using computers everywhere.The purpose of our survey is to find out the answers to the following questions:1.What brand of computers do students often choose?2.What is the most important factor of choosing computers in students’idea?3.What do students want to do with computers most?After that,we hope the students will know what kind of computers they really need and how many factors must be thought about when buying computers.     

Abilities and affordances: factors influencing successful child–tablet communication

Using Luhmann’s communication theory and affordance theories, we develop a framework to examine how kindergarten-grade 2 students interact with tablet computers. We assessed whether cognitive ability and device configuration influence how successfully children use tablet computers. We found that children’s limited ability to direct their cognitive resources affects child–tablet communication (i.e., sending and receiving information to and from the device). While it may appear that children simply know how to use this technology, they are actually engaged in a systematic assessment of the device governed by their level of attentional maturity. Interestingly, tablet computers designed for adults result in a higher frequency of successful communication but prolonged communication was most likely to take place on child-focused tablet computers. It seems that communication success and user engagement are independent.

Instructional technology: A tool or a panacea?

It is time to recognize that educational technology cannot be considered a panacea for educational reform. Technology, when properly used, can be a very effective tool for improving and enhancing instruction and learning experiences in the content areas. However, incorporation of electronic tools, such as computers and videodiscs, into classrooms must be accompanied by systemic change in the educational process. Successful utilization of technology depends on how we provide teachers with the necessary environment for training, tools for instruction, and technology evaluation skills. This paper examines some of the misuses of technology and then explores the appropriate use of technology in the context of current educational reform. The focus is on the integration of technology in the educational process that provides a learning environment allowing discovery and creativity through the use of computer visualizations. The teacher is seen as the essential element, requiring a solid foundation in the general applications of technology, and the ability to evaluate and select systems that are effective and efficient for specific applications.

21st Century Paradigms for Pre-Service Teacher Technology Preparation

This study investigated major course changes in 11 sections of a stand-alone educational technology course redesigned around 21st century skill sets as opposed to technical skill development. Conducted in the fall of 2007 and spring 2008 with a random sample of 100 pre-service teachers, independent and paired sample t tests and correlational analyses were used to examine differences in students’ computer attitude, self-efficacy, and computer skills before and after instruction. Results of the study suggest that, even in a more rigorous course, pre-service teachers became less anxious about computers, their belief in the value of using technology to enhance teaching and learning as well as their self-efficacy toward integrating technology in the classroom significantly improved, and they became more advanced in their technical skills and knowledge of how to apply these skills in the classroom.
