Numerous educational research studies have shown that students perceptions of teacher-interpersonal behaviour and classroom environment are positively associated with students attitude to science and students cognitive achievement in science. Laptop computers have become increasing popular in science classrooms since the late 1980s; however, their effects on students perceptions of teacher interpersonal relationships or classroom environment have not been studied.The aim of this study was to assess the effectiveness of laptop computers in science classrooms, in terms of the effects laptops had on students perceptions of teacher-student interpersonal behaviour and classroom environment. Students attitude to science and their cognitive achievement in science were also assessed.Student data were collected from 433 grades 8 and 9 science laptop students in 23 classrooms, in 14 Independent schools, in four Australian states. Both quantitative and qualitative data were collected.The study confirmed the reliability and validity of the QTI and ICEQ for use in science laptop classrooms, described students perceptions of teacher-student interpersonal behaviour and classroom environment in science laptop classrooms and identified associations between students perceptions of teacher-student interpersonal behaviour and classroom environment with each of the student outcomes. The attitudinal outcomes were found to be more strongly associated with both perceptual areas, than were the cognitive achievement outcomes.The study also found that there was a difference in the way science laptop and non-laptop students perceived teacher-student interpersonal behaviour and classroom environment, but that there was no significant difference I the attitudinal and cognitive achievement outcomes between science laptop and non-laptop students.

This study investigated the relationship between four models of student laptop computer use and three components of teacher instructional behavior: planning, implementation of instruction, and evaluation of instruction. The four models of use: full access, dispersed, class set, and mixed, represented the numerous ways teachers in public and private schools and school districts nationwide implemented student use of laptop computers. Teacher planning behavior was investigated with regard to time, frequency, complexity, difficulty, the need for revision, and use of technological resources and materials. Implementation of instruction was examined with regard to student grouping, instructional strategies, instructional content/subject matter, teacher and student roles, assignments and learning tasks, and instructional activities. The evaluation of instruction component was examined with regard to assessment tasks, grading, and assessment of homework. Using a researcher-designed questionnaire, data was gathered in a single-stage cross-sectional survey from 356 teachers working in 74 public and private schools nationwide. Results indicated models of student laptop computer use had differential effects on teacher instructional behaviors. On average, teachers found planning to be more arduous, but more collegial, especially in the mixed model. The full access and mixed models were more likely to advance a constructivist approach to teacher instructional behaviors with regard to implementation and evaluation of instruction. Results from this study had implications for future research. The effects of student laptop computer use on the full access and mixed models of use should be given further study with regard to the implementation and evaluation of instruction.

This study analyzed the eighth grade mathematics portion of the spring 2004 Maine Educational Assessment (MEA) achievement test and the survey questions that were also administered. The analysis was on a school-wide level (n = 182). The two survey questions used were: “Which statement best describes the use of calculators in your mathematics classes?” and "Which statement best describes how you use your laptop in mathematics class: getting data from the Web, finding mathematics problems online, creating graphs?" Correlational analysis, partial correlation, and regression were used to determine if there was any association between calculator usage, laptop usage, and mathematics achievement for girls and for boys in the first state-wide group of students to have one-to-one laptops in Maine. Calculator usage was found to be positively associated with mathematics achievement for both girls (partial correlation coefficient of .189 (p = .011)) and for boys (partial correlation coefficient of .193 (p = .010)) even after controlling for school size and socio-economic status. Though no significant association between laptop usage and mathematics achievement for either girls or boys was found, this may be more a reflection on the survey question being a weak measure than the usage of laptops. In a post-hoc analysis of findings, schools were rank ordered based on the average mathematics achievement score regardless of gender; the top 25% (n = 45) and the lower 25% (n = 45) of the schools were evaluated. In the top 25%, there was no statistically significant difference between school-wide girls' and boys' mathematics achievement scores. However, in the lower 25% of the schools, there was a statistically significant difference (p = .01) between the school-wide average of girls' and boys' mathematics achievement scores, with the girls' score being 1.49 points higher (p = .01, d = .447) than the boys'. Recommendations for refinement of MEA survey questions as well as future studies are provided.
