The Effectiveness of the Geospatial Curriculum Approach on Urban Middle-Level Students’ Climate Change Understandings

Climate change science is a challenging topic for student learning. This quantitative study examined the effectiveness of a geospatial curriculum approach to promote climate change science understandings in an urban school district with eighth-grade students and investigated whether teacher- and student-level factors accounted for students’ climate change knowledge achievement. The participants included 12 science teachers and 956 eighth-grade students. Data included a pre- and posttest climate change assessment measures for both teachers and students and a teacher measure of Geospatial Science-Technological Pedagogical Content Knowledge. Paired-sample t tests revealed statistically significant gains from pretest to posttest on their climate change knowledge (p < .001; effect sizes being large on multiple-choice items and medium on the open-ended response assessment). Both ordinary least squares (OLS) multiple regression and 2-level hierarchical linear modeling found that students’ initial climate change knowledge and gender were significant predictors for students’ posttest scores, p < .05. Students’ pretest scores were the strongest significant predictor of the posttest scores, p < .001. Neither the teachers’ climate change knowledge nor their Geospatial Science-Technological Pedagogical Content Knowledge had significant association with the students’ posttest scores. Teaching years was a significant predictor for students’ posttest scores in OLS regression (p < .001). The findings provide support that a geospatial curriculum approach is an effective science curriculum approach for learners in urban middle-level education.

Analysis of reference transactions using packaged computer programs.

Motivated by a continuing education class attended by the authors on the measurement of reference desk activities, the reference department at Scott Memorial Library initiated a project to gather data on reference desk transactions and to analyze the data by using packaged computer programs. The programs utilized for the project were SPSS (Statistical Package for the Social Sciences) and SAS (Statistical Analysis System). The planning, implementation and development of the project are described.     

The role of value orientations in curricular decision making: a rationale for teachers' goals and expectations.

This research examined the role of value orientations in curricular decision making from the perspective of high school physical education teachers and students. Educational value orientations served as the theoretical base for the research. Teachers who exhibited one of two paired orientations, disciplinary mastery/learning process (DM/LP) or ecological integration/social reconstruction (EI/SR), were interviewed to examine the extent to which their value orientations influenced their stated (a) goals for student learning, and (b) expectations for academic performance and behavior. Students were also interviewed to investigate the extent to which they acknowledged these goals and expectations. Data were analyzed using constant comparison. Results suggested that goals and expectations of DM/LP and EI/SR teachers were distinctly different and that comments from students in the EI/SR teachers' classes did not reflect their teachers' goals and expectations. Dynamical system theory was used to conceptualize value orientations as attractors within the educational ecosystem. Teachers working from weak EI/SR value attractors may be limited by learner, instructional, and contextual constraints.     

Evolution of Higher Education Finance in Australia

Central policymakers are becoming more aware of the possibilities of implementing their policies by using 'softer' discretionary financial instruments in preference to 'harder' directives and conditions attached to granted funds. A typical technique within this softer approach is to offer block grants to any target organization which contracts to pursue specific policy goals and to account for their achievement. Policymakers effectively perceive themselves as 'quasi-consumers', prepared to 'buy' the achievements of their target organizations. Following its new self-perception, the Commonwealth has 'invited' higher education institutions to 'enjoy' the financial benefits of its new Unified National System. Membership is open, however, only to those institutions which undertake to achieve specific organizational reforms desired by the Commonwealth. Moreover block recurrent grants flow to member institutions only after teaching and research targets have been individually negotiated and contracted.
