Emancipatory or instrumental? Students’ and teachers’ perceptions of the implementation of the EcoSchool program

Abstract

We present findings of a mixed method evaluation study of the EcoSchool program in the Czech Republic. The innovativeness of this study is its specific focus on implementation strategies rather than learning outcomes. Using data from 148 students and 65 teachers from 54 different schools involved in the program, we investigated perceptions about the nature of the implementation and the impact of the approach on students’ and teachers’ feelings of ownership of success, loss of meaning of the program, or satisfaction with their participation in the EcoSchool program. The findings support the relevance of the emancipatory approach: students’ perceived participation predicts both their satisfaction with the program and perceived ownership of the success of their EcoTeams. Unexpectedly, the study also found that another factor predicting the program’s effectiveness is the level of students’ control over nonparticipating students.     

Post-collection acidification of spot urine sample is not needed before measurement of electrolytes

IntroductionKidney stone formers can have higher oxalate and phosphate salt amounts in their urine than healthy people and we hypothesized that its acidification may be useful. The study aims to compare results of urine concentrations of calcium, magnesium, and inorganic phosphorus in the midstream portion of first voided morning urine samples without (FMU) and with post-collection acidification (FMUa) in kidney stone patients.Materials and methodsThis is a prospective single center study. A total of 138 kidney stone patients with spot urine samples were included in the study. Urine concentrations of calcium, magnesium and inorganic phosphorus were measured with and without post-collection acidification. Acidification was performed by adding 5 µL of 6 mol/L HCl to 1 mL of urine.ResultsThe median age (range) of all participants was 56 (18-87) years. The median paired differences between FMU and FMUa concentrations of calcium, magnesium, and inorganic phosphorus were: - 0.040 mmol/L, 0.035 mmol/L, and 0.060 mmol/L, respectively. They were statistically different: P < 0.001, P < 0.001, P = 0.004, respectively. These differences are not clinically significant because biological variations of these markers are much higher.ConclusionsNo clinically significant differences in urinary calcium, magnesium, and inorganic phosphorus concentrations between FMU and FMUa in patients with kidney stones were found.
