Metacognition and self-regulated learning are skills that contribute to student success, but few studies have examined these topics within a community college context. We addressed this lack of understanding by asking community college biology students to metacognitively reflect on their learning strategies. We took a novel approach in our analysis by investigating how learning strategies potentially differed based on race, age, gender, and final course grade. With some exceptions, we found little evidence to suggest that such differences existed. Notably, we found that learning strategies did not differ between high-achieving and low-achieving students, which contradicts previous studies. We offer several possible explanations for these preliminary results, which include misrepresentation by students in their reflections, external and internal barriers to studying, potential flaws in our survey instrument, and students not effectively using learning strategies. We suggest replication of this study with methodological changes to further investigate any potential differences that may exist among these groups of students. Our research is an example of how classroom action research can provide insight into how students learn, which empowers us to make evidence-based changes in our teaching.

Analysis of microaerophilic protozoan Trichomonas vaginalis to examine its sensitivity to oxygen and oxygen products and the role of antioxidant enzymes in the protozoa reveals that the amitochondrial flagella of the protozoa respond to oxygen tensions and the metromidazole-sensitive strains are less sensitive to oxygen levels than the metronidazole-resistant strains. The antioxidant enzymes in the organism indicate the presence of azide-sensitive, cyanide-insensitive superoxide dismutase activity and high methanethiol, propanethiol and H2S levels.

Maternal and Child Health Services (MCHS) provide ideal settings for oral disease prevention. In Victoria (Australia), child mouth-checks (Lift-the-Lip) and oral health promotion (OHP) occur during MCHS child visits. This study trialled Tooth-Packs (OHP resources, toothbrushes, toothpastes) distribution within MCHS to (i) assess the impacts of Tooth-Packs distribution on child and family oral health (OH) behaviours and knowledge, including Maternal and Child Health Nurses (MCHN) child referral practices to dental services, and (ii) determine the feasibility and acceptability of incorporating Tooth-Packs distribution into MCHN OHP practices. A mixed-methods evaluation design was employed. MCHN from four high-needs Victorian Local Government Areas distributed Tooth-Packs to families of children attending 18-month and/or 24-month MCHS visits (baseline). Families completed a questionnaire on OH and dietary practices at baseline and 30-month follow-up. Tooth-Packs distribution, Lift-the-lip mouth-checks and child OH referrals were conducted. Guided discussions with MCHN examined intervention feasibility. Overall, 1585 families received Tooth-Packs. Lift-the-lip was conducted on 1493 children (94.1%). Early childhood caries were identified in 142 children (9.5%) and these children were referred to dental services. Baseline to follow-up behavioural improvements (n  = 230) included: increased odds of children having ever seen an OH professional (OR 28.0; 95% CI 7.40–236.88; p  < 0.001), parent assisted toothbrushing twice/day (OR 1.76; 95% CI 1.05–3.00; p  = 0.030) and toothpaste use >once/day (OR 2.82; 95% CI 1.59–5.24; p  < 0.001). MCHN recommendations included distribution of Tooth-Packs to at-risk children <12-months of age. MCHS provide an ideal setting to enable timely family-centred OHP intervention and adoption of good OH behaviours at an early age. [ABSTRACT FROM AUTHOR]
