In order to discuss various ways of learning as part of teacher education, it is important to clarify the learning mechanism of each student. However, no research focusing on mindset has been conducted in teacher education research in Japan. In this study, as a first step to clarify the teachers’ mindset concerning science, differences between implicit theories of intelligence and preservice teachers’ mindset about teaching competences were explored and their perceptions about the competences necessary for science were analyzed. The results of the research can be summarized in the following four points: (1) Preservice teachers believe that teacher competences can grow more than intelligence. (2) First-year university students have greater belief that teacher competences can be developed than do second-year students. (3) Preservice teachers consider having the ability to experiment; having abundant class contents or peripheral knowledge; and raising the interest, motivation, and curiosity of children as teacher competences necessary for science. (4) Second-year university students value the need for children-centered classes, which may have created a difference in their mindset about teaching competences compared to first-year students.

We treated 3 patients who developed respiratory disorders due to aluminum silicate, a principal component of “Kitty litter” (cat dirt). Case 1 was a 37-year-old woman with dyspnea treated for bronchial asthma for 3 months from about September 1995. Dyspnea was exacerbated after inhalation of powder from Kitty litter. On admission, disturbance of consciousness and marked hypoxemia were noted, but the patient recovered through respiratory management. Bronchoscopy showed white sputum in each segment of the bronchi. Case 2 was a 48-year-old woman with a cough exacerbated from about November 1998. Moist rales were present in expiration on chest auscultation. Symptoms were resolved by the administration of bronchodilators and expectorants. Case 3 was a 45-year-old woman with dyspnea treated for bronchial asthma since about March 1998 without improvement. Moist rales were present in bilateral lung fields during inspiration and expiration. A diagnosis of pneumonitis was made based on chest computed tomography (CT) findings recovered by bronchodilators and expectorants. From the information obtained by inquiry about the disorder, all 3 patients were considered have problems related to Kitty litter. Silica was present in the sputum of all 3 in analysis using an X-ray microanalyzer. Kitty litter causes severe symptoms on massive inhalation and respiratory disorders by inhalation of even a small amount over a long period. Precaution are thus required for indoor use.
