RT journal article T1 Relación entre creencias sobre resolución de problemas, creencias epistemológicas, nivel académico, sexo y desempeño en resolución de problemas: un estudio en educación secundaria T2 The relationship among beliefs about problem solving, epistemological beliefs, grade level, sex, and problem solving achievement: A study in secondary school A1 Alabau Gonzalvo, Javier A1 Solaz-Portoles, Joan Josep A1 Sanjosé López, Vicente K1 Creencias epistemológicas K1 creencias sobre resolución de problemas K1 nivel en la educación secundaria K1 sexo K1 resolución de problemas K1 Epistemological beliefs K1 beliefs about problem solving K1 grade level K1 sex K1 problem solving AB The first purpuse of this investigation was to study the effects of sex and grade level on secondarystudents’ beliefs about epistemology and problem solving. The second purpuse was to analyze the contributionof both belief systems, grade level, and sex to problem solving achievement. One hundred and forty-four HighSchool students, 9th and 11th grade students, took part in the study. Two questionnaires (Schommer and StageKloosterman’s questionnaires) and a problem solving test (two word problems of the PISA tests) wereadministered to these students. Two ANOVAs, an ANCOVA, and a multiple regression analysis were carried outfrom data obtained in the investigation. In the light of the foregoing, it can be concluded that: a) The higher isthe grade level of secondary students, the more appropriate are beliefs about epistemology and problem solving;b) Students’ sex has a significant influence on epistemological beliefs, but not on beliefs about problem solving;and c) Students’ problem solving achievement depends on grade level and their beliefs about problem solving,and these beliefs are themselves dependent on students’ epistemological beliefs.
