The construction sector is becoming more important every day in Mexico, due to population growth and its multiple needs for urban infrastructure, requiring for this purpose to have committed workers who allow the achievement of business objectives of development and growth. The objective of this research is to measure the degree of labor commitment of a construction company located in Mexico, with the purpose of influencing the improvement of the behavior of its personnel. First, a quantitative measurement was made and then the information was supplemented by qualitative interviews. A total of 30 workers that make up the company participate. The results indicate that the workers are moderately committed, because their participation and loyalty are not well defined. In addition, they have medium identification and belonging. Therefore, it is suggested to implement a strategic program for a culture of participation (empowerment), which includes greater initiative and autonomy for employees when sharing information and giving them greater control over their work performance, increasing trust, responsibility, and commitment to the company.

The paper shows the research results of fourth grade pupils’ knowledge of Croatian orthography, more specifically of writing words containing č and ć with respect to exposure to such words in Croatian language textbooks. Both textbooks comprise in total 4552 lexical units containing č and ć, of which 1436 distinctive words. The research established which words in the textbook for Croatian language are frequent and which are less frequent. Using dictation, we checked knowledge of accurate writing of 10 most frequent and 22 less frequent words. The results indicate that pupils were statistically significantly more successful in writing more frequent words than in writing less frequent words. A statistically significant difference was not found in pupil achievement with respect to gender. For successful learning of orthography, pupils should be exposed to texts which are saturated with such content.Key words:  Croatian language teaching methodology; orthographic knowledge; primary education; textbooks.  --- SažetakU radu smo istražili pravopisno znanje hrvatskoga jezika učenika četvrtoga razreda u pisanju riječi koje sadrže č i ć s obzirom na izloženost tim riječima u udžbenicima hrvatskoga jezika. U oba udžbenika evidentirane su ukupno 4552 riječi koje sadrže č i ć, a od toga je 1436 riječi različito.Istraživanjem smo utvrdili koje su riječi u udžbeniku hrvatskoga jezika frekventne, a koje manje frekventne te smo s pomoću kontrolnoga diktata provjerili znanje pravilnoga pisanja 10 najfrekventnijih i 22 najmanje frekventne riječi. Rezultati pokazuju da su učenici bili statistički značajno uspješniji u pisanju frekventnijih riječi nego u onima manje frekventnima. Nije dobivena statistički značajna razlika u uspjehu učenika s obzirom na spol. Da bi učenje pravopisnih sadržaja bilo uspješno, učenike je potrebno izlagati jezičnometodičkim predlošcima koji su zasićeni tim sadržajem.Ključne riječi:  metodika hrvatskoga jezika; pravopisno znanje; primarno obrazovanje; udžbenici.
