This study examines the condition on whether or not there is an advantage on integrating manipulatives in the instruction against traditional teaching involving concept building and students’ performance in geometry. To well achieve this objective, 48 Grade-9 students from a remote public school and island in the Philippines were invited and were then divided into control and experiment groups. After such inferences, empirical results showed that there was no significant mean difference on the scores between the two groups, which implies that one method does not outperform the other. Indeed, post-evaluation revealed that there are other variables which trigger the variation of scores from these groups, respectively, as shared by the subjects themselves. Thus, it is proposed that future relevant researches, shall peek into those variables that can nonetheless support the efficacy of intended curriculum contents and correspondingly address the diverse learning styles.

Camotes Islands is noted of its Camotes Sea as one of the fishing grounds in the Philippines. Extraction of the marine resources including holothurians in this fishing ground has been felt by the fishermen; hence, this study was conducted in order to find out its gleaning methods used, species gleaned, extraction rate and perception on the distribution of holothurians in the four municipalities of Camotes Islands which are San Francisco, Poro, Tudela and Pilar. Interview guide and actual field visits in the areas were used to gather the data. Results show that gleaning methods of gathering holothurians in Camotes Islands were handpicking, using bolo, water goggles, pointed wood, iron bars and by spears both in day and night operations. Frequently gleaned sea cucumber spe cies are Stichopus hermanni, Bohadschia paradoxa, Bohadschia marmorata, Stichopus horrens, Holothuria nobilis, Stichopus variegatus and Holothuria pulla which are also the species that were caught throughout the year.The size of the Holothurians gathered measures from 5-10 cm and the perceived distribution distance of gleaned holothuria in the site is 1-5 m. The amount of catch is 1/2 kilo per 1-2 hours gleaning time followed by "no catch" and the third is 0.51 to 1.0 kg and the gleaning frequency of holothurians in the entire Camotes Islands is 2-4 times a week.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
