A summary of research relating to reading in the intermediate grades [PDF]
, 1963 Purpose: To develop and evaluate a method of quick perception with geography vocabulary to see if; (a) quick perception accelerates growth in comprehension, (b) effects speed of reading, and (c) improves reading ability.

On the Generalized Order-k Jacobsthal and Jacobtshal-Lucas Numbers
Fundamentals of Contemporary Mathematical SciencesThe classic Jacobsthal numbers were generalized to k sequences of the generalized order-k Jacobsthal numbers and then have been studied by several authors.

On k-periodic binary recurrences [PDF]
, 2012 We apply a new approach, namely the fundamental theorem of homogeneous linear recursive sequences, to k-periodic binary recurrences which allows us to determine Binet's formula of the sequence if k is given.

A Note on Bi-Periodic Leonardo Sequence
Armenian Journal of MathematicsIn this work, we define a new generalization of the Leonardo sequence by the recurrence relation $GLe_n=aGLe_{n-1}+GLe_{n-2}+a$ (for even $n$) and $GLe_n=bGLe_{n-1}+GLe_{n-2}+b$ (for odd $n$) with the initial conditions $GLe_0=2a-1$ and $GLe_1=2ab-1 ...

On The Hyperbolic k-Mersenne And k-Mersenne-Lucas Octonions
Kragujevac Journal of MathematicsIn this paper, we introduce the hyperbolic k-Mersenne and k-Mersenne-Lucas octonions and investigate their algebraic properties. We give Binet’s formula and present several interrelations and some well-known identities such as Catalan identity, d’Ocagne ...

On the Leonardo quaternions sequence
Hacettepe Journal of Mathematics and StatisticsIn the present work, a new sequence of quaternions related to the Leonardo numbers -- named the Leonardo quaternions sequence -- is defined and studied. Binet's formula and certain sum and binomial-sum identities, some of which derived from the mentioned
