A lot of students think that learning is only in class. If students use two extra steps, most students
will not forget what they learned in class. To achieve effective learning, students need to follow
two extra steps in the three strategic learning processes.
The key to success is by following these three strategies. Review is essential to student success.
Unless content is reviewed by students shortly after it is learned, it will soon be forgotten. To avoid
forgetting what you learned, it is recommended to review daily.
It is also recommended to reduce large volumes of notes into point form and to paraphrase what
you have learned. Other helpful tips include creating concept maps and diagrams; creating fact,
concept or vocabulary cards and using visualization to better connect to what you learned. These
are all important tools to helping students better understand and memorize lesson content.
The key to achieving academic success cannot be directly correlated to one specific area. Rather
it requires students to be overall rounded in many different aspects. This includes attending class
regularly to keep pace with the class. Falling behind in studies or homework can be detrimental
to academic success and can induce stress onto students. Participating in class activities and
discussions are also vital parts of learning and applying concepts learned. On the other hand,
taking good, concise notes will always help in the long run when reviewing for tests and exams.
To sum it all up, strategic learning is the password for many academic achievements. Being
exposed to knowledge is the first step in the journey, the fact that young scholars can learn and
be a part of history is a phenomenal step in furthering their search to success. Reviewing notes,
in the way the young individual wishes, by himself/herself, or with a good friend, will help
him/her to understand what has been learned in a way s/he understands. Lastly practice is a great
way to memorize what has been learned, when practice achieves its full potential, the individual
won’t only be entitled for a good mark, but also a way to view, understand and think of things.
Those three attributes will help scholars become more successful, but it’s important to one as it is
to the other, and each and every person should find the learning strategies effectual for him/
herself, and in extremely exceptional occasions even invent or innovate new strategies.

Forty-nine foreign heads of state were in Banjul for the summit. All looked happy, and why
not? Had they not escaped from troublemakers in their home countries? They saw ahead of
them a stay free from trouble here, in the Gambia, a country everyone kept calling 'the land of
Kunta-kinteh'. All hoped to get from their stay as much rest as possible. Of course, at some
point, they would each other take the floor and, as fans back home expected, address the
summit, but this was something that they could do with little or no effort at all. For Gambians,
though, the presence of so many visiting dignitaries was not fun. True, forty-nine heads of state

Ukosefu wa sera mwafaka kuhusu ardhi nalo ni tatizo jingine linalotatiza kilimo nchini. Serikali haijaweka
sera mahususi kuhusu matumizi ya ardhi. Wananchi wengi huongozwa na taratibu za utamaduni za nasaba
zao. Taratibu hizi hupendekeza ugawaji wa ardhi kwa minajili ya urithi kulingana na warithi waliopo. Si
ajabu kuwa kote nchini, ardhi inayofaa kwa kilimo imekatwakakatwa vipande vidogovidogo ambavyo
haviwezi kuwa na faida kwa zaraa.
Kushindwa kwa mkulima kuongeza virutubishi ardhini ni changamoto nyingine inayokabili kilimo nchini.
Ulimaji wa kile kipande cha ardhi mwaka nenda mwaka rudi, bila kukipa nafasi ya kukipumzisha, huufanya
mchanga kupoteza virutubishi muhimu vinavyohitajiwa na mimea. Hili nalo huchangia kupunguza
uzalishaji wa mazao. Ili kutatua tatizo hili, wakulima wengi hukimbilia mbolea za kisasa ambazo badala ya
kumsaidia, humwongezea madhila. Mbolea hizi zinatambulikana kuchangia uchafuzi wa mchanga na
ardhi.
Mabadiliko ya hali ya anga nayo huongeza msururu wa madhila ya mkulima. Mabadiliko haya yamemfanya
mkulima kushindwa kupanga wakati anaotakiwa kutayarisha shamba, kupanda, kupalilia, kunyunyizia
dawa na kadhalika kwa sababu mvua imekuwa adimu. Badala yake panakuwa na vipindi virefu vya kiangazi
ambavyo huathiri bidii za mkulima. Maji nayo yanaendelea kupungua na wakulima wengi hawawezi
kukimu mahitaji ya unyunyizaji maji mashambani.
Maradhi pamoja na wadudu waharibifu kama vile viwavi, kupena mbung’o ni changamoto nyingine
inayotatiza juhudi za mkulima hapa nchini. Haya hupunguza uzalishaji wa mkulima au wakati mwingine
kupunguza mifugo au mimea yake.
Kwa sadfa, iwapo mkulima ataweza kuzalisha mazao licha ya msururu huu wa vikwazo; ana tatizo jingine
linalomngojea: ukosefu wa soko kwa mazao yake. Aghalabu, maeneo mengi yanayotoa mazao ya kilimo
kwa wingi huwa na matatizo ya usafiri. Njia na barabara huwa mbovu na hazipitiki. Mazao mengi huwa
hayafiki sokoni kwa wakati na huwa ni hasara kwa wakulima.
Maswali
(a) Ipe taarifa hii anwani mwafaka. (Alama1)
(c) Ni kwa nini wataalamu wa kilimo waliopo hawawafai wakulima nyanjani? (Alama4)
(d) Eleza sababu zozote nne zinazokinga mkulima kuzalisha mazao ya kutosha. (Alama 4)
(e) Kwa nini watu wengi wameacha kutegemea kilimo kama njia ya ajira (Alama 2)
SWALA LA 2: UFUPISHO
Ajira ya watoto ni tatizo sugu linalokumba ulimwengu wa sasa, hasa katikanchi zinazoendelea. Jambo la kusikitisha
ni kwamba hivi ndivyo ilivyyo katika nchi nyingi za ulimwengu huu. Kuna idadi kubwa ya watoto wanaoajiriwa katika
Nyanja mbalimbali za jamii. Zipo sababu nyingi zinazowasukuma watoto kutafuta ajira barani Afrika kwa mfano,
familia nyingi huishi maisha ya ufukara hivi kwamba hushindwa kuyatimiza mahitaji muhimu hususan kwa watoto.
Kupanda kwa gharama ya maisha kunazidisha viwango vya umaskini. Ukosefu wa lishe pia huwafanya watoto
kutoroka nyumbani kutafuta ajira. Janga la UKIMWI limesababisha kuwepo kwa idadi kubwa ya mayatima
wanaoshia kutafuta ajira ili kuyakimu maisha. UKIMWI umezifanya familia nyingi pia kuwaondoa watoto shuleni ili
waweze kuajiriwa kwa lengo la kuzalisha pato la familia hizo. Watoto wengine hutoroka makwao kwasababu ya
maonevu. Maonevu haya ni kama vile kupigwa, kutukanwa kila wakati, kunyanyaswa kijinsia na kadhalika. Huko
nje hutaabishwa kimwili na kiakili. Hufanyishwa kazi za sulubu zenye malipo duni au wasilipwe kabisa. Hili
huwasononesha na kuathiri afya yao.
Wengine hujiingiza katika vitendo vya jinai pale wanapokosa ajira. Huchukua sheria mikononomwao, wakaendeleza
vitendo vya ukatili kama vile kuwahangaisha watu na kupora mali yao au hata kuwakaba roho. Aidha, wengine
hujikuta kwenye madanguro ambako huendesha biashara.
Uundaji wa umoja wa Afrika hivi majuzi ni hatua muhimu ya kushughulikia matatizo ya Afrika kamavile ajira ya
watoto, kuzorota kwa miundo msingi, magonjwa, njaa, umaskini, ufisadi na ukabila. Katika kushughulikia haki za
watoto, nchi za Afrika hazina budi kuzingatia masharti yaliyowekwa na Umioja na Mataifa kuhusu haki za watoto.
Nchi hizi basi lazima zishugulikie haki za watoto kupitia sharia za nchi. Watoto ni rasilmali muhimu na ndio tumaini
la kuwepo kwa kizazi cha binadamu.

Mtoto huyo na wenzake walianza kurushiana kijiwe hicho. Baada ya muda kikaanza kuongezeka
umbo na kuonekana kama kiwiwili cha binadamu. Kikaanza kuwakimbiza wale watoto wawili.
Kutokana na ukelele wao, watu walikuja kutazama ni nini kilikuwa cha mno. Walipofika
walikutana ana kwa ana na dubwana hilo. Lilizidi kuongeza kwa umbo na likawameza wote
pamoja na mifugo wao. Wachache waliojaribu kukimbia liliwashika kwa mikono yake mirefu na
mipana. Kwa bahati njema kulikuwa na mama mmoja aliyeyaona hayo yote. Alikuwa mbali kiasi
na hapo. Aliteremka kutoka kilele cha mlima na kuwapata wakulima makondeni na sawia
akawajuza kuhusu kilichomwogofya sana. Wote wakaacha shughuli zao na wakatwaa silaha zao
wakaelekea soko kuu.
Dude sasa lilikuwa limejilaza baada ya shibe. Wakulima wale waliwachagua watu sita ambao
walijulikana kwa ushujaa wao. Pamoja walilinyemelea lile nyangarika na kulikata mara moja.
Lilitoa mkoromo mkuu kabla halijakata kamba. Punde, wanakijiji kwa uangalifu mkubwa
walitoboa tumbo lake wakitarajia kupata maiti za wapenzi wao. Wote walijawa na furaha kuu
walipoona wapenzi wao wakichomoza kutoka tumboni, mmoja baada ya mwingine hadi akatoka
yule wa mwisho. Mbuzi, kondoo na ng’ombe wote walitoka mmoja mmoja.
Siku hiyo kuliandaliwa sherehe kuu ya kumshukuru muumba kwa wema wake. Watoto
wakashauriwa wasithubutu kuchezea vitu wasivyojua. Hadithi yangu inaishia hapo.
